I made a 'first draft' of a design for the [[Well-drilling Rig]] and would like to work on either a preliminary design for another of the machines or make drawings of something like the tractor bucket or backhoe, etc. I want to work on something else in the next few days to weeks so that the community has time to comment on the well-drilling rig and after that time I can go back and make any revisions to that that the community comes up with. I would like to know what the most important item is that is not already being worked on by someone else. I had read that someone is working on CAD files for the tractor and that the torch table is cutting some of the pieces for it so that sounds like it is covered, does the liberator have CAD drawings, or are there things that need formal CAD drawings (rather than just blender mockups). -[[User:Andrew Buck|Andrew Buck]] 08:44, 18 May 2011 (PDT)<br /> <br /> <br /> :Andrew - i added you to the CAD team. We have a number of people - and after the production run, we aim to leverage all this assistance to generate CAD for about 20 other devices - in which we'll need all the help we can get. We plan on then prototyping Sep 1-30 in the Factor e Farm Convergence (to be blogged). Spread the word on the forums, and let's keep building our CAD team - Marcin<br /> <br /> :: I will do the survey and add myself to the relevant CAD team (thank you for pointing me to the CAD team by the way, I hadn't found it on the help pages). I would like to know what to be working on right now though. Of the 20 devices you plan to build in the next phase I would assume very few, if any have formal drawings made. Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two. The well drilling rig uses some of both systems as I wasn't sure what you typically worked with but if I know the preferred system it is easier to do that right from the get go. -[[User:Andrew Buck|Andrew Buck]] 09:14, 18 May 2011 (PDT)<br /> <br /> :: I have added renderings of a couple of the models I finished so far. I have models for the [[Universal Rotor]] and the [[Backhoe]]. I have added a PNG version of a 2d sketch of the rotor (the wiki won't let me upload SVG files), if you or someone else on the farm there could add dimensions to it as indicated in the note that would be cool. The dimensions it has now should be reasonably close to the one you have there but it would be nice to have an accurate model for discussion of changes to be made before the next prototype. I plan to keep modeling, but am running out of ideas of things to work on until I do the second drafts of these models, any suggestions on where to go next would be appreciated. -[[User:Andrew Buck|Andrew Buck]] 22:09, 19 May 2011 (PDT)<br /> --<br /> <br /> == Wikinames/solid GVCS list ==<br /> <br /> Hi Marcin, can you please confirm the [[Wikinames | list]] here to ensure that all 50 machines are accounted for?

We're just 350 students and 40 faculty, have no departments, offer just one interdisciplinary major in human ecology, and have our campus on the ocean at Mount Desert Island, Maine, complete with two 100+ acre farms.<br /> <br /> I'm guessing you have a lot on your plate, especially around the holidays. But if you could drop me an email at dcollins@coa.edu or, better yet, call me at 207-266-5161, I'd really like to talk with you.<br /> <br /> Something to consider: would you ever give a commencement address at graduation?

This system would not have that downside.<br /> <br /> Not sure how to do it, but possible by using a separate anaerobic digester and pretreating the effluent and perhaps diluting it too, before administering it into the hydroponic system. Methane production is unavoidable and a problem, so perhaps best to burn that and use the waste heat for heating up a greenhouse and using CO2 for injection to the greenhouse (for use by plants).<br /> <br /> See [https://www.ncbi.nlm.nih.gov/pubmed/22437012 here] and [https://www.sciencedirect.com/science/article/abs/pii/S0304389406013951 here].<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 17:39, 28 March 2020 (UTC)<br /> <br /> ----<br /> I forget when it was (few years ago?) I was geeking out about aquaponics, and was hearing of various catastrophic feedback loops in aquaponic systems. Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart.<br /> <br /> One solution i came across was sensor and camera based monitoring (some even had internet viewing)<br /> <br /> OTS these were VERY expensive, but perhaps some sort of arduino device?<br /> <br /> Don't know if i made a page for it yet. I did make a page for a sort of lab venier probe logger type device, perhaps we can use that page?<br /> <br /> Either way would that be an option?<br /> <br /> <br /> '''SECONDLY'''<br /> <br /> On the whole modular approach of yours that seems good as well<br /> <br /> I was plotting some sort of biogas/syngas -> CNG upgrader + compressor system<br /> <br /> Supposedly water scrubbing works? so that seems SOMEWHAT simple<br /> <br /> Main problem is compressing a flammible gas to high pressure<br /> <br /> I know marcin had some sort of pvc pipe storage in the works, was that lower pressure<br /> <br /> ANYWAYS that seems like what the best way to send that off would be<br /> <br /> For the C02 enriching, that works great, perhaps either a low-NOx burner?<br /> <br /> I was trying to find direct methane fuel cells, as that would be wonderful, all seem very experimental as of now<br /> <br /> Another way would be to generate co2 in the "Central Burner" area (where the gassifier hydronic heater is) and have either a near pure (ie scrubbed, yet more complex) or concentrated plumbed CO2 line? More complex, but may lead to more co-generation in using the methane. Granted CHP for the greenhouse works great if the area is cold<br /> <br /> Also CO2 Sensors would be useful for the whole enriching thing to be able to control the precise levels<br /> <br /> Along the lines of effulent and nutrient mixes, how do we go about testing this (sensor wise, not plant growth wise), i know Dissolved Oxygen Sensors, PH sensors, temperature probes are easy, but nutrients etc, what would be needed<br /> <br /> I think making a modification of the IBC container WWT system could be used? (Slow sand filter?)<br /> <br /> '''I'm kind of rambling on here, but altogether:'''<br /> *Seems like a good idea, and valid concern of "ecosystem?" collapse<br /> *This would allow for additional modularity perhaps (Fish Module, Anerobic Digester Module, Effluent Processor Module, Nutrient Manifold Module, Greenhouse Monitor Module, etc)<br /> *Course of action post COVID-19 work perhaps would be:<br /> **Sensor "Brain Unit" and modular probes etc<br /> **Biogas->Methane Scrubber<br /> **More Waste Water Treatment, and Greywater/effulent water reuse tech etc<br /> **Nutrient "Recepies" and "dosing" devices<br /> <br /> I don't know if i got what you were trying to get across, so if i missed something feel free to clarify if need be. Those are my thought on that bit.<br /> <br /> --[[User:Eric|Eric]] ([[User talk:Eric|talk]]) 19:25, 28 March 2020 (UTC)<br /> <br /> <br /> ----<br /> Hey Eric,<br /> <br /> Thanks for the reply. Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-). Once they die, nutrient balance gets distorted. Also, if just eating the fish (the fish are consumed too), there are temporary inbalances.<br /> <br /> ::So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite labourious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> ::For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> ::Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the biogas until someone comes alone and burns it with a gas lighter).<br /> I'm also not entirely sure whether it is worth burning it at all in which case you don't need to foresee this storage option (depends on amounts of biogas/methane that is produced). Also, doesn't it depend on the bacteria in the digester, and are there any ways to influence the bacteria in the digester (by adding a yeast, ... ?)<br /> <br /> The thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> <br /> Besides the digester/effluent treatment design, there is also the hydroponic system itself. It should be mountable on a an A-frame with 12 pipes (in which a hole is drilled for the plants). For A-frame design, see Vertical Farming page links. I have seen that regular plastic plant pots (with holes, also called net pots) are often used to put inside these pipes and then filled with a substrate (like sand, gravel, vermiculite, perlite, ...). If possible I rather not have it use plastic since I fear it may pass on chemicals into the plants, but I'm not sure whether there are any viable alternatives for plastic (perhaps bamboo may be an option if there is any bamboo that is thick enough and also it then needs to have the sections inside the bamboo removed so the water can flow through). Bioplastic net pots can also be an option (the pipe itself can just be a regular plastic to reduce costs, the net pots are probably the most important here to prevent contamination, if it occurs at all).<br /> Perhaps some core components like the pump (which manufacturer ?, ...) can be proposed. Also, I never really used a hydroponics system before, and am worried about root rot. I read somewhere that by having sufficient oxygen in the system this is avoided, but I'm not sure how this is achieved (through an air compressor ?, through incorporating some small waterfalls in the system ?, by putting the roots slightly out of the water, but I doubt roots can take up air when exposed to the air, and probably dry out/die then).<br /> <br /> Some commercial pipes/net pots/pumps/... can be found at<br /> * shop.amhydro.com (NFT systems)<br /> * hydrogarden.com (kits and systems)<br /> <br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

This system would not have that downside.<br /> <br /> Not sure how to do it, but possible by using a separate anaerobic digester and pretreating the effluent and perhaps diluting it too, before administering it into the hydroponic system. Methane production is unavoidable and a problem, so perhaps best to burn that and use the waste heat for heating up a greenhouse and using CO2 for injection to the greenhouse (for use by plants).<br /> <br /> See [https://www.ncbi.nlm.nih.gov/pubmed/22437012 here] and [https://www.sciencedirect.com/science/article/abs/pii/S0304389406013951 here].<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 17:39, 28 March 2020 (UTC)<br /> <br /> ----<br /> I forget when it was (few years ago?) I was geeking out about aquaponics, and was hearing of various catastrophic feedback loops in aquaponic systems. Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart.<br /> <br /> One solution i came across was sensor and camera based monitoring (some even had internet viewing)<br /> <br /> OTS these were VERY expensive, but perhaps some sort of arduino device?<br /> <br /> Don't know if i made a page for it yet.

More complex, but may lead to more co-generation in using the methane. Granted CHP for the greenhouse works great if the area is cold<br /> <br /> Also CO2 Sensors would be useful for the whole enriching thing to be able to control the precise levels<br /> <br /> Along the lines of effulent and nutrient mixes, how do we go about testing this (sensor wise, not plant growth wise), i know Dissolved Oxygen Sensors, PH sensors, temperature probes are easy, but nutrients etc, what would be needed<br /> <br /> I think making a modification of the IBC container WWT system could be used?

Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-). Once they die, nutrient balance gets distorted. Also, if just eating the fish (the fish are consumed too), there are temporary inbalances.<br /> <br /> ::So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite labourious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> ::For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> ::Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the biogas until someone comes alone and burns it with a gas lighter).<br /> I'm also not entirely sure whether it is worth burning it at all in which case you don't need to foresee this storage option (depends on amounts of biogas/methane that is produced). Also, doesn't it depend on the bacteria in the digester, and are there any ways to influence the bacteria in the digester (by adding a yeast, ... ?)<br /> <br /> The thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> <br /> Besides the digester/effluent treatment design, there is also the hydroponic system itself. It should be mountable on a an A-frame with 12 pipes (in which a hole is drilled for the plants). For A-frame design, see Vertical Farming page links. I have seen that regular plastic plant pots (with holes, also called net pots) are often used to put inside these pipes and then filled with a substrate (like sand, gravel, vermiculite, perlite, ...). If possible I rather not have it use plastic since I fear it may pass on chemicals into the plants, but I'm not sure whether there are any viable alternatives for plastic (perhaps bamboo may be an option if there is any bamboo that is thick enough and also it then needs to have the sections inside the bamboo removed so the water can flow through). Bioplastic net pots can also be an option (the pipe itself can just be a regular plastic to reduce costs, the net pots are probably the most important here to prevent contamination, if it occurs at all).<br /> Perhaps some core components like the pump (which manufacturer ?, ...) can be proposed. Also, I never really used a hydroponics system before, and am worried about root rot. I read somewhere that by having sufficient oxygen in the system this is avoided, but I'm not sure how this is achieved (through an air compressor ?, through incorporating some small waterfalls in the system ?, by putting the roots slightly out of the water, but I doubt roots can take up air when exposed to the air, and probably dry out/die then).<br /> <br /> Some commercial pipes/net pots/pumps/... can be found at<br /> * shop.amhydro.com (NFT systems)<br /> * hydrogarden.com (kits and systems)<br /> <br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

I never intended on becoming a college president and don't think I fit the mold of such a position, but I'm good at my job because I've always loved this place and love it now more than ever. Somehow, I think you'd love it too and would find yourself right at home. <br /> <br /> I'd like to find a way to get you here for a visit because I believe our campus could very well become something of a laboratory for Open Source Ecology. I know you already have such a lab in your Factor e Farm, but I thought you might like to consider partnering with an experimental college as a way of further testing your ideas. We're just 350 students and 40 faculty, have no departments, offer just one interdisciplinary major in human ecology, and have our campus on the ocean at Mount Desert Island, Maine, complete with two 100+ acre farms.<br /> <br /> I'm guessing you have a lot on your plate, especially around the holidays. But if you could drop me an email at dcollins@coa.edu or, better yet, call me at 207-266-5161, I'd really like to talk with you.<br /> <br /> Something to consider: would you ever give a commencement address at graduation?

This system would not have that downside.<br /> <br /> Not sure how to do it, but possible by using a separate anaerobic digester and pretreating the effluent and perhaps diluting it too, before administering it into the hydroponic system. Methane production is unavoidable and a problem, so perhaps best to burn that and use the waste heat for heating up a greenhouse and using CO2 for injection to the greenhouse (for use by plants).<br /> <br /> See [https://www.ncbi.nlm.nih.gov/pubmed/22437012 here] and [https://www.sciencedirect.com/science/article/abs/pii/S0304389406013951 here].<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 17:39, 28 March 2020 (UTC)<br /> <br /> ----<br /> I forget when it was (few years ago?) I was geeking out about aquaponics, and was hearing of various catastrophic feedback loops in aquaponic systems. Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart.<br /> <br /> One solution i came across was sensor and camera based monitoring (some even had internet viewing)<br /> <br /> OTS these were VERY expensive, but perhaps some sort of arduino device?<br /> <br /> Don't know if i made a page for it yet.

More complex, but may lead to more co-generation in using the methane. Granted CHP for the greenhouse works great if the area is cold<br /> <br /> Also CO2 Sensors would be useful for the whole enriching thing to be able to control the precise levels<br /> <br /> Along the lines of effulent and nutrient mixes, how do we go about testing this (sensor wise, not plant growth wise), i know Dissolved Oxygen Sensors, PH sensors, temperature probes are easy, but nutrients etc, what would be needed<br /> <br /> I think making a modification of the IBC container WWT system could be used?

Those are my thought on that bit.<br /> <br /> --[[User:Eric|Eric]] ([[User talk:Eric|talk]]) 19:25, 28 March 2020 (UTC)<br /> <br /> <br /> ----<br /> Hey Eric,<br /> <br /> Thanks for the reply. Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-). Once they die, nutrient balance gets distorted. Also, if just eating the fish (the fish are consumed too), there are temporary inbalances.<br /> <br /> ::So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite labourious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> ::For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> ::Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the biogas until someone comes alone and burns it with a gas lighter).<br /> I'm also not entirely sure whether it is worth burning it at all in which case you don't need to foresee this storage option (depends on amounts of biogas/methane that is produced). Also, doesn't it depend on the bacteria in the digester, and are there any ways to influence the bacteria in the digester (by adding a yeast, ... ?)<br /> <br /> The thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> <br /> Besides the digester/effluent treatment design, there is also the hydroponic system itself. It should be mountable on a an A-frame with 12 pipes (in which a hole is drilled for the plants). For A-frame design, see Vertical Farming page links. I have seen that regular plastic plant pots are often used to put inside these plant pots (inserted to the pipes) and then filled with a substrate (like sand, gravel, vermiculite, perlite, ...). If possible I rather not have it use plastic since I fear it may pass on chemicals into the plants, but I'm not sure whether there are any viable alternatives for plastic (perhaps bamboo may be an option if there is any bamboo that is thick enough and also it then needs to have the sections inside the bamboo removed so the water can flow through. Perhaps some core components like the pump (which manufacturer ?, ...) can be proposed. Also, I never really used a hydroponics system before, and am worried about root rot. I read somewhere that by having sufficient oxygen in the system this is avoided, but I'm not sure how this is achieved (through an air compressor ?, through incorporating some small waterfalls in the system ?, by putting the roots slightly out of the water, but I doubt roots can take up air when exposed to the air, and probably dry out/die then). <br /> <br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

This system would not have that downside.<br /> <br /> Not sure how to do it, but possible by using a separate anaerobic digester and pretreating the effluent and perhaps diluting it too, before administering it into the hydroponic system. Methane production is unavoidable and a problem, so perhaps best to burn that and use the waste heat for heating up a greenhouse and using CO2 for injection to the greenhouse (for use by plants).<br /> <br /> See [https://www.ncbi.nlm.nih.gov/pubmed/22437012 here] and [https://www.sciencedirect.com/science/article/abs/pii/S0304389406013951 here].<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 17:39, 28 March 2020 (UTC)<br /> <br /> ----<br /> I forget when it was (few years ago?)

More complex, but may lead to more co-generation in using the methane. Granted CHP for the greenhouse works great if the area is cold<br /> <br /> Also CO2 Sensors would be useful for the whole enriching thing to be able to control the precise levels<br /> <br /> Along the lines of effulent and nutrient mixes, how do we go about testing this (sensor wise, not plant growth wise), i know Dissolved Oxygen Sensors, PH sensors, temperature probes are easy, but nutrients etc, what would be needed<br /> <br /> I think making a modification of the IBC container WWT system could be used?

Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-). Once they die, nutrient balance gets distorted. Also, if just eating the fish (the fish are consumed too), there are temporary inbalances.<br /> <br /> ::So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite labourious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> ::For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> ::Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the biogas until someone comes alone and burns it with a gas lighter).<br /> I'm also not entirely sure whether it is worth burning it at all in which case you don't need to foresee this storage option (depends on amounts of biogas/methane that is produced). Also, doesn't it depend on the bacteria in the digester, and are there any ways to influence the bacteria in the digester (by adding a yeast, ... ?)<br /> <br /> The thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> <br /> Besides the digester/effluent treatment design, there is also the hydroponic system itself. It should be mountable on a an A-frame with 12 pipes (in which a hole is drilled for the plants). I have seen that regular plastic plant pots are often used to put inside these plant pots (inserted to the pipes) and then filled with a substrate (like sand, gravel, vermiculite, perlite, ...). If possible I rather not have it use plastic since I fear it may pass on chemicals into the plants, but I'm not sure whether there are any viable alternatives for plastic (perhaps bamboo may be an option if there is any bamboo that is thick enough and also it then needs to have the sections inside the bamboo removed so the water can flow through. Perhaps some core components like the pump (which manufacturer ?, ...) can be proposed. Also, I never really used a hydroponics system before, and am worried about root rot. I read somewhere that by having sufficient oxygen in the system this is avoided, but I'm not sure how this is achieved (through an air compressor ?, through incorporating some small waterfalls in the system ?, by putting the roots slightly out of the water, but I doubt roots can take up air when exposed to the air, and probably dry out/die then). <br /> <br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

This system would not have that downside.<br /> <br /> Not sure how to do it, but possible by using a separate anaerobic digester and pretreating the effluent and perhaps diluting it too, before administering it into the hydroponic system. Methane production is unavoidable and a problem, so perhaps best to burn that and use the waste heat for heating up a greenhouse and using CO2 for injection to the greenhouse (for use by plants).<br /> <br /> See [https://www.ncbi.nlm.nih.gov/pubmed/22437012 here] and [https://www.sciencedirect.com/science/article/abs/pii/S0304389406013951 here].<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 17:39, 28 March 2020 (UTC)<br /> <br /> ----<br /> I forget when it was (few years ago?) I was geeking out about aquaponics, and was hearing of various catastrophic feedback loops in aquaponic systems. Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart.<br /> <br /> One solution i came across was sensor and camera based monitoring (some even had internet viewing)<br /> <br /> OTS these were VERY expensive, but perhaps some sort of arduino device?<br /> <br /> Don't know if i made a page for it yet. I did make a page for a sort of lab venier probe logger type device, perhaps we can use that page?<br /> <br /> Either way would that be an option?<br /> <br /> <br /> '''SECONDLY'''<br /> <br /> On the whole modular approach of yours that seems good as well<br /> <br /> I was plotting some sort of biogas/syngas -> CNG upgrader + compressor system<br /> <br /> Supposedly water scrubbing works? so that seems SOMEWHAT simple<br /> <br /> Main problem is compressing a flammible gas to high pressure<br /> <br /> I know marcin had some sort of pvc pipe storage in the works, was that lower pressure<br /> <br /> ANYWAYS that seems like what the best way to send that off would be<br /> <br /> For the C02 enriching, that works great, perhaps either a low-NOx burner?<br /> <br /> I was trying to find direct methane fuel cells, as that would be wonderful, all seem very experimental as of now<br /> <br /> Another way would be to generate co2 in the "Central Burner" area (where the gassifier hydronic heater is) and have either a near pure (ie scrubbed, yet more complex) or concentrated plumbed CO2 line? More complex, but may lead to more co-generation in using the methane. Granted CHP for the greenhouse works great if the area is cold<br /> <br /> Also CO2 Sensors would be useful for the whole enriching thing to be able to control the precise levels<br /> <br /> Along the lines of effulent and nutrient mixes, how do we go about testing this (sensor wise, not plant growth wise), i know Dissolved Oxygen Sensors, PH sensors, temperature probes are easy, but nutrients etc, what would be needed<br /> <br /> I think making a modification of the IBC container WWT system could be used? (Slow sand filter?)<br /> <br /> '''I'm kind of rambling on here, but altogether:'''<br /> *Seems like a good idea, and valid concern of "ecosystem?" collapse<br /> *This would allow for additional modularity perhaps (Fish Module, Anerobic Digester Module, Effluent Processor Module, Nutrient Manifold Module, Greenhouse Monitor Module, etc)<br /> *Course of action post COVID-19 work perhaps would be:<br /> **Sensor "Brain Unit" and modular probes etc<br /> **Biogas->Methane Scrubber<br /> **More Waste Water Treatment, and Greywater/effulent water reuse tech etc<br /> **Nutrient "Recepies" and "dosing" devices<br /> <br /> I don't know if i got what you were trying to get across, so if i missed something feel free to clarify if need be.

Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-)<br /> <br /> ::So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite labourious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> ::For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> ::Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the gas untill someone comes alone and burns it with an oil burner or something). The only thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

I would like to know what the most important item is that is not already being worked on by someone else.

Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two.

Some responses:<br /> <br /> " Main one I heard about was overheating of the water, which then lead to lower dissolved oxygen and everything fell apart. One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-)<br /> <br /> So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite laborious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the gas untill someone comes alone and burns it with an oil burner or something). The only thing you really need to examine closely (and probably test in practice) is the effluent treatment device (because if you don't get this right, it can't compete with regular hydroponics systems which use regular nutrient fluid.<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

I made a 'first draft' of a design for the [[Well-drilling Rig]] and would like to work on either a preliminary design for another of the machines or make drawings of something like the tractor bucket or backhoe, etc. I want to work on something else in the next few days to weeks so that the community has time to comment on the well-drilling rig and after that time I can go back and make any revisions to that that the community comes up with. I would like to know what the most important item is that is not already being worked on by someone else. I had read that someone is working on CAD files for the tractor and that the torch table is cutting some of the pieces for it so that sounds like it is covered, does the liberator have CAD drawings, or are there things that need formal CAD drawings (rather than just blender mockups). -[[User:Andrew Buck|Andrew Buck]] 08:44, 18 May 2011 (PDT)<br /> <br /> <br /> :Andrew - i added you to the CAD team. We have a number of people - and after the production run, we aim to leverage all this assistance to generate CAD for about 20 other devices - in which we'll need all the help we can get. We plan on then prototyping Sep 1-30 in the Factor e Farm Convergence (to be blogged). Spread the word on the forums, and let's keep building our CAD team - Marcin<br /> <br /> :: I will do the survey and add myself to the relevant CAD team (thank you for pointing me to the CAD team by the way, I hadn't found it on the help pages). I would like to know what to be working on right now though. Of the 20 devices you plan to build in the next phase I would assume very few, if any have formal drawings made. Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two. The well drilling rig uses some of both systems as I wasn't sure what you typically worked with but if I know the preferred system it is easier to do that right from the get go. -[[User:Andrew Buck|Andrew Buck]] 09:14, 18 May 2011 (PDT)<br /> <br /> :: I have added renderings of a couple of the models I finished so far. I have models for the [[Universal Rotor]] and the [[Backhoe]]. I have added a PNG version of a 2d sketch of the rotor (the wiki won't let me upload SVG files), if you or someone else on the farm there could add dimensions to it as indicated in the note that would be cool. The dimensions it has now should be reasonably close to the one you have there but it would be nice to have an accurate model for discussion of changes to be made before the next prototype. I plan to keep modeling, but am running out of ideas of things to work on until I do the second drafts of these models, any suggestions on where to go next would be appreciated. -[[User:Andrew Buck|Andrew Buck]] 22:09, 19 May 2011 (PDT)<br /> --<br /> <br /> == Wikinames/solid GVCS list ==<br /> <br /> Hi Marcin, can you please confirm the [[Wikinames | list]] here to ensure that all 50 machines are accounted for?

One solution i came across was sensor and camera based monitoring (some even had internet viewing)"<br /> :: I think the weak point are the fish really. First of all, they're very sensitive to the water (too much of a nutrient and they may die, too little oxygen and they die -the oxygen amounts indeed depend on water temperature-)<br /> <br /> So the main benefit is that with this system, you actually don't need to use any fish eliminating a major weakness of the aquaponics system.<br /> Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite laborious, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components). <br /> <br /> For CO2 enriching: I was thinking of just piping the entire combustion gas (gas from burnt methane/biogas from the digester) into the greenhouse when no persons are in it (the windows of the greenhouse are opened now and then, so that can occur before any persons enter the greenhouse -harvest season, nurturing, ...- . The burner can also stand in the greenhouse so the waste heat just gets spread into it.<br /> <br /> Discard as much automation as possible, effluent can be added to hydroponics system manually.<br /> You don't need to generate power from the methane, so no fuel cells or even combined heat and power systems. No compressor needed either. The power for running the water pump can come from a pv panel or grid power (corded). For burning the biogas/methane, I was thinking of just a valve and a pilot flame. Could perhaps be done manually too (so just store the gas)<br /> [[User:OS combined cycle|OS combined cycle]] ([[User talk:OS combined cycle|talk]]) 08:21, 2 April 2020 (UTC)</div>

I made a 'first draft' of a design for the [[Well-drilling Rig]] and would like to work on either a preliminary design for another of the machines or make drawings of something like the tractor bucket or backhoe, etc. I want to work on something else in the next few days to weeks so that the community has time to comment on the well-drilling rig and after that time I can go back and make any revisions to that that the community comes up with. I would like to know what the most important item is that is not already being worked on by someone else. I had read that someone is working on CAD files for the tractor and that the torch table is cutting some of the pieces for it so that sounds like it is covered, does the liberator have CAD drawings, or are there things that need formal CAD drawings (rather than just blender mockups). -[[User:Andrew Buck|Andrew Buck]] 08:44, 18 May 2011 (PDT)<br /> <br /> <br /> :Andrew - i added you to the CAD team. We have a number of people - and after the production run, we aim to leverage all this assistance to generate CAD for about 20 other devices - in which we'll need all the help we can get. We plan on then prototyping Sep 1-30 in the Factor e Farm Convergence (to be blogged). Spread the word on the forums, and let's keep building our CAD team - Marcin<br /> <br /> :: I will do the survey and add myself to the relevant CAD team (thank you for pointing me to the CAD team by the way, I hadn't found it on the help pages). I would like to know what to be working on right now though. Of the 20 devices you plan to build in the next phase I would assume very few, if any have formal drawings made. Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two. The well drilling rig uses some of both systems as I wasn't sure what you typically worked with but if I know the preferred system it is easier to do that right from the get go. -[[User:Andrew Buck|Andrew Buck]] 09:14, 18 May 2011 (PDT)<br /> <br /> :: I have added renderings of a couple of the models I finished so far.

I have added a PNG version of a 2d sketch of the rotor (the wiki won't let me upload SVG files), if you or someone else on the farm there could add dimensions to it as indicated in the note that would be cool. The dimensions it has now should be reasonably close to the one you have there but it would be nice to have an accurate model for discussion of changes to be made before the next prototype.

<p>OS combined cycle: </p> <hr /> <div>'''Vertical farming''' refers to growing crops in vertically stacked layers (thus being able to grow more plants on a same space).<br /> It can use simply containers with soil, [[hydroponics]], [[aquaponics]], [[aeroponics]], ...<br /> <br /> ==Containers with soil==<br /> Containers with soil allow plants to get their nutrients from the soil itself, thus not requiring (expensive) nutrient fluid.<br /> The soil can be replaced every year (or sooner) with other soil with more nutrients (for example obtained from a compost pile). Easiest to do this is with gutters (perforated pipes are more difficult for this).<br /> <br /> Some often used (low cost) techniques include using pallets and cloth (to make pockets on the pallet to plant in), or (plastic or aluminum) gutters or perforated plastic pipes. Gutters can be placed on an A-frame (which can be made from timber, or wooden or aluminum [[gridbeam]] or thick bamboo). See some example here:<br /> * [https://www.youtube.com/watch?v=D8qfd3LOIgQ A frame using gutters]<br /> <br /> A simple A-frame can hold up to 12 gutters or perforated pipes:<br /> * [https://project.theownerbuildernetwork.co/2017/02/10/build-an-efficient-a-frame-hydroponic-system/ A frame hydroponic system using 12 perforated pipes]<br /> <br /> Whatever the material is used for the gutters or pipes, all pipe/gutters can be placed on a slight elevation to allow excess water to flow out.<br /> All of them can either be fitted with a drain pipe to drop the water straight into a container and the container can be fitted with a simple aquarium pump to pump excess water from that container back into pipes/gutters, thus recycling the water (and some nutrients) and reducing the water requirements. The pump can use a time switch and the duration of continuous watering can be set per day (thus making sure the soil isn't overwatered, which would cause plant roots to rot).<br /> <br /> If using plastic pipes or gutters (which may be the easiest to acquire and relatively inexpensive), you could use a geotextile cloth in the pipe to further reduce the chance of pollutants from the plastic to leach through into the plant itself (via the soil or water).</div>

OS combined cycle https://wiki.opensourceecology.org/index.php?title=Gridbeam&diff=213507 Gridbeam 2020-03-14T17:21:02Z

<p>OS combined cycle: /* OSE pages */</p> <hr /> <div>=Introduction=<br /> *Originally titled''The Box Beam Sourcebook'' by Jorgensen<br /> <br /> =Gridbeam for Vehicles=<br /> Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14, 13 or 12 gauge (0,21 mm - 0,24 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,3 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, ABS plastic, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, (pillow block) (axle) rings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed. Sometimes, there are no gears but a 12V/24V selector is present, allowing to speed up the vehicle when needed. Most also don't have a regular differential; instead live split axles or transaxles are used. Suspension is also present, often in the form of trailer torsion axles or suspension forks.<br /> <br /> When making adapters yourself, use steel plates with a thickness between 1/8 inch and 1/4 inch (0,32 mm - 0,63 mm ). Use a drill in a drill press vise for accurate drilling.<br /> <br /> =Versions=<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 25-35% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, popular hole sizes are 11/32 inch, and 7/16 inch and popular bolt sizes are 5/16 inch and 3/8 inch. For the metric gridbeam, we can use a 6 mm bolt and 7-8 mm holes for the 25 mm gridbeam; a 9 mm bolt and 10-11 mm holes for the 40 mm gridbeam and 12 mm bolt and 13-14 mm holes for the 50 mm gridbeam. Use the 8,11 and 14 mm holes for wooden gridbeams, and the 7, 10 and 13 mm holes for metal gridbeams. Bolt sizes (6, 9 and 12 mm) are the same for both wooden and metal metric gridbeams. Reasons for this are that we can then reduce the number of different bolts sizes, and still use the smallest bolt with the largest hole (important for projects that use multiple gridbeam sizes). When buying imperial gridbeams and cutting them to metric sizes, also increase the hole size to metric where needed, and when the imperial beams have larger holes than in the metric version, simply keep the hole size but use metric bolts in them.<br /> <br /> =Designs=<br /> ==Furniture==<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ==Vehicles==<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, Willits High School Electrathon Racer, Star Lite, Soltrain, Rail Rocket,...<br /> <br /> ==PV mounts==<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide.

I made a 'first draft' of a design for the [[Well-drilling Rig]] and would like to work on either a preliminary design for another of the machines or make drawings of something like the tractor bucket or backhoe, etc. I want to work on something else in the next few days to weeks so that the community has time to comment on the well-drilling rig and after that time I can go back and make any revisions to that that the community comes up with. I would like to know what the most important item is that is not already being worked on by someone else. I had read that someone is working on CAD files for the tractor and that the torch table is cutting some of the pieces for it so that sounds like it is covered, does the liberator have CAD drawings, or are there things that need formal CAD drawings (rather than just blender mockups). -[[User:Andrew Buck|Andrew Buck]] 08:44, 18 May 2011 (PDT)<br /> <br /> <br /> :Andrew - i added you to the CAD team. We have a number of people - and after the production run, we aim to leverage all this assistance to generate CAD for about 20 other devices - in which we'll need all the help we can get. We plan on then prototyping Sep 1-30 in the Factor e Farm Convergence (to be blogged). Spread the word on the forums, and let's keep building our CAD team - Marcin<br /> <br /> :: I will do the survey and add myself to the relevant CAD team (thank you for pointing me to the CAD team by the way, I hadn't found it on the help pages). I would like to know what to be working on right now though. Of the 20 devices you plan to build in the next phase I would assume very few, if any have formal drawings made. Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two. The well drilling rig uses some of both systems as I wasn't sure what you typically worked with but if I know the preferred system it is easier to do that right from the get go. -[[User:Andrew Buck|Andrew Buck]] 09:14, 18 May 2011 (PDT)<br /> <br /> :: I have added renderings of a couple of the models I finished so far. I have models for the [[Universal Rotor]] and the [[Backhoe]]. I have added a PNG version of a 2d sketch of the rotor (the wiki won't let me upload SVG files), if you or someone else on the farm there could add dimensions to it as indicated in the note that would be cool. The dimensions it has now should be reasonably close to the one you have there but it would be nice to have an accurate model for discussion of changes to be made before the next prototype. I plan to keep modeling, but am running out of ideas of things to work on until I do the second drafts of these models, any suggestions on where to go next would be appreciated. -[[User:Andrew Buck|Andrew Buck]] 22:09, 19 May 2011 (PDT)<br /> --<br /> <br /> == Wikinames/solid GVCS list ==<br /> <br /> Hi Marcin, can you please confirm the [[Wikinames | list]] here to ensure that all 50 machines are accounted for?

I made a 'first draft' of a design for the [[Well-drilling Rig]] and would like to work on either a preliminary design for another of the machines or make drawings of something like the tractor bucket or backhoe, etc. I want to work on something else in the next few days to weeks so that the community has time to comment on the well-drilling rig and after that time I can go back and make any revisions to that that the community comes up with. I would like to know what the most important item is that is not already being worked on by someone else. I had read that someone is working on CAD files for the tractor and that the torch table is cutting some of the pieces for it so that sounds like it is covered, does the liberator have CAD drawings, or are there things that need formal CAD drawings (rather than just blender mockups). -[[User:Andrew Buck|Andrew Buck]] 08:44, 18 May 2011 (PDT)<br /> <br /> <br /> :Andrew - i added you to the CAD team. We have a number of people - and after the production run, we aim to leverage all this assistance to generate CAD for about 20 other devices - in which we'll need all the help we can get. We plan on then prototyping Sep 1-30 in the Factor e Farm Convergence (to be blogged). Spread the word on the forums, and let's keep building our CAD team - Marcin<br /> <br /> :: I will do the survey and add myself to the relevant CAD team (thank you for pointing me to the CAD team by the way, I hadn't found it on the help pages). I would like to know what to be working on right now though. Of the 20 devices you plan to build in the next phase I would assume very few, if any have formal drawings made. Is there a place where the list is up that I can see what the 20 machines are, and are there some that you and the others on the farm think are particularly important to the next phase. I plan on doing this full time for the next few weeks and if I have to spend 3 days waiting around on forum replies, etc, it is 3 days I can't do anything productive. I plan to do the loader bucket, universal rotor (which I will try to make work with my well drilling rig), and the backhoe. If these sound good that's what I will do, but if there is something else needed for the next phase I would focus on that instead. Also, do you work in standard inches feet, etc in the shop or do you use meters, cm etc, or a mix of the two. The well drilling rig uses some of both systems as I wasn't sure what you typically worked with but if I know the preferred system it is easier to do that right from the get go. -[[User:Andrew Buck|Andrew Buck]] 09:14, 18 May 2011 (PDT)<br /> <br /> :: I have added renderings of a couple of the models I finished so far. I have models for the [[Universal Rotor]] and the [[Backhoe]]. I have added a PNG version of a 2d sketch of the rotor (the wiki won't let me upload SVG files), if you or someone else on the farm there could add dimensions to it as indicated in the note that would be cool. The dimensions it has now should be reasonably close to the one you have there but it would be nice to have an accurate model for discussion of changes to be made before the next prototype. I plan to keep modeling, but am running out of ideas of things to work on until I do the second drafts of these models, any suggestions on where to go next would be appreciated. -[[User:Andrew Buck|Andrew Buck]] 22:09, 19 May 2011 (PDT)<br /> --<br /> <br /> == Wikinames/solid GVCS list ==<br /> <br /> Hi Marcin, can you please confirm the [[Wikinames | list]] here to ensure that all 50 machines are accounted for?

OS combined cycle https://wiki.opensourceecology.org/index.php?title=Gridbeam&diff=182214 Gridbeam 2018-11-28T10:32:13Z

<p>OS combined cycle: /* Links */</p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14, 13 or 12 gauge (0,21 mm - 0,24 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,3 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, ABS plastic, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, (pillow block) (axle) rings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed. Sometimes, there are no gears but a 12V/24V selector is present, allowing to speed up the vehicle when needed. Most also don't have a regular differential; instead live split axles or transaxles are used. Suspension is also present, often in the form of trailer torsion axles or suspension forks.<br /> <br /> When making adapters yourself, use steel plates with a thickness between 1/8 inch and 1/4 inch (0,32 mm - 0,63 mm ). Use a drill in a drill press vise for accurate drilling.<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 25-35% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, popular hole sizes are 11/32 inch, and 7/16 inch and popular bolt sizes are 5/16 inch and 3/8 inch. For the metric gridbeam, we can use a 6 mm bolt and 7-8 mm holes for the 25 mm gridbeam; a 9 mm bolt and 10-11 mm holes for the 40 mm gridbeam and 12 mm bolt and 13-14 mm holes for the 50 mm gridbeam. Use the 8,11 and 14 mm holes for wooden gridbeams, and the 7, 10 and 13 mm holes for metal gridbeams. Bolt sizes (6, 9 and 12 mm) are the same for both wooden and metal metric gridbeams. Reasons for this are that we can then reduce the number of different bolts sizes, and still use the smallest bolt with the largest hole (important for projects that use multiple gridbeam sizes). When buying imperial gridbeams and cutting them to metric sizes, also increase the hole size to metric where needed, and when the imperial beams have larger holes than in the metric version, simply keep the hole size but use metric bolts in them. <br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, Willits High School Electrathon Racer, Star Lite, Soltrain, Rail Rocket,...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide.

<p>OS combined cycle: </p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14, 13 or 12 gauge (0,21 mm - 0,24 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,3 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, ABS plastic, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, (pillow block) (axle) rings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed. Sometimes, there are no gears but a 12V/24V selector is present, allowing to speed up the vehicle when needed. Most also don't have a regular differential; instead live split axles or transaxles are used. Suspension is also present, often in the form of trailer torsion axles or suspension forks.<br /> <br /> When making adapters yourself, use steel plates with a thickness between 1/8 inch and 1/4 inch (0,32 mm - 0,63 mm ). Use a drill in a drill press vise for accurate drilling.<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 25-35% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, popular hole sizes are 11/32 inch, and 7/16 inch and popular bolt sizes are 5/16 inch and 3/8 inch. For the metric gridbeam, we can use a 6 mm bolt and 7-8 mm holes for the 25 mm gridbeam; a 9 mm bolt and 10-11 mm holes for the 40 mm gridbeam and 12 mm bolt and 13-14 mm holes for the 50 mm gridbeam. Use the 8,11 and 14 mm holes for wooden gridbeams, and the 7, 10 and 13 mm holes for metal gridbeams. Bolt sizes (6, 9 and 12 mm) are the same for both wooden and metal metric gridbeams. Reasons for this are that we can then reduce the number of different bolts sizes, and still use the smallest bolt with the largest hole (important for projects that use multiple gridbeam sizes). When buying imperial gridbeams and cutting them to metric sizes, also increase the hole size to metric where needed, and when the imperial beams have larger holes than in the metric version, simply keep the hole size but use metric bolts in them. <br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, Willits High School Electrathon Racer, Star Lite, Soltrain, Rail Rocket,...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide. The panel can then be rotated by a stepper motor by putting it on a plywood supported by an axle.

<p>OS combined cycle: /* Links */</p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14 tot 12 gauge (0,21 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,12 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, ABS plastic, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, (pillow block) (axle) rings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed. Sometimes, there are no gears but a 12V/24V selector is present, allowing to speed up the vehicle when needed. Most also don't have a regular differential; instead live split axles or transaxles are used. Suspension is also present, often in the form of trailer torsion axles or suspension forks.<br /> <br /> When making adapters yourself, use steel plates with a thickness between 1/8 inch and 1/4 inch (0,32 mm - 0,63 mm ). Use a drill in a drill press vise for accurate drilling.<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 25-35% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, a popular hole size is 11/32 inch, and popular bolt sizes are 5/16 inch and 1/4 inch. For the metric gridbeam, we can use a 6 mm bolt and 7-8 mm holes for the 25 mm gridbeam; a 9 mm bolt and 10-11 mm holes for the 40 mm gridbeam and 12 mm bolt and 13-14 mm holes for the 50 mm gridbeam. Use the 8,11 and 14 mm holes for wooden gridbeams, and the 7, 10 and 13 mm holes for metal gridbeams. Bolt sizes (6, 9 and 12 mm) are the same for both wooden and metal metric gridbeams. Reasons for this are that we can then reduce the number of different bolts sizes, and still use the smallest bolt with the largest hole (important for projects that use multiple gridbeam sizes). When buying imperial gridbeams and cutting them to metric sizes, also increase the hole size to metric where needed, and when the imperial beams have larger holes than in the metric version, simply keep the hole size but use metric bolts in them. <br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, Willits High School Electrathon Racer, Star Lite, Soltrain, Rail Rocket,...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide. The panel can then be rotated by a stepper motor by putting it on a plywood supported by an axle. The axle needs to be at least 78 inch long (75" for the panel + 1,5" + 1,5" for the beams + space to mount the electric motor).

<p>OS combined cycle: /* Vehicles */</p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14 tot 12 gauge (0,21 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,12 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed. Sometimes, there are no gears but a 12V/24V selector is present, allowing to speed up the vehicle when needed. Most also don't have a regular differential; instead live split axles or transaxles are used. Suspension is also present, often in the form of trailer torsion axles or suspension forks.<br /> <br /> When making adapters yourself, use steel plates with a thickness between 1/8 inch and 1/4 inch (0,32 mm - 0,63 mm ). Use a drill in a drill press vise for accurate drilling.<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 30% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, a popular hole size is 11/32 inch, and popular bolt sizes are 5/16 inch and 1/4 inch. For the metric gridbeam, we can use an 8 mm hole and a 6,5 mm bolt for the 25 mm gridbeam; a 12 mm hole and an 11 mm bolt for the 40 mm gridbeam and a 15 mm hole and a 14 mm bolt for the 50 mm gridbeam.<br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, Willits High School Electrathon Racer, Star Lite, Soltrain, Rail Rocket,...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide. The panel can then be rotated by a stepper motor by putting it on a plywood supported by an axle. The axle needs to be at least 78 inch long (75" for the panel + 1,5" + 1,5" for the beams + space to mount the electric motor). By making it this way, the whole has a limited height, which reduces the possibility of damage by wind.<br /> <br /> ===OSE designs===<br /> ==== LifeTrac ====<br /> [[Image:Warehouse_for_LifeTrac.jpeg|thumb|right|140px|grid-beam-like components before they are assembled into a LifeTrac]]<br /> [[Image:Tractor Build 218.JPG|thumb|right|140px|LifeTrac 5 under construction]]<br /> : ''main article: [[LifeTrac]]''<br /> <br /> The basic frame of the LifeTrac is bolted together from 4x4x1/4" square tubing,<br /> in an arrangement very similar to the "grid beam" techniques.<br /> <br /> ==OSE pages==<br /> * [[Eric Hunting Resource Guide#Matrix.2FBox Beam.2FGrid Beam|Eric Hunting Resource Guide]]<br /> <br /> ==Links==<br /> * [http://gridbeam.com/ gridbeam.com; official website]<br /> * [http://gridbeamers.com/ gridbeamers.com, defunct]<br /> * [http://synergyii.com/Quikstix/index.html Quikstix page (gridbeam company of the jergensons)]<br /> * [https://8020.net/university-readytube 80/20 Inc Ready Tube], [https://www.mcmaster.com/Standard-Bolt-Together-Structural-Framing McMaster-Carr Bolt-Together Framing], [http://www.atc-mechanical.com/telespar/square-sign-post/ Allied Tube Telespar and Quick-Punch], [http://www.atc-mechanical.com/mechanical-tubing/square-fit-steel-tubing/ Allied Tube Square-Fit], [http://www.s-squaretube.com/Products/ProductDetails/tabid/85/ProductID/13/Default.aspx S-Square Square Post Perforated], [http://www.unistrut.us/DB/PDF1/Uni_Telespar.pdf Unistrut Telespar], Ultimate Highway Products Ulti-Mate steel highway sign posts: gridbeam-like products<br /> * [http://www.unistrut.us/index.php?WP=cat_detail&S=S03&P=P9000 Unistrut Telestrut]: gridbeam-like but with a different hole spacing so incompatible<br /> * [http://www.exercise-desk.com exercise-desk.com (defunct)]<br /> * [http://www.recliner-workstation.com recliner-workstation.com (defunct)]<br /> * [http://www.edburtoncompany.com/ edburtoncompany (defunct)]<br /> * [http://wiki.p2pfoundation.net/Grid_Beam gridbeam page at P2PF]<br /> * [http://gridbeam.biz/ gridbeam.biz (defunct)]<br /> * [http://www.gridbeamnation.com/ grid beam nation; defunct]<br /> * [http://www.gridbeamwiki.org/ gridbeamwikie; defunct]<br /> * [http://www.gridbeamsolutions.com The paper book], and [https://www.newsociety.com/Books/H/How-to-Build-With-Grid-Beam-PDF the e-book]<br /> * [https://secure.flickr.com/photos/nikolayhg1/sets/72157629932382005/ photos]<br /> <br /> [[Category: Open Hardware]]<br /> [[Category: Construction]]<br /> [[Category: Modular]]</div>

<p>OS combined cycle: </p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14 tot 12 gauge (0,21 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,12 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, lexan, or safety glass), accessories (bicycle wheels, garden tractor wheels, garden cart wheels, (pillow block) wheel bearings, angle plates/brackets, trailer torsion axles and wheels, live split axles and transaxles, sprockets, pulleys, ... ) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> Most gridbeam vehicles don't have a clutch; vehicles are stopped instead and the gear is changed.

<p>OS combined cycle: /* Vehicles */</p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). Wall thickness of the steel gridbeams is 14 tot 12 gauge (0,21 mm - 0,27 mm). Wall thickness of the aluminium gridbeams is 11 gauge (0,12 mm). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, lexan, or safety glass), accessories (bicycle wheels, (pillow block) wheel bearings, angle plates, mechanical parts) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 30% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, a popular hole size is 11/32 inch, and popular bolt sizes are 5/16 inch and 1/4 inch. For the metric gridbeam, we can use an 8 mm hole and a 6,5 mm bolt for the 25 mm gridbeam; a 12 mm hole and an 11 mm bolt for the 40 mm gridbeam and a 15 mm hole and a 14 mm bolt for the 50 mm gridbeam.<br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Panther Electric, ...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide.

The axle needs to be at least 78 inch long (75" for the panel + 1,5" + 1,5" for the beams + space to mount the electric motor).

<p>OS combined cycle: </p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). The gridbeam system also uses hardware (hex nuts and bolts, flat washers, carriage bolts, joint connector bolts and weld nuts, external tooth lock washers and flange/flex-type locknuts, castle nuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, lexan, or safety glass), accessories (bicycle wheels, (pillow block) wheel bearings, angle plates, mechanical parts) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Castle nuts are used to fasten axles. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts.<br /> <br /> All hardware should be stainless steel, grade 1 hardness or more, with nuts having equal hardness level as the bolts, bolt lengths being equal to the beam thickness x2 (for allowing them to go through 2 beams). <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 30% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, a popular hole size is 11/32 inch, and popular bolt sizes are 5/16 inch and 1/4 inch. For the metric gridbeam, we can use an 8 mm hole and a 6,5 mm bolt for the 25 mm gridbeam; a 12 mm hole and an 11 mm bolt for the 40 mm gridbeam and a 15 mm hole and a 14 mm bolt for the 50 mm gridbeam.<br /> <br /> ==Designs==<br /> ===Furniture===<br /> A wide range of furniture (such as desks, beds, tables, chairs, lcd monitor stands, ...) have been designed.<br /> <br /> ===Vehicles===<br /> Several electric vehicles have been designed with gridbeam.<br /> Examples are the Electric Vehicle Test Bed, Solar Powered Utility Vehicle, Scamp, Electric Tote Goat, Japanese Bear, X-wing, Vanda, Electric Moose, ...<br /> <br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide.

By making it this way, the whole has a limited height, which reduces the possibility of damage by wind.<br /> <br /> ===OSE designs===<br /> ==== LifeTrac ====<br /> [[Image:Warehouse_for_LifeTrac.jpeg|thumb|right|140px|grid-beam-like components before they are assembled into a LifeTrac]]<br /> [[Image:Tractor Build 218.JPG|thumb|right|140px|LifeTrac 5 under construction]]<br /> : ''main article: [[LifeTrac]]''<br /> <br /> The basic frame of the LifeTrac is bolted together from 4x4x1/4" square tubing,<br /> in an arrangement very similar to the "grid beam" techniques.<br /> <br /> ==OSE pages==<br /> * [[Eric Hunting Resource Guide#Matrix.2FBox Beam.2FGrid Beam|Eric Hunting Resource Guide]]<br /> <br /> ==Links==<br /> * [http://gridbeam.com/ gridbeam.com; official website]<br /> * [http://gridbeamers.com/ gridbeamers.com, defunct]<br /> * [http://synergyii.com/Quikstix/index.html Quikstix page (gridbeam company of the jergensons)]<br /> * [https://8020.net/university-readytube 80/20 Inc Ready Tube], [https://www.mcmaster.com/Standard-Bolt-Together-Structural-Framing McMaster-Carr Bolt-Together Framing], [http://www.atc-mechanical.com/telespar/square-sign-post/ Allied Tube Telespar]: gridbeam-like products<br /> * [http://www.unistrut.us/index.php?WP=cat_detail&S=S03&P=P9000 Unistrut Telestrut]: gridbeam-like but with a different hole spacing so incompatible<br /> * [http://www.exercise-desk.com exercise-desk.com (defunct)]<br /> * [http://www.recliner-workstation.com recliner-workstation.com (defunct)]<br /> * [http://wiki.p2pfoundation.net/Grid_Beam gridbeam page at P2PF]<br /> * [http://gridbeam.biz/ gridbeam.biz (defunct)]<br /> * [http://www.gridbeamnation.com/ grid beam nation; defunct]<br /> * [http://www.gridbeamwiki.org/ gridbeamwikie; defunct]<br /> * [http://www.gridbeamsolutions.com The paper book], and [https://www.newsociety.com/Books/H/How-to-Build-With-Grid-Beam-PDF the e-book]<br /> * [https://secure.flickr.com/photos/nikolayhg1/sets/72157629932382005/ photos]<br /> <br /> [[Category: Open Hardware]]<br /> [[Category: Construction]]<br /> [[Category: Modular]]</div>

<p>OS combined cycle: </p> <hr /> <div>Grid beam is a simple [[modular construction]] technique. The core technology of this system is the beam, which has holes in it along its entire length, on all 4 sides. As well as holes, it is also able to create tri-joints, which are connections between 3 beams in which each beam is secured with 2 bolts. Gridbeams (in wood, galvanised steel and aluminium) are available for purchase from stores, and can be made yourself using standard industry components (lumber or metal pipes cut to the sizes described on this page). The gridbeam system also uses hardware (hex nuts and bolts, washers, carriage bolts, joint connector bolts and weld nuts, lock washers and locknuts, thread-locking fluid), panels (in same sizes as the gridbeams, in plywood, signboard, hardboard, sheet metal, fibreglass, plexiglass, lexan, or safety glass), accessories (wheels, mechanical parts) and adapters (custom-made metal components that make non-compatible accessories fit unto gridbeam).<br /> <br /> Hex nuts and bolts are used with most metal gridbeams as they are the strongest. Lockwashers, locknuts and thread-locking fluid is used for vehicle projects. Joint connector bolts and weldnuts and carriage bolts are useful for when panelling needs to be attached to gridbeams because they are much flatter than regular hex bolts and nuts. <br /> <br /> Plexiglass and lexan are used for view ports and windows, and for windshields safety glass is used. Fibreglass and plexiglass are used for vehicle body panels. Sheet metal is used for decks in vehicles, ...<br /> <br /> ==Versions==<br /> Grid beam is a system of beams in which the width of each beam is equal to the hole spacing.<br /> The holes are always placed in the middle of the beam width, and the hole spacing refers to the space between the holes in the other direction.<br /> In the imperial system, beam width can be 1 inch, 1,5 inch and 2 inch. Hole spacing is similar (1 inch, 1,5 inch and 2 inch).<br /> In the metric system, beam width can be set to 25 mm (which is almost identical to 1 inch as 1 inch = 25,4 mm), 40 mm (almost identical to 1,5 inch as this is 38 mm), and 50 mm (almost identical as 2 inch is 50,8 mm). Hole spacing follows accordingly.<br /> Lengths of the beams need to be multiples of the beam width. In the imperial version, the lengths are per foot and per half foot, in the metric system it can be done per meter, per 1/2 meter and per 1/5 meter).<br /> The hole diameter needs to be about 30% of the beam width, and the bolts need to be 1 mm smaller than the holes for metal gridbeams and 2 mm smaller than the hole for wooden gridbeams. In the imperial version, a popular hole size is 11/32 inch, and popular bolt sizes are 5/16 inch and 1/4 inch. For the metric gridbeam, we can use an 8 mm hole and a 6,5 mm bolt for the 25 mm gridbeam; a 12 mm hole and an 11 mm bolt for the 40 mm gridbeam and a 15 mm hole and a 14 mm bolt for the 50 mm gridbeam.<br /> <br /> ==Designs==<br /> ===PV mounts===<br /> A simple PV panel stand (for 65" x 39" and 75" x 39" PV panels) that can rotate along the horizontal plane (single-axis) can be made using [[Modular_construction|gridbeam]]. <br /> <br /> When using imperial gridbeam, it can be made 24 inch (=2 foot) high, 42 inch (=3,5 foot) long and 78 inch (=6,5 foot) wide. The panel can then be rotated by a stepper motor by putting it on a plywood supported by an axle. The axle needs to be at least 78 inch long (75" for the panel + 1,5" + 1,5" for the beams + space to mount the electric motor). By making it this way, the whole has a limited height, which reduces the possibility of damage by wind.<br /> <br /> ===OSE designs===<br /> ==== LifeTrac ====<br /> [[Image:Warehouse_for_LifeTrac.jpeg|thumb|right|140px|grid-beam-like components before they are assembled into a LifeTrac]]<br /> [[Image:Tractor Build 218.JPG|thumb|right|140px|LifeTrac 5 under construction]]<br /> : ''main article: [[LifeTrac]]''<br /> <br /> The basic frame of the LifeTrac is bolted together from 4x4x1/4" square tubing,<br /> in an arrangement very similar to the "grid beam" techniques.<br /> <br /> ==OSE pages==<br /> * [[Eric Hunting Resource Guide#Matrix.2FBox Beam.2FGrid Beam|Eric Hunting Resource Guide]]<br /> <br /> ==Links==<br /> * [http://gridbeam.com/ gridbeam.com; official website]<br /> * [http://gridbeamers.com/ gridbeamers.com, defunct]<br /> * [http://synergyii.com/Quikstix/index.html Quikstix page (gridbeam company of the jergensons)]<br /> * [https://8020.net/university-readytube 80/20 Inc Ready Tube], [https://www.mcmaster.com/Standard-Bolt-Together-Structural-Framing McMaster-Carr Bolt-Together Framing], [http://www.atc-mechanical.com/telespar/square-sign-post/ Allied Tube Telespar]: gridbeam-like products<br /> * [http://www.unistrut.us/index.php?WP=cat_detail&S=S03&P=P9000 Unistrut Telestrut]: gridbeam-like but with a different hole spacing so incompatible<br /> * [http://www.exercise-desk.com exercise-desk.com (defunct)]<br /> * [http://www.recliner-workstation.com recliner-workstation.com (defunct)]<br /> * [http://wiki.p2pfoundation.net/Grid_Beam gridbeam page at P2PF]<br /> * [http://gridbeam.biz/ gridbeam.biz (defunct)]<br /> * [http://www.gridbeamnation.com/ grid beam nation; defunct]<br /> * [http://www.gridbeamwiki.org/ gridbeamwikie; defunct]<br /> * [http://www.gridbeamsolutions.com The paper book], and [https://www.newsociety.com/Books/H/How-to-Build-With-Grid-Beam-PDF the e-book]<br /> * [https://secure.flickr.com/photos/nikolayhg1/sets/72157629932382005/ photos]<br /> <br /> [[Category: Open Hardware]]<br /> [[Category: Construction]]<br /> [[Category: Modular]]</div>
