Feel free to discuss your ideas and experiences regarding replication on the GVCS Replication category of our forum.
Using the Civilization Starter Kit, people are beginning to independently build their own Global Village Construction Set machinery throughout the world. Many of them have come to Factor e Farm for Dedicated Project Visits, and others have taught themselves based on our training materials. We conduct program evaluations.
If you have built any of the GVCS machines, we'd like to hear about your experience for learning purposes. Plaese fill out this form:

Daniel & Hayden: Pasadena, California, USA
We, along with our engineering class and several students from nearby Blair High School, intend to build a Lifetrac from the plans of Open Source Ecology. We will donate the tractor to The South Central Farmers Cooperative, for use on their 120 acre farm in Shafter, CA.
Our rationale for taking on this project is three pronged. By being among the first- and the first high school aged students- to replicate the Lifetrac, we are doing a service to the Open Ecology Project, and, consequently, may be helping change the future of agriculture everywhere. Our project will, likewise, benefit the South Central Farmers, who are eager to experiment with open source agricultural technology. Finally, bringing a project like this to the Polytechnic School (and, in a smaller degree to Blair High School) will provide aspiring engineers with a chance to use their skills in the field before leaving for college.
Manuel Aguilar: Guatemala
Manuel was co-founder of Quetsol. Quetsol offers appropriate technology solutions that sustainably provide for the energy demands of a wide variety of users at a lower social and economic cost.
Our project, currently in late planning stages, is building a sustainable village for about 30 families recently displaced by extreme weather in Guatemala. The village model will approach sustainability in an integral way, from housing design and construction to agriculture and resource management. Residences, for example, will incorporate appropriate materials (CEB mostly), passive solar design, and come standard with rain-catchment systems with prefiltration, mini greenhouses, efficient wood/methane stoves, water filtration, PV for light/comm, compost toilets, water recycling. Agri and aquaculture will be efficiently designed as well as per local conditions (location TBD soon). The aim will be to demonstrate a working prototype of a self-sustainable community built for the BOP, which can, when designed and built appropriately, economically replace the current minimum denominator settlements which cause so much human and environmental hazard. Ultimately we intend to build something replicable and scalable, which is where OSE comes in.
OSE will integrate into our work in a variety of ways. Initially, we aim to train a skilled replicator so that some of the first GVCS machines can be built on site and facilitate village construction and development. We also plan to build and equip a workshop in which to build the initial machines and which will also eventually serve as a high-value business opportunity to some trained villager entrepreneurs. Beyond the machines built for village use, which will generate value at reduced cost - income will be generated initially from fabricating machines for local distribution. Eventually, they workshop will also expand to include training of locals, so that other such businesses may sprout in other communities. This is in keeping with the OSE ethos, and at the core of many of our intentions with our project. The village aims to demonstrate that post-scarcity abundance can be achieved, even with the lowest means found amongst the BoP, with appropriate use of technology. OSE provides a fantastic set of tools and methodologies that potentiate development precisely through intelligent open-source design and tech.
In terms of time frame, in the next month, we will have purchased land, identified a replicator, finished first project proposal and begin land work. April I will be travelling abroad for 3 weeks, so construction of the first living Unit will take place mid-May. During summer, June-Aug, we will build the workshop and at some point fabricate the CEB press after having the replicator receive proper training. After this is accomplised, we will build the residential units and have the families begin to move in, as they will also be helping build their own houses.

Andrew Spina: Baltimore, Maryland, USA
I'm building my own tractor because I want to understand it and be able to maintain it. It's also a project that will teach me many valuable skills. I've already learned a ton about machining and CAD.
Finally, I'm interested in joining the material economy at some time in my life. So far I've earned my living by working in the knowledge economy. I think really hard and get paid to do it. I'm employed as a programmer. It's a job I love, but constrains my life quite a lot-- I work 40hr a week and have to commute to my place of work. One day, I'd like to have a bit more control-- perhaps program as a hobby.
What do I mean by 'material economy' (a green wing article)? I mean that I take ingredients and make a product. The product is a tangible thing that solves a tangible problem like hunger, need for shelter, etc. This is important because the tangible problems are the ones that force the average person to take a 9 to 5. If I can provide fixes for these root human needs, I'll have high security (someone somewhere is hungry) and be encouraging smaller scale self sufficiency. The OSE folk argue (see Village Scale here) that a material economy of about 200 people is enough for comfortable modern living locally. That sounds like somewhere I'd want to live.
So what will I produce in the material economy? I mean really, what will my tractor produce? I don't have a firm plan, but my current thoughts are to produce pelletized biomass. With a few tools (Tractor, Hay Cutter, Hammer Mill, Pelletizer) and some land, I may be able to produce a renewable, carbon neutral (or even negative!) local fuel. I'm not yet clear on the economics-- how much land make how many pellets? How much labor for each acre of land? How much do pellets cost? Where would I sell them? But, I'm going to have a tractor regardless so if the economics don't work, I'll find a different plan.

"October, 2011 marks the first ever replication of a complete GVCS machine by an independent third party. This is a day of historical significance for the Global Village Construction Set. Congratulations to James Slade of Texas."
- Marcin Jakubowski, Nov. 14, 2011
James Slade is one of the co-founder's of Creation Flame in Cedar Creek, Texas. In partnership with Jason Smith, Creation Flame is the first to successfully replicate a CEB press and is now getting into the business of using and selling CEB blocks. In unison with Thad from Broken Sidewalk Farm, they are starting production of a LifeTrac, self replicating CNC Plasma table, and another Powercube. Also starting to build a few Roller Tables to help with the CEB's and steel work.

Dandelion Village: Bloomington, Indiana, USA
Zach Dwiel is a member of Dandelion Village, an ecovillage in the city limits of Bloomington, Indiana. They are in the process of building their first home using a CEB Press and Power Cube. Tom built our Power Cube. For the CEB Press, James Slade fabricated the steel parts, Zach designed and built the controller board and electronics, purchased the hydraulics and Dandelion Village assembled the machine.
Zach plans to build a two story house this year (2012) with the bricks from the CEB Press. More buildings are planned for next year, some of which may include bricks from the CEB Press, depending on how production goes on the first home. You can find updates on my blog: blog and my house design here on this wiki: Dwiel House
Tony Mensah, Mark Amo-Boateng, William Neal: Nanjing, China
In May, 2012, this group, originally from Ghana and Canada, set out in Nanjing to redesign the CEB press to metric specifications and build it with the help of some engineers at a factory in Ma'anshan, Anhui, China.
According to a report received on September 27th, there were some technical issues surrounding the later stages of assembly of the CEB press, particularly centred around the secondary cylinder and the soil shaker.
In June, 2013, the group was finally able to test the brick press - successfully (youtube link).
Charles Liptaak's Replication
We made a bunch of bricks and found some areas to improve:
- Every once in a while the drawer jumped off the rollers and jammed. This is probably due to the hydraulic cylinder not being perfectly in-line with the drawer and pushing it slightly sideways. To fix this we removed the rollers and added 8 bearings, 4 to hold it up and 4 to prevent it moving it sideways. Now it works much better. This will also simplify the construction of the drawer, which now can be made with flat bottom rails.
Once I fix the second and third problems below, I’ll send you images/video
- Could be missing something here, but I’m finding the magnet/sensor combination unreliable. – I had the machine working perfectly, but after just having it sit there for two months, the sensors failed to pick up the magnets. Maybe I need to build the hall effect sensors little differently and perhaps out of a different material, but even moving the magnets manually in front of the sensors produced intermittent results.
Have you experienced anything similar? Have you considered other types of sensors/ control mechanisms?
- Fried my Aurdrino board. Totally self-inflicted. Had some issues with the software recognizing the cylinder positions at startup, and to override things I wanted to have manual controls. The manual override worked and the cylinders moved into position ok, but the feedback loop killed the board. Have you figured out how to add manual override switches?
- Wrt your other email on the power cube, we added an adjustable pressure bypass valve to the pump. This way if a cylinder is bottomed/topped out, the engine can keep running without stressing the pump. The only issue is cosmetic – we didn’t have enough room to do this within the frame and the hose is on the outside of the cube. – photos to follow
Response by MJ
- Agreed, the roller guide mechanism is the weak point. We have not had the drawer slip off the rollers when they were adjusted properly with the roller raisers. After a few thousand bricks - the machine loosened up such that the rollers were no longer holding the drawer tight. The drawer slipped off the rails, so we tightened the roller raisers and the drawer did not slip. However - we see this as an issue to be addressed - and we did that in CEB Press Prototype IV with the new modular roller mechanism designed by Marshall Hilton. Since the roller guides were a weak point - we made the rollers modular and more robust for easy installation.
- We found the magnet/sernor set finicky as well. We have a new design in CEB Press Prototype IV. See CEB_Press#Electronics_-_CEB_Press_IV.
Response by Zach Dwiel
- I've got a CEB Press with the newest roller mechanism (I believe), and haven't had any trouble yet, but also haven't pressed too many bricks yet.
- I also just ordered parts to add a pressure relief valve, which should probably be standard.
- I would love to know what the new design is that is replacing the old magnet/sensor set (I couldn't find any information on that link you provided other than the new control board I designed.) I'm part way through a rewrite of the code, but would rather wait and work on a newer version if there are new ideas. I was planning on writing an initialization step that required some manual control to 'show' it where the boundaries are, but that will be for nothing if the actual sensors are flakey
