=january 2016=
 
did a sketchup drawing of Schellenberg's conveyor build and adapted the idea to a modular design. still some room for improvement.

=october 2015=
 
built another battery prototype. still having trouble storing a charge. looking at the voltage graph of the charge it looks like it is charging, but when i try to drain the battery it dies within seconds. im not sure, but im guessing that part of the chemical reaction is happening but not all. [[Nickel-Iron_Battery/Chemistry]]
 
next steps. going to mix graphite into the iron. going to try some different charging procedures.

notes:
*goal to use same chain links from other parts
**microtrac chain sections difficult to fit between mount structure and 3" pivot pin
 
made a sketchup model attempting to put chain around existing pivot pin. was only able to get a total 100 degree range of motion. to get full 180 degrees will have to extend the pivot pin above/above main mount, or make changes to structure.

started doing some work on tracks. i think using the style where each sequential track is inner then outer will simplify welding work. will it create problems for sprocket rolling into gap? pinch point?
 
i think the size of angle iron pads needs to be slightly smaller than pitch between rollers for space between
 
need to hunt some plugins or converter, cant export sprocket from openscad and import into sketchup

thought the bolt might need to be torched out but on second look i think its alright
 
=may 7, 2015=
 
*added some small rollers.
**might be tricky to keep from getting caught on linkage of treads
***perhaps find plastic/rubber wheels that would less likely catch
*might make front and back rollers larger diameter
**need more ground clearance
*might move rotor units apart 4 more inches
**longer track length to support more

had to order some more drill bits. some of the ones i got were super brittle and broke quick.
 
think im going to try to build up the portuguese wiki pages. will also use it as an opportunity to test some best practices ideas. i'd like to have a clear table for versions, change log, approx number built, link to file landing page.
 
:some examples i might incorporate

finished cleaning the holes of one side of one cage. i held it flat and poured water evenly over the holes. took about 6 seconds for it to drain through. continuing on.
 
=march 18, 2015=
Sign up for osemail on wiki. Will return to dozer gear down.-MJ
 
i used https://www.3dhubs.com/ to order some larger cages to compare and test out. [https://www.3dhubs.com/oklahoma-city/hubs/merrick  the local guy] that printed them had a very high quality print with ABS, much better than my prints. even with a better print it appears the design as-is requires to have a lot of holes cleaned out.
 
if battery proves viable, might attempt using a two material 3d print with dissolvable material in holes. or maybe hole design improvement is possible.
 
in the mean time, going to clear out holes manually and might test larger cages next week.
 
*design change
**might make the powder area smaller and leave upper part where lid inserts same size.
 
=march 14, 2015=
 
printed two larger cages. tested holes with some food coloring. put a few drops inside, filled sink with water up to top of cage, opened sink drain, able to see color come through holes that are open. it appears more than half of the holes are not open for water to flow through. going to try to get a small drill bit to quickly open up. also considered acetylene torch tip cleaners but i think they might be a fraction too big, and might not be able to cut into.
 
if the design proves viable, hopefully i could fine tune print settings for more predictable hole success.

*Mar from CircularKnitic suggested using solenoid to operate the needle movement
**due to the limited travel distance, i think some sort of lever with a bearing will be needed
**will need to transfer the lever's circular motion into linear

*ordered some nickel powder. readings say edison batteries had nickel flakes layered in the cells.
*perhaps could define p4clear possibly as low as 1/2 of -p4rampH? maybe -1/3*p4rampH ?
*going to print new cages double the height.
**this would reduce needle travel and shrink mountain
*might look over the ultra smart charger firmware
*Applied to show CircularKnitic at MakerFaireTulsa https://tulsa.makerfaire.com/
**would be nice to tweak some things if its not too difficult
***if it it maxes over 2V lower the mAh's
***disregard internal resistance errors
***does a weird thing where it wants to discharge some before it charges


need to read more about typical charge scenario

also, found this nifty website to compare text http://text-compare.com/ , i think theres a bug in the cage scad file

*discharge data was poor
*documented sock sized circular knitic build
**voltage reached minimum after 15 seconds
**[[User:Dorkmo/Builds/CircularKnitic-Sock]]
**durring charging the part of the wires coming out of the cages were gassing the electrolyte.
***cages were not charging


it seems that the nickle wires coming out of the cages were alone acting as the electrodes. The resting voltage was around 1.2V which is in the range of what would be expected. i lowered the electrolyte level below the wires and it changed the charge behavior. voltage would max over 2V quickly. In the config I lowered the max charge mA to 1. used the NiCd trick to start charging. I expect the voltage will plateau quickly. will be interested to see if internal resistance changes. will let charge for a day.

*Circular knitic build and design changes


*hooked up test battery to the ultrasmartcharger.com

**had minimal success, wouldnt recognize as a battery
**it would see it when in battery recovery mode
**but would immediately errorr bc max voltage of 2V around 2.04V
*found the custom [http://www.ultrasmartcharger.com/phpBB3/viewtopic.php?f=3&t=68 configuration utility] on their website
**tried to tweak max voltage but even the custom max is 2V
**after a few tests tried lowering the charge currernt to very low
***set to 10
*tricked the charger by tapping a AA NiCd battery on the leads before the charge
**not sure if this actually made a difference but it seemed to help
**running firmware 0.524
*charging continued without error led flashing


after a few hours i pulled the SD card to check the data. the data seems to show that the cell was increasing its voltage. and was indicating it had reached about 25mAh. i assume that is calculated and not truly measured like voltage. in the next couple days i plan to run a full charge, discharge, charge, discharge, charge analysis. i think that will give a true capacity rating.
*started a BOM scad file to auto generate bolt size/length/count output
**formatting is not very user friendly but nice to have calculated output


here are the data for the fist charge attempt [https://docs.google.com/spreadsheets/d/1M6tXRpsHZgIKi1d6b9bUxMs2JmeDEeli_B36ayJOHfY/edit?usp=sharing google doc]
