*ordered some nickel powder. readings say edison batteries had nickel flakes layered in the cells.
*going to print new cages double the height.
*might look over the ultra smart charger firmware
**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
 
=march 8, 2015=
 
*discharge data was poor
**voltage reached minimum after 15 seconds
**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.
 
=march 5, 2015=
 
*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.
 
here are the data for the fist charge attempt [https://docs.google.com/spreadsheets/d/1M6tXRpsHZgIKi1d6b9bUxMs2JmeDEeli_B36ayJOHfY/edit?usp=sharing google doc]

*cage floats in water, need to constrain

1st attempt
*iron powder held in cage
*nickle powder seeped out lower half of cage mesh
**may need steeper and/or thicker mesh wall
*small cracks in tub began to leak
**need to finish optimizing SCAD
*nickel wire held by cage lid well
*used 1.5V
**not sure if charging
**charge analyzer would help much
 
 
=dec 7 2014=
 
printed tub with grooves, did a decent job of preventing layer splitting. seemed to do best when the grooves on one face staggered with grooves on the joining face.
 
spent some time shifting existing grooves up and down but finally realized need a different strategy
 
redoing some of the SCAD groove module to allow for more tweaking so the staggering can be ensured. plan: will tweak groove width one side and set it for the rest from that one. then tweak angle on adjoining side and copy angle to side opposite it.
 
*no word back from battery charger dude. might not work out.
**ordered a 1.5v voltage regulator from digikey to do a dumb charge

*added grooves
*added eyelets
**need to finish the other two sides
**not sure what to put through the hole.
 
=dec 4 2014=
 
*might put slanted grooves on the outer wall to try to cut down on printed layers coming apart.
*guna do a larger lid to cover multi cells and have 2 pole mounts
**will have donut mounts on sides that align with mounts on outer walls
 
 
=dec 3 2014=
 
Ordered a battery analyzer/charger. Should be able to test a single 1.2v cell up to 20Ah.
 
Probably will only use for design/testing. Would need something else for regular use at 12v.

need to build in some adjustable leeway to accommodate imperfect slicing and printing
*tweaks for lid
**going to reduce total length and width of the bottom part of the cage lid by 0.2mm
**need to print without a skirt (oops)
**might chamfer the bottom 0.5mm

*tried to optimize size a little. attempting to get a 12v 10 cell within 200mm max dimension to fit 3d printer.

**not really sure how to calc density of powders, so it may be way off. gives an absolute max though.
