[[Dorkmo To Do List]]

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.

*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
**going to put a cone shape hole at the bottom of the wire holes to keep from closing up
 
 
=nov 22, 2014=
 
*tried to optimize size a little. attempting to get a 12v 10 cell within 200mm max dimension to fit 3d printer.
*changed the cage lid so it can be skinnier.
*added some calculations to attempt to predict how much chemical will be needed for the entire battery
**not really sure how to calc density of powders, so it may be way off. gives an absolute max though.

*printed two cages. look pretty good. better than i expected.
**might slim it down so it holds less powder.
 
*ordered chemicals. might be a few weeks.

made some stl's. guna try to slice.

mostly finished with the scad work. could clean it up a little but its working. getting printer back in shape, maybe next week.
 
=nov 14, 2014=
 
*reworked the scad for the mesh module, i like i better.
**draws a big matrix of cubes, then rotates it, then gets the intersection() with a cube the size of the wall
*guna do a simple lid next thatll silicone onto the top of it
**might use a small 'rope cleat' to tie off wire going into cage

"Object isn't a valid 2-manifold! Modify your design. See http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/STL_Import_and_Export"
 
i tried using the mirror() function to make a mirror image of the mesh. apparently that was a bad idea.
 
=nov 9, 2014=
*mirrored sides
*need to add divots for clip in
*need to figure out problem with angles above 45
*need to determine cage height from tub height
 
=nov 6, 2014=
fixed a bug and centered holes
 
=nov 3, 2014=
 
been slowly working on an [[OpenSCAD]] file for the battery idea. got the holes aligned and angled how i imagined them. im a bit of a noob so i probably did the code in the most difficult way imaginable. [[User:Dorkmo/Ideas/Battery/SCAD]]
 
[[Image:Image20141103-batteryprogress.jpg|400px]]
 
*need to tweak the height and width of the mesh compared to the wall itself.
*also need to make some divots near the base for it to snap into the base of the tub.
*also a lid.
 
=oct 12, 2014=
 
revisited battery. sketched a single cell idea. would hold the ni and fe powders on either side of a printed grid membrane. not much surface area optimization. would like to test something simple and then go from there. need to check on how much electrolyte needs to be around.

*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
