Progress is slow, mainly because I'm freaked to the max on making a mistake somewhere that will cost me $200-300 later, every calculation, CAD file is checked repeatedly, I know nearly every measurement off the top of my head, in case EMP bombs my house, fragging my PC
Anyway, I've been tinkering with ideas for a while now after seeing Jakes solderless urethane packs, and I've really wanted to make some now that I have A123 cells all over the place. I finally came up with something that should work!
The idea is a pair of 10mm thick UHMW plates that hold the cells in place, inside those plates are 3mm thick copper buzz bars (Would easily take 2000amps...) These bars are spaced 1mm from the cells themselves, in each buzz bar there are two holes, where a brass/copper set screw is firmly tensioned against the cell wall (very carefully, otherwise dinted cells and bust stuff). I'll be interested in building and testing a few of them now. I've also worked out a way to make them modular in single cell form, although it will take up a little more room then I would generally approve, but might be useful where you need to quickly add another cell to a pack or remove one if damaged.
Influenza will use two of these 300gram units in it (I went two 3 cell packs because I need to space the weight evenly across the chassis), for a nice 19.8v @ 600grams of expended weight.
My supercharger and laptop have been paid for now, so I'll be able to purchase the brushless gear for the weapon after the next pay cheque (Rego takes that fortnight's savings ) So I'll hopefully have something to say about that stuff to in relation to the weapon _________________ https://www.halfdonethings.com/
