Copper Plating
unfy:
3.3v and 5v power supplies at decent amperage can be had fairly cheaply ($5-$15). It's something I'll be keeping in mind when upping bullet counts if I feel there's a power limitation.
As seen in the previous pictures, there's crud on the 'staples' that make the contact to the lead. Not entirely sure what's going on there or how to clean them easily. While they're sturdy enough, they aint super duper strong.
Also a fun note, the plastic fork/knife/whatever handles I was using ... don't like acetone :).
Still need to come up with a bullet prep "solution" (whether if it's physical or 'pickling'). I'll start pondering ways of safely working with acids that's as idiot proof as I can come up with.
Haven't really come up with a decision for attaching copper plates to wiring yet (that would make connect & disconnect easy for disassembly & cleaning). Decently sized copper clips seems like the easiest solution, but those usually aint cheap.
Something using copper washers, a bolt, and wing nuts might be easy, I dunno. Even soldering some copper washers to regular clips might work out. I'll look through the plumbing section of hardware stores for inspiration (lots of weirdly shaped copper pieces around there). If I trusted it, simply running a copper wire down the side of the pvc and let the copper donor plate "push" against it might even be good enough... but that seems to leave things to chance.
If i do something where it's:
__ <- copper plate bent to apply pressure against side wall

I... dunno. Maybe. I'll have to look at stuff and fiddle.
I'm basically wanting to be able tear down and reconstruct the plating stuff easily. Take it apart and throw it in a big bin, and reassemble it easily. It's a desired goal for the project (means that it's easy to work with and not fickle... and can be stored easily).
Continuing to cut some sections of pvc pipe each night. It's annoying to do without a band saw heh.... so... spreading it out while pondering.

Found the answer to my dumb question - disregard this post.

So, walk into Menards today for a Valentines Day gift to myself (see my forum post signatures).... expecting to spend $40 and get out of there.
$125 later.... RAWR.
Ended up picking up a couple tools, so it's not that bad. Still frustrating.
Another 5 foot section of 3" pvc pipe. 10 foot is a good bit cheaper-per-foot, but kinda a pain in the ass for me to deal with.
3.5" hole saw and associated arbor. A drill bit for metal just to make sure I don't mess up bits I already have. Some wire crimper things for terminal lugs (i typically deal with electronics, not electrical).
2' x 2' x 1/2" (??) piece of plywood to make thing to hold cells in place.
Some 1x4's to frame it in, including some 1x2's to help frame... although thinking about it now, this might not be the correct framing solution for limited tools I have. We'll see.
Some more 1x4's for what I think be used to hold the metal stuffs for clothespins. Not going to go with a "lowering" mechanism just yet.
Six 2-foot pieces of 3/8's inch rebarb... just in case i decide to go that route for the clothespins.
Six 4 foot pieces of galvanized fence straps. About 1/4" by 1/2" by 4 feet. Basically used for terminating chainlink fence I think ? Was cheaper than the metal materials in the welding area. Anyhoo, cut into three of them in half (~2 feet each), these will be the power bus bars for the copper plates. The other 3 cut in half is also an option for the clothespins (instead of rebar).
For s&g, also picked up a 6 terminal (12 stud) terminal block, some C crimp on wire terminals. Dunno if the terminal block will serve an actual purpose.
Also some O ring crimp on wire terminals for use with the copper plate crimp things connection to power bus bar.
Lastly grabbed a few 4 packs of some regular stainless/aluminum clamps ($1.70 for 4 ?). Given their shape and size, and that they have a nut/bolt wire attachment ... they actually might do nicely. Kinda weird, but given their clampping mouths, I think it'll work.
Looking at copper stuff in plumbing - it's all copper plated which is useless for donor plate hook up (it'd just strip the plating off if submerged). There were some copper washers in the nuts/bolts area, but none were fender washer style so ultimately useless. There was some copper stuff in the electrical area, but it was over priced.
edit:
Tonight i'll start penciling in everything in the wood to see how it looks. Am hopeful!

I hear that construction sites are a good place to get copper, as well as AC units.

Do you actually find time to hold down a full time job :laugh:
