I'm at a standstill trying to figure this out. Do Chris Crawfords diagram apply in this situation since my transformer is only 12 volts? Any help with the wiring would be much appreciated. I have no idea what I'm doing. :confused:

I'm not sure what you're trying to do but i may be able to help. What voltage do you need to run your device?
 
Thanks guys. I figured it out after studying an online schematic (not Chris Crawfords). I need to make a pad, but got a decent etch with a q-tip.

If you want a good etch pad for not a lot of money, get yourself an appropriately sized carbon motor brush, as in a large DC motor. They'll already have a lead to solder a plug to, and you can shape them down as you see fit.
 
Hmmm, the winch on my 4-wheeler is broke. Do you think it would have a brush in it that would work?
 
I'm thinking of more like an industrial sized DC motor; the kind of motor that weighs several hundred lbs.

The winch motor's brushes will be a little too small, IMO. Granted, I suppose they're a little larger than a q-tip.

If you know any electricians in an industrial setting, they can likely find you some used brushes. A motor repair shop will likely have loads of them too.
 
Oh, and stay away from the "copper" or otherwise "alloyed" brushes. They start oxidizing.
 
Go on amazon and search motor brush you can pick up a three pack large enough for etching for something like $7. They work really well with felt and a proper electrolyte.
