Wire Gauge and DC-DC Converters

Lycurgus...thanks a bunch dude. Now i can actually start this thing because i know where all the wires go

Errr.. your missing one thing. You need the negative input to go into the ground too!

Ok, so here's an update...

I finished the soldering after your comment spike, but i think i got everything correct (do you mean that the negative input is also attached the ground prong of the converter?). I supplied a picture of it below so you could evaluate it for yourself. I basically used a radioshack PCB board, a 100uf capacitor, and 22 gauge wire. It might be hard to see what i did in the picture so i'll describe it here:

I soldered the chip to the board; making three seperate lines for the current to go through (thats how the board is set up). Each converter prong has its own line. I then soldered the positive end of the capacitor to the output prong of the converter, and then soldered the negative (or ground) end of the capacitor to the ground prong of the converter. The red wires you see are soldered to the joints directly in front of each seperate line (one for the output/positive cap line, one for the ground/negative cap line, and one for the positive input).


Here's the job i did:

If you b1tch about my soldering job, i'll understand; i know how badly it sucks If i did anything wrong, please let me know, it'd be much appreciated.

Do i attach the negative battery input to the ground prong of the converter? thanks.

"negative battery input"... you mean just the negative terminal of the battery? (if anything, thats an output).
if so, yes. in general, all your negatives (grounds, whatever) on everything go together.
