If you do, hook up a switch, and see if features work. Basically mock it up outside your chassis.

    Then hook all your other stuff up. Try to shorten the amount you strip from your wires, you are stripping too much insulation off the wires, and that is a recipe for shorts. You need less than 1/4" to cover the pad, don't strip that much, particularly if your jacket melts back, which it looks like it did. Use flux, pretin the wire, and bloop it quickly. Looks like you're trying through-hole soldering, but if you watch madcow's videos, he goes on the pads, not through them.

    Thanks for the advice! I've desoldered everything from the board so far and am going to do what you suggest and see if that works out. I'm also working on shortening the wires on everything so there's less area to cause a short. The only in-hole connections made were merely to test if everything would work (no soldering just contact with the pad). The battery is soldered onto the pads but I just placed the other wires into holes so that I could test if other connections work. I'm also going to re-wire the switch so there's not that ugly melted mess.

    That would be very much appreciated! I bridged the L1 and Neg. pads accidentally but I removed it before I took any pictures. I don't believe any other pads were bridged but there's a chance that they were. This is also my first time soldering a board so it's not as neat as I hoped it would be.

    You can email him at and work it out from there. Tell him FJK sent you.

    "Yeah, yeah, I've heard it all before... you want blindingly bright, super loud, running 1138 blinkies off of the cheapest sound card you can find AND you want all of it to run on a battery the size of a dime, and run for a very, VERY long time. That one cracks me up every time..."
