Where did you get the little metal bits inside the shrink tubing? That'd be a nifty thing to have! Also, when you refuel your blow torch, hold it upside down so the can is straight above it and you'll get more fuel in to it that way. With my gas soldering iron it lasts about twice as long if I fuel it that way.

It frustrates me that the arduino's have those little holes to poke stuff in to, but none of my wires are wide enough. I wish they could get some breadboard type stuff that can take any gauge of wire so we could just tin the ends and still have a good connection. That's the main reason the Arduino Nano looks funky to me, just that I get to use a breadboard on it. :)
