looks great...did you build the "circuit" yourself? I have been wanting to make one for a while, and have seen alot of "plans' and such on internet, but I don't read schematics and not exactly sure how. Still looking for some real good instruction that details the little steps. I can solder ok, just need a step by step. Please post if you have a good tutorial on soldering up the circuit/board. thanks... Again, looks great.
