Strap me down. This schematic for a digital theremin device gets me so hot. I want to play with my NAND gate until my VCO oscillates uncontrollably. I want to overload my quad operational amplifiers until they distort from being way too over driven (some geek will then point out that there are no quad op-amps in this schematic--douche bags). I want to tweak the pitch until it squeals in ecstasy, whooooooo-wheeeeeeee-whooooooo!
What gets you all techno TIGF hot?
