Ubnox-o-Phone: Gah

Sam Holmes built this odd amplifier/synthesiser just to piss people off. It uses the Weird Sound Generator and the Ruby Guitar Amp to create crazy sounding noises that will definitely anger anyone within earshot. He even added a key to turn the thing off and he films himself in the woods, on a trampoline, and near his mailbox, three settings which are absolutely essential to all DIY device videos.
