Android Bluetooth Oscilloscope

ProjectProto's oscilloscope. Great project! Schematic, Project source codes for Android and dsPIC available on their website. I'd love to build one for myself :) Many features could be added to make a real oscilloscope from this (triggerring, data storage, etc) Of course, bandwidth will be limited to 1MHz, but this is enough for audio signals... Or build Android-based multimeter.
