"Demodulator"

When looking for alternate ideas to transmit data off the G1 other then the serial connection (which would require Linux kernel modification on the Android platform, but we're saving that for another time), the idea came to do it "old school".

So my electronically gifted little brother came up with this design:


We output plain pregenerated analog audio signals describing bits with the same modulation as the serial line to an amplifier and a micro controller which in turn converts them to the digital serial stream.

P.S. First test was done using the Christian Bale Terminator 4 outbreak remix ... looks like swearing would look like a string of p, @ and P characters :P
