I've noticed a lot of free software for analyzing seismic signals. So I thought that I'd make 8 geophones out of speakers(coil and magnet), hit a metal plate on the ground with a sledgehammer thereby triggering an interrupt, and record the reflected seismic waves as detected by the geophones as a voltage change.
I'm new to microcontrollers. I've been messing around with VMLab, programming for various ATMEL chips, but the ATSK600 is too pricey for me right now. And all I need is:

battery powered to operate in the field.
read 8 channels, each about 20 times/second, preserving the timing from the interrupt.
save the data, maybe on a flash drive attached to a USB port.
and all for less than five bucks!read 8 channels, each about 20 times/second, preserving the timing from the interrupt.
