Scott has been doing experiments with reading biomedical signals like electrocardiograph. He relised that he needs a simple multichannel module that would read sensor data and send it to PC. So he came out with multichannel device based on Atmega48 microcontroller which interfaces to PC using USB.

This is really simple solution that consists of AVR microcontroller, FTDI USB interface chip and low noise micro-voltage amplifier. PC code that captures data from USB port is written using Python so there is no problem to run it on any machine that can run python. Device is great for any experiments that require multichannel analog data logging.
