I have a bunch of photodiodes and I want to interface to these to a computer using my sound card. I have 12 sensors and stereo input samples at around 96000hz. My idea is to connect 12 sensors to each line and have them turn on or off at a specified offset so that the total output signal would...

Thanks for the detailed response. I'm wondering if photodiodes will have the sensitivity necessary -- generally avalanche photodiodes or photo multiplier tubes are used although I've heard diodes have worked too. If I use a diode which would be best in terms of sensitivity to small amounts of...

Hi, I'm a computer scientist w/ very little hardware experience. I've been playing with the idea of using NIRS for a brain computer interface. The basic principle is pretty simple: You have a laser diode and a detector that is 2-3 cm away from the diode. Unfortunately I have almost no...
