not sure if mentioned yet, but the answer is ne me quitte pas by jacques brel

ah yea, the input impedence (among lots of other things concern me). just for completeness of this thread, the voltage offset is completely tuneable.     much less likely to give it a go now, but if i ever play around with it ill definitely use something cheap :)

I'm guessing I'd have to code up something to send the digital output from the mp3 to the serial port (not a problem), since that is how the setup is connected to the computer...

so it's got both DAC and ADC   I can't seem to get the sampling rate for the DAC, but I see that it is 200kHz for the ADC (not sure if that means its the same for DAC). These are the specs specifically for the DAC:     Analog Output: Number of channels 4, pseudo-differential    ...

So I have access to loads of amps/DACs made specifically for single cell electrophysiology. They look something like this: http://www.moleculardevices.com/Products/Instruments/Conventional-Patch-Clamp/Axon-Axoclamp.html   Does anyone know if it is possible to use these as an amp for...
