    Biofeedback

    I am interested in neurofeedback and biofeedback techniques such as galvanic skin response and the like. Commercial units are extremely expensive but in principle such items are simple to construct and reasonably cheap in terms of components.
    My problem is this:
    I can output a changing resistance or voltage but can anyone point me in the direction of interfacing this with a computer port so as to produce a changing tone or line graph.
    I hope all this makes sense.

    Your best bet would be to use a DAC (Data Acquisition Card) such as available from Amplicon, although there will be plenty of other sources within the UK.
    This I believe would be your cheapest option, or do you need something stand-alone to plug into a port of any computer?

    Thanks for the response. I will explore Amplicon and the like but the standalone option would be ideal. Any suggestions?

    Try Pico Technology - they have a small unit that plugs into the parallel port and seems quite reasonably priced.

    Otherwise, I'd need an idea of:
    Number of channels
    Resolution
    Budget
