    Hi,
    thanks for the info. I bought almost all of the necessary parts. I will go by the digital pot way.

    Edited:
    ok i have it clear now why the step up converter. To provide +- and ground to the opamp. Just figured that if using PC ATX power supply to power everything it has +-12V so the step up converter is not needed.
    I think of powering the diode and the DAC from the same ATX PSU. Will see how it works. Will use Lasorb of course.
