    Hi,

    I'm planing a Velleman wiper motor sim and build a Velleman K8055 test board. I've searched around the forums and found that:

    First: Pretty good idea to solder the pots directly to the IC. But wich pots should I use to get the best result? 1K, 5K, 50K or higher?

    And second: My idea is to grab a 19 rack case and put a micro ATX mainboard with onboard CPU and all that other controlling stuff like the Velleman and the H-Bridge into it. Can I serve power to all these goodies by one single (but powerful) computer power supply?

    700W 12V computer power supply for:
    1. The micro ATX control PC
    2. Velleman board + some relais
    3. H-Bridge + wiper motors

    The micro ATX shouldn't need more than 150W, the Velleman just a fist full watts, but I dont know how much power is needed to fire up both wiper motors.

    Respectfully,
    Jakob

    I have another short question: Is it possible to drive a 5V motor or servo (for a tacho/gauge) directly with the analog output of the Velleman board?
