    Not quite true

    I use CrystalCPUID to underclock and undervolt my AMD Sempron 3000+ (Palermo core) to 800 MHz @ 1.2v when it is idling. Power consumption of the CPU goes down to about 21W in this case. When CPU...

    I think your idea is to switch between the 2 ATX PSUs (Opus or Morex). You could make one using either (1) relays or (2) power MOSFETs. Option 1 is easier - just get the right number of relays (one...

    It could be lots of reasons, eg mechanical/heat problem. Check that the CPU HSF hasn't come off. You could also try the "shake test" - while the car is stationary, grab and shake the car PC to see...

    I'd agree with that. That loop around the variable cap is definitely part of the tuned circuit.

    Hmm, unless my memory fails me, the 5V section of the Sproggy uses the MAX787. The +12V and -12V section is the one that uses the NS part (LM2587).

    Sorry, 1N5821 as in the circuit although 1N5819 will also work if you keep the current below 1A.

    You can calculate the current drawn by the load using Ohms law. Since the voltage is 7V (on load), the current is 7/12.7 = 0.55 A.
