    Schematics Variable current 12v 60A to 0A

    Dazza, Lets try to build one module at a time and interface them together along the way one by one. Then we take care of the different issues as they intervene. What do you think? ;D

    over unity is here

    Well this is the way it is: For every transformation of energy there are losses. Even a piece of copper wire has its resistance and there are not much you can do about that. If putting together things like motors, capacitors, inverters, alternators, and generators they all add to the losses.

    Schematics Variable current 12v 60A to 0A

    Ok, where do I start? Well I think R1 is not supposed to be paralleled with the wire that comes from Q2: s collector!? The inverting input of U3 (pin2) will not have any reference besides the voltage from R1 (floating?) and U3 will die from a voltage this much higher than its supply I guess. Q5...

    FireFly, If you have the datasheet for the cap often there is a layout that can be used for drilling the pcb.

    MP, I agree 100%! Kumar, If an SMPS would have all these drawbacks and problems you can ask yourself: Why do we have harddrives, CD Roms, DVDs and half a dozen fans in the computer when the SMPS just don

    PhuocTran, Does your soundcard have a line-in connection? You will need some kind of attenuator to reduce the input signal and to protect the soundcard.
