    looks like youd need a microcontroller, its kinda setup like a matrix.
    apply a voltage to brown, then read blue yellow and green. compare it to the last color you had and you now have rotation...

    ahh, i see. well that looks like a nice changer, the jvc ch-x1100rf, not just the jvc ch-x1100. the other ones manual showed it connecting to a jvc head-unit. well that one looks fantastic. should be...

    the factory radio is a pain in the *** to interface with. it uses fords proprietary acp protocol. you can buy an expensive PIE adapter that mimics a cd changer and lets you use an aux in, or you can...

    just curious. are you installing this with an aftermarket jvc head-unit?

    you could take out the spare tire and put it under there, other than that there's not much room, only free spaces are the back left by the radio tuner underneath the carpet or under the back right...

    i would check for any bad capacitors (i.e. bulging heads, discoloration, or they just get really hot). barring that, you may add more capacitors on the output line to try and get rid of any voltage...

    they do, they are called amp-hour meters and are typically expensive. they use them alot in renewable energy applications for measuring the energy left in a battery bank.
  9. and now for some numbers! so i hooked up the...

    and now for some numbers!

    so i hooked up the ammeter, and this is what i got. 8 amps during startup, settles down to 6 amps during bios, and once windows has booted and its idling, between 4.9 and...

    tried 2 schmitt triggered not gates in series, that didnt really work out so well. i think i destroyed that chip anyway......... which is why i bought 3! i think i need to clean up my circuit layout...

    the 34063 was not outputting a proper waveform. the ideal fet gate drive is a square wave wheras this was a triangle. triangle waves keep the fet in linear mode for far too long causing extreme...

    30 amps units, running them in linear mode. the output waveform was pretty much a triangle with a peak of 2 volts (shivers)

    well, the mc24063 thing has been interesting. their output waveform sucks and my fets dont like it, but they seem to work for a while, going to experiment more with that. boost converters are hard to...

    well, some progress. found that those cheapo walmart phone chargers make an excellent 5v standby power source, got rid of the lm7805 (pretty warm). i took a look at the switching circuit inside, its...

    well, i just destroyed two motherboards today. my GF hit the power cable and the mobo didnt like it :/.... shortly after replacing it my hand hit the pci riser and it knocked it out, shorting some...
  17. quick tip. if you use this converter, don't touch...

    quick tip. if you use this converter, don't touch the little thin wire connector. i tried to power a small (1 watt) amp from this. apparently it has a connection that connect to the feedback of the...

    alright, so heres a few things i've learned so far. on the dc/dc converter, all you need to do is splice your 12 volt wires into the 2 16 volt capacitors on the board closest to the slot connectors....

    well, im pretty sure im going to spend 5 times the money and get 1/3 the performance. but i have like 30 sticks of ram several motherboards and a pile of power supplies lying around. Worst case i...
