    hi all
    i run my car mp3 via 300watts power inverter. i hook it up and it run like a day then it won't boot pc up anymore. if i use ac line at home outlet, it boot up fine. as soon as i connect the ac outlet of the power inverter into the pc it just power up and that is it. no video, nothing show up. cpu fan not even spin. I think my power inverter is not produce a good sinewave or so. what do you think ? and what power inverter you would suggest me to get instead STARTPOWER that i bought from COSTCO.

    I am building a sproggy mk2.5 DC-DC power supply. I am using this supply because it seems to be better to utilize the dc voltage that is already there in the car then to go from DC to AC then back to DC. There are plenty of places to pick up a DC-DC power supply or you can get some plans for one @ www.sproggy.com. Hope this helps a little.

        A guy I know has a company and all he does is print up boards.. I got the pcb layout off of sproggy's page and all this guy has to do is run the board off that. My dad was thinking of having a few of them printed up to see if others out there were interested in buying them. The only problem is I dont know how much and when they would be ready. I can get that info if you want. As for the LM2587 I got mine from national as a free sample. The coils I have not got yet because coilcraft knows whats up with the whole free sample thing and if you try to order them they say "we will not supply parts to make an MP3 player"... However you can buy them... I am trying to find parts comparable to those to buy..
