    Hmm.

    Correct me if I'm wrong, but doesn't the Cubid case already have a DC-DC converter? So this plug is really just an extension cord, right? It basically won't work for anyone unless they have a Cubid case [http://www.koolnquiet.co.uk/index.ph...=104&cat_id=32].

    However, considering that the cases come with stuff... are they usable as a carputer? The AC-DC conversion (AFAIK) is done outside the case using the included PSU.

    [edit]
    Which of course has been discussed before (but not limited to):
    A 12v dc-dc 12v power supply
    No Carputer YET.
    A car I'm designing...

    Heh, yeah, theres been a lot of discussion about the cubid motherboard as you've discovered. And it sounds like its just a cigarette plug with a properly sized barrel adapter (power cord), something you could make with parts from ratshack or any electronics store.

    Am I being dim here? Lighter socket to cubid power supply (No brick needed) and car computer is powered. Full on DC-DC power for 40 notes?

    For 4 dollars, it just looks to be plugs, and no regulation, so itd pass the ~14.5vdc from your cars alternator dirrectly to the cubid psu, which doesnt have a 12vdc rail, and simply uses the input, so instead of 12vdc, everything that uses 12vdc would get ~14.5vdc.

    Hmmm...that thought occurred to me too. My point though is, why would they sell a product that could potentially destroy your system? I'm going to email them and find out more I think. WIll get back with results...

    OKay - been searching round some more and turned this 12v regulator for cars from Maplins. My electronics is frankly awful - could it handle a Cubid or Morex power supply?

    I know that people have found some 12v 5a linear regulators out there, and I know they've been mentioned on this board too. The only problem with a simple linear regulator is that theres a voltage drop across it, so the car would probably need to be running (14vdc input). I think there have also been other circuts discussed on the board.
