    now looking for a small but robust dcdc psu. I know the DCD-USB-200 is the on to go for but if you know of any smaller devices let me know. I have had the m2-ATX for five years without issues. I even thought of using it fot the NUC since the NUC accepts power from 12 to 19V.

    apparently the NUC is fine for 12v input.

    You will need a way to know when the car is shut off so you can automatically shut down.

    Read that thread carefully. Yes the NUC will work on regulated 12V (like what you would get from your DC-DC device), but it will work harder. More heat. Pumping the volts up to 19 will allow the NUC to operate more efficiently. The best setup would be for you to take the DC-DC regulated PSU, set it for 19V and run the trigger circuit from the DC-DC to the NUC. By the way, the header pins on the NUC are no different than any motherboard. Those two soft power pins are present on all of them.

    I'm getting ready to do a project very similar to this, so I'll be watching your progress. Good luck!

    Nuc power brick says : 19v 65watt max and 3.4 amps.
    Running the nuc at 12v means you will be drawing 5.4 amps to get the 65watt.
    The dcdc-usb can handle 10 amps and the dcdc-usb200 15 amps.
    Will this generate more heat i don't really know.
    Now according to this test http://www.legitreviews.com/intel-nu...power_124251/7 the nuc running at next to full load does not go above 30watt !!! This means a current draw of 2.5 amps with a 12v power source vs 1.5 amps with a 19v power source. Figures are small but I still don't know if running the nuc from a 12v source will shorten its life or generate more hear.

    About to order a temporary screen so I can install mine. It is all running and functional on my desk.

    I know in PM you said the P1900 was too big, but I think it is a better solution and see it is small enough to hide somewhere in the dash. Really easy to extend wires and hide it somewhere. For reference:

    Carnetix P1900 is 4.6"x3.25"x1.75" Has 19v and 5v to power accessories so you don't need a second power supply

    DCDC USB200 is 6"x 2.2" x1.1" (metal enclosure specs, not the board - bare board is smaller obviously)

    You can also use the p1900 to provide 12v regulated to your screen as well. Just get the 5v addon then it can output 3 different voltages. Very good unit SNO
