    For 18$ inc delivery I can supply some of the parts to the mk2.5 psu on my site
    http://sproggy.mp3car.com

    Parts included:
    1 etched fibreglass, tinned and drilled PCB
    2 MBR745 diodes
    1 MBR340 diode
    1 MUR120 diode
    1 SA28A diode
    1 1n5819 diode
    2 1n4002 diodes

    This leaves you get the free sample parts and the other remaining parts which should be available from any good electronic supplier

    I have designed and built an ATX DC-DC PSU that is fully ATX 2.0 compliant, including auto-shutdown (no serial port needed!). It features an integrated microcontroller for "brains". It draws around 2.6A from the car while powering a Celeron 400 and hard disk running Win98.

    I have successfully built 2 prototypes based on my new design, and I just shipped a prototype to a customer yesterday for use in a marine application using GPS and DVD video on boats.

    The cost will be around $100 for ATX, $75 for AT and I should be able to take orders in a couple of weeks once the etched boards come back from the PCB fab company.

    Check my website in a few days for more information.

    Question

    pardon my ignorance. i am interested in using the astec laptop power supply for my (yet unbuilt) car pc which will be using a p-120mhz,
    AT motherboard,
    lcd with isa controller,
    2.1gb hd,
    soundblaster compatible pci sound card

    will the astec laptop power supply support my setup? has anyone tried a similar or more powerful setup?

    one more very simple question, where can i find the cigerette lighter plug which will be connected to the power supply?

    thanks, for any info!!
