    DIY DC power supply???

    So I was surfing around trying to find the pinouts on itx power supplies so I could use one of my spare dc power supplies for external devices... and I found this...

    http://home.concepts-ict.nl/~cybersake/carmp3/

    Complete plans to build your own DC power supply, don't know anything about electronics (well at least not putting together a power supply). But I thought someone here might find it useful.

    I did a search on the website here and didn't come up with anything, but if this has been discussed before, sorry...

    Yeah... seen it... no thanks, no DIY crap here... I have neither the time or patience for it, that and everytime I get a hold of a soldering iron I end up with 3rd degree burns , just hadn't seen it, and seemed like a decent design. Good for people to have options ya know?

    Yup

    Good find, thanks for the link. I wonder if it can survive the crank.

    The spec's of the supply are:
    Input voltage: 7.5...19V
    Transient protection by a 20V transient suppressor diode
    Output voltages:
    +5V / 5A -5V/0.2A (Step-down)
    +12V / 2A -12V 0.2A (Step-up and Step-down)

    This is only an AT type PSU, most modern motherboards require an ATX compliant supply. But it looks good for what it does.

    No worries none...that can always be converted as an ATX PSU

    Just rip out the ATX function of a sproggy or something, mod here and there and you are done, not the end of the world

    The only difference between AT and ATX power supplies are the connectors on the motherboard. So, just use ATX connectors instead of AT.
