    An epia Altenrative, if you have a VGA screen.

    Been thinking. Most people have targetted Epias, but then unless they build a sproggy, or buy an Opus, have struggled to find a regulated PSU that gives 5A12V, and can cope with under/over voltages.

    What I'm suggesting would still need a tank circuit for when cranking, and would need a VGA screen (what we are all working towards anyway), but would seem to be ideal, if you could get your mind off Epias.

    Think about using an iWill ZPC

    with a

    With a Targus 120w laptop car cord


    Details are on page 8 of This PDF .

    between those two, the cost should be under $400USD for the barebones and the PSU, plus your choice of Laptop HDD/DVD/CPU and DDR ram. And I reckon it could look quite sweet as part of an Amp rack build.

    Just had a look at the Targus UK site, and they don't even list the bloody 120watt adaptor.

    typical.

    well I'm using an EPIA with the dcdc Morex power supply (both available from www.mini-itx.com and a targus adaptor PA350

    It comes to $600 Aus for the lot.

    Had a look. MK3 is excellent. Sort of thing I'm planning, if I can pursuade the Ebay seller to send the screen COD like they offered in their auction description (just bought a 12" black TFT monitor).

    Found a UK supplier for the 350 :-

    Would something like this be feasible?

    It only outputs 16 or 19 volts, but you could use a potential divider very easily to give the 12v the Morex etc would require.

    You ever bought from Watford Electronics before?

    Once a year, they have (or used to have) an end of line clearance open day.

    Most of the time, it is returned and reject stock that is sold again at a discount.

    I bought a budget video card from the last one I went to (about 6 years ago).
    First card had no drivers, and no address to download them.
    Second car had a sticker on the bag, "Your damaged card has been repaired".
    3rd one worked OK

    Loads of people that day where back there exchanging faulty goods.

    I suspect that in order to use low value enough resistors in your potential divider to provide a stiff enough voltage source for the Morex, you will end up dissipating far too much heat in your potential divider resistors.

    A little better to use a regulator.

    BTW, Maplin have something similar on special ATM 19.99.

    Used to be on their website, but can't find it now (not the Juice supply, cheapy branded one, same as the Ebay ones). something like 3.5A 15v+ max at 70watts max.


    This one is actually the same one as I saw in local Maplin store as "New product" 19.99 introduction price.

    Actually now you mention it, I do remember seeing that in Maplins the other day, but discounted it because of the voltage. Here it is, with some other potentially suitable Maplin offerings: -

    http://www.maplin.co.uk/Products/Mod...moduleno=36453
    http://www.maplin.co.uk/Products/Mod...moduleno=36455

    Assuming all these are switched-mode, it must surely be possible to open then and tweak (with the correct knowledge) the resistors at source to get 12v?
