A DVD player will be really easy as you can use one from a pc, while the playstation would need the use of a good graphics card to accept external input device.
I have a dvd player and a ps2 in the car. Can I get a laptop or a pc screen to power up in the car, and accept a signal from either of those. Ie can it be coverted over.
You can get a computer screen to work with a PS2 etc etc.
You just need a lil box! :-]
Power shouldnt be too much of a problem depending on the screen (mine takes 12v dc) But some take mains and drop it down internally which could be a little more problematic.
how much roughly are they on ebay? i bought one from a site specialising in mini itx stuff a while ago and it arrived today. the link is lost with the old forum though unfortunatley. cant even remember what it cost me, i will have a look and see if i can dig out the link.
