Connect PSOne LCD Screen to PC

The 7 volt thing should work as long as there is no other reference to ground (case, etc.). I would suggest testing on some other non-expensive equipment first, because I have never tried with anything other than a couple of ic chips.

Get a voltage regulator ic and build a curcuit.

you will fry ur lcd when you connect to your computer, because the psone use the same ground.

just buy the offcial car adaptor, i bought mine for $10 in bestbuy

This may help. Built one my self. except for 5v. you dont need the extra caps just the actual IC the caps are for power smoothing.

(from a standard molex connector in a computer, 12v is yellow, 5v is red)

I would not do this. Although that makes sense, when you connect it to your computer, the data signals will be off by 5v (since the computer has a 0v GND and the display has a 5v GND)

If it wasn't for the two devices being connected, I'd say go for it

I bought a Sony power supply off Ebay for ~$25 shipped.

use the LM317 Variable voltage regulator or MC34063 switching regulator for efficency.

PSone LCD up in smoke

check this out
USE the psone 12V to 7.5 V adapter and powerstrip is needed to change the refresh rate for this to work

This one's even better:

EDIT: Oh yeah, you can forget those resistors too, I believe it's only needed for the PAL version of this screen.
