PSone screen

JaytheHam · Post by **JaytheHam** » Sun Jan 30, 2005 5:22 pm

Is there a way I can power a Sony PSone screen directly off the N64(which is running off mains power, not batteries) without using any power converty thingies?

with modification to the n64, yes.

A little more detail?

Where exactly should I draw the power from?

the oputput of the 7805 or just from the 12volt line

also, now that I think about it you'll need to modify the n64 power supply too because it doesn't output enough mA to power the n64 and psone screen.

The screen won't operate correctly if I run the 12v line straight into it will it? I read elsewhere on here that it causes the screen to screw up the picture.
What if I took the 12v to the screen through the car adaptor? Would that work fine with no modification at all?

The n64 12v line is just a lable, most people that build a N64p put 7.2v in the 12v line. Now the PSOne screen has 2 7805 power regulators that can take 7+ volts and puts out a steady 5v. So if you have a 7.2v battery you can power the N64 mobo (the 12v line anyways) and the screen easy.

Fine if your just using the AC adapter your going to have to crack it open. Note that the edges are glued and the top of the case has tape securing it to the insides (mine did anyways). You can trace back from the output connector then to the 7812 regulator (I think thats what it is, they dont use standard numbers) and put a wire right on the output, and connect the ground of the PSOne to the gnd of the regulator that all I can think of doing. Keep in mind you'll need to tape the case of the AC adapter back together.

Wrong again...

wait...so the n64 psu can output over 1500mAh on the 12V line?
Checking and it only say 800mAh

I appreciate the help, but I don't know enough about electronics for "trace back from the output connector then to the 7812 regulator" to mean much to me

I took some pictures of the AC adaptor, if anyone could point out what I should do where:

To point out whats the 7012 or likely be, its the IC that is connected to the heatsick by a screw. You should be able to desolder that replace it with one that can handle 2 amps and you'll be set.
