Ok so far we can remove the Top and bottom part of the PSone screen and LED mod it. Has anyone attempted to remove the two wings? There looks to be some mission critical components there but I think it pertains to the audio amp (which im replacing cause I want an analog knob for volume).
Also to minimize the power usage I am going to replace the 7805's on the back with a single switching regulator. Those linear regulators are roughly running at 60% eff and replacing them will boost the eff rating to 85-90%.
I recall reading that only a certain part of the screen uses the 7.4V? What was that...hmm

Re: Maximizing the PSone
The inverter at the top is the only part that takes 7.4V. Take a look at that guide I made . The 7.4V in spot looks like it goes through some kind of small linear regulator. Also, I added some thoughts on removing the sides to that sticky. But I think anyone has yet to find it.
EDIT: I was just looking at those pictures, and noticed several places labeled VDD connected to a few of those regulators.

Well just replacing the twin 7805's on the back and LED modding the screen (8 LEDs) the psone screen uses about 290mAh with no sound going through it. A drop of about 100mAh? I will take it!

Zenloc reduced the screen board to be smaller than the lcd and did something innovative with the audio amp as well with his GCmini.

Looks like I got more work to do.

Damn! No kidding...
Re: Maximizing the PSone
Yeah I made the screen quite small. But to make it work properly you have to have it run from two different 7805 regulators. One for the audio chip and another one for the rest of the board. If you cut the audio off and rewire it and don't use a seperate 7805 source then it will distort the image on high pitch sounds. Segasonicfan I think also found this out when he was busy with his ps2 portable.
I will be posting a cutting guide very soon. I'll be showing detaild pics of a PAL and NTSC board and where to cut them to make it as small as possible including where to rewire what.
But all of the info is already spreadout on this forum so if you search you'll be able to find what you need. Or you can just wait for my guide
