Hello everyone,

i've been on the forums for over 2 years now, even built a PS2 portable, but I didn't want to post it since it wasn't that good, but i learned a lot along the way, so it's time to improve it.
I'm planning on using ps2 9000x board with custom trim, and video dac relocation, it will be relatively small (117x84mm with stock regulators), but very difficult to solder the dac, and controllers to 0.1mm traces.
OPL will be launched via FORTUNA.

Goals:

- Slim case, 87x185x30mm as of now

- 2 microsd slots, for MX4SIO, and USB to SD adapter for the games not compatible with the first option.

- Two 18650 batteries.

- 5 inch 800x480 screen.

- Original PS2 controller IC

- Switch Joysticks.

I hope it will turn out great :)

Time for an update!

After a lot of issues with my 3d printer( i had to modify extruder from bowden to direct, calibrate it, dry filament, but now it's printing fine)I finally finished first test prints.

And after this pile of junk:

Came out first good prints:

The front case is almost finished. I only have to adjust screw posts height after i get the real PCBs xD.

I've finished last PCBs and tests before the final trim. I was testing if the board works with 5V, but it cuts off at ~5.4V so i will be using 2S battery.
I will only replace 5V linear regulator for a switching regulator.

Also big thanks for @Mister M for posting the board scans.


Here is the board trimmed and working:

and next to untrimmed one:

This trim "only" requires relocating pull up resistors for controllers, memory cards, USB ,soldering to 0.1mm traces and restoring 1 trace for 5V.

And i'ts about the same size as 7900x standard trim (119x99mm).

I also made a microscope for soldering from raspberry pi zero with camera and some lens i had lying around.

I found the 3D model on thingiverse and modified it a little bit:

And it works pretty good. Here is a picture of the video dac traces with a match for scale:

I had to make a photo of the screen, because for some reason photo with raspistill command was zoomed out and screenshot didn't work.

Now i will prepare everything for video relocation before i get the PCBs.
