Worklog Benge BS2 Portable PS2

[Benge]

Hello, after my first great experience in the portabilization of console (O-Wii), I really want to make a portable PS2 !
So here is my worklog

Here are the ideas that I think to integrate :
Custom buttons PCBs with PS2+ on it + RGB led, power button, L1 + R1 (and maybe U-Amp on one side).
PS vita buttons and joy-con joystick
Kingston USB adapter
5.6 inch 4:3 screen
ZYPDS PD USB-C module
PS2 PMS
4 x NCR18650B or 2x 5000 mAh Li-Po
Very thin mackbook fan and I need to found good heat sink, I'm pretty confident on this side @Gman told me that the ps2 was heating up a little less than the Wii.

I have a slim model 79003 PS2 Slim thanks to my spanish friends @KaitoTV , thank you very much !

I have found a Free McBoot 64mb memory card on Ebay for 10€

For now, I am waiting for a PS2 Controller (5€ + 5€ shipping), to test if all work and install all I need on µSD card.
I have found a dead PS vita for 15 € + 5€ shipping, I would try to repair it, I think especially to use it to have the dimensions of the buttons and the space between each other.

Then I could trim the motherboard (advanced trim of course !)
After that I could model it in 3d (if someone already has the files it would help me a lot) to be able to have an idea of the space it takes and how I will organize my case and the PCBs I will create.

While waiting for all of that I have already started to make a first design on paper to have an idea of the real dimensions and to see a little bit the placement of each component in order to choose them as well as possible.

And for now I am Waiting ...

ps2 advanced trim model: https://bitbuilt.net/forums/index.php?threads/ps2-parts.3905/

I've modelled the PS2 board (advanced trim) and the free mcboot card. Both are in the link A-s6 posted.
ill be adding a Raspberry pi both both fully poputaled with components and with the components i plan to remove for my own PS2 build

For now, I have tested 2 screen One 7" 1280x720 16:9 and a 5.6" 4:3 640x480 :
I really don't know which screen to use, the 7 "has a better picture but the 4: 3 is narrower

And yesterday I have Trimmed my PS2 and her the result :

I think I can trim it more, and remove some component, I am going to make question thread about that.

 

[Benge]

Last Night I have trimmed the board much smaller, a little like the Gman's GS2.

Her the result with all wire solder on it (color is the same as the guide) :

And the other face :

I just tested and unfortunately it does not work, the circuits heat up (I think the PS2 boot ? ), but nothing in video output ...

This is the voltage I have measured :
3.33V
2.44V
1.79V
1.23V

Do you have any idea why it doesn't show the bootscreen ?
Voltage ?
Other ?

I'm pretty sure you still need to connect 5v to the ps2

 

[thedrew]

I'm pretty sure you still need to connect 5v to the ps2

Correct. You need to connect 5v to the AV chip, which oddly is not mentioned in the guide but necessary for video. I don't have my multimeter handy, but I believe it's right here that you need to connect 5v to. This whole trace is 5v I believe:

 

[Benge]

Thank you for your help @Anthony Stewart @thedrew .
I will test this this afternoon

 

[Customledmods]

Missing 5v here

 

[Benge]

IT WORK !!!!
Thank you for your help guys

Now I will model the PS2 trim in fusion 360 and start the design of the case.

 

[destroyer12]

Great work so far! I'm looking at building a ps2 portable myself. Where did you get that 7" screen?

Edit: What extra were you able to trim off the motherboard?

 

[Gman]

What gauge wire is that? You should be using 22awg for the 1.25v and ground, there is significant current here and can result in voltage drop if thinner wire is used.

It is AWG 24 I think, thanks for this point of course it is just for testing now, it is not the definitive wire
I think of using 22 or 20 AWG with Teflon insulation (reuse wire, not buy because it is very expensive lol ).

I have made some progress in the idea of design for my Portable PS2.
I think to use 6,5" screen, the 7" look to big, and I don't like the 4:3.
And for the battery I am going for two 5000 mAh LiPo of 75x55x10 mm, thank you, @Gman, for helping me with this part !

Here is the idea :

And for now I have replaced the fat LM317 by this tiny TPS73618 LDO for the 1.8V reg.
It is a little dirty, but it is stable (just tested the voltage output, not tested with ps2 yet) :

Tomorrow I will continue my custom controller PCBs, yes I didn't tell you about that now.
I will show you the result soon

that is amazing; good work man! I am curious though, did you make the regulator board by hand( not the parts but the PCB itself) or did you purchase it from somewhere(ive been trying to avoid making custom PCBs as that is alot of money that i don't have XD)

Hello, I have ordered the PCB on JLCPCB and place all the component by hand.


The advancement of the Portable PS2 :

I am designing pcbs for buttons and joysticks, but I have a question :
Is the length of the signal tracks of the "controller" is important or need to be same ?
Because on my PCB it is not the same lenght at all ...

 

[Stitches]

AFAIK the trace length doesn't matter

 

[Benge]

Hello guys !

I made a lot of progress on my portable PS2, and also made some mistakes ...

First I finished the PCBs and this is what they look like :

@Stitches I still put the signal tracks of the same lenght, I saw that it was easy to do, at least I'm sure not to have any problems.
However I made a big mistake ... I put a gap of 15 cm instead of 13 cm between the centers of the buttons for the directional cross PCB (I was 200% sure that I put 13 but no ... yes I fucked up) and the PCBs are already sent from JLCPCB (Thanks @Gman for the discount code !), so for repair this I will need to use hot glue and magnet wire.

I still have plenty other thing to show you, I'll post this tomorrow

 

[Benge]

Good evening, or good morning, as promised here is the rest of the advancement !

Test print Time :
After about 1 billion test prints my PS vita buttons fit pretty well, I had struggle a lot with them

After that I printed some tests for the part with the kingston adapter and the PD activator module in USB-C for charging,
and it fit nice at the second print

I did another test too, to come

Tomorrow I will show you the modeling with the final rendering that my portable PS2 should have

thats awesome man, it looks really professional as it is. I cant wait to see what the beauty will look like when its finished
