Worklog PS4 Slim Portable

[Lecisco]

Hi, this is my second attempt to create a PS4 Portable.

My first attempt was a PS4 FAT Portable with a seperate gamepad.
It was just a PS4 on Lithium batteries with a screen. But 12V with 13A gave just one hour of gameplay with a 3S4P of 18650 (3500 mah each cell) so i really prefered to play it with a power input.
Here is a photo:

My new project is now to do a PS4 Slim Portable with a gamepad inside and a 3S4P of 21700 (5000 mAh each cell)
Thanks to the Ashida Wii project, i feel more confident to make my new project.

The 3D Front part: (made with Tinkercad)

In reality: (FDM printed with PLA+)

Schematics of the PS4 gamepad :

And almost all wired:

But... I connect the new wired gamepad to a PS4 and even a Windows PC and I realise that i have a problem with L2 and R2 !
L2 and R2 is doing like a rapid fire alltime !!!
When I check an official gamepad i realise that the contact are strange for L2 and R2
When i check with a multimeter, it's like the points are connected even if you don't press the button with some kind of a resistor (7K ohm) or a capacitor (125n farad)

Here is a photo:

So i need help. Perhaps one of you have already made a modern gamepad with that problem and found a solution ?

I just realised that in the panel of usb configurator gamepad on windows. L2 and R2 are blinked when it's not pressed and are ON when i press the button
I will try tomerrow to add a 7k resistor between L2- and L2+ or a capacitor of 100nF (i have not a 125nF)

Stay tuned

Yeah it's morning time, i wake up and rushed to test this and.. it WORKS !
So to make L2 working we have to put a resistor of 7K5 (7500 ohms) between L2- and L2+ and between L2+ and L1+
To make R2 working we have to put a resistor of 7K5 (7500 ohms) between R2- and R2+ and between R2+ and R1+

I got at first a pbm because i had not soldered at the same side R1-R1+ R2+R2- .. it was inverted and the R2 was always connected and disconnected only when R1 was pressed :p it was crazy .. having the same color for + and - was not a good idea ZzzzZZzzzz

This is pretty cool! Good job man.

Trim the metal case to decrease size without cutting the mother board:
Size of the motherboard ps4 slim: 247mm 142mm
I keep the metal case and put fresh pads for the ram and new thermal paste

I build a little case and cover with aluminium foil + capton and I add a probe to check temperature

56°C in game for about 15mn in gaming

I built the battery 3S4P and will use a BMS 3S 40A and an active balancer that can be ON/OFF with a little switch

 

[Lecisco]

In Game we use 6A to 6.5A max (the Game is Destiny 2) for 12V
The home menu it's 4A.

To close the case i will use thin sheets of metal

I will post soon a video (in one week)

After 2 days of gaming the battery life is 2h and the charging time is 2h30 at 60 watts (3S4P - 20000 mAh - 21700 10.5A cells)
The PS4 switch off at 9.7V~9.8V (3.26v for each lithium cell so they are far to be emptied (2.5v))
The power delivery module inside the "PS4 Portable" is really hot at 60 watts but the plastic PTFE is not melting thanksfully.
My powerdelivery brandnamed GREEN has 4 ports: 2 for 100 watts and 2 for 25 watts.
The 25 watts provide in fact 20 watts with my PD module, it's not warm at all and it's a better choice to charge the lithium battery without decrease the battery life but the charging time is around 8h.
It's heavy and not really fun to play because of the weight so it's better to play it on a stand or lying down in your bed and stand it on your belly ^o^
I have added a module to modify the speed of the CPU/GPU fan made by "Circuit Surgery" who sell it on ebay from Great Britain

Very cool build! 2 hours of runtime is impressive.

I'm curious, where is the battery charger? I only see the PD controller, protection circuit, and balancer.

Edit: nevermind, looks like the PD controller is an IP2368 charger module? Good choice

@YveltalGriffin
If you mean the battery pack, it is beneath the RED TABLE, the cells are in pink color

I have not added it but it's still possible to add on the switch ON/OFF a link to the real ps4 charger thanks to a XT60 just for the line 12V because it s linked to the 5v module for the standby mode (it's the little green scare near the active balancer module)
You can also play with the power delivery but at 60watts it's not enough because the ps4 slim use about 76 watts

@YveltalGriffin yes it's a IP2368 charger module for 2S to 6S
You have to change SMD resistors for choosing 3S (sold 4S) , 4.15V for each cells (sold 4.2V) and the max capacity to 20000mAh
R7= 9.1k for 3S
R5= 24.9k for 20000 mAh
R2= 7.5k for 4.15V
