Hi all, i have realized perhaps the ultimate mod for the PS5

It's not just a visual mod, it's also an audio mod, and you can control the speed of the ps5 fan

Box inside there is a screen that displays:
- temperature
- you can increase/decrease fan speed
- choose leds effects
- the status of the ps5: in game or on the dashboard or switch off
- The mod play a sound when you start a game, shutdown or switch on the ps5
- you have 3 sounds that are played 001.mp3 002.mp3 003.mp3 and they are in a folder 01/02/03/04/05 ... /99/
Each folder is an audio theme: PSX theme, god of war, gears of war, halo, transformers, mario
You can create your own audio theme and you can choose your audio theme though bluetooth commands


I have called this modz: the FSRU (Fan Speed Regulator Ultimate)
It's powered through the PS5 JST PH 2mm Fan connector .
You don't need a screewdriver to install it, so yeah it's plug n' play !

It has been designed to fit well withthe PS5 Slim but can be installed easily on PS5 Pro but you will need more leds
For the PS5 FAT, you will need more leds too obviously but in the concern of the temperature sensor you will have to make a 5mm hole in the black plastic cover to make it touch the ventirad

Inside the box you got:
- an ESP32 Wroom programmed in C++
- Buck converter to take the 12v from the fan jst connector and make the 5V for the ESP32
- DFPlayer mini
- I2C oled screen
- 3 little switches
- some wires
- 1 speaker
- 4 jst connector
- 1 temperature sensor
- 1 SD Card of max 32Go
- usb connector of the ESP32 to update it
I have realized the PCB with EAsyEDA and ordered it thanks to JLCPCB

The ESP32 will check on the GPIO33 the voltage of the PS5 PWM
When you are on the Dash it's 0.150 to 0.200V
When you are in game it's 0.5-0.6V
When the ps5 is shutdown it's 0V

Yeap it's great to know that because you can now know easily the status and create audio events !

I will post a video soon
 
This is really cool! Great work!
 
I updated the FSRU2 with a new tactile color display of 2.4"
It display more like, your gamertag, the cover and the name of the gamed played thanks to Lanyard on discord
Lanyard is a service that display your current activity with name and the cover you are playing on PSN (ps5 and ps4) on xbox (360, one and series)

It works on PS5 and even on PS4 pro (the share both the same JST PH connector)

On a regular ps5 or ps4-pro the game played is displayed thanks to Lanyard on Discord but on a jailbroken it's displayed through a connexion on FTP and check if a CUSAxxxxx or a PPSAxxxxx folder is appeared in /mnt/sandbox/
The name and the cover are displayed through the search ID on https://orbispatches.com/CUSA17722 or https://prosperopatches.com/PPSA21564
Every game can have a setting for a particular fan % and color or particular scrolling leds animation

Now the video:
