PCBs are working perfectly ! Who wants a slice of 360? With the new PCBs I can remove this part and it works ! 100% on battery so Portable ! Then I analyzed and reconnected all the wires needed to cut out this other part, but after a lot of testing and research no boot. The southbridge is...

If you whant great and not "li-bomb" cels, you can go on this DE website : https://www.akkuteile.de/en The one I used from Aliexpress are fine, but you never really know what you got ...

Here is my last video, I talk about all my attempt : To sum up : 1-NAND Relocation : Thanks to @YveltalGriffin advice, I managed to get the NAND relocation working. The issue was : crossing the wire. For high speed signals the wires must not cross each other, and need to be same lenght...

Glad it could help you on your amazing project ! I really like the design, and the dimensions are really small, can't wait to see what's next :) I really like the mindset of making what many people think impossible possible ;)

You know, Ground vias are very important in PCB design B|

The CPU VCS on my VRM PCB work fine, But my custom VRM didn't work for the moment, So after few test for measuring PWM signal or other signal, I got a things like short circuit at the main voltage for no reason. To see if it comes from my VRM I cut the VRM of a dead MB and put it in place...

Good work, the case is very clean <3

Thanks man :) Yea I will be using a custom heat sink, I have already did some test, but I need to take picture with thermal camera.

It is not 100% of battery, the big VRM that power the XCGPU are powered with the 360 PSU. But it is the next step :)

Xbox 360 is on a diet again ! I receive my custom PCB, so for now the PCB with the "low" power side work great, all regulator are fine. And the circuit that manage the power path and the batterie charging look to be ok (after some difficulties of course). The power ON/OFF latch circuit work...

Oh, pretty nice start ! For your PMS you need to make the switching side area of the regulator inductor the smaller possible and the closest to the circuit (or mosfet). I don't know if you are using a 4 layer board but for the power supply I really recommend it, even if it can go over 2 layers...

Pretty nice if it is smaller than original, and it is also a lot more clean ! With the battery on the back, it can simplify a lot the connection process

Yeeee Here are the planned specs : Thinner than 50 mm (easy, but not possible if I use original controller style shape). 8" IPS <3 Screen 4S 10 000mAh 16.8V lithium battery (maybe li-po or 21700 li-ion) Play time goal : 1 to 2 H USB-C charge and play (100W, 20V 5A) Wifi For now I have finish...

Thank you man ! Here is the video, I corrected the automatic subtitles in French, so I hope the auto translate work well ! I have way too much data to update the thread, so I think I'll do a compilation at the end as a big guide

For the controller, I searched if there is a way to replace it with microcontroller but I saw that there were MS security and that apparently it was not possible. So I'm thinking of using the chip of an original one or a chinese copy one

The big PCB is almost finished, now I have to make another PCB which will contain the other regulators, the charging circuit and the main powering up system. I really don't want to code anything for this project because I suck at coding, and I already have enough headaches with the calculations...

After a very long time of research, reading, learning, and calculations, here is my custom VRM for the XCGPU, 4 phase instead of 2. It's not quite finished, but it's in progress, so if you have any suggestions let me know ;)

I don't know if I can share some screenshot of the shematic of the Xbox 360 because I think it is property of MS ? It can be better to explain. 3 - Use other Better Voltage Regulator ! Some regulators could only have Vin up to 14.5V, and I plan to go up to 20V (I will explain you why later)...

Thanks man, for this very detailed test :) Personally I tried with paint.net and Photoshop, but I quickly gave up because it was doing nonsense, gimp seems to do a much better job ! I will try if I have better result, it can be a huge² time saver. I had also looked for edge detection algorithms...

2 - Voltage Regulator test and research : I removed the GPUPCIE 1.5V LDO reg and replaced with a synchronous one (Wii PSU) After that some glitch appears on the screen. So I replace the LDO, but the console won't boot anymore, and I got a strange very low resistor on this Voltage line. After...
