Worklog [2024 Contest Entry] Xbox Portable: Second Chance

[Redherring32]

Hey folks, as you may remember last year I entered the competition attempting to make a portable Xbox only to crash and burn at the finish line.
Well this year thanks to some awesome rule changes, I am getting a second chance.
I will be entering with the same portable, and attempting to finish it for real this time.
Per the rules I am required to open source prior work to make it a bit more fair for everyone, and I have done just that.

You can find source materials for pre existing PCB designs, as well as some that I have finished since last year here:
Xbox Portable Github repo

The housing design can be found here:
Housing 3D models

Features:

Some of the build is the same, a lot is new and redone, the goal is to include the following features.

• 9" 800x480 display
• Digital video via MakeMHz XboxHD+ for crispy video
• Digital audio via 4Layertech U-AMP 2
• Reverse engineered S controller controls for complete compatibility, as well as socketed Xbox One sticks for solder-free replacement
• 128GBs of MicroSD storage for game loading
• (New!) WiFi for playing Xbox Live enabled games online via Insignia
• (New!) Seamless 100W USB C PD charge and play
• 4x 21700 cells for an estimated 1.5hrs of battery life

Additionally, where there was a lot of hand wiring in the previous build attempt, I have started to replace a lot of that with clean and reliable (Hopefully) flex PCBs, and have/will improve upon nearly every PCB in the build.
So this time it should be much more fleshed out of an entry, and I am pretty excited to get going again on building this beast.



Anyway I guess that's mostly all I wanted to say, and wanna wish the other contestants the best of luck.

Catch ya later.

Do you mean in terms of the case design, or the branding and publicity of it?

Been hard at work since the last post.
Got my WiFi flex designed, got my 100W charge board designed, and I started prepping another motherboard for trimming!

The only thing really left to design is the charge port board, which admittedly is more complex than it sounds, but I am super close to being able to start the long process of putting this thing together.
I do have some "stretch goals" in mind if I finish with enough time left, but it is pretty likely I won't have to use them.

Anyway, will report back when I get a bit more done!

Hello folks, as always I managed to forget to keep up with my thread.
It has been a wild ride, but I am happy to say that this officially my final submission to the competition!

I was not able to get WiFi in, but other than some SD card corruption issues I have gotten everything else I promised in in time.
This project has been a crazy ride, over a year of hell, but I also had fun along the way and learned some new stuff.
After the disaster of last year I can't believe I have finally made it to the finish line, but the day has finally come.

Thank you to everyone that followed along with me here and in the Discord it has meant a lot, and you can bet I'm coming back next year.

Without further ado this is my submission video:

And here's some photos and noods:

Best of luck to everyone else who entered, hopefully we have a better turn out than last year!
