There’s a Class 100 semiconductor cleanroom inside this backyard shed. YouTube video by Dr.Semiconductor

This guy built a semiconductor lab in a shed, absolutely insane, instant susbscribe www.youtube.com/watch?v=HfSO...

As part of a collaboration with the incredibly talented @redherring32.com of Opentendo fame, we are happy to announce the OpenTendo-AGB (OpenGBA)! This is a fully open source recreation of the AGB-CPU-01 circuit board.

🚀 what did you choose as a replacement, are you self-hosting or using something like proton?

For the protocol nerds out there, I managed to get the target response time (time between message being received from a console, and us sending the reply) down to ~3us on the Pi Pico backend. This is *very* close to the ASIC's response time in OEM controllers.

Looking forward to seeing what people build with this! If you make something, let me know!

This allowed me to do cool things like getting carried away and writing a full protocol-identical reimplementation of the official GameCube controller USB adapter on a Pi Pico:
github.com/loopj/libjoy...

The Pi Pico implementation is written from scratch using PIO and fits in a single state machine, so theoretically can support 8 simultaneous buses on a Pi Pico, or 12 (!) on a Pi Pico 2.

This was initially extracted from the WavePhoenix project with the goal of being more broadly usable. This library supports "host mode", aka acting as an N64 or GameCube console and communicating with a controller, as well as "target mode" aka emulating a controller on the joybus.

👋 just released the first public version of libjoybus, an open implementation of the Nintendo Joybus protocol used by N64 and GameCube controllers, with initial support for Pi Pico (1 and 2) and SiLabs Gecko microcontrollers: github.com/loopj/libjoy...

I've finalised and released my Asrock BC-250 case, with multiple designs to hopefully tickle your fancy.

Thanks for all your efforts on this project dude!

And they tried to tell me it shouldn’t be done! But behold! The #Cuboid!
It’s rocking both the GCLoader and the Dual. And also, it’s shorter!

A flex PCB with concentric copper rings and perforations so it can be torn into smaller arcs and wedges.

The same flex PCB with one quarter of it torn out and turned into three curved connector pieces of different radii. The remaining board has a silkscreen that says "Do it [...] coward" in Jokerman font.

A silly idea that turned out well! Most flex PCBs are cut by laser, not milled, so you can make perforations by adding incomplete edge cuts. These disks are for cleanly joining LED strips at different angles and different radii, and they break apart with just my fingers, no other tools.

Here's a quick hands-on overview of the Raspberry Pi CM0, a 39x33mm RP3A0 castellated compute module @raspberrypi.com and EDATEC have released exclusively for the Chinese market!

Hey everyone! Today at 11am EST I will be Premiering a video that's been nearly one year in the making. I worked with some amazing modders and @pcbwayofficial.bsky.social to make this Project a reality and I really hope you all enjoy it!

I've created a 3D model for the Sony A14/D14 BVM Bezel. If printed it should fit 1:1 with the stock unit.

This is some of the hardest shit I've seen in my life

*cracks knuckles*

okay so you know how the media has a problem with taking snippets of scientific studies out of context and writing articles which mislead the public?

now imagine a computer program is doing that when you ask it questions about scientific literature but also it makes stuff up.

i reverse-engineered the Raspberry Pi Compute Module 5! check it out at github.com/schlae/cm5-r...

Allison has made a Game Boy cart based around the RP2040. The RP2040 acts as a MBC!
The documentation is freaking fantastic and Allison has released the files under the CC BY-NC-SA license

This is straight fire

you have to fill it completely with transparent resin once you are done or else

If we can lobby GitHub to allow the KiCanvas embed on READMEs that would be my dream.

KiCanvas is such a dope project (kicanvas.org), shout out to @thea.codes.

OpenOCD such a great tool but the development really is a hot mess. It is relied upon by so many projects, but still hosted on SOURCEFORGE. Every vendor is maintaining their own fork and nothing seems to get upstreamed. I don't know who the core maintainers are, but something has to change.

I'm stoked to have finally finished the Kawaii, a fully functional metal Wii keychain. It's way smaller than it looks— only as big as a Game Boy cartridge! ✨🟦✨

Huge thanks to @weskmods.bsky.social and @dingding-cnc.bsky.social for being awesome project partners!

The Nintendo Kawaii, a collaboration project between myself, @mks.bsky.social and @dingding-cnc.bsky.social has finally been released fully open source!

If you're brave enough to build one you'll have one of the most unique pieces of gaming jewellery ever.
