ɖҿϝիɟթվ created this project to play arcade games on the Micro:bit:
The Micro:bit is a pretty decent platform for teaching kids to program, but you can’t really make arcade-style games for it. You only have two buttons and a 5×5 display. Perhaps enough for a very small snake game, but that’s pretty much it. That’s why I started working on #PewPew FeatherWing as an alternative platform, but at some point I started wondering if it’s really impossible to do it on the micro:bit.
When the most recent version of micropython got the ability to use any pins for I2C, I realized that I can finally connect a display easily. I could use a HT16K33 and a 8×8 LED matrix like on the PewPew, but I decided to try something else — a monochrome OLED display, similar to the one used on many Arduino-based game consoles.

Community Made: Groboy is a DIY Gaming Handheld Powered by C.H.I.P. Pro
Groboy, created by Groguard, is a C.H.I.P. Pro-powered handheld system designed to run retro console emulators and games on the go.
It’s also a testament to the open source community, readily available data sheets and manufacturing houses, and the tenacity to teach yourself engineering. Groguard, like many of us, is self-taught and pursuing his passion for making through custom projects.
After 4 revisions of the board, Groguard had the design where he wanted it. The custom OSH Park PCB at the heart of Groboy routes signal lines from the 2.8″ TFT display, headphones jack, internal 2500mAh LiPo battery (he estimates 3-5 hours of battery life, though he’s not rigorously tested it), and the PCA9555 I2C GPIO expander, which manages inputs from the 11 onboard buttons, to the respective input and output pins on C.H.I.P. Pro.
moosepr designed this small and simple GameBoy-style device using the Raspberry Pi Zero:
I’m not overly fond of ‘rats nest’ wires, and I have a bit of an obsession with making things as small as possible, so this is what I came up with.
Tis just an ILI9341 screen, a Pi Zero, 2 navi switches (5 way), and a battery (with charge/protect circuit)
has shared the board on OSH Park:
