The FacelessTech blog builds a homebrew Arduboy in a Gameboy SP shell:
I had already dipped my foot in the world of making homebrew Arduboys but I wanted a bigger screen. I had a look to see what was out there. I had seen a few people had used the SSD1309 2.42″ Screen so I ordered one. I thought I would just hook it up the same way as the last screen I used. I was wrong, The screen was split into 2. I looked to see if anyone else was having the same problem I found this forum post the had the same problems as me. I didn’t have the mentioned BC557(B), 2N3906, BC309B and S8850 But I found that a 2N2222 transistor would work.
With the Gameboy color Retropie AIO build I had a complete Gameboy color to measure from including the PCB but with this one I only had my childhood GBA SP and didn’t fancy taking that apart to measure. Instead I just ordered a GBA SP replacement shell and used photos off the internet as reference. I also could print out the PCB as I went to see how it fitted into the shell. All in all I think I did a good job considering. I also had to order a 0.8mm thick board because that’s what in the GBA SP.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
