piVerified/pi.crystal1A blinker board that is in thw shape of a crystal!
Pi.crystal is an open-source printed circuit board by piVerified, from the piVerified/pi.crystal repository on GitHub, published under the MIT licence. It is a 2-layer board of 53 × 95.1 mm with 7 parts on 9 nets, routed with 23 tracks and 0 vias.
It is built around the ATTINY85-20PU and BAT-HLD-001. Its parts include 2 resistors, 1 IC and 1 diode. It belongs with the AVR (ATmega, ATtiny) boards of this library.

This project would not have been possible without the help of the amazing people of the internet, the Hack Club Stasis Guide, and a bit of AI.
PS: Hugely inspired by @darizone's Firefly kit

krikzz/open-ed
Open-ED is a very simple and cheap open source Genesis/Megadrive cartridge. The cartridge does not have its own processor or FPGA, it is built in the old school style using only memory and discrete logic.

It measures 53 × 95.1 mm and has 2 copper layers, 1.6 mm thick.
7 parts, built around the ATTINY85-20PU and BAT-HLD-001. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the piVerified/pi.crystal repository on GitHub, at the commit this page was made from: the board is PCB/picrystal.kicad_pcb and its schematic PCB/picrystal.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
