knewter/kvm-board
An open-source KVM-over-IP device built with a Milk-V Duo S (RISC-V) and ESP32-S3. Remotely control any computer's keyboard, video, and mouse over your network — at the hardware level, independent of the target's OS.

cookiemonsternz/Eurorack-VCO
Also, a lot of eurorack modules are quite bland in terms of design, often lacking any personality and focusing purely on cramming as many knobs in as possible.


mmosko/Zx50
This is the primary CPU board for the Zx50 8-slot passive backplane system. It hosts the Z80 microprocessor (running at 5 MHz to 10 MHz) and acts as the master controller for the primary bus.

It measures 85 × 85 mm and has 4 copper layers, 1.75 mm thick.
123 parts, built around the EP4CE15E22C8N, 74LVC1G17Z, W25Q16JVSNIQ and AMS1117-2.5. 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 SteveLRojas/LandShark repository on GitHub, at the commit this page was made from: the board is LandShark/LandShark.kicad_pcb and its schematic LandShark/LandShark.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
