Qeteshpony/Flipdot-Controller
Replacement controller for a Lawo Luminator Flipdot Display



Ardumower/ardumower
Develop an open source robotic lawn mower (HW+SW reference platform)

tebl/BulkyMIDI-32
A HW build of the MT32-PI project, allowing you to emulate a Roland MT-32 using a Raspberry Pi. Includes enough additional modules to build a MIDI-mountain as well as adapters for connecting to most things retro.

Big-Red-Sat/Perovskite-Curve-Tracer
This repository contains the source hardware and software files for a passive, solar cell, curve tracer.

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
32 parts, built around the R-78E5.0-0.5, UDN2981A-T, CD4514BM and ULN2803A. 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 CatoLynx/LAWO-Arduino repository on GitHub, at the commit this page was made from: the board is Eigene Steuerplatine Line Decoder.kicad_pcb and its schematic Eigene Steuerplatine Line Decoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask CatoLynx before reusing the design.
