Welcome to Open Circuits. Open Circuits is a wiki for sharing electronics knowledge, schematics, board layouts, and parts libraries.

wiki-nodes of neighboring wiki

The WikiNode project tries to link every wiki in the world together. Our "WikiNode" links to closely-related wiki (and their WikiNode links back).

If you want to talk about something that is not quite on-topic here at Open Circuits (say, "desktop PC case modding", or "embedded Linux programming"), our WikiNode helps you find another wiki where people love to talk about that exact topic. The corresponding WikiNode on each of those wiki helps people who want to talk about "open hardware" to discover this wiki.

We briefly touch on computer architecture on a few Open Circuits pages. ( Kestrel, Multi-purpose Embedded System, relay CPU ). For far more details, see other wiki such as

vehicles and robots and CNC

  • the RepRap wiki discusses the RepRap project to build a "Replicating Rapid-prototyper", a self-copying 3D printer. "Complete open-source instructions and plans are published on this website for zero cost and available to everyone so, if you want to make one yourself, you can."
  • EV production wiki discusses several electric open source vehicles.
  • OpenServo wiki -- developing a digital servo motor that accepts "Go to position X" commands and also more complex curves, and returns actual servo position, speed, voltage and power consumption.
  • Robotics wiki (offline as of 2007-07-07)
  • the wiki describes an open-source CNC machine -- software, electronics, motors, hardware, etc. -- and related information, such as CNC PCB milling. (was: [2] ) needs WikiNode
  • VEMS wiki has some interesting electronics projects. In particular, the GoBox project to tune automobile engines to minimize the amount of fuel used. needs wikinode
  • JMRI wiki ( ) The JMRI project is building tools for model railroad computer control.
  • the DCC wiki ( ) ("Digital Command Control") discusses computer-controlled model railroads.
  • the wiki: discusses open source benchtop tools, laser cutters, and electronics DIY/hobbyists. needs wikinode
  • the EcoModder wiki discusses various ways to measure and improve vehicle gas economy, including "MPGuino is an open source fuel economy computer (Arduino based) for any vehicle with electronic fuel injection and a Vehicle Speed Sensor."
  • MakerBot Wiki

  • dorkbot: Artists, inventors, scientists, engineers. The exciting thing to me is to learn about strange things that creative people are doing around the world, with no regard for genre, style, school of thought, area of expertise, etc. ... committed to the idea of "availability over promotion", meaning their main concern is to help things exist, rather than making hits or selling lots of copies.
