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.
