* (http://www.opencircuits.com/) — “Open Circuits is a wiki for sharing open source electronics knowledge, schematics, board layouts, ports and parts libraries.”

Don’t forget you can create and use your own “personal wiki” as a lab notebook of sorts using software like Pwyky (http://code.rancidbacon.com/SoftwareNotes#pwyky5) or an online service.

You can use your wiki for everything from tracking useful links (http://code.rancidbacon.com/Electronics) to documenting how you’ve used specific components (http://code.rancidbacon.com/LearningAboutUCC283). Having your own lab notebook can be a useful memory aid (particularly if you tend to have multiple projects on the go at one time ) and useful contribution to the community.
