Well, here we go!

• Videos of severial X10 projects are on Vimeo. 
• Photos and some schematics are on Flicker. 
• Project announcements -  search the Arduino forum for "X10"
• Tutorials I've written can be found on the Arduino Playground - for example:
  CM17A "Firecracker" interface for Arduino
  Receiving X10 Commands with the PSC05/TW523
  

As I describe each project I'll include material from these links in addition to new material. As to how well I'll describe each project, that depends on you. Until I get questions, I won't go overboard. However, if I do get questions I will add the detail that covers them.

Welcome! - and I hope you find this interesting and helpful.
