I made this ChronoBlot a while back, but now that I have a BusPirate, I can easily test it out, set the clock, and set the alarm (and write scripts to help with that), so I'll be updating it soon and wanted to track it on this projects forum (which I prefer to a blog; the discussion seems better).

It's a DIY-remake of the ChronoDot (first version), by MaceTech ( http://www.macetech.com/blog/node/99 (http://www.macetech.com/blog/node/99) ). You can see more of my attempts at toner-transferring the silkscreen layer (which turned out pretty poorly in this case).
