Just finished mine this weekend. Took quite a bit longer than I thought it would, but projects always do. Told SWMBO I'd be working on this for about an hour or so, but shopping + wiring took me about 5.5 hours hehe. Here it is!
To be fair, the last hour or so was me fretting the cooling power supply wasn't working (thus, disassembling and testing), but it turns out I'm a moron and I forgot that the cycle delay stopped the cooling outlet from being powered until the set-time passed. Doh! Works fine and I need to retract my email to mixtea :/
8x6x3 box from RadioShack, with the outlet in the back. Very basic build, no indicator lamps or anything. I don't really see the point when the STC1000 already displays when it's heating or cooling. I'm most pleased about the rubber grommets around the cables as they exit the box... make everything look professional and fancy! Power cable goes out the back (which you can't see), and that's the temperature probe in the lower left of the photo.
Making one of these is like a rite of passage for a brewer. Happy to join y'all!
