Case for the cheap clock kits available on eBay for about $2.50. The clock kit is a good solder practice item, and this case should cover up the electronics nicely. I'm not working on this any more, but it does still need a bit of work. I ran the clock on 3xAA, and it lasted 2 days, tops. From that, I think running it off batteries is a bad idea. I'd like the case to have a mount for a power supply jack, but don't have time to continue revising the design.v4 (current): v3:
