Fun to Build & Hack

The MONOCHRON is a completely hackable, open source, clock kit that has a funky retro feel. It can be programmed to display several different clock "faces" or you can program you own. The kit comes complete with all electronics (soldering required), laser cut case, and power plug.

Note: You'll need some basic soldering & hand tools to assemble the MONOCHRON. The good news is that this is a pretty basic kit and even if it's your first soldering project, it shouldn't take more than 2 or 3 hours to put together. If you'd like to get an idea of how easy it is to build check out the creator's website to get an idea of how it's made!
