A guy named Mark Gibson has put an atomic clock inside a pinball machine, making one of the coolest clocks ever. It’s a WWVB atomic clock using a pinball machine marquee. What used to be the score is now the time, with atomic clock accuracy.

The downside is that it makes a lot of noise. If you want to build one, Mark has detailed instructions for building the atomic pinball clock here. It is a difficult build, but worth it.

Here’s yet another time and temperature device. By now you would think that everyone has this info at their fingertips, but I guess not. The Elements Atomic Projection Alarm Clock with Indoor/Outdoor Thermometer is just what it sounds like.

From Oregon Scientific, this clock will automatically set itself to your location within the US, even making adjustments for Daylight Savings Time without you having to do anything. It also sports a projection feature for night time clock reading fun. It will project details like time, weather and alarm on nearly any surface.
