Keeping Atomic Time: Projection Clocks
By Charles Wilkinson

If you've ever watched Star Wars, you'll remember how R2-D2 projects a holographic image of Princess Leia begging Obi-Wan Kenobi for help. Alas, we're not quite up to creating holographic images quite yet today, but if you're a sci-fi fan and/or a fan of gadgets and new technology, you can get a projection clock for your home!

The projection clock is a timekeeping piece that usually has a conventional LCD display but also shoots out a beam of light that will project the time onto any flat surface, such as a wall or ceiling, just like a projection TV would. This is not what makes the projection clock unique however; what makes it unique is atomic time!

The Most Accurate Clock in the World

Most projection clocks are linked to the U.S. Atomic Clock, and atomic clocks are the most accurate clocks in the world. The U.S. clock's designation is the NIST-F1 Cesium Fountain Atomic Clock, and in conjunction with other atomic clocks from around the world, it helps set the official world time (UTC). According to the NIST-F1's official website, the time should not fluctuate for the next 60 million years.

This is important for a number of reasons including keeping GPS co-ordinates accurate and in maintaining satellites and so forth. In other words, with your projection clock linked to the U.S. Atomic Clock, you will have one of the most accurate timepieces ever. Let's take a look at a few of the models available!

Form vs. Function

The Sharper Image has a nice projection alarm clock available that is quite stylish compared to most other models, but it is quite pricey at around a hundred dollars. It has a thin silver body, with a nice blue LCD face and control buttons that are well-designed. It comes with a thermometer and can be set to a silent vibrating mode if you want to put it under your pillow, and it comes with their Sound Soother system (six selections to choose from) that will help you get to sleep in the first place.

If you're looking for something cheaper and just want something purely functional, try a model like a La Crosse Technology projection alarm clock. If you can find a closeout deal, some models may be available for around $17. Also consider Oregon Scientific for low to mid-range offerings that are fairly stylish as well. Their RRM968PA and RM888PA have an interesting, sleek technological look that might suit you.

Just for fun, you might be able to find a HIDEKI PC06 clock. You might not believe this, but it a baseball-shaped projection clock! It would be a nice gift for a baseball fan and is relatively cheap. Hopefully, this helps on your hunt for the perfect projection clock. Good luck!
