XP3 Programmable Message Clock

There I was perusing the aisles at a Sharper Image store (as I am wont to do), and came across quite a few cool gadgets. The first one started off as a science experiment of sorts, as there are quite a few write-ups on how it works. It is an LED message generator that uses a wand and takes advantage of a quirk with the way our eyes work – persistence of vision. Essentially, the wand that oscillates back and forth lights up the LEDs on it at the right point in its oscillation to form a complete message. Although the LED wand has moved on from the point at which it flashed part of a character, persistence of vision means that we continue to ‘see it’ even though the wand is no longer at that position in space.

That may not be the best explanation, but trust me – the end result is very cool. You can pick up a practical use of this technology in the form of a clock that can also be programmed to display messages, the XP3 Programmable Message Clock.

Features:

• Super-cool message clock features amazing new technology that creates an image that appears to float in mid-air.
• Pre-programmed daily and year-round greetings are automatically displayed.
• You can even program four personal messages using up to 200 characters each!
• The quartz-accurate clock with automatic DST adjustment maintains date and time during power disruptions.
• Dimming control lets you adjust the brightness.
