Some of our readers will remember the Thermochromic Urinal that we featured on Geeky Gadgets a while back, now we have the Thermochromic clock which uses similar technology.
The Thermochromic clock was developed by Che-Wei Wang and Taylor Levy of CW&T, and this funky clock is controlled by an Arduino, have a look at the video of it in action below.
Thermochromic Clock is a 4-digit 7-segment timepiece. Each segment in the display is made with a length of nichrome wire and then covered by a thick layer of black thermochromic paint. Time is displayed by applying voltage to the nichrome wire. As the wire sustains an electric current, it heats up the surrounding thermochromic paint, causing it to become transparent.
You can find out more information on how the Thermochromic clock works over at Creative Applications.
