Another Peltier woodstove fan. Instructables. OKish.  So I bought an EcoFan for a friend and decided that it was a cool concept and built one from scratch. The fan gets its power from a peltier element that is used in reverse, i.e. it is generating electricity from the heat given off from the stove top.  More can be found on the wikipedia article on http://en.wikipedia.org/wiki/Thermoelectric_cooling

Ultimate RGB Propeller Display

Like many I find something extremely satisfying about watching light displays in awe. From bonfire night fireworks to pretty in game graphics and even an RGB.

My propeller clock  + Source

Check out my propeller clock which I have built during my school days. That the display in operation sometimes has gaps depends on the bad camera.

This project is a special kind of circular LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to.
