Jenkins-Chair
Dug North writes –

I know you folks love POV projects. Here’s one you may not have considered…a POV spinning chair! Artist Jim Jenkins created a sculpture entitled “The Little Chair”. The chair is mounted on an axle driven by a powerful motor. When the chair spins, an electronic device writes out the message “Sit still”. There is a video of the chair in action.

MiniPOV- An Inexpensive Persistence of Vision – The 3rd generation MiniPOV is perfect for beginners who are looking to learn how to solder, how to program microcontrollers, or make LED blinky toys. Because the programmer is built into the kit, you don’t need a special “microcontroller programmer”. This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).
