Maker Faire Austin 2008
Ceiling Fan Sign

It is a 5 blade ceiling fan with LEDs mounted vertically on the end of the blades. It scrolls a message 360 degrees above the tips of the blades. The message is input using a computer keyboard plugged into a radio transmitter. It is a mono color display. I use a C8051F364 to control the LEDs. The microcontroller was designed by Silicon Laboratories in Austin, TX.
