From MAKE subscriber Justin Shaw comes the UberLight - a dual LED matrix bicycle turn signal an brake light. An interesting design using accelerometer to determine braking, plus basic switches for indicating turns. The project uses an Arduino in combination with a couple of serial-controlled red/green matrices. Riding with this setup should get some much-needed attention from nighttime drivers. For more info, check out the schematic and source code.
