Magic LED ball with Bluetooth and position awareness
LED balls are amazing. Building them is quite time consuming but the effect pays off. Null Space Labs have built a great LED ball prototype which is pretty ambitious. The ball is assembled out of sixteen PCB slices with 24 LEDs on each of it. All slices are identical PCBs but only one has master ATMega328 microcontroller that controlls other slices with LEDs. There is a Bluetooth module that accepts data to perform effects and animations. Additionally there is an accelerometer which allows detecting current ball position or movement for better interactivity. A microphone connected to ADC channel can be used to sync ball with music. So there are lots of uses of this fantastic Blinky ball....
