Made as a gift for my girlfriend, as she loves Armin van Buuren, and he's coming to town.

The chinese segment was bought for $4.99 in DX http://dx.com/p/diy8-x-seven-segment-displays-module-for-arduino-595-driver-250813

As the examples were not for Arduino, I made them from scratch. The program sends the desired letter (this module have the common anode) so I send them reversed. Then, the code sends the segment order (what segment will turn on) and then turn on.

List:

ATTiny85
3.7v 250mAh LiPo battery (obtained from a cheap mp3 player)
7-segment display module
