Thanks for sharing the video Jack. I really like how your controlling that with and Android and IOIO microcontroller. I'm a beginner Android developer and the little IOIO PIC device is really cool. That is a great way of doing a duty cycle on the AC/DC. Here is a nice discussion on the IOIO (yo-yo) board for others that might be interested.
