In my previous SPARK post, I created a program that sends serial port commands via an XBee transceiver to control lights plugged into a modified power strip. It was nice to see this level of functionality, but since this is my last SPARK post, I wanted to add a little pizzazz to the project. The eBox 2300 computer I am using has audio in and audio out. I thought it’d be cool if I had lights flashing in coordination with music. The more lights I have, the cooler the effect. So I grabbed several more of my hacked power strips, added some code to the Windows Embedded program, and had a nice little light show sequenced to flash along to Herbie Hancock’s Chameleon.
The power strips happen to be great project enclosures for my line voltage powered electronics.
