12/31/12 - Two Out Of Four

This was a last minute Christmas present suggested by most recent flight back from Seattle. The climb out of Boeing Field takes one over an industrial area south of Seattle. It doesn't look like much by day, but there are all sorts of fascinating lights by night. One set was hypnotizing, a set of four columns lighted two at a time, moving about an invisible shape. A quick trip to the Radio Shack provided an Arduino processor and some red LEDs. JoAnn's fabrics and hobby supplies next door provided four plastic columns for supporting elaborate wedding cakes. Add in a glue gun, a soldering iron and some black foam board, and there was something new under the tree. Be sure to click and watch the dark video. It can be hypnotic.
