For Christmas, I hacked my wife’s Jim Bauer robot sculpture. It had a red plastic heart that flickered when switched on. The bulb had burned out, and it would have been easy enough to replace, but why do that when I could make it better?
I replaced the candelabra bulb inside the robot with a ThingM BlinkM MaxM, printed a new heart on the MakerBot, and used an Arduino to drive the whole thing. By hooking it up to a Asus WL-520gU Wi-Fi router, I can control it over Wi-Fi.
The Wi-Fi part was the complicated part, but fortunately Todbot figured it out already, so I was able to rely on his excellent blog post.
