If you want to drive the guys over at Open Picus nuts send a tweet to their dancing santa! Check out their Open Picus Dancing Twitter Santa project to see how they connected the santa with a few bits of electronics to their system. I have a feeling that this will be a fun gadget on the desk until it keeps dancing non stop for a few hours…
“I have a Santa Claus that lights up and moves when you turn on its switch. So bypassing the switch, you can build a virtual switch with an NPN transistor. The base is controlled by the signal coming from the “out2″ of Flyport with a resistor to limit the base current. Our Santa Claus, it’s like an active load between the collector and VDD (2 AA batteries) and the emitter to ground (GND) shared by Flyport and Santa Claus.”
