Experienced circuit bender David Cranmer has created this noisy but compelling hurdy gurdy out of a batch of four skinned Furbies. The interface is particularly interesting, since it gives a completely human and analog tempo control to the beasts.

Be forewarned that the creatures don't seem to enjoy their new lives very much, and I wonder what they did to deserve such torment. At the time of this writing, the device was up for sale on Ebay, so you could just ask the poor little devils yourself: Ebay auction.

The Ganzbot is a simple robot which can read your twitter feeds (or theoretically, somebody else's I suppose). This little robot is based on some RC servos, and an Arduino, and even comes with source code for the (cough) java interface to control it.

Looks like a nice simple weekend project, no? Video after the jump!
