Talkie Walkie with Arduino.

The Lip-sync paper puppet made by martins with Arduino. (http://lab.guilhermemartins.net/2009/05/26/talkie-walkie/) is very cool, it used a sound sensor to capture human voice and only one servo to control the paper lip. The design is simple, but it has a lots of fun ;)

Recently I am studying on servo motors with AVR, one of the basic element of making robots. I am thinking to start a simple project to play around with servo motors, a simpleWalker: 4-legged 2 servo walking robots may be a good choice. The full instructions are on instructables.
