An Arduino-controlled puppet with moving eyes and mouth.
Jeff Kessler originally made TJ* to use in a short movie he was making before deciding to develop it for the public. TJ* is an animatronic puppet head with eyes the move up, down, left, and right as well as a moving mouth.
It is intended as both a toy for children that they can continue to improve as they grow up and as a development platform for makers and artists.
The complete system is still available for pre-order on Kickstarter for $120, but if already have an Arduino you can pre-order just the head and servo motors for $50.
