I wish I had seen that a few weeks ago. I don't have much time to build any more props. But that design is so simple and beats the heck out of the $300 for the rocking granny advertised everywhere this year.
I don have a spare wiper motor. HMMMMMM Maybe have to make some time this weekend.
As always, ScareFX, great stuff! Your website was what inspired me to build my first animatronic over 3 years ago (stirring cauldron witch). My witch is still kicking, and this year she's getting a 5 digital servo treatment in her head.
