Servo control board!

Here’s a circuit board I designed for robots and animatronics. It’s an AVR chip with the Arduino firmware flashed onto it. It has eight servo hookups on it, and a handful of analog and digital inputs. It’s tiny and reliable. I’ll be using it as the motherboard for this project. You may know it as the Twitchie.

In this image is the battery compartment, two servos, a potentiometer with a wad of red duct tape on it and the circuit board. Just in case you’re wondering, it’s running at 16MHz, has voltage regulation for the chip, direct power connections between the servos and the battery case (servos like a few more volts than microcontrollers to really get them going) and is clad in a very dashing shiny black solder mask.

    I’m thinking of placing something like this inside a puppet’s head for eyes that blink. I’d like to know what the cost of this is and if you have a favorite supplier (online) that I could view?
