After a hackathon earlier this year, members of the Mikamai team modded an old raggedy (and creepy) doll that was left behind into, well, an even creepier Halloween accessory. The London-based agency used an Atmel ATtiny85, Arduino Yún (ATmega32u4) and a single CR2032 battery to power the toy.
To round out its possessed effect, the team decided to put a pair of red LEDs in place of its existing eyes along with a vibration sensor to turn on the LEDs when someone shakes the doll.
