This weekends project, turn a creepy looking doll into an interactive Halloween prop!
First step, remove the head and attach a motor.
Two options were considered, a stepper (above) and a servo. I wanted the head to be able to turn 360 degrees but the stepper motor was too slow. Even though the servo can only rotate 180 degrees, the speed is good and it was also easier to attach so this is what I decided upon.
With the head back in the dolls body (thanks to a lot of hot glue!) it’s time to test, next up will be programming some sort of routine and maybe add some additional theatrics…
Adding a strobe using a transistor and animating specific moves…
