A Ouija Robot – The MagPi Issue 148 @TheMagPi

The MagPi Magazine (+ HackSpace) Issue 148 features automating a ouija board using an Adafruit Circuit Playground Express, Adafruit Crickit motor board and CircuitPython:

This spooky build reached our attention too late for Halloween, but there are always opportunities to contact the spirit realm. Or maybe just hook it up to ChatGPT and ask it for recipes. Either way, this Ouija Robot by Ronald McCollam is an unusual build, in that it uses both a Raspberry Pi and an Adafruit Crickit board. The reason for this is pretty standard: he had a Crickit to hand, wanted to do something with it, then later realised that it would be good to add the Raspberry Pi to provide a screen to display the messages displayed by the ouija board.

The Ouija Robot takes input from the social media platform formerly known as Twitter, and reads out messages via a robotic hand that moves a piece of plywood with a hole in it over a board (we now know that this smaller board is called a planchette, which sounds very much like French for ‘little plank’) with a laser engraved alphabet.

Other hardware includes a servo for the arm and one for the planchette; two NeoPixels; and a 3.5-inch TFT screen to display the text of the messages received.
