Raspberry Pi Magnetic- Driven Ouija Board Can Spell Words Automatically

A Raspberry Pi engineer shared their homemade project OuijaCNC: using 3D-printed parts, fishing line, motors, and an ESP32, they built a Core XY CNC mechanism that drives the Ouija board planchette via magnets beneath a wooden board, moving it to designated letters. The system is run by a Raspberry Pi 3 Model B+ running Raspberry Pi OS Trixie; a Python Flask web interface converts input text into G-code, which is sent over a USB serial connection to the ESP32 to drive the motors. Currently the device still requires a person to listen to questions and enter answers into the web interface; it cannot understand questions on its own. The author says they are considering later adding a microphone and an AI model to parse questions and generate replies.
