A little scary toy.
Based on an idea from here: https://www.az-delivery.de/blogs/azdelivery-blog-fur-arduino-und-raspberry-pi/halloween-2022-der-suessigkeitenwaechter
Software is based on a miniature board using ESP8266 which I developed myself. Any other microcontroller would do, but my code might use some minor changes. To make your own board, here are schematics and Gerber files: https://github.com/Pontifex42/UniMiniESP8266 Not all components have to be populated, many parts are optional.
Some more information to build it is on thingiverse: https://www.thingiverse.com/thing:5584885
Mp3 samples are for mp3 player like DFPlayer. Some mp3 snippets are omitted due to legal reasons, I took them from a song "Nina Hagen - Auf'm Friedhof". Feel free to place your own samples (< 10 seconds), the filename scheme is obvious.
