A configurable, mutable toddler radio that encourages spelling

song-and-spell

tl;dr

A key-logger that triggers playing an audio track when a sequence of keys are pressed and a web-app to configure the words and songs.

Requires VLC to be installed on the host and an X server to be running.

todo

• key-logger

  • mute
  • upload file
    • remove word/file
  • ~~form add word/link ~~
• systemd service to:

• bash script to deploy (ideally to an [rpi-400]https://www.raspberrypi.org/products/raspberry-pi-400/)

notes

• the pynput library requires an X server to be running. Set default resolution in raspi-config (anything other than default) to force the X server to start.
