Very Loud DIY Filament Alarm

Donald Papp developed a simple but loud alarm, "Mister Screamer", that is hanging from your filament and if the filament runs out it triggers a loud alarm.

Key features:

  • If filament is present, nothing happens.
  • If filament runs out, scream your fool head off to alert a nearby operator.
  • Enclosure can be 3D printed
  • Self-contained (no external power or signals)
  • Requires no modifications to the 3D printer to be monitored
  • Electrically simple, and using a minimum of easy to source parts
  • Long battery life, low power usage
  • Easy to turn off when responding to an alarm
