Summary

This is the case for a small IOT capable MP3 Player I use as WIFI doorbell.

The idea is to have one device that listens for the doorbell that sends an UDP broadcast message if a sound is detected and this little guy that plays an MP3 if it receives the message.

Of course you can use if for other purposes as well ;)

FreeCAD source file included!
