This is my new invention:
Fartlights!
It's used to show other people the status of a doorlock.
If the door is locked, the fartlight switches to red and plays a random farting sound.
Beside that, it altough shows a counter since when the door is locked.
This is only the case, to hold old the electronic parts.
If you are interested in building your own. I've added the schematics above.
