Affix a RaspberryPi with 801s sensor attached, get paged via PagerDuty when your laundry is done.
Basically, it is fun to play with RaspberryPi's.
Practically, I did this so I can reduce my mental energy remembering that my laundry is in progress. This is at least, somewhat practical since my laundry is in the basement and I always forget about it.
- Connect the 801s sensor to the GPIO pins. I just jammed it in there because the 5v, Ground, and Out pins lined up on the 4, 6 & 8 pins.
 - Configure a PagerDuty API Integration, obtain a service key
 - Run 
PD_SERVICE_KEY=<key> python ./vibration.pyor some other variation of the same command.
