No-tifier

For the Stupid Hackathon 2017, I made a portable wooden rectangle.
Every few minutes, it buzzes briefly to deliver a notification. By
carrying it in your pocket, you can be notified wherever you are, no
matter what you are doing. The medium is the massage.

You can make one yourself! I used an AVR microcontroller and a
scavenged cell phone buzzer driven with a MOSFET. The source code is
stupid-hackathon-simple.
