The WeaPEN

This little electronic project will wipe procrastination from the face of the earth, once and for all. The top of the pen contains a 555 timer circuit soldered to a pressure sensor. When the pen is in use, the compressed pressure sensor continually resets the timer. However, when the pen is left idle for more than 13 seconds, a buzzer is activated, jolting the user out of his unproductive reverie.
