Electronic
Whoopie Cushion Deux
The
Electronic Whoopie Cushion Deux is the follow-up to
an earlier electronic version of the whopie cushion
gag. This version uses an MC33794 e-field sensor IC,
a specially designed seat cushion sensor, and an MC68HC908QY4
microcontroller to sense when someone sits down or gets
up from a chair. When the presence of a person is sensed,
the device plays a prerecorded sound.
