To some cultures the presence of a cricket is said to be good luck. To others it is an annoying, intrusive insect. The FK270 utilizes op-amps to mimic the sound of a cricket. Hobbyists and students will see immediately that the same circuit can be used to play an amusing joke. Add a photo transistor that when the "cricket" is exposed to light the sound stops. Then push the cricket under a bed or other furniture and watch the fun when people start looking for the source of voice.
