Description
To some cultures the presence of a cricket is said to be good luck. To others it is an annoying, intrusive inset. 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 will stops the “cricket” when it is exposed to light…. then hide the module in a dark location and enjoy the fun as people search for the source of the sound .
