Simple to build and fun to use, students can choose the cricket sound they find most irritating to spook parents, siblings, friends, or their favorite teacher! This electronic cricket starts chirping when the lights go out. If you turn the lights on to look for it, it will go silent again. The cricket uses a CMOS IC and CDS cell circuit with adjustable sound control. Designed for beginners, this kit requires soldering components to the PC board while building.
