This beautifully designed solder kit will sound like a real-life cicada once it's dark! The entire kit consists out of three parts: the body and two wings. This way, the cicada has an extra dimension and resembles a real cicada (but bigger). Other components include a buzzer to reproduce the crepitating sound, and a phototransistor to make the buzzer go off when it's dark. The gadget is powered by a 9V batter (not included), which make this little bug stand alone. Enjoy making this rather challenging gadget!
