The T.O.W.S. (Terribly Obnoxious Woodpecker Sound) Kit produces a very loud woodpecker sound. This small kit just can't be ignored as it generates the pecking sound of a crazed bird. Uses a small piezo and a two transistor electronic circuit that generates a high voltage to provide a terribly loud "rapping/tapping" sound from the piezo. Features include a small control to adjust the speed of the "Tapping", and operation from a 9V battery (not included). Size of PC board: 2-3/4" x 1-3/8". Complete with all parts, PC board and instructions. Skill Level 1. This kit requires soldering of components to the PC board while building.
