The TOWS (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. Size of PC board: 2 3/4” x 1 3/8”. Complete with all parts, PC board and instructions. Skill Level 1.

Features include a small control to adjust the speed of the “tapping”, and operation from one 9V battery (not included).
