Square Wave Tone Generator with Light Control


this is a square wave tone generator that puts out a really loud signal. it has a volume control, coarse pitch knob, and a fine pitch control that is switchable between a potentiometer and a light-dependent resistor. a quarter inch output jack and on/off switch are on the side of the die-cast aluminum box. the unit is powered by a 9v battery (not included…sorry).

demo video:
(sound was also recorded by the digital camera, so it is extremely compressed…volume control doesn’t seem to do much in the video and much of the bass was cut)
