Circuit Bent "Animal Caller" with GetLofi.com 555 Oscillator Kit Creme DeMentia
YouTube via CremeDeMentia
"A GetLofi.com 555 Oscillator Kit, available from www.GetLoFi.com/shop, has been installed in this device. The 555 Outputs both a square wave and a ramp wave at the same rate. The square wave, when oscillating at a high rate, fools the toy into thinking that someone is blowing into the toy, which is what would normally control the looping. The ramp wave can be injected into the pitch circuit in place of +4.5v, controlling the warble effect. The pitch resistor has been replaced with a potentiometer and body contacts. Finally a distortion knob was added, which is a 1k pot between the two leads of the added 1/4" audio output."
