Three loosely coupled multivibrators
Panel · 20.3 × 128.5 mm
Description
After a Dick Smith burp generator: three transistor multivibrators at different frequencies, loosely coupled by low-value resistors so they pull at each other, for unpredictable bursts that rarely repeat. A knob sets each one's frequency; IN turns the sound on and off, and gates or envelopes there give a gradual onset and tail. Audio there makes it a waveshaper. Its LED shines through the panel.
Key features
