Simulating the neural brainwave output of an epileptic Robin This synth is capable of communicating with any kind of bird anywhere in the world at any time. a stroboscopic blinky light that plugs into the left jack socket is used to blind the bird and provoke epileptic fits. The bird then emitts stepped tone brainwaves out of the right jack socket. Excellent for confusing and bewildering any kind of surface dwelling land-mammal. One knob for controlling the rate og blinkage (or freq of 2nd osc if jack is plugged into a speaker) and two knobs for controlling the first oscillater witch is a stepped tone generator. The unit runs off a 9V battery wich is easy to replace.
