The hypnomelder is full-functioned, and it can do many adjustments, the effect is also good. The square wave generator consists of BG1 and BG2, which can generate the hypnosis signal pulse. By adjusting resistor R2, the pulse width (i.e tune quality) can be controlled; by adjusting resistor R3, the pulse interval can be controlled. The best hypnosis signal can be got by repeated adjustment. By press switch AN, the circuit begins to work, it powers the pulse generator composed of BG1 and BG2, which makes the generator generate hypnosis signals.
