Hypnotic device circuit with a timing circuit

Figure shows an simple hypnotic device with a electronic timing device. When the electrode of teh circuit is touched with a finger (2~5 seconds), immediately the headphones will have a small sound of "Putt-Putt", which encourages people to sleep. About 20 ~ 45 minutes it can be kept active.(The ON time depends on the contact time of finger with K), So, the power of the hypnotic device will switch OFF itself ,when the contact of the hand is taken. So, there will not be a waste of energy.

In the circuit diagram, the timing and rhythm generator circuit consists of two parts, R2 and C1 which determines the time delay, RP, and C2 control the speed of the beat (usually 3 / 2 times / sec ). Small speakers can also be used, instead of ear plugs depending upon the convenience of people.High-impedance headphones can also be used, simply access VT3 collector circuit can be changed.This can be a solution for people who suffer without sleep or reduced sleep too.
