Simple Hypnosis And Electrotherapy Dual-purpose Instrument: Traditiona
In short: Traditional Chinese Practical Simple hypnosis. This entry documents a circuit & prototype taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 1420 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Simple hypnosis and electrotherapy dual-purpose deviceFigure 80 is a schematic circuit diagram of a dual-purpose instrument for hypnosis and electrotherapy. Its main part is an inductive feedback intermittent oscillator, which is boosted by the secondary L3 of the transformer T and outputs a 60V double-peak pulse for electrotherapy on human acupoints. At the same time, the piezoelectric ceramic piece is driven to emit a sound similar to raindrops, which is used for hypnosis. Adjusting the potentiometer RP1 can change the oscillation frequency of the oscillation circuit. Generally, during electrotherapy, the frequency is between 120 and 200 times per minute; during hypnosis, the frequency is about 50 times per minute, which is more effective. Adjusting the potentiometer RP1 can change the amplitude of the output pulse and the sound volume of the piezoelectric sheet.The pulse transformer uses an E-type ferrite transformer core with a cross-section of 6×8mm. The E-type silicon steel core of a transistor radio can also be used instead, but the effect is not as good as the former. L1 is wound with 80 t …
