Matt circuit

This is a small, portable set, designed for those aiming at look improvement. The Bio-Stimulator provides muscles' stimulation and invigoration but, mainly, it could be an aid in removing cellulite. Tape the electrodes to the skin at both ends of the chosen muscle and rotate P1 knob slowly until a light itch sensation is perceived. Each session should last about 30 - 40 minutes.  Portable Muscular Bio-Stimulator Circuit diagram : Portable Muscular Bio-Stimulator Circuit Diagram C1 generates 150µSec. pulses at about 80Hz frequency. Q1 acts as a buffer and Q2 inverts the polarity of the pulses and drives the Transformer. The amplitude of the output pulses is set by P1 and approximately displayed by the brightness of LED D1. D2 protects Q2 against high voltage peaks generated by T1 inductance during switching. Parts : P1-----4K7 Linear Potentiometer R1-----180K   1/4W Resistor R2-----1K8  1/4W Resistor (see Notes) R3-----2K2  1/4W Resistor R4-----100R   ...
