The electrostimulator or electronic massager consists of a circuit that produces high voltage pulses that are controlled in frequency by P1 and in intensity by P2. The application is made through electrodes connected in J1 and J2. Pressing S1, the neon lamp lights up to indicate the operation of the device (presence of high voltage). The transistor Q1 must be mounted on a small heat radiator and the transformer T1 has a primary winding of 110 / 220V and secondary with voltages between 5 + 5 and 9 + 9V and currents between 100 mA and 300 mA. The C1 capacitor can have its value changed in the range from 470 nF to 2.2 uF to obtain the frequency range that best adapts to the desired application. The electrodes can be metal plates or metal tubes.
