DiY PEMF setup - custom pulse repetition rate by SSR triggering the gate of SCR by custom SoX script
a SoX script creates a unique adjustable, variable, pulse rate timing for an experimental DiY PEMF device
SETUP:
SoX script triggers a PULSE GENERATOR, that triggers a REAGATE SIDECHAIN GATE to release sine wave blocks of 58Khz at about 200μS pulse widths each that goes out of sound card to input of CLass D audio amp, output of AMP goes to input of full wave diode bridge that rectifies the 58Khz SIGNAL AC BLOCKS into ~steady enough, DC, which drives the LED input of a solid state relay, that releases a 5 volt power supply's DC current through an appropriate resistor to the GATE of an SCR that releases 5 joules of stored CAP energy into the PEMF treatment COIL
NOTE: 58Khz was chosen by testing and observing the voltage of rectification produced by the diode bridge on a VOM...58Khz produced the most voltage output from the diode full bridge rectifier
The output of the SoX script goes to an LV2 plugin called DIODE PROCESSOR, that rectifies the AC sine waves from the SoX output into only Positive portions of that sine wave ...then it goes to a
chatGPT pulse generator script - (pdmcw3.c)

that takes those peaks of the positive slow sine wave pulses of the SoX signal and converts it into single pulses of square waves output... each being about 200μS each
NOTE: the SoX script includes ANGLE BRACKETs that uT does not allow in their video descriptions, so the script is shown clearly on this video in terminal and a text box
NOTE:
audio you hear on this video is from a VLF sdr receiver picking up the PEMF coil's output signal
NOTE: attempts were made to try and test using CLASS B, SCR forced COMMUTATION, but all tests were negative in working to do that... adding the additional HIGH Q air dux coil with ferrite rods core, with adjustable TAP, to find the least amount of additional inductance needed to add enough back EMF reverse current inductive kick-BACK to stop the SCR from conducting etc... proved to be much easier to get the SCR to STOP conducting, and even though the addition of this inductance from the air/coil/ferrite rods, was added, it did not make a significant impact on the amount of GAUSS OUTPUT from the PEMF treatment COIL wrap of about 20 to 30 turns of twin 16 gauge high volt insulated speaker wire
