A DIY electromagnetic shock wave device, cost unknown.
1. High voltage charging system
2. Triggered spark gap (http://www.excelitas.com/downloads/…ransformers.pdf).
3. DC power supply.
4. Timing control circuit using 555 integrated circuit.
5. Flashlight with exterior rubber coating to prevent shock hazard.
6. Metal post / nail.
7. 22 gauge magnetic wire.
8. Cylindrical insulator covering metal post / nail.
9. Cylindrical insulator covering magnetic wire after constructing electromagnet.
10. Cylindrical piece of metal for the diaphragm.
Place insulator over nail.
Wrap magnetic wire around nail creating electromagnet, keep it neat and tight only one layer.
Place insulator over electromagnet coil winding.
Place metal diaphragm over insulator.
Remove light bulb from flashlight and install electromagnet device in it’s place.
Everything must be electrically insulated to prevent shock hazard.
Pictures provided for applicator head and timing control circuit.
This is where things get real tricky with science. The focal point of your DIY device needs to be determined for greatest effect. The high voltage level will determine the BARS of pressure. You want to stay between 1 and 5 BARS. Maybe this can go viral as an instruct-able and someone figure out how to calibrate it.
Oh woah, amazing! Thanks! Very different underlying mechanic from the ultrasound, but this is certainly useful either way. I was thinking of a 555 circuit already.
