Square wave generator - low cost

To add a contribution for the discussion...

A device named spooky2, with a price between 100 and 200 depending on the model, seems to be interesting. It has lots of capabilities for frequencies generation and can be set using a computer with USB connection. It has an acessory that can "listen" the body frequencies in order to identify the frequency of pathogenics to, then, send a "counter frequency" to kill it. The concept seems to be very good, but I do not know about the practical results.

It is able to deliver frequencies up to 20 volts. I placed a question on its forum because Dr. Beck used 27 volts and Sota Silver Pulser uses 31 volts. It is not clear for me if 20 volts is enough to enter deep of if will stay just over the skin:
