But it's embarrassing when I get over 75-80% power as it causes a muscle spasm similar to that which afflicted Dr Stragelove

content: Could he have possibly modified the appliances with some low voltage sense circuit using a Mosfet or JFET or other transistor, that when activated allows the device to get full current? Then he wouldn't need an observer to be "synchronizing" the device turning on and off. You could pass a few volts harmlessly at a few milliamps through your skin, just enough to activate the transistor gate?To bust this thing wide open, we need someone to just modify a light-bulb or drill the exact same way and show how it works. History channel missed a basic electronics lesson opportunity.[EDIT: We have no idea how the devices he is "turning on/off" are actually wired in with the wires he is holding in his hand. We are made to presume it is in series connection to the mains but who knows how he rigged up his devices internally.... They never crack one open to see... I bet there is a power transistor in there and he is saturating the gate to let it go wide open with a small control voltage passing through his skin].[EDIT 2: The history guy almost said it correctly.. he says "Electric Drill".... But if you pause it just right and hit play, he says "Trick Drill".... because that's what it is.]

content: The History channel isn't very credible these days.I saw the guy mention them in that video.I'm being drawn away from mainstream TV just like I am for Windows and mainstream news media.

In fact, 20mA can kill you. In any case, I suspect he did use something similar to what you stated. Maybe a solid state relay was used. By judging from the technical knowledge of the reporter, it would not surprise me if the trigger mechanism was easily concealed or disguised.

content: Quote from: VK3DRB on May 18, 2016, 12:25:50 pmYou can safely pass several 100mA through your body if you do it right:If the frequency is high enough the current will not cause any damage (if the current density is low enough not to cause thermal damage). I have tried it myself by holding a 40W 230V lightbulb connected to a 50W 1MHz source in one hand and the ground return in the other hand. The lamp lit up brightly, but except from some heat I did not feel anything.This has nothing to do with skin effect. Compared to the more wet and salty parts of the body, skin is bad conductor, even at high frequencies. The nerves simply can't react to the high frequencies and because of the quickly alternating current there is practically no electrolysis.Doing the same at DC or 50/60Hz would come to a bad end.

content: +1, TENS units go up to 100mA per channel and its fine, killing person involves more than current...
