ALSO i'd like to read the value at primary could i use resistors to divide the voltage and then read it from a PIC a/d, does the a/d converter have a thevenin equivalent value??
i am following this guy:
https://www.rmcybernetics.com/projects/DIY_Devices/plasma-gun.htm
and i notice that he is grounding his secondary through his hand, now when i read up on this everyone says not to ground secondary back to the battery, but since his coil is so small its ok to use like this.
Since i have about 220 watts available to me for my hand gun, plus idk yet the size of my secondary, so I am hesitating to run it through me, is there a better solution for ground here?
thankyou i will do my divider with 1k then, i just like to double check on things like this...
what about this:
if i used a second toroid on my secondary, at the same side as the first toroid but wound the second secondary backwards over the first one &maybe some insulation , so to create a inverse flux on the wire, would that work? am i getting warm with this? I googled it and it would be similar to a bipolar coil
I may forgot to mention, one of the reasons im being so safe with the grounding this time, is because im using a LiPo battery, and iv seen what happens when they get an improper charge. HOw do i calc the size of the spike
its just those little handguns making a 1/2" streamer really isnt that worthwhile, i finally figured out that the reason i like these things soo much is that it discharges to air without need for a ground
could i protect that with a HV diode, at vcc and ground?
im noticing where some sparks jump from the HV wire to ground, but then some just "free fly" in the air, i think i am having trouble establishing why the difference occurs or is this just another power thing?
i was hoping i could do a 2 in 1 thing for my gun, so by em toys i mean a can crusher, with around 1/3 to 1Kj discharge, is my idea for now anyway, however i cannot find a seimconductor that goes to 4Kv either, so i may need to use a triggered spark gap, (would it work like a xenon flash trigger? where a 10kv trigger voltage is used, but how much current do i need for that?
sry buy just tellme one more time no lipos! what if i used a choke to protect battery?
btw...what is the limit of safe past 72WATTS?
OY! gone over and over this one 10W CAN KILL! Voltage and power does not kill - CURRENT kills. Voltage is only an enabler!
"The damage caused by electric shock depends on the current flowing through the body -- 1 mA can be felt; 5 mA is painful. Above 15 mA, a person loses muscle control, and 70 mA can be fatal."

by these standards I would estimate that a fresh 9V battery on your might be a couple mA.

It's important to note that 70mA is WAY more than enough to kill you. 30mA is enough to be lethal, if you touch it wrong. Especially if your hands are sweaty, or if you create a path through your heart, it can kill you instantly. You must be extremely cautious when working with this kind of voltage and current.
true but explaining that to the "voltage is king" class of hobbyist that you run across borders on impossible!
I'm not really sure what that has to do with what we were talking about. We were discussing lethal currents, and it cannot be debated that current is what ultimately kills. The voltage only determines how easily the current can flow through the skin.
