As long as it was only painful, not dangerous (didn't fibrillate/paralyze you etc). Although, 30mA in, divided by 6*2^(1/2) is only about 3mA so I wouldn't expect much worse from it...

Thanks for the links, I'm at that unfortunate point where I know bits of what works how, but not enough of 'this can be done like this' examples. As for the fly back, I have heard of them (and where to find them) but I haven't ever dealt with one and I have conflicting information in that some...

I feel like I'm missing something here, isn't it that for resistors in series the same current is across each if them and found through V=IΣR therefore, if there are two resistors, and they total to 2,000,000 ohms, that it would limit the current across them both when a 10Kv potential is applied...

Hi, thanks for the reply, the reason I was thinking of using a potentiometer/potential divider circuit was so that I could also drop the output amperage to about 5mA, which would be painful, but not too dangerous (relatively speaking) to be shocked with. Since the value of whatever resistor I...

Not We aren't using a vacuum system on it, the design is based off of one that appeared on geo-cities a short while ago. We have a couple if op-amps set up to control a peizo disk (bending it where it needs to go) and create outputs for an oscilloscope's x and y inputs. We then have the 'z'...

Low voltage I have done some messing around with an arduino for led cubes etc & I have an 'almost' finished a scanning tunneling electron microscope which I have been building on and off fir a while now. Currently nearing completion is a nixie tube clock, but that's at about 300V (powered from...

Hi At the moment I am trying to design a variable HV psu for some projects (some of which haven't even been though up yet, but I want to ability to run everything for hv off of the one psu). The idea is to use a transformer(which would double as an isolation transformer) with a 600:2500 ratio...

At the moment, messing around with high voltages (lasers, tesla coils, lightning globes etc), actually I am in the process of attempting to design a hv psu (at least 30kv output), just had to jump way back to square one because I realized that 1626300 ohms worth of potential divider would...

Hi Obligatory introductory post: Currently a student in year 11 (Australian equivalent of high school junior?), interested in becoming an electrical engineer.

Hi I'm trying to design a circuit to be hooked upto mains ac, and it was recommended that I should use an isolation transformer for safety purposes. 1) what purpose does this server, I know that it allows power to pass without the circuits being joined, but what affect does that have/why is it...
