Marx generator - what do you want me to zap? (Videos!) Answered

http://www.amazing1.com/negative_ion.htm has a 12vdc device that i used to build the same thing u are describing... all you would need is a 9v batt and a switch with a lil wire. i know it says its 12vdc but only put 9 thru it if u are attaching it to yourself because it will create enough voltage to creep up the side of ur boot. if ur smart u will use a momentary switch rather than a toggle as i did to avoid some very uncomfortable situations lol

Camera film - I might use one that is already used...
Near small invertebrates - I will try do that, however the spark might kill them...
Through a grape - Possible, will do that as soon as my parents gets some grapes...
Through a pickle - Not possible, my parents does not buy pickle...
A cloud of flour - Hell, no! It WILL cause an explosion, and burn down my lab!

lol "lab"

Yep. my little wooden garden shed had turned into my laboratory!

all i have is a table outside with a bunch of circuit boards on it

Can you do it in your house?

ya, but my room is usually covered in free samples, wires, bits of solder, and homework

Haha I have a decent workshop my desk is crowded with: my keyboard 2 monitors lamp homemade computer modded psu lamp mouse giant breadboard various tools and components I do all of my soldering in my workshop I do all of my designing and prototyping in my room at my desk oh, except stuff involving ac mains I do that in the workshop cause if I trip the breaker my computer turns off and that's very annoying

Wow! You must be lucky to have a decent workshop! My lab (well really, it is a workshop) is very tiny, all four walls are crammed up with boxes and stuff... :( However, I manage to to some projects!

I'm going to get a new workshop as soon as the building that we have for our shop collapses. My dad told me that he'd give me a workbench and that he'd build a new shop and - very possibly - get a lathe. (I just hope he gets a metal lathe, so that I can lathe metal and wood and wind my Tesla Coil secondaries!)

Wow! you would be very lucky if you do get an lathe! (I wish I had one...)

noice I have a lathe that's about 100 years old, but still good. It can only do wood, though. I wish I had a metal lathe...

Cool!

^{I bet that is what you used to wind your tesla coil...}

lol, when i trip a circuit, half my house dies ) : and my parents are all like, "what the hell was that?" most my electric-working stuff is in a cardboard box, the rest of it is on the floor/on my table : )

I had that sort of problem before, and a little 2 amp fuse saved me from being banned from my workshop. I was testing some transformers using the mains power from the converter, without realizing the bad transformer would short out the mains, I heard loud buzzing noise from the converter, and my shed blacked out... Later found out the fuse had blown and my dad's converter is alright, (that was close, my dad would band me from my shed if the converter was blown....)

I use to freak out when the breaker trips, I would be like "OMG, what if I burned out the wiring in the wall, what if I broke part of the house! OMG I'm not seeing any of the breakers tripped! Oh, wait a minute, tripped breakers only look slightly different than non trippen ones, sigh...."

if any of those bad things happened, i would just call management, (i live in appts) and they would fix it, i'd blame it all on the faulty wiring(30yr+ old)

how bout a cluod o' olive oil spray?(tries) nvm....also, try with some jell-o and vienna sausages(honestly, i love 'em)

A small cloud won't burn down your lab, just blow a handful across the spark-gap...

Kiteman, you pyro!

Okay... I will do it...

lol, cloud of flour, it's not going to do that Kiteman! you know what i'm talking about! he would need to get the precise amount of flour particles in the air, not impossible, but highly unlikely!

Okay, the spark does hit the ice, however instead of going through the ice, the spark travels along the surface of the ice and to the metal foil. If the ice wasn't there, the spark cannot jump...

Ah.

try hooking it up to a twelve volt battery (dont use your fingers to hold the LED ) you will end up with a loud bang and plastic every were.

Done. (Except the styrofoam and IC part)

woot, the led glows does the led still work normally?

Umm, I don't know, I had not tested it yet... But I will test it soon.

a microwave transformer could work, but mind you MICROWAVE TRANSFORMERS ARE VERY DANGEROUS. They have high voltage AND high current output Also Neon Sign Transformers are pretty dangerous, especially if it can output more than 15mA. it takes 20mA to kill you, and with the high voltage potential it'll be easily reached.

What kind of outputs are we talking here? I never really saw figures on anything...

MOT's outputs are usually 2kv (2000 volts) at a couple hundred milliamps (I think it's around 200mA)

Most microwave transformers give out about 500mA, some may even give out 2 amps!!!

Hmm, 50KV at ~8ma is a distinct possibility...

Done...
