I would like to build a "force lightning" glove. Purely for show, no arcing over great distances, not looking to "throw" the lightning, just have it crackle around the hand and between the fingers. Any suggestions where to start would be greatly appreciated.

OK I got one for you all! What I would like to achieve is a realistic lightning effect for Halloween displays. I've tried some different ideas, but none can give me a realistic effect. Most produce a timed effect (2 sec on, 2 secs off, 2 on, 2 off etc...) What I think I would need would be a circuit board or something like that, that would produce a random current to a strobe light source (ie. 1 sec on, 3 secs off, 2 on, 6 off, 1 on 5 off etc...) Could this be done? I've searched all over the internet and haven't been able to come up with anything. Thanks! Wes

Hey Guys, I have wondered on this from a long time. Can lightning energy be stored? Lightning occurs when water droplets rub together right? Which means this is static electricity. As lightning strike the highest point why dont they make a huge conductive bar? And as i know from the various lyden jar projects storing static isnt that difficult. So why dont they do it? I asked my dad that how much is it per lightning strike he said millions of kilovolts if that is true then why dont they store it? My dad said that its because they cant store that much electricity. Is that the only reason? BTW I'm 12 so please ignore my dumb electric knowledge :).

I was sitting here in the middle of a thunder storm and I had a thought, usually the clouds are negatively charged during a lightning strike, so, if you used a large cannon to blast a positive iron ball into the air, you may be able to get lightning to strike it, then collect it to see what the lightning did. So, you would you charge a cannon ball?

I bought a book from Home Depot to learn about household wiring: http://www.amazon.com/Wiring-Complete-Editors-Creative-Homeowner/dp/1580111602/ref=sr_1_1?ie=UTF8&s=books&qid=1279657048&sr=1-1 On pg. 238, about lightning protection systems, it says, "...these instructions are for copper only-do not use copper with aluminum." Why shouldn't we use copper components with aluminum? It's essentially just a couple of lightning rods and a cable leading to a ground rod. I can scan the page if you'd like to read it. They made it sound fairly important.

I've heard of computers fried in electrical storms, even with a surge protector. 1) Is there a better way to protect it, short of unplugging? a friend mentioned connecting it thru a bus, and letting the bus act as a fuse. I'm not sure what he was really getting at. 2) What are the odds? 3) experiences + anecdotes?

I remember when I was a child we learned how to calculate the distance where a lightning has struck by counting the seconds between the time we saw the flash until we heard the thunder. I forgot the number that we multiplied the time by ( I think is the speed of sound). I thought about this after we had a nasty thunderstorm. Does anyone know?
Asked by blkhawk 8 years ago
I'm looking for DIY ideas for creating some lightning on stage at a small venue. The venue is called "The Laboratory" so you can see where the inspiration for the idea comes from. It needs to be impressive and easily visible but self-contained and safe enough to be operated by a run of the mill stage hand. Any suggestions are welcomed, but i was thinking along the lines of a large van de graff in a spark cage of some sort or something along those lines. I also have to take things like size, cost, maintenance, and complexity into account. I am not an amateur but I have never attempted any true high voltage projects. Any questions or suggestions are welcome. Thanks for the help!

A friend of mine is offering me big bucks if i build him a pair of lightning gloves which would shoot large sparks or lightning from one glove to the other. now because ive never built a voltage multiplier befor ei would like to know if theres any problems with my idea which is i get a small 12v battery pack for racing car i connect that bttery (with a resistor ) to a transformer i then make a voltage multiplier with hv capasitors and diodes to multiply the voltage until a certain voltage is obtained. however i do not know how hoigh the voltage should be so that it is not lethal, but can jump at least one meter from one glove to the other. also as a safety precaution a large copper wire suit should be worn which me and my friend used on my uncles high voltage vandegraf generator whish shot 20m lighnting at us in our loighting suits ontop of our diving suits , and we never felt a thing. anyways, can you please tell e the specs of everything i will need to acomplish my mission?

I'm thinkin of puttin up a high antenna. Due to my location with a mountain between me and broadcast towers, reception can be sketchy. One concern is that of lightning strikes. But if the antenna is grounded, wont that also ground out the microvoltage radio signals? How do I get microvolt signal without risk of megavolts burning the house down? I've done a wee little bit of google research, but haven't seen this question addressed.

Hi iv been wondering... what happens if you put a taser attached to a metal rod and is constantly charging? would it turn into a lightning blade/sword/rod that when you wack/slash someone, they get the pain from the hit and the shock? anyone know if its possible to make one of these?

Hello, this is a theoretical question, as i have neither the time nor the money to do it. Assuming that your electromagnet would not melt with the power of the lightning and is made of suitable electromagnet material (copper wire and soft iron?). What would happen if somebody connected a large electromagnet to a lightning rod and to the ground? I do not know much about this field of physics, so please explain your answers! thanks in advance, jonathan

It's just a curiosity. Anyway, so there I was, reading up on railguns (just for the heck of it), and after reading the part mentioning "millions of amps", it got me thinking, "What power source can provide millions of amps?" Then and there, I thought, "Lightning!", but how I could I use it? Wait... Oh, cranes! I could stick the railgun on a crane, then whenever the crane gets hit by lightning, it would fire a projectile! Now, who's willing to risk their lives to load a piece of metal up there? :D Nah, just joking. Anyway, I was just wondering if this idea would be feasible in the first place, and what would it take to implement.

I've looked throughout the internet, but I still haven't been able to figure out this one When air conducts electricity, say when lightning strikes, the electrical field breaks down air molecules... So, it breaks the intramolecular bonds between gas atoms in nitrogen molecules, oxygen molecules, etc. The atoms are then ionised. But then somewhere, I got the information that ionised air contains BOTH positive AND negative ions. How is this possible if the gases are non-metal elements and only form negative ions?? When an electrical current does flow, what carries the charge? The negative air ions? or electrons? I've found sites that say one, and sites that say another. Thanks in advance

Not sure if this should be posted here, Outdoors or Square Pegs, but it's art related so I'll ask here. I once saw a how-to video, I am 90% sure is was on this site. but there is a chance it wasn't. I would like help finding it again. From what I remember, the person showing off had: a car battery, a long needle, plank of wood and some chemical. the process I remember was (but may not be 100% accurate): 1. (s)he painted on a layer of chemical (or acids) on the wood 2. stabbed the needle on the wood 3. connected the battery to the needle 4. turned the battery on. it then made some elegant, fancy patterns, like a bare tree, or a lightning bolt. lots of 'branches' and paths were burned into the wood (without manual intervention. it was 'natral'). like a chemical reaction. if anyone has the name of this technique, or a video/instructable/guide, I would really appreciate a link. Thank! EDIT: solution found: it's called "Fractal Woodburning" (go on youtube for some videos). I should have known, I love fractials! you need: saline wood needles and a high-voltage power source. and patience.

I had an idea today I thought would be interesting after reading about this - http://www.richardbox.com/ - how about integrating a fluorescent tube into the handle of an umbrella. If the tube was supported inside an acrylic clear (or coloured) tube and had some kind of connection to the handle and to the tip of the umbrella, then when walking under pylons, in a storm (eek?!), or in any situation where there would be a big potential difference between something above the user and earth. This could be interesting near tram/train lines.What do people think?

So far I was lucky and never got a lightning strike or other power failure to induce high voltages into my house and equippment. But over the time I got several requests from friends to take a look at things after literally all connected electronics in their house got fried. In some cases there is only a total write off as due to a lack of surge protectors inside all unwanted juice made it's way into vital components. Like a brand new Samsung TV where the replacement of the power board was the only option - which makes you wonder... But in other cases, like microwaves, induction cooktops, computers and such I had some good success with the repairs. Guess it comes down to purs luck on both sides, power surge was not too bad and simple components on the input side failed quickly enough to prevent damage to microprocessors or other sensitive parts. Right now I have an induction cooktop here again that failed after a mains transformer in street blew up during a thunderstorm. I can tell it was bad as everything in the area of fried parts has a vaporizsed metal film on the surface and not much is left that was a surge protection. I cleaned all up, replaced the varistors and missing parts of the traces on the circuit board but the cooktop is not performing the way it should anymore :( At some stage during cooking it turns off with a meaningless error code stating the input voltage was out of bounds. So my next attempt was to literally remove every single component from the filter and power supply board to measure for any possible connections between the traces. By doing so I noticed several points where I had a quite high but measurable resistance in areas where there should be none. Mostly on the direct input side where the varistors tried to save things. So I used my Dremel in a tin drill press to cut the circuit board aourd the affect areas (where possible with a drill, otherwise with a thin grinding disk).. Sure enough I was greeted by charcoal colored dust in several areas. After removing all material until the dust was "clean" tried again and this time all seems to work fine. I would like to use this topic to offer some help and guidance in case you have devices that suffered a severe power surge of some sort. Many of us either have no insurance to replace those items or even if you do the device might be expensive enough to try a repair despite getting it replaced. Trust me, even it went up in smoke there is still a chance to fix it in some cases and if proper protective circuits were in place the repair could as cheap as a few Dollars for replacement parts. To get useful advice the following things should be included in your request: Some clear pictures showing a close up of the affected parts - if there is visibale damage to be seen. A brief description of what happened, e.g.: lightning strike directly into the house or outside power lines, generator or inverter failure or simply that the power company stuffed up and your entire street was affected. Of course you will need the means to take the device apart for investigation and also some basic soldering skills or somehow how has and can assist you. But if you are up to the challange I am willing to help if possible.

Seriously, I had this idea the other night when it was really stormy and lighting out like crazy. Why can't they make large collection centers for lightning, kinda like a leyden jar in principle, with a humongous lightning rod to attract lightning? Lightning is absolutely free, if it was harnessed to power our cities, at least some of them, it would be so awesome! No pollution, no cost to produce, other than construction and maintainance of the facility. You could just plug it into the existing power lines, with some massive step-down transformers of course. So why don't they do this, at least experimentally? Lightning is unpredictable, you say. No problemo, you put this collection thingie in an area where there are a lot of storms, and add a lightning rod-a BIG lightning rod. It's very dangerous, you say. So make it completely automated, no humans required, and put it away from residential and business areas. You say lightning is much too powerful. Nonsense, you can make a big enough facility to contain it. You say I've gone off my rocker...you may have a point there... I know it must be dumb, and have a flaw I am not seeing-do any of you science experts know what it is? Why won't this idea work?

I'm planning on building the device specified here: http://www.eham.net/articles/9272 I want to place it about thirty-forty feet above the ground, between two large trees. This would be above the power lines in my area, and also above most everything else besides the trees themselves. This seems to pose a significant risk of having lightning strike it. I don't want to have to put it up and take it down every time there is a storm (nor am I always here when there is one). Is there any way to make this safe from a lightning strike? P.S. I know this works--one of my friends works for Honeywell and, when asked whether or not this was true, he explained that they have had conferences, lectures, etc. about the problem of static buildup on power lines. My line length would be around 200-300 feet long, which is certainly not anywhere near the miles that many HV hydroelectric lines in my area run for, but it is still quite long.

OK I had this idea. I was online and thought up this idea for an anti gravity machine. This is it: use extremely static negatively charged materials for anti gravity. It could work the same way lightning clouds do. The base of the cloud is negatively charged and the ground become positively charged. Now if the material of the anti gravity "thing" is charged with static electricity, wouldn't it repel the ground? Now I am by far no expert in any of this...I just thought it up. What do you guys think?

I recently built a tesla coil, and after some demonstrational use in school the transformer burnt out (it wouldn't do anything, and a red light appeared inside). I have already ordered a new one, but i want to prevent this from happening again. Any tips from experienced tesla coilers? thx in advance, all help is appreciated. additional details: transformer: 6500v, 21 ma. ordered here. the tesla coil has gone without sparking for a few seconds at a time, however resumed after turning it off and back on. could this be related to the spark gap length or something similar?
Asked by biolethal 8 years ago
My high school recently had an engineering fair, and my friend had built a tesla coil. Its has multiple spark gaps, an RF filter (I think thats what its called), a 120 to 20000v transformer, and toroid top-load, if any of that matters. We/I would entertain ourselves by standing away from the coil and holding a fluorescent tube (by the glass with bare hands, not by the contacts) near the top-load and watching it light up. Even though I was well away from the coil, my forearm muscles would twitch, especially it the coil spark hit the contact on the other side of the tube. Then if anybody touched me, both of us would feel a shock and the same slight twitching (the same kind of twitching you feel from those electric muscle stimulators with the pads you put on sore muscles). We even set up a chain of about 5 people holding hands, and all of us would feel a shock, even though only the first person in the line (aka me) was holding the fluorescent tube near the coil, with my hand on glass, no where within range of the streamers coming from the top-load. Now for my question: is this dangerous? (I know its non-lethal, im talking about my nerves) And what exactly was happening? because it was not an incredibly large coil, and i know that the field of a coil is much larger than the actual streamers. I also read somewhere that insulators dont work the same at incredibly high voltages. I think what I was feeling was the skin effect, and the charge came from the excited electrons in the tube. If my ideas are correct, then wouldn't me holding the tube be just the same as if i had just put my hand near the top-load and let the streamers hit me?
