Lightning lighting

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

Storing Lightning Energy? Answered

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 :).

Why should you build a rooftop lightning protection system with either all copper or aluminum components? Answered

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.

How to positively charge something? Answered

So, you would you charge a cannon ball?

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.

Ionized air principles? Answered

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

(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.

I should have known, I love fractials! you need: saline wood needles and a high-voltage power source. and patience.

Electronic repair after a voltage spike or power surge

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.

Why don't they use gigantic leyden jars to collect electricity from lightning and use it to power homes?

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?

How to make indoor lightning with Led Strip + Battery + Solar Panel?

Hello everyone, First thing first. As you know im new to this =) However, im familiar with wiring & soldering some easy parts. I will try describe my problem detailed as possible for future readers with same problem. My Grandmother living on a top of mountain for like 5 months in a year. As you gues, there is no electric. So, i decided to give her indoor lightning with solar enegry and led strip for at least 2-3h in a day. Place where she lives is mostly sunny. I can say thats about full sunny 3 months of 5 and semi-sunny or cloudy 2 months of 5 in total (There will be no autumn or winter usage). I'm not planning to use 5m of strip at one connection. There are 4 rooms in the house. I'm thinking 9 leds (or 12) in each rooms. Lets say 12 for fixed amount talk. That makes 12 x 4 = 48 leds in total. If light would not enough for her, can consider increase led numbers 24 in each rooms. Also dose not excepting light from leds as normal lightning. Just wanting she would be able to see whats around. My plan was simple before starting seacrh (LOL). 1 or 2 entry level solar panel(s). A backup battery (Li-Ion) charged via solar panel. And leds. So, things were not gone as expected of course. I had searched like 5-6 hours about this in past 3 days. I had read every similar situations (or a part of this) that i find on here or somewhere else (other forums). Situations was different all the time. But, i learned a lot. And this is not enough yet. I have learned there are a few types of 12V strip led (Do not remembering the link, sorry). But those are; 2835, 3014, 3528, 5050 and 5730. If i did not get it wrong, when number goes down brightnes goes down too. But, energy consumption goes down too. There are a few things about led strips to know: There is a Power Consumption number for all leds. But, that is not means all 5050 leds will consume same amount or other numbers. And its important about feeding your led strip. It depends on brand or manufacturer. If i didnt get it wrong (again). If you feed your led more than its required Voltage, it means you are grinding its life cycle. It will gonna die faster than normal life time. That is also causing overheat on leds strips. However, not sure if its life time will be longer than normal if you feed it with less Voltage. Forexample; feed 12V led strip with 11V. Did not see anything about it while searching. And last thing that i have learned about leds while searching is, led strips can be different on led numbers on them. Mostly (that i had read) they are 2 types on number. One is 60 leds on 1 meter and other on is 30 leds on 1 meter. I have learned realy a lot about Li-Ion batteries at this link https://www.e-cigarette-forum.com/forum/blog-entry/9-battery-basics-for-mods-the-ultimate-battery-guide.4848/ I have learned "do not over voltage your leds" and alternative methods in theory at this link http://electronics.stackexchange.com/questions/135611/what-happens-if-i-supply-18v-to-a-12v-lighted-switch I have learned "sometimes exact V is not enough when using solar panel" at this link (still confused about DC Booster part about will i need it or not) https://www.instructables.com/answers/Why-can-I-recharge-lead-acid-batteries-with-solar-/ I have semi-learned "how to calculate Watts, Amps etc" at this link http://diy.stackexchange.com/questions/18225/what-do-i-need-to-install-led-strip-lighting I have learned there is a "Ohm's Law" and calculate/use it at this link http://electronics.stackexchange.com/questions/117594/how-to-get-12v-5amps-battery-setup-for-led-strip I have consolidated my new infos at this link https://sirs-e.com/general/battery-powered-led-strips/ I have learned, that i can improve my batteries capacity or voltage (or both same time) with series/parallel connecting them at this link https://www.batterystuff.com/kb/articles/battery-articles/battery-bank-tutorial.html And few more links via links at above including i have learned there is a battery type 12V named "Lead Acid Battery" and variations of it.

Ofcourse there will be small switchs in each room to lit on/off led strips. 4 x 3.7V Batteries makes a total of 14.8V or 3 x 3.7V batteries with 11.1V will do the job too? Can i connect 3 batteries in series and parallel for improve capacity and voltaj? If possible, prefer to use batteries in day time too. Not for long day time or load. I gues like 5-10 mins in day time for dark rooms. Detailed explanation or step by step guide link would be freaky awsome. I have learned many things while searching but in theory. As you know im all about strange to terms. And there will be few future readers like me too i believe. I'm sorry about my English and long links. Do not know how to shorten them.

Tesla Coil Safety?

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?

So today I got a sneek peek of the Maker Faire at Young Maker's Day. And with it, something that simply blew me away. This tesla coil demo uses two TALL towers with lightning bolts coming out the top. The lightning bolts are what make the music! And the drums are robotic! That's what's waiting for all who are coming over the weekend. Enjoy! I included a video. Young Maker Day: Amazing Tesla Coil Music! @ Yahoo! Video

Numeral 4 cake?

I need to make a numeral 4 cake for my grandsons's birthday. He wants it red (for Lightning McQueen) so I think I will then add road markings and car.

How do I convert a USB Plasma Sphere to battery power?

I'm trying to make a "tesla cane" (just a cane topped off with a working plasma sphere) for my cousin's steampunk-themed wedding. I already have a USB Plasma ball (Model is here: http://www.thinkgeek.com/geektoys/science/964e/?), and I'd like to make it run off battery power. I'm good at soldering and dealing with small wires, but I've never measured voltage or anything like that. Advice? Has anyone attempted a project like this before? It seems like there are tons of "convert batteries to USB" tutorials but not many of the reverse. :)Thanks in advance!

Plasma alarm clock?

I am thinking it might be fun to hack the speaker output on a digital alarm clock to somekind of plasma device that uses a flyback transformer. Something along the lines of a lightning alarm clock that was released a few years back.

Just read Aeshir's b***h-fest, I can top that

Lightning hit my tree, everything that is wireless and powered in my house got knocked out permanently, this includes: flat panel tv, 2 CRT tv, nintendo wii, wiimotes, every cordless phone, every clock radio, and my cheapo routereverything that was unplugged and without batteries in them was fine, also things that are not wireless are fine, there was no surge or anythingI don't know how badly it affected my neighbors and finally, some picshttp://s156.photobucket.com/albums/t31/frank26080115/Lightning%20Strike/?action=view&slideshow;=true
