Help with Leyden Jar Answered

I have seen many of the instructables about building a leyden jar, but I built two and I cannot seem to make either of them work. First I made the glass one. I filled it with salt water and stuck a long nail in through the lid because I couldn't fit my hand in to wrap it with aluminum foil on the inside. I sealed it well with hot glue and taped a very neat, crinkle-less strip of aluminum tape around it, the kind that is used for repairing air ducts. I tried charging it by rubbing around a fuzzy blanket on the carpet. That always produces a big spark, so while my brothers were rubbing their hair on the blanket and carpet, I was holding the metal tape around the glass jar with one hand and touching the grounded screw on the electrical plate with the other hand. When my brothers touched the nail on the top, we both felt a shock but when I tried to discharge it by touching my fingers to the nail and the tape at the same time, nothing happened. I don't think it is holding a charge at all. Next I didn't touch the metal tape at all, and we rubbed our hair on the blanket and touched the nail. But when I tried to discharge it, the same thing: no spark. So I assumed the glass was too thick, so I made the plastic one. This is made out of a Tang powdered drink mix container, I cleaned it, filled it with salt water, and wrapped the inside and outside with aluminum foil, as tightly on the sides as I could. I used a smaller nail this time, but I attached it to the inside aluminum foil with a thin strip of foil. I sealed the nail up and made sure there were no leaks. I performed all of the same tests as last time, but still no results. Can someone please help me figure out where i am going wrong? Thanks :)

How to charge a 2 liter pop bottle leyden jar with a DC power supply?

Okay. So I am having some difficulty with somthing that should be simple. Leyden jars. I know that you can charge them using static electricity, but I need to know exactly how many volts are being pumped into this thing for a physics project. Because of this necessary knowledge I require, I have been trying to charge it by connecting pos and neg to it but that does nothing..... Any help how I would be able to do this would be great. Thanks

What should I expect to see from my Leydens jar? Answered

My son has built 3 different Leyden's jars for a science fair. None seem to spark. The foil is very smooth( it looks like it was painted on) There are no holes. I've tried different chains. I've tried glass jars, as well as plastic. We are trying to charge to jar by rubbing a balloon on our heads and touching the metal ball on top. We hear a "pop" but never see a spark. We've continued this up to 100 times, and still no spark from the wire which touches the outside foil, and points to the metal ball on the lid. I'm definately no scientist! Do you have any ideas? I've tried holding the jar while charging it, as well as sitting it down, and I still get no results. The closest thing I've gotten was the balloon appeared to act like a magnet; it pulled the plastic jar closer when the balloon had static on it. Thank You, Jodie

Can I Use an LED chaser circuit to make a large, sequenced coilgun? Answered

I saw an easy adjustable speed ten LED chaser circuit on the web and was wondering if I could use it to control relays in a coilgun that would be sequenced and therefore acheive higher velocities than others? Also, could I use a Wimshurst machine and homemade capacitors or leyden jars to power it, or do I have to use a ton of camera capacitors? Thanks!

What is wrong with my VDG?

I have just finished my small van de graaf generator but have run into a problem. I am only really building this small one as a model for my future large VDG so it is not to important, I would just like to find out more. My setup consists of two wooden dowl rollers built up with tape to "bevel" them. the bottom roller is coated with paper while the top is coated with teflon tape. the belt is a section of rubber balloon. the tube is a PVC pipe which is split so i can easly open it up and make ajustments. i have found this setup to be very good and can often achieve 2 CM sparks whith only a beer can as a top load. The problem is after about 5 miniunts the output will slowly decline untill I can no loger get any sparks. when this happens i have to open up the PVC coulom and clean the belt and rollers with an alcohol wipe. After wards, the machine continues creating 2 CM sparks until i have to clean it off again. I do understand the fact that dirt will be attracted to it and that enough dirt can bleed the voltage away but i do not think this is the case as i clean it so often and it is all sealed up. I just wanted your feed back because it is becoming tedius and i am starting to wonder weather it will affect the larger van de graaf. Thanks In Advance

Is there any way to change the capacitance on a leyden jar/ bottle capacitor? Answered

I am trying to build a capacitor bank for my tesla coil. I am running two 15 kv transformers in parallel for 120 mah. I was running a bank of 7 .015 mf capacitors with 4 wired in series on each one but they burn out incredibly fast. I need a way to build my own that will either withstand the heavy stress or are simple to replace. Either way they need to be the exact capacitance of my tesla coil.

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 do I charge my Capacitor? It's a 82 volt.

I have an 82 volt, 8200 uF capacitor that I got from an amplifier years back, To this day, I just shorted it out to release the spark. Now, I want to use it in a Coil Gun/Rail Gun. I am using just this one capacitor, but I heard you can make a coil gun from a camera flash capacitor as well as it's charging circuit.. I tried to charge the cap in parallel and series, parallel worked, but only produced a very short spark and not enough energy to shoot anything in the coil gun whatsoever. Can I wire my capacitor up to the camera flash circuit in place of the short capacitor that originally came with the camera? Or do I need a more sophisticated charging system...? Also, if you guys don't mind, Would you explain to me how capacitor capacity works, as well as charging them? I am fairly new to capacitors and quickly discharging, however, I can just use a simple leyden jar to shoot my coil gun...... right?.. I do not know anything about resisters either, and what they do for capacitors. I know that I hooked one up and glowed red hot on my capacitor.... yeh heh heh.... --Thanks in advance.

Tesla Coil Capacitor help

I have just started building my first tesla coil. I am fairly experienced with electrical stuff and high voltage but I can't seem to get past building a homemade capacitor that will work. My first attempt I built eight Leyden jars in parallel that were constructed from glass canning jars and metal tape. Next I tried lining a 5-gallon bucket inside out with aluminum foil. Lastly I tried assembled a rolled capacitor with aluminum foil as the plates and wax paper as the dielectric (about 10 square feet). All of these have failed in a similar fashion; I hook them into the circuit and the spark gap wont fire. There is no arcing however the bucket and jar constructions made a faint noise similar to a capacitor charging. I have seen instructables and videos with only three or four Leyden jars in parallel and the spark gap is firing. I don't know whether the homemade ones just don’t have enough capacitance or if it is something else. If anybody has any input on the problem please help. P.S. I am using a 14kv 35ma 60hz oil burner ignition to power the coil below is a diagram of the circuit configuration

I need to make some capacitor?

I need a bunch of high power capacitors and I don't have the money to buy them.  I have a couple ways I have seen and I have done one that kind of works. 2 L bottle - I don't drink enough pop to make enough of these ?pvc? - could I substitute a thin pvc pipe for the 2 litter bottle Leyden jar capacitors - I saw these cool ones that have a tube like pringles uses, al tape around the outside, and then they just push the can into it as the storage. ?pvc? - Could I also substitute pvc for this. Styrofoam cups - I have read about, but not seen this one.  Could I just wrap a cup in foil and then stack it.  Apply positive to top cup and negative to bottom

Help with building a tesla coil? Answered

I want to build a tesla coil, but I want to verify with the instructables community that it won't blow up, burn down my house, turn into skynet, etc. Here's my plaaaauuuuuuhn: For the transformer, I'll be using an old negative ion generator thing that takes in 120VAC and outputs 7.5kv(pic). For the primary, I'll use old speaker wire in  a cone shape (possibly using acrylic). For the secondary, I'll use 32- gauge magnet wire (pic). And for the spark gap, I'll use two bolts in a box, possibly with a computer fan cooling it. And for the capacitors, I'll just use an array of Leyden jars. My questions: 1. What diameter should the coil form be? I have some random white tubing which has an OD of 1/2 inches, 1/2 PVC piping (which actually has an OD of 7/8 inches), and 3/4 inch PVC piping. And is there a better alternative to these? 2. Should I use chokes on the input/output of my transformer? For those, I think I'll just wrap a bunch of wire around a pen. 3. Should I varnish it? 4. How powerful will the EM be from this thing? Exploding computers aren't that good. If I have made any errrors, please tell me.

Instructables in the New York Times - In a Highly Complex World, Innovation From the Top Down

Instructables, and my Purple Shoes got a nice mention in the New York Times here.In a Highly Complex World, Innovation From the Top Downby G. PASCAL ZACHARYUSER-GENERATED content - from Wikipedia to YouTube to open-source software - is generating waves of excitement. But the opening of innovation to wider numbers of people obscures another trend: many of the most popular new products, like the iPod, are dominated by a top-down, elite innovation model that doesn't allow for customization."New technologies are becoming so complex that many are beyond the possibility of democracy playing a role in their development," said Thomas P. Hughes, a science and technology professor at the University of Pennsylvania.Consider: Electronic implants into human bodies; gene-splicing as common as cosmetic surgery; computer networks mining vast databases to discern consumer preferences. All of these innovations are the result of corporate or government initiatives overseen by elites."The process of innovation leaves out a huge proportion of the population," said Daniel Sarewitz, director of the Consortium for Science, Policy and Outcomes at Arizona State University.To be sure, experts like Eric von Hippel, a management professor at the Massachusetts Institute of Technology, argue that the proliferation of "user-generated" designs signals the "democratizing" of innovation. Armed with inexpensive digital tools and networks, ordinary people, he says, can band together to push their own innovations. They also can hijack existing technologies, taking them in directions only dimly envisioned by the original creators.One example is an electronic community called Instructables whose participants share methods for customizing standard products in unpredictable ways. The chief of Instructables, Eric J. Wilhelm, who earned his doctorate at M.I.T., where he was inspired by Mr. von Hippel, has posted a clever means of turning a white Asics Gel-Foundation 7 running shoe into a purple model. (The $90 official version comes only in a white-black-and-blue combination.)Today's Web-savvy consumers "expect innovations to meet their needs," Mr. Wilhelm says. "If innovation isn't tailored to them, they expect to be able to tailor it to themselves. That is a big change."But does this really mean that elites no longer sit at the top of the innovation food chain?"Elites have a lot of leverage but less than they used to," says Peter Leyden, director of the New Politics Institute in San Francisco. "More people are getting their voices heard." Mr. Leyden sees an emergent American "republic of innovation," where growing numbers of people influence what innovations are made and when.Skeptics, however, say that the rosy scenario is exaggerated and that user-generated innovation is merely a kind of "democracy lite," emphasizing high-end consumer products and services rather than innovations that broadly benefit society."Difficult questions are going unasked about who is participating in innovation and on what terms," says James Wilsdon, director of the innovation program at Demos, a think tank in London.In that scenario, needed innovations can be overlooked. For example, huge amounts of money are spent on improving Web search engines or MP3 players, while scant attention is given to alternative energy sources. Battling diseases like AIDS or Alzheimer's - efforts that lobbying groups in wealthy countries help highlight - attract legions of well-financed innovators, while big global killers, like childhood diarrhea and sleeping sickness, are ignored.Popular pressure to pursue certain innovations sometimes gets results, of course. In 2004, voters in California passed a law lavishly funding a stem-cell research institute - in a rebuke to the Bush administration, which has banned federal funding for such research. "This was a great example of a democratic adjudication of an innovation issue," Mr. Sarewitz of Arizona State said. Even so, bureaucratic and legal delays have meant a slow start for the San Francisco lab, which has not yet received approval to spend any of the $3 billion in promised taxpayer funds.The California example suggests that the balance between expert leadership and mass influence is hard to achieve. The underlying complexity of many innovations demands an ever-rising technological literacy from the public, and yet such an outcome "is a dream that will not likely come to pass," insists Mr. Hughes, a visiting professor at M.I.T.For all the hoopla over the power and promise of user-generated content, consumer-directed design and other hallmarks of our new golden era of democratized innovation, one of the iconic products of our times - the iPod - can't be customized (no, I'm not counting putting on different-colored protective jackets). There is an unbroken line between Henry Ford (with his Model T) and Steve Jobs. The new iPhone similarly reflects the elite, corporate innovator's drive to find one size that fits many.The cliche that committees can't create great ideas, or art, still seems to be true - though whether or not that is the best way to innovate remains an open question. Who knows how much longer?
