Miniature Jacob's Ladder

Hi All, I'm already thinking ahead to next year's Halloween and have an idea about a miniature Jacob's Ladder mounted on top of a pumpkin.  Perhaps taking an inoperative vacuum tube, removing the 'guts' and using the remaining glass from the tube as a protective housing over  the actual Jacob's Ladder. Has anyone ever attempted a Jacob's Ladder on a miniature scale?  Wondering if it's even doable.  Open to suggestions. Thanks Folks! Cheers, Ian

Giant Jacob's Ladder Project

Many, a many moon, ago I found an old Popular Science Magazine that detailed how to make one --it was an old issue! Any ways, about 13 years ago when the builder's for our neighborhood left, I took the flag poles from the front office with the intent of making an enormous Jacob's Ladder. Well, cleaning out some brush I found them again and want to make it again. I am sure the transformer will have to be huge but I am willing to go forth on this project. Does anyone here have any experience on making a giant one?

Will a transformer that outputs 6000 volts work for a Jacob's Ladder? Answered

I've been looking on ebay to find a transformer to use for a Jacob's ladder, and there seem to be a lot that output 6000 volts, and they are at a price that I am willing to pay. So, will 6000 volts be enough to use in a Jacob's ladder? If anyone could answer this, that would be swell. Thanks.

It looks fascinating, and I would love to buy a kit, but apparently they only sell the finished version. I wounder if anyone here has the know how to reverse engineer such a thing, or perhaps knows how to make one already. Really, $169 for the completed thing seems reasonable to me.  I have nothing against buying one exactly, I just want to build it.

Using a desktop power supply to power a flyback transformer for a Jacob's ladder Answered

The title says it all. Is doing such a thing possible? The power supply would act as a 'barrier' of sorts between the wall power and the power of the circuit. The flyback transformer from an old tv would increase the voltage after it has been decreased by the computer power supply for the actual Jacob's Ladder.

Why wont my arc rise on my jacobs ladder?!?!?

Ive been fiddling around with high voltage for a while now and ive been working on a jacobs ladder. The unit consists on a 600v .75a digital ballast, and a flyback transformer. I got it to climb but the arc was very weak. So i did some reading and made a saltwater capacitor for it. I hooked it up for the HV + - out then to the wires. Now i have CRAZY loud arcs but it wont rise, it just sits their and is really bright. Am i just not getting the gap right or what? Any ideas would be awesome! Getting a little frustrated....

Cockcroft–Walton High Voltage Power Supply

Greetings! I have wanted to begin experimenting with high voltages recently and have already collected a series of projects that I would like to conduct. The only issue is that of my high voltage power supply. I have not the funds or resources to buy into a NST or MOT system and ended up looking for alternatives. I at first tried the ignition coil route that ended in failure and have now moved on. My question is, will a Cockcroft–Walton generator be able to run say, a tesla coil, jacob's ladder, or even a farnsworth fusor given that the necessary voltage is outputted from the multiplier.  Kind of between a rock and a hard place here, Thanks anyway!

Looking to brainstorm about a Jacob's Ladder-style prop weapon - Grendel's Fork Answered

I have a friend who is a big fan of Matt Wagner's Grendel comics, and I thought it would be fun to make him a prop version of Grendel's signature "fork" weapon. I can handle the construction of the staff and the blades, but I'd like to get some thoughts about the special effect - a Jacob's Ladder-style electrical arc between the blades. Obviously, I'll need to modify the pictured design a bit so that the blades are electrically isolated from each other - no "tuning fork" configuration. My first thought was to just get a commercial "stun gun" and attach one contact to each blade, but I'm hoping the 'ibles community can help me come up with a better idea. Desired Specs: Hollow, black anodized metal staff. 6' length, 7/8" ID. Separates in the middle via a screw-threaded coupler. Has a threaded socket in one end and a black plastic plug in the other end. (It's an extra upright from a utility shelf unit) Blades - not purchased yet, most likely 440 stainless tanto blades (dulled)  7" to 10" plus a 3" - 4" tang. Unit must be self-contained - no power cord visible i.e. to an external battery pack or wall wart. A removable recharging cable would be OK. Arcing must be triggerable via a switch on the staff. I don't need to actually shock anyone, I just want a flashy visual effect. Simulated arcing would be perfectly fine as long as it looks good. Needs to be sturdy and fairly impact-resistant. It won't really be used as a weapon, but it will undoubtedly get played with a lot. Anybody have any suggestions?

Dismantled a CRT - Usable flyback transformer ? Answered

I've been reading up on Jacob ladders and tesla coils for a while now, and decided to try to make a Jacob ladder (the tesla coil just looks scary and advanced) I've taken a part an old CRT. And I was wondering if you could tell me if it looks usable.  I'm wondering slightly if I broke it when I removed it from the 'plate' it was stuck in. Pictures will show what I mean. Sorry about the bad focus on the pictures. Taken with a phone, and it was slightly too dark for it to be able to take good pictures. The brown cables looks like it's just fast in the flyback transformer, but I did not remove it. I tried to get a good picture of the text that was on in case it means anything to anyone.  Also, what I can gather by looking at this is that the red cable is the high voltage cable, and the low(er) voltage cable is either the grey, or white one. - Is that correct? Thank you very much for your attention, and thanks for any replies. And this site is amazing. I'm just amazed at how creative people are.  Oh, and please let me know if I posted this in the wrong category Zaek.

Rail Gun, full auto?

Unless i am mistaken, rail guns use high voltage rails, and conduct through the rails and a projectile... not unlike jacobs ladders. if we took a jacobs ladder and made the rails parallel, they could be used as a rail gun. right? if so... what's to stop us from having a gravity feed rail gun, something that rols a ball bearing or some such metallic ball or rod onto the rails to be shot down, the moment the first projectile isn't touching the rails, the new one rolls on... say... power it with a cordless drill battery and step the voltage up with a wallwart transformer? if we can make portable tesla coils... a rail gun doesn't seem so far fetched. granted, this post isn't using any technical jargon so you probably all think i'm an idiot, but i do believe that it's possible. my knowledge of rail guns is fairly rudimentary. any ideas? it would obviously be VERY low velocity... but if you were to make it stationary, you could upsize it and run it through a large MOT from a microwave, or a transformer from a UPS or something equally massive and... well... have a fullly automatic rail gun turret-y thing? yes?

240v to 75kv transformer, shell type? Double winding? Need sum help please!!!!!

Hello! So I found this transformer the other day, it's a 240v to 75kv here where it's gets interesting, it's a shell type, with two separate transformers I'm guessing. It has a input for 240v on each end, it has 1-5 taps but 1 is not used 2 is phase 3 is neutral 4 is earth and 5 is not used. It only has condanuity between 2 and 3 on 240v side. On the high voltage side it has only one output and no condanuity to the core or anywhere, So I'm confused. I'm wanting to make it in to a high voltage Jacobs ladder setup. I have a varic that is 240v and goes from 1v up to 280v on the wiper side it is motor driven. Can I arc between the two hv posts? Also both transformers are have the same phase in parallel.

high voltage from a large flyback transformer? Answered

For the life of me i cannot get big spark gaps from my flyback transformer. I did all the steps to find all the pins and i have a 600v electronic instant on ballast. Im using clothes hangers for the wires the arc climbs up and it is attatched to a laminated particle board. I need to have the wires really close to eachother for it to arc, but then it just arcs up and down about 1/4" if that.. ive tried positioning them all sorts of ways to try to get it to climb but nothing... i feel like the fbt should be putting out massive amounts of power but its not it isnt even getting warm when i turn it on...even left it on for a bit and no heat! Ive tried a couple different pins for the HV- And the one its on gets the biggest arc..is it because its on wood? If so what should i use? Or is it the clothes hangers? No idea but any advise would really help me out.

Safely add a Flyback Transformer to a an electrical fence transformer to make plasma? Answered

Hello, Just a few things you should know first: This is my first post on Instructables, and I am kind of new to electronics. I have a very old outlet powered electric fence charger that I recently took apart because it was broken.  I took out the transformer and hooked it up to the wall (110v 60hz) bypassing a large resistor and capacitor and was able to get a stable arc of plasma about 1/4" long.  As best i could tell the transformer does not have an internal rectifier so the output was AC.  As for the voltage and the amps I can't tell, The limit of my multimeter is 500v and it went past that even with the resistor and capacitor hooked up to it and the output voltage is not labeled on it. I am hoping to connect a Flyback Transformer to this to make a Jacob's Ladder and possibly experiment with some plasma. I do not yet have one but I am currently looking at a few on Ebay that are standard in Sony TVs. So i guess my questions would be:  Is it safe to connect a flyback transformer to it? Is it even safe to hook up 2 transformers in that manner?  Would it burn it out? And what kind of Voltage could I expect out of it? Would that kind or brand work well? Any help would be appreciated, Thanks.

High Voltage Flyback Transformer Pinout HELP!

I pulled out a flyback HV transformer from a CRT television set (I DO know of the dangers involved, and I'm VERY careful to discharge all caps and to short out the flyback).  But the problems is, I have a FB Samsung C31113D.  Very hard to find schematics or specs on.  Rather than fiddling with which pins do what (via battery and multimeter-which I guess I could do), does anyone know of a site that offers pintout schematics for different manufacturers?  I'm anxious to begin my project on building a Jacob's Ladder.  But without knowing which pins do what, I refuse to tinker.  My life is just too important. Is there anyone who may be able to help me out here?  Perhaps checking each pin with a battery is the only way to go, but I would like to avoid that if possible.  Also, what waveform does the FB  Transformer put out?  I've heard square wave, and I've heard D.C.  The only thing I have definitely heard is that sine waves tend to result in smoke from the FB. Thank you!
