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

Jacobs ladder with ignition coil?

I got an ignition coil From a motorbike repair shop for free, I cant find a way to use this to Build a Jacobs ladder. I think it works as motorbikes have it for producing sparks that pass through air. Any ideas to help me in this build is appreciated. Should i use DC but i don't see two points for connecting the wires from a battery. the model no of the ignition coil is "Yamaha SAP-1737 "

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.

Can you make a Jacob's Ladder into a speaker? Answered

http://www.amazing1.com/jacobs-ladder.htm#JACKSING10 So Information Unlimited has a Jacob's Ladder that apparently generates not just crackles but high fidelity music or whatever sound you pipe in. 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.

Creating a Jacob's Ladder with a flyback transfomer and a power supply Answered

I saw an instructable on how to create a flyback transformer with a small battery and was wondering if I could substitute the battery for a power supply. I'm not to sure of the devices in that circuit could handle the power of the power supply without frying and I'm also still wondering why it's necessary to have the circuit there in the first place. I am going to use this circuit to power a Jacob's ladder.

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....

Does the size\weight of an NST matter? Answered

Hi everybody, I have at work two old school iron core neon sign transformers. They are both rated at 10KV 100mA. The thing is, one of them is only 2/3 of the size and weight of the other.   Assuming they are both in good condition, would there be any difference in performance, durability, reliability or whatever between the two?   I want to build a Jacobs ladder, and was wondering which one would work best... Thanks for the help!

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!

Flyback transformer question.? Answered

I have an urge to play with high voltage.  Maybe a Jacobs' Ladder, maybe a plasma speaker, maybe just make sparks and burn myself. Does the make / model of flyback transformer matter?  Or do they all connect the same way? For instance, would you recommend this model?

What Capacitor size for a 4 stack MOT Tesla coil?

I have just bought a 4 stack MOT transformer in a case and oil filled it says 8.6kv on it but no idea of amperage, I have a large variable ballast and hooked it up to my test jacobs ladder and it pulls about 10amp and really fires the ladder well. My coil has a 6inch by 29inch winding on the secondary and a Synchronous spark gap (200bps) but I cant seem to get a decent spark off it I have an MMC of 44.0nF @20kv at the moment

What is the difference between These two transformers?

I hooked up a MOT to a wall circuit and made a Jacobs ladder. Wouldn't jump the gap on its own but arced really long. The smaller wire coil lit on fire, why?(second q) so now I'm using an air ionizer transformer and it won't do long arcs but it jumps gaps an does an awesome lol light night show. Why are thes transformers so different?

Disassembling a CRT and getting the flyback

Hello! I'm getting a bit tired of playing with disposable cameras... there's only so much you can do with them. Well, I acquired a CRT, presumably from an oscilloscope, a couple of weeks ago and I want to get the flyback out of it (and figure out how to use it) so I can make a Jacob's ladder or Tesla coil. Does anyone have any ideas on how to proceed? Here are some pictures.

Hey Guys,I need some help making a project for school

It needs to have at least 1 555 Timer within it. I was thinking of building a jacobs ladder with a 555 timer or if i could get it working perhaps a sonic pulse generator. Want something interesting and that won't take more then 7 weeks to build. Would it be possible to make a Cree Light and mod it to turn off after X amount of time? I'm just struggling to find idea's as our projects must be able to run off a 12V Battery or less and we cannot make anything dangerous. IE Rocket Launch Controller etc.... Thanks

The main Problem I can see is creating a vacuum inside the bottle . as I don't have a vacuum pump. Does anyone have any tips on how to create a vacuum inside the bottle? Also would an inert gas work instead. Any help appreciated  Thanks Ben

Simplest way to make an LED flash (part of) the Fibonacci Sequence? Answered

I'm trying to figure out if I can make one (or possibly several) LEDs blink maybe the first 15 Fibonacci numbers. Wonderfully awesome (but unnecessary) would be if I could also have it emit a sound (loaded from my computer) at the same time, in sync. Would something like a 555 timer work for this, or is that silly? Would that also drive the audio? What is the simplest way to do this? My experience with electronics is very, very basic - nothing beyond playing with LEDs, soldering/unsoldering components, wire splicing, a super-simple Jacob's ladder, etc. Is this project too advanced for the time being? I'm not asking for the schematic to be built for me, just some direction - I don't know what I'm doing here. Help?

Stun Gun Mod Suggestions/Tips? HV Power!

The 2 images are the type of stun gun parts I have, I believe its a spark gap igniter one but m not 100% on that as I would rather leave it in the cardboard circular case unless I get confirmation it could be modified. What kinds of projects could this be used for, I'm pretty sure its DC powered and attempted putting the outputs to curved metal electrodes for a Jacobs ladder but arc stays in one spot after many adjustments.  Ive only worked with HVAC with an unrectified flyback for plasma globes. Anyone have any suggestions on what to pump this badboy into. P.S. Using 2 metal screws from an Xbox 360 and putting them very close together makes a very nice whistle to it, :).

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.

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!

Cell phone motor power?

I have so many projects going on in my head that I am surprised there is room for anything else.  Heck I have plans for a Jacob's ladder, Tesla coil, perhaps a coil gun but who knows.  Well for quite some time I have also considered a vibe-bot or whatever you call them, the ones built with pager motors.  But since this is not too exciting to some people it is not something I have jumped on doing.  But I came up with a new twist today on the vibe-bot that I would like to try.  I do not want to give away too many details here because I would like to keep it a surprise if it works.  But I do see one possible problem with what I want to do and that is weight.  The parts I have already weigh in at 26 grams.  I am not sure how much the rest of the parts are going to weigh at the moment.  But I was wondering what you think the weight limit for a cell phone motor is.  I know that some cell phones can weigh a bit but I have no idea what the weight was for these cell phones since I did not have the scale at the time I tore them apart and would not have thought to weigh the phone anyways.  Thank you for your insight.
