Hi science peeps, interesting topic, i want to build a 12volt tesla coil combine it with solar and run 12volt appliances, not so dangerous i guess, any info on 12volt tesla instruction would be very much appreciated . I'm not much of a science guy but i want to play with a home project.

Kind regards.

Here back in the days tesla never had that crap so how Amazon? .anyway a spark from your lighter can do it .ive tried it and guess what no more scottish power for me no more bills .ive got the tesla coil running everything in my house .scottish power meter can go back to them no longer needed lol

Hi, Tesla peeps! Can I use ignition coils of cars instead of capacitors? Can someone help me build one that is in Solid State? I'll be helping my son build his (and mine, as well) first Tesla coil for his Science Project (one that could play .mp3 music from his iShuffle). After which, we could use this on New Year's day & 4th of July. This has to be done on or before December (2014).

Did you ever get any info on a solid state coil? After watching my fiancé enjoy the struggle and hate it so much at the same time, I was sucked in and developed an interest myself. Your finish date was "on or before December 2014" and Im curious if you guys completed the project or change to a different project? Im a newbie to all of this electrical stuff but you said it was for a Science project, leading me to believe that if he is still pre-HS grad, that I might be able to successfully understand it enough to make myself useful without extensive experience.

Hi SilverF. Nope, no info from SSTC (solid state tesla coil) from tesla peeps. My son (Jacob) wanted to have a different project. His classmates (upon knowing his project) wanted to have the same project. He wanted to have the "Jacob's Ladder" instead. I've found out from here that it's easier to build. You can check out the "Helix" type of Jacob's ladder. That, we plan to build!

I know that it has been a while since this was posted, and quite a while since I last visited this page, however, I feel the need to point out that this Tesla Coil does not work and following these plans is dangerous. The author claims that he has achieved sparks that were a few inches in length. Unfortunately, given his apparent understanding of his device and given how poorly it was constructed, even these mediocre results seem somewhat far-fetched. At the moment, I am trying to communicate with an admin to have this instructable temporarily removed until it is made to be up to par with the community standards of this website. Posting dangerous instructions about topics which one does not completely understand not only does you disservice by slandering your name, but it also puts the entire community at risk. Attaching warnings such as "IT WILL KILL YOU INSTANTLY THERE IS NO SECOND CHANCE!!!" does not help.
I highly agree, everything about this coil looks dangerous. Please, for your own safety, make a proper Tesla Coil, meaning not having the power switch next to the primary, which can more than easily kill you.

you don't even know what you're talking about.

This instructable needs to be removed before someone kills themselves.

Yeah, let's ban the universe from generating high voltages, lets change the laws of physics to limit the voltage in everytinhg to 5v, then after that lets change the law of gravity too, because gravity can kill you and there's no advice that gravity can kill, and after that let's ban water too, because we doesn't know what's in that water, let's drink just coke cola, we know that coke cola don't kill right?

Now THIS is why innovation and information suppression is alive and well - it's from some people believing that they are entitled to censor others because there is the possibility that a small handful of people *may* make a mistake, causing potential personal injury. Why do you feel that someone's lack of ability should ruin it for everyone else, especially those who CAN safely work with high voltages?

This is a situation where some feel the need to remove other people's freedom to make choices for themselves, catering to those who cannot (or will not) take responsibility for their own actions. If someone decides to build this project, that same someone needs to understand their own limitations before starting, then choose to build it if they feel they are within those capabilities - and does so at his own peril. Even those fully qualified to work on this sort of thing DOES SO AT HIS OWN PERIL, accidents happen to everyone.

I like the project, I am quite capable of working with high-voltage safely, why should I not have the the freedom and opportunity to benefit from this idea, merely because there are a handful of people that *MAY* attempt it and fail.

If someone is not qualified to drive a car, drives anyway and kills themselves, do we get rid of cars because this is a real possibility? Do we outlaw swimming because those who are inexperienced might drown? If the citizens of some countries weren't so quick to assign blame and sue another for their own misfortunes - a result of their own poor choices, clumsiness or simple stupidity - this "Nanny State mentality" would not be required. To shift the onus and responsibility for a hobbiest's safety onto the shoulders of those presenting the ideas and material to the masses, to the extend that it does, is almost unheard of in other countries. These people need to be aware of their own abilities or lack thereof.

And yet, prior to these last few decades of being legally responsible for others if they follow your suggestions, it was already a natural-developed tradition, out of common courtesy and care for his fellow man, that potential risks and dangers were pointed out in the interest of safety, that may not have otherwise been apparent.

I'm absolutely in favour of including a paragraph that clearly draws one's attention to areas where potential dangers and unique risks may be lurking within the idea or project, including personal observations or experiences, and suggested ways to minimise those risks. But it has gone WAY TOO far when it's required that someone sharing an idea has to nervously state he is not responsible, the publication is not responsible, the company and it's shareholders are not responsible etc. if you have an accident. GET REAL!! Handholding and babysitting that extreme and overprotective stifles innovation and creativity because many are too scared of being liable for another's actions... ruining it for everyone, including those enlightened countries able to enjoy such information.

*As an example (in an entirely unrelated field) - there exists an arrangement of huge, outdoor machines that move with such speed and force that you would be instantly killed if you got too close. That situation is prevented with elaborate gate and fence configurations of an exact height and grid spacing, including locking mechanisms and signage. In Europe, however, the exact same arrangement exists, but without the fences and paranoia - people there ARE responsible for their own actions and misfortunes. The machines?? Amusement rides at the carnival.

Sometimes people have to be able to skin their knees to understand that you need brakes on a go-kart. Making people walk through life in sheets of bubble-wrap and sewn-on mittens is not fair to those who won't fall-down-go-boom.

I'm not attacking anyone, especially you. I'm merely pointing out to those calling for the removal of this article that even the "scary and dangerous" projects deserve to exist for the overwhelming majority, and those who want to use them.

Everyone, please be careful when working with high voltages, and recognise whether or not you are experienced enough to safely build such devices. There is NO shame in asking for assistance from those who do have the experience needed to successfully and safely build and learn from this device, and others like it. If you are unclear about something, ask - but if you have the slightest doubt of your capabilities, try a similar project that is less risky to develop the skills you need to move up to a more challenging one.

Bottom line - BE SAFE - but the plain reality is, if you do mess up, it's your own fault.

Thanks for listening. Peace!

Do the direction, spacing, and shape of the primary coil matter? It sounds like you can "tune" it for maximum spark length but if I just set it up in a coil or helix with no measurements will it still produce something?

DANGER -- DANGER - DANGER

!!! THIS COULD KILL YOU !!!

PLEASE REMOVE!!!
so?
can i use a flyback transformer driven with a 2n3055 driver for a tesla coil
Any electrical project "could kill you" if you make the right mistakes.

Everyone has the right to have access to this material. Why remove it simply because there *may* be a few people that fail or get hurt as a result of not knowing what they are doing? That's called CENSORSHIP!

Drinking too much water can kill you, crossing the street can kill you, eating (and choking on) a meatball can kill you. Life is full of deadly risks every single day. It's ENTIRELY your job to choose for yourself those tasks you are capable of doing, in a manner that will minimise the risks.

It's all about choices, and living (or not) with the results of those choices.

Peace!
so can lots of things....you just have to know what your doing.

your secondary can also look like this
photo.bmp
Easier to make and almost as efficient
thats not a secondary, its a primary
i will not allow this
What is it that you "won't allow"?? If it's this project you "won't allow", it seems that it HAS been allowed for over two years. Just saying.
I just got 10 pounds of 24 AWG magnet wire for $90 (US). Call a local motor repair shop and ask who supplies their wire. They should carry 10 pound spools, or if you're lucky the motor repair shop might sell you some directly.

will it work with a flyback transformer?, also if it doese i need to know what wires hook to wat and how its getting electricity? batteries, mains?
This design looks frighteningly dangerous. I'm not sure on exactly what would happen once activated, but I'm sure an event similar to the climax of Raiders of the Lost Ark wouldn't be far from it.
or world domination...


MUHAHA!!!!!!!!!!

Hi,I built a TESLA COIL with 5kv 30ma nst.Primary coil made with 4mm
copper tube with 10 turns secondary made with 2inch PVC pipe.Winding
height 10.2inch(0.315mm enameled copper wire used) also made Capacitor
bank with 2kv 0.15uF polyester film capacitor.But the problem is my
Capacitor burnt several times but the coil works with LEYDEN JAR
capacitor.Why the capacitor burning??????


Please Help Me!!!!!!!!!!!!!!!
hii .... actually this is my first attempt to tesla coil ... i m doing it for my college project ... i use a secondary coil 63mm in dia , with wire .3mm thick and 1000 turns... my primary is made of 10 SWG wire with 6 turns with first dia being 160 mm and consequent turns 5mm apart .. i had ordered a transformer 220/4000V and 35mA ... i dont noe whether it is current limiting or not ... i made toroid using a 4inches aluminium duct .. 22 inches in circumference ... now a few questions :-
1) can i use a series of 400V capacitance for primary ?
2) what should be the value and current rating of my bleeder resistance ( connected accross capacitance)
3) how do i limit the current ; provided i dont noe whether my transformer can limit the current or not ... ?? if using a choke what would be a good value of the choke and its rating ??

4) how do i tune my tesla coil ... i have no access to occilioscope :( :(

thanx alot BTW for sharing your experience !!!
amazing1.com is WAYYY overpriced. Make your own parts and this will cost around 20 bucks
Or just use eBay, I working on a 4" Tesla coil that WAAY bigger than this, I already have all the parts just haven't put them together yet and I have only paid about $130.
hiii ..... i had a question .... can we wind the primary on a wooden structure ??? can the wood withstand the high voltage and current

@okura, the tesla coil is quite safe if built right, you need to reeducate yourself.

:O TESLA COIL??? Man...its the one way ticket to meet Tesla in person!! ''the power flows into the capacitor where it gets amplified then moves along to the spark gap" - indeed !!! Its time this killer coil is removed before it kills somebody.
i believe u were ment to say where the power got accumulated
