This Instructable will walk you through building a medium sized Tesla coil.

Step 1: DANGER

Unlike some other high voltage experiments, a Tesla coil's streamers can be very harmful. If you are shocked by the streamers, you will not feel pain, but your circulatory and nervous system can sustain severe damage. DO NOT TOUCH IT WHILE ON UNDER ANY CIRCUMSTANCES.

Also, I don't take any responsibility for you hurting yourself.

This isn't to say that you shouldn't get into high voltage though, its just that if you are planning for this to be your first HV project, its a little to involved. Instead, try out a nice microwave oven transformer, and be safe!
<p>Can a commercial capacitor be used? if so what would I look for?</p>
Remember that a tesla coil requires high frequency discharges to function, and only pulse-rated capacitors can achieve that efficiently. Do NOT use e-lyt caps or PFC caps for a tesla coil, they will burn out quickly or even worse - blow up. Theggekgroup has a good video on caps for tesla coil use, check that out.
<p>I searched for some high voltage capacitors, basically you have the following for up to 3kV:</p><p><a href="http://www.digikey.com/product-search/en?FV=fff40002%2Cfff8000b%2C340019%2C34001a%2C34001b%2C34001d%2C34001e%2C34001f%2C340020%2C34003e%2C3401b8%2C34049a%2C3800c0%2C380132%2C3801ec%2C38029f%2C3802a0%2C3802a1%2C3802a2%2C3802a3%2C3802a6%2C380306%2C380307%2C38038f%2C38042a%2C3804da%2C3804ef%2C380513%2C380514%2C38054c%2C38055b%2C38055f%2C380560%2C380561%2C380576%2C380577%2C38058f%2C380590%2C380591%2C380592%2C3805e2%2C3805e5%2C3805e6%2C3805e9&mnonly=0&newproducts=0&ColumnSort=1000011&page=1&stock=1&pbfree=0&rohs=0&quantity=1&ptm=0&fid=0&pageSize=25" rel="nofollow">http://www.digikey.com/product-search/en?FV=fff400...</a></p><p>If you need 15kV you can connect five of them in series like this:<br><a href="http://farside.ph.utexas.edu/teaching/302l/lectures/node46.html" rel="nofollow">http://farside.ph.utexas.edu/teaching/302l/lecture...<br></a>but then their capacitance will drop five-fold, so you'll need to connect several such chains in parallel. I managed to find somewhere that the capacitance of a home made bottle capacitor is around 1.8nF <a href="https://www.physicsforums.com/threads/how-does-a-salt-water-capacitor-work.501119/" rel="nofollow">https://www.physicsforums.com/threads/how-does-a-s...</a></p><p>And you can get the 10nF 3kV capacitors on digikey for less than 2 dollars, and on ebay for even less probably.</p><p>the commercially available capacitors that are for up to 15kV are called ultra-high voltage, like this one:<br><a href="http://www.digikey.com/product-search/en?pv14=671&pv14=1425&pv14=1426&pv14=1424&pv14=1398&pv14=672&pv14=1509&pv14=1299&pv14=1510&pv14=673&pv14=1513&pv14=674&pv14=675&FV=fff40002%2Cfff8000b&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25" rel="nofollow">http://www.digikey.com/product-search/en?pv14=671&amp;...</a><br>and they cost 58$ a piece.<br>So. surprisingly, you can't get much cheaper than the home made bottle capacitor, at best you can build one from 3kV ceramic capacitors for 10$ or so.</p>
<p>I've also found these:</p><p><a href="http://www.ebay.com/itm/10pcs-15KV-2200PF-222-High-Voltage-Ceramic-Capacitor-/300678659867?hash=item4601d83f1b" rel="nofollow">http://www.ebay.com/itm/10pcs-15KV-2200PF-222-High...</a></p><p>it seems that there are chinese ceramic capacitors that are not listed on digikey, you can find 10pcs 15kV 2200pF capacitors (each is like a bottle only it won't blow up) for 1.5$ a piece or so</p>
<p>Do you know what is the capacitance of your capacitor?</p>
<p>Some things are in your home already you just have to look..lol dont start ripping pvc out of your plumbing </p><p>addresses shortened for your convenience </p><p>have fun be safe</p><p>the parts not included you can find at your local junk yard and shopping store because they are much cheaper </p><p>pvc pipe (clear)(comes any size so you can get 1.5&quot;) - http://ebay.to/1FsbsfK</p><p>copper enameled wire- http://ebay.to/1KtvyFf</p><p>pvc adapter(1.5&quot;)- http://ebay.to/1JnyM9j</p><p>metal floor flange(1.5)- http://ebay.to/1FsdVXy</p><p>Spray Enamel- http://ebay.to/1LumToh</p><p>Bolts, Nuts, Washers Kit- http://ebay.to/1LuocDu</p><p>10 ft Copper tubing- http://ebay.to/1NKDa8B</p><p>mineral oil- http://ebay.to/1OPlYjg</p><p>lot of aluminum foil- http://ebay.to/1L4fBsH</p><p>hv Power source- http://ebay.to/1KyXOEu</p><p> http://ebay.to/1j7Hxj1</p><p> http://ebay.to/1KyYbPc</p><p>and if you want to use capacitors instead of glass bottles</p><p>http://ebay.to/1NRMjxP</p><p>or even </p><p>http://ebay.to/1V8jcdR</p><p>doorknob- http://ebay.to/1NKM85M (limited) </p><p> http://ebay.to/1FdHaxx</p><p>Happy Generation!</p><p>p.s i hope there is a day to celebrate tesla </p><p>hes awesome</p>
Its really good but it would be better if u focus more on the connections of each parts....
&nbsp;for the love of god do not use 6 snapple &nbsp;jars with a 15kv 30ma nst you will get about 10 min of run time out b4 1 or more blow!!! all 6 were leaking badly. i think ill try a serise/parallel with 12 of them
<p>Why do they leak? Isn't there any way to prevent leakage. Or how you know that caps are leaking?</p>
<p>they would leak at the top of the foil with streamers moving to the lip of the bottle at 15kv</p>
Its easier and more convenient to make a plastic sheet and alluminium foil capacitor.<br>
<p>But as i see from your picture that they are too far for arcing at 15kv if considering that you need 1kv per 1mm to break the air. Anyway is there a way to correct it?</p>
<p>there is far more then 1.5 cm gap! It was do to leaking. When it leaks you will see dim looking feelers bleed from the edges of the foil</p>
HOLY&nbsp;CRAP!!!<br /> <br /> I just fixed the Instructable!<br />
Bro could u help me but explaining how to do that in a video chat
Bro could u help me to do my project
how many volts will one of the snapple bottles produce?
lol!!! good thing you did cause I have 4 litle girls in my house, is it ok if i use 9 small mouth pint jars instead? <br> <br>(i only would have done 3) <br> <br>thanks alot for makeing these instructions. <br> <br>ps i couldn' comment on the right one so this is for DevCoder
Anyone interested in helpin me i just want how to connect all parts
Can i contact u or can u give me a.live video how to make it

I have a dought u told to connect 8 or 12 bottles right we can connect 6 of them as u shown can u plz tell how to connect 8 or 12 bottles . with picture
<p>What is nst?</p>
<p>No one knows.</p>
<p>neon sign transformer</p>
<p>Please make a tesla coil using 12v.Which is known as slayer exciter</p>
<p>Uhh, now that I look at this diagram again, wouldn't you want the capacitors in parallel with the NST and the spark gap in series?</p>
<p>have you tried lighting a fluorescent bulb? does it work </p>
<p>Finished my secondary winding, does the bottom of the secondary winding wire connect to anything or should I just cut it off flush to my pvc?</p>
it connects to ground.
<p>Thanks, I assume you mean a grounding rod outside or can I use a wire to the house ground?</p>
I am sorry for the stupid question but how do I physically connect the capacitors to the coil. Wouldn't using capacitors with alternating current cause this top cancel out? Could you very a close up picture of how it is connecting. Sorry about this, any help would be great, I am building one this summer<br>
<p>Great site here, I was trying to find out how to build one of these things but they all failed and never seemed to work properly. Just recently I found a site that helped me build my own tesla coil and also power my home utilities , if you want to find out more visit - http://how-to-build-a-tesla-generator.blogspot.co.nz/</p>
<p>If you are interested in learning exactly how to generate power and reduce your bill then this is the perfect resource for you! With the ever increasing costs of living, there is no better time than right now to stop throwing money out the window and start generating our own electricity. Check http://inplix.com and learn more about it.</p>
<p>Does the winding direction matter?</p>
Cuanto tiene que medir el tubo de pvc y el de cobre
<p>Also, what wire is used for connecting the NST, capacitors, spark gap, ect...</p>
<p>Also, how can I ground the primary and the secondary coil if they can't be grounded in the same area?</p>
<p>what is the &quot;1.5&quot; PVC screw-thing&quot; used for? </p>
<p>You should try to update your directions cause they are hard to understand and how long should are bolts, washers, nuts, wood and PVC pipe should be. Also what is a circular, smooth metallic object for the discharge terminal is what did you use ..maybe a metal bowl. But anyway thanks for making this and tell us were to go for the next Tesla Coil.</p>
