Warning I take no responsibility for any injuries obtained.
You are doing this at your own risk.
This is to give you the basic idea of wiring for a transformer.

I Will Be using a Microwave transformer.
 

Step 1:

You Need to find your self a transformer.
My choice is a Microwave tranformer.
You Will also need some tape, wire, switch, fuse and a wall plug
The  switch sould be able to take 10amps at 240 AC.
These can all be found in a microwave.

Step 2: Primary Coil Connection

Stat wiring Need to wire the phase wire from the plug to the switch and the neutral to the fuse.
These wires will now go to the Primary coil of the transformer.

Step 3: Secondary Connection

Now we needt to conect the Eath conection from the wall plug to the base for the transformer, We will add a secound cable from the base of the transfomer, This will act as the common Neutral for the high voltage side.
Now we  will add a connection for the phase of of HV side.

Step 4: Have Fun

Turn On the Switchs and you will hear a slight hum, Good sign now get the to Hv wires and touch them together to draw an arc if this works well done.
Brother the instructions weren't done well at all. Thanks, absolutely, for sharing.....but it was more like a poorly written "run through", especially knowing that the careless or improper use of these can kill.
<p>Aggreed, the poor spelling makes it barely understandable, instructiuns are extremely unclear, like if it was written by a child. This shouldn't be on this site, given high voltage is a very serious business. </p><p>I'd love to see this instructable in a rewritten, much more detailed and extended version though, don't misunderstand me.</p>
<p>&quot;If this works well done&quot; ???</p>
Right!?
<p>Wat Switch that you use </p>
<p>&quot;We will add a secound cable from the base of the transfomer,&quot;.. Where does that one go? To Earth/ground in your home / the wall plug or where?</p>
Fun for the whole family! coroner, undertaker, gravedigger, toetag printer, embalmer, hearse driver. Oh,and everyone be sure to&nbsp; sign the guestbook at the viewing of the body. I screwed around with a neon transformer 20 yrs ago, just be more than careful. It's like a loaded gun. One false move and pow!<br />
<p>Thanks for the advice</p>
<p class="MsoNormal" style="margin: 0.0cm 0.0cm 10.0pt;"><font face="Calibri" size="3">Yes it can be fun but they need to be careful, if they are beginners and have access to a Power Pack 12VAC would be a better choice than 240VAC</font></p>
So if I hook my MOT up to a 12 VAC supply, it will be a lot safer? I think this is just as dangerous, because I calculated my transformer that has 4KV output when 120 is connected, that at 20 VAC, it would still put out 640 volts.
Yes it will be a lot safer, but also make sure you have a current limiting power supply. I recommend about 5amps or less. This should give you about 100watt total on each side. This would leave you with about 0.1amps. Warning this can still kill you if not careful but is still a lot safer than having 4kv. Just be careful. It not the device that can kill you it is the user.
<p>Hi</p><p>I just salvaged a monstrous transformer from a Dia slide projector (Leitz 1960&acute;s). It is HUGE!!</p>
This is great, I think that people need a very simplified version where it shows black wire to black wire and white to white, how to solder the leads to electrical alligator clips. I could imagine maybe 5 more steps.
This is not fun,this is very dangerous........<br />
<p>The words &quot;Fun&quot; and &quot;Dangerous&quot; can be synonyms sometimes :)</p>
Actually, that <em>is</em> fun. Just be sure to wear your Faraday Cage suit whilst doing this. Less likely to shock yourself ****less.<br />
Hey pal did you find the fuse in the microwave? and could you possibly upload a picture of the wire with the fuse going to the transformer, thanks :)
can u do this jacobs latter stile?<br />
its not so bad, you should be worrying only if you would be messing with wires in basment standing in puddle without yoir shoes. Just make sure the shortest way through your body dont go through your organs. Few months ago i experienced 10kV 15A through my left hand two fingers, only damage was burned skin<br />
What were you using to generate that high voltage and current?
I was seting up powerful laser in lab<br />
Your connections look &quot;dodgy&quot;, and I don't see much /any consideration for safety. What happens if the HV wires weld themselves together?<br /> <br /> L<br />
If the HV wires should weld together turn it off and break them apart.<br />
Turn it off <em>quickly</em> before things start smoking?<br /> <br /> L<br />
The quicker you do it the less damage is caused to the transformer
Well yes, and anything/one else too.<br /> <br /> L<br />
I Should of said at the start that is dangerous and should be done with care and if possible do it with a lower current and voltage power supply.<br />
&nbsp;&quot;and the neutral to the fuse.&quot;<br /> <br /> Shouldn't the &quot;live&quot; or &quot;phase&quot; wire go through the fuse ?<br /> Neutral and earth are connected together either at the power station or the distribution box somewhere but anyway, if your fuse was to fail because of a fault with the transformer, because you have earthed the casing, the current can flow from &quot;live/phase&quot; line and through the case of the transformer to earth/neutral.<br /> <br /> Just fuse the live/phase line and NEVER fuse the earth.<br /> Stay safe !<br />
OH GODS!! DON'T DO THIS! YOU'LL DIE!!! SRSLY!!!<br />
&quot;Good sign no get the to Hv wires&quot;<br /> <br /> &quot;no&quot; should be &quot;to&quot;<br /> <br />
Sorry I Missed the &quot;W&quot; in Now sorry will fix it.
No problem, just was wondering what you meant.<br />
no he meant to say<br /> &quot;Good sign now get the two Hv wires&quot;
You might to wear protective clothing when working with one of these...&nbsp; I'm sure it would have no trouble killing you or injuring you.<br />
Gloves and Rubber Shoes Would be a good idea
