MINI TESLA COIL

Step 8: Power source

if you spend money on this project it will most likely be the power source. this tesla coil will only run on AC power, iv'e tried it with DC and it was ether very poor or nothing at all.
this is what i used http://www.instructables.com/id/MAKE-A-HIGH-VOLTAGE-SUPPLY-IN-5-MINUTES/, it was the only high voltage AC power supply i had.
or you could always use a NST, i didnt have the money to buy one.

so how about 70 volts alternating current, a kila volt that is one thousand volts right?

[Jimmy Proton]

70V is way to low, for this one you need at least 1kV, the supply I was using was about 2kV.

[zanki_kitsune]

yes but 1kv is after the transformer, that increases the voltage, when really your power source was likely the 110-120 volts of a house outlet unless your the European 220. so instead of 120 how about 70v before the transformer is what i was asking. wich i know is entirely possible now. just not as powerful.

[lug big lug]

well it depends on your transformers output.... thats all that matters

hii !!! i have secondary on a 2.5 inch PVC and my toroid is made of aluminum duct . now i want to know whether there is any electrical connection between these 2 . how should i mount the toroid on the secondary ??

[Jimmy Proton]

You connect the wire on the end of the secondary to the toroid and mount it on top of the pipe, make sure there is no metal in the pipe though.

[sudhanshu529]

so i have to connect one end of the secondary to the toroid ? what about the other end ??

[Jimmy Proton]

The other end goes to ground, but I didn't do anything with it on this one, just left it there.

i plan on making a smaller one than this, besides people can get several hundred thousand from standard wall outlet, 120 volts, and i intend to have a high voltage transformer, which you seem to be not using, i will not use a flyback transformer, because f expense, are not those for makeing direct curent into alternating current? i plan on making many of my own capaciters, and where can anyone get a 1kv power supply without breaking the bank, all i need is a tesla coil to produce tiny sparks, the generator alone can produce a quarter of a centimerter sparks already, so a smal tesla coil made well enough could probably get me something visable, it is my first tesl coil, and all i need is it to be at least 6 inches tall, and produce some sort of electrical discharge. do expect everyone to make the exact same one as you?

[Jimmy Proton]

Still, even 100V is to low for that, 500V is more of what you need, maybe more. You can use an electronic lamp ballast probably, the one I have is 580V and I use it to power my 100kV flyback. I have herd that you will probably get AC output from a DC input from a flyback which is the only explanation why I can use a flyback to power this. By this way, this is poorly made Tesla Coil and creates very small
sparks.

and as well i intend to make mine better improve it ad a toroid, to increase spark production experiment with making bigger sparks, and also something such as a neon sign transformer make it quite a bit more powerful from standard house electricity, with something like that does it have to be standard socket power to power the neon sign transformer. something funny just happened that i had to put in here, i misspelled something and when i used spellcheck one of the suggestions was "typo"

[aweis]

wait electonic lamp ballast is that used in some way to produce enough electricity, to power the capaciters, wich actually where the power is converted into hiugh voltages from, so i would technically be able to make a small maybe 6 inch tesla coil work, it is just the wind up for the electrical discharge may take a while the first time and have more space inbetween,

[physicsnerd]

how much power does this power source have to be? will a class 2 transformer that outputs AC 9V 300MA work?

[Jimmy Proton]

No, it must be at least 2-15kv.
