Small tesla coil

[alfareifaldy]

what capacitor bank you use, salt water capacitor, multi miniature capacitor, or a doorknob capacitor ?

[teslina]

@alfareifaldy 3.6 nF MMC (multi mini capacitor)

[DX721]

beautiful!

[doorm4k3r]

I like it. I've got quite the same coil, but i use a different kind of transformer. How could you touch it? U just grab the steel thing, and the voltage is dividing in your hand's surface? May i will try this, but my coil runs at 180W and i'm afraid:D

[teslina]

@doorm4k3r I used an ignition coil, drived with a dimmer and a 8 microF cap. The setup is under 50 W I think. It is safe. Do not touch the sparks at 180 W, it can be painful. Just use a metalic rod connected to earth through a wire.

I bet you won't lick the ball...

:-p

[kiriakoskakos]

i cant find your page on the net is there anywhere else i can get information?

[teslina]

@kiriakoskakos : The link to my sites is on the channel home page.

Go to livvasil section and find SGTC contest thread.

[hyperidiot34]

ooh can u touch the ball thing

[Xadreos]

How did you build that?

[teslina]

@Xadreos All the informations are on my site. Search for teslinasite on net

[Haku1234567890]

Hell yea, thats what Im talking about

[codex653]

how did you make your topload? it looks like something with foil on it but i'm not sure

[teslina]

It is a floater ball from a closet reservoir covered with alu foil (around 7 cm diameter).

[mtdeezy]

k so i hav this telsa coil thing but its in a glass ball i took it out of the ball and its got this chip and stuff and the long wire tht goes up to the center of the ball. so if i plug it in ant turn it on can it be dangerous or is it safe? its not tht big. it cost lik 20 bucks

[teslina]

Your "tesla coil thing" is a plasma ball. If you get off the glass ball, you will not have air discharges, just a bit of corona maibe. If you touch the terminal, the arc will burn your finger, so pay attention, it is not safe.

[00011theman]

@teslina i did it before but i use plyers to touch it and i put a towal between the plyers and me but thew gasses in it small like s***

[jragomaster25]

how did the tool not shock you? is there rubber insulation on it or what?  please reply

[teslina]

NO, it is not insulated, but the tesla coil is under 100 W power. I feel some tingling, but it is not unconfortable.

[jragomaster25]

good because i was afraid of building one because i hear how it amplifies the electricity so i wasnt sure if it would be leathal if i got shocked  thx

[jessekarate08]

i did this once... i died tho

o ya there is no OJ in hell ,just a heads up

[zezimashock]

i made mine one's so stronge that when i had a screwdriver it arced form the screwdriver to my hand,

beleave me that hurts :P

[Saltyfries]

How would it work on 110 volt mains? What modifications would be needed? I could put it on 220 volts but it would be easier to plug it into a standard US 110 volt outlet. Thanks for taking the time to post info like this.

[teslina]

The setup is the same, only the dimmer has to be for 110 V. To get the same HV output you can use two ignition coils with the primaries in antiparallel and the secondaries in serie. But it would work with only one ignition coil as well.

[lamp0xe]

did you put your caps in parallel or in series

[teslina]

I used three cap strings in parallel (1.4 nF + 1.1 nF + 3.3 nF = 3.6 nF)..a lot of little caps in a MMC type primary cap.

[Slu1982]

Nice tesla, u can touch it finger :) come to me

[jovicakluk]

check my 4 cm mini sgtc out

[jaa93997]

nice design, but i see you stole your moms dish dryer

[prototype9000]

woudl you mind giving some specs like the turns on the secondary wire size and primary turns can figure outthe rest for myself

[teslina]

Look on yahoo for "sgtccontest", from the step 2 to step 5 (final setup)

[ErenSGR]

Hey that looks awesome, really and it is quite small too.

[xeronicus]

What are your output ratings on that?

[teslina]

4-5 cm streamers, 13-14 cm arcs. Current:unknown, voltage: unknown

[Casew2]

Actually, you can make a rough calculation of the voltage based on the arc length. The dielectric strength of air is about 3,000,000 volts per meter. This means that your coil was generating anywhere from 390,000 to 420,000 volts!

[teslina]

I dont think so. The DC calculations do not apply to high frequency discharges. At 400 kV I would have tens of meters of arcs. I suppose that the output is around a 20-30 kV at 1 MHz. Beacuse the oscillant process involved the streamers are emitted in short RF bursts and "grow" function of primary cap energy and the number of bangs per second (BPS).

[warhawk023]

are you just holding that wrench? or is it grounded

[teslina]

I am holding it and it is not grounded. My body "acts" as a ground for the arcs.

[SoopaDude]

looks like a vandagraph generator without the glass casing

[bladedragon544]

how dous a tesla coil worck

[hahapwntn00b]

How are you driving the ignition coil? The cheap light dimmer + motor run cap, or are you using an actual solid state driver?

[teslina]

It is dimmer + motor run cap driven: 1000 W dimmer, 8 microF @ 1 kV cap at 220 vac from mains.

[hahapwntn00b]

Nice! I'll have to build a clone of this for my school demos. Thx!

[bffb]

OOOhh yeah, great stuff! Nice sparks you've got!! What kind of caps did you use? Im want one for me :)

[teslina]

3.6 nF FKP (foil-propilene caps).
