I thought as well that the diode is there due to AC output. That's why it's reverse biased. I don't understand why I should reverse the diode, it would only light up and had no function at all.

And no, I don't have. But my bought Tesla coil used to mess with my screen, mobile, etc. This one doesn't do any of these.

I think what I want to do is to buy proper copper cable, around 0.3mm, not 0.1mm, it's very thin and high-resistive, considering I have around 500+ turns there. It will be way easier to wind the coil which such a diameter. I would not have overlapping layers, at least. That will be for my secondary. Also, I will buy some 0.8mm copper wire as my primary coil. I will add more turns to the primary so I can kick the inductance much more. Also, I have found this TIP35C high power, fast-switching NPN (handles at least 5MHz). It allows to pass 25A of currect through collector and also accepts 150W of power.

Is everything OK with above?

 

Hello,

Have a look at this site:
https://steemit.com/technology/@elektr1ker/tesla-transformer-slayer-exciter-circuit
It will explain the function of the diode.

So basically the connection I saw in the schematic was correct, I don't know exactly someone wanted me to switch the polarities of the diode. One more question, tho. Do you have to remove insulation from the secondary coil at the top where the arcs come from? Because I haven't done that so far. I did in only at the bottom of the secondary where the wire is connected directly to the transistor.

 

The diode is right way I made about what the TS has Mine did work it just not as power full as what they show on youtube

I understand and thank you for your schematic and time, but I wanna make this Slayer Exciter schematic working as I have the most components already home. So it's a way easier for me to build.

 

I think the circuit itself could work but there's a problem with my secondary winding, as I mentioned before, I winded it in a very poor way, overlapping layers, so thin wire.. etc. Immediately when I power it from my 9V battery, transistor gets hot. I think it might switch fast, but the output is very low due to badly winded secondary, not even enough to excite the fluorescent and create plasma.

Also when those layers are overlapping (they are not overlapping in parallel to each other), some wires cross the whole secondary in 45 degrees.. which might lower the field because they cancel each other, thus become very unstable. This is my opinion why it's bad and should be redesigned all over again.

 

Id say your nail on about the coil

 

Do you have to remove insulation from the secondary coil at the top

No! Only at the connection points. I also thought the LED was reversed until I noted its connection to the coil and was unsure. I would also wrap the secondary winding tightly around the primary with the coils widely spaced apart to increase the flux density.

Back in the day of making real Tesla coils, not these faux coils they call Tesla's today, the trick was to wrap the secondary with a string next to it. To keep a space between the wires of the secondary.

Using a 9V transistor radio battery for something like this is a crap shoot. Is the 9V battery fresh?

I don't understand why people today call these coils Tesla coils? Tesla is probably spinning in his grave over it.

I think it won't help. Would you like to see how my winded secondary coil looks like? It's terrible.

I know, the battery will last like for 10 minutes, if not less. I should power it from the outlet with 12V adapter.

I thought the diode was reversed and was who told you. I also missed the coil connection, so apologize for posting misleading comments.

It's ok, at least you tried to help, that's what counts.

What do you mean wrapping the secondary to the primary tightly? Am I supposed to take one end of the secondary winding (the top one) and wrap wrap it around a secondary, or what?

 

The secondary winding should be layered in contact with the primary winding. Your design is for 3:275 so it needs to be 3 turns on the secondary and not just the one shown in your photo. As someone else mentioned the 275 turns should be laid tightly without crossing until you reach the end and come back with another tightly laid layer. The better the coil wires are properly laid the more efficient the coil will be in transferring energy. Shortbus' using a string spacer on the secondary is a good idea. Nice, neat, no crossover except starting a new layer and if possible lay the new layer in the "groove" between the wires of the layer under them. After done and tested, for permanence the coil can be soaked with lacquer and tape wrapped for protection after drying. Preferably the primary and secondary will be nearly the same length even if more spacing used on secondary but don't stretch it out to widen it too much. Hopefully, someone else will advise you as to core material (if any other than air), optimum length, and diameter.

Yet another reason that the Tesla name is wrong for this type of coil. More of a self oscillating induction coil that a Tesla.

I got it now

 

Well I made a better coil figure Id post it here I made a 1500 turn coil 24 inch long 1-1/2 wide about 2300 feet of wire LOL
Here a picture


And little video
