I believe I have the power source problem is mostly dealt with but there is still the concern on what MOSFET to use, it must be high power and extremely fast switching, and how much I’m expecting to need the resistor to stand up to without burning. I will definitely consult a local professional...

I guess all I can comment is, the pictures you saw before were incredibly messy and certainly unsafe. Once the series vs parallel problem was worked out I fixed everything before ever applying power again. The Tesla coil at the Griffith Observatory has millions of volts for output and is at...

I understand your concerns and take them seriously, especially since others will be around this apparatus. I will not connect directly into the AC mains but I was planning on using the 120 volts that is standard in most outlets using a proper transformer that I have acquired. The connected wire...

Sorry that second video was supposed to be this:

Right now I have 51 volts going into it and the transistor doesn’t even heat up. The only reason for more power is to have a larger discharge then this: Also I WILL add a top load I have no intention on killing myself or my electronics. Here are my references The second person uses a similar...

I was lead to believe that as long as the primary coil is rated to handle the voltage and the parts can handle the input then the circuit will be fine. I was going to use two high power mosfets in parallel and have the resistor go from 1/4 watt to 10-15 watts.

The error that prevented it from working was I wound the primary the wrong way, opposite of the secondary, and so the leads had to be switched.

I need to use this coil in a demonstration later in the week. I am going to supply 120 vac from an electrical outlet but I am not sure what MOSFET transistor to use and I don’t know the exact number of watts the resistor will need to withstand. Any suggestions on parts or even links on where to...

Ok thanks for the help everyone the circuit is working and everything is safe. I have covered all open wires and ensured even discharge to the batteries I was using. I have a proper power source now and there is a grounded rod to collect unwanted discharge and keep it away from the components...

Ok so the transistor wiring is not touching, sorry for the awful picture and angle, the schematic and instructions I fallowed came from . Now in the video no explanation is given as it is done and if you read the comments he states that he actually uses a 180 watt power supply with 40 volts and...

One quick update... I used a 15v dc electric train transformer that I had lying around, the led flashed for a second and then went out and the transistor got very warm. I’m not sure if the transistor is burnt but the led almost definitely is. Any way to tell if the transistor is still good? How...

Yes the circuit is correct, thanks for the input I will definitely work on the voltage and check the wiring to allow for ocilation in the coil.

In the picture it is not connected but when connected nothing happens. The coil doesn’t light up LEDs or fluorescent lights even in direct contact and no visible discharge comes at the top of the coil with or without a top load/toroid.

I am sure that the batteries are connected properly and the transistor gets warm when I connect power to the circuit so energy is flowing. How do I switch the polarity? Do you mean the by the small coil, the thick wire or the copper wire?

Here is the circuit, I replace the 50kohm resistor with the potentiometer. I’m
