I have recently been looking at a circuit named a "slayer exciter". From what I have read it is a form of SSTC (solid state tesla coil). I found a good video about it on youtube which you can find here. I have checked other versions of this question on this website but nothing seems helpful. I am using a secondary coil with ~800 turns and a primary with 3 turns. I have used the schematic from the video above, but since I don't have a lab power supply or any 9 volt batteries available to me, I decided to use a 5v usb connector to power the coil. I have completely replicated the circuit from the video and used all the same components (TIP32C transistor, 47K Ohm resistor etc.) However, when I power it on, I saw no output from the secondary (yes, the primary and secondary are wound in the same direction), and worse, when I probed around with an LED connected to a crocodile clip to ground, I saw no output from the resistor, but when I probed directly behind it, I found +5V. I also looked around the primary coil, which had +5V on it, and yet when I looked for the purple arcs from the secondary, I saw none. I even touched it and felt no shock. You may say: "but slayer exciters are not able to deliver much power". Well, I used my LED on it and it didn't seem to explode so that's not the issue.
(replace the 9v battery with a 5v usb power source)
I will try and get some 9V batteries but until then it would be very helpful if someone could tell me what I did wrong, or what could be the cause of the lack of voltage in the secondary.
- I am using a hand-winded coil, which I spent ~4H winding.
- The primary coil is not a perfect circle, more of a squiggly line circle, if that makes any sense.
- My usb sockets are USB 2.0
Thankyou in advance :)
