I'm going to be honest, I am a COMPLETE newbie when it comes to electronics, I have only been tinkering/creating small circuits for a month or so. I need help with my flyback transformer wiring. I am being EXTREMELY cautious when it comes to safety considering I have basically 0 HV experience.
Anyways, a few days ago I was able to get a 9v Automotive Relay flyback driver to work, only creating about .5-1.0 cm arc. Today I finally got my 555+510 driver to "work". However with my 555 driver I am only getting about the same arc distance as I was with the 9v relay. The frequency is much higher, but I am still hoping for something I bit more than a 1 cm arc. My final goal in the project is to have a 16 bit DAC plasma speaker, however that is far down the line. For now I am just looking to get a 555 driver with a few inch arc. Can anyone go through and tell me what you think I can do to improve?
Parts list:
Radioshack 555CN timer
2x 10k POTs
2x 1k Ohm
100 Ohm
330 Ohm
16 Ohm 7W
.01 uF Ceramic Cap (103)
C1815/C2827 (I get a more consistent/stronger arc with the 2827) transistor used as a MOSFET driver
IRF510 MOSFET
Here is the schematic I am using. Only thing differing between mine and the schematic are the NPN transistor and the 10 Ohm resistor to the MOSFET gate (mine being 16 ohm).

I have run the breadboard at 3 different (working) voltages. 12, 15.3, 17. I always run the FBT at 12v. When I tried hooking the breadboard and the FBT to 24v my old MOSFET flew across the room... literally.
Anyways, some help or constructive criticism would be greatly appreciated!
