I made a Slayer exciter according to the schematic below.

I have done about everything necessary for it to work such as sanding the bottom of the secondary.

I have 2000 turns on secondary, and 7 on primary. I am powering it with 18V DC. It is powered from my power supply. I notice on my power supply that no current is being drawn from my supply when I power it.

I have an Arduino in the schematic to play music to it.

At the moment the wire going from the Arduino to the actual primary isn't connected in my actual circuit, while it is shown as so in the actual schematic.

Here's the schematic:

  • \$\begingroup\$ According to your schematic, no current flows through the primary. I suspect that the main problem could be due to the number of tip31's in parallel that the base resistor is too high to even start to turn them on. As well, I wonder if there is enough feedback current to turn the transistors off and to overcome the bias of the base resistor. \$\endgroup\$ – Kartman May 13 at 12:49

  • \$\begingroup\$ You have used insulated wire on the coils, haven't you? \$\endgroup\$ – Transistor May 13 at 22:19
  • \$\begingroup\$ @Transistor I'm not sure what you mean by that. \$\endgroup\$ – Comyar D May 13 at 22:24
  • \$\begingroup\$ Is your wire insulated or just bare copper? Is there a clear varnish-like coating on it to prevent the turns shorting out? \$\endgroup\$ – Transistor May 13 at 22:41

Turns out the tip31c was burned, and the primary was shorting to the secondary.
