Control Panel:

To control the tesla coil, we built a control panel to allow use to safely operate the coil from a distance. The panel has a emergency stop, key lockout, engage button, alarm button, and fan switch. 120V power enters the box through a 12-Pin connector on the back of the box, it then immediately goes to the emergency stop switch, which is normally closed. From there, the power flows to the key switch and then is distributed to the "fire" switch, alarm switch, and fan switch. The key switch is normally open in the middle position. The fire, alarm, and fan switch are all normally open. The fire switch and alarm switch are both momentary and the fan switch is latching. There is also a voltage/amperage panel mount meter that is tapped of the power after the emergency stop switch.

Eventually, a raspberry pi system to log voltage and amperage data will be implemented.

Control System:

On the tesla coil itself, there is a one gang electrical box with a timer installed. Once the power leaves the wall, it goes into the electrical box and then into the timer. Once it leaves the timer, it goes to the control box. After it comes back into the electrical box, it is then distributed to the NST, the fan, and the alarm, respectively. The wire that runs to the control box and back is two electrical cords taped together and also ziptied.
