Statement of Purpose
Our project this semester will be to build a musical tesla coil. The goal is to have a device that is able to sit on a desk, powered by a wall outlet using an AC/DC adapter. It will have a 3.5mm aux port to input sound and the output will be a spark coming off the tesla coil.
Background Research
We will be using a video from Keystone Science[1][2] to help guide in the construction of our tesla coil. We may try to modify the coil to produce a louder sound and design an enclosure that showcases the corona.
Block Diagram / Flow Chart
System Overview
The left diagram is our high-level block diagram. We will be using a mobile device, with possibilities for adding a capacitive touch control later, to produce our sound input. The driver circuit (pictured right) will up the voltage of the signal and allow us to create a corona with the tesla coil.

Possible Challenges
This project is the first foray into high-voltage electronics for any of us, but we should be able to handle a project of this size. We anticipate that finding the correct MOSFETs and transistors to handle the voltage will not be easy, due to the chip shortage.
