Background: When a hard boiled egg is spun on a table, it rotates freely since the inside is completely solid. With a raw egg, the liquid yolk sloshes around and resists rotation. By using math and physics, we can analyze the rotational oscillation of an egg and determine the yolk consistency.

Objective: Design and build a device to determine how cooked a boiled egg is using non-invasive techniques.
Motivation: As part of our final year engineering course, we were tasked to create a mechatronics device of our choosing. This project was heavily inspired by Matthias Wandel and his boiled egg hardness tester.
Limitations: This prototype was developed in 3 weeks during school and has approximately 80% repeatability.
