A trip I took after finishing undergrad. The Google route shown below only approximates my route. All told, I rode 4500 miles over 90 days from Seattle, WA to New Orleans, LA. That averages to 50mi/day, but the beginning and ending mileages were closer to 25mi/day and 75mi/day, respectively. There was one 100mi day (a century) and rest days roughly once per week.

The goal of this project was to design a simple mechatronic device that undergraduate students could code for a final class project. All of the electrical layout and mechanical parts are provided to allow for quick assembly of the physical device. The challenge is in programming an LED array, resistor ADC, and two servomotors to work in sequence such that an operator can input candy and have it sorted by color. State machines suddenly appear useful practically when presented with managing the logic for such a device! An inherent data analytics problem also exists in how to train the device to recognize colors based on sensor measurements. I would love to see someone make a hardware training sequence that first samples many measurements of varying input candies and then decides for itself how to cluster!

This project was conceived and executed independently of CookieBot, but still makes an awesome conceptual connection for adding capabilities for color candy printing on that project!

Assembly drawings were made as instructions for both soldering together the light sensor and bolting together the final assembly.
