The most ambitious and rewarding projects that I have worked on thus far include my Nixie-Tube clock, lathe design project and gear modeling project, which have each greatly improved my skill in relevant categories like 3D-modeling, circuit design, data analysis and prototyping of mechanical systems. Using modeling software, coding methods, new manufacturing techniques and experience with circuits in tandem with copious amounts of internet research, I constructed a decorative clock which displays time on cold cathode tubes. Similarly, I modeled my own lathe machine from scratch in Creo Parametric based on existing lathe technologies and have had to learn about many new precision machining techniques and tools in order to properly manufacture the lathe in my free time. While the lathe has required the largest time investment, I have learned more from my gear modeling project about the fundamental geometries driving perfect gear interaction and extreme gearbox requirements. I began each project without a mastery of all of the skills needed to finish it. Through execution of these hobby projects, I have been able to solidify and build upon my education, sticking with them to the end and finishing with new skills in my hypothetical toolbox.
