2.131 Group Project - Combination Lock Cracker

Second version of the combo lock cracker hardware.

As a part of MIT course number 2.131 - Advanced Instrumentation and Measurement, I worked with Ben Peters and Gina Zak on this final project. The goal of the project was to characterize a system through mechanical perturbation. Ben focused on design and development of the mechanical systems, while Gina and I worked on electrical systems, algorithms, and implementation in LabVIEW. Check out the final paper here.
