HTR Motor Controller V2

Teradyne — Nextest Division · Engineering Intern

During my summer 2019 internship at Teradyne's Nextest division, I designed and documented a motor control unit built for production use — working alongside a college graduate intern to take it from V1 prototype through to the refined V2. The HTR Motor Controller was real test equipment, not a class exercise, and it needed to be reliable, reproducible, and understandable to anyone who picked it up after us.

At the heart of the build is a commercial motor controller module — a black box unit with documented interface pins for all its features: speed control, direction, enable, and more. Our job was to read that documentation and build a practical front panel around it: wiring in switches, indicator LEDs, directional buttons, and speed selectors that gave a technician clean, intuitive access to everything the controller was capable of.

Misc. Electrical / Mechanical Fixtures

Alongside the HTR work, I assembled various other electronic fixtures from kits — crimping connectors, managing wiring harnesses, and keeping cable runs clean and serviceable. Each build came with existing documentation that I worked to improve as I went. Building and refining that documentation in parallel with the HTR project gave me a clear picture of what made a design truly reproducible: a complete kit with hardware, wires, connectors, and a wiring schematic tight enough that anyone could order the parts and build it from scratch.
