California Registered Professional Engineer, Mechanical — License No. M 41107 · Murrieta, California
Payson Labs is a principal-led mechanical engineering and mechatronics practice for teams that need thoughtful product design, motion and sensor integration, prototype sourcing, design reviews, documented prototype testing, and hands-on final assembly.
Walter Coe is a California Registered Professional Engineer (License No. M 41107) and BYU Mechanical Engineering graduate based in Murrieta, California, who works across the full path from early concept to physical hardware. His work centers on the practical middle of product development: requirements, CAD, housings, mechanisms, prototype parts, contract-manufacturer coordination, design reviews, test-plan execution, final assembly, and useful documentation.
A large share of that work is mechatronic. Walter has extensive experience with motor design and selection, servo and closed-loop motion control, drivetrain and mechanism design, and the sensor integration that lets a machine track its own position and state. That experience runs deep in sensors and robotics, and in the electromechanical packaging that keeps motors, feedback devices, and cabling serviceable inside a real assembly.
Payson Labs was built around a simple belief: engineering gets better when design decisions stay close to the bench. A model, drawing, or report should connect to the way the part will be fabricated, reviewed, adjusted, and assembled.
The practice supports product-development teams, prototype programs, and design-improvement efforts where disciplined communication and discretion matter.

BYU Mechanical Engineering Graduate
Lab
In-house 3D printing, limited bench rework, and final prototype assembly in Murrieta, California.
Working Style
Clear thinking, practical hardware, and useful handoff.
Bench-Aware Design
Design work stays connected to real materials, fastening, tolerances, supplier constraints, test access, and assembly flow.
Respect For Constraints
Confidentiality, documentation needs, schedule pressure, and manufacturing realities are treated as part of the engineering problem.
