EDDIE & FRAN ENGINEERING

Engineering for
systems that move,
sense & power.

Eddie & Fran is a small engineering firm. We take hardware from first sketch to working prototype to production-ready design.

Specialties

Electro-Mechanical Systems

Actuators, drives, gearing and enclosures designed together with the electronics that run them — so the whole machine works, not just the parts.

  • Motion & actuation
  • Mechanism design
  • Thermal & structural

Energy Storage & Power Conversion

Battery packs, BMS, converters and chargers — engineered for efficiency, safety and the realities of heat, weight and cost.

  • Pack & BMS design
  • DC-DC / inverters
  • Safety & compliance

Precision Sensing & Measurement

Low-noise analog front-ends, calibration and signal processing that turn the physical world into numbers you can trust.

  • Analog & mixed-signal
  • Calibration & test
  • Embedded DSP

Automation & Control Systems

Firmware and control loops that make machines run themselves — reliably, safely and observably.

  • Control theory & tuning
  • Firmware
  • Test automation

How we work

Small team. Direct access. Drawings you can build from.

1

Define

We pin down requirements, constraints and risks before a single part is drawn.

2

Design

Concept through detailed design — mechanical, electrical and firmware in one loop.

3

Prove

Prototype, instrument, test. Real data decides what changes.

4

Manufacturing

Production-ready designs. Expert assistance into manufacturing and throughout production.
