Guidance for Analog Sensor Prototype Development

Analog Electronics Consultant — Remote Guidance for a Sensor Prototype

We are building an analog sensing circuit and need an experienced engineer to guide us through it remotely. We do the bench work; you tell us what to do, what to measure, and how to interpret what we find.

What you would actually do:

Review our existing schematic and flag anything wrong or fragile
Give us clear, specific instructions we can follow at the bench
Tell us what to measure at each step and what reading indicates success
When something does not work, help us isolate the cause rather than guess
Improve our approach where you see a better way

Must have:

Good knowledge of Analog Circuit Design and real hands-on analog circuit experience
Strong grasp of AC behaviour: resonance, reactance
Grounding and noise discipline, working with microvolt-level signals
Good knowledge of Signal Processing

Useful:

Inductive sensing, coils, transformers
Lock-in or phase-sensitive detection
Audio-frequency electronics
Python with numpy

How we would work: you send instructions, we build and measure, we send back readings and photographs, you tell us what they mean and what to try next.
What we provide: schematics, bill of materials, acquisition and analysis software, and components already purchased.

Duration: 2 to 3 weeks, part-time.
