About

Nathan Jones · Founder

Engineering depth.
Educational clarity.

LightTurtles, LLC is an embedded systems consulting and education practice focused on building reliable, understandable, and well-architected hardware and firmware systems. The work spans low-level embedded firmware, system architecture, digital logic, and hardware/software interfaces—always grounded in practical constraints and real deployments.

Founded and operated by Nathan Jones, LightTurtles blends professional engineering practice with a strong emphasis on teaching and technical communication. Whether developing firmware, designing systems, or creating educational content, the goal is the same: make complex systems work correctly—and make them understandable to the people who build and maintain them.

⬡

Deep, Practical Experience

Fifteen years of leadership and engineering experience across industry, academia, and the military—hands-on with firmware, hardware, and system design.

⬡

Education-Driven Approach

Every design, document, and system is built to be understood— not just to function. This improves maintainability, onboarding, and long-term success.

⬡

Real-World Constraints Matter

Experience with performance-critical, resource-constrained, and real-time systems informs every architectural and implementation decision.

LightTurtles exists to design embedded systems with rigor and clarity—and to help others learn how to do the same. The mission is to bridge the gap between theory and practice through thoughtful engineering, high-quality documentation, and effective education.

Areas of Expertise

What I Do

Firmware Architecture

Firmware that's hard to read is usually hard to trust. My background spans layering design, state machine structure, memory ownership, and scheduler organization—the foundational decisions that determine how maintainable and reliable a codebase stays over time.

Debugging

Debugging at the hardware/software boundary is a specific skill. I understand how timing, memory layout, peripheral state, and interrupt behavior interact—and how to isolate faults that don't show up in normal testing.

Board Bring-Up

Board bring-up requires knowing what "not working" actually means. I'm comfortable at the hardware/firmware boundary: reading schematics, probing power rails, interpreting oscilloscope traces, and systematically isolating whether a problem is in the silicon, the layout, the firmware, or the configuration.

Hardware Security

Hardware security is easier to overlook than software security—and often harder to fix after the fact. I have hands-on experience with ChipWhisperer, side-channel analysis, fault injection, debug interface exposure, and firmware extraction: the attack surface most products don't audit until it's too late.

Firmware Tooling & Developer Productivity

Firmware that can only be tested on real hardware is firmware that's hard to develop confidently. I understand how to design HALs for testability, build CLI and simulation infrastructure, set up unit test harnesses, and add logging and telemetry that makes bugs visible rather than hidden.

Get in touch →

Digital Logic & Computer Architecture

Understanding digital logic and computer architecture is what separates embedded engineers who guess from ones who know. I've designed and taught this material—and know how to make it concrete for people who need to apply it, not just pass an exam.

Get in touch →

Technical Training & Curriculum

Teaching embedded systems well means explaining not just the how, but the why—and knowing which details matter at which stage. I've developed curriculum at the university level, run workshops at hardware conferences, and written instructional content for engineers at all experience levels.

Technical Writing & Documentation

Technical writing is where clarity about a system becomes visible. I've written for EmbeddedRelated.com and DigiKey, and understand what it takes to explain hardware and firmware concepts to audiences ranging from beginners to working professionals.
