What We Build

Full-Spectrum Hardware Consulting

From first sketch to production-ready design — covering every layer of the hardware stack. Engagements are structured to match where your project is right now.

Tier 1
Feasibility
Technical review of your idea. Walk away knowing if it's buildable, at what cost, and what the real risks are.
  • Architecture review
  • BOM cost estimate
  • Risk & timeline report
  • Technology recommendations
Tier 2
Prototype Development
A working, testable prototype with complete documentation. Everything needed to raise funding or start pilot production.
  • Schematics & PCB layout
  • Firmware development
  • Enclosure CAD & 3D print
  • BOM & assembly docs
Tier 3
Production-Ready Build
Design reviewed and documented for handoff to a contract manufacturer. Includes supplier research and basic pre-compliance guidance.
  • Design review for manufacturability
  • Test jig & fixtures
  • Supplier research & BOM
  • Pre-compliance testing guidance
Ongoing
Technical Advisor
Monthly retainer for teams that need senior hardware expertise on-demand — architecture guidance, code reviews, and vendor research.
  • Architecture guidance
  • Firmware & hardware review
  • Vendor & component research
  • Team & hiring support
Electronics & PCB Design
Schematic capture, multi-layer PCB layout, digital circuits, microcontroller interfacing, and sensor integration.
Embedded Firmware
Bare-metal C/C++, FreeRTOS, STM32, Arduino. Custom peripheral drivers and communication protocols — CAN, UART, SPI, I2C.
Enclosures & Mechanical
Enclosure design and 3D CAD, FDM 3D printing, benchtop CNC milling and turning. OpenSCAD parametric modeling.
CNC & Motion Control
grblHAL controllers, SmartPendant design, stepper & servo systems, motion planning, real-time control firmware.
Open Source Development
Building and maintaining open source embedded projects. DevCore FreeRTOS framework, thorough documentation, active GitHub community.
Medical Software Background
Professional experience as a software engineer in the medical device industry. Familiarity with quality-oriented development practices.
The Process

How We Work Together

A structured engagement model keeps projects on track and ensures you're never surprised by cost or timeline. Every engagement starts with a free discovery call.

1
Discovery Call
45-minute call to understand your idea, technical requirements, timeline, and budget. No charge, no commitment.
2
Proposal & Scope
Written proposal within 48 hours covering deliverables, timeline, milestones, and a clear fixed-price or T&M quote.
3
Build & Review
Regular design reviews keep you in the loop. Each milestone is signed off before moving to the next phase.
4
Handoff
Complete file package — schematics, PCB files, firmware source, CAD, BOM, and documentation — delivered on final payment.
Open Source

Projects & Portfolio

Every project is open source and documented. These are real problems solved with real hardware — the kind of work that demonstrates what end-to-end embedded development looks like.

Featured Product

SmartPendant

A way to control grblHAL CNC machines — without a PC.

SmartPendant is a standalone handheld controller for grblHAL-based CNC machines. It features a 3.5" touchscreen, precision handwheel, and a full set of probing tools including center finding, edge finding, and automatic tool offset. Designed, developed, and open-sourced by Devtronic — and available fully assembled from our store.
