Open Hardware Manager

Building the coordination systems that activate distributed manufacturing when centralized supply chains fail.

The Problem

COVID-19 revealed a critical gap in manufacturing infrastructure.

When centralized supply chains collapsed, 1,800+ maker organizations worldwide produced 48 million medical supply units - proving distributed capacity exists everywhere. Makerspaces, fab labs, small manufacturers stood ready to help.

But 70% of volunteer effort went to manual coordination rather than production:

• Matching designs to facility capabilities
• Validating technical specifications
• Routing materials across networks
• Aggregating output from hundreds of small producers
• Quality assurance and standards compliance

The capacity existed. The coordination infrastructure didn't.

The next pandemic, natural disaster, or supply chain disruption will find us just as unprepared - unless we build the infrastructure now, before the crisis.

The Solution

Universal data standards + automated coordination = activatable resilience

Over three years, I co-developed machine-readable standards for open hardware (OpenKnowHow for designs, OpenKnowWhere for facilities) with the Open Source Hardware Association, Field Ready, and the University of Bath. But standards alone don't solve anything - nobody will manually implement a data standard.

The Open Hardware Manager is the reference implementation that makes these standards actually useful.

Core Capabilities

Automated Matching
Multi-layered algorithm (exact → heuristic → NLP → AI/ML) that matches hardware requirements with facility capabilities. Given a design, find every capable manufacturer within X distance.

Manifest Generation
4-layer progressive enhancement system converts unstructured project data (GitHub repos, documentation) into machine-readable OKH manifests automatically.

Supply Tree Construction
Maps complete manufacturing solutions: multi-stage dependencies, material sourcing, quality validation, time constraints, resource allocation across networks.

Package Management
Build, verify, and distribute complete hardware packages with all dependencies, documentation, and validation data.

Domain-Aware Validation
Quality levels (hobby, professional, medical) with standards compliance checking (ISO 9001, ISO 13485, etc.)

Multiple Access Methods
Web UI at openhardwaremanager.org, REST API, CLI tool (ohm command), Python library - 27 services across 7 command groups

Technical Architecture

Component-Based Design:

• generation: Unstructured input → normalized OKH/OKW formats
• analysis: Extract requirements and capabilities
• matching: Connect requirements to facilities at scale
• packaging: Build and distribute complete projects

Tech Stack: Python | FastAPI | Pydantic | LangChain | Docker | Azure Blob Storage

Current Status & Impact

Published, Live, and Seeking Adoption

The system is complete and functional. Standards are published. OHM v0.9.0 is live at openhardwaremanager.org - browse designs, run a match, and open the resulting supply tree in the browser, no Docker or CLI required. The image is also available on Docker Hub (touchthesun/openhardwaremanager) with multi-architecture images (linux/amd64 and linux/arm64). A new partnership with Maps of Making now brings their network of facilities directly into the matching engine as candidates alongside your own facility data, widening the pool of capacity OHM can search against. Now focused on adoption through conference presentations, documentation, and community building.

Why This Matters:

Infrastructure work is unglamorous, unfunded, and necessary. Supply chain resilience isn't profitable until it's too late. I'm building it anyway because the alternative is preventable deaths during the next crisis.

Collaboration:

• Internet of Production Alliance (IoPA) - international coordination
• Open Source Hardware Association (OSHWA) - standards development
• Field Ready - humanitarian deployment expertise
• University of Bath - research partnership
• EU mAkE Project - African/European makerspace infrastructure
• Maps of Making - facility network integration, live in v0.9.0

Emerging Partnerships: Early-stage conversations are underway with DMDM (Distributed Medical Device Manufacturing - FDA-registered, producing tourniquets for Sudan and Gaza) and GOSQAS (Global Open Source Quality Assurance System, part of Public Invention - open-source closed-loop tracking for humanitarian supply chains). Both are exactly the kind of distributed, humanitarian-facing manufacturing this project exists to support.

The Vision

Supply Chain Mesh Networks

The goal isn't replacing centralized manufacturing - it's creating resilient alternatives that activate when centralized systems fail.

During the next pandemic, natural disaster, or geopolitical disruption:

• Designs publish in machine-readable OKH format
• Facilities advertise capabilities in OKW format
• Matching engines route production to available capacity
• Supply trees coordinate multi-stage manufacturing
• Networks self-organize without manual coordination

The infrastructure exists now. The coordination layer is being built. The next crisis will test whether we learned from the last one.
