Embedded Systems, Wireless Communications, Audio Technology & Public Safety Solutions

Rareworks LLC designs and prototypes connected hardware and software systems for organizations with unusual technical challenges. Founded in Washington, DC in 2014 by Rich Rarey, Rareworks brings together embedded firmware, wireless communications, audio engineering, public-safety technology, accessibility systems, and rapid hardware/software prototyping.

Rareworks engagements have included BLE and LTE-connected mobility systems, Raspberry Pi-based embedded prototypes, accessible emergency-alerting infrastructure, aviation and sUAS research support, audio and media systems, and facility vulnerability studies. We help clients turn a technical idea into something that can be tested, demonstrated, and improved in the real world.

Embedded hardware prototype and electronics

Hardware

Rareworks supports rapid embedded prototyping using Raspberry Pi, custom plug-in boards, and traditional microcontroller platforms when the application calls for lower power, tighter timing, or production-ready hardware.

We help clients evaluate architecture, connect sensors and interfaces, build proof-of-concept hardware, write supporting firmware and Linux software, and move from demonstration toward a more durable embedded design.

Systems engineering and integration work

Systems

Rareworks integrates hardware, firmware, networking, media, and application layers into complete working systems. Projects have included accessible emergency-alerting demonstrations, connected mobility and vehicle-safety prototypes, audio and broadcast infrastructure, and sUAS research support.

Our systems work emphasizes practical field use: clear requirements, defensible tradeoffs, prototype testing, documentation, and integration with the client's existing hardware, software, and operational constraints.
