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.

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.
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.
Representative Rareworks work across embedded systems, public safety, accessibility, audio, wireless communications, and rapid prototyping.
Designed an end-to-end accessible emergency-alerting demonstration connecting CAP messages, satellite distribution, FM/RDS delivery, and an accessible receiver/tablet interface.
Supported embedded prototypes involving Bluetooth, BLE Mesh, LTE, GPS, vehicle-safety messaging, and field-oriented hardware/software integration.
Applied deep broadcast, audio, DSP, and media-systems experience to commercial and public-service projects requiring reliable real-time operation.
