The OSTRWERK Initiative
Introduces the OSTRWERK open-source hardware initiative providing accessible RF tooling and equipment for amateur radio operators.
Summary
In this practical hardware presentation from the DEF CON Safe Mode Ham Radio Village, a radio amateur introduces the OSTRWERK Initiative, designing rugged, field-deployable radio communication kits for disaster response. Opening at 00:04, the speaker reviews the technical requirements for portable communication stations capable of operating during extended power grid failures.
At 11:01, the presenter examines field station architectures, demonstrating custom Pelican-style waterproof cases integrating VHF/UHF transceivers, lithium iron phosphate battery management systems, and antenna tuners.
At 22:04 and 33:02, the speaker conducts a hardware demonstration, evaluating audio interface wiring between transceivers and Raspberry Pi single-board computers while discussing enclosure thermal management and magnetic keyboard mounting for portable digital emergency operations.
