## Summary

Michael Ossmann, founder and CTO of Great Scott Gadgets, discusses the creation of open-source hardware tools like HackRF One and Ubertooth One, which emerged from his background in wireless security research. He explains how his work on public safety protocols like APCO P25 and the NSA's ANT catalog led to the development of accessible RF tools and a passion for education through his SDR video series. Ossmann also shares anecdotes about unexpected uses of his hardware, such as studying shark behavior, and the importance of open-source software like GNU Radio Companion in lowering the barrier to entry for digital signal processing.
