## Summary

Piotr Esden-Tempski, founder of One Bit Squared, discusses the development of open-source hardware and software tools for embedded systems, specifically the Blackmagic Probe and OneBitC board. He explains the technical rationale behind creating these tools, citing licensing issues with STMicroelectronics libraries and the need for robust, open debugging capabilities like GDB integration. The conversation covers the hardware design of the Lisa series autopilots, the software architecture of Paparazzi UAV, and the community-driven growth of the Blackmagic Probe project following a successful Kickstarter.
