## Summary

Travis Goodspeed, an independent hardware hacker and creator of the GoodFet and GoodWatch, discusses his history of open-source projects and the communities they spawn. He details the technical challenges of the GoodWatch, including using the TI CC430 chip for low-power paging and overcoming hardware bugs in the real-time clock. Goodspeed also explains how he reverse-engineered the MD380 radio firmware to add promiscuous mode and how the GoodFet evolved into the GreatFET for USB emulation and security testing.
