## Summary

Jeff Keyzer of MightyOhm.com and Michael Ossmann of Great Scott Gadgets join host Chris Gaddis at ToorCamp to discuss their current projects and philosophies on learning electronics. Keyzer details his work supplying Geiger counter kits and his non-electronic hobby of restoring a 1962 Sunbeam Alpine, while Ossmann describes his team's large-scale creme brulee project and the design of a 'Jar of Fireflies' badge to reduce waste. The conversation explores teaching strategies, contrasting the 'start with a working system' approach of Arduino with the reverse-engineering mindset of software hackers, and highlights the upcoming release of the GreatFET hacking tool.
