Embedded Rust Workshop: Reflections from Hackaday Supercon
Every November, hundreds of engineers, makers, and hardware hackers converge in Pasadena, California for Hackaday’s annual Supercon, a three-day celebration of open hardware, creative problem-solving, tinkering, and passion projects. It’s part conference, part reunion, and part art exhibit. Supercon has always been about sharing knowledge, so this year I decided to contribute something new: an…
