Hackaday editor Elliot Williams and contributor Jonathan Bennett discuss the past week of Hackaday. Freeman Dyson, who wanted to send us to space on the back of nuclear explosions, passed away. Only slightly less dangerous, we looked at self-balancing vehicles, 3D printed press brakes, and making rubies in the home lab. All the usual suspects make cameo appearances: robots, FPGAs, and open-source software. Show notes: https://hackaday.com/?p=402113
