Hackaday editors Elliot Williams and Mike Szczys chat about our favourite hacks from the past week. We start off with a bit of news of the Bennu asteroid and the new Raspberry Pi Compute Module. We drive ourselves crazy trying to understand how bobbin holders on sewing machines work, all while drooling over the mechanical brilliance of a bobbin-winding build. SCARA is the belt and pulley champion of robot arms and this week’s example cleverly uses redundant bearings for better precision. And we wrap up the show looking in on longform articles about the peppering of microcontrollers found on the Bluepill and wondering what breakthroughs are left to be found for internal combustion.
