Ep 129: Super Clever 3D Printing, Jigs and Registration Things, 90s Car Audio, and Smooth LED Fades

Hackaday editors Mike Szczys and Elliot Williams have found a critical mass of projects this week that wouldn't be possible without 3D printers. There's an absolutely astounding model roller coaster that is true to the mechanisms and physics of the original (and beholden to hours of sanding and painting). Adding sheet material to the printing process is a novel way to build durable hinges and foldable mechanisms. Elliot picks out not one, but two quadruped robot projects that leverage 3D-printed parts in interesting ways. And for the electronics geeks there's a server rack stuffed with Raspberry Pi, and analog electronic wizardry to improve the resolution of the WS2811 LED controller. We wrap it all up with discussions of flying boats, and adding Bluetooth audio to old car head units.
