Ep 240: An Amazing 3D Printer, A Look Inside Raspberry Pi 5, and Cameras, Both Film and Digital
Elliot Williams and Dan Maloney review a week of hardware hacks, highlighting a custom Raspberry Pi RP1 peripheral chip that offloads Southbridge functions to an older 40nm process, and a novel cable-driven 'Marionette' 3D printer by Deedza Cat that uses strings and winches for motion. They also discuss a film-to-digital SLR adapter by I'm Back Film, an automated home hydrogen generator by Hyperspace Pirate, and a deep dive into microphone tonal characteristics by Jim Lila. The episode covers the engineering trade-offs of these projects, from the RP1's development costs to the mechanical complexities of cable tensioning.
