Ep 342: Poopless Prints, Radio in Your Fillings, and One Hyperspectral Pixel at a Time

Hackaday Podcast · 17 Oct 2025 · 1h 12m · Episode 342

What this episode covers

Hosts Elliot Williams and Dan Maloney review the week's Hackaday news, starting with the Supercon keynote panel featuring Star Trek designers Michael and Denise Okuda, Rick Sternbach, and others. They discuss Jan Gritz's 'poopless' 4-color co-extruding 3D printer hotend, which uses laminar flow to print multi-colored objects without purging, and infrauctuity's hyperspectral camera that rasterizes a USB spectrometer across a 400x400 frame to capture spectral data. The hosts also cover Ringway's debunking of the 'radio in fillings' myth, Soy Boy Soft's air-powered squishy robot using pneumatic logic gates, and Project 326's use of Americium-241 for x-ray imaging of electronics.
