Ep 377: Parallel Pixels, Wiggly Consoles, and Seven Segments

Hackaday Podcast · 10 Jul 2026 · 1h 11m · Episode 377

What this episode covers

Jenny List and Elliot Williams discuss [Bitluni]'s massive GPU project, which uses 8,192 CH570 microcontrollers to drive RGB LEDs, highlighting the extreme power consumption (2 kW) and manufacturing hurdles like PCB panelization limits and programming logistics. They also cover a home-made die casting machine using graphite molds, a DIY Raman spectrometer built with 3D printed parts, and an open-source Kei truck design by Andy Diderossi. The episode concludes with a deep dive into the history of 7-segment displays and a critique of engineering education regarding design for manufacturing, based on List's article.
