What this episode covers

Dave Jones (Mitxela) discusses his portfolio of hardware, firmware, and mechanical projects, including a fluid simulation pendant, a spinning volumetric display, and matrix earrings. He details the engineering challenges of driving dense 0201 LED arrays using Charlieplexing on two-layer PCBs and achieving ultra-low power consumption with the CH32V003 and 8051 microcontrollers. Jones also shares his philosophy on learning metalworking via YouTube, the value of open-source tools like Blender, and the technical depth required to write a Game Boy emulator from scratch.

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

    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.

    41: Pink Universes Die Really Quickly (Repeat)

    Micah Elizabeth Scott, creator of Fadecandy, explains how temporal dithering and frame interpolation overcome the limited dynamic range of WS2812 (Adafruit Neopixel) LEDs to create smooth, high-quality LED art. She details the hardware architecture of the Fadecandy board, which uses an ARM Cortex-M4 to handle these algorithms, allowing artists to focus on creative expression rather than low-level electronics. Scott discusses her transition from a career in embedded systems at Siftio to becoming an 'art engineer,' emphasizing the importance of open-source hardware and building community around accessible technology.

    41: Pink Universes Die Really Quickly

    Micah Elizabeth Scott, creator of Fadecandy, explains how temporal dithering and frame interpolation overcome the limited 8-bit PWM of WS2812 (Adafruit Neopixel) LEDs to achieve high dynamic range and smooth color transitions. She details the open-source hardware and firmware stack, centered on an ARM Cortex-M4, which allows artists to use Processing or Python to drive complex LED sculptures like the 'Triangle' tessellation. Scott discusses her transition from a career at Siftio to focusing on art and community building, using Fadecandy to lower the barrier to entry for LED art. The conversation covers material choices for diffusion, such as HDPE and acrylic, and the importance of creating accessible tools for creative expression.

    350: The State of the Empire Is Good

    Ben Hencke, founder of ElectroMage, discusses the evolution of his Pixelblaze LED controller business from hand-soldered hobbyist projects to a scaled operation using a desktop pick-and-place machine. He details the technical transition from the ESP8266 to the ESP32 microcontroller for the upcoming Pixelblaze V3, highlighting the challenges of multi-core firmware development and race conditions. Hencke also explains his decision to launch V3 via CrowdSupply for its rigorous vetting and fulfillment support, and shares practical advice on solder paste selection and safety.
