Ep 155: Dual Integrating Spheres, More Magnetic Switches, PlottyBot, Red Hair in Your Wafers

Hackaday Podcast · 11 Feb 2022 · 1h 03m · Episode 155

What this episode covers

Hackaday editors Elliot Williams and Tom Nardi discuss a variety of hardware projects, including a 3D-printed model of the James Webb Space Telescope's mirror actuators by Zachary Tong, which features flexures for fine and coarse adjustment. They also cover PlottyBot, a refined drawbot by Ben that uses a Raspberry Pi and Python for handwriting capture, and two different approaches to magnetic keyboard switches: Riskables' void switch and Famicu's resin-printed design. The episode concludes with a discussion on DIY integrating spheres using barium sulfate for laser calibration and flashlight testing, and a story about an operator's beard hair causing wafer prober failures.

    83: The First Time I Was Electrocuted

    Mark Johnson, the anonymous creator of the open-source Raman Pi spectrometer, discusses building a low-cost Raman spectroscopy device using a Raspberry Pi, 3D printed parts, and off-the-shelf components. He details the technical challenges of aligning optics, selecting a linear CCD over the Raspberry Pi camera module, and managing the intense documentation and video production required for the Hackaday Prize. Johnson also shares his background in electronics surplus and his fascination with high-voltage hobbyist projects like fusors.
