Hackaday Podcast 182: Sparkpunk Photography, Anti-Xiomi Air Filters, And Keyfob Foibles

Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi are here to bring you the best stories and hacks from the previous week (and maybe a little older). Things kick off with news that the Early Bird tickets for the 2022 Hackaday Supercon tickets sold out in only two hours — a good sign that the community is just as excited as we are about the November event. But don’t worry, regular admission tickets are now available for those who couldn’t grab one out of the first batch.

This week there’s plenty of vehicular hacks to talk about, from John Deere tractors running DOOM to a particularly troublesome vulnerability found in many key fobs. We’ll also lament about the state of 3D CAD file formats, marvel at some retro-futuristic photography equipment, and look at the latest in home PCB production techniques. Wrapping things up there’s a whole lot of cyberdeck talk, and a trip down silicon memory lane courtesy of Al Williams.

    1. _You_ can drill the holes, but the process can’t. (Contrast with PCB milling.)

      Worse, _you_ must drill the holes. I hate drilling the holes.

      Should really automate it, but it’s a simple matter of software and setup. Path of least resistance is just to design in all SMT.

  1. To be fair tape measure antennas are usually not used for transmitting but instead used for radio direction finding. They might not be great at radiating but they’re good enough at receiving that they’re good for tracking down a signal

  2. Has Xiaomi gone full DRM with newer models? Earlier air purifier models recognized official filters with RFID stickers, but they were just used to provide a tiny bit of convenience. When the purifier detects a new filter, the filter life counter gets reset automatically, which can also be done manually by pressing a button.
    Even if the user doesn’t do it, the purifier keeps the running, there are just annoying reminders that appears on the OLED display from time to time.
