Hackaday Podcast 186: Weighing Cats, Slamming VU Meters, Slimmer Skimmers, and Clean Air on the Cheap



Hackaday Editor-in-Chief Elliot Williams took time out from Supercon planning to join Staff Writer Dan Maloney for a look through the hacking week that was. We always try to keep things light, but it’s hard sometimes, especially when we have to talk about wars past and present and the ordnance they leave behind. It’s also not a lot of fun to talk about a continent-wide radio outage thanks to our angry Sun, nor is learning that a wafer-thin card skimmer could be lurking in your ATM machine.
But then again, we did manage to have some fun by weighing cats to make sure they’re properly fed, and making music by pegging VU meters. We also saw how to use PCBs to make a beautiful yet functional circuit sculpture, clean up indoor air on a budget, and move microns with hardware store parts. And we also got to celebrate a ray of international hope by looking back on the year that taught us much of what we know about the Earth.
