Hackaday editors Mike and Elliot Williams catch up on a week’s worth of hacks. It turns out there are several strange radio bands that don’t require a license, and we discuss this weekend’s broadcast where you can listen in. It’s unlikely you’ve ever seen the website check-box abused quite like this: it’s the display for playing Doom! Just when you thought you’d seen all the ESP32’s tricks it gets turned into a clock styled after Out Run. Mike geeks out over how pianos work, we’re both excited to have Jeremy Fielding giving a Keynote talk at Remoticon, and we wrap things up with a chat about traffic rules in space.

Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!
