Hackaday Podcast 176: Freezing Warm Water, Hacking Lenses, Hearing Data, And Watching YouTube On A PET

It’s podcast time again, and this week Editor-in-Chief Elliot Williams sat down with Staff Writer Dan Maloney to review the best hacks on the planet, and a few from off. We’ll find out how best to capture lightning, debate the merits of freezing water — or ice cream — when it’s warm, and see if we can find out what R2D2 was really talking about with all those bleeps and bloops. Once we decode that, it’ll be time to find out what Tom Nardi was up to while the boss was away with his hidden message in episode 174, and how analog-encoded digital data survives the podcast production and publication chain. But surely you can’t watch a YouTube video on a Commodore PET, can you? As it turns out, that’s not a problem, and neither apparently is 3D printing a new ear.
