My favorite podcasts are super geeky:

• The Hackaday podcast: https://hackaday.com/category/podcasts/
• The Pick, Place podcast: https://www.pickplacepodcast.com/

(They're both available on just about every podcast platform)

Hackaday is catered to a much more general audience than The Pick, Place podcast which is all about the PCB manufacturing/assembly industry. So if you're a geeky sort you'll love Hackaday because just about everything they talk about is super interesting (to geeks) and it's never boring (unlike a lot of other geeky podcasts where the hosts can ramble on for too long about topics that are only mildly interesting).

About the Pick, Place podcast: Never in a million years would did I think I could enjoy such a podcast. They go over the steps and equipment used to make the circuit boards that live inside all the electronics we use every day and it's way more interesting than you'd think! Like, did you know that most professionally-made circuit boards go through the equivalent of a dishwasher? As in, they're washed... With (denatured/deionized) water! Furthermore, these washing machines only need their water changed out like once a month (or sometimes after several months) then they take the little bits of metal it collects over time and they sell them to companies that deal with precious metals (because they'll have multiple pounds of tiny balls of tin, silver, gold, etc).

Oh man I learned so much interesting obscure shit from that podcast! I love it 👍
