Hackaday editors Elliot Williams and Al Williams met up to trade their favorite posts of the week. Tune in and see if your favorites made the list. From crazy intricate automata to surprising problems in Peltier cooler designs, there’s a little bit of everything.
Should bikes have chains? What’s the hardest thing about Star Trek computers to duplicate? Can you make a TV station from a single microcontroller? The podcast this week answers these questions and more. Plus, weigh in on the What’s That Sound contest and you might just score a Hackaday Podcast T-shirt.
For the Can’t Miss segment, Elliot had airships on his mind, while Al’s sick of passwords. But is he sick enough to take electronic pills that transmit his password?
Or download the bit stream and decrypt it by XORing each byte with zero.

Another glitch in the audio, this time just at the end of What’s that Sound. I fixed it pretty fast, though, so only a few of you will hear the extra like five sec of silence that got accidentally included.
Limited edition silence! So relish it.
Let me know if it messes anything up for you. It’s a mystery to me how our podcasting platform handles retractions / fixes, so we’re really interested if it works or doesn’t.
“while Al’s sick of passwords”
Can we start calling him Albert or Allen or some appropriate long form of his name? 😉
I stumbled for a second there, wondering why artificial intelligence was sick of passwords.😄
Let’s just call him A𝜆
Alambda?
Yeah, that’d do it.

Sorry, it’s actually /al oˈilijams/

Ironically, there was a piece making the rounds this week about people using LLMs to pick passwords.
If you know how they work under the hood, with text broken up into tokens and picked by their likelihood, you don’t need to be told what a bad idea that is…
