What did Hackaday editors Elliot Williams and Al Williams read in Hackaday last week? Probably everything, but you can tune in and hear about their favorites on this week’s podcast. They heard from lots of listeners this week, and also saw DIY projects running from a 3D-printed Stirling engine, to clogs, to LEDs.

There are some over-the-top hacks like a refit for a decades-old watch to do tap-to-pay and a — for lack of a better word — a record player that optically reads MOD files. Want to emulate an iPod? Talk to Eliza? Print a hand-operated rail car? Hackaday is the place to read about it all.

The can’t miss articles included a talk from Hackaday Europe about making magical PCBs and a not-so-brief history of space stations starting in the 1800s.
