As the calendar turns a leaf into September, Elliot Williams is joined by Jenny List for our weekly look at all things Hackaday.
In the news, our retrocomputing competition is well under way, but there’s plenty of time to get an entry in if you’ve got a cool old-style project to show us. And then Elliot’s been chasing seismic surveyors in Munich, where they’re looking for geothermal energy.
In the stand-out hacks there’s a discussion of smoothing 3D prints using frickin’ lasers, the effect of unreasonably high RAM and storage prices on the single board computer ecosystem, and an unfortunate air conditioning system that’s tricked into believing it’s a hot day. Finally, we look in depth at PETG, and take a dive into reverse Polish notation.

Mailbag:
In out mailbag this week we had [Kevin Opalka] asking about roadtrip hacks and [Matthew Rowberry] explaining that most versatile yet underrated prototyping medium: the humble Lego brick. Which in turn gives us the chance to mention Lego House: Right Next To Denmark’s Legoland, But Way Cooler, a trip we made back in 2019.
