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.

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.

It’s still hot on both sides of the Atlantic, but Kristina has a new secret weapon for staying cool without making noise. Will Elliot and the others follow suit? Time will tell.

In Hackaday news, well, there’s a lot of it. For starters, Supercon Ten tickets went on sale Thursday morning, but chances are good that by the time you read this, the early bird offering will be all pecked out. But, never fear! More tickets will be released soon enough.

Don’t want to buy a ticket, but still want to go? Submit a talk proposal that gets accepted, and you’ll be welcomed in free of charge. Lucky for you, we just extended the deadline by two weeks to August 26th.

After exhausting the news, Elliot reached into the ol’ Mailbag and found a funny anecdote from [Vik Olliver]. (Funny in that it’ll make you go ‘hmm’.) A brief discussion about imperial vs. metric ensued, but then it was on to the hacks.

This week’s Hackaday podcast is a European affair again, as Elliot Williams is joined by Jenny List on a summer evening to review the week. And we have a feast of hacks for your delectation.

As the title above says, one of the stand-out hacks this week was a set of airless mountain bike tyres 3D printed in glorious fluorescent TPU. They look as though they shouldn’t work but in fact they showed real promise, and we discuss the process behind their design. Then we take a look at a hybrid of a UV printer and an SLA 3D printer, capable of making high-resolution and robust 3D prints. The prospect of new Amigas intrigues us for a while, then carbon-fibre fabric in 3D prints.

Finally we’re in awe of the tech behind the Las Vegas Sphere, and we’re there for some radio at the Danish BornHack hacker camp. Follow that one up and you’ll find a bonus, an unofficial extra Hackaday podcast.

All the usual links are below, but before you head on down to have a listen, don’t forget we’ve got a mailbag for the podcast and we’d love to hear from you!

Elliot Williams and Al Williams got together to compare notes on the most interesting posts this week on the site. As usual, there are just too many choices, so you’ll have to settle for just the few that can fit in a podcast. The guys were excited about 3D printing — both FDM and SLA — as well as a few camera projects. Ever wanted your own starship? They do, too, and you’ll hear about it along with portable radar and more.

Want to make flexible PCBs? Fill up a carbon dioxide tank? Or play Doom via regular expressions? Tune in, and you’ll find out about those stories and more.

Follow along with the links, and as always, tell us what you think about this episode in the comments! Better still, drop us a note in the mailbag, and you might hear your question on a future episode. You can record audio or send us a message, and one of the hosts will read it on your behalf.

On this episode, Hackaday editors Elliot Williams and Tom Nardi discuss their love of electronic paper, clunky cartridges, and keeping old games alive by any means possible. You’ll also hear about getting the most out of the sensors in our 3D printers, playing with X-rays at home, a ring that runs Java, and a roulette wheel that outgrew its 555 timer. Stick around to the end to learn about a different sort of IRC that’s even more niche than the one you’re probably familiar with, as well as the logistical challenges and potential benefits of catching rockets with a giant net.
