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.

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.

It's a hot one at both microphones, as Elliot Williams and Kristina Panos wilt in the heat with ice lollies and freezer packs. But still, we persevered long enough to make a podcast.

In Hackaday news, Supercon is on! It's going down in Pasadena, California, but the talks will be somewhere slightly larger, with a courtyard instead of an alley. Get your talk proposals in now! In other Hackaday news, we still have our Frikkin' Lasers Contest going on until Thursday, July 23rd.

Interestingly enough, we got a comment on an older article from none other than [Michael J. Van de Graaff], whose grandfather invented the Van de Graff generator and was "quite upset" when plans for a DIY version appeared in Scientific American. And finally, Google Earth's desktop client is being discontinued, but you can still travel the globe on your phone, or in your PC's browser.

Not only do we have another triple mailbag this week, we have another failed attempt at guessing the Sound by Kristina. However, [Alexander] knew that it was CD-ROM drive a-spinnin'. Speaking of What's That Sound, be sure to let us know your ideas for the new prize.

That sounds like a lot of preamble, but we quickly get to a full slate of hacks, a couple of which are pretty retro in retrospect. Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

This week's podcast sees Elliot joined by Jenny List, as both suffer silently in the European summer heat as the sound of a desk fan would come over on the recording.

The stand-out hack of the week comes from [Bitluni], whose GPU made from thousands of cheap microcontrollers is on a scale we've never seen before. It's an amazing project in itself, but the manufacturing and power consumption issues of so many processors running at the same time make for a discussion of their own.

Otherwise, we have diecasting on the bench, an impressive achievement by any measure, a Raman spectrometer, and an open source take on something like a Kei truck. In quick hacks there's a dicussion of soldering versus crimping for high current connectors, and neon tubes used as digital logic in an organ. The recording finishes with a discussion of 7-segment display history, and whether an engineering education teaches design for manufacture.

Hackadya's Elliot Williams and Al Williams were in a retro mood this week. There was a new '486 computer, a new mechanical TV, and a USB stick with a magnetic personality. Can you watch YouTube on a Game Boy? Maybe.

For the can't miss articles, this week, Elliot and Al reflected on the awkward phase of 3D printers when they transformed from being expensive commercial machines, to where they are now. Meanwhile, Al was interested in how airplanes know how fast they are going. Along the way, there were musical hacks, precision machine tools, and a quantum 8 ball.

In this episode, Hackaday editors Elliot Williams and Tom Nardi start off by taking a trip down the Raspberry Pi memory lane and then tackle a fresh pile of listener mail. The discussion moves on to hacking bike counter, homebrew upgrades to the Nintendo Entertainment System, and building RAM from whats in the parts bin. You'll hear about the latest drop-in upgrade for a classic Casio watch, hosting light bulbs that host subversive literature, and loading Wii U games from a weird disk drive from the 1980s. They'll wrap things up with a dive into the evolving portrayals of brilliant rebels in media, and all the things you can do with a cheap router.

Things are back to normal around the Podcast studio, and this week you'll hear the dulcet tones of Elliot Williams and Kristina Panos.

In Hackaday news, we still have a Frikkin' Lasers Challenge going on, and now you can even enter your project into it! Join the ranks, won't you?

Not only do we have a triple mailbag this week, we have another failed attempt at guessing the sound by Kristina. However, [Baron Maximilian von Knuthausen] knew that it was a train, a British one, even. Then it's on to the hacks, of course, which ought to go far in explaining the show title.

Last week, Elliot got his foot stepped on by a 1.5 metric ton draft horse, and boy is he glad to be back to the relative safety of podcasting! Joining him today is Jenny List, no stranger to farm life, who has been trodden by a cow. It's going to be one of those podcasts, folks.

Another thing the two hosts have in common is a love for the mystery of the numbers station. But did you know that GPS satellites, for the last 20 years, have broadcast literally millions of secret messages to everyone on the earth with a receiver? After that bombshell, we have an ATtiny85 emulating an 8080, a primer on how to embed magnets in 3D prints, definitive proof that more than one cassette mechanism is still being manufactured, and a look at what makes home automation enthusiasts tick.
