Hackaday Podcast Episode 273: A Tube Snoot, Dynamic Button Blobs, And Tokamaks Aren’t Whack

May 31, 2024 by Kristina Panos 8 Comments

This week, it was Kristina’s turn in the hot seat with Editor-in-Chief Elliot Williams. First up in the news: Germany’s solar and wind power generation have resulted in excess energy, which some people think is bad. In Hackaday news, the entries in the 2024 Business Card Challenge are really stacking up.

Then it’s on to What’s That Sound, which Kristina provided this week and managed to stump Elliot. Can you get it? Can you figure it out? Can you guess what’s making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt.

Then it’s on to the hacks, beginning with an improved spectrometer that wasn’t easy, and a rotary phone kitchen timer that kind of was. We’ll talk about badges turned invitations, reinventing rotary switches, and dynamic button blobs. Finally, we get the lowdown on the state of nuclear fusion, and posit why chatting online isn’t what it used to be.

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!

Download and savor at your leisure.

How Facebook Killed Online Chat

May 29, 2024 by Lewin Day 84 Comments

In the early days of the internet, online conversations were an event. The technology was novel, and it was suddenly possible to socialize with a whole bunch of friends at a distance, all at once. No more calling your friends one by one, you could talk to them all at the same time!

Many of us would spend hours on IRC, or pull all-nighters bantering on MSN Messenger or AIM. But then, something happened, and many of us found ourselves having shorter conversations online, if we were having any at all. Thinking back to my younger days, and comparing them with today, I think I’ve figured out what it is that’s changed.

The Tragic Story Of The Ill-Fated Supergun

May 28, 2024 by Lewin Day 63 Comments

In the annals of ambitious engineering projects, few have captured the imagination and courted controversy quite like Gerald Bull’s Supergun. Bull, a Canadian artillery expert, envisioned a gun that could shoot payloads directly into orbit. In time, his ambition led him down a path that ended in both tragedy and unfinished business.

Depending on who you talk to, the Supergun was either a new and innovative space technology, or a weapon of war so dangerous, it couldn’t be allowed to exist. Ultimately, the powers that be intervened to ensure we would never find out either way.

Camera And Lens Repair Hack Chat

May 27, 2024 by Dan Maloney 13 Comments

Join us on Wednesday, May 29 at noon Pacific for the Camera and Lens Repair Hack Chat with Anthony Kouttron!

Unlike the normies, most of us are pretty comfortable looking under the hood of just about anything electronic or mechanical. Whether it’s to effect a repair, make a modification, or just to take a look around, voiding warranties is what we do. A lot of us have hard limits, though, and will shy away from certain types of equipment. High voltages and radiation come to mind, as well as machines with lots of spinny bits that can devour your hands in a trice. One mustn’t be foolhardy, after all.

But one place that we’ve always feared to tread for some reason is camera equipment. Perhaps it has to do with all those impossibly tiny screws with subtly different lengths and the knowledge that putting the wrong screw in the wrong hole could have disastrous results. Or maybe it’s just the general fear that messing around with the insides of lenses could knock something slightly off-kilter and ruin the optics.

We’re certainly glad that Anthony Kouttron doesn’t share this trepidation. We recently featured a lens repair that he accomplished that was packed with tips and tricks for optical repairs. It turns out that Anthony has been repairing cameras for leisure since 2010, and has serviced both consumer and high-end cinema equipment — so he’s seen his fair share of broken camera bits. We’ve asked him to drop by the Hack Chat, so if you’ve been hesitant to dive into optical fixes, now might be your chance to learn about the dos and don’ts of camera and lens repair.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 29 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

ICQ Will Shut Down On June 26 This Year

May 26, 2024 by Maya Posch 29 Comments

In many ways, ICQ has always been a bit of a curiosity. It was one of the first major instant messenger clients of the 1990s. It saw broad uptake alongside the likes of AOL Instant Messenger and MSN Messenger. Yet, it outlasted both of them despite not being attached to an industrial juggernaut like AOL or Microsoft. After 27 years, however, it seems that the last petal will drop, with the shutdown of ICQ announced on the ICQ website for June 26, 2024.

Originally launched by an Israeli company, Mirabilis, in June of 1996, it took the Internet by storm, leading to AOL buying Mirabilis in June of 1998. Under the wing of AOL, ICQ kept growing its user base until it was sold to Digital Sky Technologies (now VK, which operates Mail.ru) in 2010. Around this time, the likes of Facebook and Google, with their own messaging solutions, came onto the scene, leaving ICQ to flounder. Ultimately, ICQ found a new home in the Russian market as a mobile messaging system until its imminent shutdown. Users are urged to move to the VK Messenger instead.

The demise of ICQ obviously led to a blast of nostalgia on sites like Hacker News, even though it has lost relevance in the West for many years. We’re sad to see this chapter end and will mourn the demise of our UINs (RIP, 61007952) along with our fellow compatriots in the usual IRC channels.

This is what happens when you depend on the grid. Going off the grid doesn’t have to look homemade, either.

You’ve Probably Never Considered Taking An Airship To Orbit

May 13, 2024 by Lewin Day 75 Comments

There have been all kinds of wild ideas to get spacecraft into orbit. Everything from firing huge cannons to spinning craft at rapid speed has been posited, explored, or in some cases, even tested to some degree. And yet, good ol’ flaming rockets continue to dominate all, because they actually get the job done.

Rockets, fuel, and all their supporting infrastructure remain expensive, so the search for an alternative goes on. One daring idea involves using airships to loft payloads into orbit. What if you could simply float up into space?
