3D Model Subscriptions Are Coming, But Who’s Buying?

May 25, 2023 by Tom Nardi 51 Comments

We’ve all been there before — you need some 3D printable design that you figure must be common enough that somebody has already designed it, so you point your browser to Thingiverse or Printables, and in a few minutes you’ve got STL in hand and are ready to slice and print. If the design worked for you, perhaps you’ll go back and post an image of your print and leave a word of thanks to the designer.

Afterwards, you’ll probably never give that person a second thought for the rest of your life. Within a day or two, there’s a good chance you won’t even remember their username. It’s why most of the model sharing sites will present you with a list of your recently downloaded models when you want to upload a picture of your print, otherwise there’s a good chance you wouldn’t be able to find the thing.

Now if you really liked the model, you might go as far as following the designer. But even then, there would likely be some extenuating circumstances. After all, even the most expertly designed widget is still just a widget, and the chances of that person creating another one that you’d also happen to need seems exceedingly slim. Most of the interactions on these model sharing sites are like two ships passing in the night; it so happened that you and the creator had similar enough needs that you could both use the same printable object, but there’s no telling if you’ll ever cross paths with them again.

Which is why the recent announcements, dropped just hours from each other, that both Thangs and Printables would be rolling out paid subscription services seems so odd. Both sites claim that not only is there a demand for a service that would allow users to pay designers monthly for their designs, but that existing services such as Patreon are unable to meet the unique challenges involved.

Both sites say they have the solution, and can help creators turn their passion for 3D design into a regular revenue stream — as long as they get their piece of the action, that is.

AirTags, Tiles, SmartTags And The Dilemmas Of Personal Tracking Devices

May 22, 2023 by Maya Posch 18 Comments

In an ideal world we would never lose our belongings, and not spend a single hour fruitlessly searching for some keys, a piece of luggage, a smartphone or one of the two dozen remote controls which are scattered around the average home these days. Since we do not live in this ideal world, we have had to come up with ways to keep track of our belongings, whether inside or outside our homes, which has led to today’s ubiquitous personal tracking devices.

Today’s popular Bluetooth-based trackers constantly announce their presence to devices set up to listen for them. Within a home, this range is generally enough to find the tracker and associated item using a smartphone, after which using special software the tracker can be made to sound its built-in speaker to ease localizing it by ear. Outside the home, these trackers can use mesh networks formed by smartphones and other devices to ‘phone home’ to paired devices.

This is great when it’s your purse. But this also gives anyone the ability to stick such a tracker device onto a victim’s belongings and track them without their consent, for whatever nefarious purpose. Yet it is this duality between useful and illegal that has people on edge when it comes to these trackers. How can we still use the benefits they offer, without giving stalkers and criminals free reign? A draft proposal by Apple and Google, submitted to the Internet Engineering Task Force (IETF), seeks to address these points but it remains complicated.

Faster Glacier Melting Mechanism Could Cause Huge Sea Level Rises

May 19, 2023 by Lewin Day 115 Comments

When it comes to the issue of climate change, naysayers often contend that we have an incomplete understanding of the Earth’s systems. While humanity is yet to uncover all the secrets of the world, that doesn’t mean we can’t act on what we know. In many cases, as climate scientists delve deeper, they find yet more supporting evidence of the potential turmoil to come.

In the stark landscapes of Greenland, a team of intrepid researchers from the University of California, Irvine, and NASA’s Jet Propulsion Laboratory have unearthed a hidden facet of ice-ocean interaction. Their discovery could potentially flip our understanding of sea level rise on its head.

Revisiting Folk Wisdom For Modern Chronic Wound Care

May 18, 2023 by Lewin Day 81 Comments

In the constant pursuit of innovation, it’s easy to overlook the wisdom of the past. The scientific method and modern research techniques have brought us much innovation, which can often lead us to dismiss traditional cultural beliefs.

However, sometimes, there are still valuable kernels of truth in the folklore of yesteryear. This holds true in a medical study from Finland, which focused on the traditional use of spruce resin to treat chronic wounds, breathing new life into an age-old therapy.

Ask Hackaday: Why Do Self Driving Cars Keep Causing Traffic Jams?

May 8, 2023 by Lewin Day 133 Comments

Despite what some people might tell you, self-driving cars aren’t really on the market yet. Instead, there’s a small handful of startups and big tech companies that are rapidly developing prototypes of this technology. These vehicles are furiously testing in various cities around the world.

In fact, depending on where you live, you might have noticed them out and about. Not least because many of them keep causing traffic jams, much to the frustration of their fellow road users. Let’s dive in and look at what’s going wrong.

Virgin Galactic Cautiously Returns To Flight

May 4, 2023 by Tom Nardi 32 Comments

After Richard Branson delivered some inspiring words from his seat aboard SpaceShipTwo Unity, he unbuckled himself and started to float around the vehicle’s cabin along with three other Virgin Galactic employees. Reaching an apogee of 86 kilometers (53 miles), the passengers enjoyed four minutes of weightlessness during the July 2021 flight that was live-streamed over the Internet to an audience of millions. After years of delays, SpaceShipTwo had finally demonstrated it was capable of taking paying customers to the edge of space. As far as victories go — it was pretty impressive.

Yet despite the spectacle, weeks and months went by without an announcement about when commercial flights of the world’s first “spaceline” would finally begin. Now, nearly two years after Branson’s flight, Unity has flown again. Except instead of carrying the first group of customers, it performed the sort of un-powered test flight that Virgin Galactic hasn’t performed since 2017. Clearly, something didn’t go to plan back then.

The company is being as tight-lipped as ever, saying only that this test flight was necessary to “evaluate the performance of the spaceship…following the modification period.” The exact nature of these modifications is unclear, but for some hints, we could look at the New Yorker article from September 2021. It alleged that, unwilling to derail Branson’s highly publicized flight, Unity’s pilots decided not to abort their ascent despite several warning lights in the cockpit alerting them that the vehicle’s trajectory was deviating from the norm. Virgin Galactic later denied their characterization of the event, but the fact remains that Unity did leave its designated airspace during the flight, and that the Federal Aviation Administration grounded the spacecraft until an investigation into the mishap could be completed.

Barcodes Enter The Matrix In 2027

May 3, 2023 by Kristina Panos 80 Comments

Beep. We’ve come a long way since June 26, 1974 when the first bar code was scanned at a grocery store in Troy, Ohio. That legendary pack of Juicy Fruit proved that even the smallest of items could now carry numbers associated with inventory and price.

By now, we’re all too familiar with this sound as self-checkouts have become the norm. Whereas you yourself could at one time literally check out during the transaction, you must now be on your toes and play find the bar code on every item.

What does the consumer gain from the bar code today? Practically nothing, except the chance to purchase, and potentially return, the item without too much hassle. Well, the non-profit outfit that runs the bar code world — GS1 US — wants to change all that. By 2027, they are confident that all 1D bar codes will be replaced with 2D bar codes similar to QR codes. Why?
