MakerBot And Ultimaker To Merge, Focus On Industry

May 12, 2022 by Tom Nardi 43 Comments

Nine years ago, MakerBot was acquired by Stratasys in a deal worth slightly north of $600 million. At the time it was assumed that MakerBot’s line of relatively affordable desktop 3D printers would help Stratasys expand its reach into the hobbyist market, but in the end, the company all but disappeared from the hacker and maker scene. Not that many around these parts were sad to see them go — by abandoning the open source principles the company had been built on, MakerBot had already fallen out of the community’s favor by the time the buyout went through.

So today’s announcement that MakerBot and Ultimaker have agreed to merge into a new 3D printing company is a bit surprising, if for nothing else because it seemed MakerBot had transitioned into a so-called “zombie brand” some time ago. In a press conference this afternoon it was explained that the new company would actually be spun out of Stratasys, and though the American-Israeli manufacturer would still own a sizable chunk of the as of yet unnamed company, it would operate as its own independent entity.

MakerBot has been courting pro users for years.

In the press conference, MakerBot CEO Nadav Goshen and Ultimaker CEO Jürgen von Hollen explained that the plan was to maintain the company’s respective product lines, but at the same time, expand into what they referred to as an untapped “light industrial” market. By combining the technology and experience of their two companies, the merged entity would be uniquely positioned to deliver the high level of reliability and performance that customers would demand at what they estimated to be a $10,000 to $20,000 USD price point.

When MakerBot announced their new Method 3D printer would cost $6,500 back in 2018, it seemed clear they had their eyes on a different class of clientele. But now that the merged company is going to put their development efforts into machines with five-figure price tags, there’s no denying that the home-gamer market is officially in their rear-view mirror. That said, absolutely zero information was provided about the technology that would actually go into said printers, although given their combined commercial experience, it seems all but a given that these future machines will use some form of fused deposition modeling (FDM).

Now we’d hate to paint with too broad a brush, but we’re going to assume that the average Hackaday reader isn’t in the market for a 3D printer that costs as much as a decent used car. But there’s an excellent chance you’re interested in at least two properties that will fall under the umbrella of this new printing conglomerate: MakerBot’s Thingiverse, and Ultimaker’s Cura slicer. In the press conference it was made clear that everyone involved recognized both projects as vital outreach tools, and that part of the $62.4 million cash investment the new company is set to receive has been set aside specifically for their continued development and improvement.

We won’t beat around the bush — Thingiverse has been an embarrassment for years, even before they leaked the account information of a quarter million users because of their antiquated back-end. A modern 3D model repository run by a company the community doesn’t openly dislike has been on many a hacker’s wish list for some time now, but we’re not against seeing the service get turned around by a sudden influx of cash, either. We’d also be happy to see more funding go Cura’s way as well, so long as it’s not saddled with the kind of aggressive management that’s been giving Audacity users a headache. Here’s hoping the new company, whatever it ends up being called, doesn’t forget about the promises they’re making to the community — because we certainly won’t.

With Rocket Lab’s Daring Midair Catch, Reusable Rockets Go Mainstream

May 12, 2022 by Tom Nardi 34 Comments

We’ve all marveled at the videos of SpaceX rockets returning to their point of origin and landing on their spindly deployable legs, looking for all the world like something pulled from a 1950s science fiction film. On countless occasions founder Elon Musk and president Gwynne Shotwell have extolled the virtues of reusable rockets, such as lower operating cost and the higher reliability that comes with each booster having a flight heritage. At this point, even NASA feels confident enough to fly their missions and astronauts on reused SpaceX hardware.

Even so, SpaceX’s reusability program has remained an outlier, as all other launch providers have stayed the course and continue to offer only expendable booster rockets. Competitors such as United Launch Alliance and Blue Origin have teased varying degrees of reusability for their future vehicles, but to date have nothing to show for it beyond some flashy computer-generated imagery. All the while SpaceX continues to streamline their process, reducing turnaround time and refurbishment costs with each successful reuse of a Falcon 9 booster.

But that changed earlier this month, when a helicopter successfully caught one of Rocket Lab’s Electron boosters in midair as it fell back down to Earth under a parachute. While calling the two companies outright competitors might be a stretch given the relative sizes and capabilities of their boosters, SpaceX finally has a sparing partner when it comes to the science of reusability. The Falcon 9 has already smashed the Space Shuttle’s record turnaround time, but perhaps Rocket Lab will be the first to achieve Elon Musk’s stated goal of re-flying a rocket within 24 hours of its recovery.

Framework Board Gets This Round Display PC Rolling

May 10, 2022 by Tom Nardi 15 Comments

The Framework laptop is already a very exciting prospect for folks like us — a high-end computer that we can actually customize, upgrade, and repair with the manufacturer’s blessing? Sounds like music to our ears. But we’re also very excited about seeing how the community can press the modular components of the Framework into service outside of the laptop itself.

A case in point, this absolutely gorgeous retro-inspired computer built by [Penk Chen]. The Mainboard Terminal combines a Framework motherboard, five inch 1080 x 1080 round LCD display, and OLKB Preonic mechanical keyboard into a slick 3D printed enclosure that’s held together with magnets for easy access. Compared to the Raspberry Pi that we usually find tucked into custom computer builds like this, the Framework board offers incredible performance, not to mention the ability to run x86 operating systems and software.

[Penk] has Ubuntu 22.04 LTS loaded up right now, and he reports that everything works as expected, though there are a few xrandr commands you’ll need to run in order for the system to work properly with the circular display. The standard Ubuntu UI doesn’t look particularly well suited to such an unusual viewport, but we imagine that’s an issue you’ll have to learn to live with when experimenting with such an oddball screen.

It was just a few weeks ago that we brought you word that Framework was releasing the mechanical drawings for their Mainboard module, and we predicted then that it would be a huge boon to those building bespoke computers. Truth be told we expected a cyberdeck build of some sort to be the first one to hit our inbox, but you certainly won’t catch us complaining about seeing more faux-vintage personal terminals.

Altaid 8800 Puts A Front Panel In Your Pocket

May 8, 2022 by Tom Nardi 11 Comments

It’s safe to say that the Altair 8800 is one of the most iconic, and important, computers ever created. The kit-built machine is widely regarded as the first commercially successful personal computer, and as such, intact specimens are bona fide historical artifacts when and if they ever come up on the second-hand market. Accordingly there’s a cottage industry out there dedicated to making affordable replicas, which more often than not, leverage modern hardware to emulate the original hardware.

But that’s not what the Altaid 8800 is. For one thing, it looks nothing like the original Altair. More to the point however, it’s not using modern components to emulate an Intel 8080 computer…it actually is an Intel 8080 computer — complete with fully functional front panel for manually entering in programs. It just happens to be small enough to fit into an Altoids tin, hence the name.

Creator [Lee Hart] didn’t just stop at building a miniature 8080 machine, either. He’s also gone through the trouble of producing a sixteen page faux-vintage magazine to describe the project and its operation. Normally we’d call such a document a “manual”, but somehow in this case that seems to downplay the incredible effort and attention to detail that went into it.

Schematics and firmware are available should you wish to build your own version of the Altaid 8800, but we think the prices for the bare PCBs and complete kits that [Lee] is offering are more than fair for what you get. In fact, if you’ve always wanted to play around with front panel programming and the associated blinkenlights, this might be one of the most affordable options available. Though to be clear, you can also hook the Altaid up to your computer with a USB-to-serial cable if you’re not up to punching in programs on those tiny buttons.

You might think this is one of the most creative and unique retrocomputing projects we’ve ever seen, and you’d be right…if it wasn’t for [Lee]’s own Z80 Membership Card. In some ways the precursor to the Altaid 8800, this diminutive triumph also fits in an Altoids tin and features its own era appropriate magazine-style documentation. We’re detecting something of a theme with these projects…but we certainly aren’t complaining.

Prusa’s Official Enclosure Pulls Out All The Stops

May 8, 2022 by Tom Nardi 50 Comments

It’s well known in the desktop 3D printing world that you get what you pay for. If you want to spend under $300 USD, you get a Creality Ender 3 and deal with its slightly half-baked nature. Or if you’ve got the money to burn, you buy a Prusa i3 MK3 and know that you’ll remain on the cutting edge thanks to a constantly evolving slicer and regular hardware revisions.

Now it stands to reason that an expensive product will have expensive accessories, but even still, the recently unveiled “Original Prusa Enclosure” is sure to induce a bit of sticker shock in even the most ardent of [Josef Průša]’s fans — the most bare-bones configuration of the 10 kg (22 lbs) box rings up at $349 USD. You read that right, just the enclosure for Prusa’s flagship machine costs more than the average Chinese 3D printer. In fact it costs as much as the kit version of the Prusa Mini, which incidentally, is set to get its own version of the enclosure sometime in the future. If you select all the bells and whistles, a fully-decked out Prusa Enclosure will cost you $700 USD, plus shipping.

Creating An Image Format For Embedded Hardware

May 8, 2022 by Tom Nardi 60 Comments

Whether its one of those ubiquitous little OLED displays or a proper LCD panel, once you’ve got something a bit more capable than the classic 16×2 character LCD wired up to your microcontroller, there’s an excellent chance you’ll want to start displaying some proper images. Generally speaking that means you’ll be working with bitmap files, but as you might expect when pushing a decades-old file format into an application it was never intended for, things can get a little messy. Which is why [gfcwfzkm] has created the Portable Image File (PIF) format.

This low-overhead image format is designed specifically for microcontrollers, and can be decoded on devices with at least 60 bytes of free RAM. Images stored with PIF not only require fewer computational resources to process, but equally important, take up less space on flash. The format supports both color and monochrome images, and the GitHub repo even includes a graphical Python 3.10 tool that lets you convert your images to either .pif files or a .h header file for embedding directly into your C code.

[gfcwfzkm] has provided some source code to show you how to get the PIF library up and running, but as of the time of this writing, there isn’t any example code for using PIF within the Arduino environment. That’s no big deal for the old hands in the audience, but we’re interested in seeing how the community can make use of this file format once it’s available in a bit more beginner-friendly package. It’s one of the final unchecked items on the todo list though, so it shouldn’t be long now.

Of course nothing is wrong with using bitmaps to display images in your microcontroller projects, and there’s a certain advantage to fiddling around with the well-known image format. But if a new file type is all it takes to speed up access times and cram a few more images onto the chip, we’re definitely ready to upgrade.

Bee Motion Combines ESP32 With PIR Sensor And USB-C

May 7, 2022 by Tom Nardi 3 Comments

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a project that could benefit from the pairing of a powerful WiFi-enabled microcontroller and a passive infrared (PIR) motion sensor, the Bee Motion created by [Paul Price] is certainly worth a close look.

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects. In addition to the expected onboard voltage regulation, there’s also a LiPo charge controller and status LEDs for mobile or battery-backed operation.

While there’s far too many variables involved for [Paul] to give a specific runtime for the Bee Motion, he’s run some numbers and found that a 1500 mAH cell could potentially keep the board running for over a year if you’re taking advantage of the MCU’s deep sleep capabilities. When it’s time to recharge, whenever that may be, the board’s USB-C connector means you won’t be searching around for the proper cable.

Schematics and CAD files are available in the Bee Motion GitHub repo, and [Paul] is also selling assembled boards on Tindie. All you need now is to get inspired by some of the slick PIR projects we’ve covered in the past.
