An Open Hardware Laser Engraver For Everyone

Published

on


Right now, you can get a diode laser engraver on eBay for around $100 USD. That sounds like a deal, but it’ll probably use some arcane proprietary software, won’t be terribly accurate, and the laser itself will almost certainly be fully exposed. Of course there’s no shortage of DIY builds which improve upon this situation greatly, but unfortunately the documentation and instructions to replicate them yourself often leave a lot to be desired.

To get a safe and accurate laser platform into the hands of hackers everywhere, we need more well documented open source designs that are actually built with community in mind. Projects like the Engravinator from [Adam Haile]. This isn’t a one-off design with documentation thrown together after the fact, it’s a fully open hardware engraver with a concise assembly guide that’s built from 3D printed parts and readily available components. You’re free to source and print the parts yourself or, eventually, purchase everything as a kit.

Pen-equipped Engravinator

The microwave-sized Engravinator is built from standard 2020 aluminum extrusion, and offers a workable area of 130mm x 130mm. There’s a hatch on the front of the enclosure for objects that are small enough to fit inside the machine, but the open bottom and handles on the top also allow the user to place the Engravinator directly onto the work surface. [Adam] says this feature can be especially useful if you’re looking to burn a design into a tabletop or other large object.

Outside of the aluminum extrusion and miscellaneous hardware that make up the frame, most of the other parts are 3D printed. Released under the CERN Open Hardware License v1.2 and distributed as both STL and STEP files, the printable parts for the Engravinator are ripe for modification should you be so inclined. The same goes for the DXF files for the enclosure panels, which will need to be cut out of orange acrylic with a CNC or (ironically) a laser.

Movement is provided by two NEMA 17 steppers and a GT2 belt arrangement, and [Adam] has even put together a custom control board he calls the Platypus using TMC2100 drivers; though you could always swap that out for a basic RAMPS board if you’re going down the DIY route. You can use any PWM-controlled diode laser with the common 16x40mm M3 bolt pattern, of which there’s no shortage of options on eBay.

[Adam] estimates the total cost of an Engravinator, assuming you start from absolutely nothing, is between $300 and $400 USD. But naturally that price will vary significantly on how much of the hardware you can find by rummaging through your parts bins or even by salvaging from something else. If you’ve got an outdated 3D printer collecting dust, you could pull a good deal of the hardware required from there.


We had a chance to see the Engravinator in action at the recent 2019 East Coast RepRap Festival, and definitely came away impressed. It’s a solid machine and the results on display all looked incredibly crisp. Our favorite feature (which appears to be optional) was the small camera mounted at the top of the enclosure that allowed the user to superimpose the image to be burned over the view of the workpiece to check alignment before burning.

Some will likely argue that the all-up cost of the Engravinator is still a bit too high for wide adoption, especially considering you can get a K40 for around the same price. But if you’d rather stick with a diode laser and don’t feel like taking your chances with the questionable hardware currently on the market, we think this is a project to keep an eye on.

Apple’s AR glasses just hit a key developmental milestone

Published

on



  • Apple’s rumored AR glasses recently hit a key developmental milestone
  • Apple’s AR glasses may arrive as soon as 2022.
  • Tim Cook has long been a fan of Augmented Reality and believes the technology’s impact could rival that of the iPhone.

Amid rumors that Apple may release a pair of Augmented Reality-powered glasses in early 2022, a new report from The Information relays that work on the highly anticipated product continues to move forward. The report specifically claims that a key developmental milestone was recently reached as semitransparent lenses for the device recently “passed the prototype stage and entered trial production.”

The report indicates that mass production is still a good two years away, which aligns with previous reports we’ve seen. Of course, there’s no guarantee Apple’s AR glasses will hit the market given that the entire project has been subject to various delays in recent years. There was even a brief period of time, rumor has it, where Apple canceled the project altogether.

That notwithstanding, The Information adds:

The lenses use a polarized system, similar to the technology in 3D movie glasses, which create the illusion of depth using stereoscopic images, the person said. The technology is similar to that in other AR and VR devices already on the market from Microsoft, Magic Leap and Facebook…

The person said making the AR lenses is especially challenging because they are composed of multiple, extremely thin layers of different synthetic materials, each of which is susceptible to bubbles, scratches and other marks. To reduce defects, the lenses must be manufactured in dust-free zones known as clean rooms.

Apple reportedly has upwards of 1,000 employees currently working the project. You might also recall that code in an iOS 13 build from last September contained references to AR-based applications and devices.

As to what type of functionality Apple’s AR glasses will bring to the table, the device will include a microphone to allow users to call Siri into action and, of course, field and make calls. There are also indications that the device will ship with a built-in accelerometer so that the device can register commands when a user moves his or her head in a particular direction.

The first incarnation of Apple AR glasses will likely not include a camera due to battery life and design considerations. Subsequent models, however, may feature a camera module.

Design-wise, it’s believed that Apple’s AR glasses will support both polarized and prescription lenses. Further, different sizes will be available for both men and women. Aesthetically, rumor has it that the product will look like a regular pair of glasses with thicker than average frames which will contain the battery and assortment of chips.

It’s far too soon to know how much Apple’s AR glasses might cost, but an alleged Foxconn insider a few years ago suggested it might be in the range of $600.

Incidentally, Tim Cook has long been a champion of Augmented Reality, with the Apple CEO a few years ago stating that it remains a “core technology” Apple continues to invest in.

“I think AR is extremely interesting and sort of a core technology,” Cook said back in 2016. ” So, yes, it’s something we’re doing a lot of things on behind that curtain that we talked about.”

All told, it will be interesting to see how the market reacts to Apple’s AR Glasses if and when it’s released. Recall that Google Glass, while intriguing, was more of a gimmick with few real-world applications. In turn, Google Glass didn’t gain any traction in the market. If Apple’s AR glasses, in contrast, can prove itself to be more than a gimmick, perhaps Apple will have another breakout hit on its hands.

Microsoft is adding a virtual auditorium view to its Teams communication platform in a bid to make video meetings feel more natural during lockdown.

The firm has developed AI technology that places participants alongside one another, digitally seated with the same background, creating the impression everyone is in the same room.

‘Together mode’ is designed to help people feel more connected and less fatigued by video meetings, which have become commonplace among those working from home since coronavirus lockdown measures came into place in March.

The feature – which rolls out on Thursday before becoming generally available in August – is one of a number of improvements the tech giant is introducing on Microsoft Teams.

Users can expect to find video filter enhancements and emoji-based live reactions to pop up on screen among the raft of updates.

Microsoft Teams displays, a new category of device for the firm, has also been announced amid a surge in demand for video communication tools and growing competition from the likes of Zoom, Facebook and Google.

These Teams-focused devices will have an ambient touchscreen and a hands-free experience powered by Cortana.
