Handheld 3D Scanning, Using Raspberry Pi 4 and Intel RealSense Camera

Image
Raspberry Pi 4 (with USB 3.0) and Intel RealSense D415 depth sensing camera. When the Raspberry Pi 4 came out, [Frank Zhao] saw the potential to make a realtime 3D scanner that was completely handheld and self-contained . The device has an Intel RealSense D415 depth-sensing camera as the main sensor, which uses two IR cameras and an RGB camera along with the Raspberry Pi 4. The Pi uses a piece of software called RTAB-Map — intended for robotic applications — to take care of using the data from the camera to map the environment in 3D and localize itself within that 3D space. Everything gets recorded in realtime. This handheld device can act as a 3D scanner because the data gathered by RTAB-Map consists of a point cloud of an area as well as depth information. When combined with the origin of the sensing unit (i.e. the location of the camera within that area) it can export a point cloud into a mesh and even apply a texture derived from the camera footage. An example is shown below t

Shoot the Moon with this Homebrew Hardline RF Divider

Image
You can say one thing for [Derek]’s amateur radio ambitions — he certainly jumps in with both feet. While most hams never even attempt to “shoot the Moon”, he’s building out an Earth-Moon-Earth, or EME, setup which requires this little beauty: a homebrew quarter-wave hardline RF divider , and he’s sharing the build with us. For background, EME is a propagation technique using our natural satellite as a passive communications satellite. Powerful, directional signals can bounce off the Moon and back down to Earth, potentially putting your signal in range of anyone who has a view of the Moon at that moment. The loss over the approximately 770,000-km path length is substantial, enough so that receiving stations generally use arrays of high-gain Yagi antennas . That’s where [Derek]’s hardline build comes in. The divider acts as an impedance transformer and matches two 50-ohm antennas in parallel with the 50-ohm load expected by the transceiver. He built his from extruded aluminum tubing a

Behind The Scenes Of Folding@Home: How Do You Fight a Virus with Distributed Computing?

A great big Thank You to everyone who answered the call to participate in Folding@Home, helping to understand proteins interactions of SARS-CoV-2 virus that causes COVID-19. Some members of the FAH research team hosted an AMA (Ask Me Anything) session on Reddit to provide us with behind-the-scenes details. Unsurprisingly, the top two topics are “Why isn’t my computer doing anything?” and “What does this actually accomplish?” The first is easier to answer. Thanks to people spreading the word — like the amazing growth of Team Hackaday — there has been a huge infusion of new participants. We could see this happening on the leader boards, but in this AMA we have numbers direct from the source. Before this month there were roughly thirty thousand regular contributors. Since then, several hundred thousands more started pitching in. This has overwhelmed their server infrastructure and resulted in what’s been termed a friendly-fire DDoS attack. The most succinct information was posted b

3D Metal Printer uses Welding Wire

Image
If you’ve seen both a fused filament fabrication (FFF) printer and a wire welder, you may have noticed that they work on a similar basic principle. Feedstock is supplied in filament form — aka wire — and melted to deposit on the work piece in order to build up either welds in the case of the welder, or 3D objects in the case of the printer. Of course, there are a number of difficulties that prevent you from simply substituting metal wire for your thermoplastic filament. But, it turns out these difficulties can be overcome with some serious effort. [Dominik Meffert] has done exactly this with his wire 3D printer project . Extruder cold end using a standard feeder roller For his filament, [Dominik] chose standard welding wire, and has also experimented with stainless steel and flux-cored wires. Initially, he used a normal toothed gear as the mechanism in the stepper-driven cold end of his Bowden-tube extrusion mechanism, but found a standard wire feeder wheel from a welder worked bet

Fail of the Week: In CAD, Remember to Model the Environment

What’s wrong with the above picture? Failure can be an excellent teacher, and [J. Peterson] reminds us all of this when he says to remember to model the environment when designing things in CAD . He contrasts a failure with a success to demonstrate what that means. The failure was a stand for a screwdriver set, shown above. He modeled up a simple stand to hold a screwdriver handle and the bits in a nice, tight formation. He didn’t model any of parts, he just took some measurements and designed the holder. Everything fit just fine, but it had a major ergonomic problem: you can barely reach the handle because it is fenced in by the surrounding bits! Had he modeled all of the parts during the design phase, and not just the part he was making, this problem would have been immediately obvious during the design phase. The contrasting success is an adapter he designed to mount an artistic glass marble to a lit display stand. The stand itself as well as the glass marble were modeled in CAD,

DIY Bagpipes Made From Common Household Items

Image
The bagpipes, most commonly seen in their Great Highland form from Scotland, are a loud and imposing musical instrument. Known for being difficult to practice quietly, they’re not the ideal thing to pick up in these times of quarantine and isolation. But, if you must, here’s how you can craft your own at home! A garbage bag is used as the air bag for this design, readily available and easy to work with. A recorder is then installed into the bag to act as the chanter – the part of the instrument with with pitch is controlled by finger position. A second recorder is then installed as a drone, which produces the continuous harmonizing note typical of bagpipes. A pair of pens are used to create the blowpipe which supplies air to the instrument. Everything is then sealed up with tape and you’re ready to go! While it’s not a great facsimile of an authentic Scottish bagpipe, it does work in the same way and make some noise. It would be interesting to see a talented player handle such a make

Maxing Out Browser Tabs With 2TB Of Memory

Image
Tabbed browsing was a gamechanger, allowing users to effectively browse multiple websites at once without losing context. It proved a better solution than using multiple windows, and was an efficiency boon celebrated by all. Many of us are tab fiends, opening great numbers at a time as a habitual part of our workflow. [Linus] decided to find out just how many he could open on a system armed with a full 2TB of RAM. As may be obvious, setting up a system with 2TB of RAM is no mean feat. Special server-grade RAM modules were sourced, packing 128GB of RAM each, set up for ECC operation. Packing out 16 slots, there’s a performance penalty to addressing so much RAM with a single CPU, but for memory-intensive work, it’s worthwhile. The CPU in question is an AMD 64-core processor, providing plenty of grunt for the task at hand. In testing, the machine began to slow down long before the RAM was full. Beyond 5000 tabs, things began to crawl. At 6000 tabs, it was simply impractical to open more

Teardown of Costco Ceiling Light Reveals Microwave Motion Sensor and Hackable Design

Image
[hclxing] eagerly picked up an LED ceiling light for its ability to be turned on and off remotely, but it turns out that the lamp has quite a few other features. These include adjustable brightness, color temperature, automatic turnoff, light sensing, motion sensing, and more. Before installing, [hclxing] decided to tear it down to see what was involved in bringing all those features to bear , but after opening the lamp there wasn’t much to see. Surprisingly, besides a PCB laden with LEDs, there were exactly two components inside the unit: an AC power adapter and a small white controller unit. That’s it. Microwave-based motion sensor board on top, controller board for LED ceiling light underneath. The power adapter is straightforward in that it accepts 100-240 Volts AC and turns it into 30-40 Volts DC for the LEDs, and it appears to provide 5 V for the controller as well. But [hclxing] noticed that the small white controller unit — the only other component besides the LEDs — had an

SOLID Promises A New Approach To How The Web Works

Image
As it stands on the modern Internet, your data is no longer your own. Your emails, photos, and posts all live on servers owned by large corporations. Their policies give them access to your data, which is mined to generate advertising revenue. And if you want your data back, there are innumerable hoops to jump through. Want it deleted entirely? Good luck. Tim Berners-Lee, original creator of the World Wide Web, is behind the project. Sir Tim Berners-Lee, as the original creator of what became the Web, has drawn issue with the current state of play. To move the ball on the issue, he’s been working on a design for decentralized internet and the efforts have led to the establishment of the Solid project . The goal is to rectify online privacy and ownership issues and give users greater control over their personal data. The big question is how do you do that? When SOLID was announced last year there were few if any details on the approach taken by the program. But since then, more det

Laser Artistry Hack Chat

Image
Join us on Wednesday, April 1 at noon Pacific for the Laser Artistry Hack Chat with Seb Lee-Delisle ! It’s hard to forget the first time you see a laser light show. A staple at concerts starting in the 1980s, seeing a green laser lance out over the heads of tens of thousands of screaming fans to trace out an animated figure or pulsating geometric shapes was pure fascination, and wondering how it was all done was half the fun. As we all know now, it was all done with mirrors, tiny and connected to low-inertia galvanometers capable of the twitchiest of movements, yet precise enough to position the beam of light exactly where it needed to be to create the desired illusion. It was engineering, science, and art all wrapped up into one package. Fast forward to the present day, and laser show technology has certainly advanced. Bulky laser tubes have been replaced by solid-state devices, more colors are available, and galvo designs have improved. The art and artistry of the laserist have gr

Designing Printed Adapters For Power Tool Batteries

Image
Unless you’re particularly fond of having multiple types of batteries and chargers, you’d do well to make sure all your portable power tools are made by the same company. But what do you do if there’s a tool you really need, but your brand of choice doesn’t offer their own version of it? Rather than having to buy into a whole new tool ecosystem, you might be able to design your own battery adapter . Note the locking tab that’s been printed separately. As [Chris Chimienti] explains in the video after the break, the first thing you’ve got to do (beyond making sure the voltages match) is take some careful measurements of the connectors on your batteries and tools. His goal was to adapt a Milwaukee M12 battery to Makita CXT tool, so if you happen to have that same combination of hardware you can just use his STLs. Otherwise, you’ll be spending some quality time with a pair of calipers and a notepad. Once the interfaces have been designed and printed, they are wired together and mounte

Coronavirus Testing Follow-Up: Rapid Immunologic Testing

Image
When I started writing my recent article on COVID-19 testing , I assumed that I would be doing a compare and contrast sort of article. Like many people, I assumed that the “gold standard” test would be the reverse transcriptase-polymerase chain reaction (RT-PCR) test that I described in some detail. And indeed it is, but it’s not without its problems, such as the lack of certified labs and the need for trained technicians to run the samples. I also assumed there would be another test, a simple serological test that could use antibodies to discern if there was an active or even a previous, resolved infection. At the time I wrote the first article, I could find no indication of an immunologic test for COVID-19 (more specifically, a test for SARS-Cov-2, the virus that causes COVID-19). But almost as rapidly as the number of COVID-19 cases rises, the news changes, and it appears that simple, rapidly performed antibody tests are now or soon will be available. They likely won’t replace the

Vinyl Cutter Migrates from Scrapbooks to Gaskets

Image
We know it all too well: another smoothly-operating night in the garage easily halted by a broken component. In the late hours of the night, no hardware store will open its doors. And while waiting may reward the patient, creativity may reward those who act now. That’s exactly where [Justin] found himself one evening: with a torn gasket. Not to be dismayed, he turned to his fiancee [Amy] and the two of them managed to design and cut a perfectly fitting replacement gasket on [Amy’s] vinyl cutter in a  mere matter of minutes. In the video after the break, the two step us through their process in detail. By starting with an image of the existing gasket, they capture a reference image. Some light work in photoshop cleans up everything except the resulting gasket they’re looking for. Finally, sizing “by eye” in the vinyl cutter’s software after measuring an existing dimension gives them sufficient precision to remake a duplicate gasket that’s eye-for-eye indistiguishable from the original

Ammo Can Battery; 50 Ah LiFePO4 Clad in Army Green

Image
For the price of a mid-range Android phone, [Kenneth Finnegan] turned a 50 caliber ammo can into a 50 amp-hour portable power supply . The battery pack uses four 3.5 V LiFePO 4 cells wired in series to achieve a nominal 12 V supply that stands in for a traditional lead-acid battery. The angel of second-hand purchases was smiling on this project as the cells were acquired on eBay in unused condition, complete with bus bars and mounting spacers. All it took to fit them in the case was to grind off the spacers’ dovetails on the outer edges. There are many benefits to Lithium Iron Phosphate chemistry over traditional lead acid and [Kenneth] spells that out in his discussion of the battery management system at work here. While the newer technology has a much better discharge curve than lead-acid, there’s a frightening amount of power density there if these batteries were to have a catastrophic failure. That’s why there are Battery Management Systems and the one in use here is capable of m

Rock Out While You Knock Out Germs

Image
We don’t know about you, but we’re pretty tired of singing two rounds of “Happy Birthday” or counting Mississippi to 20 each time we wash our hands. It’s difficult to do it without thinking about the reason why, and that’s not good for positivity. If you’d rather have your spirits lifted every time you hit the sink, you need a better soundtrack. [Deeplocal] made a soap dispenser that gathers one of your top 20 tunes from Spotify and plays it for 20 seconds while you lather. The best part is that the songs don’t start at 0:00 — the code is written to use the preview clip of each one, so you get the algorithmically-determined best part. Scrubber is a pretty simple build that uses a Raspberry Pi Zero W and a speaker bonnet powered by a LiPo, but we dig it just the same. The switch is adaptable to pretty much any soap dispenser — just stick two pieces of copper tape where they’ll make contact when the pump is pushed down, and solder wires to them. Check out the demo after the break. We

Can You Print With Highlighter Ink?

Image
With huge swathes of people either out of work or working from home, many are now attempting all manner of exciting or silly projects in their downtime. [Emily Velasco] is no exception. She decided to explore the feasability of printing with highlighter ink. It’s a messy business. Wear gloves. The hack starts with a rather ancient inkjet printer, so old that it works with tractor feed paper. [Emily] set about gutting several highlighter pens and squeezed out the ink reservoirs into a ladle. The printer’s ink cartridge was then filled with the fluid, and a test print was fired off. Upon initial extraction, it appears blank. However, with the aid of a UV light, the printed pattern is revealed. It appears that the inkjet is printing a very faint image, such that the system almost works as an “invisible ink”. It’s a fun little hack with an old printer, made easier as it lacks the DRM of newer models. It’d probably be quite achievable with a dot-matrix, too . If you’re similarly tinker

NIH Approved 3D-Printed Face Shield Design For Hospitals Running Out Of PPE

As the world faces a pandemic of monumental proportions, hospitals have been hit hard. The dual problems of disrupted manufacturing and supply chains and huge spikes in demand have led to many medical centres running out of protective gear. Makers have stepped up to help in many ways by producing equipment, with varying results. [Packy] has shared a link to a 3D-printable face shield that, unlike some designs floating around, is actually approved by the National Institute of Health in the USA. The shield consists of a 3D printed headband, which is then coupled with a transparent piece of plastic for the face shield itself. This can be lasercut, or sourced from a document cover or transparency sheet. The design is printable in PLA or a variety of other common materials, and can be assembled easily with office supplies where necessary. The design is available from the NIH here. For those eager to help out, it’s important to do so in an organised fashion that doesn’t unduly take resour
