Typically, when we think about forming metal parts, we think about beating them with hammers, or squeezing them with big hydraulic presses. But what if magnets could do the squeezing? As it turns out—Grumman Aerospace discovered they can, several decades ago! Even better, they summed up this technique in a great educational video which we’ve placed below the break.
The video concerns the development of the Grumman EMF Torque Tube. The parts are essentially tubes with gear-like fittings mounted in either end, which are fixed with electromagnetic forming techniques instead of riveting or crimping. Right away, we’re told the key benefits—torque tubes built this way are “stronger, lighter, and more fatigue resistant” than those built with conventional techniques. Grumman used these torque tubes in such famous aircraft as the F-14 Tomcat, highlighting their performance and reliability.
Before……and after. The part is formed and the coil is destroyed. The video goes on to explain the basics of the EMF torque tube production process. A tube is placed inside a coil, with the end fitting then installed inside. A capacitor bank dumps current through the coil to generate a strong electromagnetic field. This field is opposed by a secondary field generated by eddy currents. The two forces result in an explosive force which drives the tube inwards, gripping into the grooves of the end fitting, and destroys the coil in the process. Grumman notes that it specifically optimized a grooving profile for bonding tubes with end fittings, which maximised the strength of these EMF-produced joints.
This tip was sent in by [irox]. The video itself was posted by [Greg Benoit], who notes his father Robert Benoit was intimately involved with the development of the technique. Indeed, it was useful enough that the technology was licensed to Boeing, generating many millions of dollars for Grumman.
We feature all kinds of machining and forming techniques here, but this sort of forming isn’t something we see a lot of around these parts. Still, we’re sure someone will be Kickstarting a home EMF forming machine before the end of next week.
This project submitted to the 2025 Pet Hacks Contest brings a bit of IoT to your finned friends. Aquassist is a fish feeder that is primarily 3D printed only requiring a servo and a microcontroller to give you remote control of feeding your fish.
The Aquassist consists of just six 3D-printed parts. At its core is an Archimedes screw, a mechanism that ensures consistent portions of fish food are dispensed into the fish tank. A small hopper on top holds the food, and to minimize the part count, all 3D-printed components are designed to be glued together.
The brains of the operation take place in a Wemos D1 mini, a compact ESP8266 board programed using the Arduino IDE. The feeding mechanism relies on an SG90 continuous rotation servo, which rotates the Archimedes screw to dispense food. Unlike standard servos, this model offers ample torque in a small package and can rotate continuously without hitting an angular limit.
The Aquassist is controlled via a web-based application accessible from any device. The D1 Mini connects to Firebase to check the feeding schedule or detect if the “Feed Now” button has been pressed. Users can set feeding times or trigger an immediate feeding through the app’s intuitive interface. Check out a video below to see the Aquassist in action, and check our our other entries into the 2025 Pet Hacks Contest.
[Dmytro] was able to lay his hands on a InfiRay T2S+ camera. It’s a capable thermal imaging unit that comes at a cheaper price than many of its rivals. [Dmytro] decided to pull it apart to see what makes it tick, and he discovered a few interesting things along the way.
Like so much modern hardware, pulling the case apart does require some spudging and levering. Once inside, though, it comes apart in a relatively straightforward manner. Once inside, [Dmytro] notes some similarities between this camera and the Flir Lepton, another affordable thermal camera on the market. He also finds a clone of the Cypress FX2LP chip, which is used for talking USB. There’s also an Gowin FPGA inside, with [Dmytro] suspecting the gateware onboard could be modified. If so, the camera may be a candidate for running open source firmware in future.
What bothered [Dmytro] about this camera, though, was the software. When used with an Android phone, the camera demands the use of a proprietary app with with questionable permissions. It can be used on a regular computer, where it appears as a standard webcam. However, in this mode, the camera fails to self-calibrate, and the images quickly become useless. [Dmytro] worked to hack around this, by figuring out a way to trigger calibrations and run the proper image corrections manually when using the camera without the smartphone app. He also explores techniques to improve the resolution of the thermal measurements made by the camera.
We’ve seen some other neat thermal camera hacks over the years. Video after the break.
It’s been a universal trait among the different faithful Hackaday Hounds who have loped around these parts over the decades, that there is no place warm enough for their tastes. Fire up the stove and the dog is there stretched out in front of it, leaving one to wonder whether our house temperature is being cruel to the mutt, or simply that they are heat sponges with infinite capacity. There’s got to be some joy in doggy circles then at the prospect of [John.r.sheahan]’s heated dog bed, designed in particular with the comfort of an older dog in mind.
In electronics terms it’s a relatively low-tech project, using as it does a 12 volt electric lap blanket aimed at motorists. It’s none the less a hack though, because it has a frame made of PVC pipe to hold it, and a blanked clipped in place. This forms a box-like structure above the sleeping position keeping the dog very comfortable indeed over chilly nights. We’ve cared for more than one geriatric dog over the years, and can see that something like this is vital for their comfort and well-being.
This project is part of the 2025 Pet Hacks contest, so look out for more like it. Alternatively if your faithful friend uses something you made, why not enter yourself!
We’re back in Europe for this week’s Hackaday podcast, as Elliot Williams is joined by Jenny List. In the news this week is the passing of Ed Smylie, the engineer who devised the famous improvised carbon dioxide filter that saved the Apollo 13 astronauts with duct tape.
Closer to home is the announcement of the call for participation for this year’s Hackaday Supercon; we know you will have some ideas and projects you’d like to share.
Interesting hacks this week include a new Mac Plus motherboard and Doom (just) running on an Atari ST, while a LoRa secure messenger and an astounding open-source Ethernet switch captivated us on the hardware front. We also take a dive into the Mouse programming language, a minimalist stack-based environment from the 1970s. Among the quick hacks are a semiconductor dopant you can safely make at home, and a beautiful Mac Mini based cyberdeck.
Finally, we wrap up with our colleague [Maya Posch] making the case for a graceful degradation of web standards, something which is now sadly missing from so much of the online world, and then with the discovery that ChatGPT can make a passable show of emulating a Hackaday scribe. Don’t worry folks, we’re still reassuringly meat-based.

Il fantasma di Donna Olimpia continua a perseguitarmi 😮
Ieri il destino, complice anche l'ukulele e il Monopolele Fest, mi ha portato a suonare di nuovo nei luoghi in cui visse Donna Olimpia, uno dei personaggi storici più influenti e affascinanti della Roma del 1600, e quindi del mondo intero probabilmente. Già qualche anno fa ebbi il piacere di partecipare a una bellissima residenza artistica organizzata da MarteLive presso Palazzo Pamphilj a San Martino al Cimino (VT), la dimora signorile in cui Olimpia Maidalchini morì in esilio di peste nel 1657, residenza durante la quale scrissi delle canzoni dedicate a questo sfaccettato personaggio storico, anche noto come La Pimpaccia e La Papessa, per poi cantarle dal vivo durante uno spettacolo multidisciplinare come restituzione della residenza stessa. Ieri invece con una bella rappresentanza del Monopolele Fest abbiamo suonato sempre dentro Palazzo Pamphilj, ma stavolta a Piazza Navona, in quello che è una vera gemma della Roma barocca, voluta da quel Papa Innocenzo X che tale divenne soprattutto grazie al sostegno proprio di Donna Olimpia, in un'epoca in cui le femmine se volevano contare qualcosa il meglio che potevano fare era tenersi quanto meno un passo dietro a qualche uomo, magari anche meno valente di loro stesse. E così ieri con quelle simpaticissime mattacchione de Le Cumbinate e con tanti altri ottimi artisti, tra cui i miei fratelli Danilo Vignola e Giovanni Gio Didonna, ci siamo ritrovati a fare backstage proprio dentro le stanze in cui Donna Olimpia viveva e riceveva le sue visite. Dal 1920 Palazzo Pamphilj è sede dell'Ambasciata del Brasile, e in effetti quello che si è tenuto ieri è stato un piccolo gemellaggio tra questo paese, da cui proviene uno degli artisti ospiti del Monopolele Fest, ossia il bravissimo Vinicius Vivas, e Monopoli, cittadina costiera perla della Puglia, che settimana prossima ospiterà la quinta edizione di quello che è ormai il festival dell'ukulele più importante del mediterraneo.
Insomma quella di ieri, complice anche l'apparizione per un attimo del fantasma dell'austera Donna Olimpia nella sala del concerto, proprio mentre fuori a un certo punto cominciava a piovere e tuonare, è stata una serata di quelle che non si dimenticano facilmente, anche quando hai qualcosa come 2500 live alle tue spalle 😋

The News
Bluesky is starting to roll out a new feature where people can add their Twitch and YouTube livestreams to their account, and the Bluesky app will display an indicator on your profile that you are live. Bluesky is rolling out the feature slowly, with only a select few accounts being able to go live so far. It is mainly focused on sports communities so far, with the NBA being one of the first partners. Bluesky is taking it slow with this feature, CTO Paul Frazee said that major effort is in verifying if the linked account on the streaming platform is the same person as the Bluesky account. Another concern is moderation, Bluesky is only linking to Twitch and YouTube, as these are platforms with a well-established moderation infrastructure. For example Bluesky wants ATProto streaming platform Streamplace to have solid moderation in place before it is considered to be added as a potential source of livestreams. Similar to how Bluesky has rolled out verification, some core pieces of how going live works as only accessible on ATProto, and available for others to use. Bluesky client TOKIMEKI already added the ability for any user to go live. However, same as with verification, this is only visible to other people who also use TOKIMEKI. The real impact of a livestreaming integration will likely come when the feature becomes more widely available, but for now it is already a good demonstration of Bluesky’s willingness to send traffic outside of their app. While Big Tech platforms are taking greater and greater efforts to stop people from leaving their app, Bluesky is taking the opposite approach, by adding features which make people switch to another app.
Leaflet is a publishing platform where anyone can easily create and publish their own documents, posts and pages. These documents can be shared as simple web pages, with a lot of features for customisation. Leaflet’s latest update is Leaflet Publications, which adds ATProto integration. They describe the update as Leaflet becoming as a social publishing platform. With the update, you can now create a ‘publication’, which is a collection of documents and posts. For this you log into Leaflet with your ATProto (Bluesky) account, so that the data is stored on ATProto on your PDS. This makes Leaflet an ATProto blogging platform similar to WhiteWind. Future plans include for more social integration, such as subscribing, commenting, following and more. The organisation says that the key goals is to build social publishing, and to support creators, with paid subscriptions being “a high priority and on our roadmap”.
A New Social, the organisation behind Bridgy Fed, has launched a dedicated page to for people to manage their account bridging. Bridgy Fed is a piece of software that allows people to ‘bridge’ their account across multiple protocols. This allows people on Mastodon (using the ActivityPub protocol) to interact with people on Bluesky (using AT Protocol). For this, people need to manually opt-in their accounts to be bridged to other networks (largely due to cultural reasons from the fediverse communities). Up until now, doing so was a fairly confusing process that involved manually following other accounts. With the new update, people can log in to Bridgy Fed with the account they want to bridge, and simply turn it on or off. It also has an easier option to update the handles for Mastodon accounts that are bridged to Bluesky: for example, by default my Mastodon account on Bluesky can be found at @[url=did:plc:43qcmg2xbxakj6mp4puqyayv]Laurens Hof[/url], which is a fairly cumbersome handle, to put it mildly. At the settings page I can now change it to any handle I want, similar to how any Bluesky account can change their handle. A New Social is also launching a Patreon as they are working towards financial sustainability, with plans to launch merch soon as well.
Custom feed builder Graze has released an integration with Patreon. This integration gives feed creators two new options. Feed creators can now give members of their Patreon the ability to see their custom feeds without sponsored content. They can also limit access to their custom feed to only members of their Patreon. Custom feeds present a large amount of new design space to explore, and they can be used for a wide variety of purposes. One of those is using custom feeds as a form of community, as Blacksky is doing, for example. Restricting access to a a custom feed to only members of a Patreon is another step in the direction of ‘feeds as communities’.
Grain Social is a new photo sharing app build on ATProto. The app is for creating and sharing galleries of photos. The app uses it’s own lexicon, giving people a space to upload and share photos that do not automatically end up on Bluesky. The app has some simple features right now: a timeline that shows all the galleries and photo’s that are created on the platform, and the ability for people to upload photos and create galleries.
Germ Network is an end-2-end encrypted (E2EE) messaging app that is currently in development. The app has announced that they are working on ATProto integration, where people can use Germ Network with their ATProto account. The actual E2EE messaging happens off-protocol. Germ Network says that they are hoping for a common on-protocol implementation in the future, where Germ Network and other ATProto messaging apps can interoperate. A thread by Germ Network CEO Tessa Brown also illustrates why platforms are interested in integrating with ATProto: getting a new social platform off the ground without an existing social graph is incredibly hard. ATProto provides the possibility for other platforms to tap into an existing social graph. This observation is not new, Bluesky PBC has been explicit that this is one of the advantages and design goals of ATProto. We are now starting to see this play out, with new apps that are starting to come out that use ATProto to bootstrap a social graph.
The developers for Bluesky client Flashes said they are working on the concept of a PDS that runs on mobile phones. The Flashes developers are interested in working together with others on this, and have started a Working Group where they have shared their proposed design.
One of the core ideas of ATProto is that the network is effectively one giant pool of data, where a variety of apps and tools can access the same data and process and present that data in a way that fits them best. A Bluesky post can be viewed in the Bluesky Social app for regular doomscrollingmicroblogging, but the same post can also be opened in a PDS browser tool like PDSls or atp.tools, viewed in Skythread for a threading view, or more. Switching between apps to view the same post in different context is quite cumbersome. at://wormhole is a tool to make this easier, it is an Apple Shortcut that allows easy switching between apps. You can view the same content, using the different context that each app provides. As the ecosystem develops, I’m expecting to see more experimentation and development in this direction.
An update for moderation software Ozone (it can now display, issue, and revoke, verification) as well as a new proposal by Bluesky PBC to expand the set of reporting reasons available to users and labelers.
Streamplace has launched a new tool for OAuth, OATProxy, which helps prevent users being logged out of their apps every few days.
Streamplace redesigned the homepage, and made their first hire after their funding round.
Popsky is a media review app on ATProto, and the app is now available for testing on Android as well as iOS. Popsky also supports Goodreads imports now.
BookHive is another media review platform that added support for Goodreads imports this week.
Jetrelay is a custom designed relay that is intended to serve a large number of clients with high efficiency.
In the Media
Wired has an extensive interview with Bluesky CEO Jay Graber, and Graber answers a wide variety of questions on the network. Some quotes that stood out to me:
Graber says that Bluesky is great at sending traffic to news organisations. Wired themselves confirm this, saying that “The platform has become a top traffic driver and source of new subscribers“. Washington Times reporter Drew Harwell also agrees that Bluesky has become a great drive of referral traffic.
Wired boils down questions of moderation to its core, by asking: “Would you welcome President Trump?” Graber is clear that Bluesky will, saying: “Yeah—Bluesky’s for everyone, and we think that over time, the broader public conversation needs to be on an open protocol. That lets people choose their own moderation preferences. We think that it’s flexible enough to serve every use case and everyone.” The follow-up questions on how Graber relates this to free speech being under thread is worth reading as well.
On growing the team: “In November, during our growth spurt, we were around 20. Now we’re at 25, and we’ll probably pass 30 soon. We’re growing at a pace that’s sustainable to us.”
Graber talks about an upcoming ‘communities’ feature that’s scheduled for the end of the year: “A lot of people don’t realize that Bluesky is a bit like Reddit and Twitter at the same time, because you can build feeds that are essentially communities—the science feed is run by scientists, is moderated by scientists, and has its own rules.” The ability to build custom feeds is also planned to come to within the Bluesky app.
On making money, Graber reiterates the current plans: “Subscriptions are coming soon. The next steps are to look into what marketplaces can span these different applications.”
Some interesting and fun experiments in building on ATProto that caught my eye this week:
A tool to scan your timeline and see how how much every account you follow contributes to your feed. Gives good insight in how dominant the loudest voices can be on your timeline, compared to the Quiet Posters.
Sure why not make your browsing history publicly available on ATProto.
