If you’re located in the Northeast United States and thought you heard an explosion yesterday afternoon, it wasn’t just your imagination — multiple sources have now confirmed that a 1 meter (3 foot) meteor entered the Earth’s atmosphere and broke up in the air off the coast of Massachusetts, releasing the energy equivalent of 300 tons of TNT.
Well, maybe. The latest update from NASA says it might actually qualify as a meteorite, with radar data indicating that debris from the space rock may have fallen into Cape Cod Bay. For those unfamiliar, the difference between a meteor and a meteorite is whether or not any of the object survived its encounter with the atmosphere and made it down to the surface.
There’s an argument to be made that a larger asteroid would have likely set off some alarm bells as it approached the planet, but the fact that this deep space interloper showed up unannounced is a sobering reminder that our ability to detect incoming threats isn’t nearly as robust as we’d like. Fortunately, it looks like the event didn’t result in any serious damage or injury.
Magnet fishers in Cape Cod are stoked.
Speaking of mid-air threats, here’s a reminder of what not to do on an airliner: on Saturday a flight departing Newark airport for Spain had to turn around when it was discovered a Bluetooth device bearing the name “BOMB” was onboard. There was no actual explosive device found on the plane when it was searched upon its return, and reports are that the whole incident was the result of an Ill-conceived device name on a portable speaker.
The details on this one are interesting, as a first-hand account posted to Reddit would seem to indicate that both the flight crew and teams back at United Airlines headquarters in Chicago were able to see the Bluetooth devices on the plane in real-time. The passengers were actually given several chances to turn off their devices before the order was given to turn the plane around, and at one point the crew claimed they were even able to see the number of Bluetooth devices that were still active.
Admittedly, it could have been as simple as one of the crew members using an app on their phone to see how many discoverable Bluetooth devices they could pick up and reporting their findings back to the home office. But in the modern security climate, it’s not hard to imagine that the aircraft has some form of integrated Wireless Intrusion Detection System (WIDS). Something to keep in mind the next time they ask you to put your gadgets into airplane mode during takeoff.
It seems like every week we’ve been reporting on some service going dark, and today is no different. As pointed out by OMG Ubuntu, Canonical will be shutting down the Ubuntu Pastebin service in June. In fact, originally it was supposed to go offline today, but they’ve pushed the date back by a month due to the response from the community. Turns out giving your users just a few days to pack up their belongings before kicking them to the digital curb isn’t popular. Who knew?
Now granted Hackaday is geared more towards hardware than software, but a search through the database would seem to indicate we’ve never once run a post that linked to Ubuntu Pastebin in the 18 years the service has been available. Conversely, we had pages of results when searching our back catalog for instances of the classic pastebin.com. So we’re actually curious about this one and would love to hear from the readers: how many of you were actually using this service regularly, and will you miss it?
Finally, those in the market may be interested to hear that Wells Fargo will start offering mortgages for 3D printed homes produced by the Texas-based ICON Technologies. They’ve even got a special incentive program lined up for the extruded domiciles, offering a lender credit that can offset some of the closing costs.
This might not sound like that big of a deal, but apparently most banks have been understandably skeptical of the technology and the long-term market for 3D printed homes up to this point. After all, it was just a few years ago that a recently completed 3D printed home in Iowa had to be demolished after the structure fell short of safety standards. As pointed out by CNBC, previous communities produced with ICON’s concrete printing technology had to be financed through the developer.
We’re still not sure that 3D printed homes make a whole lot of sense, but making the technology more accessible is surely a net positive. Even if the current state of the art in house squirting isn’t quite there, you know how the old saying goes: a journey of a thousand miles begins with a single layer.
See something interesting that you think would be a good fit for our weekly Links column? Drop us a line, we’d love to hear about it.
When we think of CRT camera viewfinders, most of us probably imagine the tiny CRTs you’d find in a 1980s camcorder. They’re super cute and a load of fun to play with, but they’re very much a consumer device. Professional cameras of the type you’d find in a studio had their own viewfinders, which were a lot closer to a small TV. They’re about as high quality as it gets for a monochrome CRT, and [Evan Monsma] has done the conversion to a general-purpose monitor.
On one side, this is a very straightforward hack, simply a case of tracing wires to identify the power and video pins. Given a tool battery, the monitor fires up and gives a super-sharp picture. What we like about this is the wooden base he’s made for the thing, at the same time rough-and-ready, and professional-looking from the outside. It has a routed space for the cables, and once mounted flush with the monitor base and given a bit of wood stain, it looks almost as though it was manufactured that way.
It’s likely most of us won’t find a broadcast viewfinder in the trash, instead settling at best for a little Chinese portable TV. But it’s still interesting to see these unusual devices. Perhaps it might make a good cyberdeck.

What’s one to do with some nice little relays of questionable pinout, and prototyping board? How about a quietly clicky 4-bit counter using relay logic with tons of buttons?The register with LEDs and buttons is on the top board, the incrementer on the bottom board.
[Agatha Mallett] made the counter after finding herself in possession of a quantity of relays burdened by terrible documentation (the datasheet shockingly lacks a pinout, and doesn’t even mention the coil being unidirectional). But since the relays are also small and of decent quality, they were a good candidate for a small relay logic-based project.
The key to the build is implementing D-type flip-flops using relays. This is done by holding the coil voltage of each relay between its set and release voltage levels. A small voltage bump will energize the coil, closing the relay and leaving it closed. Conversely, a small negative spike releases the coil, leaving it open. This forms the basis of the counter, and [Agatha] has a separate write-up all about the details of using relays in this way.
Implementing this was rather less straightforward than it may sound because it relies on balancing the coils of many relays on a figurative knife-edge of voltage, but not every component is perfectly identical. A tweaked resistor or capacitor here and there was needed before things settled into reliability.
The end product has indicator LEDs, buttons to increment or clear the current count, and it even has buttons to set or clear individual bits. This is a project that begs to be interacted with, and there’s a short video on the project page so you can watch it go through its paces.

Recently [Throaty Mumbo] took a poke at another daft idea, in the form of loading Sega Genesis games off vinyl records. Although a whacky idea, it’s made possible through the use of a Mega Everdrive Pro and its ability to load games via its USB port, a feature mostly intended for on-the-fly game development without swapping SD cards.
For a few decades in home computing, the loading of software from cassette tapes and similar media was very common. This was due to the low-cost nature of this ubiquitous technology compared to alternatives like cartridges and floppy disks. Even if it was famously unreliable and slow, this accessibility made it a very popular choice. This is where home game consoles were different, as they generally used very fast cartridges, but what if you merge these two worlds?
As demonstrated, a Pico 2 board with its RP2350 MCU is used to convert the audio signal containing the binary data into data for transmission via USB to the Everdrive cartridge. After confirming that it works with a tape drive, he drags in a plastic-y PO-80 5″ record cutter and player, where the mono audio limitation is not a problem.
Unfortunately, this PO-80 turns out to be exactly the kind of toy it looks like, with [Throaty Mumbo] unable to cut and play back a record that gets a clean enough signal to the Pico 2 board, though with a better player and likely record cutter it should work fine. After all, some magazines back in the day came with plastic ‘vinyl’ records that contained programs you could load from your record player.
Although technically a failure, it does demonstrate that if you are very patient, you can totally load Sega Genesis ROMs off a tape or record at a blistering couple of kB/s, tops.

Sottoscrivono tutto l'articolo. In Italia l'idea delle grandi opere costose funziona sempre, ma la verità è che bisognerebbe far funzionare meglio quello che già c'è, e che pesa su centinaia di migliaia do persone.
Oggi il vero punto debole della mobilità milanese non è il centro città, già relativamente ben servito, ma la lentezza del trasporto pubblico di superficie e il pessimo collegamento dell’hinterland.
Il trasporto pubblico di superficie della città è veramente terrificante, specialmente se confrontato con altre città equivalenti.
Prima ancora di scavare nuove gallerie, Milano dovrebbe fare ciò che molte città europee hanno già fatto da anni: dare una priorità reale al trasporto pubblico di superficie.

C'è tutto lo spazio che serve, basta ridurre lo spazio dedicato alle auto.
@Otttoz il che significa bloccare una intera città per poterlo fare (non in contemporanea ovviamente), invece la metro si scava sotto, non modifichi la viabilità e non crei difficoltà alle persone.
Secondo me non è così tanto fattibile ricordo un sacco di linee autobus (la 90 per esempio) che passano su corsia singola...
La metro 4 finita di recente, anche se fatta co TBM, ha comportato anni di disagi e non leggeri. I costi di una metro sono elevatissimi.
La 90 a cui fai riferimento è interessata negli ultimi anni da importanti lavoro per completare la preferenziale su tutto l'anello, che è proprio ciò di cui c'è bisogno.
Molti lavori per dare priorità ai mezzi, poi, potrebbero essere a basso impatto: priorità semaforica, nuove corsie preferenziali, fermate dell'autobus protette.
Non c'è bisogno do "bloccare un'intera città", i disagi ci sono comunque, bisogna decidere come investire le poche risorse perche ne abbiano beneficio la maggior parte delle persone, e che ne consegua una diminuzione dell'auto-dipendenza.
Although LCD displays have been used in almost every type of consumer electronics display over the last two decades, many of these screens have a few downsides that limit their usefulness in certain situations. As any owner of an early digital watch, an early laptop, or an early digital camera will testify, these displays often completely fail in direct sunlight. And, a currently new technology often using inexpensive displays in full sunlight conditions is ebikes, so [Volos Projects] decided to use a unique LCD display to solve this issue.
The display is called a reflective LCD (RLCD) and is actually a fairly old but overlooked piece of technology. Displays like these have a reflective layer that bounces ambient light back to the user, increasing contrast and readability in high light, especially when compared to more common transmissive displays. This build is based on a board from Waveshare, which includes the screen and its driver components, and [Volos Projects] integrated this into a test stand that mimics an ebike’s speed sensor and other hardware like turn signals. The display shows the bike’s speed and a few other indicators, and thanks to the screen, this information can be easily seen in full sun.
Although he doesn’t have it on an actual e-bike yet, he hopes it will be useful for those who want to try out something like this with their substandard e-bike displays. The code he’s used is available on a GitHub page for anyone interested. We’d imagine that a low-cost display like this would pair well with an open-source ebike like this one.

The monitors used on older computers are now becoming difficult to find, as we doubt anything for MDA, CGA, Hercules, or EGA has been manufactured in decades. Even VGA, though there are plenty of surplus flat panels to be found, is not as ubiquitous as it once was. Where does that leave the retrocomputing enthusiast with an ISA PC and no screen? Perhaps [Ian Hanschen] has the answer with the PicoGraph, an ISA-to-USB-to-Displaylink adapter.
In hardware terms, it’s using a PicoMEM, a more general-purpose ISA card for emulating cards with a Pi Pico. The Pico hosts a USB DisplayLink adapter, which can connect to the screen of your choice. The software on the PicoMEM does the heavy lifting and provides MDA, Herc, EGA, and VGA support, as well as support for one of the 1990s Cirrus Logic SVGA chipsets. And yes, it appears to work with DOOM.
The practice of using 2020s microcontrollers to lend functionality to retrocomputers has revolutionised the art. We’ve seen many, with one of the more recent being a minimap add-on for an 8-bit Sinclair Spectrum.

Life's a journey (anche nel marketing), not a destination.
#Wayfinding design (design dell’orientamento): tecnica che sfrutta principi di psicologia cognitiva, neuromarketing e comunicazione visiva in modo efficace e "silenzioso".
Dal punto di vista visual, la dominanza assoluta del rosso restituisce una percezione precisa, perché il #rosso cattura l'attenzione più velocemente di quasi tutti gli altri colori, aumenta il livello di attivazione fisiologica (arousal), comunica urgenza, energia, movimento e direzione ed emerge immediatamente nel campo visivo periferico.
Il contrasto del bianco su rosso è uno dei più leggibili in assoluto.
Il cervello impiega pochissimo tempo a decodificare:
• testo
• simboli
• frecce
Inoltre elabora le forme prima delle parole e riconosce la direzione prima del contenuto, riducendo il #cognitiveload (carico cognitivo): il messaggio non si interpreta, si comprende subito.
Le pareti laterali rosse creano una sorta di “canale visivo”, questo produce un fenomeno chiamato "forced perspective guidance", dove l’attenzione viene letteralmente compressa verso il centro.
Anche se qui non c’è un marchio visibile, il design comunica:
• efficienza
• precisione
• ordine
• velocità
Sono tutti valori associati inconsciamente alla cultura elvetica, alla #svizzeritudine 🇨🇭
In marketing questo si chiama #brandtransfer: l’esperienza fisica trasferisce valori all’ambiente senza bisogno di loghi.
L'analisi neurologica è l'aspetto più intrigante: riscoprire l'acqua calda!
Sistema 1 di #Kahneman
Questa segnaletica parla quasi esclusivamente al "Sistema 1", ovvero al cervello rapido, intuitivo e automatico.
Non richiede ragionamento di nessun tipo, quello che potremmo assimilare all'istinto.
Il messaggio è:
rosso → attenzione
frecce → scendi
testo → conferma
L’intera sequenza viene elaborata in poche centinaia di millisecondi.
Entra in gioco anche l'effetto orientamento attentivo: le frecce sono uno dei simboli più potenti per il cervello umano, senza ragionamento (vedi sopra).
Una freccia:
• orienta automaticamente lo sguardo
• modifica la distribuzione dell’attenzione
• induce una preparazione motoria nella direzione indicata
In parole semplici, il cervello inizia a “muoversi” prima ancora del nostro corpo, prima ancora di essere coscienti di quel che dobbiamo fare.
Non ultima, c'è una grande alleata del #marketing - e dello spirito! La riduzione dell’incertezza.
L’incertezza spaziale genera stress e quando il cervello non sa dove andare:
• aumenta il consumo cognitivo
• cresce il livello di #cortisolo
• diminuisce la soddisfazione dell’esperienza
Ecco, questa installazione elimina quasi completamente l’ambiguità.
Da ricordare anche che questo tipo di aree di servizio può confondere dopo una media permanenza: da che parte si esce? La macchina sta verso Lucerna o verso Milano? Se esco da qui e non trovo la macchina, sono dalla parte giusta?
Qui arriva il livello più alto della comunicazione visiva: il messaggio smette di essere informazione e diventa comportamento.

In 2024, [Jan Roetz] decided to see whether he could 3D print a Benchy – the boat-shaped benchmarking tool used in 3D printer calibration – in less than one minute. Two years later, after experiments with air bearing print beds, dry ice cooling, multi-filament hotends, and more, he’s finally broken the one-minute mark.
There are three primary factors limiting the speed of the printer: the extrusion flow rate, the cooling rate for extruded plastic, and the motion system itself. The printer’s hotend combines four strands of filament in one hotend and can extrude about 400 cubic millimeters of plastic per second. For cooling, an air duct around the nozzle could deliver about 400 liters of air per minute, which left the motion system as the only bottleneck.
The original print bed was on top of an air bearing on a granite base, and its motion could be controlled by cords connected to stepper motors. This whole system had very low friction, but its inertia was too high. [Jan] therefore replaced the build plate with a lighter carbon-fiber frame. This had no air bearing, but it slid between the base granite slab and a glass plate above it, which had an opening above the portion used as a build plate. Even the metal pulleys used on the stepper motors had too much inertia, so [Jan] replaced them with smaller, semi-circular plastic pulleys.
The first test was a sub-60-second dry run to make sure nothing would break. This revealed the need for cable guides to keep them from whipping around (not surprising when they were pulling the bed at an acceleration of 225 G). Finally, [Jan] was able to successfully print several successive 59-second Benchies. The prints weren’t photogenic, but they were mechanically sound and dimensionally correct. [Jan] could have gone even faster, but this degraded the print quality too much.
It’s quite an accomplishment, and an impressive conclusion to a major project; we covered the beginning of the project back when [Jan] was going for parallelization rather than speed. The final print didn’t use it, but he also experimented with dynamic temperature control.

You would think a guitar amplifier would be a straightforward piece of analog electronics. But, of course, these days, everything has firmware, including [mforney]’s Yamaha THR10c. The service manual showed both a UART and JTAG header on the schematic, so as many of us would, he took that as a challenge.
Of course, the production board doesn’t have headers for these ports, but that’s not a real problem. The serial port seemed quiet, but the JTAG port was more productive. This revealed two binary images: a bootloader and the main firmware. Once you have the code, it is a straightforward, if not laborious, process to reverse engineer what the code does.
The next step is to figure out how to load new firmware. You can see in the post that this was done, and custom features sprang into life with custom-patched firmware.
We never get tired of seeing people dig into consumer devices like this. Things like JTAG and the wide availability of JTAG tools have made it easier but no less fun. Of course, there are even more features [mforney] has in mind, but now that’s just a matter of coding.
Mini game controllers with buttons and joysticks that move like the real deal are a pretty cool keychain and fidget toy, but at least for some of us there’s this intrusive thought that tells us that it would be so much cooler if it actually was a functional game controller. Enter [Brux] tearing into a miniature GameCube controller and adding the required guts.
The keychain/fidget toy is made by Backpack Buddies and is one of a range of similar toys that feature buttons you can press and joysticks that move, giving a pretty good start on the externals of the controller. Once cracked open at the seam, some interior redecorating had to be performed to clear space and add something to mount switches onto. Here [Brux] opted to glue SMD switches to custom 3D components in lieu of a PCB. These were subsequently wired up with thin enameled wire, before attaching the original buttons to them following some more plastic surgery.
Some tiny joystick innards were then installed before gluing on the final buttons and joystick caps. As for how it all connects to a real GameCube, here an RP2040 was used to handle the translation of control inputs to the GameCube controller protocol. Then a GameCube controller was sacrificed for its cable and controller connector, but as can be seen in the video it does all work and creates the perfect controller for guests.

The pioneering work done by Alan Turing and others at Bletchley Park in England was perhaps as important in the history of technology as it was the history of the war. Given the last 80-odd years of technological development, their revolutionary work should be within the realms of a student project — which it was, specifically in ECE 5760 at Cornell University. The work was done by [Erica Jiang], [Kelvin Resch], and [Isabella Frank].
Nowadays if someone told you there was a code to be broken, you wouldn’t be reaching for electromechanical devices, but you just might think of trying an FPGA. After all, the programmable gate arrays allow for much faster execution of fixed logic than software running on a traditional CPU. That won’t help much with modern RSA schemes, and for Enigma, it’s massively overkill, but doing it that way was a great learning opportunity for the students.
Their project emulates the whole Bletchley Park cryptography apparatus, not just the Bombe Machine, and if you’re interested in learning about this piece of history you could absolutely do worse than to examine their documentation. If you’re into video, you can check out the final presentation and demo video below. Meanwhile if you’re wondering what the opposition was up to, we have good explainer of the enigma machine here.
