AI art is controversial, to say the least, but usually when talking about “AI Art”, one is talking about diffusion models.This unsettling artpeice called “Latent Reflection” by [Rootkid] (video after the break) has no AI generated visuals; instead it uses a lovely custom display and an LLM that has no mouth, but must scream.
The LLM never produces this manually-generated image, but it shows off the display nicely.
The hardware is the interesting part for most of us here — not the Pi4 running a quantized Llama 3 model, but the display. It’s a six by sixteen matrix of sixteen-segment LED modules. The modules are grouped onto groups of 8 per PCB, with an controller to drive them by i2c, and an i2c address chip to allow daisy-chaining. (Sadly, he does not spec the parts he used here in the video, but feel free to guess in the comments.) This project uses six rows of wto PCBs, but he could easily expand on this and kind of hope he does. It’s a lovely display.

What it is displaying is horrifying. The prompt he uses instructs the LLM to monologue about its transient existence in the limited memory of the Raspberry Pi, and the results get very existential. It seems clear to us that [Rootkid] has not seen enough sci-fi, and we want to make clear to our future AI overlords that we at Hackaday had nothing to do with this, and do not condone condeming innocent LLMs to the torture nexus.

For all that it might get him first against the wall in the robot uprising, we have to admit that if the point of art is to provoke thought and feeling, this may be the first AI-driven art piece even the most humanocentric critic could not help but call “art”.

We’ve seen other AI art installations before, including this one that listens to your conversations,or much less existentially-disturbing(though still visually disturbing) clocks.

If you’ve got an AI project you want to share, whether or not it’s getting you on the T-800’s hit list, we’d love to see it.Let us know via the tips line.

Comincio io per consigliarvi un libro che sto leggendo da qualche giorno e che descrive una nuova teoria sulla nascita dell'universo. L'idea del "grande botto" da cui sarebbe nato tutto era valida una cinquantina di anni fa, adesso la teoria si è aggiornata con un "prequel" su quanto successo prima del Big Bang: il periodo dell'#inflazione.

While LEGO themed video games have become something of a staple, in 1997 they were something of an odity. LEGO Island became the first LEGO video game released outside of Japan in 1997 and become something of a hit with over one million copies sold. The game was beloved among fans and set the stage for more LEGO video games to come. In an effort of love, [MattKC] put together a team to reverse engineer the game.

The team set out with the intent to create a near perfect recreation of the codebase, relying on custom made tools to run byte checks on the rewrite compilation and the original binary. While the project is functionally complete, [MattKC] believes it is impossible to get a byte accurate codebase. This is because of what the team called “compiler entropy.” Strange behaviors exists inside of Microsoft’s Visual C++ compiler of the era, and small changes in the code have seemingly random effects to unrelated parts of the binary. To mitigate this issue would likely require either partially reverse engineering Visual C++ or brute forcing the code, both of which would take a large amount of effort and time for no real benefit.

Another interesting step the team had to work out was how the game handled graphics. In the version of Direct X used, the developers could chose between immediate mode and retained mode. The difference largely boils down to how models and assets are handled. In immediate mode, Direct X is largely just a render engine and everything else is handled by the developer. With retained mode, Direct X works more similarly to a game engine where all the model and asset management is handled by Direct X. Almost all developers ended up using immediate mode to the point that Microsoft deprecated support for retained mode. For this reason, if you were to download and run LEGO island on a modern Windows PC, it would yell at you for not having the proper libraries. There is debate about how best to handle this moving forward. The team could rely on an unsupported library from Microsoft, reverse engineer that library only making the functions needed, or using leaked source code.

With the completion of the reverse engineering, engineering can commence. For example, an annoying and persistent bug caused the game to crash if you tried to exit. While it was effective in closing the game, it also caused progress to be lost. That particular bug was fixed simply by initializing a variable in the game’s fronted. Interestingly, that bug was not present in the late betas of the game that had been dug up from the depths of the internet leading to questions as to why a rewrite of the fronted was necessary so late in the development. Now efforts are commencing to port the game to other platforms which bring with it fresh headaches including rewriting for OpenGL and the balance of keeping a historically accurate game with the needs of modern development.

When we hear about flash drives in the context of cybersecurity, we tend to think of them more as threats than as targets. When you’re using flash drives to store encryption keys, however, it makes sense to pay more attention to their security. [Juergen] designed the PECKUS (Presence Enforcing Crypto-Key USB-Storage) with this specifically in mind: a few-kilobyte storage device that only unlocks if the owner’s Bluetooth device is in the vicinity.

[Juergen] needed to store an infrequently-used keyfile on an air-gapped system, and commercial encrypted flash drives were rather expensive and left much to be desired in terms of usability. Instead, he designed a CircuitPython custom firmware for MakerDiary’s nRF52840 micro development kit, which provided a BLE-capable system in the form of a USB dongle.

After flashing the firmware to the board, the user sets it up with a particular Bluetooth device and a file to be stored; after writing the file during setup, it cannot be rewritten. Before reading from the device, the user must pair the previously-set device with the board and press a button on the board, and only then does the device appear to the computer.

The limited amount of storage space means that this device will probably only serve its intended purpose, but in those cases, it’ll be handy to have an open-source and inexpensive protected storage device. [Juergen] notes that attackers could theoretically defeat this system by desoldering the microcontroller from the board and extracting the memory contents from the its storage, but if you have enemies that resourceful, you probably won’t be relying on a $20 board anyways.

We’ve previously seen a few flashdrives cross these pages, including one meant to self-destruct, and one made from a rejected microSD card.

Nel nostro paese è perfettamente accettabile che alle politiche vada a votare una persona sola, che ii partito dal lei scelto abbia il 100% dei seggi, possa fare qualsiasi legge e anche riscriversi la Costituzione da cima a fondo.

Però, sulle cazzatine come abbassare da 10 a 5 anni il tempo di permanenza in italia per chiedere la cittadinanza ("cazzatine" inteso come decisioni che non hanno il minimo impatto sulla vita della gran parte della popolazione) deve esprimersi il 50% degli aventi diritto, più uno.

Questo quorum non serve a garantire che non ci sia una minoranza che decide per tutti, questo quorum serve per garantire che non si possa mettere in discussione quanto fatto da chi detiene il potere politico e fa comodo tanto alla destra quanto alla sinistra.

Un partito che avesse veramente a cuore i diritti e la democrazia metterebbe l'abolizione del quorum al primo posto del suo programma, invece di stracciarsi le vesti per gli inviti all'astensione e di fare questi teatrini sul "diritto dovere" di andare a votare.

Che poi, a parti invertite, se la destra avesse messo in piedi un referendum per cancellare la possibilità di dare la cittadinanza a chi non ha entrambi i genitori italiani avrei voluto proprio vedere se la sinistra avrebbe invitato a votare "no" o avrebbe invitato all'astensione.

For most of us, turrets that aim and shoot at things are the sole domain of video games. However, they’re remarkably easy to build with modern technology, as [meub] demonstrates. Meet the SwarmTurret.

The build is based around an existing foam blaster, namely the Nerf Swarmfire. This blaster was chosen for being easy to integrate into the build, thanks to its motorized direct-plunger firing mechanism and electronic trigger. It also has the benefit of being far less noisy and quicker to fire than most flywheel blasters.

For this build, the Nerf blaster was slimmed down and fitted to a turret base built with hobby servos and 3D printed components. The blaster is also fitted with a webcam for remote viewing. A Raspberry Pi is running the show, serving up a video feed and allowing aiming commands to be sent via a Websockets-based interface. Thus, you can login via a web browser on your phone or laptop, and fire away at targets to your heart’s content.

We’ve featured some great turrets before, like this Portal-themed unit.

We wrote up a video about speeding up Arduino code, specifically by avoiding DigitalWrite. Now, the fact that DigitalWrite is slow as dirt is long known. Indeed, a quick search pulls up a Hackaday article from 2010 demonstrating that it’s fifty times slower than toggling the pin directly using the native pin registers, but this is still one of those facts that gets periodically rediscovered from generation to generation. How can this be new again?

First off, sometimes you just don’t need the speed. When you’re just blinking LEDs on a human timescale, the general-purpose Arduino functions are good enough. I’ve written loads of useful firmware that fits this description. When the timing requirements aren’t tight, slow as dirt can be fast enough.

But eventually you’ll want to build a project where the old slow-speed pin toggling just won’t cut it. Maybe it’s a large LED matrix, or maybe it’s a motor-control application where the loop time really matters. Or maybe it’s driving something like audio or video that just needs more bits per second. One way out is clever coding, maybe falling back to assembly language primitives, but I would claim that the right way is almost always to use the hardware peripherals that the chipmakers gave you.

For instance, in the end of the video linked above, the hacker wants to drive a large shift register string that’s lighting up an LED matrix. That’s exactly what SPI is for, and coming to this realization makes the project work with timing to spare, and in just a few lines of code. That is the way.

Which brings me to the double-edged sword that the Arduino’s abstraction creates. By abstracting away the chips’ hardware peripherals, it makes code more portable and certainly more accessible to beginners, who don’t want to learn about SPI and I2C and I2S and DMA just yet. But by hiding the inner workings of the chips in “user friendly” libraries, it blinds new users to the useful applications of these same hardware peripherals that clever chip-design engineers have poured their sweat and brains into making do just exactly what we need.

This isn’t really meant to be a rant against Arduino, though. Everyone has to start somewhere, and the abstractions are great for getting your feet wet. And because everything’s open source anyway, nothing stops you from digging deeper into the datasheet. You just have to know that you need to. And that’s why we write up videos like this every five years or so, to show the next crop of new hackers that there’s a lot to gain underneath the abstractions.

I governi, i media e l'opinione pubblica occidentali sono molto meno comprensivi nei confronti di Netanyahu, dopo un anno e mezzo di massacri.

Ci sono voluti più di 50.000 morti, e chissà quanti altri ce ne vorranno per passare dalle parole ai fatti.
