Water on Mars? Maybe Not

We were as excited as anyone when MARSIS (the Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment announced there was possibly liquid water under the southern polar ice cap. If there is liquid water on Mars, it would make future exploration and colonization much more feasible. Unfortunately, SHARAD (the Shallow Radar) has a new trick that suggests the data may not indicate liquid water after all.

While the news is a bummer, the way scientists used SHARAD to confirm — or, in this case, deny — the water hypothesis was a worthy hack. The SHARAD antenna is on the Mars Reconnaissance Orbiter, but in a position that makes it difficult to obtain direct surface readings from Mars. To compensate, operators typically roll the spacecraft to give the omnidirectional antenna a clearer view of the ground. However, those rolls have been under 30 degrees.

Computer modelling indicated that rolls of 120 degrees would greatly improve the SHARAD data. So far, four of these “very large roll” or VLR maneuvers have allowed more detailed probes of the surface with SHARAD. Unfortunately the new data didn’t back up the early findings. Scientists now think the reflection may be just an unusually flat surface under the ice.

Of course, just because there might not be water in that location doesn’t mean there isn’t any at all. Want to live on Mars? There’s a lot to think about.

Retrofits Done Right: Physical Controls for Heated Seats

We’ve all owned something where one tiny detail drives us nuts: a blinding power LED, buttons in the wrong order, or a beep that could wake the dead. This beautifully documented project fixes exactly that kind of annoyance, only this time it’s the climate-controlled seats in a 2020 Ram 1500.

[projectsinmotion] wasn’t satisfied with adjusting seat heating and ventilation only through the truck’s touchscreen. Instead, they added real physical buttons that feel just like factory equipment. The challenge? Modern vehicles control seats through the Body Control Module (BCM) over a mix of CAN and LIN buses. To pull this off, they used an ESP32-S3 board with both CAN and LIN transceivers that sits in the middle and translates button presses into the exact messages the BCM expects.

The ESP32 also listens to the CAN bus so the new physical buttons always match whatever setting was last chosen on the touchscreen, no mismatched states, no surprises. On the mechanical side, there are 3D-printed button bezels that snap into blank switch plates that come out looking completely stock, plus a tidy enclosure for the ESP32 board itself. Wiring is fully reversible: custom adapters plug straight into the factory harness. Every pinout, every connector, and every wire color is documented with WireVis diagrams we’ve covered before, making this an easily repeatable seat-hack should you have a similar vehicle. Big thanks to [Tim] for the tip! Be sure to check out some of our other car hacks turning a mass produced item into one of a kind.

Anthropic lancia Claude Opus 4.5, il modello di intelligenza artificiale più avanzato

Anthropic ha rilasciato Claude Opus 4.5 , il suo nuovo modello di punta, che, secondo l’azienda, è la versione più potente finora rilasciata e si posiziona al vertice della categoria nella programmazione pratica, negli scenari basati su agenti di produttività.

Il modello ha inoltre registrato miglioramenti significativi nella ricerca approfondita, nell’analisi e nelle attività di presentazione. Opus 4.5 è ora disponibile tramite app, API e in tutti e tre le principali tecnologie cloud.

Il prezzo di Sonnet 4.5 parte da 3 dollari per milione di token in input e 15 dollari per milione di token in output, con un risparmio sui costi fino al 90% con il caching rapido e del 50% con l’elaborazione batch

SOTA nell’ingegneria reale

Nel test SWE-bench Verified, il nuovo modello mostra il risultato migliore tra tutti i modelli di frontiera : Anthropic sottolinea in particolare che Opus 4.5 rappresenta un significativo passo avanti rispetto a Sonnet 4.5, superando compiti che solo poche settimane fa erano considerati “quasi impossibili” per la generazione precedente.

Oltretutto:

• Opus 4.5 è leader in 7 linguaggi di programmazione su 8 su SWE-bench Multilingual.
• I miglioramenti non si limitano al codice: il modello ha registrato notevoli progressi nella visione, nella matematica, nel ragionamento e nelle attività multimodali.
• Su Aider Polyglot, BrowseComp-Plus, Vending-Bench – anche gli indicatori SOTA o simili.

Nel contesto delle intelligenze artificiali, “SOTA” (State of the Art) indica il modello o la tecnica che raggiunge le migliori prestazioni note su uno o più benchmark rilevanti.

Un esempio di miglioramento è stato un caso del benchmark τ²: il modello si sarebbe posizionato in settima posizione, dopo GPT 5.1.

Più forte, più intelligente, più sicuro

Secondo il team, Opus 4.5 è il modello Anthropic più sicuro e resistente alle iniezioni immediate. Ha superato tutti i concorrenti in una serie di test di resilienza alle richieste di attacco. Oltretutto:

• L’esame interno delle prestazioni di Opus 4.5 ha dato risultati migliori di qualsiasi altro test mai eseguito nella storia.
• Grazie a una pipeline di ragionamento migliorata, il modello impiega molti meno token per il ragionamento e la ricerca di soluzioni.

Controllo della forza, compattazione e multi-agente

Opus 4.5 introduce una nuova importante funzionalità per gli sviluppatori: il parametro effort, che determina la profondità del ragionamento:

• Con uno sforzo medio, il modello replica Sonnet 4.5 utilizzando il 76% di token in meno.
• Al massimo, supera Sonnet 4.5 di 4,3 punti percentuali, generando il 48% di token in meno.

Secondo Anthropic, tutto ciò comporta un incremento del 15% nelle attività di ricerca approfondita degli agenti.

Aggiornamenti della piattaforma e del prodotto

Con il rilascio di Opus 4.5 sono stati introdotti i seguenti aggiornamenti:

• Claude Code: la nuova modalità Plan genera piani dettagliati, formula eventuali domande di chiarimento e crea un file plan.md modificabile prima dell’esecuzione.
• Claude Code è ora disponibile anche nell’app desktop, con supporto per sessioni parallele sia locali sia remote.
• Nell’app Claude, le conversazioni estese non si “bloccano” più: il contesto precedente viene compresso automaticamente.
• Claude per Chrome è ora disponibile per tutti gli utenti Max.
• Claude per Excel è stato ampliato in versione beta per gli utenti Max, Team ed Enterprise.

Anthropic ha inoltre aumentato i limiti di utilizzo di Opus 4.5, rendendolo più adatto come strumento di lavoro principale. L’azienda ha dichiarato che gli utenti riceveranno approssimativamente lo stesso volume di token Opus rispetto ai token Sonnet disponibili in precedenza.

Ultrasonic Cutting on the Cheap

When you think of ultrasonics, you probably think of a cleaner or maybe a toothbrush. If you are a Star Trek fan, maybe you think of knocking out crew members or showers. But there is another practical use of ultrasonics: cutting. By vibrating a blade at 40 kHz or so, you can get clean, precise cuts in a variety of materials. The problem? Commercial units are quite expensive. So [Electronoobs] decided to roll his own. Check it out in the video below.

There are dreams and then there’s reality. Originally, the plan was for a handheld unit, but this turned out not to be very practical. Coil actuators were too slow. Piezo elements made more sense, but to move the blade significantly, you need a larger element.

Taking apart an ultrasonic cleaner revealed a very large element, but mounting it to a small blade would be a problem. The next stop was an ultrasonic toothbrush. Inside was a dual piezo element with an interesting trick. The elements were mounted in a horn that acts like an ultrasonic megaphone, if you will.

These horns are available, and he found an off-the-shelf solution with four piezos and a large horn that seemed promising. Driving the elements, though, requires a 40kHz 100VAC signal. His original board didn’t work — but he’s not giving up. But, for now, he used a simple circuit on a breadboard. However, it didn’t make a strong vibration, even with a larger horn.

Comparison with ultrasonic cleaners showed that his output voltage wasn’t enough. The expedient answer was to buy an ultrasonic cleaner kit (who knew they came as kits?) and use the boards from it to drive the horn and the blade. That worked very well.

His current thinking is that the cleaner driver may be too large, since the blade and horn get hot in use. But he still encased it with a 3D printed case and wound up with a usable tool. His next version should be portable and maybe run a little cooler.

Ultrasonic sensors are, of course, super useful. Or you can always levitate tiny things with it.

Testing the Survivability of Moss in Space

The cool part about science is that you can ask questions like what happens if you stick some moss spores on the outside of the International Space Station, and then get funding for answering said question. This was roughly the scope of the experiment that [Chang-hyun Maeng] and colleagues ran back in 2022, with their findings reported in iScience.

Used as moss specimen was Physcomitrium patens, a very common model organism. After previously finding during Earth-based experiments that the spores are the most resilient, these were subsequently transported to the ISS where they found themselves placed in the exposure unit of the Kibo module. Three different exposure scenarios were attempted for the spores, with all exposed to space, but one set kept in the dark, another protected from UV and a third set exposed to the healthy goodness of the all-natural UV that space in LEO has to offer.

After the nine month exposure period, the spores were transported back to Earth, where the spores were allowed to develop into mature P. patens moss. Here it was found that only the spores which had been exposed to significant UV radiation – including UV-C unfiltered by the Earth’s atmosphere – saw a significant reduction in viability. Yet even after nine months of basking in UV-C, these still had a germination rate of 86%, which provides fascinating follow-up questions regarding their survivability mechanisms when exposed to UV-C as well as a deep vacuum, freezing temperatures and so on.

Keebin’ with Kristina: the One with the Elegant Macro Pad

Some people are not merely satisfied with functionality, or even just good looks. These persnickety snoots (I am one of them) seek something elegant, a true marriage of form and function.

Image by [YANG SHU] via Hackaday.IOShould such a person be in the market for a macro pad (or ‘macropad’ if you prefer), that snoot should look no further than [YANG SHU]’s 8-key programmable stream deck-like device.

The main goal here was the perfect fusion of display and feel. I’m not sure that an FDM-printed, DIY macro pad can look any better than this one does. But looks are only half the story, of course. There’s also feel, and of course, functionality.

Yes those are (hot-swappable) mechanical key switches, and they are powered by an ESP32-S2. Drawn on the 3.5″ LCD are icons and text for each switch, which of course can be easily changed in the config app.

There’s a three-direction tact switch that’s used to switch between layout profiles, and I’m sure that even this is satisfying on the feel front. Does it get better than this? Besides maybe printing it in black. I ask Hackaday.

KeebDeck Keyboard Gets Two Thumbs Up

Did you make it to Supercon this year? If so, you hold a badge with a special keyboard — a custom job by Hackaday superfriend [Arturo182], aka Solder Party. Were you wondering about its backstory?

Image by [Arturo182] via Solder PartyUnsatisfied with having to rely on a dwindling stock of BBQ20 keyboards, [Arturo182] created a fantastic replacement called the KeebDeck Keyboard.

This 69-key alphanumeric silicone number has all the keys a hacker needs, plus a rainbow of extras that can be used for macros. According to [Arturo182], the keyboard has a tactile feel thanks to a snap dome sheet underneath the keys, and this makes it more comfortable for long thumb-typing sessions.

Be sure to check out the teasers at the bottom of the KeebDeck page, because there is some really exciting stuff. If you want to build one, GitHub is your friend, pal.

Thanks for the tip, [Wim Van Gool]!

The Centerfold: Controlled Chaos

Image by [Tardigradium] via redditDon’t you just love the repeated primary colors throughout this centerfold? I do, and I think this whole arrangement shows amazing restraint. Controlled chaos, if you will. That’s what [Tardigradium]’s wife calls it, anyway.

Here’s what I know: That’s a Nulea m512 mouse, the keyboard is a KBD Craft Sachiel LEGO number, and that there is a Cidoo macro pad. Best of all, [Tardigradium] hand-painted the speakers. Neat-o!

Historical Clackers: the Gerda Typewriter Was One of Accessibility

Some of us (okay, I) would have thought that most accessibility inventions are fairly recent, say, from the 1960s onward. But consider the Gerda typewriter, which was created in 1919 to enable blind and one-armed victims of WWI to become employable typists.
Image via The Antikey Chop
According to the Antikey Chop, it’s quite possible that the German government helped grease the wheels of this project so that these soldiers would have a usable typewriter with which to get on with life.

Three versions of this index typewriter were produced: a two-handed Gerda, one with a Braille index, and one with an English index. All entered the market the same year, and were produced for a total of three years.

The Gerda’s typewheel was quite like Blickensderfer, and some even had the DHIATENSOR layout. More expensive than last week’s Clacker (75 Marks), the Gerdas for blind and sighted people with two hands cost 195 Marks, and the one-handed edition was 205 Marks. Some of the two-handed models had rectangular, wooden key-tops, and others had round, glass-topped keys.

Finally, Module-Based Keyboard Is a Sensory Nightmare

Image by Future via Games Radar
I’ve been an early adopter of keyboards in the past. This is usually to bring them to your attention, either before they’re released, or just as they’ve come out. And never have I ever had this poor of an experience.

Games Radar recently reviewed a surprisingly not-failed Kickstarter keyboard that actually shipped, the Naya Create. It may not look like it, but the Create is supposed to be a gaming keyboard. What it does look like is mouse-focused, or at least mouse-forward. And that’s the point of it. Evidently.

Those big modules are interchangeable, and there are four of them so far: the Touch (a trackpad), Track (a trackball that falls out reliably), the Tune (a dial), and the Float, which is designed for space mousing around. They sound cool enough, and might actually be the best part of this whole setup.

To fully illustrate my poit I hvemt’t corrected any of the typos experieved typim this semtemve with the Naya Create while tryig to maintain my usual speed.

But according to Games Radar, the Naya Create is so not worth the $850 (!) asking price. It has ‘mushy, low-profile switches’ and clammy caps, and although the reviewer complains about the non-staggered keys, y’all know that those are my preference at this point.

And apparently, by default, Backspace is mapped to the left side. What? Of course, you can remap any key, whenever the software decides to work. Whenever the reviewer tried to save changes, the software would say that the keyboard is disconnected. Wonderful.

Despite these shortcomings, Games Radar says the keyboard is rock-solid aluminium with good hinges. So there’s that. Just, you know, swap out the switches and keycaps, and wait for software updates, I guess.

Got a hot tip that has like, anything to do with keyboards? Help me out by sending in a link or two. Don’t want all the Hackaday scribes to see it? Feel free to email me directly.
