If you’re not worried about corporate surveillance bots scraping your shopping list and manipulating you through marketing, you can buy any number of off-the-shelf smart speakers for your home. Alternatively, you can roll your own like [arpy8] did, and keep your life a little more private.

The build is based around an ESP32 microcontroller. It connects to the ‘net via its inbuilt Wi-Fi connection, and listens out for your voice with an INMP441 omnidirectional microphone module. The audio data is trucked off to a backend server running a Whisper speech-to-text model. The text is then passed to Google’s Gemini 2.5 Flash large language model. The response generated is passed to the Piper Neural Voice text-to-speech engine, sent back to the ESP32, and spat out via the device’s DAC output and a speaker attached to an LM386 amplifier. Basically, anything you could ask Gemini, you can do with this device.

By virtue of using a commercial large language model, it’s not perfectly private by any means. Still, it’s at least a little farther removed than using a smart speaker that’s directly logged in to your Amazon/Google/Hulu/Beanstikk account. Files are on Github for those eager to dive into the code. We’ve seen some other fun builds along these lines before, too. Video after the break.

Can a shape pass through itself? That is to say, if one had two identical solids, would it be possible to orient one such that a hole could be cut through it, allowing the other to pass through without breaking the first into separate pieces? It turns out that the answer is yes, at least for certain shapes. Recently, two friends, [Sergey Yurkevich] and [Jakob Steininger], found the first shape proven not to have this property.

A 3D-printed representation of a cube passing through itself [image: Wikipedia]Back in the late 1600s, Prince Rupert of the Rhine proved it was possible to accomplish this feat with two identical cubes. One can tilt a cube just so, and the other cube can fit through a tunnel bored through it. A representation is shown here.

Later, researchers showed this was also true of more complex shapes. This ability to pass unbroken through a copy of oneself became known as Rupert’s Property. Sometimes it’s an amazingly tight fit, but it seems to always work.

In fact, it was so difficult to find candidates for exceptions to this that it was generally understood and accepted by mathematicians that every convex polyhedron (that is, every shape with flat sides and no holes, protrusions, or indentations) would have Rupert’s property. Until one was found that did not.
Noperthedron pencil holder
The first shape proven not to be able to pass through itself — known as the Noperthedron — is a vaguely ball-like shape, with a flat top and bottom. A fan has already added a cavity to create a 3D-printable pencil holder version of the noperthedron (shown here) if you want your own.

There are other promising candidate objects (they are rare) that may also lack Rupert’s property, but so far, this is the only proven one.

Shapes with unusual properties are interesting, and we love how tactile and visual they are. Consider Penrose tiles, a tile set that can cover any size of area without repeating. For decades, the minimum number of tile shapes needed to accomplish this was two. Recently, though, the number has dropped to one thanks to a shape known as “the hat.”

I must confess that my mouth froze in an O when I saw [Jeff]’s Typeframe PX-88 Portable Computing System, and I continue to stare in slack-jawed wonder as I find the words to share it with you. Let me give it a shot.

[Jeff] tells us that he designed Typeframe for his spouse to use as a writer deck. That’s good spousing, if you ask me. Amazingly, this is [Jeff]’s first project of this type and scope, and somehow it’s an elegant, yet easy build that’s quite well documented to boot. Whatever Typeframe’s design may borrow, it seems to give back in spades.

Image by [Jeff] via Typeframe.netUse Typeframe for what you will — cyberdeck, writer deck, travel PC — this baby can handle whatever you throw at it. And of course, it’s open source from front to back.

This Raspberry Pi 4B-based productivity machine has all sorts of neat features. The touch screen flips upward at an angle, so you don’t have to hunch over it or carry a mouse around. Want to sit back a bit while you work? The aesthetically spot-on keyboard is detachable. Yeah.

If that’s not enough to get you interested, Typeframe is designed for simple construction with minimal soldering, and the sliding panels make maintenance a breeze.

A little more about that keyboard — this is Keebin’, after all. It’s an MK Point 65, which boasts hot-swap sockets under those DSA Dolch keycaps. See? Minimal soldering. In fact, the only things you have to solder to make the Typeframe your own are the power switch and the status light. Incredible.

Decktility Goes Where You Go

Need something even more portable than the Typeframe? Something that might even fit in your cargo pocket? Decktility could be your answer. You’re gonna have to use your thumbs to type on this one, but that’s the price you pay for ultra portability.

Image by [Ken Van Hoeylandt] via Byte WelderBuilt back in 2023, [Ken Van Hoeylandt] combined the Raspberry Pi CM4 with the BigTreeTech Raspberry Pad 5, and “spent many hours developing a case” that fits perfectly. The idea was to push the limits of a Pi-based handheld without it melting down.

The tricky part about using your thumbs is that the experience can be somewhat lacking. But the Bluetooth keyboard [Ken] used actually looks pretty good, and I say this based on this close-up from GitHub. The keys look responsive and the caps aren’t too shallow.

One of the design challenges centered around the batteries — 18650s, because as [Ken] says, flat Li-Pos get spicy when they short-circuit. Both the 18650s and the screen are somewhat heavy, so everything is balanced with the batteries acting somewhat as handles.

This is a great project, and it seems as though [Ken] learned a lot in the process. Be sure to check out the build log for all the gory details.

The Centerfold: Party Like It’s Nineteen Nine-T9

Yeah, I know, not your conventional centerfold. The cuteness factor of this 12-key macropad got me, as did the terrazzo party background. But there’s slightly more to [Joe Scotto]’s latest build than meets the eye.

Rather than using predictive typing, the ScottoT9 uses QMK tap dance, wherein a single key can do ‘3, 5, or 100 different things’ depending on how many times you hit it in quick succession. [Joe] reports that it’s surprisingly easy get up to speed on the thing.

This RP2040 Pro Micro-based build is completely open source, including those lovely keycaps. But if you want them to look this good, you may want to just buy some.

Historical Clackers: the Diskret Code Typewriter

The Diskret (discreet) code typewriter from 1899 is a stunning German beauty of an index typewriter, far removed from the neon-accented see-through plastic label-maker from the late 80s that I often use.
Image via The Antikey Chop
Yet they are of the same spirit: choose a letter with some pointing device, imprint it with some lever action, and repeat.

Stark aesthetic differences aside, the Diskret does far more than my newfangled index typewriter. Designed with two concentric rings, the inner ring can be spun to allow the user to type in code.

For normal typewritering, the typist chose a letter from the outer ring of characters with a lever, which turned the typewheel mounted behind it. Then they would press down to print, and the carriage would advance by one character width to get ready for the next impression.

To use the Diskret as a cipher machine, the typist would spin the inner ring to create a false index, generating a coded letter. The recipient would have to have a Diskret in the same position in order to read the message. Yes, it’s basic, but it was one of the first code typewriters.

Most of this beautiful machine’s metal components were engraved with Jugendstil, or German Art Nouveau embellishments. It came mounted to a thick wood base, and featured a top with handle. A Diskret cost 75 marks, and, at the time, one mark equaled about $4. So, not exactly cheap, but it’s two typewriters in one.

Finally, Will Gen Alpha Cancel Keyboards Altogether?

No, of course not. But a study by the London School of Economics seems to think that the office drones of 2030 or so will skirt future first-draft keyboard use with AI voice typing tools, like everyday, all the time. And yeah, but they’ll have to use a keyboard to edit. Or, get this — they’ll just send voice notes to their bosses all the time. You know, good old unsearchable audio files that will be a pain to sift through later. Sure.
Gen Alpha stares out the window, arms akimbo, leaving a lengthy voice note for their Gen-X boss who just wants to read messages, and quickly. Image via Jabra
Did I mention that the study was done in collusion with Jabra, an audio-video technology company? They make highfalutin’ headsets and such. Ahem.

Now, I have a little secret — Y.T. has used powerful (and not-so-powerful) dictation tools here and there, especially after the surgery, and I could swear I’ve heard others talk-typing around the Hackaday Dungeon, although I can’t be sure. But I really like the act of typing, especially now that it doesn’t cause me intense, weird pain.

If I may cherry-pick a quote from the Fortune article, I choose this one: “speaking replaces typing because it matches how we think: fast, iterative, conversational.” I say all of that depends on your level of written wit, something that gets refined throughout the course of one’s life by, you know, writing or typing, and then reading, editing, removing, replacing, and so forth until it appears flowy and conversational.

And no, I didn’t speak-type a bit of this column. I missed typing on my Kinesis Advantage too much. See you next week-ish.

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.

Among the many science toys that have fallen out of fashion since we started getting nervous around things like mercury, chlorinated hydrocarbons, and radiation is the spinthariscope, which let people watch the flashes of light on a phosphor screen as a radioactive material decayed behind it. In fact, they hardly expose their viewers to any radiation, which makes [stoppi]’s homemade spinthariscope much safer than it might first seem.

[Stoppi] built the spinthariscope out of the eyepiece of a telescope, a silver-doped zinc sulfide phosphor screen, and the americium-241 capsule from a smoke detector. A bit of epoxy holds the phosphor screen in the lens’s focal plane, and the americium capsule is mounted on a light filter and screwed onto the eyepiece. Since americium is mainly an alpha emitter, almost all of the radiation is contained within the device.

After sitting in a dark room for a few minutes to let one’s eyes adjust, it’s possible to see small flashes of light as alpha particles hit the phosphor screen. The flashes were too faint for a smartphone camera to pick up, so [stoppi] mounted it in a light-tight metal box with a photomultiplier and viewed the signal on an oscilloscope, which revealed many small pulses.

While a spinthariscope is a bit easier to set up, they’re considerably less common among amateurs than are cloud chambers, another way to view radioactive decay. For scientific instruments, though, this project’s scintillator-and-photomultiplier approach is the standard, from tiny gamma ray spectrometers to giant neutrino detectors.

Nessuno stato Palestinese: la via di Netanyahu.

(180)

La posizione del primo ministro israeliano Benjamin #Netanyahu e dei suoi governi rispetto alla nascita di uno stato palestinese è stata storicamente e sistematicamente di netta opposizione. Tale linea, consolidata nel corso di più mandati, si fonda su motivazioni di sicurezza, strategie politiche interne e supporto di alleati significativi come gli #USA, con uno specifico ruolo anche dell'Unione Europea, specialmente negli ultimi anni di conflitto e nella fragile tregua in atto.​

Netanyahu si è sempre opposto in modo esplicito alla nascita di uno stato palestinese, sia in Cisgiordania che nella Striscia di Gaza, sostenendo che la creazione di tale entità comporterebbe gravi rischi per la sicurezza di Israele e porterebbe il territorio sotto l'influenza di Hamas e di altri gruppi considerati terroristici.

Nel corso dei decenni, il leader israeliano ha argomentato che l’origine del conflitto non dipende dall’assenza di uno stato palestinese, ma dall’opposizione all’esistenza stessa di Israele da parte di diverse parti palestinesi e arabe. Tale convinzione ha portato Netanyahu a promuovere politiche di isolamento dell’Autorità Nazionale Palestinese e al rafforzamento di Hamas a Gaza per mantenere la divisione tra i palestinesi: “Chi desidera ostacolare la nascita di uno stato palestinese deve sostenere il rafforzamento di #Hamas”, ha dichiarato in riunioni di partito.​

A partire dal ritorno alla guida di #Israele nel dicembre 2022, il governo Netanyahu ha accentuato la sua opposizione a qualsiasi riconoscimento unilaterale di uno stato palestinese. Nel 2024, la Knesset ha votato formalmente contro la nascita di uno stato palestinese, definendo l’eventuale riconoscimento “un regalo al terrorismo”. Il primo ministro ha ottenuto il sostegno sia dai partiti di destra che da quelli centristi, consolidando una linea che respinge apertamente ogni diktat internazionale su tale questione. Parallelamente, sono state accelerate le operazioni militari a Gaza e l’espansione degli insediamenti in #Cisgiordania, rallentando o impedendo ogni serio negoziato di pace.​

Gli Stati Uniti hanno storicamente sostenuto Israele anche rispetto al veto posto contro il riconoscimento di uno stato palestinese presso le Nazioni Unite. Nell’ultimo conflitto a #Gaza, Washington ha ripetutamente bloccato con il proprio veto risoluzioni ONU che chiedevano l’arresto delle ostilità e l’apertura agli aiuti umanitari, dichiarando che tali pressioni pianificate “indebolirebbero la sicurezza israeliana e rafforzerebbero Hamas”.

Tuttavia, segnali recenti indicano un leggero cambiamento: una parte del Congresso USA ha iniziato a proporre la risoluzione per il riconoscimento dello Stato palestinese, seppur senza concreto esito. La tregua attuale rimane estremamente fragile e subordinata alle dinamiche interne israeliane e alle pressioni internazionali, con il governo di Netanyahu che continua a minare la stabilità e i processi negoziali.​

L’Unione Europea si è mostrata maggiormente incline a sostenere la “soluzione a due stati”, criticando apertamente la politica israeliana contemporanea. Tuttavia, la reale capacità d’influenza della #UE sulle scelte del governo israeliano rimane marginale, sia per le profonde divergenze interne alla stessa Europa che per il peso geopolitico degli Stati Uniti nelle politiche israeliane. La posizione della UE si limita spesso a dichiarazioni di principio e pressioni diplomatiche, risultando poco efficace nel condizionare gli sviluppi concreti sul campo.​

L’opposizione di Netanyahu e del suo governo alla creazione di uno stato palestinese appare più radicata che mai nel contesto attuale. Le strategie di divisione interpalestinese, la retorica sulla sicurezza e la gestione della crisi di Gaza sono pilastri di questa immunità ai cambiamenti internazionali. Gli apparati di potere statunitensi e, in misura minore, europei, nonostante alcuni segnali di evoluzione, continuano a garantire una protezione diplomatica che rende difficile qualunque concreta attuazione della “soluzione a due stati”.#Israele vuole essere l’unico stato nella Palestina. Lo dice con le armi e la distruzione di ogni ragionevole ipotesi contraria.
