If you ride a motorcycle, you know it is a bit of an art to manage the transmission on a typical bike. Electric motorcycles lose some of that. You usually just have a throttle and a brake. No transmission and, crucially, no clutch. Honda just patented a simulated clutch for those who want the old-school experience, according to [Ben Purvis], writing for Australian Motorcycle News.
This isn’t just a do-nothing lever on the handlebar. There’s haptic feedback to feel when the clutch engages. The motor responds to your actions on the lever. If you pull the clutch in part of the way, the motor loses power up to the point where there is no engine power with the clutch fully in.
Most interestingly, the software understands that when you raise the throttle with the clutch in and then release the clutch, you expect a sudden burst of torque, and it will accommodate the request.
If you are a casual driver, this may seem like a gimmick. However, according to the post, motocross racers rely on precise power control like this.
If you do your own conversion, you could probably do something similar. Or, we suppose, a new build, if you prefer.
Guess what time it is– that’s right, clock time! It’s always clock time, and when it’s clock time at Hackaday the weirder the better. So, how about a water clock that’s not actually a water clock? The water here has nothing to do with timekeeping, but is what’s driving the display. Fair to say that [Strange Inventions] is living up to the name of his YouTube channel.
You can get the idea from the header image: each digit is formed by a fifteen-segment display made up of glass bottles. A stepper-driven peristaltic pump and some membrane-pump boosters fills the bottles as needed with dyed water, while emptying is accomplished simply by having a servo dump the water into a trough. It’s an interesting, albeit messy, way to generate a display.
It wasn’t the original idea– well, the bottles were the original concept, but flipping them was not. Dumping the bottles has the advantage of not needing oodles of pumps or taking five minutes to sequentially fill and drain the bottles at each digit. The linkage to get the servo to flip all nine bottles in one go took some troubleshooting– we can relate, since the physical half of such projects usually is the hard part– but after many modifications the 3D printed mechanism worked, and we think the results are worth it.
If you’re looking for the other kind of water clock, we featured one of those before, too. This one is also of ancient style, but makes use of modern electronics. It occurs to us that if one was really, really ambitious, they could expand this [Strange] project into a very damp flip-dot style display.

A computer the size of a credit card is nothing new. There have been many single-board computers following the familiar dimensions. [Krauseler]’s credit card computer is different, though. It packs an ESP32-C3, e-paper display, NFC reader, and, incredibly, a Li-Po battery into a credit card form factor in three dimensions rather than two. That’s right, this computer is only 1mm thick.
To ensure perfect compliance with the form factor, the enclosure, if that’s what it can be called, is a real NFC card with the middle cut out to take the electronics. The PCB is flexible, and the battery is the thinnest available. The e-paper display is an ultra-thin, flexible variant. A display connector would have been too thick, so a very fine wire-and-solder job was required.
On its own, an ESP32-C3-based computer with an NFC reader and an e-paper display would be a pretty cool project, depending on what software was on it. This one, however, redefines the term “credit card-sized.”
It’s not the first piece of electronics we’ve seen that tries for the full credit card format, but it’s certainly the only one so far to slim down to 1 millimetre.
Thanks [Joey] for the tip!

Humanoid robots are a thing now, and here’s an interesting research project that explores using one as a form of haptic media. Specifically, using a humanoid robot to move a chair while one plays a VR driving simulator.
Here’s how it works: a Unitree G1 robot sits behind a player’s chair and grasps it with its hands. Spherical markers on the chair help the robot’s depth camera know the chair’s position, and real-time G-force signals fed from the simulator (Assetto Corsa, running on PC) tell the robot how much and in what direction to shift the chair to match in-simulator events.
While a humanoid robot (especially one equipped with articulated, human-like hands) makes for an awfully expensive force feedback chair, this approach is interesting because it specifically explores using an already-existing humanoid robot as a general-purpose device. It sits in a chair, looks with its camera, grasps with its hands, and moves the player’s chair in response to game events; no hardware modifications required.
So how well does it work? Pretty well, apparently! Participants found the synchronized motion feedback accurate and highly enjoyable, although it does seem like there were some rough edges. Some testers reported that the sustained motion and constant vibration were tiring, and in some cases seemed to worsen VR sickness.
Still, using a robot in this way seems to be a conceptual success and showcases the potential of humanoid robots as flexible, general-purpose devices. We’ve seen a robot used to provide interactive force feedback in VR before, but a driving simulator makes for a pretty fun demonstration.
The video is embedded below, and for more information, check out the team’s research paper.

Ciao @lemoon ,
vorrei condividere con te degli appunti su una questione che riguarda i post Friendica con il titolo
Come forse saprai già, con Friendica possiamo scegliere di scrivere post con il titolo (come su WordPress) e post senza titolo (come su Mastodon). Uno dei problemi più fastidiosi per chi desidera scrivere post con il titolo è il fatto che gli utenti Mastodon leggeranno il tuo post come se fosse costituito dal solo titolo e, due a capi più in basso, dal link al post originale: questo non è di certo il modo miglior per rendere leggibili e interessanti i tuoi post!
Gli utenti Mastodon infatti hanno molti limiti di visualizzazione, ma sono pur sempre la comunità più grande del Fediverso e perciò è importante che vedano correttamente i vostri post: poter contare sulla loro visibilità è un'opportunità per aggiungere ulteriori possibilità di interazioni con altre persone.
Ecco infatti come un utente Mastodon leggerebbe il tuo post:
Deprimente? Sì, decisamente... In fondo è per questo che stiamo su Friendica e non su Mastodon! 🤣🤣🤣
Fortunatamente, con le ultime release di Friendica abbiamo la possibilità di modificare un'impostazione per rendere perfettamente leggibili anche i post con il titolo. Ecco come fare:
A) dal proprio account bisogna andare alla pagina delle impostazioni e, da lì, alla voce "Social Network" al link poliverso.org/settings/connect…
B) Selezionando la prima sezione "Impostazione media sociali" e scorrendo in basso si può trovare la voce "Article Mode", con un menu a cascataC) Delle tre voci disponibili bisogna scegliere "Embed the title in the body"
Ecco che adesso i nostri post saranno completamente leggibili da Mastodon!

When most people think about vacuum tubes, they picture big glass bottles glowing inside antique radios or early computers. History often treats tubes as a dead-end technology that was suddenly swept away by the transistor in the 1950s. But the reality is much more interesting. Vacuum tube technology did not simply stop evolving when the transistor appeared. In fact, some of the most sophisticated and technically impressive tube designs emerged after the transistor had already been invented.
During the final decades of mainstream tube development, manufacturers pushed the technology in remarkable directions. Tubes became smaller, faster, quieter, more rugged, and more specialized. Designers experimented with exotic geometries, ceramic construction, metal envelopes, ultra-high-frequency operation, and even hybrid tube-semiconductor systems. Devices such as acorn tubes, lighthouse tubes, compactrons, and nuvistors represented a last gasp of thermionic electronics.
Ironically, many of these innovations arrived just as solid-state electronics were becoming commercially practical. Vacuum tubes were improving rapidly right up until the market abandoned them.
By the 1930s and 1940s, vacuum tubes dominated electronics. Radios, radar systems, military communications, industrial controls, and the first digital computers all depended on them. But everyone was painfully aware of their problems.
Traditional tubes were fragile, generated heat, consumed significant power, and suffered from limitations at high frequencies. Internal lead lengths created parasitic inductance and capacitance. At radio frequencies and especially microwave frequencies, those unwanted effects made design difficult.
Military requirements during World War II accelerated development dramatically. Radar systems needed tubes capable of operating at VHF, UHF, and microwave frequencies. Vehicle equipment required devices that could withstand punishment. Computers with tubes suffered from frequent failures, took up entire rooms, and needed special cooling equipment, often bigger than the computer. These pressures drove tube designers into an intense period of innovation.
One of the earliest major departures from conventional tube geometry was the acorn tube. Developed in the 1930s by RCA, the acorn tube got its name from its distinctive shape, which resembled an acorn with wire leads protruding from the base and sides. Unlike ordinary tubes, where the internal elements had relatively long leads, the acorn design minimized lead length to reduce parasitic capacitance and inductance. At high frequencies, this reduction was crucial.
One famous example was the 955 acorn triode. These tubes found use in experimental television receivers, military radios, and laboratory equipment. Acorn tubes also reflected an important trend in late tube development: engineers were increasingly treating tubes not merely as amplifying devices, but as microwave structures requiring careful electromagnetic design.
youtube.com/embed/POeim3qf5Sw?…
If acorn tubes were specialized, lighthouse tubes were positively futuristic. Lighthouse tubes abandoned the classic cylindrical glass form almost entirely. Instead, they used stacked disk-like electrodes arranged in a compact coaxial structure. The resulting geometry minimized transit times and parasitic reactances, allowing operation into microwave frequencies.
The tubes vaguely resembled a lighthouse tower. These tubes became essential in radar systems during World War II and the early Cold War period. Some lighthouse designs could operate in the gigahertz range, something impossible for conventional receiving tubes.
Their construction also introduced new manufacturing techniques. Many used ceramic and metal rather than large glass envelopes. This improved heat resistance and mechanical stability while reducing losses at high frequencies.
In many ways, lighthouse tubes represented the transition from classic vacuum tubes and true microwave devices like klystrons and traveling-wave tubes.
youtube.com/embed/S1lFS_N0kaY?…
Another path of tube evolution focused on durability and compactness. Early tubes used fragile glass envelopes that were easily broken and susceptible to microphonics and vibration. During the 1930s, manufacturers introduced all-metal tube designs. These tubes replaced the glass envelope with a metal shell, improving shielding and mechanical ruggedness.
Metal tubes were particularly attractive for military and automotive applications. Shielding reduced interference, while the smaller physical size allowed more compact equipment layouts.
Hybrid glass-metal constructions also became common. Engineers experimented constantly with new materials and packaging approaches to reduce noise, improve reliability, and extend tube lifespan.
One of the most impressive developments was the subminiature tube. These tiny devices often looked more like oversized resistors than conventional tubes. Some were less than an inch long and designed to be soldered directly into circuits rather than plugged into sockets.
Subminiature tubes emerged largely from military demands during and after World War II. Proximity fuzes for artillery shells required electronics small enough to survive being fired from a cannon. Traditional tubes would simply shatter under the acceleration.
The resulting ruggedized miniature tubes were shock-resistant and compact enough for portable military electronics. After the war, subminiature tubes appeared in hearing aids, portable radios, test instruments, and early miniaturized computers.
youtube.com/embed/jegSJ0039-A?…
One of the most interesting late-stage vacuum tube was the RCA Nuvistor. Introduced by RCA in 1959, the nuvistor represented an attempt to create a truly modern vacuum tube for the transistor age.
Unlike classic glass tubes, nuvistors used a compact metal-and-ceramic construction. They were extremely small, highly reliable, vibration-resistant, and capable of excellent high-frequency performance. They also exhibited very low noise characteristics. At first glance, a nuvistor hardly resembles a traditional tube at all. You could easily mistake these for some other component in a metal can.
Technically, nuvistors were excellent devices. They offered superior performance in many RF applications compared to early transistors, particularly in television tuners, instrumentation, and aerospace electronics.
High-end studio microphones also adopted nuvistors because of their low noise and desirable electrical behavior. Some audiophiles still use nuvistor-based equipment today.
But despite their capabilities, nuvistors arrived too late. Semiconductor technology was improving rapidly. Silicon transistors were becoming cheaper, more reliable, and easier to manufacture in large quantities. Integrated circuits loomed on the horizon. The nuvistor may have been the best small receiving tube ever made, but it was competing against a technology whose economics would soon become overwhelming.
youtube.com/embed/5NJbeDd6sJ4?…
As semiconductor electronics advanced, tube manufacturers attempted another strategy: integration. The Compactron, introduced by General Electric in the early 1960s, combined multiple tube functions into a single envelope. A compactron might contain several triodes, pentodes, or diode sections in one package. This reduced component count, simplified wiring, and lowered manufacturing costs for television sets and other consumer electronics. Of course, tubes with multiple electrodes weren’t new. They dated back to at least 1926. However, GE’s aggressive marketing of the brand was an attempt to prevent designers from defecting to the solid-state camp.
In some sense, compactrons were the vacuum tube answer to integrated circuits. Engineers were trying to achieve greater functional density while keeping tube-based designs economically competitive. GE’s Porta-Color, the first portable color television, used 13 tubes, including 10 Compactrons. They usually have 12-pin bases and an evacuation tip at the bottom of the tube rather than at the top.
Compactrons saw widespread use in televisions, stereos, and industrial electronics during the 1960s and early 1970s. But again, semiconductor integration advanced even faster. The battle was becoming impossible to win.
Even after transistors took over consumer electronics, vacuum tubes remained important in specialized fields. Microwave tubes such as klystrons, magnetrons, and traveling-wave tubes continued to dominate high-power RF applications. Radar systems, satellite communications, particle accelerators, and broadcast transmitters all relied on advanced vacuum devices. In some areas, they still do.
A modern microwave transmitter aboard a communications satellite may still use a traveling-wave tube amplifier because tubes can handle very high frequencies and power levels efficiently.
One misconception about electronics history is that the transistor immediately rendered tubes obsolete after its invention at Bell Labs in 1947. That is not what happened.
Early transistors had many limitations. They were noisy, temperature-sensitive, low-power, and expensive. Tubes often outperformed them in RF circuits, audio applications, and high-power systems well into the 1960s.
For a significant period, designers genuinely did not know which technology would dominate certain markets. Tube designers were still making substantial advances. Nuvistors and Compactrons were not desperate relics; they were serious engineering efforts intended to compete in a changing world.
Ultimately, however, semiconductors possessed overwhelming long-term advantages. Transistors required less power, generated less heat, occupied less space, and could be manufactured using scalable photolithographic processes. Once integrated circuits became practical, the economics shifted decisively. Vacuum tubes could evolve, but they could not shrink into millions of devices on a silicon chip.
The final years of vacuum tube development are often overlooked because history tends to focus on winners. Yet this period produced some of the most elegant and specialized electronic devices ever created. By the late tube era, vacuum tube manufacturing had become quite refined. Engineers could produce tubes with tightly controlled characteristics and surprisingly long operating lives.
youtube.com/embed/Ycr8EJUpKw0?…
Some early transistorized devices still retained subminiature tubes in certain high-frequency or low-noise stages because transistors had not yet surpassed tube performance in every application. This overlap period is often forgotten today. Electronics did not instantly switch from tubes to semiconductors. For years, many systems used both. For many years, a typical ham radio transmitter, for example, would be all solid-state except for the power amplifier finals, which were often a pair of 6146 tubes.
You can, of course, make your own tubes. If you’ve had enough of making your own tubes, maybe try reproducing some of these advanced models.

A data center drained 30M gallons of water unnoticed — until residents complained about low water pressure
Residents in Fayetteville, Georgia, noticed low water pressure last year. The utility discovered two unaccounted-for water connections at one of the nation’s largest data center campuses.
“We get this notification from Fayette County water system saying you need to stop watering your lawns to help conserve water."

if you read the article though, it was a billing messup during a meter transition, for which the water utility takes full responsibility. The data center was billed, and paid.
It was also mainly using the water for construction activities, and says operational water use will be much less. During the period, it was of order 1% of the county water use [Andy Masley calculates], or equivalent to that of about 270 houses.

IT'S MONDAY, AND THIS IS DIGITAL POLITICS. I'm Mark Scott, and will be in Brussels all next week for this conference (where I'll be moderating a panel on May 20 at 11:50 CET.) If you're around and want to grab coffee, ping me here.
— Countries want to build sovereign AI infrastructure. I crunched the numbers to see how much that would actually cost.
— Digital antitrust cases were supposed to rein in the power of dominant players. But when it comes to online advertising, market power is on the rise.
— Spending on government-focused AI systems will rise 35 percent this year to over $80 billion.
Let's get started:
Although the term ‘dry ice’ is generally used for solid CO2, it’s much more accurate to call this ‘dry snow’, as, rather than being actual solid blocks, they are effectively snow that’s been compressed really tightly. While not really necessary for most applications of dry ice, it is possible to make blocks of actual CO2 ice, and thus [Hyperspace Pirate], as someone with a healthy obsession with cold things had to make some of his own.
As a first step, you, of course, have to chill down CO2 in a container, for which Mr. [Pirate] used a Joule-Thomson cryocooler, with a 15% butane, 35% propane, and 50% ethylene gas mixture. Of course, as ethylene is only easy to get if you have a lot of money to spend, you will want to make it yourself from ethanol. This involves boiling and 400°C aluminum oxide to capture the produced ethylene.
With the CO2 pressure chamber cooled in its refrigerated bath, the process didn’t take long. After opening the pressure chamber, the results were interesting to say the least. Although there was definite ice formation along the sides that contacted the metal chamber the closest, the closer to the center, the more the CO2 resembled the usual fluffy, compressed dry ice.
This is encouraging as it shows that it’s definitely possible to make nice ice pucks or cubes, but the method needs further refinement to get more ice and less snow.
