Cyberpunk 2077 fans, the future just got a little more wearable. Someone actually built a real-life cyberpunk jacket complete with flexible OLED screens in the collar, just like the one straight out of Night City. Powered by four bendable OLED panels, dual Raspberry Pi 4s, and a whole lot of clever engineering, the jacket looks like something V would totally wear in the game.

The amazing part? It’s not just a cosplay prop! The screens play smooth synced video, the collar was custom designed and 3D printed to protect the displays, and the final result looks ridiculously close to the in-game design. We’re now officially one step closer to living in Cyberpunk 2077… minus the cyberpsychosis, hopefully.

The ESP32-C5 C-ITS receiver project is an open-source hardware board that gathers data over 802.11p V2X communication from nearby traffic lights, public transportation (buses, trams…), trucks, cars, motorcycles, and even pedestrians to display the results on online maps.

It works using the ITS-G5 protocol built on top of 802.11p V2X (Vehicle-to-Everything), which requires a 5.9 GHz WiFi radio, and makes the ESP32-C5 an ideal candidate. The standard requires a C-ITS Station (ITS-S) found in vehicles (on-board units – OBU) or roadside units (RSU) handling both transmission and reception, and a receiver to handle incoming wireless signals, decode C-ITS (Cooperative Intelligent Transport Systems) messages, and feed the data into online maps like OpenTrafficMap (See screenshot below).

ESP32-C5 C-ITX receiver specifications:

• Wireless module – ESP32-C5-WROOM-1 (ESP32-C5-WROOM-1-N16R8 or ESP32-C5-WROOM-1-N8R8)
  • SoC – ESP32-C5
    • CPU
      • Single-core 32-bit RISC-V processor @ up to 240 MHz
      • Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications
    • Memory – 384 KB SRAM on-chip, 8MB PSRAM
    • Storage – 320 KB ROM
    • Connectivity
      • Dual-band (2.4GHz/5 GHz) 802.11ax WiFi 6, with 802.11b/g/n WiFi 4 standard fallback
        • 20MHz bandwidth for the 802.11ax mode
        • 20/40MHz bandwidth for the 802.11b/g/n mode
        • OFDMA (Orthogonal Frequency Division Multiple Access) mechanism for both uplink and downlink
        • MU-MIMO capability for downlink
        • Target Wake Time (TWT) support
      • Bluetooth 5.0 Low Energy (LE)
      • 802.15.4 radio for Zigbee 3.0 and Thread 1.3

• Ethernet – 10/100Mbps Ethernet RJ45 port via KSZ8851SNL SPI to Ethernet chip
• USB – 2x USB-C ports for JTAG and UART
• Sensor – LM75BDP temperature sensor
• Power Supply
  • 7 V – 58 V input on active/passive PoE
  • TPS2378DDAR for 802.3af/at compliant active PoE
• Dimensions – 93 x 50 mm

The KiCAD 10 hardware design files (schematics, PCB layout, BoM…), the source code for the firmware, and a Node.js script that bridges raw 802.11 packets on NATS (Neural Autonomic Transport System) into tshark (Wireshark command line), and publishes the decoded JSON back to NATS are available on OpenTraffic’s Codeberg account.

The developer gave a talk at Graz Linux Days 2026 (German) about a month ago, and uploaded the presentation slides explaining the project (AI-translated version in English).  At the time, they had already deployed 20 receivers with ranges of several hundred meters in urban areas, and over 10 km with line-of-sight. The ESP32-C5 can be attached to a 4G LTE modem for internet connectivity, and an OpenSCAD enclosure is also provided.

How well this works depends on whether infrastructure like traffic lights and public transport implements 802.11p V2X connectivity, and of course, the number of users deploying such C-ITS receivers.

The ESP32-C5 C-ITS receiver board is not available for sale online in the traditional way, but seeing the interest after their talks, the developers ordered 450 pieces of the board, and you can purchase a board with an optional enclosure for about 20 Euros as part of a group buy. The instructions are on the Wiki, and they only ship to several countries within Europe, or you can pick up yours in Graz, Austria.

A so-called software supply chain attack, in which hackers corrupt a legitimate piece of software to hide their own malicious code, was once a relatively rare event but one that haunted the cybersecurity world with its insidious threat of turning any innocent application into a dangerous foothold in a victim’s network. Now one group of cybercriminals has turned that occasional nightmare into a near-weekly episode, corrupting hundreds of open source tools, extorting victims for profit, and sowing a new level of distrust in an entire ecosystem used to create the world’s software.

On Tuesday night, open source code platform GitHub announced that it had been breached by hackers in one such software supply chain attack: A GitHub developer had installed a “poisoned” extension for VSCode, a plug-in for a commonly used code editor that, like GitHub itself, is owned by Microsoft. As a result, the hackers behind the breach, an increasingly notorious group called TeamPCP, claim to have accessed around 4,000 of GitHub’s code repositories. GitHub’s statement confirmed that it had found at least 3,800 compromised repositories while noting that, based on its findings so far, they all contained GitHub’s own code, not that of customers.

“We are here today to advertise GitHub’s source code and internal orgs for sale,” TeamPCP wrote on BreachForums, a forum and marketplace for cybercriminals. “Everything for the main platform is there and I very am happy to send samples to interested buyers to verify absolute authenticity.”

Bryan Johnson, le millionnaire américain devenu apôtre de la longévité en bonne santé, annonce que sa compagne Kate Tolo va se soumettre à un protocole médical à 2 millions de dollars par an similaire au sien. Objectif affiché : produire des données de santé spécifiquement féminines, là où la recherche clinique en manque cruellement.

If you’ve played Cyberpunk 2077, you might have seen the rad jacket that has a screen in the collar. Once upon a time, such a thing would be solely the preserve of science fiction—you certainly wouldn’t be achieving that look with cathode ray tubes, that much is for sure. However, technology has advanced to the point where [Zibartas] was able to produce just such a jacket in real life.

The key to the build is the advent of the flexible OLED screen. [Zibartas] was able to source four such panels in a smartphone-like aspect ratio, which came in at the hefty price of $300 each. Two Raspberry Pi 4s were enlisted to drive two screens each. The older model Pi was chosen as it was capable of achieving a neat hack to better play smooth video across two displays. A rudimentary sync system was whipped up using GPIO pins to keep video from both Pis playing together. From there, it was simply a matter of figuring out how to create a structure to hold the screens within the large collar of the scratch built cyberpunk-styled jacket. As it turns out they don’t actually flex much in the final install, as they’re held in a 3D printed structure to keep them safe from damage.

The final result is quite something, very accurately recreating the jacket from the game itself. While technically a simple build, actually pulling it off required some delicate work and smart design decisions to make it practical to wear. We’ve featured some other fun jackets over the years, too.

À la Google I/O 2026, Numerama a pu essayer le modèle Genie 3 de Google DeepMind, désormais capable de générer un monde virtuel jouable à partir d'une simple image Google Street View. Une démo bluffante qui ouvre une porte vertigineuse pour le secteur du jeu vidéo… et qui pose aussi de très nombreuses questions.

On Tuesday, biotech startup Colossal announced its newest development on the road to its announced goal: reversing the extinction of species, in this case, avian species. The development itself is essentially an artificial eggshell, one that allows almost the entire developmental process to occur without the shell. The company transferred the contents of eggs to their specially designed container within a day or two of laying and were able to have normal chicks walk away from it.

Beyond its potential utility for Colossal's intended efforts, the work is personally interesting to me because it may solve a problem I faced in my research days. I'm going to start by describing the research problem that Colossal may have solved, before coming back to what it hopes to use its technology to do—and why the company still has a few key hurdles left to overcome.

Watching development

For part of my career, I studied the development of vertebrates using chickens. While they're less closely related to us than something like mice, the basics of their development are largely the same. And, unlike mice, they develop outside of their mother's body. If you're careful, you can chip away a hole in the egg, perform manipulations on the developing embryo, and then seal it back up with some tape. The chicken embryo will keep developing, allowing you to see the impact of what you've done on normal development.

Annoncé à l’occasion de la Google I/O 2026, Gemini Spark est un agent personnel capable d’agir à votre place, en continu, sans que vous ayez à laisser une machine allumée chez vous. Dans un marché encore émergent, Gemini Spark se positionne face à Claude Dispatch d’Anthropic ou Perplexity Computer, avec un avantage infrastructure que ses concurrents peineront à répliquer.

Dans l’univers de la signature électronique, un acteur s’est largement imposé : DocuSign. Mais ce dernier coûte très cher… Entre abonnements mensuels, limitations d’enveloppes et frais annexes (SMS, vérification d’identité, support), la facture peut grimper très vite. Face à ce modèle, DocuSeal propose une approche radicalement différente : open source, gratuit et auto-hébergeable.

DocuSeal : le DocuSign 100% gratuit

Lancée en 2023, DocuSeal est née d’un besoin simple : signer des documents sans abonnement. En quelques semaines, le projet devient une solution complète et aujourd’hui largement adoptée sur GitHub.

Fonctionnellement, DocuSeal couvre l’essentiel (et même plus) :

• Transformation de PDF en formulaires interactifs ;
• Éditeur drag-and-drop avec 13 types de champs ;
• Gestion multi-signataires avec ordre personnalisé ;
• Notifications et rappels automatisés ;
• Signature mobile fluide ;
• Audit complet et vérification des signatures ;
• Modèles et envois en masse ;
• API complète pour intégration SI…

On est loin d’un simple clone, DocuSeal vise clairement les usages professionnels.

Docker pour faciliter l’auto-hébergement

L’un des points forts de DocuSeal, c’est son déploiement. Une simple commande Docker suffit pour lancer une instance complète. Pas de dépendance complexe, pas de SaaS opaque.

Ce choix technique change tout :

• Vos documents restent sur votre infrastructure ;
• Aucun tiers n’accède à vos contrats ;
• Conformité facilitée (RGPD, confidentialité interne) ;
• Scalabilité maîtrisée selon vos besoins.

Dans un contexte où la souveraineté des données devient critique, c’est là aussi un sacré avantage.

Zéro coût, zéro limite

Là où DocuSign facture chaque fonctionnalité, DocuSeal adopte un modèle sans friction :

• Documents illimités ;
• Signataires illimités ;
• Stockage illimité ;
• Aucun coût caché.

Une petite société peut économiser plusieurs milliers d’euros par an… quelque soit la taille de l’équipe. Tout au plus, il faudra passer par un VPS pour quelques euros par mois. A noter que Docuseal propose sur ses serveurs avec une offre gratuite et une payante. Et contrairement à ce que l’on pourrait penser d’un projet open source récent, DocuSeal affiche déjà un niveau de maturité sérieux avec des certifications ISO 27001, SOC 2, HIPAA, ainsi que la conformité au RGPD.

Docker

La façon la plus simple pour profiter de DocuSeal, c’est très certainement l’utilisation avec Docker… par exemple sur un NAS. L’éditeur fournit un docker-compose.yml complet et facile à adapter.

services:
  app:
    depends_on:
      postgres:
        condition: service_healthy
    image: docuseal/docuseal:latest
    ports:
      - 3000:3000
    volumes:
      - ./docuseal:/data/docuseal
    environment:
      - FORCE_SSL=${HOST}
      - DATABASE_URL=postgresql://postgres:postgres@postgres:5432/docuseal

  postgres:
    image: postgres:18
    volumes:
      - './pg_data:/var/lib/postgresql/18/docker'
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: docuseal
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  caddy:
    image: caddy:latest
    command: caddy reverse-proxy --from $HOST --to app:3000
    ports:
      - 80:80
      - 443:443
      - 443:443/udp
    volumes:
      - ./caddy:/data/caddy
    environment:
      - HOST=${HOST}

L’application fonctionne avec la base de données PostgreSQL et Caddy pour le reverse proxy.

En synthèse

DocuSeal n’est pas juste une alternative économique. C’est une remise en question du modèle SaaS appliqué à la signature électronique. Pour les équipes techniques, les startups ou les entreprises sensibles à la confidentialité, c’est une option crédible, robuste et alignée avec les pratiques modernes d’auto-hébergement (lien vers GitHub).

Les cartes perforées, c'est le truc qu'on associe à l'informatique de grand papa. Des bouts de carton avec des trous dedans qui servaient à programmer les ordinateurs des années 1960. Personne n'aurait l'idée d'en utiliser aujourd'hui.

Sauf Bitroller , un bidouilleur qui a eu une autre idée : et si on imprimait des cartes perforées en 3D, qu'on les laissait dans un coffre, et qu'on les relisait avec une simple webcam ?

L'objectif n'est pas de programmer un ordinateur, c'est de stocker des données ultra-sensibles sur un support qui ne risque pas de s'effacer. Genre la clé d'un portefeuille crypto ou un mot de passe maître.

Chaque carte mesure une dizaine de centimètres de côté et stocke 16 octets de données utiles, plus 4 octets de correction d'erreur « Reed-Solomon ». Ce système permet de retrouver l'info même si la lecture est partiellement abîmée. Reed-Solomon, ce n'est pas exotique d'ailleurs, c'est la même famille de correction d'erreurs que celle qui fait tenir vos CD ou vos QR codes face aux rayures. C'est microscopique, oui. Mais pour stocker une clé cryptographique, c'est largement suffisant.

Screenshot

Le génie du projet tient dans la méthode de lecture. Pas de machine industrielle, pas de scanner spécialisé. Juste une webcam, posée au-dessus de la carte, avec un fond noir derrière. OpenCV, la bibliothèque libre de vision par ordinateur que tout le monde utilise pour ce genre de tâche, lit la carte entière d'un seul coup à partir du contraste entre le fond et le plastique blanc. Le créateur fournit deux scripts Python, un pour générer la carte à imprimer, l'autre pour la relire.

Le matériau choisi est du PLA, le plastique standard des imprimantes 3D grand public. C'est honnête pour un prototype, mais pas idéal pour de la longue durée. Bitroller le reconnaît : en acier inoxydable, ses cartes survivraient à un incendie sévère et resteraient lisibles dans plusieurs siècles. Le but n'est pas vraiment de bidouiller, c'est de proposer un vrai support d'archive longue durée.

Face à un vieux papier ou à une clé USB, la différence est évidente. Le papier brûle, la clé USB meurt après quelques années sans alimentation. Une carte perforée en métal traversera les décennies sans broncher. Et le fait que la lecture se fasse avec n'importe quelle webcam évite la galère du lecteur propriétaire qui n'existe plus dans dix ans. Bref, bonne idée. Vous pouvez voir le projet ici .

It can be extremely frustrating to be separated from your pickles or jams by only a powerful twist of a jar top.

Can’t open a jar? Here are my personally tried and tested methods of escalation:

1. Grip and turn harder (and breathe out)

Sounds dumb, but often we have that little bit of extra in us that we didn’t realise. Go on, give it some welly.

You can also try forcibly exhaling as you turn. Just as you naturally do before a strenuous movement like lifting something heavy, a strong breath out helps lock the arm muscles and tighten the core muscles that counter the rotational movement.

Hannah Fry explains this in a video.

2. Ask someone big and strong

Handy strong person around? Perhaps they’re your ticket to the jar’s contents. Plus, thanks to the Benjamin Franklin Effect (sketch in Big Ideas Little Pictures), they’ll probably like you more for asking them—especially if they succeed.

3. Wrap in a tea towel or cloth

A tea towel is surprisingly effective as it:

• can give a better grip than dry hands
• softens the ridges digging into your hands, meaning you can get more purchase with less pain

Both of these mean you can twist it better.

And it also deals with any moisture if that was making it slippery.

4. Use a rubber band

As you try and turn the lid your hand can slip. A rubber band that fits the lid gives you very effective grip. It’s rare that a rubber band doesn’t do the trick for me.

5. Warm the lid with water

For really jars, this trick has almost always got me inside. Run hot water over the metal lid, avoiding the jar if you can. The hot water expands the metal lid very slightly, and more than the glass expands. This can be just enough to loosen it so that one more go, probably with a cloth as it’s now wet, will let you in.

6. Turn to the machines

Still stuck. Time to get a contraption specially designed to grip and give leverage.

Update:

As is so often the case with this project, I get educated by people. A number of people highlighted that the vacuum seal is often the problem—created when the contents is often put in the jar hot. Breaking that seal is key to release the tension. So, several alternative popular methods suggested to me include.

• Using a screwdriver, spoon or blunt knife to get under the rim of the jar lid and lever it open to break the seal. You can also lever it with a can opener, or a device specifically for it like this Lee Valley jar opener.
• Tap the edge of the lid with the back of a knife or on the counter in several different spots—aim for where the little tabs are. Once the seal breaks it will open easily.
• Turn the container and hold the cap—move the bigger object.

I will make it my business to try them.

With regard to the machines, there are many. People shared special grippy mats, tools to pop the tricky child-proof caps, jar keys, and simply 10–12" adjustable pliers.

At least, when jars are mostly glass, if you were really in a pickle, you could probably get into them, which is more than can be said for tins.  Tins are genuine puzzles if you don’t have an opener. I wouldn’t be surprised if someone had starved surrounded by tins of food.

Incidentally, the screw-top lid always strikes me as a pretty incredible achievement—particularly the quarter-turn lids. With a small motion, you can create a seal between metal and glass that protects the contents through rain, shine or throwing around a room. And, usually, with only a little effort to remove it.

Good luck with your jars. Let me know what works for you or if I missed anything.

The vibrobot – a vibrating motor and battery attached to the head of a brush – isn’t truly a robot, since its movement can’t be controlled, but it’s whetted the interest of many future roboticists. With a clever control method, though, it is in fact possible to drive them in any desired direction while using only one motor.

[Namaskar Mitro] based the design of this robot on this research paper; if the vibrating motor is mounted at an angle above the base of the robot, it causes the bot to rotate, and if the motor is mounted off-center from the center of mass, the robot moves in a circle. Crucially, reversing the direction of the motor’s rotation reverses the direction of the robot’s rotation. By rapidly switching the direction of rotation, the bot can move in a series of short, shallow arcs which approximate a straight line.

The robot which [Namaskar] built was based on an ESP-01F microcontroller, which let it be remote-controlled over Wi-Fi. It used a DRF8212 motor driver to control a vibrating pager motor, which was housed inside a 3D-printed enclosure. To move in a straight line, the ESP-01F switches the motor’s direction every 250 milliseconds, which still produces a slightly erratic movement. It can, however, approximately follow a traced path.

This adds to the previous vibrobot control methods we’ve seen: a pair of differentially-driven vibrating motors or a weight-shifting mechanism.

Along with Velcro, zippers have become an integral part of every day life, being a quick and easy way to usually temporarily join fabric together. Which isn’t to say that you cannot do more with the basic zipper concept, including using them to turn floppy 2D shapes into rigid 3D ones, such as with the Y-zipper concept proposed and demonstrated by [Jiaji Li] et al.

Although not a fully new idea, the Y-zipper is compared with a range of similar mechanisms that do not feature the same abilities, including the standard zipper ease of zipping up, the possibility of having curved geometry and automatic actuation.

Plus there is that the Y-zipper is designed from the start to be 3Dprinted, while still following the same basic pattern of interlocking teeth that the slider mechanism alternately pushes together or pulls apart.

By modifying the basic straight design of the flat strips, the resulting zipped-up form can take on a distinct bend, as well as turn into a coil or a screw. With a demonstrated joint design it is then possible to join multiple Y-zipper rods together, which could make for an interesting alternative to traditional pop-up tent supports, for example.

Also demonstrated is the use of TPU to create compliant bridges, as well as the direct integration of fabric, to show the versatility of the technology. With the used materials (PLA, TPU) the researchers estimate a maximum viable length of about 3 meters before the printed structures begin to disintegrate.

A new Ghost in the Shell anime series will premiere globally on Amazon Prime Video, promising the most manga-faithful adaptation of the franchise.

This project is perhaps the single most passive-aggressive thing we’ve ever seen on this site: rather than tell someone directly to ‘shut up’, [Blytical]’s speech jammer lets you hack their brain from across the room to stop them from speaking. It’s also a bit of an object lesson in why you shouldn’t just copy reference implementations without careful study — by his own implementation, [Blytical] was forced to learn a lot more than he intended going into this project.

The brain hack behind it is called ‘delayed auditory feedback’: by feeding their speech back to the target with a short delay — only 50 to 200 ms — it creates a confounding effect that is apparently very difficult to speak through. The array of ultrasound transducers is used to accurately aim the audio by serving as an inaudible, low-spread carrier wave, as we saw in another project this year. A shotgun mike picks up the audio from the speaker you wish to harass, and an array of audio processing circuitry takes care of the rest.

That’s where problems happen, as [Blytical] admits he just tossed some reference implementations onto a PCB without bothering to think too hard about what he was doing. It’s the datasheet version of vibe coding, and it usually goes about as well — sometimes perfectly, but rarely without a lot of troubleshooting. That troubleshooting is really, really hard when you don’t quite understand why things were laid out the way they were on the datasheet. We don’t blame [Blytical], you can learn a lot when you bite off more than you can chew. The fact that he risked this failure mode rather than do the whole thing in software with a Pi says good things about how he’s conducting his education.

It’s a shame, though, because we’ve been waiting to see another one of these speech jammers in action for quite some time. Perhaps someone will try again; the ultrasonic array portion seems solved, so if the delay circuit was the problem, perhaps a tiny tape loop would suffice.

The way that the sense of smell works is that olfactory sensory neurons (OSNs) are wired up to olfactory receptors (ORs) in the nasal epithelium, from which they send signals to the brain. Once arrived there, a hierarchy of processing results in us experiencing the sensation of ‘smelling’. Exactly how the olfactory receptor-to-brain mapping works during development, and whether its physical pattern in the nasal epithelium is replicated in the brain, remained major questions until now. In a study published in Cell by [David H. Brann] and others, many of these questions have now been answered, at least for mice.

As it turns out, the mapping between OSNs and ORs isn’t performed by a random selection process, but instead creates a receptor map that’s closely matched between the nasal epithelium and the brain. What has complicated answering this question up till now is that the nasal epithelium isn’t a flat surface, but a convoluted labyrinth that maximizes surface area to smell better.

The second issue was linking the physical location of OSNs and gene expression in the nasal epithelium. Using a new approach, the researchers showed an intricate patterning in this epithelium, with the basal stem cells from which it regenerates maintaining this patterning. This makes for a system very similar to, for example, the auditory system, where the detection of frequencies in the inner ear, as a linear system, is found to be replicated in the brain.

Although it does not provide us with all the answers yet about how this genetic patterning works, it offers a glimpse at a fascinating system that would seem to be used repeatedly across sensory systems. It may also provide potential treatments for medical conditions affecting the olfactory system, whereby the sense of smell is missing, reduced, or oddly miswired, for example, after a SARS-CoV-2 infection of the olfactory nerve that leads to symptoms such as a constant sensation of a burning smell.

You have to wonder if a better understanding of the nose will revive interest in digitally creating and sending smells?

It’s nice to hide away in our little corner of the internet and talk tech, safely away from the turmoil of world events. Sometimes though, geopolitics intrude even into our space, and Reuters are here reporting on a new concern that will probably affect many Hackaday readers. Conflict in the Gulf of Arabia, and in particular raids on Saudi petrochemical plants, is threatening PCB production far away in China.

Most of us probably have a mental image of tankers sailing through the Strait of Hormuz laden with Gulf crude, off to be processed by refineries somewhere else in the world. Certainly a load of oil takes just that route, but for the Saudis and other oil-producing nations in the region, it also makes economic sense to site petrochemical industries at source. They export the much more valuable refined products, among which is the polymer resin used in PCB production. The Reuters report says that consequent to this and a rise in copper prices, the cost of a PCB in China has risen by 40%. Naturally this doesn’t sound like good news.

Here at Hackaday, when it comes to component shortages this isn’t our first rodeo. We’re in the middle of a memory shortage due to AI companies, and the COVID-era chip shortage is still fresh in our minds. Unfortunately, this type of thing as been a regular of the technology world for decades. Here we are with another one, and should we be worried? In the short term it’s certainly a concern as the Gulf conflict is still searching for an end to its uneasy stalemate, but remembering previous shortages we think that global industry will adapt and expand other sources where necessary. Just as with the similar IC encapsulation resin shortage back in the ’90s, it may eventually be the panic more than the shortage which becomes responsible for the price hikes.

We’ve taken an abstract look at global electronic supply chains before.

A 64-inch display, created by combining two 42-inch panels, features a bezel gap of less than one millimeter, which is nearly invisible in most retail and luxury use cases. This larger display is demonstrated as a sports AR solution for luxury boxes, capable of overlaying player stats, replays, and even live betting odds over the live view of a game.

Another application is an interactive AR box for luxury goods. This setup uses a transparent microLED screen in front of a physical object, such as a signed baseball. Users can interact with a digital twin of the object using gesture controls to rotate or zoom in, providing an interactive experience without needing to handle the sensitive physical item. This highlights the display’s ability to merge digital information with real-world objects seamlessly.

AUO is also bringing microLED technology to the consumer market, referencing their work on a high-brightness smartwatch for Garmin, which is designed for outdoor use in full sunlight. In the mobility sector, the company demonstrated an XR interactive window concept at CES, using the transparent microLED as a canvas for AI-driven information overlays in vehicles.

The main antagonist of Toy Story 5, in theaters this summer, is a green, frog-shaped kids’ tablet named Lilypad, a genius new villain for the beloved Pixar franchise. But if Pixar had its ear to the ground, it might have used an AI kids’ toy instead.

AI toys are seemingly everywhere, marketed online as friendly companions to children as young as three, and they're still a largely unregulated category. It’s easier than ever to spin up an AI companion, thanks to model developer programs and vibe coding. In 2026, they’ve become a go-to trend in cheap trinkets, lining the halls of trade shows like CES, MWC, and Hong Kong’s Toys & Games Fair. By October 2025, there were over 1,500 AI toy companies registered in China, and Huawei’s Smart HanHan plush toy sold 10,000 units in China in its first week. Sharp put its PokeTomo talking AI toy on sale in Japan this April.

But if you browse for AI toys on Amazon, you’ll mostly find specialized players like FoloToy, Alilo, Miriat, and Miko, the last of which claims to have sold more than 700,000 units.
