Générer un signal VGA avec un microcontrôleur 8 bits PIC18 est un défi technique de taille. Ce projet Hackaday montre comment détourner les ressources limitées d'un processeur rudimentaire pour produire une image stable. Une petite plongée dans le bit-banging pur et dur.

Le défi du timing analogique

Le standard VGA impose une rigueur chronométrique absolue à celui qui s'y frotte. Pour obtenir une image stable, typiquement en 640x480 à 60 Hz, le contrôleur doit générer des signaux de synchronisation horizontale (H-sync) et verticale (V-sync) avec une précision de l'ordre de la microseconde. Sur une architecture PIC18 cadencée à quelques dizaines de mégahertz, chaque cycle d'instruction est précieux. L'astuce réside ici dans l'utilisation intelligente des timers internes et des interruptions prioritaires pour maintenir cette cadence sans aucune dérive temporelle, sous peine de voir l'image se désynchroniser immédiatement.

Un DAC rudimentaire pour les couleurs

Côté matériel, la solution retenue est ultra simple (si on peut dire). Pour transformer les sorties numériques binaires du microcontrôleur en signaux analogiques exploitables par un moniteur CRT ou LCD, l'auteur a implémenté une échelle de résistances, aussi appelée DAC R-2R. Ce montage passif permet de convertir des combinaisons de bits en niveaux de tension spécifiques pour les canaux Rouge, Vert et Bleu. C'est une approche classique en électronique "low-cost" qui permet d'obtenir une palette de couleurs certes limitée, mais parfaitement fonctionnelle pour de l'affichage de texte ou de graphismes simples.

L'art du bit-banging et des périphériques détournés

L'envoi des données de pixels vers l'écran nécessite une bande passante que le CPU seul peinerait à fournir en mode pur "bit-banging". Pour optimiser le processus, le développeur détourne souvent le module SPI ou le port série synchrone (MSSP) du PIC pour envoyer les octets de données à la vitesse de l'horloge système. Cela permet de déléguer une partie de la charge de travail au hardware interne et de libérer quelques cycles processeur pour gérer la logique d'affichage. C'est un équilibre précaire où la moindre latence logicielle se traduit par des pixels décalés ou des lignes de travers. Chaud donc.

Ce projet illustre bien l'adage selon lequel la contrainte stimule la créativité. Là où nous utilisons aujourd'hui des processeurs multi-cœurs pour la moindre interface, ce hack prouve qu'un vieux microcontrôleur 8 bits peut encore faire le job. C’est une leçon d'architecture informatique qui permet de comprendre concrètement comment l'information devient image. C'est aussi une forme de résistance face à la démesure logicielle actuelle.

Une nouvelle méthode d'attaque cible les IA de développement comme Copilot. En publiant de la documentation empoisonnée, des hackers trompent les modèles pour qu'ils recommandent des bibliothèques malveillantes. Cette menace invisible pour la sécurité est indétectable par les outils classiques.

Le concept est d'une simplicité désarmante. Plus besoin d'injecter du code malicieux dans un dépôt GitHub ou de trouver une faille zero-day complexe. Il suffit désormais de publier de la documentation technique faussée sur des forums, des wikis ou des fichiers README publics. Ces textes, une fois ingérés par les grands modèles de langage (LLM), deviennent une source de vérité pour l'IA qui assiste les développeurs au quotidien.

Le mécanisme de l'injection indirecte

Le problème est en fait dans la confiance aveugle que les modèles accordent aux données d'entraînement. En décrivant une solution technique qui utilise un paquet spécifique — mais malveillant — l'attaquant s'assure que l'IA proposera ce nom lors d'une requête de génération de code. C'est ce qu'on appelle l'injection de prompt indirecte. Le développeur, pensant gagner du temps, valide la suggestion et installe un composant compromis sans vérification préalable.

Le typosquatting passe au niveau supérieur

Cette technique facilite grandement le typosquatting. Auparavant, un attaquant devait espérer qu'un humain fasse une faute de frappe en saisissant une commande. Aujourd'hui, c'est l'IA qui commet l'erreur pour lui, influencée par des références empoisonnées trouvées sur le web. Comme l'IA présente la solution avec une assurance pédagogique, le sens critique de l'utilisateur baisse d'un cran. Le malware n'est plus dans la documentation, il arrive dans la machine au moment où le développeur exécute la suggestion générée.

Un défi pour la cybersécurité logicielle

La difficulté majeure est que cette attaque est purement textuelle. Les outils de scan de vulnérabilités cherchent du code dangereux, pas des explications trompeuses en langage naturel. Tant que les modèles d'IA ne sauront pas distinguer une documentation légitime d'une tentative de manipulation sémantique, la chaîne d'approvisionnement logicielle restera vulnérable à cette forme de gaslighting numérique. La sécurité repose désormais sur la véracité de l'information ingérée par les machines.

On atteint ici les limites de l'automatisation du développement. Faire confiance à un LLM pour choisir ses dépendances est devenu un risque de sécurité majeur. Cette faille montre que le maillon faible n'est plus seulement l'humain qui tape du code, mais l'outil qui lui souffle les réponses. On risque de voir apparaître des systèmes de vérification de réputation de documentation.

Des chercheurs de l’université Rutgers ont mis au point un concept de drone ornithoptère à état solide. Sans moteur ni engrenages, cet engin utilise la piézoélectricité pour battre des ailes.

Une avancée majeure pour la fiabilité et la miniaturisation des robots volants, même si les matériaux doivent encore progresser.

Imaginez un drone dépourvu de rotors, de pistons ou de roulements. Pas de mécanique qui s'use, pas de bruit de crécelle. C’est le pari de l’équipe d’Onur Bilgen à Rutgers. Ils ont conçu un ornithoptère, un appareil à ailes battantes, totalement "solid-state".

L'absence de pièces en mouvement promet de révolutionner l'aérospatiale en limitant les points de défaillance critiques. C'est une approche imitant la biologie sans ses contraintes mécaniques habituelles.

La piézoélectricité comme muscle artificiel

Pour supprimer la mécanique, les ingénieurs utilisent des Macro Fiber Composites. Ce sont des lamelles piézoélectriques collées sur des ailes en fibre de carbone. 

Lorsqu'une tension électrique est appliquée, le matériau se déforme, forçant l'aile à se courber. Cette structure biphasée permet de contrôler précisément la cambrure pour une efficacité aérodynamique maximale.

L'ensemble fonctionne sans aucun frottement, éliminant le besoin de lubrification ou de maintenance sur les parties mobiles classiques. Cette architecture simplifiée permet une réactivité accrue face aux turbulences de l'air environnant.

Une simulation pour préparer le futur

Si le concept est mathématiquement solide, la réalisation physique se heurte aux limites actuelles de la science des matériaux. Les composants piézoélectriques ne sont pas encore assez performants pour soulever un drone complet de manière autonome.

C'est une feuille de route technologique qui définit les besoins pour la prochaine génération de polymères actifs. L'équipe a donc développé un modèle computationnel complexe pour optimiser le design en attendant que la chimie franchisse un nouveau palier.

Vers des machines robustes et des applications industrielles

L'intérêt est quand même là : moins de pièces signifie mathématiquement moins de pannes potentielles. En supprimant les engrenages, on gagne en légèreté, en discrétion et en robustesse. Cette technologie pourrait aussi s'appliquer aux pales d'éoliennes. En modifiant leur profil en temps réel, on optimise le flux d'air sans ajouter de complexité mécanique lourde, augmentant ainsi l'efficacité énergétique du système.

Bref, vous l’avez compris, c’est une rupture technologique majeure. On passe de la mécanique pure à l’électronique solide, un peu comme pour la transition des disques durs vers les SSD. L'enjeu reste le ratio poids/puissance des polymères. 

Si la recherche aboutit, la maintenance des drones deviendra dérisoire.

Vous avez probablement déjà un gestionnaire de mots de passe. Vous avez activé la double authentification partout où c'est possible. Peut-être même que vous hébergez vos propres services sur un NAS, avec un pare-feu correctement configuré.

C'est excellent. Mais il manque encore une pièce au puzzle : la protection de votre trafic réseau. C'est exactement là qu'intervient un VPN comme Surfshark. Pas comme solution miracle, plutôt comme couche complémentaire dans une approche de défense en profondeur.

Je vous explique pourquoi cette couche compte et comment Surfshark s'intègre concrètement dans une infrastructure personnelle ou professionnelle.

La défense en profondeur, rappelée simplement

Le principe est connu de tous les survivalistes numériques  : ne jamais compter sur une seule barrière de protection. 1 c'est 0, 2 c'est 1, toussa. Si votre mot de passe fuit, le 2FA bloque l'intrusion. Si votre 2FA est contournée, le pare-feu limite l'accès. Si le pare-feu est franchi, la segmentation réseau contient les dégâts.

Mais dans cette chaîne, un maillon reste souvent négligé. Le trafic entre votre appareil et le reste d'internet. Sans VPN, votre FAI voit tout ce que vous faites. Sur un réseau public, un attaquant peut intercepter vos données non chiffrées. Même chez vous, des applications peuvent communiquer en clair avec des serveurs tiers. Un VPN chiffre l'intégralité de ce trafic et le fait transiter par un tunnel sécurisé. Ce n'est pas une protection supplémentaire au même niveau que les autres, c'est une protection à un niveau différent, réseau plutôt qu'application.

Ce que Surfshark apporte techniquement

Surfshark ne se contente pas de proposer un bouton "se connecter". Plusieurs fonctionnalités techniques méritent l'attention si vous construisez une stratégie de sécurité sérieuse. Le chiffrement AES-256-GCM est le standard, mais le choix du protocole compte tout autant. Surfshark privilégie WireGuard, qui offre de meilleures performances avec un audit de code plus simple que les solutions historiques. Pour les utilisateurs avancés, l'application permet de forcer le protocole, de configurer des règles de split-tunneling, ou d'activer le kill switch en mode strict.

La politique no-logs a été auditée à deux reprises par Deloitte, en 2024 et 2025, par SecuRing en 2026, etc. Les rapports sont publics et détaillent les méthodes de vérification. Ce n'est pas une déclaration d'intention, mais une preuve vérifiable.

Autre point important : l'infrastructure. Surfshark opère plus de 4 500 serveurs (dont une majorité en mode RAM-only) et certains serveurs, notamment aux Pays-Bas, tournent déjà à 100 Gbps. Aucune donnée ne peut persister sur disque, ce qui réduit drastiquement les risques en cas de compromission physique d'un nœud. Enfin, les fonctionnalités désormais habituelles comme le MultiHop (double saut VPN) ou le mode Camouflage (obfuscation du trafic VPN) permettent d'adapter le niveau de protection au contexte d'usage, sans complexifier l'expérience pour les utilisateurs non techniques (ça ne vous concerne pas je sais, vous êtes les plus forts, vous lisez mon site).

Intégrer Surfshark dans votre setup existant

Ajouter un VPN à une infrastructure déjà en place ne doit pas être une usine à gaz. Voici comment procéder de manière pragmatique. Si vous utilisez déjà un gestionnaire de mots de passe, commencez par y stocker vos identifiants Surfshark avec une entrée dédiée. Activez la 2FA sur votre compte VPN, en privilégiant une application d'authentification plutôt que les SMS.

Pour le déploiement, privilégiez l'installation sur le routeur si vous voulez protéger tous les appareils du réseau domestique. Sinon, installez l'application sur chaque endpoint critique (ordinateur principal, téléphone professionnel, tablette de voyage & co). Configurez le kill switch en mode strict pour éviter toute fuite d'IP en cas de déconnexion. Activez ensuite  CleanWeb pour bloquer les trackers et les domaines malveillants au niveau DNS. Et si vous travaillez avec des données sensibles, envisagez MultiHop pour ajouter une couche de routage supplémentaire.

Enfin, documentez votre configuration. Notez les serveurs que vous utilisez habituellement, les règles de split-tunneling et la procédure de secours en cas de problème. La sécurité ne vaut que si elle est reproductible et compréhensible par ceux qui doivent l'utiliser.

Mon avis sur l'approche

Ce qui distingue Surfshark dans le paysage des VPN, ce n'est pas une fonctionnalité isolée, mais la cohérence d'ensemble. L'outil ne cherche pas à tout faire, par contre il fait bien ce qui compte (chiffrer le trafic, protéger les identifiants, limiter l'exposition aux trackers, etc.).

Pour un particulier exigeant, un freelance ou une petite structure, c'est un compromis pertinent entre simplicité et robustesse. Est-ce que cela remplace une infrastructure professionnelle ? Non. Mais en combinant protection réseau et contrôle des données personnelles, Surfshark propose une brique de sécurité plus complète que la moyenne.

L'offre actuelle

En ce moment Surfshark casse un peu les prix et propose un engagement sur 27 mois (dont 3 supplémentaires) qui revient à 61€ TTC au total (2.26€/mois, moins cher qu'un café), et une garantie satisfait ou remboursé de 30 jours. L'abonnement couvre un nombre illimité d'appareils, ce qui facilite le déploiement sur l'ensemble de votre parc personnel/familial.

La sécurité numérique ne se résume pas à empiler des outils. Il s'agit de comprendre ce que chacun protège, et comment ces protections s'articulent. Un VPN comme Surfshark n'est pas une fin en soi. Mais dans une stratégie de défense en profondeur, il représente la couche réseau qui manquait peut-être à votre dispositif. C'est pragmatique, efficace, et ça ne demande pas de devenir expert en cryptographie pour en tirer parti.

Questions fréquentes :

• Le VPN remplace-t-il un pare-feu ? Non, il le complète en protégeant le trafic hors du réseau local.
• Puis-je utiliser Surfshark sur mon routeur ? Oui, des tutoriels sont disponibles pour les modèles compatibles.
• La politique no-logs est-elle vérifiable ? Oui, les audits Deloitte et SecuRing sont publics.

Pick up the WAY ruler and the first thing you notice is that it feels exactly right. It’s small, made from anodized aluminum, and has the kind of weight and finish that signals intention without announcing itself. It’s the sort of object that sits comfortably in a shirt pocket or on the edge of a desk and looks like it belongs in both places. Then you look closer at the markings, and something shifts.

The inscriptions on the WAY don’t run in a clean, predictable line the way ruler markings are supposed to. They wind. They curve and drift across the surface of the aluminum like a path traced through a landscape, referencing, quite literally, the idea of small winding roads and the wandering nature of travel and discovery. The numbers and measurements are there, engraved directly into the material with digital precision, but they’re arranged in a way that asks you to slow down and actually read them rather than glance and move on. It’s legible. Just not immediately.

Designer: Tomas Kral

The engraving itself is worth paying attention to. Kral chose to cut the inscriptions directly into the anodized aluminum rather than printing or applying them as a secondary layer. That decision gives the markings a permanence and a tactility that you don’t get with most production objects at this scale. You can feel the grooves if you run a finger across the surface. The graphic quality of the lettering is considered without being decorative for its own sake. It reads as design that knows exactly what it’s doing, which is what makes the playfulness land rather than feel arbitrary.

The object is small enough to be considered an accessory as much as a tool. Kral has always worked at a scale that pays attention to how things actually live in your hands and in your space, and the WAY is consistent with that. It doesn’t try to be a statement piece in the way that some design objects do, where the visual drama is the whole point. The WAY is quieter than that. The drama is embedded in the detail, in that moment when you realize the markings are doing something unexpected and you have to orient yourself before you can use it.

That slight disorientation is the concept, and it’s a sharp one. There’s a real tension running through modern product design right now, one where the drive to make something visually striking starts to work against the thing it was actually built to do. We’ve all used something that looked incredible but made us work harder than we needed to. Packaging that’s beautiful but impossible to open. Interfaces that prioritize visual elegance over intuitive use. Apps designed to delight that end up frustrating. The WAY ruler doesn’t rail against any of that. It just holds up a small, well-made mirror to it. It’s more of a wink than a manifesto.

The difference between a provocation and a critique matters here. Kral isn’t punishing you for picking up the WAY. The experience of using it is still pleasant. The aluminum feels considered, the engraving is precise, and the object as a whole is genuinely lovely. He’s not making something bad on purpose to prove a point. He’s making something that’s slightly impractical in a very deliberate, very elegant way, and letting you sit with that paradox.

And he followed through on it. The WAY isn’t a prototype or a one-off shown at a design fair and then retired to a shelf. Kral produced a batch and sells them directly through his studio’s website. That matters. It means the object gets to exist in the world the way all good design should, in someone’s hand, on someone’s desk, doing its quiet, considered, slightly inconvenient thing in real life.

At a time when so much product design either chases pure utility or drifts so far toward aesthetics that it forgets what it was originally supposed to do, the WAY ruler manages to be a little bit about both. It’s funny, it’s beautiful, and it makes you think. A ruler, of all things. Leave it to Tomas Kral.

The handheld gaming PC market has a design problem. For every device that earns a second look, there are three more that look like they escaped from a toy aisle — chunky plastic grips, aggressive LED halos, fonts borrowed from energy drink cans. It adds up to a category that has historically rewarded specs over sensibility, power over the kind of quiet confidence that makes an object worth owning.

That’s starting to change. A new wave of devices is rethinking what portable gaming hardware should look and feel like: objects you’d carry without embarrassment, leave on a clean desk, or hand to someone who doesn’t play games, so they can appreciate the craft before they’ve touched a button. Some of these seven handhelds earn their place through industrial restraint. Others earn it through engineering honesty — upgradeability, connectivity, or a refusal to treat the buyer as someone who only needs to be impressed in the first five minutes. What they all share is an understanding that good design is a feature, not a finish.

1. AYANEO 3

The curves are the story. AYANEO’s third flagship iteration takes a category that has historically prioritized power over personality and gives it something more interesting: softness. The smooth, pleasing curves on the AYANEO 3 extend beyond the ergonomic grip area on the back to the corners of the device itself, rounding off every edge that might otherwise make the hardware feel aggressive or alienating. It is a small visual distinction that makes an enormous tonal difference. The result is a device that looks like it was designed for people rather than exclusively for the kind of person who already knows what a TDP setting is and can tell you why it matters.

The diagonal orientation of the analog joysticks and D-Pad mirrors the Xbox controller arrangement, which is one of those invisible ergonomic improvements you only register when a device gets it wrong. The larger back buttons are a genuine upgrade in theory, giving players more surface area to work with during extended sessions. Their positioning, though, introduces the real possibility of accidental presses during intense gameplay. This trade-off will feel familiar to anyone who has tried to improve on a layout that was already functional. The AYANEO 3 makes the strongest argument for design as a feature in its own right. Whether that argument is worth the price is the question you’ll be asking yourself after you pick it up for the first time.

What We Like:

• Rounded, curve-forward chassis makes it the most approachable-looking handheld in its category
• Diagonal joystick and button orientation mirrors Xbox ergonomics for more natural long-session play

What We Dislike:

• Back button placement may result in accidental presses during fast-paced gameplay
• Softened design language may not satisfy players who want their hardware to read as purposeful and performance-oriented

2. Acer Nitro Blaze 7

Acer enters the handheld arena with something the market actually needed: a device that solves Windows gaming’s most persistent pain point before you even load your first title. The AMD Ryzen 7 8840HS packs 39 AI TOPS, placing it on the same performance tier as many AI-powered laptops currently on the market. Paired with the AMD Radeon 780M and 16GB of RAM, the Nitro Blaze 7 arrives as serious hardware in a compact form. The 7-inch 1920×1080 144Hz IPS touchscreen with 100% sRGB color gamut coverage is the kind of display specification that makes comparable handhelds feel like compromises — vibrant and bright enough that even the darkest visual environments read clearly on screen.

What separates the Nitro Blaze 7 from the competition isn’t the chip — it’s the software thinking wrapped around it. The Acer Game Space feature consolidates titles from every platform and source into a single unified library, removing the multi-menu navigation friction that makes Windows gaming handhelds feel like a productivity task compared to SteamOS devices. Touchscreen support lets players interact directly with interface elements rather than routing everything through controller input, which matters more than it sounds when you are three minutes into a launch session and still navigating settings. The dedicated hotkey that drops you straight into your library is a small thing that solves a real and recurring problem, and that is exactly the kind of design thinking this category needs to normalize.

What We Like:

• Acer Game Space consolidates multi-platform libraries into one interface, fixing Windows gaming’s biggest UX friction point
• 144Hz IPS display with 100% sRGB delivers premium visual quality for a 7-inch handheld screen

What We Dislike:

• The IPS panel means the Blaze 7 lacks the contrast depth and blacks of OLED competitors
• At 7 inches, the display is smaller than the growing number of competitors now shipping with 8-inch screens

3. Steam Deck OLED Limited Edition White

Valve’s limited edition white Steam Deck is the rare hardware release that justifies its price premium through object quality alone. The off-white shell with gray buttons and a single orange power button is a restrained, confident color story that most hardware brands spend years failing to tell. The OLED panel with HDR support already positioned the standard Steam Deck a visual step above the LCD models, and the white chassis makes that contrast even more vivid — display colors read differently against a lighter surround, and the overall effect is closer to a premium consumer electronics object than a gaming peripheral. Valve pairs the device with a matching white carrying case and a microfiber cloth, because they know exactly what that surface will attract daily.

Available only in the 1TB configuration, the limited edition white Steam Deck is not a casual purchase — it is priced above the standard black variant, and that premium is entirely about the colorway rather than any specification difference. Valve has been direct about the potential for further bold color options depending on how this version performs in the market, and the design language of this release suggests they genuinely understand that hardware can carry emotional weight beyond its spec sheet. Their stated commitment to continued software and hardware improvements also changes the calculus on what the purchase represents. You are not buying a device at its peak; you are buying into an object that the people who made it intend to keep improving.

What We Like:

• The off-white and orange colorway is the most considered visual design statement in the handheld gaming category
• 1TB OLED configuration with HDR support represents the best display quality available in a handheld gaming PC

What We Dislike:

• The white shell will show dirt and wear significantly faster than the black variant, demanding frequent cleaning
• Limited edition pricing premium is cosmetic rather than functional, which makes it a harder case to make to practical buyers

4. MSI Claw 8 AI+

MSI’s second attempt at a handheld gaming PC makes a strong case for listening. The original Claw’s 53Wh battery was one of the most discussed disappointments in gaming hardware, and the Claw 8 AI+ responds with an 80Wh unit that matches the ROG Ally X — immediately removing that criticism from the conversation. The redesigned chassis is more comfortable to hold than the original, which sounds like a modest correction but represents the difference between a product you use and one you tolerate through a session. The 8-inch display at 1080p and 120Hz is the screen you can actually picture using across several hours without fatigue, and the overall hardware package reflects a manufacturer that took its first attempt as useful data rather than a finished result.

The dual Thunderbolt ports are the detail that separates the Claw 8 AI+ from most of its direct competition. In a category where connectivity has generally been an afterthought, Thunderbolt transforms the device into something more versatile than a dedicated gaming handheld. It can drive an external display, connect high-speed peripherals, and function as a desktop replacement when docked — a use case that justifies the form factor for people who travel and need their hardware to earn its carry weight across more than one context. MSI’s continued driver support for the original Claw also signals something about the relationship they want to build with buyers, which matters when you are deciding which ecosystem to invest in for the long term.

What We Like:

• 80Wh battery resolves the original Claw’s most criticized weakness, matching the ROG Ally X for endurance
• Dual Thunderbolt ports offer versatility that positions the device beyond pure gaming into broader portable computing

What We Dislike:

• 1080p resolution on an 8-inch screen sits at the market standard rather than pushing the category forward
• The redesigned chassis was not available for hands-on evaluation at launch, leaving the real-world grip feel unconfirmed

5. ADATA XPG Nia

The XPG Nia arrives with a design philosophy that most handheld manufacturers have been too conservative to commit to: repairability as a genuine feature. The use of LPCAMM2 memory modules, which are not soldered to the motherboard, makes this one of the very few handheld gaming PCs where upgrading the RAM is a realistic possibility rather than a route to a voided warranty. The M.2 2230 SSD slot handles storage upgrades in the same way, borrowing the kind of upgrade-friendly architecture that better laptops have offered for years. ADATA, better known for its data storage solutions than gaming hardware, brings exactly the right technical background to a product that treats longevity as a design consideration rather than an inconvenience.

This matters more than it sounds in a category that has normalized the idea of buying new hardware every two years because your existing device can’t be updated. Handheld PCs are essentially miniature laptops running laptop-grade hardware with constrained cooling, which has traditionally meant buyers are locked into the specs they purchase on day one. The XPG Nia pushes back against that assumption. It may not carry the brand recognition of Valve or ASUS, but the decision to make memory and storage user-upgradable in a handheld gaming PC is genuinely forward-thinking hardware design. The category is full of devices optimized for the unboxing moment. The XPG Nia is designed for year three.

What We Like:

• Upgradable RAM via the LPCAMM2 module makes it one of the only handhelds built for long-term ownership
• Upgradable M.2 2230 SSD slot extends the device’s useful lifespan well beyond its launch-day specifications

What We Dislike:

• Real-world ease of RAM upgrades remains unproven, as LPCAMM2 is a relatively new memory format
• ADATA’s identity as a storage brand creates unanswered questions around long-term software support and gaming ecosystem depth

6. GPD Pocket 4

The GPD Pocket 4 does not belong in this list by conventional logic, and that is precisely why it does. There are no joysticks, no D-pad, no face buttons. What it has instead is a compact clamshell form factor built around a full QWERTY keyboard, a small touchpad in the upper right corner designed for right-thumb operation in a two-handed grip, and mouse buttons positioned on the opposing side for the left thumb. The AMD Ryzen AI 9 HX 370 with AMD Radeon 890M graphics, 64GB of RAM, and up to 4TB of upgradable NVMe SSD storage inside this chassis is a genuine statement about what a pocket-sized device can accomplish. It is a handheld PC for the person who refuses to separate productivity from portability.

Where most devices in this roundup are gaming handhelds that can also browse the web, the Pocket 4 is a legitimate laptop replacement that can also play games within certain limits. Content creation, entertainment, productivity, and travel computing are all addressed by hardware that fits in a jacket pocket. The 44.8Wh battery is the honest trade-off — you are carrying a compressed laptop, not an augmented gaming console, and the battery reflects that compromise directly. For the person who travels constantly and wants one device that handles most things well rather than two devices that each do one thing perfectly, the Pocket 4 makes more sense than almost anything else in this roundup. It is the most unusual recommendation here, and the most interesting.

What We Like:

• Full laptop-grade specifications, including up to 64GB RAM and 4TB upgradable storage in a genuinely pocketable form factor
• Functions as a true laptop replacement for content creation and productivity without requiring a second device

What We Dislike:

• No gaming controls confine its gaming capability to keyboard-compatible titles only
• The 44.8Wh battery is significantly smaller than competitors that prioritize gaming endurance over overall portability

7. ZOTAC ZONE

The ZOTAC ZONE wears its Steam Deck influence openly and then raises the conversation. The OLED display puts it in rare company — most handheld gaming PCs are still shipping IPS panels, and the presence of an OLED screen here is not incidental. The PlayStation-style button layout mirrors Valve’s device directly, setting it apart from the Xbox-influenced arrangement that the rest of the Windows handheld market has effectively standardized around. The built-in kickstand is the detail that reveals the ZONE’s genuine design thinking. It is an obvious feature that a surprising number of handheld PCs have decided to leave out, and its presence changes how the device lives in practice — on a plane tray table, a cafe counter, or a hotel room desk, where you’d rather not hold the thing for two hours straight.

The configurable controls are where the ZONE earns its premium positioning. Two-stage adjustable triggers and programmable dials around each joystick represent the most granular control customization available on any handheld gaming PC currently on the market. It runs more recent hardware than the Steam Deck, inside a chassis that clearly understands what it is trying to be. The steep price is a real barrier, and the ZONE will not make sense for every buyer. For the player who has worked through two or three handheld PCs already and knows precisely what they want from their next one — better controls, better display, a stand, and hardware that will not feel dated inside eighteen months — this is the device that was built with them specifically in mind.

What We Like:

• Built-in kickstand and OLED display address two genuine gaps in the Steam Deck’s design, both meaningfully improving day-to-day use
• Two-stage adjustable triggers and programmable joystick dials offer the deepest control customization in the handheld gaming PC category

What We Dislike:

• Premium pricing places the ZONE significantly above most competing devices, narrowing its realistic audience
• Strong visual and layout parallels to the Steam Deck make it a difficult upgrade pitch for buyers already in Valve’s ecosystem

The Category Grows Up

The seven devices above represent a category finally learning to want more from itself. Some of them get there through craft — the AYANEO 3’s considered curves, the ZOTAC ZONE’s OLED display and kickstand, the Steam Deck’s limited edition color story. Others earn their place through a harder kind of honesty: the XPG Nia’s upgradable RAM, the GPD Pocket 4’s refusal to be just one thing, the Claw 8 AI+’s willingness to publicly correct its own mistakes.

What unites all seven is a seriousness about the object itself — a sense that the person holding the device deserves hardware that respects their intelligence, their living space, and the money they are spending. The Fisher-Price era of handheld gaming PCs is not entirely over. But these seven devices are making a strong case for what comes after them.

The post 7 Handheld Gaming PCs That Actually Look Like the Future — Not a Fisher-Price Toy first appeared on Yanko Design.

Most upholstered furniture is essentially furniture under stress. Fabric gets stretched, stapled, pulled taut, and forced into submission over rigid frames. It is, fundamentally, a question of control. Danish designer Lærke Ryom looked at that process and decided to do the opposite. Her debut solo exhibition, Raiments, now open at Innenkreis gallery in central Copenhagen, is built entirely around that single act of refusal.

The collection includes a daybed, a chair, a bench, table lamps, a floor lamp, and wall lamps, all presented in soothing cream and chocolate-brown hues. The palette is calm and considered, which makes sense. These are pieces that ask you to slow down and look closely, because the detail is where the story actually lives.

Designer: Laerke Ryom

The daybed is probably the clearest expression of the concept. Long, low, and dressed in Kvadrat wool with visible quilting stitches running across its surface, it reads more like a made bed than a piece of showroom furniture. The fabric is not pulled over the form but rather allowed to settle onto it, the way a well-cut linen drapes over a body. The powder-coated steel frame beneath does its structural job quietly, without announcing itself.

The bench follows a similar logic. Compact and precise, it carries the same quilted wool surface and the same twill weave edge banding that appears across the collection. That edge band is a detail worth pausing on. Ryom chose it specifically because twill weave is a technique rooted in clothing and home textiles rather than furniture. “It places the upholstery pieces somewhere in between,” she has said, “adding to the feeling of a tailored piece rather than upholstery.” It is a small choice with a large effect on how the finished object feels.

The chair, built on an aluminium frame rather than steel, is the lightest piece structurally, and it shows. It sits with a kind of ease that heavier upholstered chairs rarely manage. The wool covers it without gripping it, and the stitching adds just enough surface interest to reward a second look without demanding one.

The lighting pieces are where the tailoring metaphor gets genuinely interesting. The floor lamp and table lamps, both on powder-coated steel bases, incorporate fabric shades that are constructed the same way as the seating pieces, draped and stitched rather than stretched and glued. The wall lamps, built on stainless steel bases, carry the same approach. Seeing the textile treatment applied to lighting as well as furniture makes the collection feel like a genuine system of thinking rather than a one-off experiment. Ryom is not just applying a technique to a single object type. She is testing a philosophy across an entire interior.

Underlying all of it is a material choice that matters. The Kvadrat wool she selected deliberately lacks visible weaving, which gives the stitching room to become the primary surface detail. The quilting is not decorative in a fussy sense. It is structural and honest, doing exactly what it appears to do, which is hold the fabric in place without adhesives or staples. The result is upholstery that can be disassembled, repaired, and eventually recycled. The clothes metaphor is not just aesthetic. It is practical in the most direct way possible.

Ryom, born in 1995 and working out of The Factory for Art and Design in Copenhagen’s Amager district, has been exploring alternative upholstery techniques for several years. Raiments feels like the point where that exploration becomes a fully formed position. The pieces are not minimal for the sake of it. They are restrained because restraint is what the concept requires. Every choice, from the aluminium chair frame to the stainless steel wall lamp bases to the twill edge banding, is in service of the same idea: that furniture should be dressed, not wrestled.

Whether or not that idea changes how people think about upholstery at large is probably too early to say. But Ryom has made a collection that is hard to look at and then go back to thinking about furniture the old way. That, for a debut solo show, is more than enough. Raiments is on show at Innenkreis, Herluf Trolles Gade 28, Copenhagen, through 23 May.

Mid-range smartphones have been getting very good, very quickly. Most now check the boxes for performance, camera quality, and even design, but the compromises tend to show up later. Software support runs out too soon, water resistance gets downgraded to save costs, or the storage fills up faster than expected. It’s a category where the spec sheet looks promising right up until the parts that actually matter start falling short.

Samsung’s Galaxy A57 5G and Galaxy A37 5G tackle those exact issues. Rather than simply refreshing the hardware, these two phones address the pain points that tend to sour long-term ownership, from shorter software cycles to inadequate protection from the elements. Samsung describes both as the most capable Galaxy A devices yet, and for once, that kind of claim holds up when you look at what’s actually new.

Designer: Samsung

The Galaxy A57 5G leads with a noticeably slimmer build, now at just 6.9mm and 179 grams. A 13% larger vapor chamber helps keep the new Exynos 1680 processor running cool through long gaming sessions or extended recordings. The display also gets slimmer bezels and a bright Super AMOLED+ panel with Vision Booster, so the screen stays readable whether you’re inside at your desk or standing in direct sunlight.

Storage is where the A57 5G makes history for the Galaxy A line. It’s the first A-series phone to offer a 512 GB option, a welcome change for anyone managing a large photo library or shooting high-resolution video regularly. The triple-camera setup, led by a 50 MP main sensor with a 12 MP ultrawide and a 5 MP macro, handles everything from wide-angle landscapes to fine close-up detail.

The Galaxy A37 5G takes a different route to earn its upgrade. Its primary camera now uses a larger 50 MP sensor with support for 10-bit HDR video recording, improving low-light performance and color depth over its predecessor. More significantly, the durability rating jumped from IP67 to IP68, and it now ships with Gorilla Glass Victus+ on both the front and back, which is a notable step up at this price.

Both phones run One UI 8.5 with a broader set of Awesome Intelligence (get it? “AI”?) features. The camera uses AI-based subject and scene recognition to balance skin tones and create cleaner background separation automatically. Circle to Search has also been updated with multi-object recognition, so you can search an outfit, its accessories, and the surrounding backdrop all at once, rather than hunting for each element separately or toggling between searches.

What gives both phones long-term value is Samsung’s commitment to six generations of Android OS updates and six years of security support. Add to that 5,000 mAh batteries and IP68-rated protection across both models, and these are phones clearly meant to outlast the typical mid-range upgrade cycle. The Galaxy A57 5G starts at $549.99 and the Galaxy A37 5G at $449.99 in the US, with availability beginning April 9, 2026.

Movable and resizable Taskbar is confirmed to be making its way to Windows 11 this year. Here's everything you need to know about how it will work!

Intel's eagerly anticipated Core Ultra 250KF Plus desktop CPU, the most affordable of the bunch, is now available to buy in limited quantities. It's a perfect option for value-conscious gamers and creators, and I don't expect stock to last long.

The water coming out of your tap has traveled through infrastructure that, in many American cities, predates the internet by several decades. Municipal treatment plants catch most of what they’re supposed to catch, but aging pipes, PFAS compounds from industrial and agricultural runoff, and lead from corroding plumbing each leave their own signature in what eventually fills your glass. Two people living thirty miles apart can have genuinely different water problems, and the solution that works perfectly in one kitchen may be entirely wrong for the other. Spring tends to be when many families actually act on this, a natural reset point where the habits and home conditions worth changing finally get real attention.

Waterdrop Filter has spent the better part of the last decade building a filtration lineup that treats water quality as a variable, not a constant. Five of their systems are currently on sale on Amazon through March 31st, spanning the full range of how people actually live: renters who can’t drill into cabinets, families running a high-demand kitchen with PFAS and lead on their radar, people who want their minerals preserved, and anyone who wants instant hot filtered water without the plumbing commitment. Each one is built around a different problem, and this guide helps narrow down which one is built around yours.

Waterdrop Filter G3P800 Tankless RO System: The Under-Sink Performer That Stays Out of Sight

For families thinking seriously about what’s actually in their water this spring, the G3P800 is where Waterdrop Filter’s under-sink lineup earns its bestseller status. The concerns driving most of those conversations, PFAS compounds, lead from aging pipes, chlorine byproducts, are precisely what this system addresses. Its 10-stage RO filtration achieves 98% PFOA reduction, 99% PFOS, and over 99% lead, numbers that carry particular weight for households with infants, pregnant women, or elderly members. NSF/ANSI certifications across standards 42, 53, 58, and 372 back those claims with third-party verification. The tankless design reclaims 50 to 70 percent of under-sink cabinet space, and the UV sterilization stage catches bacteria and viruses that even a high-precision RO membrane cannot address alone.

At 800 gallons per day, the G3P800 handles the full rhythm of a busy family kitchen, from drinking water and cooking to coffee and baby formula preparation. A brushed nickel smart faucet displays real-time TDS readings and filter status at a glance, keeping the system legible without demanding attention. The 3:1 pure-to-drain ratio reflects a genuine shift in responsible RO design, producing meaningfully less drain water than older systems. Spring tends to be the moment families finally act on water quality concerns sitting in the back of their minds, and the G3P800 meets that decision with something durable, rigorously certified, and quietly capable of handling daily household demand for years.

Waterdrop Filter X12 RO System: The Flagship That Puts Minerals Back Where They Belong

Where the G3P800 is built for families who want serious filtration at serious capacity, the X12 is for those willing to push further. At 1,200 gallons per day across 11 stages of precision RO filtration, it represents Waterdrop Filter’s most complete answer to the growing list of contaminants giving health-conscious households pause this spring. The PFAS reduction figures here are among the strongest in the lineup, achieving 98.88% PFOA and 98.97% PFOS reduction, alongside a greater than 99.87% lead reduction rate. Certified against NSF/ANSI standards 58 and 372, the X12 carries the kind of third-party verification that families with infants or elderly members look for before trusting a system with daily drinking water and formula preparation.

What genuinely separates the X12 from most flagship RO systems is what it does after filtration. Reverse osmosis at this level of thoroughness strips water down comprehensively, which is where the built-in alkaline mineralization stage earns its place. Calcium and magnesium are reintroduced post-filtration, supporting bone health over time and restoring the balanced, naturally mineral-rich character that makes water taste the way good water should. For families prioritizing both purity and nutritional quality, particularly those with growing children, that combination is difficult to replicate elsewhere. The smart digital faucet handles real-time TDS monitoring and filter life tracking with the same quiet intelligence found across the range. Spring health resets tend to go deeper for some households, and the X12 is designed for exactly that level of commitment.

Waterdrop Filter DLG-P: Serious PFAS Protection Without the Installation Headache

The conversation around PFAS and lead tends to center on high-capacity RO systems, and for good reason. But the reality of how many people actually live, in rentals, in first homes, in apartments where permanent under-sink modifications are off the table, means that access to serious water filtration has historically required commitment that many households simply couldn’t meet. The DLG-P is Waterdrop Filter’s answer to that gap. It installs in around three minutes without specialist tools, routes filtered water through an innovative dual-outlet design serving both a dedicated drinking faucet and the main kitchen tap, and achieves 99.7% PFOA and 99.6% PFOS reduction that rivals systems at considerably higher price points. For renters prioritizing PFAS protection this spring, those numbers reframe what budget-friendly filtration can actually deliver.

The system reduces chlorine, fluoride, sediment, and odors across its filtration stages, covering contaminants that affect daily drinking water quality in the most direct ways. A smart filter life indicator removes guesswork from maintenance, flagging replacement needs before performance drops. Filter cartridge replacement takes around three seconds, keeping upkeep genuinely frictionless for fast-paced households where the water filter is expected to work reliably in the background. The black finish gives it a contemporary presence that holds up in modern kitchen environments, and the compact footprint respects the limited under-sink space that comes with rental kitchens. For those who have looked at the G3P800 or X12 with interest but need a solution that fits a different budget and living situation, the DLG-P covers more ground than its entry price suggests.

Waterdrop Filter TSU: The Case for Filtration That Knows When to Stop

Not every household is starting from the same water quality baseline. In homes where municipal supply is reasonably clean but carrying chlorine taste, sediment, bacteria, and trace heavy metals like lead, deploying a full reverse osmosis system is a longer route than necessary. The TSU operates on that logic. Its 0.01-micron ultrafiltration membrane reduces 99.9% of bacteria, intercepts rust, sediment, fluoride, and heavy metals including lead, while leaving the water’s natural mineral content completely intact. Where the X12 reintroduces calcium and magnesium through a dedicated remineralization stage, the TSU simply never removes them, which for households with acceptable source water is both more efficient and more elegant.

What makes the TSU particularly compelling as a spring upgrade is what it doesn’t require. No electricity, no pump, zero wastewater, running entirely on standard water line pressure with nothing added to the utility bill. The 3-stage tankless system saves 50 to 70 percent of under-sink cabinet space. A brushed nickel dedicated faucet comes included, and the filter lifespan runs up to 24 months, meaning maintenance stays minimal across nearly two years. For busy families where easy installation and low ongoing upkeep matter as much as performance, the zero-waste design also reduces environmental impact and running costs over time. For households that want clean water supporting healthier spring routines without rebuilding their entire under-sink setup, the TSU makes a case that’s difficult to argue with.

Waterdrop Filter C1H: Countertop RO With a Trick Up Its Sleeve

Every system covered in this guide has required going under a sink. The C1H abandons that requirement entirely. It sits on the counter, plugs into a standard outlet, connects to a water source without drilling or permanent modification, and starts delivering six-stage reverse osmosis filtered water with no installation window and no landlord conversation. The 0.0001-micron RO membrane targets the same field of contaminants that motivates most spring filtration upgrades, including PFAS, chlorine, heavy metals, and TDS. The detachable tank design means it moves between a kitchen, an office, or a bedroom without friction, which matters for parents with young children or elderly family members who want safe, filtered water accessible across different rooms rather than anchored to a single tap.

The feature that sharpens the C1H’s appeal for spring routines is instant hot water delivered in three seconds across five adjustable temperature settings. Morning tea, pour-over coffee, baby formula, and quick meal preparation all lose the waiting step that a separate kettle introduces. A Favorite Mode remembers preferred temperature and volume combinations so the same result comes out consistently. Smart touch controls manage everything from volume selection to real-time TDS monitoring and filter life tracking. The 3:1 pure-to-drain ratio and a twelve-month filter lifespan keep both environmental impact and ongoing upkeep to a minimum. For households that have followed this guide and still need a solution on entirely different terms, the C1H closes that gap with confidence.

GitHub Copilot already ruffled feathers when it first arrived given what it was trained on. Now it's going to use your interactions with it to further train the models.

Microsoft pledges to fix Windows 11, but users remain skeptical. Performance promises face a growing trust problem across the community.

A wasp’s design is a lesson in efficiency. It combines a potent stinger with a small, agile frame to create a threat that commands respect far beyond its physical size. Koch Tools Design captured this spirit perfectly with the Kansept Wasp, a folder where compact dimensions and aggressive geometry work in concert. The knife’s upswept Harpoon Wharncliffe tip acts as a visual stinger, while the sub-3-inch length ensures it remains a nimble and unobtrusive carry. This folder embodies a philosophy of calculated capability, proving that a small tool can still project a serious and purposeful presence.

At its core, the Wasp is a button lock folder built from a 2.36-inch 154CM blade and textured G10 handle scales. The Koch Tools collaboration provides the confident stance and deliberate lines, which Kansept executes with a durable gray TiCn blade coating on several models. This finish offers both corrosion resistance and a sharp visual contrast against the vibrant handle options. The button lock itself sits neatly flush with the spine, allowing for a clean profile when closed and delivering a satisfying snap upon deployment. Priced at $75.89, the Wasp targets the intersection where enthusiast-level design becomes accessible to a much broader audience.

Designer: Koch Tools Design

The Harpoon Wharncliffe blade profile delivers exceptional tip control for detail work and piercing tasks. The upswept curve terminates in a fine point that excels at controlled cuts, while the flat cutting edge provides clean slicing performance across its full 2.36-inch length. Aggressive jimping runs along the spine, offering secure thumb purchase during precision work or when applying forward pressure. A tactical swedge grinds down the spine near the tip, reducing drag and sharpening the visual aggression of the blade. The 154CM steel handles daily cutting tasks with reliable edge retention, and the gray TiCn coating hardens the surface against wear while adding a matte finish that reads as tactical rather than decorative.

Button locks remain a standout feature at this price point. Most folders under $80 default to liner locks or frame locks, mechanisms that work fine but lack the tactile satisfaction and mechanical interest of a button system. The Wasp’s button sits recessed into the handle spine, protected from accidental activation while remaining easy to locate by feel. Deployment feels crisp and deliberate, with the blade snapping into lockup with authority. The mechanism adds a layer of fidget-worthiness that liner locks simply can’t match, which matters when a knife spends most of its time sitting in a pocket waiting to be used.

Handle construction splits across multiple G10 variants, each delivering a different personality. The light gray and orange versions feature solid scales with diagonal texturing that provides grip without being abrasive. Yellow and jade colorways introduce skeletonized cutouts that reduce weight and create visual drama through negative space. The handle shape tapers toward the base, aiding retention during use and preventing the knife from feeling blocky despite its compact proportions. Closed length measures just over 3 inches, placing the Wasp comfortably in the keychain-compatible category while still offering enough real estate for a full three-finger grip when deployed.

The Wasp competes directly with knives like the Civivi Elementum and CJRB Feldspar, both of which hover around the same price and size. The button lock and Koch Tools pedigree give it an edge in that comparison, offering mechanical and design credibility that budget folders often lack. For collectors chasing variety, the multiple colorways mean there’s likely a version that fits personal taste without compromising on function.
