Every time you type a prompt into ChatGPT, something happens somewhere far away. Servers spin up. Electricity moves. Carbon gets generated. The whole transaction is so clean and invisible on your end that it might as well not be happening. That’s by design, and it’s worth thinking about. Although with the way we use technology these days, we seldom think about the consequences on our environment.

London-based creative studio Oio wants to change that, starting with a small 3D-printed box and a bright yellow pinwheel. Their project, the Hot Air Factory, is a domestic AI device that processes your questions and requests locally, without connecting to the cloud, and every time it thinks, it physically exhales. Hot air pushes out of the top of the device and spins that cheerful little pinwheel. The harder it thinks, the faster it spins. You’re watching computation happen in real time, which turns out to be a surprisingly powerful thing.

Designer: Oio

The concept is simple: make the invisible visible. We know AI uses energy. We’ve read the headlines. But knowing abstractly that data centers are energy-hungry is different from watching a pinwheel turn every time you ask your AI assistant to summarize something. One is a statistic. The other is a moment of honest accountability.

What makes the Hot Air Factory smart, beyond its obvious design appeal, is how it translates cost into human-readable terms. It doesn’t give you kilowatt-hours because most people have no idea what that means. Instead, it tells you something like “that prompt cost the equivalent of brewing a cup of tea” or “watching Netflix for five minutes.” Suddenly the math becomes personal. Suddenly you start wondering whether you really needed a 500-word AI response to a question you could have Googled.

Oio co-founder Matteo Loglio describes it as “a small, domestic AI that reveals the hidden energy cost behind every prompt.” The factory also lets you dial up or down the level of intelligence it uses. Want a quick answer? Use a lighter model, spend less energy. Need something more complex? Crank it up, and watch that pinwheel work for it. You can even schedule your heavier prompts for the night shift, when energy is cleaner and the grid is quieter. These are design decisions that carry real ethical weight, and they’re baked in with zero condescension.

The playfulness and the seriousness aren’t in conflict here. They’re exactly the point. The Hot Air Factory is built in a Frutiger Aero visual language, all soft curves and clean optimism, the kind of aesthetic that makes you want to put it on a shelf next to your plants. But underneath that approachable exterior is a genuinely complicated machine running open-source large language models on a local GPU. It looks like something a friendly robot would carry. It functions like a small act of protest.

AI companies have very little incentive to make their energy costs legible to users. Invisibility is convenient. It keeps things frictionless. It keeps you prompting without thinking about the bill. A report from the US Department of Energy projected that by 2028, data centers could account for 12% of total electricity consumed in the US. That’s not a small number, and it keeps growing every time we treat AI like it runs on good intentions and cloud magic.

The Hot Air Factory isn’t saying AI is bad. It isn’t demanding you stop using it. What it’s doing is quieter and more persuasive than that. It’s asking you to look. To see. To feel, just a little, what your digital habits cost in the physical world. That’s the argument made not through a lecture or a campaign, but through a yellow pinwheel spinning in your living room.

Design can do that. Sometimes a small, well-made object says more than a policy paper ever could. The Hot Air Factory is currently looking for collaborators to help bring it to a wider audience, still working its way from experiment to something anyone can own. If the goal is conscious computing, the first step might just be this: a tiny box, a spinning fan, and the quiet discomfort of watching a machine breathe.

Most furniture sits in a room without saying much. It fills a corner, does its job, and disappears into the background. Nako Baev’s THE OBJECT 01 is not that kind of furniture. The Amsterdam-based designer set out to build a chair that carries the weight of a spatial statement, something that holds its ground without decoration or apology, and in that specific ambition, the object largely delivers.

THE OBJECT 01 is a 3D-printed lounge chair built from recycled PETG, a plastic more commonly found in water bottles than in furniture workshops. At 20kg, it is lighter than its blocky, slab-heavy proportions suggest, though not exactly something you would reposition on a whim. Its dimensions push it closer in scale to a small architectural fragment than to a typical chair, which is likely the whole point.

Designer: Nako Baev

The construction follows a modular panel system, where each 3D-printed block fits into a sequence designed to cut material waste and keep the overall mass structurally lean. Finished in a cold grey Baev calls “Kyoto Fog,” the chair reads somewhere between concrete and matte stone. In a sparse studio or raw loft, it anchors the space with quiet authority. In a more conventional living room, it would likely dominate in ways not every household would welcome.

What makes THE OBJECT 01 genuinely worth attention is how honestly it exposes its own making. The layer-by-layer texture from the printing process is not hidden or smoothed away; it stays visible across the surface, turning the manufacturing method into part of the visual language. That kind of material honesty is far more common in ceramics or cast concrete than in plastic furniture, and it gives the piece a tactile quality that polished renders simply do not convey.

Baev describes the design as sitting between furniture and sculpture, drawing on minimalist brutalism and a quieter Japanese restraint in equal measure. The emotional reference points are more unusual: the designer cites the atmosphere of Silent Hill and Half-Life, those game environments built from silence and abandoned space, as part of what shaped the object’s mood.

The workflow involved AI assistance across early form studies, structural testing, and design refinement, reducing development time considerably. That footnote is becoming standard across the industry, and it doesn’t add or subtract much here. This process might even become the key to sustainable furniture design, as it can help optimize 3D printing, increase efficiency, and reduce waste in the long run.

Most portable computers are sealed boxes, which is exactly what makes them frustrating for anyone who wants to experiment with electronics. You can run code on a laptop, but try wiring a temperature sensor or an infrared transmitter directly to it, and you’ll realize that consumer hardware was never designed for that kind of access. A maker who goes by PickentCode got tired of that gap and built something to close it.

The CyberPlug 3.0 is the third iteration of a personal cyberdeck project, the earlier two having usability problems that sent PickentCode back to Blender to redesign. The final build packs a Raspberry Pi 4 Model B, a 4-inch IPS touchscreen, a Rii K06 mini keyboard with a built-in touchpad, and a 5,000 mAh USB-C power bank into a 3D-printed hinged body that folds flat for handheld use or props open at a desk-friendly angle.

Designer: PickentCode

What separates this from a standard Raspberry Pi build is the pair of breadboards soldered directly to the GPIO pins, seated inside the case, and accessible through a removable back panel. Connecting a sensor no longer means hunting for a separate breadboard and a tangle of jumper wires. PickentCode plugged in a temperature and humidity sensor and had it reading live data within minutes, then built an infrared setup that records remote control signals and replays them as single-button macros.

The two form factors each have a distinct locking mechanism rather than just flopping into position. In handheld mode, twin magnets pull the two halves together. In desktop mode, a metal ring on the back grabs the MagSafe-style power bank magnetically, holding the whole thing at a stable upright angle. Both the keyboard and the power bank slide out independently, and the deck keeps working on a desk without either of them.

Extensions are where the project gets more interesting. PickentCode added a PWM-controlled external fan that reads CPU temperature and adjusts speed automatically, and a small speaker module that opened the door to YouTube and older games. Doom, Half-Life, and GTA: Vice City all ran on it, better with an external setup in desktop mode, though workable in handheld after some button remapping.

PickentCode frames this plainly as a testbed for learning electronics, not a replacement for a phone or a real computer. The 3D files are free on Printables, so the main cost is filament, time, and the components. For anyone who has ever stared at a sealed laptop wishing they could just plug something into it, that framing is probably the most relatable thing about it.
