A Solo Korean Maker Just Built the Writing Device Your Phone Isn’t

There’s a whole category of people who want to write but can’t quite get there on the devices they already own. The laptop opens, and the browser tab is there. The phone unlocks, and three notifications are already demanding attention. Writing apps exist on every platform, but so does everything else, and that proximity makes sustained focus harder than it should need to be. The answer that the market usually offers is another app, which is the same problem wearing a different hat.

The Micro Journal Rev.6.1 comes at that problem from a different direction entirely. It’s a handmade, clamshell writing device built by a solo maker in South Korea, designed for exactly one purpose: opening the lid and writing. There’s no operating system to navigate, no notifications to dismiss, and no browser to wander into. The device boots instantly and drops you directly into a writing canvas, the way a paper notebook would if notebooks could sync to Google Drive.

Designer: Un Kyu Lee (Background_Ad_1810)

The origin story matters here. The Rev.6 that preceded this model was built in response to a playwright from New York who wanted a device compact enough for cafés and distinctive enough to be proud of. The Rev.6.1 takes that same concept, the same 48-key hot-swappable keyboard and color IPS display, and folds it into a clamshell form that closes flat and slips easily into a bag. Community members who received early units called it a “beautiful final evolution” of the Rev.6 concept, which says something about how iterative this product line actually is.

The keyboard uses Kailh hot-swap sockets compatible with Cherry MX switches, which means you choose the switches that match how you like to type and swap them whenever that preference changes. The 48-key layout ships with two additional hidden layers available for remapping, giving far more input flexibility than the key count alone would suggest. It’s a small but considered detail that treats the physical act of typing as something worth getting right.

Files sync to your personal Google Drive over Wi-Fi, with no subscription fee and no middleman service to depend on. An 18650 rechargeable battery handles power, charging over USB-C, which covers the same standard you’re already carrying everywhere else. The whole device is assembled by hand after each order is placed, which adds a few days to the delivery window but also means each unit comes with a degree of personal investment that mass-produced products rarely carry.

The Rev.6.1 sits in a growing ecosystem of writerDeck devices, which are purpose-built writing machines that the community around them treats more like tools than toys. Compared to polished products like the Freewrite, the Micro Journal is more openly a handcrafted object, with visible maker-culture DNA in its design and ethos. That’s not a limitation; it’s the point, and for anyone who already feels the appeal of a mechanical keyboard or a distraction-free tool, the logic lands fairly quickly.

This Free 3D Lamp Has 300 LEDs and Looks Nothing Like a Printed Object

Decorative lighting has become one of the more satisfying corners of the maker movement. Most off-the-shelf lamp designs don’t bring much that’s genuinely distinctive into a space, and the ones that do tend to cost far more than the task deserves. That’s pushed a growing number of people toward building their own, using 3D printing and open-source lighting firmware to create objects that simply wouldn’t exist any other way.

The Cyber Loop Lamp is the kind of result that tends to stop people mid-scroll. It takes the shape of a vertical wheel, somewhere between a car’s rim and a navigation pin laid flat, and wraps that form in a layered lighting system that creates an infinity-like depth effect. The files are available for free on MakerWorld, and building one is a genuinely demanding project.

Designer: LightCore3D

At approximately 25cm tall, the lamp has enough presence to anchor a desk corner without overwhelming it. The design uses colored filament for the outer shell and clear filament for a transparent inner diffuser layer. That separation between the light source and the outer shell produces the glowing, almost holographic depth that makes the lamp look so unlike anything that came off a 3D printer.

The lighting system draws from nearly 300 individually addressable RGB LEDs, packed into a 2m WS2812B strip running at 144 LEDs per meter. Three distinct zones handle the display: a central funnel, the outer perimeter ring, and roughly a dozen inner spokes. Each zone runs its own color and effect independently, giving the lamp that layered, animated quality that holds attention in a way static ambient lighting usually doesn’t.

Control comes from an ESP32 board running WLED firmware, which lets you map each LED zone to its own effects group and cycle through custom presets. WLED is open-source and widely supported, with a large built-in animation library and enough room to create your own sequences on top. The entire system draws from a 5V, 6A power supply, relatively modest for something delivering this amount of visual output.

Getting there takes real commitment. The model spans 12 print plates with an estimated print time of roughly 35 hours, and that’s before assembly begins. Soldering is required, and components like resistors and capacitors join the LED strip and controller in the electronics stack. The creator is upfront that the assembly process isn’t fully documented, so some steps will require problem-solving on the fly rather than following a defined guide.

That friction is part of what makes the result feel earned. A lamp that takes 35 hours to print and several more to assemble isn’t something you’d put together casually, which means it carries weight as an object in the room beyond what any store-bought light could. It sits at a desk or shelf and reads as something deliberately built for exactly the space it occupies.

The Cyber Loop Lamp lands in that unusual territory between a functional accent light and something closer to a display piece, the kind of object that draws questions from people in a room before they figure out what it even is. The model is free on MakerWorld, and the full bill of materials is available directly from the project page for anyone ready to commit to the build.

This 3D-Printed Macintosh Replica Is Actually a Voice AI Assistant

Smart speakers have become some of the most visually forgettable objects in modern homes. A cylinder, a puck, a fabric-wrapped drum, placed wherever the Wi-Fi is strong and largely invisible once the novelty wears off. They do their jobs well enough, but none of them look like they belong in a collection or on a desk that someone cares about. The hardware has always been purely functional, and the design has always shown it.

Alisher Ashimov approached the idea of a desk-based AI assistant from a completely different direction. Kira, his open-source project, takes its visual cues directly from the original 1984 Macintosh, a machine whose beige monolith silhouette is arguably the most iconic in personal computing history. The result is a voice-activated AI companion that looks more like a cherished collectible than a utility device.

Designer: Alisher Ashimov

The enclosure is 3D printed in a single recommended filament color: Light Khaki matte PLA, the closest approximation of that distinctive Apple beige. Rounded top corners, a recessed front panel, horizontal side vents, and a decorative floppy-drive-style slot below the display all reproduce the original’s proportions at pocket scale, somewhere around 80mm wide. A small four-color badge on the lower front panel adds the final recognizable touch.

Where the original Macintosh showed a desktop environment, Kira shows a face. The 1.5-inch OLED display renders two rectangular eyes and a small dash mouth, animating expressively in response to interaction. The wake word is “Hey, Kira,” and from there, a built-in microphone picks up questions while a 4Ω, 3W speaker delivers spoken answers through the sculpted housing. It handles everyday voice queries the same way any smart assistant does, just with considerably more personality sitting on the shelf.

The electronics are deliberately approachable. The core is a Seeed Studio XIAO ESP32-S3 Sense, a capable and compact microcontroller with built-in Wi-Fi, Bluetooth, and a microphone. The rest of the bill of materials, a speaker, amplifier, SH1107 OLED module, mini breadboard, and jumper wires, are available on Amazon for modest amounts. The 3D-printed enclosure is optimized to print in about three hours across two plates with minimal support material, and an assembly guide walks builders through wiring, assembly, and firmware flashing.

The software carries the same open-ended spirit as the hardware. Voice, language, the assistant’s character, and memory settings are all user-definable, which means Kira isn’t locked into a single personality or a single cloud service. Tinkerers can tune the firmware directly. Ashimov has published the files freely, with no commercial barriers between the design and anyone with a printer and an afternoon to spare.

The objects people choose to keep on their desks tend to say something about them. A tiny Macintosh-shaped AI assistant that you built yourself and tuned to your own preferences says rather a lot. It combines a piece of design history, a genuinely capable voice interface, and an honest invitation to understand exactly how the thing works, all in a form that most people will stop and ask about the moment they see it.

This $172 Raspberry Pi Handheld Doubles as a USB Keyboard

The Raspberry Pi Compute Module has always been more useful as a component than as a standalone board. Stripped of the standard ports that make the full-size Pi easy to reach, the CM5 was designed to disappear into purpose-built hardware, doing exactly what a system needs it to do in exactly the space available. That modularity invites projects, and Pi handheld computers have been a natural expression of it for years. Most of them never quite cross the line from capable experiment to genuinely polished device.

The piBrick Pocket-CM5 is an open-source hardware project that comes significantly closer than most. Built from a custom PCB designed for manufacturing at JLCPCB, a 3D-printed shell, and a parts list that totals around $172, it lands at smartphone proportions, 80mm x 145mm x 19.6mm, with the kind of feature density that makes it credible as a daily carry tool rather than a desk ornament.

Designer: Ahmad Amarullah

The display is a 3.92-inch AMOLED panel running at 1080 × 1240 pixels and 90Hz, with 560 nits of brightness and capacitive multitouch for up to five fingers. A custom Asahi Tempered Glass cover sits over the top, which is the kind of detail that separates a considered design from a prototype that happens to work. Full-size and micro-HDMI outputs mean the same device can drive an external display, when a keyboard and mouse are more useful than a pocket-sized one.

That keyboard is a BBQ20, a compact QWERTY design with an integrated trackpad derived from the BlackBerry layout. Side rotary encoders and five user-programmable buttons extend the input options beyond a standard phone form factor, giving the device a tactile depth that touchscreen-only handhelds don’t have. The battery is a 5,000mAh LiPo, and the USB port set covers both USB 3 and USB 2 in Type-A and Type-C configurations, plus an internal expansion header for add-on modules.

One of the more quietly useful features sits at the intersection of the keyboard and the USB stack. The BBQ20 can operate in USB-HID mode, which means plugging the piBrick into any external computer or server turns its keyboard and trackpad into a fully functional USB input device, independent of the Pi. A sysadmin arriving at a server rack without a spare keyboard doesn’t need to find one; the piBrick already is one. That framing, as a tool for engineers and sysadmins rather than simply a hobbyist novelty, runs through the whole project.

A full Linux desktop runs on the CM5, alongside the system administration and networking tools that tend to be useful in those situations. NVMe SSD support in 2230 or 2242 formats adds storage headroom when the SD card isn’t enough. Stereo speakers, a microphone, and an optional camera module round out a spec sheet that covers more ground than the form factor suggests. The project files, schematics, and build instructions are all available as open source, which means the $172 cost is the floor, not a retail price, and the design itself belongs to anyone who wants to build on it.

DIYer turns tiny GameCube keychain into a fully-functional controller

Controllers come in all shapes and sizes, depending on the gamers’ needs, and most importantly, their holding comfort. Things get really interesting as a lot of big tech companies invest a lot of effort in designing a one-size-fits-all controller, which holds good for long gaming sessions. While most controllers are more or less the same size, there’s always that element of curiosity for accessories that are radically different from the standard proportions.

YouTuber Crux, who’s known for interesting creations with an infusion of gaming, has crafted a mini controller out of pure curiosity. Having got the Backpack Buddies GameCube controller keychain, he asked himself the question – can this be turned into a functional controller? That led to this interesting DIY project that is as intricate as things can get, since the maker is dealing with the super small size of things.

Designer: Crux

We all have keyrings in some form or another, and these cute little accessories evoke the feeling – what if these were functional? The DIYer addresses this curiosity with the functional GameCube controller keychain that looks extremely satisfying as it takes shape. Since he was dealing with very small proportions here, the rotary motor tool does the trick of shaving off the extra bit on the inside of the keychain controller to make space for all the electronics. To put together the intricate joysticks, D-Pad, and other buttons, the DIYer goes down the 3D printing lane. Of course, the button controls and the joysticks had to be mounted on a sturdy base on the inside; that’s why Crux goes for the surface-mount tactile switches.

The DIY progresses with splitting the two controller halves and making up the necessary space to fit the electronics. The ultra-thin enameled wires connect the different components to the Waveshare RP2040-Zero microcontroller board, which is programmed with firmware that makes the cute little keychain gamepad act like a native GameCube controller. The final step involved salvaging the wire and plug from the real controller and attaching it to the output ports. Once everything is in place, it’s time to connect the controller to the port and enjoy some gaming. He demonstrates a session of Fortnite and then moves to Mario Kart Wii. All the inputs work as intended, and you just wish this thing were available to grab right away.

If you manage to check out the complete video till the end, Brux hints at more keychain projects in the future. These include the SNES controller, N64 controller, and 3DS controller, which are absolutely cool. Somehow, if he can manage a wireless keychain controller DIY, that would be sublime.

This $30 Gadget Gives Claude a Face That Reacts to What It’s Doing

AI assistants have mostly lived inside screens, and that’s been fine, until you’re deep in a coding session and Claude is quietly running shell commands, editing files, and hitting tool after tool in the background. Knowing what’s happening without constantly alt-tabbing is harder than it should be, and approving or denying an action while keeping your hands on the keyboard is even harder.

That’s the gap Claude Desktop Buddy was built to fill. Released as an open-source project by Anthropic in April 2026 and built as a prototype by OpenELAB, it turns a small ESP32-based device into a physical companion that sits on your desk and mirrors the activity of the Claude desktop app over Bluetooth Low Energy. It wakes when a Claude Code session starts, idles quietly while Claude works, and gets visibly impatient when a permission prompt is waiting for your attention.

Designer: Anthropic, OpenELAB

The reference hardware is the M5StickC Plus, a pocket-sized board with a 135×240 color display, buttons, a built-in IMU, and a LiPo battery. It costs around $30 and comes pre-supported by the firmware. When Claude Code asks to run a shell command or access a sensitive file, the device lights its screen, buzzes, and shows the prompt. Button A approves. Button B denies. No switching windows, no hunting for the right modal.

Beyond the permission workflow, the device also doubles as a passive status indicator. A full vocabulary of animated states, including idle, busy, attention, celebrate, dizzy, and heart, plays out on the small screen depending on what Claude is doing. Shake the device to make it dizzy, flip it face-down to put it in nap mode, and it’ll power off the screen after 30 seconds to preserve battery. The built-in IMU handles all of this through physical gestures.

Transcript scrollback is another feature that makes more sense once you’ve used it. Rather than breaking focus to check what Claude just said, you can scroll recent messages directly on the device’s display. It keeps the primary workflow uninterrupted in a way that alt-tabbing simply doesn’t. The device pairs once and reconnects automatically whenever both sides are awake, so there’s no daily setup ritual.

Character customization adds a layer of personality that feels unexpectedly considered for what is, technically, a developer tool. You can drag a custom GIF character pack directly onto the Hardware Buddy window, and the device switches to the new character live. The default character, a small frog called Bufo, ships with the firmware.

There’s something genuinely different about having a physical object on your desk that reacts to an AI working in the background. It turns an invisible process into something with a face, a mood, and a pair of buttons that put control back in your hands without disrupting what you were doing.

The Orion PDA Runs on Sunlight and Ignores the Internet by Design

The smartphone has become so dominant in daily life that it’s hard to remember what it felt like to carry a device that did only a handful of things. Every swipe, tap, and notification competes for your attention, turning what was once a communication tool into a cycle of endless distraction. The maker community, however, has quietly been building an alternative.

The Orion PDA is one of the more convincing results of that effort. Built by a YouTuber who goes by MVLab, it’s a compact clamshell computer designed specifically for people who’d rather write, listen, or record than scroll. There’s no internet connection out of the box, no cloud, no algorithms, and no push notifications. What it offers is a deliberately focused pocket machine that strips away the noise.

Designer: MVLab

The design takes its cues from the Sharp Zaurus line of pocket computers popular in the early 2000s, and the resemblance is unmistakable. It folds open to reveal a small screen on top, and a full QWERTY keyboard with rubber dome switches below. Function keys run across the top row, letting you access common actions without digging through any menus. It’s compact enough to fit in a jacket pocket.

That screen is a 3.16-inch Sharp Memory LCD with a resolution of 536×336 pixels, rendered in 1-bit black and white. It might sound like a regression, but the display operates on the same basic principle as E Ink, drawing almost no power between refreshes and staying perfectly legible in direct sunlight. Take it out on a park bench or a café terrace, and it won’t let you down.

The custom operating system is built around doing a few things exceptionally well. You can pull up albums stored on an SD card, play them through an external speaker or headphones, and even record voice notes that go straight to removable storage. A lightweight calendar app handles basic scheduling. There’s also a text-scaling setting and a USB mass-storage mode for moving files to and from a desktop computer.

Powering everything is an STM32U575 microcontroller clocked at up to 160 MHz, an ultra-low-power chip that keeps the device running for long stretches between charges. The lid houses an integrated solar panel, which can supplement the battery enough to keep things topped up with occasional exposure to sunlight. A USB-C port also handles charging, firmware updates, and data transfers. An expansion port leaves room for future community-developed modules.

The Orion PDA also packs in a dedicated digital-to-analog converter for audio playback, putting it above the lo-fi output you’d expect from a device this small. A MEMS microphone handles voice recording with reasonable fidelity. It isn’t trying to replace your dedicated music player or studio recorder, but for capturing quick ideas or dictating notes on a long hike, it does what it needs to. For anyone tired of carrying a device that’s simultaneously a computer, a TV, a game console, and a social distraction, this one might be worth the wait.

This pocket-sized cyberdesk built inside Altoids Tin is a portable workstation for geeks

What do you do with your Altoids tins after devouring the mints? Maybe for keeping your coins, hand it over to your mom for storing the sewing accessories, for keeping handy a first aid, or perhaps keep the watercolor paint for your little niece. DIYer “Exercising Ingenuity,” however, has a very unique use for the aluminium container.

The inventive YouTuber wanted to build a fully functional Cyberdesk inside of the Altoids tin. Sounds bizarre? Surely it is, given the size of the thing. In his video, he asked himself, “That looks like a tiny computer?” It was clear from the outset that the assembly would require the utmost level of detail and sourcing all the hardware inside the tiny housing. While it might not be the most powerful machine you can own, it surely is ultra-portable and quite nice nonetheless.

Designer: Exercising Ingenuity

Normally, Cyberdesks are built inside ammo cans, rugged Pelican cases, or anything that has a boxy form factor. The machines piqued in popularity during the 1980s after the science fiction novel Neuromancer. Altoid tins have all these attributes, just the smaller size makes them a very odd proposition in the Cyberdesk world. That said, he set out anyway on putting together the hardware. For the CPU, he used the Raspberry Pi Zero W he had lying around, and a 2-inch LCD from another unfinished project. The power comes from a 750mAh lithium-ion polymer battery.

The real challenge was to find the tiny mechanical keyboard and fit it inside the small space. According to him, this was the most enjoyable part of the project, even though the video suggests it was a difficult one. It required learning how to construct the diode matrix for configuring the input, along with the assembling and soldering methodology of each of the keys. The final step here involved painting the keys with a white ink pen. Once this bit was taken care of, the DIY headed into the moderate level difficulty (at least for us). The next step was to create a 3D-printed frame to keep all the components inside the tin in place.

Wiring had to be kept to a minimum, and soldering of other components had to be done efficiently, as space was a premium. As a last step to make more room for components like the UPS HAT board and the display, the original hinge was extended with another Altoids tin hinge for a makeshift, slightly bigger replacement. Once all the hardware components were secured properly inside the tin, it was just a matter of running the system using the software. To make the thing look and feel like a vintage desktop computer, the DIYer painted the front panel beige.

Fully working computer the size of a credit card is just 1mm thick

In the past few decades, we’ve moved from computers the size of a room to ones that sit pretty on your desk. Apple Mac mini takes all the praise for being a powerful machine without the bulk. The low-cost single-board Raspberry Pi can be categorized as a mini PC, but all the DIYers pretty well know it can do basic tasks for DIY projects.

A developer wants to hit the sweet spot in the middle, having developed a mini PC the size of a credit card. Developed by GitHub user krauseler, the fully working computer dubbed Muxcard. Unlike other single-board computers, this one factors in the thickness as well, being just 1mm thick at any point on the whole make. For the chassis of this amazingly tiny CPU, the maker uses an old plastic NFC card. Understandably, the micro-computer (as I like to denote the build) is in the prototype stage, and the ultimate goal is to make it more durable and powerful.

Designer: krauseler

At the time of making, the credit card-sized computer packs a RISC-V CPU architecture, and a Wi-Fi-capable microcontroller with 320KB of usable SRAM and 384KB ROM. The next version of the mini PC could feature the ESP32‑S3 or nRF52/53, which are more powerful than the currently installed ESP32‑C3 CPU. The display on this thing is a 1.54-inch 200×200-pixel flex ePaper screen that consumes minimal power, which is vital. There’s an LIS2DW12 accelerometer for motion-sensing applications. The thing is powered by a 1mm thick 30mAh rechargeable LiPo battery, but krauseler plans to swap this one with an even slimmer battery cell in the future.

In the plans is the scope for touch button control configuration, a USB Type-C, and a microSD card slot. Since everything is so exposed right now, it’ll take quite an effort to reinforce Muxcard’s design to make it more practical, even if the DIY community has to consider using this for their projects. According to the maker, the prototype “still feels slightly absurd every time the display updates while holding what basically feels like a normal card.” Pondering over the possible applications that I can think of with the card-sized computer could be smart home controls, security systems, or a potent upgrade to the Raspberry Pi for more flexibility in use case scenarios.

The DIY is already an open source project as the hardware files and firmware are already online for non-commercial use. That means, if you are interested, the option to make further improvements is also there, keeping in mind the project cannot be commercially used without the maker’s consent.

6th-Gen iPod Nano powers triple-display workstation, and it actually works

Move away from the largest computer case mod for a moment and give the 6th-generation iPod Nano a moment of fame again. Before you start thinking what that even means, check out the video above, where a creator from the YouTube channel Will It Work has given the tiny MP3 player a new lease of life with a well-orchestrated triple-display workstation powered entirely by the iPod Nano.

I am writing this on a two-display setup installed on my workstation. But there is no denying the fact that three-display setups are really a craze these days. The setups are not reserved for PC and monitor combos. Even laptops with three screens are keeping up with the trend. This is exactly why the idea of hooking up a tiny iPod Nano to three separate screens really grabbed my attention.

Designer: Will It Work (YT)

The 6th-generation iPod Nano was released in 2010 with a capacitive multitouch screen. It was the last iPod device released by Steve Jobs and was really easy to carry around with its clip-on design. Instead of being carried in the pocket, the device could be clipped to your gear and go where you wanted it to go. Now, the interesting device is put to more use than just playing music.

By connecting the iPod Nano to a 30-pin Apple Keyboard Dock, the DIYer was able to rely on composite video signals from the iPod to three connected Sharp flat screen monitors from the early 2000s. The Keyboard Dock was essentially made for the iPad, but the video shows that it has been tweaked to work with the iPad Nano using a 30-pin spacer adapter. In the video, the creator says he was hopeful that the media controls on the keyboard would be able to control the iPod, but eventually found out that no key on the keyboard actually works with his contraption. It just sits there to finish the workstation setup: the highlight of which of course, is the triple-display connected to the iPod Nano.

While the iPod Nano cannot connect output video and audio directly to the displays (or connected speakers), the creator has used a 3.5mm four-pole jack, which handles audio input and output. With some other adaptors and cables involved, the iPod is hooked to the three Sharp LCD models for visual display as well. A set of Apple Pro speakers has been used for audio output and a stylus interacts with the iPod. Both audio (the music) and video (a picture slideshow) can work simultaneously. Will It Work has been able to establish that in the video.

In addition to playing music and running a slideshow on the three connected LCDs, the iPod Nano-based triple-monitor workstation can also be used to record voice memos. To be able to record memos in podcast-level clarity, the DIYer has hooked up the iPod to a desktop microphone. In the video, he shows how efficiently it can record a voice note and how good the playback quality is.
