Someone Built a Working Synth From Cardboard and Walnut Keys

Posted on by

Most synthesizers look and feel like appliances. They’re plastic boxes mass-produced in factories, efficient and functional but utterly lacking in personality or warmth. Pianos and guitars get to be handcrafted instruments with wood grain and visible joints, while synths are treated like glorified toasters with circuit boards inside. That disconnect between electronic music and tactile craft has always felt like a missed opportunity, especially when you consider how satisfying it is to play a real wooden keyboard.

One maker decided to fix this by building a fully functional synthesizer from scratch, using materials that sound completely impractical. The result is a compact, 34-key synth with a fiberglass-reinforced cardboard body, a steam-bent walnut frame, and individual keys handmade from oak and walnut. It looks like something between a vintage record player and a mid-century hi-fi component, with a turquoise fiberglass shell and warm wooden accents that feel more like furniture than electronics.

Designer: Gabriel Mejia-Estrella

The body starts as folded cardboard panels cut from a template, then gets layered with fiberglass cloth and epoxy until it transforms into a rigid, glossy shell. The process borrows from old automotive techniques where fiberglass shaped custom car bodies in the 1950s, giving the synth a retro-futuristic sheen. Around the perimeter sits a continuous steam-bent walnut strip with oval cutouts that mimic speaker grilles on vintage radios, adding visual warmth and a furniture-like presence.

The keys are where the craft really shows. Black keys are made from laminated walnut offcuts, while white keys are cut from oak for contrast and durability. Each key is individually shaped, drilled for a shared steel rod pivot, beveled to prevent jamming, then coated with fiberglass and sanded up to 3000 grit for a smooth finish. The result looks and feels closer to a piano than a typical plastic keyboard.

Underneath sits a custom flexible printed circuit with interdigitated copper pads and rubber dome switches. When you press a key, the dome collapses and bridges the pads, closing a circuit that a Teensy microcontroller scans continuously. The Teensy sends MIDI messages to a Raspberry Pi running Zynthian, an open-source synth platform packed with engines and presets, all displayed on a small touchscreen.

Of course, using cardboard and steam-bent walnut creates challenges the designer readily admits. Cardboard turned out to be impractical, requiring multiple fiberglass layers and tedious filling. Walnut is notoriously stubborn to bend, needing kerf cuts and boiling water to soften the fibers. The designer suggests foam board or 3D printing as easier alternatives and notes that more precise tools would have made the keys cleaner.

What makes this synth significant is how it challenges the assumption that electronic instruments have to be cold and industrial. By using wood, fiberglass, and visible handwork, it reintroduces warmth and personality into something usually purely functional. It’s less a finished product and more proof that synthesizers can be beautiful, tactile objects worth admiring even when silent.

DIYer builds first 100% solar-powered drone that flies without batteries

Posted on by

It’s not usual for DIYers to step up and experiment with the logic of solar-powered devices as we know it. The ideal generally is to keep it simple. Add solar panels, connect them to a battery system, and power the connected devices. But that’s way too straightforward for Luke Maximo Bell, who runs an eponymous YouTube Channel and already has a Guinness World Record to his credit.

Last year, Luke and his father challenged the record for the fastest drone from Red Bull with their 3D-printed drone. It not only officially surpassed the former’s top speed of 350km/h, but actually bettered it by nearly 50 percent, hitting high speeds of 500km/h (310mph). A record-breaking feat verified by the team at Guinness Book of World Records.

Designer: Luke Maximo Bell

The idea of this new solar-powered drone, based on an X-shaped frame, is not to shatter any records per se, but to experiment with the feasibility of a drone that runs completely on solar power, without any battery attachments. Of course, as you see it, a drone like that would practically have little real-world applications, but it could pave the way for more exploration, certainly. Maybe the kite festival of Jaipur, India, could see ropes tethered to kites mounted with solar panels on them someday.

Jokes apart, Luke as for years had this thought of, what if a drone could fly on solar power alone? And this project is “designed to find that out.” From the video demonstration, the drone looks like nothing more than a flying sheet of solar panels, but it has been successfully tested to fly, which is an achievement.

The idea of the drone is based on two parts, as Luke puts it, the drone itself (comprising antigravity motors residing on 3D printed mounts, propellers, and frame. And the second part being the photovoltaic panels. Both are combined to create this sun-loving drone that keeps airborne as long as the sun shines on it. The 18-inch X-frame of their unique drone is made of carbon fiber tubing, and it features the decisive flight controller installed right at the X intersection of the two frame bars holding the propellers at their ends.

Understandably, the entire contraption has taken Luke hours of jostling through the odds, check out the video above for more details; but he has been able to pull it off. With solar panels and no batteries on board, the drone does take off after a few nervous minutes on 100 percent solar power alone. The flight was a “bit shaky,” Luke says in the video, but it’s “flying,” and the testing was “successful,” he proudly notes.

3D Printed case for Halcyon Elora split mechanical keyboard has magnetic wrist pad attachments

Posted on by

KeyChron brought the world’s first split keyboard that retained the vibe of a regular keyboard to spice up the rather boring accessory, which has seen ergonomic design changes, addition of custom keys, and not much of a design DNA evolution. The idea of a PC split keyboard stems from the notion that it alleviates long-term strain and gives the user more freedom to set up a productive desk layout. The Halycon Elora split keyboard (based on the popular Kria keyboard) has an added row of keys for easier access to numbers and symbols, which all goes well for fast typing. But does this split keyboard take the title for being ergonomically comfortable? Surely not.

That’s the reason why a DIYer decided to create an open-source 3D printable split mechanical keyboard case for the Halycon Elora. With this tweak, the everyday accessory feels more comfortable to work with, especially for long sessions. To take things a step further, the custom design makes sure you have a case to put the keyboard in, literally fitting like a glove.

Designer: Fatih Arslan

The barebone Elora keyboard does look a bit incomplete and could hamper the look of your desk setup. Nor does it provide any support for your wrist, which prompted Fatih to draw inspiration from the Kinesis Wrist Pads to create the perfect split keyboard case for the accessory. After careful planning, he made a prototype that added a 5-degree tilt to the keyboard for better reach, especially for people with small hands. There are customizable top and bottom plates, integrated magnetic wrist pads, and rubber stops for stability and control.

Depending on the user, the case can be attached with a wrist pad or the faceplates, thanks to the optional support for attaching an encoder, touchpad, or display to the Elora keyboard. The new accessory for the split keyboard comes with dual USB-C ports for the left part, and one for the right. Magnetic holes at the bottom base fit the compatible Kinesis leather wrist pads, and the DIYer also created versions that have magnetically snapping top plates for people who prefer a different typing position. There are holes at just the right place to route the cables, which the eager users will appreciate.

Most of all, the custom-designed case makes the mechanical split keyboard sturdier and gives it a more finished look that it lacked earlier.  The accessory comes with 12 top plate designs in total that the maker has put up for download, so that users can 3D print and use right away. Of course, there is the freedom to modify the designs to fit individual needs as well.

DIYer recreates a fully functional version of the iconic Xbox “Big X” prototype

Posted on by

Before releasing the official Xbox console, Microsoft was skeptical whether prospective gamers would be able to keep their software image distinguishable from the new hardware venture. To ensure the inaugural gaming console would be perceived as a standalone product, the company created a prototype that looked radically different from a desktop product. At the 2000 Game Developers Conference, Bill Gates and Seamus Blackley showcased the X-shaped version to build the brand image.

Made from solid aluminum, the prototype weighed 40 pounds and cost nearly $18,000 to manufacture at the time. It was not a functional gaming console and was only created to build the brand perception. The first-ever Xbox came a year after that, and the rest is history. Fast forward to the present day, as one DIYer wants to see if the X-shaped console would be an actual feasible product. The answer is yes, as this functional Xbox prototype-inspired console proves it.

Designer: Tito Perez

Meet Tito Perez of the YouTube channel Macho Nacho Productions, who set out to make the functioning variant of the console prototype. The starting point for him was the reference images of the model taken from the rare one on display in New York. The next step involved building a 3D model of the prototype from the visual reference of every curve, screw hole, and other little details. Thereafter, the finalized file was sent to the PCBWay factory to craft the aluminum model, which cost him around six thousand dollars.

The thing was not as shiny as the original one, so Tito took on the task of polishing it himself to recreate the mirror look. Then he had to figure out a way to fit the hardware components inside the “X” form. The modder chose the original time-correct components and also added new components like HDMI, USB-C power supply, and a large-capacity SSD to the mix. To make this possible, he crafted 3D printed mounts and integrated rails to make use of every inch of space. One hardware component that posed a challenge for him emerged as the power supply unit, which was too big for the rig. For this, he took help from a modder friend who designed a custom USB-C power supply that supplied the needed power while being smaller in form factor.

As a last modification, Tito decided to replace the center jewel with his own modernized version that looks much better than the original, to be honest. It is even more functional since the Xbox logo comes to life, or one can program it to show any custom video file as well. The one-of-a-kind console shell has all the ports and jacks on the rear arranged in a hypnotic layout. Gaming works as intended when connected to the console, and carrying it around is no hassle with the custom-built foam case that houses the Xbox console and the accompanying controllers. Tito wants to showcase his creation in conventions and gaming events, which is downright inviting, and I’m sure the gaming community will love this every bit.

Raspberry Pi E-Ink To-Do Display Disguises as Framed Desk Art

Posted on by

Most productivity tools are designed to grab your attention constantly with pop-up reminders, blinking notifications, and endless browser tabs competing for focus throughout the day. But sometimes, the best way to stay focused is to keep your most important information quietly in view, not fighting for your eyes or demanding immediate action every few minutes. Finding that balance between visibility and distraction remains surprisingly difficult in modern productivity software.

The InkyPi E-Paper Productivity Display is a DIY project that addresses this challenge directly and elegantly with minimal hardware. Built with a Raspberry Pi Zero 2 W and a crisp E-Ink screen, it turns your to-dos, deadlines, and progress into a calm, always-on dashboard that helps you stay organized without the noise. The project is open-source, customizable, and refreshingly simple in its approach to keeping you on track without overwhelming you.

Designer: AKZ Dev

InkyPi’s minimalist design starts with a 7.3-inch or 7.8-inch E-Ink panel from Pimoroni or Waveshare, framed in a simple IKEA picture frame that looks more like a piece of art than a gadget on your desk. The Raspberry Pi Zero 2 W sits discreetly behind the display, keeping the whole setup slim, silent, and consuming minimal power throughout the day. The paper-like display is easy on the eyes and never glows or flickers.

The framed display can be wall-mounted above your desk for easy glances throughout the day or set on a stand for desktop reference during intensive work sessions. The E-Ink screen shows information with the clarity of printed paper, making text and graphics readable from across the room without squinting. The lack of a backlight means it works well in any ambient lighting without causing eye strain during long days.

The open-source InkyPi dashboard runs a growing library of 20 plugins, all managed through a web-based user interface that’s accessible from any device on your network. You can schedule automatic refreshes, rotate through different plugins throughout the day, and customize layouts for your specific workflow. Recent plugin additions include a to-do list, day countdown, GitHub commit graph, year progress bar, and RSS feed reader for staying informed.

Each plugin is designed to give you just enough information to stay on track without overwhelming you with excessive detail or constant updates that break concentration. The to-do list shows three customizable lists with clean formatting, the year progress bar visualizes how much of the year remains for goal planning, and the GitHub graph motivates coding consistency through visual streak tracking. Everything updates automatically on your chosen schedule without requiring manual intervention.

The E-Ink display’s slow refresh rate and lack of backlight mean it’s only updated when necessary, keeping your focus on the task at hand rather than the screen itself pulling attention. The dashboard is intentionally passive, meant for glancing rather than interacting, so you’re never tempted to click, scroll, or dive into rabbit holes when you should be working. The analog feel makes it more like checking a wall calendar or notepad.

All hardware and software files are open-source on GitHub, with active community support and ongoing plugin development from contributors worldwide who continue adding features. For anyone tired of digital noise and constant notifications interrupting deep work, the InkyPi E-Paper Productivity Display offers a reminder that sometimes less screen time is exactly what you need to accomplish more meaningful work throughout your day without burning out.

DIY ultra-wide Steam Deck DS hybrid trades joysticks for a keyboard and trackpad

Posted on by

Although hardly the first of its kind, the Nintendo Switch definitely kicked off a handheld gaming renaissance. Now we have mini PCs letting us play all sorts of games on the go and innumerable projects that try to cobble up together their own handheld console. The latter has given rise to many unconventional designs, though most follow the standard combination of buttons and joysticks found on gaming controllers.

One designer, however, went out of his way to do something different thanks to his dislike of joysticks. The result is a unique and rather curious handheld device that combines the clamshell form factor of the Nintendo DS and the guts of a laptop, and then stretches it wide to a rather unusual degree.

Designer: Marcin Plaza

There are a few things quite unconventional about this ultra-wide Steam Deck Nintendo DS hybrid, not just its super-wide form factor. Actually, that shape was a result of the decision to repurpose the usable motherboard of a broken Lenovo laptop, which happened to be roughly 13 inches wide. But unlike another DIY Steam Deck that did the same with a modular Framework laptop motherboard, the “DS Deck” didn’t go the usual joysticks and buttons layout either.

Since the goal was to ditch the joystick and replace it with a more PC-oriented keyboard and trackpad, a new kind of shell design was needed. Long story short, it required looking for a compatible 12.7-inch screen that happened to also be in an ultra-wide aspect ratio. These restrictions and requirements led to a design that followed the footsteps of the clamshell DS, which made for a rather interesting device.

While time and effort were saved in using the laptop motherboard as-is, more time was spent designing a custom circuit board for the non-standard keyboard and button layout. There was plenty of soldering and assembly involved, not to mention repairs of data cables that were accidentally torn off. Suffice it to say, this is a project very few will be able to follow.

Still, the final result is just as interesting and special. The DS Deck is able to run a full operating system like Windows or Linux because it basically uses the same motherboard and battery as the source laptop. Widescreen compatibility with games is a mixed bag, but one can always run two windows side-by-side thanks to the screen size. The custom design definitely needs a lot of work, as it doesn’t take into account safety and heat management, but the fact that it even works is itself already a commendable accomplishment.

Make your own Steam Deck handheld gaming PC using a modular laptop

Posted on by

Handheld gaming devices are quite the fad these days, especially now that major PC makers have all joined the bandwagon. Although we’re reaching a point where all internal specs are becoming identical, there’s still a variety of designs and features available. Just like laptops, however, these designs are fixed and you can only select from what others have already made.

Embodying the spirit of desktop computers, this latest DIY project enables you to build your own Steam Deck clone, presuming you have the parts and skills to assemble one. Unlike other configurations, however, this isn’t relying on some low-power computer like the Raspberry Pi but instead leans on the power provided by a modular laptop design.

Designer: Beth Le

There is no shortage of mods and projects to build custom handheld PCs, whether for gaming or light computing, but the majority of these use small but under-powered single-board computers or SBCs. These are cheap, easy to cram into small shells, but will hardly be able to play any games outside of retro emulators. The problem is that there isn’t an SBC powerful enough to support that use case.

That’s where the Framework modular laptop comes in. Thanks to its modular design, it is possible to actually purchase the mainboard of such a powerful computer, and the 13-inch variant happens to be an adequate size to stuff inside a 3D-printed gaming handheld shell. Although it doesn’t exactly have gaming-worthy specs, it’s still powerful enough to run some AAA games with low settings.

The Beth Deck, which is the name for this hot new build-it-yourself handheld PC, doesn’t stop there. It also uses a matching Framework 13 battery and many off-the-shelf parts. Everything that can’t be bought can be 3D printed, and the claim is that you barely need to solder anything. You could almost say it’s like playing with LEGO, except with computer parts instead of bricks.

It’s not the perfect handheld design, of course, since the Framework 13 mainboard isn’t designed for that purpose. It does, however, reveal the possibilities available with such a modular component available for as low as $199. It might even inspire other designs that customize not just the appearance but also the controls. After all, if you can easily make a Steam Deck clone, why stop at being just a Steam Deck clone?

DIY foldable desk organizer is made from recycled Campus notebook paper

Posted on by

As a self-confessed hoarder and maximalist, my desk is anything but neat. I collect a lot of stationery and supplies (sometimes more than I need) and so I have a lot of things lying around. There are of course some desk organizers there but the small items can sometimes be just left scattered all over. This new DIY stationery items can help with that problem.

Designers: Erlend Storsul Opdahl/Milla Eveliina Niskakoski for Kokuyo

RAE is a desktop organizer that is made from recycled paper from scraps of Campus notebooks from Kokuyo’s manufacturing factories. Since the strength and abrasion resistance is affected if you fully use the recycled fibers as virgin materials, they decided to make that just 50% of the recycled paper.

What makes this even more interesting is that the user will be the one to “assemble” the organizer by folding the paper, origami-style. There are two sizes of the paper: the S size (W155 x D70 x H30mm) which is a smaller, squarish kind of organizer and the L size (W250 x D70 x H30mm), a more elongated version. You can place various stationery stuff on it, including pens, paper clips, washi tapes, and other small items you may have lying around.

The package, which contains two pieces, comes with an assembly practice sheet but there’s also a video on YouTube if you need more visual instructions. It comes in beige and khaki colors, keeping with the minimalist feel. It would be cute to have some of these paper organizers on my table, if I can actually follow the instructions.

Retro-style handheld computer flaunts QWERTY keyboard and a Raspberry Pi

Posted on by

It’s pretty amazing how much computing power can be crammed into a small space these days. After all, our smartphones are very capable computers themselves, but we also have handheld gaming PCs and single-board computers or SBCs that are no larger than (very thick) credit cards. The latter, popularized by the super-affordable Raspberry Pi, blasted wide open the doors to creative projects and gadgets, from mirrors that act as your smart home console to fictional cyberdeck computers brought to life. This latest design is one of the latter, offering a handheld computer with modern features and an aesthetic that seems to come from an alternate 80s timeline.

Designer: soulscircuit

Despite its size, the Raspberry Pi is a complete computer, one that can run desktop operating systems, including a trimmed-down version of Windows. With just the right peripherals, it can be used as a normal computer, and some have even turned the SBC into a laptop or even a desktop, complete with liquid cooling. These, however, don’t take full advantage of the Raspberry Pi’s small and portable size, a form that’s perfect for a handheld computer.

The Pilet 5 handheld console adds those essential missing parts to the barebones computer, turning it into a finished product that is usable the moment you turn it on. This form takes the shape of a rather chunky box with a 5-inch screen at the top and a QWERTY keyboard on the bottom half. This isn’t the first BlackBerry-like design powered by a Raspberry Pi and it definitely won’t be the last, but there are a few details that makes this project a bit interesting.

In addition to the keyboard, Pilet 5 has a four-direction D-pad as well as a tiny trackball on the right side of the device, while the opposite side has a joystick and a scroll wheel. These would definitely be more than enough to move the mouse, if the touchscreen still wasn’t enough, and they open up more use cases, like gaming for example. The aesthetic of the design is also less grungy and raw, unlike typical cyberpunk-inspired “cyberdecks.” The beige motif, gray buttons, and minimal colors give it a vibe similar to the consoles and computers from the late 80s and early 90s.

Just like the Pilet 7, formerly known as Consolo, the more compact Pilet 5 still promises a 7-hour battery life thanks to dual 8,000mAh batteries, just in a smaller and more complete form. That said, it does lose out on the appeal of a modular design that can adapt to almost any use case, which is what the Pilet 7 will bring to the table once it’s actually out.
