This LEGO Claw Machine Uses Just One Motor (And Lots of Genius)

Posted on by

You know that feeling when you’re at an arcade, pumping quarters into a claw machine, convinced that this time you’ll finally snag that plush toy? Well, someone decided to recreate that delightful torture in LEGO form, and if I could, I would probably line up to buy this one.

Brick Builds, a YouTuber with a knack for mechanical marvels, recently shared their fully functional LEGO claw machine, and it’s the kind of project that makes you want to dump out your entire brick collection and start building immediately. Sure, plenty of LEGO enthusiasts have tackled claw machines before, but what sets this one apart is its elegant simplicity paired with surprisingly complex engineering.

Designer: Brick Builds

Here’s the kicker: the entire machine runs on just a single motor. No fancy Mindstorms robotics kits, no Power Functions overload, just one motor and an absolutely ingenious system of gearboxes doing all the heavy lifting. If you’ve ever tried building anything motorized with LEGO, you know how easy it is to throw motors at a problem until it works. But Brick Builds went the opposite direction, creating something that’s mechanically efficient and genuinely impressive to watch in action.

The magic happens through a series of clever gearboxes that control the claw’s movement in multiple directions. You’ve got your horizontal travel, your vertical drop, and of course, the all-important grip function. Getting one motor to orchestrate all of that? That’s the kind of problem-solving that separates casual builders from true LEGO engineers. The scissor mechanism used for the claw itself is particularly neat, giving it that satisfying open-and-close action we all recognize from the arcade versions that constantly disappoint us.

What I love about projects like this is how they blur the line between toy and genuine engineering exercise. LEGO has always been about more than just following instructions and building whatever’s on the box. It’s a creative medium that rewards experimentation and mechanical thinking. When you watch this claw machine in operation, you’re not just seeing plastic bricks move around. You’re witnessing someone who really understands concepts like gear ratios, mechanical advantage, and sequential motion control.

The build also serves as a reminder of why LEGO remains relevant in an age of sophisticated robotics kits and 3D printing. There’s something deeply satisfying about working within constraints. By limiting the design to a single motor and standard LEGO components, Brick Builds essentially gave themselves a puzzle to solve. How do you create complex motion from simple inputs? How do you translate rotational force into the precise movements needed for a claw machine? These aren’t trivial questions, and the answers are all visible in the finished product.

If you’re curious about the nitty-gritty details, Brick Builds included captions in their build video that break down the mechanical systems at play. It’s worth watching even if you’re not planning to build one yourself, because there’s genuine educational value in seeing how all those gears and axles work together. Plus, let’s be real, watching a LEGO claw machine successfully grab and transport a small object is oddly mesmerizing.

This kind of creation also speaks to the vibrant community of adult LEGO fans who’ve elevated brick building into legitimate artistic and engineering territory. MOCs, or “My Own Creations,” have become increasingly sophisticated over the years, with builders sharing techniques, competing in design challenges, and pushing the boundaries of what’s possible with those iconic interlocking bricks.

Whether you’re a longtime LEGO enthusiast, a design nerd who appreciates elegant mechanical solutions, or just someone who enjoys watching cool stuff work, this claw machine deserves your attention. It’s a perfect example of how creativity and technical skill can transform a childhood toy into something genuinely impressive. And unlike the arcade version, this one probably won’t eat your quarters and leave you empty-handed.

This fingertip-sized flashlight pushes rechargeable EDC to its absolute limit

Posted on by

World’s smallest and world’s biggest are two phrases that never fail to grab attention, especially when they’re attached to something as utilitarian as a flashlight. This fingertip-sized rechargeable torch does exactly that, not by chasing gimmicks, but by pushing miniaturization to an almost obsessive extreme. Built as a DIY experiment by YouTube channel Gadget Industry, the flashlight shrinks a fully functional, rechargeable light source into a form factor so small it’s easy to forget it’s even there, until the moment you need it.

At first glance, the scale alone feels unreal. The flashlight can sit comfortably on the tip of a finger, yet it houses a lithium-polymer battery, a charging circuit, a touch-based control system, and a white LED, all sealed into a compact resin shell. It’s a reminder that innovation doesn’t always come from adding more features, but from stripping everything down to what’s essential. In a world crowded with bulky EDC gear promising extreme brightness and endless modes, this micro torch takes the opposite route, prioritizing presence and accessibility over raw power.

Designer: Gadget Industry

The build begins with a tiny 60mAh lithium-polymer battery, chosen specifically for its balance between capacity and size. To make charging possible without inflating the footprint, the maker disassembles a TP4056 USB-C charging board and integrates only the necessary components directly into the layout. A touch sensor replaces a traditional mechanical switch, working through an N-channel MOSFET to control the LED. The result is a simple, intuitive interaction: place your finger over the sensor and the light turns on, remove it and it shuts off. There’s no click, no resistance, and no moving parts to fail over time.

Encasing everything in resin serves both functional and aesthetic purposes. The hardened shell protects the delicate internals from scratches and minor impacts while allowing the flashlight to be shaped and sanded into an organic, pebble-like form. The USB-C port is carefully preserved during the casting process, making recharging as straightforward as plugging it into any modern cable. While the casing offers limited resistance to splashes, it’s clearly not designed for submersion or harsh outdoor abuse, this is a light meant for convenience, not combat.

Performance is modest but respectable given the scale. The LED provides enough illumination for close-range tasks like navigating dark hallways, peeking into tight corners, or serving as an emergency backup when nothing else is available. On a full charge, the flashlight runs for roughly half an hour, depending on the LED used, which feels surprisingly practical for something this small. Compared to commercially available keychain flashlights, there are obvious compromises in brightness and durability, but none of them detracts from the core achievement.

What makes this project compelling isn’t whether it officially qualifies as the world’s smallest rechargeable flashlight, it’s the mindset behind the craft. This build showcases the patience, precision, and restraint required to design at such a tiny scale, proving that even the most familiar objects can be reimagined when size becomes the primary constraint.

This DIY Wooden Battery Charger Brings Dead AAs Back to Life

Posted on by

Most homes accumulate a drawer full of dead AA and AAA batteries, and the uneasy feeling of tossing heavy little cylinders into recycling or the trash. Alkaline cells are marketed as single-use, even though the chemistry can often be coaxed back to life with the right kind of intervention. RegenBox 1 is a small, hands-on challenge to that throwaway logic, turning battery regeneration into a bench-top ritual that requires patience, measurement, and a soldering iron.

RegenBox 1 is a kit that arrives as a flat collection of components, a printed circuit board, electronic parts, and laser-cut wooden panels. Once assembled, it becomes a USB-powered regenerator for AA and AAA alkaline batteries, designed for electronics hobbyists rather than casual users. The wooden case and visible PCB make it feel more like a lab instrument or workshop project than a sealed plastic charger, and building it yourself is half the point.

Designer: Regenbox

Assembly requires a soldering iron and solder, a voltmeter, flat-nose pliers, wire cutters, and a small screwdriver, plus some electronics confidence. The kit supplies the PCB, resistors, diodes, LEDs, IC, battery holders, USB cable, and the wooden enclosure. You are not just buying a gadget, you are learning how it works as you put it together, turning the components into a functional regenerator that can sit on your desk or workbench for years.

Using it starts with testing each alkaline cell with a voltmeter. Below 0.9 V goes to recycling, 0.9 V to 1.35 V is a candidate for regeneration, and 1.35 V to 1.5 V is already reusable. Once cells are slotted in and the USB 5 V input is connected, the circuit feeds very low current for 8 to 24 hours, slowly reversing part of the discharge without stressing the casing or causing leaks.

The boundaries are strict, alkaline only, no lithium, no damaged or leaking cells, correct polarity, and room-temperature use. The red and orange LEDs indicate current flow and help with diagnostics, but the real discipline is in measuring voltages before and after, and respecting the chemistry. It is not a fast charger; it is a patient tool that trades speed for safety and extended second lives.

Getting one or more extra cycles out of batteries that would otherwise be discarded adds up across a household or community. The open, repairable design invites modification and learning, turning energy use into something you can see and tweak. RegenBox 1 becomes a quiet protest against sealed, opaque devices, and a small workshop ally for anyone trying to reduce waste while gaining control over the objects they depend on.

RegenBox 1 changes the way you look at dead alkalines. Instead of being the end of the story, they become candidates for triage, measurement, and careful regeneration. The wooden box on the bench is a reminder that design can intervene not just at the point of purchase, but at the moment we usually give up on an object, asking whether it really needs to be thrown away yet or if a slow, gentle charge might bring it back for another round.

Super Game Boy is a huge handheld that plays classic arcade games

Posted on by

LEGO released a 421-piece life-sized Game Boy replica with Game Pak cartridges but it could not play games. Then later a Aussie modder turned it into a fully functional handheld, and promised that there will be a $50 kit coming in future so that fans can turn theirs into a playable LEGO version. However, the LEGO version has a small screen and you are better off playing titles on the original handheld.

There’s so much craze around the classic Game Boy, you are bound to come across DIYs that spark the attention of arcade gaming community. Chinese YouTuber LCLDIY ventured out on creating his own interpretation of a Game Boy – only that it is much larger in scale. Best of all it plays games sans any glitches and can be carried around like a cool boombox.

Designer: LCLDIY

The DIY starts off by creating a 3D printed shell (using a light curing printer, printing for a week) that houses the 10-inches electroluminescent LCD TV that emulates the warm glow of the original Game Boy. The choice of the display makes sense as the soft glow illuminates the pixels that otherwise would look too harsh on the big display compared to small screen of the Game Boy. Getting the games to run on the rig was not an easy feat as he had to fit in an Intel 845 motherboard for driving the big display and also creating the interface for running the emulated software of the Game Boy handheld console. The classic processor is assisted by the 65540 Flat Panel VGA Controller chip to simplify the clock synchronization and data signals.

BIOS of the graphics card is modified to match the appropriate resolution of the display. The brick-built shell fits into pieces just like an assortment of LEGO pieces and the guts are flush with all the electronic components that make possible the magic. To complete the build, the maker spray paints the shell to replicate the look of the Game Boy. He also makes big tactile buttons and joystick to keep the arcade feel going, and the stickers for labels and the logos are put on the shell. The classic Nintendo gamepad is used to input the in-game actions for games (like Sonic, Yoshi’s Island and Comix) from other platforms like Sega. This is done as big buttons would be impractical and require even more tinkering around of the electronics.

The DIYer is kind enough to make the design files of the shell, PCB files and graphics card BIOS settings available for free for keen DIYers who love the idea of a Super Game Boy. Just seeing him play the classic titles like Contra and Super Mario using those chunky buttons and the joystick is pure joy.

This DIY AI Astronaut Looks Like a Desk Toy Until You Ask It Questions

Posted on by

Most DIY AI gadgets are bare boards and wires, or at best a 3D-printed box, and that clashes with the idea of leaving them on a shelf or side table. Even clever builds end up looking like projects rather than finished objects. D. Creative’s tiny AI robot is a counterexample, a chatbot built inside a toy astronaut that looks like decor first and a smart assistant second, making it actually display-worthy.

The basic concept is a small astronaut figurine that you can talk to, which talks back using a cloud LLM. All the electronics, ESP32-S3, mic, amp, speaker, battery, and OLED, are hidden inside the toy shell, so on a desk it reads as a cute space figure until it lights up and answers a question or starts blinking to show it is listening.

Designer: D. Creative

The internals pack tightly. An ESP32-S3 Super Mini acts as the brain, a digital I²S microphone hears you, a matching I²S amplifier and tiny speaker reply, and a 300 mAh battery with a charging board keeps it running. The 0.96-inch OLED is tucked into the helmet as the robot’s face, giving the AI a place to look back from when you address it or ask for help.

The builder gutted a light-up astronaut toy, drilled a few holes for buttons and a USB port, and then packed the new hardware inside before closing it back up. This is not a 3D-printed shell but an existing object repurposed, which keeps the proportions and charm of the original toy while hiding the complexity and making the result feel less like a gadget and more like a character.

The interaction loop is straightforward. You speak, the mic captures your voice, the ESP32 sends it over Wi-Fi to a speech-to-text service and then to the Qwen3 LLM, the response comes back as text, and a text-to-speech engine turns it into audio for the speaker. The astronaut’s OLED changes expression to show when it is listening, thinking, or ready to answer, turning a text exchange into something more animated.

Putting the same kind of chatbot you might use in a browser into a toy astronaut changes the relationship. The presence of a body, a face, and a fixed spot on your desk makes the assistant feel more like a little character you share space with, and less like a disembodied voice that lives somewhere in the cloud and has no opinion on where it sits.

This project hints at a pattern other makers can borrow, taking familiar objects and quietly giving them new capabilities instead of always starting from scratch. A tiny AI astronaut that fits into a home without looking like a project points toward a future where more of our everyday decor hides small, conversational brains, and where the line between toy and tool gets pleasantly blurry, with AI companions that feel more like friends than appliances waiting for commands.

Tech-savvy YouTuber builds a cardboard airplane with detachable landing gear

Posted on by

The Wright Brothers changed the course of history when they took the first ever flight on December 1903. Their biplane, crafted from wood and fabric, had a rudder for yaw control, wing warping for roll control, and front elevators for pitch control. The first flight lasted for just 12 seconds, driven by the custom 12-horsepower engine and propellers.

The aviation industry has come a long way since that decisive event, and it’s always good to have a similar nostalgic feel again. Peter Sripol, along with his team, has built a cardboard airplane that has plywood-structured wings (just like the Wright Brothers’ airplane) and is capable of flying one person with ease. Interestingly, the DIYer uses a Pizza box to fit in the altimeter, air speed gauge, and the attitude indicator. According to his estimation, the plane is a giant shipping box, given that it has around 95 percent cardboard parts, which in itself is a feat.

Designer: Peter Sripol

The shape of the fully assembled airplane is just like any other double-propeller plane that’s commercially produced. It is narrower on the tail end and wider near the seating section for aerodynamic efficiency. Just that it’s not as polished and fine-tuned since it is just a prototype for now. After putting together the fuselage, wings, and the custom-made wheel assembly that ejects once the thing is airborne to shed extra weight, Peter drove around the plane in taxing mode to check if all the basics are working fine. The wheels seemed to drag a little, and the batteries powering the thing were not enough for the flight speed.

After fixing the initial kinks, he managed to get off the ground a few feet, but as soon as the landing gear assembly detached, the cardboard airplane flew for a few feet and veered off course to land abruptly. Coming back to the design, the corrugated cardboard parts of the plane are glued together for structural integrity. There are small cutouts on the sides and on the front to have a clear view. The DIY project is in work, and the maker plans to install the controls on the sides and the rudder pedals on the floor. For now, Peter uses the wireless controller to actuate the inputs for the drive and flight tests. Fitting the flight controls inside is going to be touch-and-go, given that there is only one entry and exit opening on the plane from the front. The tail section has folded cardboard skins that take the shape of the stabilizers, elevator, and rudder.

The wing is the most challenging section to build, as during flight, cardboard is not the most ideal material due to its low compression tolerance, hence the small plywood plates embedded inside the wing structure. For a secure embodiment, the wings are attached to the fuselage with bolts and reinforced cardboard doublers. The electric motors for propulsion are mounted on the reinforced cardboard structure, while the batteries, speed controls, and the messy wiring are housed inside the fuselage. We’ll have to wait for a few weeks, when the next video arrives, and hopefully Peter will take flight in this DIY cardboard airplane.

Music-reactive LED Christmas tree turns holiday decor into an interactive display

Posted on by

Holiday lighting has long relied on repeated patterns and static effects, but this music-reactive LED Christmas tree brings a new dimension to seasonal decor by turning sound into visual effects. The project is a simple wooden frame with off-the-shelf LEDs and an audio sensor to create a festive display that animates in real time with sound. Built around an ESP32 microcontroller running the open-source WLED software, the assembly combines woodworking, basic electronics, and wireless configuration into a project that is both instructive and visually striking.

The core of this DIY is an ESP32-D1 mini microcontroller, chosen for its built-in Wi-Fi, processing capability, and compatibility with WLED, a flexible lighting control platform. WLED runs on the ESP32 and provides a web-based interface for configuring LED lighting effects, colors, and patterns without requiring deep coding knowledge. In this tree, WLED’s audio-reactive mode analyzes sound input and drives the LED effects so that the lights flash, pulse, and change in response to music playing nearby. A small INMP441 digital microphone module is wired to the ESP32 to capture ambient audio, enabling this interaction between the physical decorations and sound.

Designer: DB Making

Structurally, the tree is made from common materials. A wooden frame cut into the triangular silhouette of a Christmas tree serves as the backbone. Addressable WS2812B LED strips are mounted along this frame, arranged to expose each LED through a round opening in a corresponding ping-pong ball acting as the light diffuser. These balls soften and spread the light emitted by each LED, creating a uniform glow rather than pinpoint beams. A 3D-printed jig assists in cutting consistent openings in the balls, which are then glued in orderly rows to complete the tree’s face.

Electronic assembly happens on a small perfboard, where the ESP32, microphone module, power connector, and LED strip connector are soldered together. Wiring the LEDs to follow the correct data flow direction and securing the controller board in a neat enclosure ensures reliable operation. Once built, a 5V DC supply powers the tree, and the ESP32 is connected to a computer or network to install WLED firmware via the official web installer. Within WLED’s setup interface, users enter Wi-Fi credentials, set the total number of LEDs, assign the correct data pin, and enable audio-reactive settings along with microphone parameters.

After configuration, the tree’s lighting can be controlled from a smartphone or computer, allowing owners to adjust brightness, choose effects, or simply enjoy music-responsive visuals. The sound-reactive mode responds to ambient audio captured by the microphone, translating beats and rhythms into dynamic light patterns that bring an interactive element to holiday decorations.

Beyond its immediate festive appeal, the project provides a learning platform for hobbyists seeking hands-on experience with microcontrollers, programmable lighting, and real-time sensor integration. By using off-the-shelf components and open-source software, builders can expand or modify the design. This can be done by increasing the number of LEDs, experimenting with alternative diffuser materials, or adding networked effects.

This 500-Million-Year-Old Nautilus Shell Is Now a Speaker

Posted on by

The Sazae Radio was a Japanese novelty radio built into a turban shell, sold by lottery in 2016 with just 100 units available for 8,350 applicants. The odds were 83.5 to one. Losing that lottery left a maker named hide-key with a simple choice: accept the disappointment or build something better. The DIY pivot turned into the Steampunk Nautilus, a haptic speaker project that takes a similar idea and pushes it considerably further.

The choice was a nautilus shell, a living fossil that has barely changed in 500 million years. Discovering that its English name matched Jules Verne’s submarine sealed the decision. The goal became not just a speaker, but a piece of audio art with three rules: steampunk-kintsugi repair, where metal celebrates the shell’s imperfections, conservation-minded reversibility, where every adhesive can be removed with acetone, and a haptic drive that turns the shell itself into a vibrating diaphragm.

Designer: hide-key

Early experiments failed. A massive sea snail shell refused to vibrate, too thick and heavy for a small exciter to drive. The nautilus, by contrast, worked immediately. Its thin, lightweight structure, built for buoyancy, behaves like a violin body or speaker cone, with internal ribs adding resonance without mass. The project quietly became a study in bioacoustics, where shell biology dictated whether the fossil could sing, and heavy shells behaved like bricks.

The build starts with a chipped shell and leans into the damage. The broken area is traced, and a 1.2 mm aluminum sheet is hammered and filed to match the organic curve, polished to a mirror, and attached with cyanoacrylate and brass-colored epoxy putty. All adhesives were chosen so they can be removed with acetone, leaving the shell intact underneath. Reversibility was treated as a hard constraint, respecting the specimen while giving it a new function.

The haptic core moved from a boring internal speaker to a vibration exciter mounted in a custom silicone cartridge that fits the shell’s living chamber. Water displacement measured the volume at just 50 cc, and Shore 15A silicone was poured to create a perfect seat. A transparent hair band acts as a hidden pull tab, and a silicone cap hides the exciter and diffuses its faint blue LED into a heartbeat-like glow deep in the spiral.

The base is a Quince burl chosen for its red, white, and black grain that echoes the shell’s pattern. A Magic Circle layout of brass bushings lets the shell’s angle be changed by moving three brass pillars. Threaded brass rods with ball nuts support the shell, and a drop of soft UV resin on each contact point prevents buzzing, making the heavy fossil appear to float while staying mechanically quiet.

Three hidden modes emerge. Holding the shell in your hands for bone-conducted haptic listening, shifting the exciter between internal and external mounts to change the sound from lo-fi radio to a sharper, more direct tone, and the dream of a stereo pair if a second shell appears. The Steampunk Nautilus turns a broken specimen into a reversible, vibrating instrument that asks you to feel the music as much as hear it, turning disappointment from a lottery into something tactile, strange, and surprisingly beautiful.
