This palm-sized robot dog has a Nokia battery and a customizable LEGO-compatible back

Posted on by

Petoi has been shrinking Boston Dynamics down to desk size for almost a decade now. Dr. Rongzhong Li started the company in his dorm lab in 2016, after a video of his open-source robot cat prototype went viral. That cat became Nybble, a laser-cut wooden kitty, and it was followed by Bittle, a palm-sized robot dog that ended up in classrooms, research labs, and a surprising number of home offices. Petoi says it has shipped more than 30,000 robots to over 60 countries, all running its open-source OpenCat framework. Each new model has gotten smaller, smarter, and easier to build, which brings us to the newest pup in the litter.

Meet Quaddle, a palm-sized robot dog that walks, glides, spins, and does backflips using just four servos. That’s half what Bittle uses in its legs and roughly a third of what most quadrupeds need, thanks to a spring-loaded linkage Petoi calls the MinDoF leg, which lets one motor drive both the shoulder and the knee. It weighs about 6 ounces, snaps together without screws, and takes LEGO bricks on its back. You can teach it tricks by physically moving its legs, chat with it, or code it in anything from beginner blocks to ROS. Prices start at $179, which is pretty reasonable for a dog that never needs walking.

Designer: Petoi

How one servo runs an entire leg

Each of Quaddle’s legs hangs off a single servo, with a spring and a four-bar linkage doing the job a second motor normally would. As the servo swings the upper leg, the linkage folds the knee up and straightens it again, turning one rotating shaft into a proper step. Petoi calls this the MinDoF leg, short for Minimal Degrees of Freedom, a degree of freedom being one independent way a joint can move. The spring clips onto different anchor points, changing how stiff or bouncy each leg feels. In Petoi’s tabletop tests, Quaddle walks about one body length per second, turns 90° in a single step cycle, and climbs onto a ledge as tall as its own knee.

Walking machines driven by a single crank go back to Pafnuty Chebyshev, the Russian mathematician whose 1870s linkage turned rotation into a surprisingly lifelike stride. Theo Jansen’s wind-powered Strandbeests on Dutch beaches run on the same basic idea, and Quaddle feels like their tiny, battery-powered cousin. Petoi added one more trick by fitting small bearings to the tips of the feet. Angle the legs just right and those bearings become wheels, letting Quaddle glide across a smooth desk at around three body lengths per second without a single extra motor. Fewer motors also means less weight, less cost, and less battery drain, which is how the whole dog comes in at roughly 6 ounces.

Teach it tricks by hand, then teach it in code

On the Buddy and Scout models, every leg servo reports its position back to the robot, so you can teach Quaddle a move by simply grabbing its legs. Tap to start recording, guide the legs through whatever silly dance you have in mind, and tap again to have it play the motion back. There’s no app or code involved, and Petoi says you can teach it a basic walk in about ten seconds. Recorded moves can be pulled into Petoi’s Skill Composer software for fine-tuning and shared with other Quaddle owners. For a kid, this is probably the fastest route from “I wonder if” to a robot actually doing the thing.

Buddy and Scout split their thinking across two ESP32-S3 chips, one for motion and balance and one for voice chat and smart home control. A physical slide switch cuts power to the AI chip entirely, which is great for privacy and for days when your robot dog gets a bit too chatty. Coding starts with drag-and-drop blocks, moves to Python or MicroPython, and eventually reaches the Arduino C++ firmware. Bigger projects can mount a Raspberry Pi Zero on its back or plug into ROS, the software framework most research robots run on. A browser-based simulator runs the same code as the real robot, so you can test ideas on a laptop or even a phone with no robot in sight.

LEGO bricks, a Nokia battery, and three Quaddles to pick from

The top of Quaddle’s shell takes LEGO bricks, and Petoi will publish printable shells and mounts for anyone with a 3D printer. Petoi’s own demos have turned it into a walking LEGO AT-AT, a waddling biped called the NanoDuck, and a rover on Mecanum wheels, which use angled rollers to slide sideways. Power comes from a swappable Nokia-format phone battery, the same BL-5C shape that lived inside Nokia’s famously indestructible early-2000s handsets. Quaddle ships with the bigger 1,800 mAh BL-10C cell, good for roughly 1 to 1.5 hours of walking depending on the model. Plug it into USB-C while you code and it charges as it runs, so marathon debugging sessions are fair game.

Builder PLUS ($179) handles walking and coding, Buddy ($219) adds AI chat and teach-by-hand, and Scout ($269) adds a sensor head that detects gestures, light, distance, and people. All three are priced at $144, $175, and $215, with deliveries starting in December. For context, Petoi’s own Bittle X lists at $279, Unitree’s Go2 starts around $1,600, and Sony’s Aibo launched in the US at $2,900. Petoi spent a decade shrinking big robots down to desk size, and Quaddle shows the smartest way to shrink one further is to give it fewer parts.

LEGO shows how you can make a DIY engagement ring box from bricks

Posted on by

Most women (or men) probably prefer to get a traditional diamond (or some jewel) in a box when it comes to engagements. But there are also couples who prefer to do something unique for their marriage proposals and connected to that, get something that is more personal and different than a jewel. Geeky couples in particular probably are looking for something different and tailor fit to their interests and if they’re LEGO enthusiasts, then this would be interesting to them.

Designer: LEGO

A video posted on the LEGO South Africa account shows how you can create your own DIY ring box. It doesn’t seem to be any special, new LEGO set that you will have to purchase in order to make this special box. The man demonstrates how you can use spare bricks to build your own ring box, although you probably have to pause the video a few times as there are no written instructions on how to do it step by step (although there are step-by-step screenshots).

The tutorial walks you through the whole process of constructing a ring box. He even makes a tiny, plastic ring to show that it can fit inside and it will not fall out no matter how many times you shake it. The main colors used in the video are green and yellow but in the end he shows that there are countless customizations that you can do by using different colors and pieces, although you will have to figure it out on your own.

If the couple are both LEGO fans, this will be an interesting way to have a unique proposal. And even if you have an actual diamond or jeweled ring with which to propose, putting it inside a DIY box made from LEGO bricks is pretty sweet.

DIY kit lets you build your own Seiko watch movement from scratch… and it works!

Posted on by

The devices and gear we own today are vastly different from the ones our grandparents owned. Back in the day, products could be pulled apart, tinkered with, and repaired without much of a fuss. Radios lasted decades, toasters from that era still work today, but the devices of today are a little too complicated to repair or tinker with. In fact, the companies that make these devices don’t even want you looking under the hood – try tinkering with a Tesla car and the company can remotely disable your entire vehicle for tampering. Mess with an Apple phone and its warranty gets voided. If you bought a Spotify Car Thing, regardless of your efforts, the company is planning on bricking the device globally at the end of this year.

The reality is that we aren’t intimately familiar with the stuff we own today, and it’s time we changed that. The folks at Rotate Watches believe the only way to change this is to make tinkering more accessible. This beginner-friendly 50+ piece kit lets you build your own working, automatic watch movement from scratch. Modeled on the Seiko NH36, this kit has everything you need to be an amateur horologist. A guide helps take you through the various processes, and at the end, not only do you have a working watch that you can keep on your table to tell the date and time, but you also inherit an innate understanding of how timepieces work… and that’s just priceless, isn’t it?!

Designer: Rotate Watches

The Seiko NH36 is a popular and reliable automatic movement known for its accuracy and durability. With a diameter of 29.36mm and a height of 5.32mm, it’s a compact powerhouse featuring 24 jewels for reduced friction and a smooth operation. This kit includes the movement itself, along with a set of specialized tools to handle the delicate watch parts. Screwdrivers, tweezers, finger cots, and pliers are all included, ensuring you have everything you need to handle the intricate components.

One of the highlights of this kit is the beginner-friendly guide. Rotate, the company behind the kit, understands that watchmaking can be intimidating for newcomers. Their detailed instructions break down the disassembly and assembly process into clear steps, accompanied by numbered pictures for easy reference. The guide goes beyond just the mechanics, explaining the purpose of each piece and offering helpful tips and tricks throughout the process. For those who prefer a greater challenge, Rotate also offers the option to receive the movement disassembled. This allows experienced hobbyists to dive right into the reassembly process, testing their watchmaking skills.

Build your own Patek Philippe-style Chronograph using this DIY Wooden Watchmaking Kit

Posted on by

Not everyone can afford a Breguet, Rolex, Richard Mille, or Audemars Piguet. Not only are they ridiculously expensive, they’re also gatekept from us regular folk by an arduously long waiting and approval process. You don’t simply go buy a Patek Philippe, you need to be ‘approved’ to buy one. This artificial scarcity makes it difficult for any watch enthusiast to appreciate great watchmaking, but the folks at Tèfo Clockwork have a clever solution – their laser-cut DIY kits allow you to build some of the most beautiful movements and complications found on luxury watches. Instead of splurging millions on a timepiece, Tèfo’s DIY kits let you build working mechanisms for a few hundred dollars, turning them into functional table clocks instead.

Designer: Tèfo Clockwork

Created by a team of hardcore horology-enthusiasts, Tèfo Clockwork’s kits bring million-dollar timepieces to the masses. Their laser-cut wooden kits are highly detailed, and are scaled up so you don’t need Swiss-level precision to assemble them. Their current kits come in 4 complication styles – a Center Tourbillon, a Minute Repeater, a Fly-back Chronograph, and a Perpetual Calendar. These complications can be found in some of the most high-end watch brands, but with Tèfo, they can be bought, assembled, and admired at a much lower price. The complications aren’t the watches themselves, so Tèfo isn’t infringing on any intellectual property. The mechanical movements are open for all to build (although some of them like the tourbillon are so complex on a small scale that only a few companies can build them), and that’s pretty much what the Tèfo Clockwork kits hope to achieve.

The center tourbillon

Back in the late 18th century, Swiss-French watchmaker Abraham-Louis Breguet developed the tourbillon, a watch complication that was designed to counteract the effect of gravity on the watch’s accuracy. This was a concern back in the days of the pocket watch, but as wristwatches gained popularity, a fixed direction of gravity wasn’t really a concern because of the wrist’s constant movement. Tourbillons soon began fading away (given how complex they were to manufacture), although some brands retained them as a work of luxurious art and a symbol of craftsmanship. The Tèfo TC-01 table clock scales up the classic tourbillion, which can be visible right behind the TC logo on the front. The entire contraption measures approximately 10 inches tall and wide, featuring a skeletal design of multiple wooden components that assemble together to create the TC-01 table clock. More than 300 parts come together to build the TC-01, taking over 15 hours (think of it as a highly complex 3D puzzle). The clock draws power from a 12V motor, which is designed to run 24/7, and when you’re not admiring the constant movement of the tourbillon inside, you can actually use the TC-01 to read the time thanks to an hour and a minute dial that rotate with the same accuracy you’d expect from a haute Swiss-made timepiece. At the center is the Tèfo Clockwork logo, which rotates precisely once every second.

The minute repeater

You can build on the TC-01 by adding a minute repeater to it. The minute repeater was originally developed to help tell the time in the dark by chiming every hour, quarter, or minute depending on its setting. Originally used by aristocrats in the 1600s, this too disappeared ‘with time’, becoming just a mechanical luxury found on high-end watches. Tèfo Clockwork’s Minute Repeater module comes with more than 400 parts, requiring over 24 hours of work to put together. Once assembled, it can be paired with the TC-01 by plugging into its side and connecting using a series of pins. Similarly, Tèfo is working on two more complications – the fly-back chronograph (found on ultra-premium Richard Mille watches) and the perpetual calendar (which can be found in Patek Philippe’s watches that cost up to 9 million a pop) that can both be plugged into another side of your TC-01 clock, building on its intricacy, complexity, and accuracy. Both the fly-back chronograph and the perpetual calendar come with 150 parts, and take roughly 8 hours to put together.

Tèfo Clockwork’s entire kits come made from precisely laser-cut wood, with a combination of both light and dark woods to help highlight certain features and increase contrast between different parts. Load-bearing components or parts subject to wear-and-tear are made of metal, while ball-bearings ensure gears, hands, and other components like the tourbillon can rotate freely without any sort of friction. The kit is available as a central module that serves as a clock, with the option of plugging two more modules into its left and right sides to create a larger-than-life functioning luxury clock! Who says you need to sell your house, car, and kidney to afford a Richard Mille or an Audemars Piguet complication?!

The Tèfo Clockwork TC-01 starts at $249 for just the center tourbillon clock, or $749 for the tourbillon clock and two more complication modules. Tèfo offers global shipping with all units expected to ship by November, making these kits a perfect DIY project for you, or a Holiday Gift for a watch-loving friend or family member!

The Little Toy is an Eames-inspired Ticket To Some Retro Fun and Creativity

Posted on by

For everyone who loves DIY and spaces, this one’s for you! The Eames Office just pulled off the ultimate nostalgia move by resurrecting The Little Toy, a blast from the past that hasn’t seen the light of day since 1961. Charles and Ray Eames, the dynamic design duo, cooked up this gem in 1952 as a tabletop spin-off of their iconic creation, The Toy. And trust me, it’s not just a reissue; it’s a time-traveling invitation to creativity for both the OG fans and the newbies.

Designer: Eames Office

The Toy was for playing “in,” but The Little Toy is all about playing “with.” It’s like they miniaturized the fun, letting you build tiny sets, tents, and houses to jazz up your toy collection. Unlike its flexible predecessor, The Little Toy uses sturdier cardboard panels. It is a DIY dreamland for kids and grown-ups.

The Eames magic remains intact – freedom to build whatever your creative heart desires. The Little Toy consists of colored cardboard panels that are tougher than ever, replacing the old plastic-coated paper which is also a gesture towards sustainability. And forget the dowel rods; they’ve jazzed up the assembly with wireframes, making it a breeze to dive into the creative process.

Back in the day (1952-1961 to be exact), The Toy was the answer to space issues and a game-changer when paired with other toys. Tigrett Enterprises of Kansas made sure this mini marvel was a hit. It’s a testament to the Eameses’ knack for turning everyday materials into something extraordinary.

Fast forward to now, and The Little Toy is back, sporting a retro price tag of $79. This reissue isn’t just about reliving the good ol’ days; it’s an open invitation to explore prefab architecture and modular magic. With its vibrant panels and snazzy wireframes, you can go wildcrafting toy houses, funky sculptures, or even desktop architectural wonders.

This revived Little Toy isn’t just a relic; it’s your golden ticket to unlocking creativity, just like it did over fifty years ago. The Eames Office has not only resurrected a classic but handed you a chance to embrace that timeless spirit of play and innovation. So, what are you waiting for? Dive into the past and let your creativity run wild!
