DIY the NASA-inspired airless bike tires using PVC pipes, bolts and nuts. Watch the video!

Popular DIY and science YouTube channel, The Q took his viewers through the process of replacing his bicycle’s traditional rubber tires with a set of airless ones put together with an old PVC pipe and some nuts and bolts.

We’ve seen airless tires on construction vehicles, like backhoes and skid steers, and smaller vehicles like golf carts and lawnmowers. No one wants a flat tire while mowing the lawn or playing golf and the chance for a flat tire is far higher in places like construction zones and building demolition sites. It makes sense that some vehicles prioritize airless tires and some don’t, but what about bicycles?

The Q, popular science and DIY YouTube channel, asked the same question and looked no further than an old PVC pipe and some nuts and bolts to answer it. Before constructing his airless tires, The Q was sure to pick a PVC pipe that had enough density to support a rider and ride well on different terrain. Settling on a ½” thick PVC pipe, The Q then sliced the PVC pipe into two-inch wide rings. From there, the DIY YouTuber connected all of the rings into a single link after drilling three holes into each and joining them together with nuts and bolts.

The Q then drilled corresponding holes into the rim of the bike, linking those holes with the ones previously drilled into the PVC rings. Reinforcing that layering with nuts and bolts, The Q repeated the process for two more rows, resulting in a triple overlay of PVC rings. With the main job complete, The Q finalized the project by carving the top layer of rubber from the bike’s original tire before laying it over the rows of PVC rings and gorilla gluing all of the pieces together. From there, the airless tires were ready to hit the road.

While The Q admits that the overall construction could benefit from slight modifications, the bike’s airless tires are fully functional and can ride smoothly over varying terrains, from sand to grass, and from pavement to gravel.

Bosnian man builds a spinning home for his wife that can complete a full rotation in only 22 seconds!

In the town of Srbac, Bosnia, a 72-year-old man transformed his family home into a rotating duplex for his son, daughter-in-law, and beloved wife.

We do what we can for the ones we love. Some might surprise their partner with a romantic holiday, let a friend borrow their car, or cover the tab at a boozy brunch. In Bosnia, a 72-year-old man named Vojin Kusic built a rotating home for his wife, ljubica, following her wish for both their bedroom and living room to face the sun. Some of us do what we can, and then some.

From inside their rotating home, the couple is gently woken up by the sun over fertile grasslands in the morning. Then, come high afternoon while sitting in the living room, the Kusic’s are warmed by natural sunlight and positioned in the ideal spot to keep an eye on who’s coming to visit them. Borrowing electric motors and wheels from an old military transport vehicle, Vojin Kusic built the rotating home with his own two hands.

When Vojin built his family’s first home, he oriented it so that his and his wife’s bedroom faced the sun, but as the years went by, the Vusics realized their need to supervise the driveway from their living room. This realization gave way to their spinning house. Spinning on a 7-meter axis, at its slowest speed, Vojin’s home completes a rotation in 24 hours and at its fastest, the home can turn around in 22 seconds.

Remodeling their family home served more than the purpose of fulfilling ljubica’s wish, as Vojin transformed the home’s topmost level into a loft for his son and wife to live, while the downstairs remained reserved for the parents. While the renovation required a lot of manual labor and electrical rewiring, the rotating feature was inspired and designed all by Vojin’s natural wit.

This sustainable material made from shell waste is cheaper & eco-friendly alternative to concrete!





Each year over 7 million tons of seashells are thrown away by the seafood industry into landfills. Shells are not biodegradable and have a very high disposal cost which harms the environment as well as the restaurant owners. So this innovative, women-run,  material lab called Newtab-22 created Sea Stone – a natural product made from seashell waste that was salvaged from the seafood and aquaculture industries. It is a sustainable alternative to using concrete – one of the biggest producers of carbon emissions – in the making of smaller products.

Sea Stone is made by grinding down shells that are destined for landfills before combining them with natural, non-toxic binders. This grants the material a terrazzo-like aesthetic. The aim is to make it a sustainable alternative to concrete in the design of small-scale products, as the two materials share similar properties. Seashells are rich in calcium carbonate aka limestone, which is used to make cement – a key ingredient of concrete.

The process involves grinding down the shells and mixing them with natural binders. They are then added to a mould and left to solidify into concrete-like tiles. This method is currently carried out manually to avoid the use of heat, electricity and chemical treatments and ensure the process is as sustainable and affordable as possible. It results in variations in the sizes, textures and colours of the shell fragments and means that each piece of Sea Stone is unique. You can get different textures by altering the number of shells, binders, or adding coloured dyes for aesthetics.

“Even though some of the seashells have been recycled and used as fertilisers, the majority of them are being thrown into landfills or by the seaside. The discarded seashells, which are uncleaned or rotten, have not been cleared away at all and they have been piling up near the beach for a long time, thus causing odour pollution and polluting the surrounding land in the long run. Sea Stone proposes the use of discarded seashells to create environmentally and economically sustainable material rather than contributing to the world’s rubbish problem,” explained Newtab-22.

Newtab-22 has experimented with an array of natural binders in the development of Sea Stone, including sugar and agar. It is now reliant on two undisclosed and patent-pending sources. The material is currently being developed for commercial purposes and has so far been used to make products such as decorative tiles, tabletops, plinths and vases.

While the properties of the concrete and Sea Stone are similar, to truly replicate the strength of traditional concrete required in large-scale projects like buildings, an energy-intensive heating process would be required. This would be comparable to the method used to make cement, which accounts for half of all the CO2 emissions that result from using concrete. “The power of the material is different, we do not want to harm the environment in the process or the outcome,” said Hyein Choi, co-founder of the studio.

Sea Stone is versatile, durable and a lightweight alternative to not only concrete but also plastic – it can be used to produce several objects while repurposing waste, reducing carbon emissions of the toxic counterpart materials and keeping the costs low. Time to find that girl who sells sea shells by the sea shore, eh?

The viral Xiaomi robotic dog posed to be an affordable challenge to Boston Dynamic’s Spot just released new images + sketches!

Quadruped robots hit the scene in 1976 and since then, they’ve been used for everything from unsafe forensic and governmental tasks such as bomb-sniffing and mine surveying to clinical tasks like connecting with patients to provide remote medical attention.

Quadruped technology is the talk of the robotics world. Four-legged robots are relied on by industries across the world for tasks that require a stable walking gait and agile mobility. Xiaomi, a Chinese tech company, recently unveiled more 3D renders of their own Quadruped robotic creation, CyberDog.

Currently, the bio-inspired, four-legged robot has been engineered as a robotic companion whose future technical capabilities are still in development. In a recent press release from Xiaomi, it’s said that CyberDog comes complete with “AI interactive cameras [and sensors], binocular ultra-wide-angle fisheye cameras, and Intel ® RealSense™ D450 Depth module, and can be trained with its computer vision algorithm.”

CyberDog’s external interface features an array of camera sensors. CyberDog’s involved vision sensor system allows the robot to carve out its own navigational map and analyze its surrounding environment in real-time, allowing it to look toward a destination and avoid physical barriers on the way. Currently, CyberDog’s integrated software allows the quadruped robotic companion to operate like a real dog.

Inspired by the pet-like nature of canines, CyberDog also features built-in smart technology that allows posture and facial recognition, which means CyberDog can even follow its owner around like a real dog. Xiaomi filled CyberDog with 11 high-precision sensors that allow the robot to register, analyze, and interact with its surrounding environment. With a maximum torque output and rotation speed up to 32N·m/220Rpm, CyberDog can move at speeds up to 3.2 m/s.

Syberdog also comes with 3 type-C ports and 1 HDMI port so users can attach hardware add-ons, Xiaomi describes, “be it a search light, panoramic camera, motion camera, LiDAR, or more.” In addition to its integrated biometric technology, CyberDog responds to voice commands like assigning tasks or operation control. Alternatively, users can manage CyberDog’s movement and direction via accompanying remote control or smartphone applications.

Expanding on CyberDog’s technical and managerial potential, a “rich external interface” includes 3 type-C ports and 1 HDMI port, allowing users to attach hardware add-ons or software systems to make acute improvements to CyberDog’s existing technology. On CyberDog’s ability to register commands, Xiaomi notes, “CyberDog can be called on for the most unique tasks, and the ways in which it can be interacted with holds unforetold possibilities.”

Designer: Xiaomi

Rubber bottomed feet allow CyberDog to move around rugged terrain and indoor settings alike.

Hinged limbs allow CyberDog to move just like a canine animal.

CyberDog can even do push-ups. Only half-kidding. It can do push-ups, thanks to its 220 rpm32N-m maximum torque.

Soft rubber bottoms allow for soft and nimble treading.

11 high-precision sensors fill out CyberDog’s internal wiring that give CyberDog the power to understand, analyze, and interact with its environment.

CyberDog comes equipped with voice command technology and facial recognition software so it can follow humans around and respond to tasks like a real canine might.

CyberDog can conduct high-speed movements up to 3.2 m/s.

This autonomous delivery robot comes with its own little trailer to deliver the bigger parcels!

The age of Amazon Prime same-day delivery and Instacart grocery shopping has turned instant gratification into an expectation. For better or worse, modern delivery services have redefined priority mail, bringing goods to our doorsteps the same day we put in the order. As delivery operators streamline their services, designers are thinking up automated delivery bots to do the magic for us. Oliver, an autonomous and mobile goods courier, is one such bot, developed by Seoul-based designer Taeuk Ham.

Oliver is a collaborative robot that can operate both automated and manual delivery services. Smart technology equips Oliver with the know-how to handle autonomous delivery outings most likely contained within indoor spaces like warehouses and office buildings. Goods can be placed inside of Oliver the same way items are carried by utility carts and additional packages can be attached to Oliver’s rear trailer. Once the goods are packed away, a touchscreen display allows users to orient Oliver and schedule their deliveries. The vertical carrying space automatically rises at each delivery destination to make the unloading process more manageable. Besides automated delivery services, Oliver can operate as a conventional utility cart if users would prefer to deliver their goods on foot.

Even outside of Amazon’s speedy delivery services, workers in offices and warehouses depend on quick deliveries even between floors and adjacent buildings. While Oliver might be limited to indoor settings, an autonomous delivery robot would streamline deliveries during the workday so that workers don’t have to waste any time walking from one office to the next with goods in tow.

Designer: Taeuk Ham

Items can be placed inside Oliver’s frontal cargo space while rear trailers provide additional space for carrying goods.

Deliveries can be programmed on Oliver’s touchscreen panel.

Rear trailers provide additional space for users to place their goods.

Oliver can be used on automatic settings or manually via its steel handlebar.

Oliver is a three-wheeled autonomous delivery robot.

World’s first 3D-printed stainless steel bridge links Amsterdam’s past and future in its red-light district!

Amsterdam is known for its calm canals and winding alleyways, its rich cultural history, and its affinity for all kinds of pleasure. Historical landmarks still charm tourists and residents alike between the city’s canals, while contemporary and sustainable architecture put the burgeoning Amsterdam-Noord borough back on the map. Linking Amsterdam’s past with its future, designers and engineers at MX3D and Joris Laarman Lab developed the world’s first 3D printed bridge over one of Amsterdam’s oldest canals in De Wallen, the city’s red-light district.

MX3D and Joris Laarman Lab collaborated with global engineering firm Arup along with a host of designers and 3D-print teams to develop the robot-welded bridge. Welding traditional steelwork with computational design, the stainless steel bridge symbolizes a linking of Amsterdam’s past with its future. Stretching just over twelve meters in length, MX3D equipped simple, technical robots with purpose-built tools that were controlled by integrated software that the team of designers developed over the span of two years.

Arup, the project’s lead structural engineer, practiced ​​advanced parametric design modeling to streamline the bridge’s preliminary design process. Describing the developmental stages and inspiration behind building the bridge, MX3D notes, “The unique approach allows us to 3D print strong, complex and graceful structures out of metal. The goal of the MX3D Bridge project is to showcase the potential applications of our multi-axis 3D printing technology.”

Currently open to the public, the bridge was unveiled by Her Majesty Queen Máxima of the Netherlands. Ushering in a strengthened bond between the possibilities of modern technology and a reverence for the city’s architectural integrity, the new bridge in Amsterdam’s red-light district stands as a link between the past and the future.

Designers: MX3D, Joris Laarman Lab, & Arup

Using advanced parametric design modeling to streamline the bridge’s initial design process, engineers programmed software to control the 3D printer’s construction and direction.

Amsterdam’s 3D printed bridge merges classical architecture with modern technology.

Constructed offsite, the bridge was transported on a boat to its final destination.

Weaving through Amsterdam’s canals, the bridge was ultimately brought to its final destination in the red-light district.

Her Majesty Queen Máxima of the Netherlands unveiled the project’s debut in ode to Amsterdam’s rich cultural history.

These roller skates for knees might be the most pain-free hack to help finish your home DIY projects!





When working around the house, our knees can really take a beating. Whether we’re uncoiling a plumber’s snake down the shower drain or renovating our kitchen’s tiled floor, we’re usually on our knees to get it done, and by the third or fourth unsuccessful attempt at unclogging the drain, they’re tired. Knees pads help to an extent, but keeping a leveled hand placement above the drain or kitchen floor is key for a precise job. That’s why products like KneeBlades and knee creepers exist – they’re knee pads with wheels to get the job done without sacrificing our knees in the process.

KneeBlades are shaped like kneecap-sized turtle shells with attached wheeled dollies, transforming the knee pads into ones that help move your reach along with each home project. KneeBlades streamline home renovation projects like replacing floor tiles by maintaining your contact with the floor while allowing you to slide along as the project progresses. The dollies on KneeBlades can also be removed to use as regular knee pads. Then, for a more fixed design, knee creepers are shaped more like traditional rectangular dollies with knee-specific dips that are lined with silicone for a soft landing. Knee creepers also come with small sinks where tools and hardware accessories can be stored while getting the job done, setting them apart from KneeBlades.

While KneeBlades offer a more flexible range of motion than fixed-wheeled knee pads, for some they might have too free a range of motion, turning renovation projects into accidental acrobatic routines. The better of the different wheeled knee pads available really boils down to how your body moves. While the free range of motion from KneeBlades allows for a wider reach, your knees could go willy-nilly if you’re not careful enough. Then, the fixed nature of knee creepers allows for more precise work but might hinder the far reach KneeBlades allow.

Illegal LEGO designs that will simultaneously annoy and inspire all the master builders!

LEGO is on a mission. Collaborating with brands across the world, LEGO is rapidly turning into a leader that is making waves – be it celebrating pride month or launching an Adidas special edition brick sneaker, or bringing your favorite FRIENDS moments to life, there is a LEGO set out there for everyone. That is, until we met the Illegal LEGO collection by Matteo Ercole.

This Illegal LEGO collection may be the piece a master builder needs to unleash their creativity. Each piece is a statement in contradictions, with half a raised side and the other a receiver/negative half, making it almost impossible to join your pieces. Or is it? As far as master builders go, they are always looking for complicated pieces that can help them build the next big impossible structure. While the bricks look simple on paper, the trouble comes with mass production is with LEGO’s manufacturing process that uses induction moulding. Usually, the bricks begin with tiny plastic grains called granules which come in a bunch of different colors. The plastic granules are fed down using pipes to the molding machines. Inside the molding machines, the granules are superheated to a temperature of about 450 degrees Fahrenheit (230°C). This melted plastic goo is fed into molds, little metal containers shaped like hollow LEGO bricks, and are cooled and ejected, which only takes about 10 seconds. The process is fast, a need of mass manufacturing. But to create a brick as we described, it would require us to 3D print these bricks individually, which may not suit or give the exact precision injection moulding delivers.

While it may take some time before LEGO actually manufactures such bricks, I know the true enthusiasts will go to every means necessary, including 3D printing the design to bring their next design to life. Do you think LEGO should make these bricks?

Sony debuts original sustainable packaging as part of its initiative to achieve a zero environmental footprint by 2050!

Brands across the globe have taken green initiatives to communicate to consumers their commitment to sustainability. While some companies are rolling out products with longer life cycles that reduce waste and overall consumption, other brands are seeking out sustainable building materials for their products and their packaging. Multinational conglomerate Sony has commenced its own sustainability effort by sourcing recycled paper goods and building material from locally grown annuals to replace their previous packaging, which came from mature perennial trees.

Sony’s Original Blended Material, the brand’s new sustainable packaging, consists of 100% paper material derived from bamboo, sugarcane, and post-consumer recycled paper. Whereas most paper packaging comes from mature perennial trees, Sony’s new Original Blended Material is responsibly harvested from annuals like bamboo and sugarcane, generating less CO2 in the process. Annuals, like bamboo, carry CO2 absorption and emission cycles that last only for one year, decreasing the perennials’ emission cycles that can last several decades by more than half. Similarly, the release of CO2 gas emissions given off from sugarcane fiber production for power generation is halted by using the fiber as one of Sony’s Blended Materials. While the bamboo and sugarcane fiber is both sustainably grown and harvested in local farms, Sony also cuts back on shipping and handling by incorporating post-consumer recycled paper goods into the Blended Material, giving packages a crisp, organic look.

Currently, Sony has developed the Blended Material specifically for their new WF-1000XM4 headphones, but future variations of the organic packaging accommodate differently shaped products by adjusting the construction formula. In addition to acquiring sustainably sourced building materials and cutting back on the effects of shipping and handling, Sony’s Original Blended Material ditches ink for embossed signatures and supplemental package coloring for a more organic look.

Designer: Sony

By adjusting the construction formula, Sony’s new Original Blended Material can be made to fit differently shaped and sized products.

Sony ditches ink for embossing their signature.

Without coloring, Sony’s Original Blended Material achieves an organic look.

Constructed for their new WF-1000XM4 headphones, Sony’s Original Blended Material echoes Sony’s initiative to eliminate plastic packaging from newly designed small products, an initiative set for their medium-term environmental target for ‘green management’ by 2025.
