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.

This outlandish iPhone 13 concept gives a look at what we wish the next big Apple design could be





iPhone 13 is slated for launch next month. The sad reality is that much of what we expect to see in iPhone 13 is already released through rumors; we can’t help but wish for Apple to do something groundbreaking and shock us! For example, what if Apple could do this!

This concept, courtesy of ConceptsiPhones’ YouTube channel, is a very futuristic idea that, if you have followed Apple’s intent of delivering products, would never see the light of day. But then, creative liberty promotes the thinkers to conceive the impossible and leave the masses bewildered. That is exactly what this new iPhone 13 concept delivers.

The iPhone 13 conceptual design showcases a curved display that wraps around the screen on all four edges. The phone body looks pretty much iPhone 11-ish and compromises the metal frame in iPhone 12 for the flowing display. Interestingly, the concept highlights a very Android Phone-like vertical camera array on the back, comprising a quad camera setup.

The 6.4-inch Full-Edge Display of the phone is basically the highlight of this concept. There is no notch but a 13-inch under-display camera makes its debut, and the physical buttons on the side have been embedded into the overflowing display on both sides. On the left of the conceptual iPhone 13 are the volume rocker and virtual power button, while on the right you get shortcuts to interact with the phone more seamlessly.

iPhone 13, though, is rumored to launch with a triple camera configuration, which at this point feels more realistic in Apple’s favor.

As cool and futuristic as this concept iPhone 13 may look, Apple will not announce anything on these lines in the fall event next month. However, from the features mentioned in the idea, we will see the integration of A15 Bionic chipset and the debut of iOS 15. Other than this, the concept is far-fetched and only pleasing for the eye and little to the analytical mind. After all, how would one comfortably hold this phone?

When the iPhone 13 launches next month, it is expected to arrive in four variants like its predecessor with faster 5G and a design more or less like the iPhone 12. The big difference in appearance is expected to be a sleeker notch, as the in-display fingerprint sensor will also be missing. In addition, the Pro models are expected to be upgraded to 120Hz ProMotion displays while the camera array will remain identically to the iPhone 12 lineup with the LiDAR scanner is likely to make way into all four models! As with every Apple event, September can’t get here fast enough!

Engineer designed and built his own functioning mechanical prosthetic hand and it looks like a steampunk beauty!





It looks like equal parts Iron Man and the Winter Soldier, and it makes really cool whirring and clicking noises too!

Most people look to 2019 with a certain fondness and nostalgia, but the year proved quite difficult for Ian Davis. Not only did he lose 4 of his fingers in a freak workshop accident, but he was also diagnosed with Multiple Myeloma, an aggressive type of cancer. To add figurative salt to his wounds, Davis found out his medical insurance didn’t cover costs for a prosthetic hand because ‘he only lost his fingers and not his entire hand’. Determined not to be shaken by this strange detour life forced him to take, and also empowered by his sheer willpower to keep creating, Davis decided to build a prosthetic of his own.

Relying on his professional knowledge as a mechanical engineer, and taking to 3D printing, Ian embarked on a journey to rebuild his hand and his life. “Being a maker, it was a tough deal,” Ian said as he had to use his hand for everything. Davis even documented the entire process on his YouTube channel through a series of videos that show assemblies, versions, updates, and upgrades. In his latest upgrade, Davis demonstrates the prosthetic’s ability to splay (or spread out) the mechanical fingers… something he says is very rare, if not entirely absent, in commercial prosthetics. The fact that the entire prosthetic limb is engineered from scratch gave Davis the ability to repair and augment his creation, something he wouldn’t be able to do with complex, commercially manufactured prosthetic limbs… especially given America’s strict laws against the “Right To Repair”.

What’s really noteworthy about Davis’ creation is that it’s entirely mechanical and doesn’t rely on electronic components, software, and batteries. In a Reddit thread, he mentions that the mechanical hand has many obvious benefits over an electronic one. For starters, it doesn’t need charging (and conversely never runs out of charge either), but it’s also MUCH faster than electronic limbs. It takes an average of 0.2 seconds to open or close the fist, as opposed to electronic prosthetics that can take 10 times longer. Let’s also state the fairly obvious in that it even looks absolutely INSANE, with the steampunk metal digits and the tiny #15 industrial chain running through them… as well as the whirring and clicking sounds they make as they move.

It’s a relentless process of trial, error, and improvement for Ian Davis. He started working on the concept back in July of 2019, and slowly and surely built new features into his hand to make it better, with the latest addition being the splaying function. Moving forward, Ian also plans to implement an Arduino with a display to gain individual control of the fingers and some servo motors to advance the design.

“My end goal is to get picked up by one of the major prosthetic manufacturers and design hands for them in their R&D department, creating real-world solutions for partial hand amputees. Durable products that you can take to work and actually get jobs done with. Allowing people to get back to their lives, doing things that they loved before the time of their life-changing accidents”, Ian says.

Sony PS5 gets a DIY vintage hardwood case in this video by our favorite Youtuber. Watch the video!

Matt, of DIY Perks is back again with another custom hack that you can build in the comfort of your own home. This time, the handyman YouTuber designs and constructs a wooden case for his new PS5. DIY Perks starts his process off by disassembling the casing of PS5 to keep only the core of the unit. Left with a compact and thin inner structure, the bulkiest aspect of the PS5’s internal workings is the cool and heat sink. Since the core of PS5 cannot remain leveled on a flat surface, DIY Perks evens out the structure with a few hexagonal PCB pillar supports. Then, using long screws, the PS5’s power supply latches and securely fastens on top of the leveled-out inner structure. DIY Perks then takes a sheet of carbon fiber, a tough layer of woven crisscrossing carbon fibers, to form the case’s base plate.

Carved into the base plate, DIY Perks creates holes where the rest of the PS5’s components fit. Next, DIY Perks mounts the system’s fan onto the carbon fiber baseplate, overlaying the fan with a grill to prevent anything from getting caught in the fan’s blades. Divided into two halves, the fan pulls air in through both sides, allowing airflow drawn from the heat sink to exit through the carved hole in the carbon fiber base plate. To direct the airflow from the heatsink to the fan, DIY Perks uses strips of foam, a cue taken from Sony.

With the inner system securely fastened to its new carbon fiber baseplate, DIY Perks begins work on the system’s American walnut wood case. Using a Japanese saw blade, DIY Perks carves angled edges on the walnut wood to create a cubic frame. Before situating and locking the PS5 into place within the wood frame, DIY Perks etches holes for the USB cables to reach their port located inside the wooden frame, on the PS5 system itself. Leaning on the holes he previously carved into the carbon fiber base plate to mount it onto the wooden frame, both pieces easily merge with one another.

With the rear side of the case still exposed, DIY Perks uses a CNC router to carve port slits that work as vents for the system to remain cool. Finally, DIY Perks looks to carbon fiber once more for the case’s lid, where he relies on CNC milling to carve a vent for the fan out of miniature hexagon shapes, marrying them to the walnut frame with matching hexagonal wooden inserts. The refined walnut look of the case is certainly a step away from the original metallic and custom brass casing for the PS5. Understated and sophisticated, the new case from DIY Perks doesn’t demand your attention like the original shiny metallic case, but the rustic elegance of the walnut wood blended with the durability of carbon fiber definitely keeps it.

The combination of walnut hardwood framing and carbon fiber covering gives the custom PS5 case a retro feel.

Without a flat surface, when the PS5 is laid horizontally, it doesn’t fit in entertainment consoles.

DIY Perks began by disassembling his PS5.

The cool and heat sink is the bulkiest part of the gaming system.

In order to level out the inner structure, DIY Perks inserted brass washers with varying heights on both ends of the system.

Matt took to a carbon fiber base layer to form the system’s bottom covering.

Matt inserted a grill for the fan’s opening to permit and promote airflow.

Additionally, he inserted a foam strip to direct the airflow.

Using a saw blade to cut the walnut framing’s sides, Matt created a wooden border for the PS5 case.

Hexagonal port holes help to keep the inner workings of the PS5 cooled down.

This electric guitar is made out of 5,000 coffee beans (And it smells like coffee too)





Bold, strong, intense. You could use those words to describe coffee… you could also use it to describe this electric guitar built by YouTuber and guitar aficionado, Burls Art. Designed as a gift for his friend’s company Copper Coffee, Burls Art’s guitar body is made from a whopping 5,000 roasted coffee beans suspended in epoxy. Modeled in the shape of a Gibson Explorer, the guitar’s body proudly showcases the coffee beans and the unique texture created by grinding their surface smooth. It’s got a beautifully speckled, dark cork-like texture, and even smells like coffee! The fretboard and headstock are built from scratch too, and the entire guitar sports copper accents (for the aesthetics, but also because the company is literally called Copper Coffee), and the Copper Coffee logo is beautifully inlaid into the fretboard. If you check out the end of the video, Burls Art gives the guitar a spin too, and just like a good Macchiato, it gives me goosebumps!

A close-up look at the guitar’s body reveals the coffee-bean texture. If preserved correctly and maintained well, the beans should easily last decades, Burls Art mentioned after doing a bit of research. The guitar’s body doesn’t just encase the coffee beans in an epoxy outer container. You can see how the coffee-bean cross-sections are visible on the entire surface. The casting process resulted in a fair amount of air bubbles which Burls Art filled with copper epoxy before finishing smooth with a sanding machine and buffing with a coat of polish. The result really speaks for itself, doesn’t it?

The guitar’s body is fitted with two double-coil pickups and aged copper knobs and hardware. The fretboard sports the Copper Coffee logo inlaid into the wood, using a mixture of copper-colored epoxy and silica powder. The headstock, on the other hand, has an actual copper sheeting that’s been fused to the wood before being polished and adorned with the Burls Art logo.

The back of the fretboard reveals an incredible striped pattern almost comparable to snakewood. A closer look at the headstock and fretboard reveals the guitar’s finer details.

It’s unclear how much time it took for Burls Art to make the guitar from scratch, but the YouTube video really details the entire process out from scratch. It starts with pouring the 5,000 coffee beans into a cast and topping it off with epoxy. Ince cured, Burls Art cuts out the basic shape using a large jigsaw machine before using different tools to define the guitar’s shape and smoothen its surface. The fretboard and headstock were built entirely from scratch too, along with the electricals being routed through the guitar’s main body. Burls Art mentions that the body has a pretty distinct coffee smell (which would have been masked if he had coated the body entirely with epoxy), and that his studio smelled like coffee all through the construction process! The coffee guitar now proudly hangs at the Copper Coffee head office in Austin Texas.

This DIY desk chair doubles as a doghouse and bed to get those little puppies off your lap!





Simone Giertz, a self-described maker, robotics enthusiast, and non-engineer, has a dog, Scraps who loves to sit on her lap and a desk chair that could be improved because of it. Dogs especially like sitting on top of you when you’re working on less important matters, like your job. Searching up and down Google’s limits, Giertz noticed time and time again that there weren’t any desk chairs on the market designed for people with small dogs whose preferred seated position was located anywhere on their owner’s body. So, in the trailblazing nature of her YouTube channel, she designed her own.

In her uploaded YouTube video, A chair made for needy pets Giertz takes us through the construction of both the chair’s initial prototype and its final form. Using Fusion 360, Giertz created a 3D model of the pet chair. The model features an enclosed crate, the main dog door, footrest, stairs, and roof to also work as Giertz’s seat. Employing CNC milling to construct the chair’s top seat and roof, sidewalls, stairs, and front entryway, Giertz cut vertical ridges along the sidewalls to bend them around the radius of the chair. After mounting the pieces of plywood together to form the prototype’s planned structure, Giertz uses screws to attach them, but the finished prototype saw some improvements.

Giertz turned to CNC milling to construct the chair’s bottom piece, this time formed in two sections to fit onto the CNC bed. On top of the chair’s joined bottom piece, the rest of the CNC-milled pieces of plywood came together. To help Scraps move up and down the chair’s steps with more confidence, Giertz narrowed the distance between the steps and added a railing system to border the chair’s stairs, main seat, and roof.

Increasing the size of the dog house’s main door and solving the trouble that came with bent plywood, Giertz opted for a fuller opening located in the spot where the plywood had to bend around the chair’s radius, leaving less tension in the wood. To see Giertz build the chair from the ground up and paint it a “moldy, vomit color,” as she describes (although I’d like even a moldier seafoam green) – scroll below and be sure to watch the video on Giertz’s YouTube channel!

Using Fusion 360, Giertz created a 3D model.

Using CNC milling, Giertz had her pieces of plywood ready for construction.

To connect the chair’s walls to its base, Giertz relied on peg-and-socket building methods.

Giertz eventually decided on using screws to connect the pieces of the chair together.

To help Scraps feel more comfortable moving up and down the stairs, Giertz thought to add in a railing system.

The final prototype saw improvements for the stairs and built-in railing.

Stepping away from ridge-bent plywood, Giertz increased the size of the chair’s entryway to get rid of some of the tension in the plywood.

Finally, Giertz incorporated a railing for the top of the chair and doghouse roof so that she could comfortably lean back.

The finished product includes the fundamental features from the initial prototype, including stairs and footrest.

To enhance the chair’s overall usability, Giertz integrated pull-out drawers into the stairs.
