DIY Airless Tires
Two automotive enthusiasts have been seeing airless tires for years, but only in concept form. So, they decided to take things into their own hands by making their own using PVC drainpipes and tire treads. More specifically, they used a 14-inch steel wheel sourced from an old Mondeo before placing 15 pieces of PVC pipe all around it. Several smaller pipes were then installed to reduce vibrations before everything was assembled using 300 nuts and bolts. Read more for the build and test video.

DIY Perks Homemade USB-C Mirocphone
Inventor Matthew Perks of DIYPerks is back at it again, and this time, he’s managed to build a sleek USB-C microphone from scratch that rivals far more expensive models.
How so? The most important part was finding the same microphone capsule used in the CAD E100S, a $600 USD microphone. Next, he had to build a basic pre-amplifier that boosts its output up to line-level.

DIY Working Functional Submarine
Inventor Matthew Perks is back at it again, and this time, he’s successfully built a working submarine with full buoyancy control. Now before you get too excited, this isn’t something a person can dive in, but rather a smaller model that comes equipped with large syringe-like devices in the fore and aft to compress or decompress water.

Unpickable Lock
Let’s face it, even the most secure locks can be picked by professionals, but is there such a thing as an unpickable lock? Shane from Stuff Made Here just might have built one. Standard pin tumbler locks can be picked by lifting or bumping the pins while placing tension on the cylinder pins. This innovative design prevents the pins from being set in an unlocked position individually, by locking them in the position they are set, thus preventing someone from bumping them.

Napa Backyard Matterhorn Roller Coaster Ride
Many people were stuck at home during the COVID-19 pandemic lockdowns, but one Disneyland fan from Napa, California, decided to make the best of it. Since most theme parks have not yet reopened, graduate student Sean LaRochelle decided to create a miniature version of the Matterhorn roller coaster in his backyard, complete with a yeti. The two-story coaster project began at the end of March, and was finished in July.

For those who haven’t been keeping up to date with Tesla, the Cyberquad is basically an all-electric quad bike unveiled in November 2019 at the Cybertruck press event in Hawthorne, California. There are no power numbers, but Elon Musk did say that it will come at first as an option for the Cybertruck. Inventors Rich Benoit and Steven Salowsky didn’t want to wait the 1+ years for the official release, so they built their own. Read more for a video and additional information.

Panasonic Komoru Work Home Cubicle
Many have been forced to work from home due to the pandemic, and let’s face it, sitting in your living room isn’t the ideal place for productivity. So, Panasonic came up with the Komoru.

Game designer and developer Tyler Glaiel has created an interesting voice-activated face mask, or to be more specific, a panel of LED lights that can mimic someone talking or smiling even when the protective cloth is worn. This mask basically consists of an 8×8 set of LED lights in a flexible matrix that fits in the pocket of a standard face mask, which are linked with electrical tape to a 9-volt battery and a microphone. An Arduino Nano microcomputer contains the software coded to run everything. Read more for a video of it in-action and additional information.
