Adding Landing Gear & Antenna For legs (landing ... like on my Arduino drone. This DIY ESP32-powered drone combines performance, affordability, and customization. Whether you go 3D-printed or PVC, add ...

The 3D-printed drones cost between $2,000 and $3,000 each. The biggest challenge has been getting parts approved by the Defense Department.

Not so nice, though, is the poor WiFi performance of some of these boards, which [Peter Neufeld] addresses with this quick and easy antenna. There are currently a lot of variations of the ESP32-C3 ...

How a special nitinol compound and 3D printing was used to create the shape-shifting antenna. An overview of materials and heating problems they encountered, and how they overcame them.

I knew I wanted to create a 3D-printed version. Turning an image into a 3D model can be complicated, sometimes involving large camera rigs and a lot of clever software, but the latest AI ...

The medical sector is one of the largest spaces where 3D printing operates, with continuing developments for implant customization, educational models, and drug manufacturing. The topic has ...

Fidget toys are a niche all their own when it comes to 3D printed devices. The fidget knife has a satisfying snap action to it, and this printable linear toggle design is practically a fidget toy ...

3D printing is a downright futuristic technology. People can use plastic filaments, resin, and other materials to create custom objects. The quality of the print is limited by a user's printer ...

But that didn’t stop Kevin Frias of Minneapolis, Minnesota, from attempting to engineer and 3D print his own version of the Canyon Aeroad in less than a week—just in time for his birthday.

Abstract: This work describes the design process, manufacturing, and measurement of an antenna system consisting of an on-chip feeding element enhanced by 3D printed parasitic resonators operating ...

There are plenty of small ESP32-C3 IoT boards with a USB-C connector on the market, and while they all look very similar, antenna designs differ, and less thought-out ones may severely impact the WiFi ...

Additionally, due to its unsupported angle and higher center of gravity, the new antenna was swaying excessively—even with minor road bumps or turns. The print took approximately 60 minutes and used ...
