Building a DIY drone test rig is essential for safely testing mini-drones without the risk of crashes or component damage. This comprehensive guide shows you how to build a 3D printed drone testing stand that allows complete flight testing in a controlled tabletop environment. This drone test stand was originally built for our LiteWing Drones, but you can use it to test any mini drones.

Lizard is a remote-controlled race car project published by TRDB. It’s all 3D printed components minus the wheels and powered by a custom electronics system based on the ESP32 microcontroller. Designed to be customizable, the Lizard features a rear-wheel drive system with open differential, independent suspension, and double Cardan joints. The drivetrain and chassis are printed using PETG…

In 3D modeling, precise and fluid navigation around a digital object is essential. Even though there are plenty of commercial solutions available, none of them are pocket-friendly. That's where a DIY solution can shine without making a hole in your pocket. In a recent video, the YouTube channel Just Make It showcases a custom-built SpaceMouse that replicates the functionality of commercial 3D…

A maker has designed an impressive DIY hovercraft that can glide over water, grass, and hard surfaces using a powerful air-cushion system. The body is made from four modular parts, 3D printed to fit standard printer sizes, with strong mounting points and precision bearings for smooth mechanical movement.

The hovercraft uses two motors, one for lift and one for forward thrust. A 5-inch…

We’ve seen multiple DIY drone projects over the years, each bringing something unique to the table. At CircuitDigest, we even built our own version of a Wi-Fi controlled drone using the ESP32, which later evolved into LiteWing—an open-source drone development platform aimed at makers and researchers. Continuing in this spirit of accessible drone building, Vishal Sharma from the YouTube channel…

Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding what is amplitude modulation and how it works is fundamental for electronics engineering students and professionals working with radio frequency circuits. This…

A combination of an old hoverboard, a go-kart tire, and some clever engineering apparently gets you a functional one-wheel electric ride that rides like a snowboard both on and off the road. A DIY creator from the YouTube channel Well Done Tips took what he believes to be one of the most useless electric rides ever made and transformed it into a surprisingly cool custom one-wheel electric…

If you have ever watched a rocket launch and wondered how it stays steady during its fast ascent, you are not alone. Rocket flying is not just about power, it is about control and precision. That is exactly what ‘BPS.space’ focused on their latest project.

Before this project, the team worked on a few other rocket designs that helped them learn a lot about what works, and what doesn’t.…

If you have ever wondered what could be done with a simple RC toy, YouTuber ‘Basement Creations’ has transformed the toy into a fully functional autonomous rover, complete with GPS navigation and telemetry.

The base of the project is a toy modeled after the real-life Ripsaw vehicle, known for its unique double differential steering system. Powered by an Arduino board and motor driver,…

What if you could get an instant SMS alert the moment a fire or smoke is detected at home or office? Through this project tutorial, you can build a fire and smoke alarm system using Arduino UNO R4 that sends real-time SMS notifications. This means you will immediately get alerted even if you are far away.

In this Arduino Project, you…

In this project, we’re making an ordinary two-wheeler helmet smart using an RF Transmitter & Receiver. The best part: this Arduino-based smart helmet is simple to build and does not require advanced engineering knowledge or complex components.

Build Time: 6-8 hours | Cost: $40-60 | Difficulty:…

A DIY The Wrench maker has built a smart desk dustbin with an automatic iris-style lid, adding both functionality and a unique touch to a workspace. After some adjustments, the final design was printed successfully using a 3D printer using a design made in Fusion 360. Different filament colors were used to make the dustbin visually appealing. 

The smart feature of the dustbin is…
