October 2025. A maker uploaded a video to YouTube. The title was "Build an ESP32 RC Submarine with FPV Camera". Just $117. An ESP32 microcontroller and a 3D printer. An acrylic pipe and a syringe. By ...

Magnetic fields are all around us. We can’t really feel or see them ourselves, per se, but we can map them with the right hardware, like this device built by [edosari50]. The build uses an ESP32 ...

We've all heard that "if you want something done right, you have to do it yourself." And that's usually fine when it comes to tasks at work or baking your own birthday cake. But if you want a specific ...

AS5X47 is a library for connecting AS5047 and AS5147 magnetic encoders to Arduino boards. It allows to easily read the angle measured from the sensor and also advanced features to reconfigure the ...

The MT6701 library provides a simple and effective way to interface with the MT6701 magnetic rotary encoder using ESP32. It supports reading angular positions in radians and degrees, calculating ...

What if building a robotic arm didn’t require a massive budget or a team of engineers? Imagine a device capable of delivering smooth, precise movements for studio applications, constructed for less ...

Aerial manipulation systems are highly attractive for various applications due to their distinctive features. However, the systems discussed in the literature are constrained by either a restricted ...
