Lately we see many commercial products that allow you to levitate light objects using a magnetic field. There are already assembled kits, but today we will see how to build a more simplified one at home. The project uses an Arduino Nano that controls an electromagnet through a power transistor based on the signal received…
Let there be light! In this tutorial we’ll build a basic magnetic levitator. This guide will go over some of the theory, how to use a magnetic field sensor, and how to use one to build a basic levitation circuit. Finally, we’ll go a bit further and build a wireless power floating light. …
If you thought the power of levitation was only available to magicians, maybe you have to check out this amazing project. “We present Ultraino, a modular, inexpensive, and open platform that provides hardware, software and example applications specifically aimed at controlling the transmission of narrowband airborne ultrasound. The software can be used to define array…
