This post is the continuation of rare earth subject. I will talk about the main rare earth reserves and some applications of each element.
Brushless motor
This post’s subject is about brushless motor. This type of motor is much used in drones and model airplanes for be light and has great rotation speed, making it good to move propellers. Not all drones use brushless motors. Are used also in coolers (computer’s fans).
How DC motors work?
In this post I will explain how the DC motors work. This is a basic concepts post it will be important to understand future posts.
Rare earth (Part 1)
In this post I will talk about rare earth, fundamental elements to modern technologies.
Electronic muscle
Traditionally the actuators which move robots are electrical motors, but these aren’t the only way to move robots, an alternative are the electronic muscle, which are this post’s subject.
Arduino tutorial (Part 3)
In the third part of this tutorial, I will show how to use servomotors and new commands. This post has been updated.
Does cellphone causes cancer?
Cellphone causes cancer. Urban legend or scientific fact? It is the subject of this post.
What is plasmonics?
In this post, I will show the plasmonics. It is an emerging field that leads with plasmons, which are electron waves generated by light.
How to generate energy from garbage?
One of the greatest environmental problems today is the big quantity of garbage produced currently. It is a great idea to transform all those garbage in energy due to big demand of electrical energy. How to generate energy from waste is this post’s subject.
Introduction to artificial neural networks
In this post I will give an introduction about what artificial neural networks are, how they work and your applications.
