2 projects of BJT common emitter amplifiers
In this post, it is shown how to design a BJT amplifier with voltage divider on common emitter mode. Two examples of projects are presented.
Charge controller: how it works?
I received a doubt about the charge controller for solar power generation. This component is very important for off-grid systems.
How CCD sensor works?
The CCD is the abbreviation of Charged Couple Device. This light sensor is very used to obtain images in digital cameras, telescopes and smartphones.
Liquid mirror telescope
This post’s subject is the liquid mirror telescope. The operation, advantages and disadvantages and, some projects are shown.
Wall climbing robots
How do the adhesion mechanisms used by wall climbing robots work? In this post, are shown the three forms of adhesion.

Cosmic rays: what are they?
The cosmic rays are a set of particles with high energy that arrives at Earth’s atmosphere every day, at speeds close to the light.
3D priting of nanostructures
New materials can be 3D printed, to create many nanostructures and improve materials’ resistance without increasing weight.
