In this post, are shown the necessary concepts to make analysis of magnetic circuits, which is very similar to that of electric circuits.
Astronomers observed a star devouring a planet
For the first time, telescopes observe a planeta 10 times heavier than Jupiter being swalloed by a star at 12,000 light-years of distance.
Arduino with Bluetooth module HC-05
In this post, it’s shown how to control an Arduino with a smartphone using an easy method, through a Bluetooth module HC-05 or HC-06.
Hysteresis: what is it?
The hysteresis is very common on materials and systems. It’s the capacity to keep a property, after remove the stimulus that induces this property.

James Webb measures an exoplanet’s temperature
For the first time, James Webb Space Telescope (JWST) measures the temperature of an exoplanet of star system TRAPPIST-1, and it’s 230ºC (446ºF).
Omnidirectional Mecanum wheels
Vehicles with Mecanum wheels can move in all directions, using less time and space. The operation of these wheels is this post’s subject.
What is tidal locking?
Why the Moon is always facing the same side to Earth? The answer is tidal coupling or tidal locking and it is this post’s subject.
The first ultrathin and compact metalens
Was developed the metalens, a new type of lens for telescopes and cameras, which can be flat and operates on near-infrared region.
