This is the second part about BJT polarization. Are shown projects of circuits with fixed and emitter’s stable polarization.
Meeting requests, this post’s subject is the Möbius strip. It is a simple structure, but interesting and inspiration source for many professionals.
This post’s topic is graphene. It is one of carbon’s allotropic forms and promises to cause a technological revolution due to it’s properties.
Today are shown how Hall effect works, a magnetic sensor using this phenomena and how o use it in projects with Arduino.
New materials to create more durable and efficient batteries are wanted. Many companies and laboratories are developing fluoride batteries. Today is shown these batteries and theirs promises.
In this tutorial, it is shown how to use joystick module in Arduino to make projects. This module is similar to the model found in Playstation controls.
In the third part of operation and parameters of lamps, the subject is about high intensity discharge or HID and neon.
This is the second part of operation and parameters of lamps. Are shown luminescent lamps: fluorescent, ESL and LEDs.
This post is the first part of operation of all types of lamps and a comparative of parameters between the existent technologies. This part is about incandescent lamps.
This is the second part explaining various types of antennas. Reflecting antennas are this post’s subject. Reflectors serve to increase directivity.
