What are ICE (In Circuit Emulators) and how do they work?

Reading time: 5 minute The emulator is a high-performance solution for developing microcontroller applications. If in electronics without microcontrollers the oscilloscope is used, in applications with microcontrollers the circuit emulators are also used. It is the most efficient way to see what is happening inside the microcontroller.

EasyEDA Tutorial - Browser-based PCB design

Reading time: 4 minute In this article we will present how you can turn your idea into an electrical / electronic scheme and finally into a PCB that can be created either by you or by a specialized company. We have chosen to present in this article the EasyEda software because it is very simple to use for beginners, being browser-based (you can continue working on the design from any PC) and it is free.

Manufacture of printed circuits in our own laboratory - Part II - How do we develop the exposed laminate?

Reading time: 8 minute Development - the important stage in the manufacturing flow, the final aspect of the printed wiring depends on it. It is a relatively simple chemical process in which the precautions are more protective of work (rubber gloves, goggles, gown or overalls, nose / mouth mask, etc.) than technical.

Manufacture of printed circuits in own laboratory - Part I - Photographic method

Reading time: 7 minute The manufacturing process that will be presented below, entitled photographic process, is one of those that offers excellent quality of the printed circuit board because it uses the photo method to transfer the image of PCB layers (respectively Printed Circuit Board) on copper-plated laminate. .

10W bass-boost amplifier - What is bass-boost?

Reading time: 2 minute The presented amplifier is based on the AO dual NE5532 integrated circuit and develops a power between 9.5 and 11.5W, being differentially powered up to +/- 18V. Because amplifiers of this type are commonly used for small speakers, the bass frequency range is quite small (insignificant). Therefore, a bass intensity control was introduced in the feedback loop of the amplifier, to overcome this problem without quality loss (max + 16.4db at 50Hz).
