Electronics for everyone 07/2016

Description

Editor-in-chief recommends

Amateur seismometer
The author shares his experiences related to the construction and improvement of the shock detection and recording system. The given tips and extensive documentation should be an encouragement and inspiration to address the subject of measuring seismic vibrations.

USB Audio DAC, or external music card
Integrated computer music cards often have poor performance. Do you want to easily check how much the sound quality will change after using an external card with the Texas Instruments PCM2706 / 07 chip?

C language course
In the main part of the course we deal with counters - timers, while in the articles "Around the C language" we get closer to the functions, and to extend the horizons, we look at the structure and operation of assembler commands.

Electronics for junior (and senior)
As part of the seventh meeting, we examine the properties and imperfections of the capacitors. We measure the capacitance, leakage and ESR resistance in a surprisingly simple way and we are also very surprised by the effects of dielectric absorption.
