I found such an amplifier on Aliexpress. It was attracted by the meager price (12 rubles) and miniature sizes. It is a ready-made module for two channels, dimensions 18x21mm, power 2.5-5 volts, power

For any electronic device, power is necessary, if it requires energy 24 hours a day, then its best source will be an electric network. Here the choice usually stands between the so-called

A simple miniature amplifier built on a specialized low-voltage microcircuit audio amplifier LM386 can be used as a low-power headphone amplifier. This is relevant in

China provides for a small price a huge amount of not only electronic devices, but also their components. A small matrix made up of light emitting diodes can show you what you need

Thermistors have a very useful property of changing their resistance depending on their temperature. Thanks to this phenomenon, it is possible to create various temperature sensors that monitor

An optocoupler is a very useful feedback device. Usually you can meet an optocoupler in circuits with a signal transmission between parts of the circuit with different voltages,

A small low-voltage voltage converter is often used for the manufacture of so-called external batteries (power bank). The fact is that for the charge of most modern

A compact, pulsed, low-power, low-voltage power supply unit with 110/220 V power supply and 5 V output with a current of up to 0.7 A, that is, with a maximum power of 3.5 watts, it may be needed as a source

Every fisherman who loves fishing in winter has met with such an unpleasant feeling as severe freezing of his hands. There is no longer fishing, all thoughts on how to warm frozen hands. Rummaging on the site

A very small, but remote pulse voltage regulator on an LM2596 chip in an eight-pin planar case. It has excellent characteristics and at the same time it heats up minimally, and even that

An optical quantum generator is now available to everyone at a low price, this is a unique device that can convert energy (in our case, electric) into light, monochromatic

In order to make the bike look more completely Chinese masters come up with different gadgets, and now I will talk about the cheapest bicycle computer (or just a speedometer) MBI-67. it

Hello. Today I want to talk about the YL-63 obstacle avoidance sensor. It is mainly used for various robot models on ARDUINO and not only. With it you can "find"
