Useful electronic homemade products
Since the size of the site bgv.electricianexp.com every day it becomes more and more, there are many new articles, it is quite difficult for new visitors to immediately navigate and review at a time everything already written and previously posted.
I really want to draw the attention of all visitors to individual articles that were posted on the site earlier. In order to not have to search for the necessary information for a long time, I’ll make a few “input pages” with links to the most interesting and useful articles on specific topics.
The first such page will be called "Useful electronic homemade products." Here we consider simple electronic circuits that are available for implementation to people of any level of training. Schemes are built using a modern electronic base.
All information in the articles is presented in a very accessible form and in the amount necessary for practical work. Naturally, for the implementation of such schemes, you need to understand at least the basics of electronics.
So, a selection of the most interesting articles on the site topics "Useful electronic homemade products". The author of the articles is Boris Aladyshkin.
The easiest twilight switch (photo relay)
The modern elemental base of electronics greatly simplifies circuitry. Even an ordinary twilight switch can now be assembled with just three parts.
Automatic pump control in the country
The article describes a simple and reliable control circuit for an electric pump. Despite the extreme simplicity of the circuit, the device can operate in two modes: water lifting and drainage.
Spot welding in the home workshop
The article provides several diagrams of spot welding machines.
Using the described construction, it is possible to determine whether or not a mechanism located in another room or building works. Information about the work is the vibration of the mechanism itself.
How to make a safety transformer
A story about what a safety transformer is, why it is needed and how it can be manufactured independently.
How to protect against voltage fluctuations
Description of a simple device that disconnects the load if the mains voltage goes beyond acceptable limits.
The article discusses the scheme of a simple thermostat using an adjustable zener diode TL431.
Simple power control for smooth lamp on
An article on how to make a device for smooth turning on lamps using the KR1182PM1 chip.
Step up power regulator for soldering iron
Sometimes, with a reduced voltage in the network or soldering of massive parts, it becomes simply impossible to use a soldering iron. Here the power regulator for a soldering iron can come to the rescue.
Electronic heater for oil cooler
An article on how to replace a mechanical temperature regulator of an oil heating radiator.
Thermostat for electric boiler
Description of a simple and reliable temperature regulator circuit for a heating system.
Simple converter 12V to 220V 50Hz
The article describes a converter circuit made on a modern element base, containing a minimum number of parts and allowing to obtain significant power in the load.
How to connect the load to the control unit on microcircuits
An article about various ways to connect the load to the control unit on microcircuits using relays and thyristors.
Description of a simple LED garland control circuit.
The design of a simple timer that allows you to turn on and off the load, at predetermined time intervals. The operating time and pause time are independent of each other.
Description of the scheme and principle of operation of a simple emergency lamp based on an energy-saving lamp.
PCB manufacturing using a computer
A detailed story about the popular "laser-ironing" technology for the manufacture of printed circuit boards, its features and nuances.
