I decided to put together a column from what I had. I went through the workshop and collected components. The speaker will serve as a phone music amplifier. She will play louder than the last one. So, it will be wireless. I found one column in the deposits. It seems from

Few people know that you can assemble a 220 V electric generator with your own hands. It's not as difficult as it might seem. You can make such a device at home using readily available parts.

A small, low-voltage refrigerator will be a great helper on hot summer days. You can use it in a manish or place it on your desk at work. This mini miracle will preserve your food and cool your drinks at great speed. Collect

The Power Bank is small in size and can be taken with you anywhere if desired. Pocket 220 V sources can be extremely useful and will allow you to power low-power electrical appliances that can only operate from mains voltage.

To cut small pieces of wood, plywood, plastic, aluminum and even steel, you can make a mini tabletop miter saw. It is very compact, convenient and quite quiet. This is a simple design that even a person can repeat

A very simple mini air conditioner that perfectly releases cooled air is very easy to build at home with your own hands. The air conditioner is built as a fan with a heat exchanger based on a Peltier element. The entire installation runs on 12 Volts

Few people thought that you can get 500,000 V at home without transforming the voltage, but by generating it from a mechanical energy source. This requires only a special electric generator. Anyone can assemble such a device if

In the first article I talked about how to remake an ATX power supply. Implemented current and voltage regulation. Now you need to make adjustments to suit your needs. I will set the voltage range from 5-6 to 15 volts.

Soldering sometimes has to be done in places without an electrical outlet within reach. In this case, you can make a special nozzle for the gas burner. With it, electricity is not required for soldering.

If you have a small party with dancing, then this small device will help you create spectacular lighting. This LED installation has a very small size and a powerful luminous flux. Fits in your pocket, works from

I have accumulated a number of computer power supplies. You can use them for their intended purpose. But I decided to do things differently. Moreover, the power is already low, mostly 200-300 watts. Do-it-yourselfers often modify them to suit their needs. And I

Many old laptops with very good hardware have problems with insufficient memory. If at the same time they have a disk drive that you no longer use, then you can install an SSD solid-state drive in its place. As a result, memory

When performing electrical installations, it may be necessary to connect wires. This is done in different ways. Often everything is solved by twisting and soldering, but you can also use faster, more reliable methods.

A generator for generating autonomous electricity can be made not only on the basis of DC motors, but also assembled literally from scratch. It is quite possible to make a generator at home from wire and magnets from a broken microwave

Free electricity is the dream of many, but to get it, you need to spend a lot on equipment.If you are not ready for such an investment, you can make a wind generator with your own hands literally from trash. Of course it won't provide electricity.

Many people have in their bins old, still functional, music centers designed for cassettes and CDs. Since musical media for them are outdated, they are practically no longer used. However, do not throw away such equipment

Fishermen and simply those who like to ride a motor boat on shallows and shallow rivers often encounter damage to the propeller on the bottom of the reservoir, as well as plants getting wrapped around it. An airboat is more suitable for moving in such conditions. She

The switch is designed primarily to control 12-volt automotive safety lighting bulbs, which are installed in cellars and other places with high dampness, where this is required for electrical safety reasons.

You can make a 220V alternating current generator for undemanding household appliances with your own hands. To do this, you will need a couple of transformers from microwave ovens, and a few more available spare parts. As a drive for it you can

If you have a power supply from an old computer lying around, you can easily use it and turn it into an adjustable, laboratory power source. This instruction is good because it does not require knowledge of pulse circuitry

Mobile phones become obsolete very quickly and are replaced by newer models. The old device, of course, can still serve, but it is no longer relevant. Over time, most people accumulate truly entire deposits of such devices. Give them

Wireless energy transfer is a very hot topic nowadays. Every day there is an incredible development of technology in various fields of science. Progress does not stand still, and some technologies that previously seemed new are now

When connecting household appliances and various electrical equipment, it may be necessary to determine their level of energy consumption in a certain mode. To do this, you can make a special extension cord. Electronic components for it

Fans are very effective at saving you from the heat; unfortunately, it is not always possible to use them. But that's definitely not the case with this DIY portable battery-powered fan. You can carry it with you even to work or school.
