The main trend in the modern automotive industry is the use of electric drives in production vehicles. It is impossible to organize conveyor production of cars in a garage, but even a novice mechanic can assemble one electric car. IN

The supply market is overflowing with various flashlights for every taste and budget, but today we will look at how to make a very high-quality thing yourself and literally from available materials. Most flashlights sold are based on the most

You can put on a real show at home or just “let in the fog” using a homemade fog machine. 01 The heart of the device is an electric hair dryer. The cheapest model will do, for 350-400 rubles. Even if there is an old “grandmother’s” hairdryer lying somewhere, it too

External chargers are very compact in size, and their transportation does not present any difficulties.However, if you look at things with your own eyes, not every one of us carries this useful gadget with us. There is plenty for that

Having problems with power supply, the issue of obtaining hot water for technical needs is greatly complicated. An effective solution in such a situation would be to use a solar water collector. It will allow you to heat water from sunlight to 40

It will be very cool if you make this mini tester and always carry it with you in the car. After all, with the help of it you can: check the functionality of lamps and fuses without removing them from their seats, find out the polarity and presence

To heat a garage, workshop, chicken coop or even a house, you can use solar collectors, which make heating practically free. Such devices collect thermal energy from the Sun and direct it into the room, using

Hi all! Once I wanted to throw a broken cell phone charger in the trash, but then the thought arose that maybe it could be useful for something else. I decided to disassemble the case and look inside. A classic scheme appeared before me

The drill is a very convenient tool for performing precise grinding, cutting and drilling work, especially if it is powered by a battery. However, the cost of such a tool in a stand-alone version is quite high, so if desired,

Electric motorcycles are very profitable in terms of operation, but since they are a new product, they are still expensive. If the appearance of the equipment is not critical for you, then you can convert almost any light motorcycle or

High-speed 12 V motors can be used to make various power tools, including a homemade lightweight cordless angle grinder. The cost of its assembly is quite low, since many parts can be removed from

There are many interesting DIY electrical projects that require converting low voltage DC to high voltage AC. This may be needed when assembling a homemade plasma lamp, or just for

Car generators, due to their design, are small in size and have very high power. It would seem that such a tiny thing can easily produce an average of 2000 W of power (there are models up to 5 kW). The generator cannot work as

Most office network fans use asynchronous motors with a squirrel-cage rotor. Such a motor can only convert electrical energy into mechanical energy, but not vice versa. When rotating its shaft, it is forced into its

Soldering aluminum with standard solder using conventional technology is unreliable and impossible. The tin on it rolls into a ball, not wanting to stick, and if it does stick, the result is a weak connection that breaks under the slightest load. To
