When the idea came to use a car headlight as street lighting, the question immediately arose about the power of such lighting. Using a “native” 12-volt light bulb proved to be problematic - the transformer does not fit into the headlamp! There was no desire to separate the weatherproof housing separately for this and lead from it to the headlamp a wire of large cross section.

In this review, the author shows how to make a small grinding machine for working in a home workshop from available materials with your own hands. The author uses an electric motor from a washing machine as a drive. Its power is 180 W. This power is enough to sharpen a tool or grind small workpieces.

Experienced joiners know how important it is to keep an eye on the cutting edges of chisels and chisels. They stumble very quickly, and for correct sharpening it takes a lot of time. In addition, the formation of dents or other large mechanical damage on the edges makes the process much more difficult, and sometimes tools have to be thrown away.

Every man probably has a piggy bank, casket or box in which he prefers to keep his stash so that sooner or later you can use it to buy something valuable or give something special to your soulmate. But there is also a so-called piggy bank just to save money “for a rainy day”.

Tiles and stone are very durable materials, so they should serve for a long time, without requiring intermediate repairs. If the tile falls off or, moreover, breaks down during operation, then the cause is most likely due to problems with the masonry mortar or errors in its installation. For high-quality tile laying, the method of applying tile glue (masonry mortar) is of great importance.

In small home workshops, and especially in garages, you often have to fight literally for every centimeter of free space. In such conditions, it is sometimes difficult to compactly place tools and machines. However, there is always a way out. For example, in this review, the author proposes to make a universal mobile table for an electric sharpener and a grinder with his own hands.

Who would have thought that the simplest inverter can be made without the use of transistors, microcircuits, and complex circuits. Last time I showed how to make an inverter without transistors on a relay. As it turned out, this is not the only way to build an inverter. I will show how you can convert electrical energy from DC 12 V to 220 V AC.

In this review, the author shows the manufacturing process of a home-made three-roll machine for rolling strips and sheet metal. The design is simple, but for the manufacture of some parts you will need a lathe. First of all, the author cuts out two square-shaped plates. After marking with a crown, you need to drill a hole in the center of the workpiece, and then cut the groove with a grinder.

95% of the world's population have personal computers, and with them many digital media for storing information. One of these devices is a computer disk, which, like any other thing, has its own life. Moreover, it is easy to damage. One or two scratches - and you can send to the landfill.

An interesting model of a motor powered by electromagnets is presented in the video. The principle of movement is based on applying voltage in turn to two coils, from which the magnetic field changes and the connecting rod rotates the shaft, switching the current supply to the magnet. This engine model is a single mechanism and can be an interesting craft for everyone.

For high-quality welding of round metal pipes, it is necessary to ensure a good fit of the workpieces. To do this, cut the saddle at the end of the pipe. To do this as accurately as possible help a homemade adapt. Moreover, it should be noted that this homemade product is in no way inferior in quality to factory models, but it will cost much cheaper.

The image of a swallow, a symbol of the beginning, the arrival of spring, kindness, good luck and fidelity, is often used in paintings, embroideries, tattoos and other artistic creations. The popularity of using visual motifs with a swallow is due to the positive influence of this symbolic image on the course of life events.
