When repairing boards, it becomes necessary to desolder components. This requires removing melted solder on each individual leg. The fastest and most convenient way to do this is with a tin pump. Such a device can be assembled on the basis of a compressor from

It is possible to assemble metal structures from profile pipes without welding. There are many ways to connect them, which, although more complex to implement, are quite worthwhile. For small volumes of work, it is better to tinker longer than to spend money on welding

Due to their versatility, step drills are used more intensively than conventional ones, and therefore lose their sharpness faster. The cost of such equipment is too high to change it every time the cutting edge becomes dull. There are ways to

The grinder is a universal tool, but there are limitations in its use. By equipping it with various attachments, functionality and security can be expanded even further. Make such a device for it, and your angle grinder will replace the emery.

Most people use a portable barbecue made of sheet steel, which after a couple of uses becomes deformed due to high temperatures. If it is used when traveling to the forest, to the beach or fishing, then thanks to its mobility this disadvantage can be overcome.

I decided to fix the cracks on the plastic panel of my battered truck using a technology I had seen in videos on YouTube. It is based on the interaction of ethyl cyanoacrylate glue (any superglue from the store) and an alkaline compound (soda).

If you forget about the seeds planted in a pot, then without light and water after germination, the seedlings become very elongated. They turn out thin, white, with an absolute deviation from the norm. Usually they are simply thrown away, but there is a way to save them and get them into

The simplest dimmer consists of only 5 parts and is capable of adjusting load power up to 2 kW at an AC voltage of 220 V. Even a novice radio amateur can cope with its repetition, the main thing is not to forget about safety precautions when

The car heater radiator has very fine honeycombs, so when antifreeze is rarely replaced, it becomes clogged with rusty scale.To avoid freezing in winter, install this filter in front of the cabin heater. It will remove all large and medium fractions from antifreeze,

Copper, nickel, brass and aluminum are resistant to corrosion, so a thin layer of them on the surface of the steel can protect it from rust. One metal can be deposited onto another using electrolysis. But it doesn't always work. Let's check

To solder various small items, you need a soldering iron of the appropriate tip size, which will also not overheat circuits and miniature electronic components. You can make it yourself from a 10 Ohm resistor. The special feature of this soldering iron is that

The cause of clogged bathtub siphons is hair and fur. They accumulate inside and block the possibility of draining water. It will not be possible to break through such a blockage with a plunger or dissolve it. You can remove hair from the drain without disassembling it in a simple and quick way.

Modern tomato varieties have great yield potential, but cannot use it to its fullest. The small root of the plant is simply not able to absorb enough nutrients from the soil to support the entire ovary. In this regard, it is important

Welding skills develop with experience. It is quite normal if, at first, when welding, thin-walled metal is burned through, the seams lie unevenly, and sloppy beads are obtained.In order for welding to be acceptable the first time, you need to adhere to

During construction, it is very important to adhere to precise horizontal and vertical lines. Even constant use of a bubble level does not guarantee that everything will turn out smooth. This instrument is often sold defective, or its settings are lost.

When making a greenhouse, it is important that each pipe arch has the same bending radius. If you have a pipe bender available, then preparing identical parts is not a problem. In its absence, the required level of accuracy can only be achieved by collecting

When laying laminate flooring, a situation may arise when a vertical water supply, heating, or gas pipe interferes with the wall. This is one of the most difficult areas, but it can be laid beautifully. Bypassing the pipe is done simply, although it requires

Hair accumulates in the bathroom siphon. If they are long, then it is impossible to push them further along the pipe with a plunger. Some of them can be pulled out through the drain grate with a hook, which solves the problem for a while. If the hair accumulates in the depths

After the screwdriver battery fails, it can be switched to a 220V network. This requires only an adapter and a power supply.This is a very simple modification that does not require much time or large expenses.

It is convenient to use a miniature drill for drilling circuit boards or making parts for modeling. It is light, quiet, and does not take up much space. Sometimes even the smallest drill on sale is too big for delicate work. If you haven't found

A scriber (scriber or Scriber) is a tool for marking metal surfaces. Such products of various designs are produced by industry and in terms of quality they differ greatly. To avoid wasting money, you can

For many jobs, a full-size heat gun is too big. For delicate tasks, you can use a homemade hair dryer with a thin nozzle. They are convenient for setting heat-shrinkable tubing, spot heating plastic, drying two-component glue, etc. This is done

Granite, and most other types of natural stone, are much more difficult to drill than concrete or metal. Since this rarely needs to be done, most simply do not know how to do it, as well as how to install fasteners into the resulting hole.

There is no universal soldering iron that can solder both twisted wires and SMD components with equal quality and convenience. There is an ideal device for every task. Some of them you can literally do yourself.
