It’s easy to live on your car’s battery without wasting the life of expensive batteries.

Have you ever forgotten to turn on the turn indicators after performing a maneuver?

The standard clatter from the front panel is always easy to hear, especially when music is playing in the cabin, so I recommend adding a simple turn signal signal circuit to your car with your own hands.

The cigarette lighter is one of the rare automotive tricks, because in the entire hour of its appearance, the axle has already retained its cob structure for over 70 years. As a result, both vintage cars and modern models have the same design stuck in place. In the old days, only one function was used, although today’s “information world” has several different functions, a connector for charging different digital devices is allowed gadgets or start the car. Radio amateur circuits turn signal indicators Designed for working only with LEDs in the brake lights of your car, if you still use the original bulbs, you can easily repeat the design of the turn signal indicator.

Long, and you still have to deal with transport features, such as the carburetor. Well, as you know, your normal robot will be provided with various devices, among them mainly the economizer. Let's talk about this, and also take a look at the diagram of the kerosene stove economizer system.

idle for VAZ cars A car starter is a device that ensures the engine starts after turning in any weather conditions. Mostly all starters, by their very nature, are electric motors of short-stroke action, or high voltage. Start cycle typical annex consists of three trials with a 30 second interval between them.

Since the car's remains share a single source of electrical energy (battery), the engineers chose a permanent source for the electric motor starters. Kozhen car vlassnik, who sits behind the kerm budget car

knows how long it takes to check the heat supply from the engine when it starts up winter hour fate, especially if you live near the outermost part of the world.

An hour to set a comfortable temperature here at 30, and so on. The best idea The biggest problem, in my opinion, is heating the car interior with a fan heater. To put the idea into practice, I used an old toaster and a faulty computer unit. A sound signal begins to generate, indicating trouble.

The main advantage of the other battery is that the accumulated energy is drained through the additional battery, and the first one is kept in reserve, so you don’t have to worry about the car’s factory after a picnic on the road civilization. A lot of foreign cars are already being sent to each other rechargeable battery

under the hood.

The problem with them lies mainly in the parallel connection of 2 batteries This radio design is suitable for charging most smartphones and tablets using 5 volts when the light is switched on. Or you can power the video recorder with a length of 40 hours when the car checks its owner in the parking lot.

The basis is the circuit of the AVR Tiny13 microcontroller, the firmware is being updated. Kozhen Vlasnik passenger car To the best of your ability, you try to paint your car. Moreover, the older the car, the better it is to build a supercar out of it, equipped with the latest advances in science and technology.

Installed for a car with your own hands and tested on your own, maybe for the benefit of not only us, we are presenting a small digest of simple devices that will make the life of a motorist easier.

• Get the catalyst
• If you remove the catalyst with your own hands, you can run into many difficulties.

After soldering, the entire structure is coated with insulating varnish and placed in a thermal chamber.

The control lamp can no longer be imagined.

A very brown and simple device.

For this preparation we will need an old flame-igniter.

When the spark breaks through the housing, the spark on the contacts occurs periodically, and manifests itself in the unstable operation of the engine.

To check the spark plug, there are special tools, but there are none in the arsenal; a replacement will be needed in the future.

We remove the chemical element from the igniter, apply the dart and insulate it so that it does not splatter. We install the attachment on the candle as shown on the little one, press the button and carefully watch the contacts. If the spark has jumped, the spark plug is 100% working.

The simplest charging device

Of course, every motorist is happy to face the situation when it is necessary to charge the battery, but there is no charger at hand.

If you think that selfishness is the lot of little ones and a home-gift that is in need, we will soon see your amends.
