What can be done from a non-working screwdriver. How to convert a cordless screwdriver into a corded one - options for craftsmen. How to use a corded screwdriver - simple rules

A cordless screwdriver is a great helper in the household. The tool works together with the master in the house and in the garden, works in the garage or in the field. Until the battery runs out. The number of charge-discharge cycles of a battery is limited; the battery also deteriorates from idleness: self-discharge destroys the cells. On average, a battery lasts 3 years, after which it has to be replaced. You can save the instrument by converting it into a network one. Remodeling is done in different ways.

Is it really worth redoing?

Without batteries, a screwdriver turns into a piece of iron. When the batteries stop holding a charge, you have to look for new batteries. Firstly, it is expensive - the price of batteries is up to 80% of the cost of a screwdriver; it is more efficient to buy a new tool. Secondly, batteries are not always on sale, for example, if a model is discontinued. Thirdly, a thrifty owner strives to use every opportunity to save money.

Converting a cordless screwdriver to work from an electrical network is a good solution. What does it give:

  1. The instrument gets a new life.
  2. No more batteries needing to be charged.
  3. The torque of the tool does not depend on the battery charge.

The disadvantage of the redesigned design is the dependence on the outlet and the length of the network cable.

Attention! Work at a height exceeding two meters with a converted screwdriver is not allowed.

How to convert a cordless screwdriver to work on a 220 Volt network

Craftsmen have come up with several ways to convert a screwdriver to work from an electrical network. They all involve providing the motor with the required supply voltage using an intermediate source or converter.

Connecting the screwdriver to the charger

Attention! At low voltage, losses in the wire are high, so the cable between the charger and the tool should be no longer than 1 meter, with a cross-section of at least 2.5 square meters. mm.

Sequencing:

    Solder or attach two wires with alligator clips to the terminals of the charger.

  1. Disassemble the old battery and remove the dead cells from it.
  2. Drill a hole in the battery case for the cable, thread the cable into the hole. It is advisable to seal the connection with electrical tape or heat-shrink tubing to prevent the wire from tearing out of the housing.
  3. Elements removed from the battery will disrupt the weight distribution of the screwdriver - your hand will get tired. To restore balance, a weight should be placed in the body - it can be dense wood or a piece of rubber.
  4. Solder the cable to the terminals of the former battery, connected to the screwdriver.
  5. Assemble the battery housing.
  6. All that remains is to test the updated tool in action.

Installation of a finished power supply in the housing of an old battery

Attention! In a closed case, the power supply is poorly cooled. It is recommended to make holes in the walls of the housing. Do not operate the tool continuously for more than 15 minutes.

Procedure:

  1. Disassemble the old battery and remove the non-functioning elements from it.
  2. Install the power supply into the battery case. Connect the high voltage terminals and low voltage terminals.
  3. Assemble and close the battery case.
  4. Install the battery into the screwdriver.
  5. Plug the power supply into the outlet and check the updated network tool in operation.

How to power a screwdriver while maintaining its autonomy

If the master works in a building that does not have electricity, and the batteries have already deteriorated, there are ways to power the screwdriver:

  • replace old battery banks with new ones;
  • connect the screwdriver to the car battery;
  • connect the tool to another battery, for example, taken from an uninterruptible power supply.

Replacing old elements

Attention! When replacing batteries, pay attention to the correct polarity of connecting the elements.

Procedure:


Attention! The converted battery should only be charged with a specially selected charger.

  • Connect the terminals. Try the tool in action.
  • Connecting to an external battery

    Sequencing:

    1. Buy or find an external battery, for example, take it from an unnecessary uninterruptible power supply.
    2. Take a wire with a cross-section of at least 2.5 square meters. mm. Remove the insulation and install clamp terminals suitable for mounting on the battery onto the copper ends.
    3. Place the other end of the cable in the body of the old battery and solder it to the terminals that are inserted into the screwdriver.
    4. Insert the battery case into the screwdriver, connect the cable with terminals to the battery.
    5. Test the restored tool in action.

    A cordless electric tool lasts several times longer than the batteries that power it. Throwing a screwdriver with unusable elements into the trash is unwise. The real owner will be able to repair the device by switching it to another power source, thereby giving it a new life.

    This idea was not born by chance. The fact is that on my model the engine sometimes stalled at high speeds. Patience ran out when the spring burst and the recoil starter cord eventually broke...

    To begin with, I purchased a gearbox for an internal combustion engine, which replaced the old manual starter...

    Well, directly the electric motor from the screwdriver

    But there’s a problem (there’s not enough space. I had to make a gearbox that would separate the electric motor from the gearbox on the internal combustion engine. I started by making a housing for this gearbox.



    .


    It may seem strange that there are so many gears, but I had to make such a “row” in order, as I already said, to move the electric motor away, due to lack of space. And the spacer between the plates was made of moisture-resistant plywood.


    And finally the result

    It’s a little shabby, so I decided to sand it with sandpaper)


    As you can see in the photo, a pin is installed on the drive shaft for engagement with the gearbox on the internal combustion engine.


    Now it's time to install this miracle on your car. I thought for a long time about how to do this. And here's what I thought...

    And finally everything is assembled...


    Although the model has become about 300 grams heavier)) But it starts upooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo300 grams-heavier the model are this model And + better grip!!
    And here is the video report:

    In the very near future I plan to connect all this to the 3rd channel. I will describe the details in the second part of the article... In the meantime, I am waiting for the arrival of the parts necessary to complete the project!

    Old electrical appliances tend to break down or not fully perform their functional duties over the years. In order not to throw away the old screwdriver, its parts can be used when assembling or making new and useful products for everyday life.

    When assembling a chopper using a screwdriver, such a device will work on the principle of a food processor.

    The algorithm of actions is as follows:

    • A hole is made in the bottom of the cone-shaped container into which the shaft will be mounted.
    • The container is placed on a wooden or metal stand.
    • Knives or blades are attached to a shaft inserted into the bottom.
    • Connect the power switch.
    • A hole is cut out on the side of the container and tubes are inserted into it to eject the already crushed processed products.

    Such a device will be a good helper in a country house or garden.

    To assemble the trimmer yourself you need:

    • Remove the motor from the screwdriver and attach it to the plug.
    • Pripyat the wires and stretch them through a pipe about 2 meters long.
    • Make a hole in the pipe and install the trimmer switch button into it.
    • Knives made from blades are attached to an electric motor.
    • The bottom of a plastic bucket is suitable as a protective visor.

    Note! To create a well-functioning trimmer, you need to take a motor with a power of at least 0.5 kW.

    A lawn mower, which is not cheap these days, can be obtained by removing the motor from a screwdriver and attaching it to a body with wheels using a method similar to the previous one.

    It’s easy to get a wind generator:

    • After disassembling a screwdriver with a power of at least 18 W, remove the electronic board from it.
    • Install a diode bridge.

    Note! The diode bridge makes it possible to rotate the wind generator blades in different directions.

    • A nozzle with blades is connected to the cartridge.

    This device makes it possible to charge batteries with a power of no more than 12 W.

    To get an angle grinder from an electric screwdriver, disassemble it, take out the gearbox and mount a special attachment using bolts and nuts.

    Such a device is much more functional than a factory angle grinder, but the rotation speed of the disk is several times lower than that of a professional one.

    Such a machine can be obtained if you fix a screwdriver with a drill in a vertical position on a moving bar. Install this structure on a horizontal stand or metal frame. The machine can be powered from electricity or a battery.

    By installing a screwdriver on a stand and attaching a grinding disc to it, you get an excellent homemade grinding machine.

    Lathe

    A lathe can be obtained if the screwdriver is fixed in a wooden stand and placed on a horizontal surface.

    Note! Such devices are suitable for amateur work, but not for professional needs.

    A hand generator is a device similar to a wind generator. The procedure for its manufacture is identical to the assembly of a wind generator. At the last stage of work, instead of an attachment with blades, a handle is attached to the screwdriver.

    Making an electric bike is easy:

    • Remove the motor from the screwdriver.
    • By connecting it to a bicycle sprocket.
    • Install the mechanism into the bicycle.

    Such a device for a child can be made from plastic pipes, fastened together with plastic ties, and a motor from a screwdriver can be used as a motor for a catamaran.

    This device is quite easy to assemble. To transform an old tool into a new one, you need to attach a metal cutting disk to a screwdriver instead of a drill.

    Instead of the motor, you need to install LEDs, observing the current strength, the flashlight is ready.


    Homemade products from screwdriver

    Broken screwdriver? Don't rush to throw it away. If you have golden hands, you are not a professional design engineer, in other words, you are just a fan of making something exclusive, if you have a child. a young technician or on weekends you get together with friends and don’t share the latest design thoughts, then a faulty screwdriver. It’s simply a godsend for your company.

    Try to use the main parts of the tool to do homemade products from a screwdriver. What might you need? First, this, this, the engine. Although, it’s natural to use everything, from the case to the battery, depending on the duration of the project and which parts are in good working order. The failure of the battery of a cordless screwdriver or other power tool is not the most pleasant event, especially when you consider that the cost of replacing this element is commensurate with. To come up with what is still directly do from a screwdriver - it’s better to use your imagination. If you are still new to design, now we can offer you several ready-made options so that homemade screwdriver were useful in, workers.

    What is needed, here is a concise list of what can come out of an old one screwdriver on the palms of a creative master:

    Those who have used a cordless screwdriver appreciate its convenience. Instantly, without getting tangled in wires, you can crawl into inaccessible niches. Until the battery runs out. This is the first drawback - it needs constant recharging. At some point, batteries will run out of charge cycles. This is the 2nd flaw. This popular rumor has finally arrived...

    And what can our inventive Kulibins, who have golden hands and a logical mind, come up with! You can successfully use the electric motor of a rusty washing machine and even adapt the parts of an ordinary household fan intended for disposal.

    Don't throw away your old screwdriver

    For example, the battery of a screwdriver has become unusable, but all other parts have become useless. Don't throw away the unit. It is in such cases that craftsmen make wind generators based on household devices, which, in this case, is an ordinary well-known screwdriver.

    Look at fig. 1, which shows a cross-section of an ordinary screwdriver. How can he be forced to start a new life from a completely different perspective? For the first part of its service to man, it took electricity to help with construction and repairs, and now it can be adapted to provide electricity using the wind.


    Disconnect everything unnecessary and remove the rotor part of the unit. Here is the engine shown in Fig. 2. Consider that this is a future windmill-invigorator, which will give you free electric current if you rotate it. The wind will spin. We clamp the motor shaft and strengthen it with a bracket (see Fig. 3 and 4). We drill four holes on the end gear and bolt to it a round steel plate for attaching the PVC pipe blades.

    We show the entire unit assembled and strengthened without blades. This is what the design of a homemade wind generator looks like, built on the basis of an electric motor from a screwdriver (see Fig. 5). In exactly the same way, you can assemble a wind generator based on an electric motor from a broken drill.

    So, we collected it. Now we need to reliably cover the entire mechanism from precipitation. There is a humorous saying: “The need for invention is cunning.” No wonder I remembered a popular saying that accurately conveys the resourcefulness of the technical mind of our craftsmen. To cover the mechanism of a homemade wind generator, some people used, you won’t believe it, an ordinary coffee can! (see Fig. 6). At the same time, a sealant was used to strengthen the lid and bottom of the jar on both sides, and the jar itself was wrapped with electrical tape.

    The result was a simple design like this (see Fig. 7). It remains to strengthen 4 blades cut from a PVC pipe, and a homemade wind generator based on household devices (drill, screwdriver or washing machine) is ready for work. If you want your homemade wind generator to be more efficient, use a gearbox from a wrench as a basis; it is much more powerful and produces more than 5 kW/hour.

    Use electric motors from household devices!

    Since we are talking about installing a wind turbine from household devices, it is necessary to note the following nuance. With all these devices, batteries or controllers usually fail, or rust eats away at the body. All other parts, including the electric motor, remain quite suitable for further service to humans. In this case, this unit can successfully operate as a generator.

    Look and imagine within the borders of any country how many old washing machines, screwdrivers and drills are lying around in landfills, attics, workshops and garages. At the same time, the free wind walks around like a hooligan, wasting its energy on pranks. Apply ready-made engines to wind forces - and you will receive free electrical energy for the same garages, workshops, and even ensure the operation of the radio and TV. Dare, invent, look for joy in everyday life every hour, every day - find it constantly. And you will find the happiness of a truly pulsating life!
