The presence of a screwdriver inspires many craftsmen to create additional devices and tools on its basis. The Kulibins' fantasy is endless. Equipment for the carpentry workshop - turning, drilling, milling machines, drill and grinder, power saw and wrench.

Even children's transport - electric cars and snowmobiles - does not stand aside. What can we say about the necessary devices in the household - trimmers and lawn mowers, and even an engine for a boat. The most amazing thing is that all of the listed "homemade products", made by hand, work on the basis of an ordinary old screwdriver and talented design solutions of home craftsmen.

Generator

The design of the screwdriver is such that a small improvement is enough to get electricity in field conditions. If you remove the board with the electronic regulator from the inside of the screwdriver and put a diode bridge at the output, this will allow you to turn the generator in any direction. It remains to clamp a homemade handle in the cartridge - the generator is ready!

Wind generator

Using a screwdriver motor, you can design a small wind generator for a summer cottage or a personal plot, and be independent of the power supply. And also he will help with a power outage in the network.

It will take a little time to create a wind generator. The rotor part is removed from the screwdriver. The motor shaft is braced to a plastic plate. We attach the flywheel to the end gear with bolts and attach four blades made of PVC pipe to it. For the case, you can use a tea can, carefully plugging the cracks with a sealant. The wind generator is ready to provide you with electricity that costs you nothing.

Carpentry equipment

Every joinery craftsman equips his workshop with the equipment necessary for his tasks. Not always a person for domestic use can afford expensive industrial production machines. And this situation is the impetus for the implementation of homemade products based on the available parts and tools.

Wood lathe

Wood lathe will become necessary tool for home craftsmen. Round blanks, door handles, spherical and conical fragments for wooden railings, chair legs and much more can all be made using a homemade screwdriver-based lathe.

You should not spend money on factory equipment if such a lathe can be easily made with your own hands from an old screwdriver using a minimum of funds and materials.

Briefly, you can describe one of these options for a "home-made" machine. A rectangular box (frame) is made of plywood with three sides. A landing nest is cut in the short side. A screwdriver is installed in this simple wooden frame, with the button up.

The bed, in our case a rectangular wooden box, is screwed to the table and pressed with a clamp. This is done in order to securely fix the bed together with the tool on the work table.

A wooden block is used as a support bar for the cutter, which is also screwed to the table with a clamp.

In the screwdriver's chuck, a piece of a bar with a thread that is convenient for hook is clamped. A piece of wood (blank) is pushed onto the bar. The screwdriver turns on and turns the wooden workpiece. With the help of a cutter, leaning on the support bar, the master cuts the desired volumetric detail.

The tool is essential for craftsmen who use wooden parts and fragments in their work.

Bench drilling machine

A bench drill is essential for many craftsmen in garages and workshops to accurately drill holes in wood, metal, plastic, etc.

Talented craftsmen do not spend money on purchasing production equipment. It takes a little effort and engineering skills, ingenuity and desire. As a result, you can get a solid design of a tabletop drilling machine from scrap materials.

The basis of the tool can be a gearbox from a screwdriver. The rod (rack) of the bed can be made by craftsmen from various materials. Everything goes into action: metal rods, typewriter carriages, wooden structures.

The mechanism for raising and lowering the gearbox vertically is also performed in a variety of ways. Even the springs from the expander are not superfluous.

To attach the gearbox to the bed rod, make homemade clamps from textolite, or use suitable parts from other devices or even cars.

Each design is individual and interesting in its own way. The main thing is that the task that is set for the drilling machine is carried out with the utmost accuracy and at the proper quality level.

You should not use broken and old screwdrivers for the machine, since the backlash in the chuck does not allow you to achieve the desired hole diameter.

Manual router: step by step instructions

If, when working with wood, you have the task of cutting a groove or a circle, you should not go and buy an expensive router. Having shown ingenuity, you can easily solve this problem and turn a screwdriver into a manual router by creating a lower frame with your own hands - a structure that would hold the tool vertically. Production attachments for milling for screwdrivers (drills) are on sale, but their purchase is not always financially justified.

The most readily available material at hand for a home craftsman is plywood and wooden blocks. Here we will make the attachment frame for milling from them, following the step-by-step instructions:

Let's make the bottom of the bed. Take plywood 8 mm thick and cut out a ring from it with an outer diameter of 10 cm, with an inner diameter of 5 cm. For this work we use a screwdriver with a "crown" for wood.
On the sides of this ring, screw two wooden bars 4x2x10 cm with self-tapping screws. Put the structure made with the bars up. This will resemble a stool with its legs up.
Let's make upper part bed. Cut another ring out of plywood with an outer diameter of 9 cm, and an inner one about 4.5 cm (to fit the size of the screwdriver body).
We fasten the upper part of the bed with self-tapping screws to the bars with the lower part.
We put the attachment-frame on the screwdriver body. It fits snugly into the round hole in the upper part of the bed.
Insert the required cutter into the chuck and adjust the cutter cut. We tighten the cartridge.

The manual router is ready. You can get to work!

The self-made design of the milling attachment described above - the bed for the screwdriver allows you to keep the tool off-weight and strictly vertical. A Bottom part the bed performs a supporting function when performing milling work.

Circular saw or grinder

The design of the screwdriver allows you to turn it into a circular saw (grinder). However, due to the low power of the screwdriver, this "circular saw" is rarely used for small jobs - to cut fiberglass reinforcement, a steel chain or a drill stuck in the ceiling for drilling concrete slabs, steel strips of small thickness.

A bolt, a nut and two washers allow you to clamp a small disc for metal work - that's all you need to turn the screwdriver into a grinder.

Of course, such an invention has the right to life, especially when the craftsman is unable to afford the entire range of industrial cutting tools.

Drill

A priori, each screwdriver can be used as a drill. Much depends on the power and function of the instrument. For example, impact screwdrivers combine the functions of a hammer drill, screwdriver and drill.

In such a situation, you should not go along the long path if there is a short one. It is enough to get a screwdriver out of the screwdriver chuck and insert the drill. Switch the operating mode to "drill".

Children's vehicles

Creation of children's Vehicle moving without physical effort has always been and remains a fascinating task for men who like to tinker with a tool in their own garage or workshop. Of course, it is worth noting that some of these cars require adult control in order to avoid collisions, injuries and various troubles “on the road”.

Electric car

How to stay indifferent to a passing small car? Such "homemade transport" will interest both adults and children.

What kind of cars do not create the talented hands of our craftsmen. They use PVC pipes, gears from motorcycles, wheels from a garden wheelbarrow, frames from a bicycle. Surprisingly, all these not very necessary parts turn into a wonderful "adult" toy.

There are various designs - three-wheeled, four-wheeled, made of metal, wood, plastic. The driving mechanism of all these little cars has the same tool - a screwdriver with a battery.

The screwdriver transmits torque to the rear-wheel drive wheels through a chain drive (a large sprocket on the wheel and a small drive sprocket on the screwdriver shaft, a chain from a bicycle). The screwdriver turns the leading small sprocket, through the chain, the twisting movement is transmitted to the large sprocket, and from it to the rear-wheel drive wheel. Thus, the rear wheels push the front wheels and the car moves.

On-off control is output to the pedal by means of a button, which is pressed by the pedal lever. A small push of the foot is enough - the button is pressed and the "vehicle" is set in motion!

Electric scooter and electric bike

It is difficult to deny a child the pleasure of riding a scooter. But what will be the surprise and happiness when he sees this scooter in an improved, or rather in a "self-propelled" form. No physical effort is required to ride. Only a smooth road and balanced movement.

So how do you make an electric scooter with your own hands, while spending a little money? The options may vary. They are united only by the fact that the source of movement, the motor is a screwdriver.

The structural part can be made individually, from an old overcooked bicycle with an extended handlebar or from a scooter. But the most important thing in an electric scooter is the propulsion part.

Let's summarize the principle of its operation. There is a leading sprocket, inside which the rod is hammered. This rod is installed in the chuck of the screwdriver.

The screwdriver turns the drive sprocket, which, through the chain, transfers rotation to the second sprocket mounted on the wheel. What could be easier? How to attach a screwdriver to a bicycle, each craftsman decides differently. It all depends on the possibilities and imagination.

The on-off system is displayed on the steering wheel. Many different solutions have been invented for this: cable systems, hydraulics from a hose and two syringes. Everything in order to turn on or off the screwdriver with a handle or a button on the steering wheel. It makes no sense to list those and delve into their technical features, let it remain the prerogative of motorists.

Electric snowmobile

How much fun winter days bring to children! Skis, skates, sleds. How many times do kids ask adults to ride them on a sled? It is difficult to deny children such a pleasure. Domestic craftsmen approached this issue more thoroughly and made the sled "self-propelled".

All that is needed for this is a source of torque. This source, or rather the base, will be a screwdriver with a working battery.

First, the iron construction of the "sleigh" itself is selected. It can be a real sled with steering. Or maybe homemade products that are installed on frames and also have a handlebar, sometimes a bicycle one. But be sure to install a handle on the steering wheel, which will serve to turn the engine on and off. Outwardly, it will look like the brake handle on a sports bike.

Since home craftsmen come up with different designs of snowmobiles, the systems for attaching a screwdriver to an iron platform are also different. Only by generalizing it is possible to bring together the principle of installation and action, which looks like this. On the back of the sled, a wheel is installed using a special metal structure, and a screwdriver above it. In fact, a screwdriver gives a torque to the wheel through a system of two sprockets and a chain. The screwdriver shaft rotates the drive sprocket. The sprocket transmits the rotational motion through the chain to a second sprocket that is mounted on the wheel. Thus, the screwdriver makes the wheel turn and push the sled.

It remains only to bring the control system to the steering wheel. The control is a cable system, one end of which is connected to the power button of the screwdriver, the other is attached to the handle on the steering wheel.

By squeezing and squeezing the handle, we turn on and off the screwdriver mechanism.

Of course, it will take effort and time to cope with such a job. Purchase a sled or base material, the cordless screwdriver itself. But the efforts that you make will more than pay off with childish joy and those emotions that cannot be described in words and are not calculated in monetary terms.

Use in the garden

We are part of nature. How harmoniously each of us feels in the garden, at the dacha or in the personal plot. An evenly mowed lawn, weeded beds delight our eyes. However, it is very difficult to achieve such a result manually. An aching back, fingers cut by grass can be excluded from your life if you apply ingenuity and use the most primitive tools to design a garden trimmer, or a lawn mower, as we are used to calling this tool.

It is very easy to make such a trimmer. For this you need:

Cordless screwdriver;
Body polishing disc;
Two stationery blades;
Two screws.

It literally takes a couple of minutes to create a tool. Two clerical blades are screwed onto the body polishing disc with screws. Only they are screwed on not rigidly, but so that they can easily "dangle". This type of connection allows the blades not to break, but to lay when in contact with an obstacle. The disc itself with the blades already attached is installed in the screwdriver, naturally with the cutting tool down. The tool is ready to go!

Such an amateur trimmer will allow you to mow the grass in hard-to-reach, narrow places, in the aisles or where there are partitions. Of course, the undoubted "plus" is the savings in time and effort that you spend on manual weeding. There are only two drawbacks - you still have to bend over and cut the grass in this position, and then pick it up by hand.

There are also specific features. With high grass such a tool, you need to "fight" in a special way. Cut off the top first and then the base, as long grass can get tangled at the base of the disc. Then it must be removed manually.

Of course, in comparison with production-type lawn mowers, trimmers and shredders, such a tool looks amateurish. But a "little helper" is better now than grandiose plans to buy an expensive lawn mower in the future ...

Boat motor

How pleasant it is to ride a boat in warm summer weather. One bad luck - I don't want to take the oars in my hands. Savvy comes to the rescue.

But what if we adapt the motor from a screwdriver to the boat using the tools at hand?

What is easier to apply the following materials for this "idea":

Screw (rabbit):
Long metal hairpin;
Battery-powered screwdriver.

The essence of the idea is as follows. In the rabbit (in this situation, the propeller), drill a hole in diameter equal to the metal hairpin. The screw is mounted on a stud and is securely fastened. The longest pin itself is inserted into a screwdriver, which turns the pin along with the screw. The boat engine is ready!

All that remains is to come up with some kind of metal structure that will allow you to securely fix the screwdriver on the boat itself. But this is too easy a task to discuss. And every amateur will be able to show their inventive abilities in this matter.

We lower the screw on the hairpin into the water and turn on the screwdriver. All that remains is to sail slowly and enjoy the beauties of nature that you see around. There is only one thing - really assess the capabilities of the batteries and "do not swim for the buoys."

Conclusion

Do not limit the fantasies of craftsmen! Thanks to their ideas and talented hands, old technology not only gets a new life, but also improves the quality of our work and leisure.

In shaggy 1997, dad brought a good-quality cordless screwdriver from a trip.

Since then, the machine has helped to unscrew an unmeasured amount of Ikea furniture, hang a lot of paintings and photographs on the walls, etc., and so on. The assembly was modestly derived from Made in USA; this is not China today.

Already the Deutschmarks for which the machine was bought were no longer in circulation, and it went into its second decade - and the age still took its toll, the capacity of the batteries dropped sharply. I went shopping, made sure that either the frank Mr., or Bosch with Makita for indecent money is on the shelves, and I was upset.

An autopsy showed that the screwdriver contains 12 Ni-Cd SubC batteries. Ali did not find such a non-standard, but there were several sellers on eBay who had them. Immediately arrived in time. As a result, the batteries were taken from the vendor who had a lot with a suitable number of batteries. Including eBay, the batteries cost me a ridiculous $ 2.88 for the entire dozen.

The item was purchased on November 9 and without track. numbers arrived from Hong Kong to Moscow only on December 21 - the new year is affecting. The package was in a tight envelope and a "bubble wrap" and at first aroused the desire to write an angry review to the seller.

How wrong I was, I was convinced by killing at least a quarter of an hour to unpack: the batteries were soldered in pairs with a dense film, each contact was in a dense shrink film:

The screwdriver used to have 1200mAh batteries, the new items turned out to be 2500mAh, moreover, they arrived immediately charged:

(there is no actual capacity of the desire to recheck, and there is nothing special, from the equipment I only have a multimeter ..)

Soldering experience I have - for a three with a minus, and I immediately realized that I had nothing to catch here, it would not work to solder the elements consistently, ordinary solder would not hold on to such surfaces. Rescued "classic of Taj-repair" - a hot glue gun. With its help, it was possible to fix all 12 elements in the desired sequence and tightly close the conclusions to each other. Since batteries live in a screwed box, such an installation is quite reliable:

The battery leads were thin, but extremely durable. Holes are punched at the ends in case you need to attach a wire to them.

As a result, for about 100 rubles old faithful helper healed new life, and I saved on buying a new Bosch. The game is definitely worth the candle, so if you have an aging machine, feel free to experiment.

P.S. Do not throw used cadmium batteries in the trash! Cadmium is still a poison, it is good at getting into groundwater and dissolving there. It is better to hand over the used ones to the same place where used car batteries are accepted.

When the batteries stop working, many people wonder how you can convert a cordless screwdriver into a network one. It is impossible to repair batteries with damaged cells. The cost of new power supplies is almost equal to the price of a screwdriver. It is not always possible to find suitable elements, models are often taken out of production. But for zealous and skillful owners there is a way out - to power the screwdriver from the mains.

Power supply for the screwdriver - 2 main options

There is only one drawback of the converted instrument: it is tied to an outlet. But for indoor work, this is not so essential. But there are more advantages. Now you don't have to worry about recharging the battery, there will be no downtime. The current strength remains stable all the time and does not depend on the discharge of the battery, which means the constancy of the torque.

Before you go in search of a power supply unit (hereinafter referred to as a power supply unit), study the parameters of the screwdriver, which are indicated on the case or in the passport. Pay attention to the voltage. A 12-volt instrument is more common, it is not difficult to find a power supply for it. If the tension is greater, the search may be delayed. It is required to find out the consumed current, which is not indicated in the technical specification. The purchased unit should produce an average current value (between the battery capacity and the standard charger). The data can be found from the label.

There are two main options for converting a 220 volt cordless screwdriver. The first is to use an external power supply unit. Any rectifier capable of supplying the required DC voltage will do. Even if it is large and bulky, there is no problem. After all, you don't have to carry it around the room. The unit is installed near the outlet, and the cord to the tool is made of the required length.

Remember that with decreasing voltage, the amperage increases if the power remains the same. This means that the cross-section of the low-voltage cord must be larger than that from the 220 V.

The second option is that the PSU is mounted in a battery case. The only obstacle in choosing this method may be the size of the transformer. Mobility is maintained, the radius of use depends on the length of the power cord. It is important to remember that the instrument is supplied with 220 V power, so the cord must be reliable, and the entrance itself is made neatly, carefully insulated.

Which external units can be used - an old computer or a laptop charger?

Available power supplies can be used as an external source:

charger for car batteries;
PSU from an old computer;
charging from a laptop;
homemade PSU.

You can buy an old charger on the market inexpensively. Pulse chargers are now mainly used, and old devices are often sold as unnecessary. It is such a charger with the ability to manually adjust the voltage and current that is ideal for any screwdriver, regardless of its operating voltage. The whole alteration consists in connecting the low-voltage cord to the output contacts of the charger.

The computer power supply is purchased from older models and must have a shutdown button. You will not need it, but this is exactly the version of the "AT" format that you need. On the radio market, a block with a capacity of 300-350 watts is selected, which will ensure reliable operation of low-power and medium-sized screwdrivers. Everything specifications are indicated in a sticker on the case. The unit has a cooling fan and overload protection. To convert a computer power supply unit with our own hands to an external one for a screwdriver, we perform simple operations:

disassemble the case;
on a large square connector we find a green wire and any black one;
we connect both wires to each other, insulate;
on the other smaller connector, remove all the wires, leaving yellow and black;
we solder the cable cord to them.

To observe the polarity, you should know: yellow wire - positive, black - negative ... An instrument with a voltage of up to 14 volts works from a computer power supply.

Most laptop chargers have characteristics that allow them to be used as a power source for a screwdriver. Chargers with an output voltage of 12-19 volts are suitable. The only changes that need to be made are related to the output plug. Cut it off, strip the wires and solder a cable of the required length to them.

Individuals with an understanding of electrical engineering can make a homemade power supply. Its circuit is quite simple and includes a step-down transformer, a diode rectifier and two capacitors. All parts can be bought or taken from old radio equipment. A transformer from a tube TV with an output of 24-30 V. A rectifying diode bridge is required. Capacitors are used not in short supply, from old technology: one for 0.1 microfarads and the other electrolytic for 4700 microfarads.

Attention! The structure must be enclosed in a housing. To protect against short circuits, it is mandatory to install fuses at the input and output.

How to place a PSU in a case - 3 different possibilities

The mains can be placed in the battery case or in the handle. Possible options:

any PSU suitable in terms of characteristics and size;
Chinese power supply unit for 24 V;
homemade.

On the radio market, a power supply unit with the necessary parameters is selected. At home, it should be carefully removed from the case and placed in your screwdriver, securing all components securely. If the wires are short, lengthen them so that they do not touch metal parts. Place the transformer and the board separately. Install additional heatsinks on microcircuits for better cooling. Also, the holes in the case will not be superfluous so that air circulates and heat is removed during operation.

In a radio parts store, we buy a power supply unit for 24 V, current 9 A. Screwdrivers operate from 12 or 18 Volts, so the task is to lower the voltage to the required level. To do this kind of work, a minimum knowledge of radio engineering is required. The output voltage is maintained by a 2320 ohm resistor R10. A 10 kΩ trimmer should be installed instead. How to configure the power supply is described below:

solder the permanent resistor;
set the resistance of the trimmer resistor to 2300 Ohm for the device;
solder the trimmer resistor in place of the constant;
when the power supply unit is on, adjust the voltage.

The design of a homemade power supply unit will be based on an electronic transformer. Feron or Taschibra at 60 watts. These can be purchased at an electrical store and are designed for halogen bulbs. They do not require any alteration. Tapping the secondary winding from the midpoint made it possible to use two Schottky diodes instead of the usual four. The operation of the power supply unit is monitored by the HL1 LED. The diagram shows all the necessary details.

The T1 transformer is self-wound. A non-deficient ferrite ring НМ2000 with a size of 28 × 16 × 9 is used. Before winding with a file, the corners are cleaned, the ring is wrapped with FUM tape. The block made is mounted on an aluminum plate with a thickness of 3 mm or more, placed in the battery case. It also serves as a common wire.

How to Install Correctly - Do you need a counterweight?

Reliability in operation and safety depend on the reliability of the installation of the electrical part. A soft stranded cable is used as a mains and low-voltage cable. If the device is external, connect the ends of the cable to its terminals. We treat copper wiring and brass contacts with soldering acid, after which they are easily soldered. In practice, special clips are often used - "crocodiles". In the screwdriver itself, soldering is indispensable, the "crocodiles" do not hold so strongly that the contacts do not separate during operation.

Ideally, use an old battery case. It is disassembled and the entire interior is removed. At the same time, harmful substances are released, care should be taken to protect respiratory tract and skin. The body is washed with a soda solution, running water and dried. From the inside of the contacts, we solder the ends of the cable, observing the polarity. In order not to guess, we temporarily connect the cable, turn on the screwdriver and look in which direction the spindle rotates, mark the wires. We make a hole in the lower part of the case, let the wires pass. Inside the case, the cord should be securely fixed by wrapping insulating tape around it. This thickening will prevent the wiring from pulling and breaking. Then we solder the ends to the contacts.

We place a counterweight inside the body. The best material is molded rubber. It has the necessary characteristics: high density, insulating properties. To prevent the rubber from dangling inside, we cut it out with a slight overlap. To place the counterweight in the body, bend the material a little and place it so that it does not vibrate and serves as additional insulation. Perhaps some counterbalance will seem superfluous, but it is not. The design of the screwdriver provides that the center of gravity is in the handle. This puts stress on the hand, but relieves the hand. When the batteries are removed from the body, the center of gravity shifts, increasing the load on the hand. It becomes uncomfortable and difficult to work. The homemade counterweight restores the center of gravity close to the factory one.

How to use a cordless screwdriver - simple rules

You have seen how easy it is to convert a cordless screwdriver into a network one. The practice of craftsmen suggested simple and useful tips for operation:

after 20 minutes of work, give the screwdriver a five-minute rest;
fix the electric cable on your hand so that it does not interfere with your work;
the power supply unit should be regularly cleaned from dust;
do not use extension cords to connect the power supply to the network;
The power supply unit must be grounded;
Do not use power screwdrivers at work at height.

Compliance with these rules will extend the life of the updated instrument. Mobility is a little lost, but the unit does not require recharging, it works smoothly and confidently.

Everyone is familiar with the screwdriver. This is a hand-held power tool designed for twisting and unscrewing a variety of fasteners. This is the main direction of its application, but not the only one. With the help of a screwdriver, you can create a great variety of useful and necessary things.

Screwdriver as a generator

The screwdriver can be used as a generator. This is very easy to do. It is necessary to remove the battery, connect the wires to the terminals using crocodiles and connect them to the consumer. Be sure to first check the polarity with a multimeter. Insert and tighten the hex key into the chuck to assemble the furniture. By rotating the spindle, a current will be generated, which will be supplied to the consumer. True, it is worth noting that the voltage generated by this electric machine is only enough for charging mobile phone or the work of a small LED lamp.

Using wind energy with a screwdriver

According to this principle, wind generators are built from a screwdriver, but the generated current is so small that the game is not worth the candle. Its installation is more effective in areas of high wind load, although the result does not justify itself there either.
