How to make a networked screwdriver?

Rechargeable screwdriver – the necessary thing in the farm, the main advantage of which is his mobility. However, with long work, the tool requires regular recharging, which is very uncomfortable. In addition, old accumulators fail, and buy new is obligated or even impossible because the model can be removed from production. Rational decision – to build a permanent power supply for a screwdriver.

Advantages and disadvantages

Before starting work, you should evaluate all the pros and cons of modernization of the tool from the battery in the network. The main drawback is the loss of mobility, which is not always convenient to work at height or far from the outlet. As for the advantages, several positive factors can be allocated here:

  • disappears the problem of suddenly discharged batteries;
  • stable torque;
  • There is no dependence on the temperature regime (at low values, the batteries are discharged faster);
  • Saving funds for the purchase of new batteries.

The modernization is especially relevant when “native” batteries failed, and new or not on sale, or they need to go far. It also happens that the purchased apparatus has some problems when receiving energy from the battery. It may be marriage or shortcomings of the model. If in principle the tool suits, it is advisable to remake it and exercise the network.

Power source options

Since the screwdriver requires voltage much lower than in a centralized network, an electrical adapter is needed for a network tool – a power supply unit that will convert 220 volts of variable to 12, 16 or 18 volts of constant value. There are several power source options.

Pulse

Pulse apparatus – inverter system. Such power blocks first straighten the input voltage, then convert it to high-frequency pulses, which are supplied either through a transformer or directly. Voltage stabilization due to feedback is achieved in two ways:

  • due to the output transformer winding in the presence of sources with galvanic junction;
  • With the help of a regular resistor.

Experienced masters prefer a pulsed power supply, since it is small. Compactness is achieved due to the absence of a power transformer.

Such a power source, as a rule, has a fairly high efficiency – about 98%. Pulse blocks provide short-circuit protection than ensuing the safety of the device, as well as blocking in the absence of a load. Among explicit minuses, the main thing is lower power compared to the transformer option. In addition, the action of the device is limited by the lower limit of the load, that is, with the power below the allowable level, the power supply will not work. Users also note an increased level of complexity of repair compared to the transformer.

Transformer

Transformers are considered a classic power supply option. Linear power source is a symbiosis of several components.

  • A step-down transformer. Silent winding is designed for voltage.
  • Rectifier whose function is to convert the AC network to a permanent. There are two types of rectifiers: single-alpapid and bippetier. As part of the first 1 diode, in the second – diode bridge from 4 elements.

Also, the scheme may include other components:

  • a large capacitance capacitor required for smoothing pulsations, located after a diode bridge;
  • stabilizer that causes constant output voltage, despite any jumps in the external network;
  • Protective block from short circuits;
  • High-frequency filter to eliminate interference.

The popularity of transformers is due to their reliability, simplicity, repairs, absence of interference and low cost. Among the disadvantages, only bulky, high weight and low efficiency. When choosing or self-assembling transformer power supplies, it should be borne in mind that the output voltage should be slightly higher than the tool required for operation. The fact is that its part is closed by the stabilizer. For example, for 12 volt powered screwdriver, a transformer power supply with a voltage value at an output of 12-14 volts.

Specifications

When buying or self-assembling the power supply always repel from the necessary technical parameters.

  • Power. Measured in watts.
  • Input voltage. In domestic networks 220 volts. In other countries of the world, this parameter is different, for example, in Japan 110 volts.
  • Output voltage. The parameter required for the operation of the screwdriver. Typically varies from 12 to 18 volts.
  • Kpd. Reflects the efficiency of the power supply. If it is small, then most of the converted energy goes to heating the housing and tool parts.

Necessary materials and tools

In the work on the modernization of the accumulator type You can use the following tool set:

  • screwdrivers of different types;
  • Passatia;
  • nippers;
  • construction knife;
  • insulation in the form of a tape;
  • electrical cable (better stranded), wire for jumpers;
  • soldering station, including soldering iron, solder and acid;
  • Cabinet for power supply, which can act as an old battery, factory ready-made device, homemade box.

When choosing a box, you need to consider the size of the structure of the power source so that it places inside the device.

How to remake with your own hands

In order for a screwdriver to work from a network with a voltage of 220 volts, it is necessary to build a power supply that issues 12, 14, 16 or 18 volts at the output, depending on the tool model. Using the available battery charger case, you can make a network charging, performing actions in the following sequence.

  • Determine the size of the housing. Network block need to make this size so that it fit inside.
  • Multi-sized sources are usually placed in the housing of the screwdriver. To do this, you need to disassemble the battery and remove all the insides. Depending on the tool model, the case is collapsible or glued. In the last version you have to open the tool on the seam.
  • Using the labeling, we determine the voltage and current strength. As a rule, manufacturers do not indicate the last parameter, but instead it is present such as power, or full electric load, expressed in watts. In this case, the strength of the current will be equal to the private from the fifth of power to the electrical voltage.
  • In the next step to the carts of the charger, you need to solder electrically. Since the terminals are usually made of brass, and the veins are made of copper, fulfill this task difficult. For their compounds, a special acid is used, which is treated with a brass surface before soldering.
  • Reverse ends of the wires are connected to the battery exit. An important point is the observance of polarity.

Of course it would be easier to connect to the network directly using a fork and outlet. However, in this case, the device will refuse to work. First, because it is designed for constant slight tension, and in the network variables and large. Secondly, so safer. Elements for electrical circuit (diodes, resistors and t. NS.) You can buy, and you can borrow from unnecessary household appliances, for example, from an energy-saving lamp. It happens that the power supply is more expedient to make it completely with your own hands, and sometimes it is better to buy ready.

Homemade block

The easiest way to assemble the charger is to use the housing from the native battery, which came into disrepair. In this case, there will be a Chinese 24 volt power supply unit for internal filling, or some ready-made BP, or the power source of its own assembly. The beginning of any modernization – electrical circuit. It is not necessarily drawn by all the rules, enough from hand to portray the sequence of connecting parts. This will allow you to identify a number of items necessary for work, and will also help avoid mistakes.

Alteration of Chinese production

Such a source is designed for the output voltage of 24 volts. It can easily be bought in any outlets with radio components, it is available at a price. Since most of the screwdrivers are calculated on operating parameters from 12 to 18 volts, you will have to implement a scheme that reduces output voltage. Make it pretty easy.

  • First of all, the R10 resistor should be dropped, which has a constant resistance of 2320 ohms. It is responsible for the magnitude of the output voltage.
  • Instead, an adjustable resistor should be soldered, having a maximum value of 10 com. Since the power protection is built into the power supply before installing the resistor, it is necessary to install resistance on it equal to 2300 ohms. Otherwise the device will not work.
  • Next, electricity is supplied to the block. Multimeter define the values ​​of the output parameters. Do not forget to measure the measuring device for the range of constant voltage.
  • Using adjustable resistance achieve the required voltage. By using a multimeter, you need to check the current for the current does not exceed 9 amps. Otherwise, the re-equipped power source will fail, as there will be great overload.
  • The device is fastened inside the old battery, having previously removing all the insides.

Alteration of purchased blocks

Similarly, the Chinese device can be embedded in the battery box and other ready-made power supplies. They can be purchased at any radio component store. It is important that the selected model is designed to work with a 220 volt network and had a suitable operating voltage. Modernization in this case will be implemented as follows.

  • First disassemble the purchased device.
  • Next, convert the design to the necessary parameters is similar to the reconstruction of the Chinese power source described above. Religent resistance, add resistors or diodes.
  • The length of the connecting wires should be chosen on the basis of the dimensions of the battery compartment of the power tool.
  • Carefully Isolate Speeded Places.
  • Fee is better equipped with a radiator for cooling.
  • Transformer is more expedient to place separately.
  • The collected circuit is mounted inside the battery compartment and fix. For reliability, you can glue.
  • Attach an electric cable taking into account polarity. All conductive parts should be isolated in order to avoid short circuit.
  • In the case you need to drill a few holes. One thing – under the output of the electrocabolic, others – to drive hot air to ensure circulation and reduce the degree of heating the screwdriver during operation.
  • Upon completion of the work check the functioning of the device.

From computer BP

As a rule, the craftsmen use at-type blocks. They have the power of about 350 watts and the output voltage of about 12 volts. These parameters are enough for normal operation of the screwdriver. In addition, all specifications are indicated on the housing, which greatly simplifies the operation to fit the power supply to the tool. The device can either borrow from the old computer, or buy in a computer salon. The main advantage is the presence of a toggle switch, cooling cooler and a protective system from overload.

Next, the sequence of actions is the following.

  • Disassembling computer block case.
  • Liquidation of protection against inclusion, consisting in connecting green and black wires that are present in the specified connector.
  • Work with Molex connector. It has 4 wires, two of which are not needed. They must be cut off, leaving only yellow by 12 volts and black – grounding.
  • Shipping to left wires of an electrical cable. Special attention should be paid to isolation.
  • Disassembly screwdriver.
  • Connection of the tool terminals with the opposite end of the electrocable.
  • Assembling tool. It is necessary to monitor the cord inside the case of the screwdriver not twisted and is not very pressed.

As a lack, you can highlight the fitness of such a power supply only under the tool with an operating voltage not higher than 14 volts.

Laptop Charger

Power supply for a screwdriver can be a laptop charger. His refinement comes down to a minimum. It should be noted that any device for 12-19 volts will be suitable for use. Algorithm of actions Next.

  • Preparation of the output cord from the charger. With the help of bruises, the connector is cut off and the ends are cleaned with insulation.
  • Disassembly of the tool housing.
  • The bare ends of the charger solder to the terminals of the screwdriver, observing the polarity. You can use special plastic screeds, but professionals are advised not to neglect soldering.
  • Isolation of compounds.
  • Assembling power tools.
  • Testing for performance.

Alteration of the finished charger is easier and accessible to everyone.

Car battery

An excellent option for powering the screwdriver is a car battery. Especially in cases where the repair is required in the area devoid of electricity. The negative point is that it is possible to power the tool from the auto accumulator only for a short time, since the vehicle risks to discharge and will not move off. For the launch of the screwdriver sometimes rewor the old car battery of analog type. Such device is characterized by manual power control and output voltage.

Instructions for modernization.

  • At the first stage, you should choose a couple of stranded cables. It is desirable that they were in the winding of different colors for the difference, but one cross section.
  • On the one hand, contacts are fixed in the form of “crocodiles”, on the other, the insulating layer is cleaned with 3 centimeters.
  • Bare ends bend crochet.
  • Next, proceed to the wake of the casing of the screwdriver.
  • Find contact terminals with which the tool connected with the battery. The bent stripped cable ends are soldered to them. You can do without soldering, taking advantage of special plastic screeds, but professionals prefer the soldier.
  • Connections should be thoroughly isolate, otherwise there is a risk of a short circuit.
  • Both ends of the cable neatly fit inside the housing and outwardly outward through the handle. Perhaps you will have to drill additional holes for this.
  • Next should be collected tool.
  • After all manipulations, the device is tested. With the help of “crocodiles”, the screwdriver is connected to the car charger, observing “+” and “-“.

Precautionary measures

When working with any electrical device that has undergone upgrades, Certain safety rules should be followed.

  • First of all, when reworking, in no case should be neglected to neglect the good insulation of contacts and grounding.
  • For a screwdriver, short-term breaks are needed every 20 minutes. In the redistribution, the technical characteristics were changed, which were laid by the manufacturer and were designed to work from the battery. Increased power led to an increase in the number of revolutions, which causes the heating tool. Small respite will extend the operating time of the screwdriver.
  • The power supply is recommended to be regularly brushed from dust and dirt. The fact is that when modernizing the tightness of the case was broken, therefore pollution and moisture falls inside, especially during open-air operation.
  • Electrocabel can not be twisted, stretch or press. Be sure to track so that it does not undergo any negative impacts during operation, which may cause closure.
  • Experts do not advise use homemade network screwdriver at a height of more than two meters. As this automatically entails the tension of the wire under its own weight.
  • When setting up output parameters, you need to choose a current of 1.6 times more than battery power.
  • It should be known that when the load is submitted to the device, the voltage may decrease from 1 to 2 volts. In most cases, this is not fundamentally.

How to make a networked screwdriver?

These simple recommendations will extend the service life of the screwdriver and protect its owner from trouble.

As practice shows, self-alteration of the power supply requires experience and good theoretical knowledge on electrical engineering. Therefore, before choosing, it is necessary to decide whether you are ready to spend your free time for drafting a circuit, assembling the power source, especially in the absence of due skills. If there is no confidence, then experts advise to buy ready-made chargers, especially since their value in the market is low.
