What Can Be Done From A Broken Screwdriver

Conversion of a screwdriver from battery to mains supply
If your cordless screwdriver is out of order, it is not necessary to look for a new battery for it. You just need to convert it to network! Step by step instructions in our material.

Battery case power supply

Mobility remains, you are limited only by the length of the network cable. The only problem is how to squeeze a sufficiently powerful transformer into a small case.

We recall Ohm’s law again, and understand that a powerful 220 volt electric motor can be compact.

We build in a ready-made power supply

To do this, you need to purchase a ready-made block with suitable characteristics and dimensions. There is enough of such stuff on the radio markets.

Take the body with you and go to the fitting. When the required power source is purchased, we carefully separate it from the case.

what can be done from a broken screwdriver

We place the screwdriver in the battery box. All components must be securely fastened.

If necessary, extend the wires between the control board and the transformer. If the circuit touches the metal parts of the transformer during operation, a short circuit will occur.

Since the space in the case allows. Separate the board and the transformer for better cooling. Whichever quality power supply you choose, the load will be high and overheating is possible.

It will not be superfluous to fix additional radiators on the power control microcircuits. Operate the screwdriver for a long time, disconnect it from the mains and touch the radio components on the control board.

You yourself will understand which elements need heat dissipation. Holes for air circulation can be made in the housing.

Redesigning the power supply unit with your own hands will not take much time, and the cost of the purchased module is incomparable with restoring the battery’s performance.

Battery Disadvantages

  1. Needs regular recharging. Sooner or later, batteries will use up their cycle life.
  2. The cheaper the tool, the faster the rework time will come.

There is nothing wrong with that, but you should be aware that the manufacturer saves as much as you do. Consequently, the most expensive unit (namely the battery) will be the cheapest when bundled.

As a result, we get an excellent tool with a serviceable motor and not a worn gearbox, which does not work due to a poor-quality battery.

There is an option to purchase a new set of batteries, or replace faulty batteries in the unit. However, this is a budget event. The cost is comparable to buying a new screwdriver.

The second option is to use a spare or old battery from the car (if you have one). But the starter battery is heavy, and using such a tandem is not very comfortable.

External power supply

The idea is not as absurd as it might seem. Even a large and heavy buck rectifier can just stand near the outlet.

You are equally tied to the power supply, and to the stuck mains plug. And the low-voltage cord can be made of any length.

Important! Ohm’s law says. With the same power, decreasing the voltage. We increase the current! Accordingly, the 12-19 volt supply cord should have a larger cross section than 220 volts.

Mobility remains, you are limited only by the length of the network cable. The only problem is how to squeeze a sufficiently powerful transformer into a small case.

There is a way out. Reworking the screwdriver in the network

Yes, it loses one of the benefits of a cordless tool. Mobility. But for work in rooms with access to a 220 volt network, this is an excellent way out. Over, you give new life to a broken instrument.

There are two concepts of how to make a network out of a cordless screwdriver:

Manual router from a screwdriver: step by step instructions

It can be converted into a hand router. You do not need to purchase expensive materials for this. Everything you need can be found in the workshop or garage almost under your feet. To equip a hand router from a screwdriver, you will need pieces of thick plywood or chipboard, a clamp for attaching a tool, fasteners in the form of bolts and self-tapping screws, a locksmith’s tool and a feather drill for wood. In the latter case, you can use a drill bit.

Assembling a homemade router is pretty easy. This requires:

  • From the pieces of the selected material, cut out the base, the vertical stand, on which the screwdriver, the stop and the gusset will be fixed with the help of the clamp to make the structure rigid. The dimensions of the parts are chosen arbitrarily, in relation to the dimensions of the power tool.
  • Drill a Ø 40 mm hole in the base using a feather drill for free access of the cutting tool to the processing area.
  • Make a clamp to the diameter of the hand tool.
  • Fix the screwdriver on a vertical stand with a clamp so that its cartridge is at a distance of several millimeters from the base.
  • Install stiffener.
  • Fix the screwdriver on the vertical stand with a stop.
  • Insert the cutter into the tool holder.

The screwdriver router is ready to use. Such a machine will not be able to become a full-fledged replacement for a hand mill due to its low power and low spindle speed, but it will solve the issue of milling small parts in a home workshop.

Bench drill

Drilling is another equally important equipment. It can also be made from a screwdriver. To do this, you will need a used screwdriver. From it you need to take a motor with a gearbox and a cartridge. Now you need to make two clamps of PCB, which will perform the function of fixing the drill head of the machine. To achieve maximum alignment of all the holes on the clamps, it is better to process them together, in one set. Then it will be possible to avoid distortions.

Bushings with internal threads are used as limiting struts. They must be the same size, corresponding to the distance between the clamps. After that, another clamp is made of PCB and two bosses of caprolon. They are drilled off-center to form two eccentric bushings. The clamp is installed on the bar and with the help of eccentrics the backlash is selected. After that, a wooden lever is installed on a spring so that the drilling head returns to its original position. To supply power, it is necessary to use a transformer with a capacity of more than 150 watts and an output voltage similar to the used screwdriver. After that, you need to put a diode bridge and a capacitor, install the drilling head on the bed.

Electric snowmobile

With the help of a screwdriver, you can make not only transport on wheels, but also a real snowmobile. You need to use an electric car for this, having carried out a number of appropriate upgrades. It is necessary to improve the frame of the electric vehicle to install the drive wheel on it. Instead of driven wheels, you need to install skis, replace the plastic steering wheel of the car with a metal bicycle handlebar. The drive wheel is driven through a chain drive from a screwdriver.

Assembling such a miracle technology will not take much time, and most importantly, money. All costs will be paid off with the joy of the child, for whom an electric vehicle will be a real gift.

Manual generator

A hand generator is a device similar to a wind generator. The manufacturing procedure is identical to the assembly of the wind turbine. At the last stage of work, instead of a nozzle with blades, a handle is attached to the screwdriver.

Drilling machine

Such a machine will turn out if you fix the 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.

Grinding machine

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