What can be drawn from the batteries: a magnet, a stun gun, a lighter, AA from AAA

Life of modern man is hard to imagine without a variety of devices. For many of them require small batteries - batteries. But experience has shown that we do not know much about all of their options. For example, from conventional batteries can be made several original things, and when they're gone, dispose of them correctly.

What can be made of batteries

If you mobilize all their imagination, even of conventional devices will be able to make something unusual.

Magnet batteries

To make yourself a magnet, you will need:

1. Copper wire. It is advisable to take lacquered. So the device will not close during operation.
2. New battery.
3. Small stud.

Copper wire gently wrap on a nail. The coils must be located as close as possible to each other. The two free ends are connected to the battery.

Reference. The more you do the turns of the wire, the lower the heating device.

Taser

Prepare the following materials:

1. The battery type "Crown".
2. Transformer. It can "borrow" from the charger, a modem or other equipment having a power supply 9 V.
3. Ebony rod length of 40 cm.
4. The steel wire is 5 cm long.
5. Electrical tape.

assembly steps:

1. To one end of the rod ebonite attach two pieces of wire.
2. Connect the two pieces of wire converting transformer.
3. Connect the battery to the transformer terminal.
4. At the other end of the rod, place the switch. When you press the arc should appear on it.

Reference. It should be borne in mind that the current strength in a makeshift device will not be enough to "knock out" the person. Taser can only be used as a deterrent.

Miniature Heater Hand

As you know, there are two kinds of people. Someone freezes even in the middle of a hot July, and some are ready to flaunt with bare hands even lyutom frost. If you belong to the first group, you just need a mobile heater for the hands. Take two batteries and wrap them with foil, carefully pressed to positive contacts. Click on the "plus" and you immediately feel like your hands are warmed.

AA from AAA

You have purchased the wrong batteries? Nothing wrong. If you can make from AAA AA help small pieces of foil. Insert the batteries in the device and secure them with foil.

Lighter of batteries

To make lighter, prepare the following materials:

1. "Crown" at 9 and a new one issued from the system.
2. Thin wire. If possible, replace it with a Nichrome.
3. Cable.
4. Glue.
5. Soldering iron and all the necessary tools for soldering.
6. Two bolts and nuts.
7. Button.

Once all the materials are prepared, you can proceed to the assembly:

1. On one side of the battery apply a thin strip of transparent adhesive glue and one of the bolts.
2. Repeat the other side "crown".
3. Take unusable "crown", disassemble it and remove the plate with both positive contacts.
4. One of the contacts by means of a soldering iron to connect with bolt.
5. Take the nail and wrap the wire to it. It should get a spring.
6. Fix it on the bolts with nuts.
7. The second wire is connected to the first button, and then with a "crown".

Stylus

Minus side of any power element is a fine stylus for a touch screen

Fire from batteries

This is one of the most popular life hacking. To do this you will need a small piece of foil on a paper basis. For example, you can take a pack of chewing gum. Attach it to the terminals of the current source and bring to the subject that you want to burn.

motor

Take a thin copper wire, a current source 3 small round magnet, a pair of paper clips and reinforced tape. Next, proceed to the motor of the assembly:

1. Wire wound on a supply member. You should do at least seven turns.
2. Remove the resulting "spring-loaded". Bend the ends of the wire around it. Carefully treat their skin.
3. Straighten a paper clip. One clip with the help of an adhesive tape to secure the end of the battery. Repeat manipulation on the other hand, taking the second clip.
4. Bend them at the right angle and secure spring-loaded wire.
5. To bring the motor to move, put on the battery a small magnet.

What can be done from the old batteries

Do not rush and throw defective batteries - they can give a second life.

Even shrunken the battery can be made to work. To do this, gently deform her body. This should be done carefully so as not to disturb the tightness of the device.

You can also make an original lamp. You will need:

• old but not damaged the current source;
• miniature lamp;
• copper wire;
• stationery tape;
• paper, polymer clay.

manufacturing steps:

1. Divide the copper wire into two equal halves.
2. With the help of an adhesive tape, attach one part to the negative terminal.
3. The second half of the wire wrap socket on the bulb. Its free end of the lock on the positive contact of the battery.
4. To turn on a light bulb, close the circuit.

Correct disposal of batteries

It is not recommended to recycle have become unusable batteries as the rest of the garbage. The reason is that the apparatus includes a variety of substances that cause significant environmental damage, such as:

• electrolytes;
• acetylene black or graphite;
• the capsule is made of steel;
• plastic and paper components;
• manganese dioxide.

The housing unit over time begins to rust, and thus lose the original leak. Because of this, the toxic substances are released into the soil first, and then into the ground water. Next underground water streams carry them in large bodies of water.

Therefore, in all countries, it has developed a system of recycling of batteries. Decayed products are widely used in metallurgy, in the manufacture of fertilizers or pencils.

Some large supermarkets, for example, take the IKEA old sources of power. To do this, they placed special containers bright yellow. Also, the batteries can be handed over to the organized reception points.

If you want to make something original, or prolong the life of a battery, remember - your experiments must be safe. It is not necessary for it to draw young children and use damaged batteries.
