Battery life hacks and crafts

Sometimes batteries are used for other purposes than intended. This leads to battery life hacks. So, what can you make with used batteries at home? We'll tell you all about it right now!

How to make a stun gun from a battery?

To make it you will need:

1. Battery crownat 9 volts.
2. A conversion transformer. This can be removed from the charger or power adapter.
3. Ebonite rod 30-40 centimeters long.
4. Insulating tape
5. Wire.

Assembly process

To assemble a stun gun from a battery, attach two pieces of wire to the end of the rod. The wire should be 5 cm long and steel. They also need to be connected to the power transformer and the power source.

Next, you'll need to attach the battery to the two-pin connector on the transformer. A switch is attached to the other end of the rod. When pressed, an electric arc will flow between the steel contacts. For the human eye to detect this arc, you'd have to press the button a full 25 times per second.

The current in this homemade device is low, so it won't knock anyone out. Therefore, it can only be used for intimidation and defense.

How to make a bomb from a battery?

To make something popping from a dead energy source, you'll need to empty the zinc cup completely. Then, add gunpowder or something flammable. Finally, attach a fuse and light it. This article won't cover how to make battery bombs, as that information could be harmful not only to you but also to others.

How to make a magnet from a battery

To create an electromagnet from a cylindrical current source you will need:

• Nail.
• Thin copper wire, preferably varnished, so that nothing short-circuits.
• New current source.

Wind the wire around the nail, one turn at a time. The more turns you make, the less the current source will heat up. Then, attach a battery to the two protruding ends. Next, apply your electromagnet to the metal. For example, you can try magnetizing a nut or bolt.

How to make a hiding place from a battery?

Sometimes you need to hide something small, and a battery-based hiding place is quite suitable for these needs.

To make it, it is enough to take a power element, crown or type AARemove the contents and store the desired item. In the case of a nine-volt power source, you can remove part of it or even insert smaller power sources. This will result in it outputting nine volts, but it will also serve as a hiding place!

How to make a burner from a battery?

It is created using the short-circuit effect.

Tools required for the manufacturing process:

• Pencil.
• Battery crownat 9 volts.
• Insulating tape.
• Power supply connector.
• Two syringes.
• Pliers.

We'll need the needles from the syringes, so we'll take them right away. We need to remove the plastic part from the needles. We'll attach the needle to the pencil with electrical tape. Then we'll need to bend the needle slightly. We'll attach one of the wires coming from the connector to the attached needle.

Attach the second needle to the opposite side. Their tips should touch. Next, attach the remaining wire and secure everything with electrical tape. Now connect the battery and begin burning.

How to make a fuse from a battery?

The first thing you will need to do is select the tools below:

1. Matches.
2. Copper wire.
3. Battery.
4. Nichrome thread.
5. Electrical tape.
6. Scissors.

We strip the wires on both ends. Next, we make bridges on the wires using nichrome thread. After that, we take a match and make a small indentation in the center of its head using scissors. We fix the nichrome thread in this indentation. This fuse can be made without this thread.

How to make a lighter from a battery?

To create an electric lighter, you need to acquire the following equipment:

1. A 9-volt battery. It costs about 100-200 rubles. But you can find cheaper ones.
2. Thin wire, but it is better to use nichrome wire.
3. Wires.
4. Button.
5. 2 bolts.
6. Transparent glue.
7. Soldering iron.
8. Tin.
9. Rosin or soldering acid.

Apply glue to one narrow side of the power source and attach a bolt. It should have nuts. Repeat the process on the other side. Next, take the old dead battery and remove the terminal plate. This is the contact area. A similar connector can be purchased inexpensively at a radio supply store.

After this, we connect one wire from the connector to the bolts using a soldering iron. Next, we wrap the wire around a nail and make a spring out of it. We attach it to the bolts using the nuts we installed earlier.

We attach the second wire to the button and the battery. For more details on how to make a lighter from a battery, watch the video below. You could also use foil instead of wire. That is, you could make a thin strip and twist it into a coil.

How to make a tester from a battery?

Essentially, this is the simplest device. To make it, you'll need:

• Lamp.
• Button.
• Battery crownat 9 volts.
• Wires.

This test will easily determine whether the wire is intact or not. It's a good idea to find the dead battery and remove the contacts. However, if necessary, you can purchase a connector online or at a local radio store.

Now let's assemble a simple circuit! We connect one end of our light bulb to the connector. We attach a wire to the other end of the bulb. Next, we attach the tester to the battery using the contacts. The tester is ready!

In principle, it can be made from a phone battery. For more details, watch the video below!

Stylus from a battery

This device allows you to control your phone with your fingers. To use it, you'll need:

1. A current source, preferably a button-type element.
2. Nail 15 cm.
3. Sandpaper.
4. Cellophane bag.
5. Metal file.
6. Gel pen.

Trim the ends of the nail. If you have an electronic sharpener, this is easy to do. After that, grind the nail. Next, take a gel pen. Remove the cap. Glue it to the nail. Some pens have cylindrical rubber bands. This is the one we'll need. Glue it to the nail. Now attach the battery to the stylus, stretch the bag over it, and secure it with a rubber band. You can trim off any excess.

How to make a motor from a battery?

To do this you will need copper wire, a power source, and 3 button-type magnets.

You'll need to make a special rectangular frame. The video below shows how to make it.

So, you can easily make a motor from a battery and a magnet yourself. As you can see, it's not that difficult! Some similar models can also use paper clips.
