Detailed instructions on how to make your own flashlight, please.

The first step is to prepare all the materials: a metal box with a plastic lid (like eight treasure porridge), 2 AA batteries, a 2.5 V light bulb, 15 cm of thin wire (you can use the wire from a waste feeder), soft filling (bubble wrap, cardboard, rags, etc.).

The second step is to use a hammer to pry the center of the bottom of the tank several times to make better contact between the bottom of the tank and the negative electrode of the battery.

In the third step you can already see that the bottom of the box is recessed. Cans like this have film inside. This affects the conductivity. You must use a hard object, such as a hard object. a screwdriver, to severely scratch the box. Only by destroying this film can we conduct electricity efficiently.

The fourth step is to make a hole in the middle of the plastic cover.The goal is to attach the bulb to it. The holes should be made slowly from small to large, while comparing the size of it. the bulb with the bulb size. Do not make the holes too big, otherwise the bulb will not be stable. Before installing the bulb, remove the wire jackets from both ends of the thin wire. Wrap one end of the wire tightly around the bulb and pass one end through the side of the plastic cover. This section will become the flashlight switch. .

The fifth step is to connect the two batteries, paying attention to the positive and negative poles. Needless to say, you should use tape to secure them, and the connection should not be loose. Then wrap the exterior with soft stuffing, secure it with tape and place it in the pot. Finally, use padding to plug it in tightly so that the battery is in the center of the pot. Never let the batteries rest in the jar. The jar is loose.

The sixth step is to close the cover so that the lower end of the bulb is in contact with the positive terminal of the battery. The exposed end of the wire is the switch when the wire touches the wall. from the tube, the bulb will light up.

Note: If there is paint on the outside of the can, it is not conductive, so the wire should touch the exposed part of the metal skin. You need to know where to touch.

The flashlight The waterproof level is generally level 8. Now most of them are waterproof level 7, and some are waterproof level 8. At present, Micros waterproof film is used in China for protection, which meets the level 7 flashlight waterproof requirements, which means it will not be affected by 1 meter of water during 30 minutes. Micros waterproof membrane can meet the requirements ofwaterproofness of level 7 and also has the following characteristics:

1. Waterproof, dustproof, oilproof and the protection level reaches IP68.

2. Prevents condensation and fogging and extends product life.

3. Heat dissipation and balanced pressure difference. Improve product integrity.

4. Resistant to chemical agents, high and low temperatures, anti-aging, etc., to improve product reliability in harsh environments.

The waterproofing of outdoor flashlights is receiving more and more attention to improve the quality of outdoor activities. Micros waterproof membrane, a new solution for waterproofing outdoor flashlights!
