How can I make a USB flashlight at home. USB flashlight: existing types and tips how to make a lamp with your own hands powerful pocket flashlight

Many of us love to play on the computer at night. Many prefer to work at night, because they love when they do anything around them. In such cases, a night light is needed, and better if the portable flashlight is available, which can be connected to a computer or laptop and illuminate the keyboard, as well as the workspace. This material will describe the process of creating a homemade lamp for a computer, which can be connected to a USB computer connector.

See how to make a USB flashlight:

So, we will need a wire, USB plug, LED, as well as the basis on which it will all be installed: As the basis, you can use an old lighter from the gas stove with a corrugated part. If there is no such lighter at hand, you can separately remove the corrugated part from computer headphones with a built-in microphone. As for the LED, it can be spilled with an old computer mouse, and the USB plug can be removed from the old flash drive or MP3 player.

First of all, we need to reconstruct the LED light bulb from the mouse.

Next, you need to reconstruct the USB plug from the player or drive.

After the USB plug and the LED light bulb, they need to be combined with each other and install the lighters in the case. The LED has a plus and minus, that is, anode and cathode. The question arises: how to distinguish them? The contact of the smaller LED is the plus, and the contact that is more is minus. Now you need to define the plus and minus contact on the plug. In the position of the plug, when the plate is at the bottom, the right extreme contact is a plus, and the leftmost is minus.

The minus and the advantages are found, which means that you can proceed to their connection using the wire, as well as the installation in the housing of the lighter. First of all, you need to solder wires to the plug.

We disassemble the lighter, removes all the inner of it, because we all do not need it. Next case cut off the bottom, leaving the place for uSB installations plug.

Wires need to be covered through the corrugated part, install the plug into the housing of the lighter and fix all the thermoclaim. When the wires are sucked through the corrugated part, they can be soldered to the LED light bulb. Light bulb should also be fixed with glue, and after - collect the case and connect to the computer.

Many lovers computer games Prefer to spend at night. Those who earn on the Internet often often make it at night when there is silence, no distracting interference. And those, and others need a night light or some illumination, which allows you to see the keyboard well and does not interfere with other bright light.

A good solution solution will be a simple flashlight that connects to the USB port of the computer, a laptop. How to make it yourself - further in the article.

For a flashlight, first of all, you need to find the basis. It may be, for example, a lighter, which was buried before the slab, and now it dust in the closet. A corrugated part is suitable from headphones connected to a computer.

For the flashlight needed too:

LED, similar to those supplied pC mouse; From it it can be dropped;
USB plug, which is on any old flash carrier, in the MRZ player;
Flexible wire.

First remove from mouse, drive or player, using a soldering iron, respectively, a LED light bulb and a USB plug. Then they are connected between themselves consistently and insert the housing of the lighter. The LED has two contacts - plus and minus. The latter is always greater than the size. At the plug, if it is planed down, the minus contact is right.

The plug connection with the light bulb is carried out with wire. They are sold first to plug contacts. Then disassemble a lighter: all internal parts are removed from it; Cut down the lower part, leaving the top length under the size of the plug.

Wires that previously soldered to the plug are focused through a corrugated plot. The plug is started in the housing inside and fix it there with thermoclaim.
The next operation is a shut-off of wires, with respect to the polarity, to the contacts lED light bulb. It is also fixed with a thermal oil, after which the case is collected.

USB flashlight ready. The plug is introduced into the corresponding computer socket, after which the light begins to burn. It is fixed in the right place and are given to your favorite work or games.

The length of the wires connecting the light bulb with the plug in advance are calculated. It should be sufficient so that the lighting can be brought to all necessary when working places.

As a lantern option, two light bulbs are connected to the plug, which are located in parallel or sequentially. This flashlight can be provided with lighting more extensive areas, which is especially convenient when working on the Internet.

Today you can find many different small gadgets for your phone and computer. Something you can buy, and something to do something yourself. The following examples will be for lovers of self-smoking by another pleasant find.

Assembly

Consider the manufacture of LED USB flashlight. Although this thing is possible for a penny to buy in the store, in this case the manufacturing process itself is pleasant. It will be a good addition to the phone where there may be a lantern.

On the example, consider how to make a USB flashlight with your own hands. Prepare a few girlfriend, and tools:

A small LED. It can be bought as a separate element or drop out of unnecessary deviceFor example, from residues LED tapes. In this case, you can take a couple of light elements immediately;
USB plug. It can be cut off from an unnecessary charging cord;
soldering iron;
flues;
solder.

Making a USB flashlight at home is a fairly simple process. With cut uSB plug It is necessary to remove the plastic case. It is cut on both sides, trying not to disfigure appearance. In the future, it will be used again as a housing. From one side, small squares cut through the center, which will serve as windows for diodes.

The remaining wiring is disappeared from the metal plug. It is necessary to remember the color location of each of them (plus and minus), it will be easier to connect power for diodes.

Available LEDs should be checked for performance. They are connected to 5V battery. If they are workers, then inserted into the removed plastic cover, and on the reverse side of each element, they are lubricated by the superclay. The casing with the elements is dressed on the plug, and presses for the speedy fixation of the glue.

The elements were glued! Again you need to remove the casing. Two diodes sold out with small wires parallel to each other. This is done through the resistor (from lED tapes) to the main power supply of the plug

The main work on the assembly is over, the flashlight connects to the phone to check the brightness. It depends on the number of connected resistors, in this example Their 3pcs.

The casing is put on the plug, and its interior is filled with glue. The finished device must be pressed to harde the glue. Such a device simple USB Lantern.

Powerful pocket flashlight

You can implement the device more difficult. He can come to replace any Chinese flashlight having charger. Consider the manufacture of LED flashlight with USB charging.

The product will include the following items:

powerful good quality LED;
focus lens;
driver limiting current flow;
controller with indicator. It is used in automatic charging of the battery;
protective circuit from the discharge of AKB;
large capacity battery;
clock Button for On / Off Lantern.

On the scheme of the homemade LED USB flashlight can notice the absence of microcontrollers. Its simplicity allows without pre-tuning Immediately turn on the flashlight to work.

In this case, it is more difficult to choose a good body. On the example, we use the plastic plumbing clutch. The plugs are removed from both sides, and holes are cut on each of them.

Under the LED, the hole should turn out round, and for the charging socket is square. Also do not forget to make small holes for the indicator and buttons. The circuit board in the plastic coupling sits tightly, so it is not necessary to make an additional seal for it.

IMPORTANT! For the light element you need to install the radiator, otherwise overheating is possible. In this example, the LED consumes 350mA.

After the assembly, we see that on one side of the case, the power button, indicator, and the charging socket are located. There is only a LED in front. Inside, the light element and battery are divided by the board.

At the final stage of assembly, mounted optics on the light element. We dress the plugs, and get a finished lantern of manual assembly. During battery charging, the indicator displays an orange glow. When the battery is fully charged, the indicator will glow green.
