Not all old tablets support the function of connecting a flash drive or modem, but I will tell you how to outsmart them and connect a flash drive, modem, or even a hard drive to them.

Today I would like to present to your attention an OTG adapter.

First, I want to tell you what OTG is? This is a way to connect to your tablet or phone that supports the OTG function, printer, flash drive and even hard drive. This connection is also called USB-host.

You can also connect a keyboard or mouse to your gadget, if the gadget supports such a function.

And so, to create this miracle cable, we need:
Old USB extension cable
Micro USB connector (you can get it from a regular USB cable for your device)
Soldering iron and soldering accessories

And so, let's go, to make such a cable, we will need to connect the 4th pin to the 5th pin of the micro USB connector

We must get to the fourth pin and connect it with a jumper to the GND wire as shown in the picture

After we connect the 4th and 5th contacts with a jumper, our gadget will perform the function of an active device and will understand that another passive device is about to be connected to it. Until we install a jumper, the gadget will continue to fulfill its role passive device and will not see your flash drives.

But that’s not all; to connect a hard drive to a phone or tablet, this adapter will not be enough for us. To connect devices whose consumption is more than 100mA, namely 100mA can be supplied by the port of your device, we will need to connect additional power to our OTG cable, which should be enough for your hard drive to work.

Here is a diagram of such an adapter

Now it's time to start collecting
We take an old USB extension cable and cut it not too far from the 2.0 connector, since the current is only 100mA, to avoid large losses. Cut approximately in the same place as shown in the photo

Afterwards we clean our wire

I connected pins 4 and 5 with a drop of solder.

Well, here is our entire cable assembled

All that remains is to check the functionality, take the tablet, insert the “adapter” and insert the flash drive into it, everything works, as the flashing LED on the flash drive and the tablet detecting the flash drive tell us.

We welcome all beginners as well as experienced life hackers on this site!
We have an electronic magazine in which we write different interesting articles about useful gadgets and unusual concepts. We also look into the future or make the present more interesting, beautiful and useful. Read the next article of the electronic magazine.

Almost everyone has USB flash drives today. But despite all the diversity, the range of housings for such devices is quite limited. Why not make a case for the flash drive yourself? It's not as difficult as it seems, you just need to spend a little time. But you will become the owner of a unique thing.

So let's get started! Following step by step instructions, we will make a case for our USB flash drive from bricks from children's construction set Lego.

This is what she will look like

Tools and materials
Penknife
Pliers
Several Lego bricks
Super glue
Sandpaper
Metal polish
Flash drive

Step 1: Body Base

Internal elements are broken

USB memory cards are available different sizes. We will be packaging a fairly large board. Therefore, we will need a Lego brick of 6×3 cylindrical seating elements (let’s agree to call them “dots”).

You need to cut everything with a penknife internal partitions bricks and then break them out using pliers.

We use two more low-profile bricks with dimensions of 4×2 and 2×2 “points” to create the lid. Also for the lid you will need a low-profile element 1x6 “dots” (for the lid you can use other combinations of construction parts, or you can simply take exactly the same brick as for the base of the body (6x3) and carefully cut off its upper part with a jigsaw parallel to the horizontal plane).

Using superglue, glue the lid elements together to create a part measuring 6x3 “dots”.

Step 2. Install the board

Board in case

At the end of the case we cut out a groove for the USB connector, and after a little adjustment using a penknife we install the device into the case.

Step 3. Mounting the board

Fill the body with silicone

We place brick scraps on the bottom of the case and ensure that the board is parallel to the horizontal plane and does not press through. We fill all the remaining space in the case with transparent silicone, sealing it to reduce the possibility of any movement of the flash card inside the case.

It is important to use transparent silicone, since the indicator LED will need to shine through it.

Step 4. Gluing and polishing

Cleaning the edges

Polishes of different abrasiveness

To ensure that there are no gaps between the lid and the body, take sandpaper, place it on a flat surface, and level the bottom plane of the lid on it.

After we glued the lid to the body with superglue, using the same sandpaper remove burrs and glue smudges from the side edges of the case.
Then we finally polish the body with polish.

Step 5. Completion

The case is ready

Compare your exclusive and mass consumer goods

Looks stylish!

But that's it creative possibilities for creating exclusive flash drives is not exhausted. On the contrary, there can be an infinite number of types of cases for them.
Look what other craftsmen have done.

Do you have an original flash drive? What ways of individualizing this mini-media do you know?

Meanwhile, the mini-magazine still contains some unread curiosities: a visionary video about the medicine of the future; gadgets - a landline cell phone and a bottle for tourists to disinfect water. and don't miss anything!

Which is made by hand. You can make it for a loved one.
I suggest knitting as a gift original case for electronic media. In addition to pleasant impressions, a person will receive useful thing to prevent damage to the flash drive when dropped or exposed to low temperatures.
To work you will need: a flash drive, a ruler, a hook and thread.

The proposed model uses “Iris” cotton threads, but if desired and possible, you can use any.
Before knitting, you should measure the length and width of the flash drive. Knit a chain of 25 chain stitches, one and a half times longer than the length of the flash drive itself.

Then, without turning the product, we continue to knit stitches in a circle, sticking the hook into the air loops of the chain.

In the last loop we knit 3 single crochets. We proceed to the second row without a lifting air loop. Now we knit single crochets all the time in a circle without adding 11-12 rows so that the flash drive placed inside is completely hidden inside.

This produces a small bag with a height of about 2.5 centimeters.

We do not tie the connecting row to the end by 2 cm - a distance equal to the width of the flash drive, so that it can freely enter and exit the case. We pass the thread through the last loop and tighten. We pull the thread inside out with a crochet hook, fasten it and cut off the end.

For reliability, I recommend attaching the flash drive to the case. This way you don’t have to worry about losing the case and can comfortably wear it on your hand or neck.
You need to tie a string. To make it stronger, you need to knit it in two threads. To do this, you should unwind, without tearing it from the ball, a thread four times longer than the required lace. Then knit a chain of air loops of the required length with a double-folded thread.

When the lace is ready, we thread it through a special hole on the flash drive.

Turn the cover inside out and thread the lace through the bottom of the cover using a hook.

If your flash drive casing is worn out or the cap is lost, you can update it using an easy-to-use case "Owl". You can also bind a new flash drive as the original one. Master Class .

Knitted cover for flash drive "Owl"

To work you will need:

Iris threads, Fuchsia color, Lilac color, yellow, white and black;
hook No. 1.5;
loop with carabiner, for keychain, ready-made;
heat gun with rods.

Description:

Head + body with threads in the color “Lilac”

1st row - cast on 5 chain stitches + 1 chain stitch, then in the first loop, knit two half double crochets, from the second to fifth loops, knit one half double crochet into the corresponding base loop, into the fifth loop, tie three half double crochets. Next we knit on the cast-on chain on the other side, making an oval. Until the end of the row, knit with half double crochets in each loop, including the tenth (aka the first).

2nd row - do not make lifting loops - knit spirally with half double crochets, this will look neater.

After knitting two or three rows, be sure to try it on your flash drive; the knitting should not fall off it.

So knit to the length you need, in in this example this is 13 rows. Finish knitting like this: when you reach the “sidewall” of the flash drive, knit four single crochets and three half-crochet stitches into the corresponding loops of the base, as if smoothing out the spiral.

Knit the head in a similar way, only reducing the number of rows to six, and in last row Using single crochet stitches, connect the “head” to the “body”. Before you cut the thread, be sure to check that the head can be removed well.

Wings with fuchsia threads:

1st row - cast on a chain of 5 air loops (hereinafter VP) + 2 lifting loops;

2nd row - in the first loop, knit two double crochets, from the second loop to the fourth, knit one double crochet, in the corresponding loop of the base, in the fifth loop, knit seven double crochets. Continue knitting in the same row, making an oval. And so on from the sixth to the eighth loops - knit one double crochet. In the last loop, in which two stitches are already connected, add 4 more double crochets, secure the row with a connecting loop;

3rd row - three air loops, single crochet in each corresponding base loop around the entire circle;

4th row - one single crochet, three chain stitches and secure them with a single crochet under the arch of three chain stitches of the previous row, so knit to the end.

Eyes:

Turn on the hot glue gun to warm up, and in the meantime, thread white cast on a chain of six air loops, close it in a ring, hide the “tails” and cut the thread. Using black thread, make a chain of three air loops, also close it into a ring, but leave long ends. Insert the black part into the white “donut” and, holding everything by the long ends, coat everything with hot hot glue. Now you can trim the long ends of the black threads.

Make two eyes this way.

Beak yellow threads:

Cast on a chain of three chain stitches, two instep stitches and knit unfinished double crochets from all stitches, finishing them with one loop.

Tassels Fuchsia threads:

Take the connected body and head, cut about 10 cm of fuchsia thread, fold it in half and pull it through the loops of the head with a crochet hook, secure with a knot and trim evenly. Make two tassels.

Now it's time to attach all the parts. You can sew them on, but a heat gun can handle this faster and easier. First glue the beak, then “crawling” onto it a little, glue the eyes.

Now turn the owl back and apply glue to the center of the wings and glue them to the body.

Turn the owl “face”, add wings to the front, hook it with a keychain holder and that’s it.

The owl flash drive is ready!

Now the flash drive has taken on a completely different look. In addition, according to Feng Shui, it is a symbol of wisdom and knowledge, helps to succeed in studies, and helps those who do not study to manage their lives wisely. So now you also have a good talisman.
