Introduction: USB Flash Drive Bracelet

Picture of USB Flash Drive Bracelet

In this instructable I'm going to show you, how to make your own USB flash drive bracelet. I've seen quite a few before, but never really liked the designs. My goal was to hide the flash drive entirely in the bracelet. I decided to make one with yarn and after a short search I found this amazing blog post, that already showed what I had in mind.

Step 1: What You Need

Picture of What You Need


• Embroidery thread (I used about 12m)
• Flexible cardboard
• Duct tape
• Tape
• Super glue
• Verbatim TUFF 'N' TINY USB Flash Drive (e.g. on


• Scissors
• Ruler

Step 2:

Cut the cardboard to a width of 3.2 cm and a length that matches your wrist. Remember to make it slightly longer, because the yarn and duct tape will make it tighter.
Then fold the cardboard length wise in half and tape it close with the duck tape, but remember to leave the ends open, as shown in the first image. Cut one end open, put duct tape on the inside and tape it back close. This side is going to be your cap so make sure that it fits without sliding out. Now peel the casing of the flash drive off. To smoothen the edges of it (else the end can be seen through the bracelet) fold a piece of cardboard and use the super glue to glue it to the flash drive. Leave enough space as shown in the third picture to make sure that you get a tight fit. Glue the flash drive to the inside of your tube and make sure that it closes, without leaving a gap.

Step 3:

Picture of

Start by dividing the length of your bracelet by the number of colours you would like to use and how often you would like to use each, to know how long each segment is going to be.
Use tape to secure the first yarn and apply super glue to the rim of your bracelet, to prevent it from sliding down. Wrap the yarn around your bracelet, as close as you can and once you are done tape the end to it as shown in the second image. To change the colour tape the new one slightly above the old one and wrap it around as close, as possible. Once you are done secure the end of the last colour by applying super glue underneath it.

Have fun with your new bracelet.

Really cool! You've got my vote

HLightning11 (author)2016-03-08

could you not use string, but colored duck tape instead, and use the lid of the usb as a closure? although, i only looked at the pictures

Technocat568 (author)2016-03-07

This is really cool! Instead of using string, you could use circut duct tape!

Hi, thats a cool band up there. this is my usb i dont know how to open it and i really want to make that band. I love it.

Hey there! I've had flash drives like yours, and it might not work the best for this design because it's longer internally. However, if you still want to open it up, there should be a couple grooves along the sides of the drive. You can wedge a knife in there and crack it open, but be warned, you probably will break the casing.

Here is my flash drive. How can I make one for this?

BrittLiv (author)HiPoweredHacker2014-10-21

Hi, I think making the bracelet the way I did with your USB drive is difficult. Maybe you can just make an entire bracelet with a small pouch in which the USB drive fits.

Ravirar (author)2014-03-13

there us a SanDisk USB that you can buy which the total length is about 2 cm, and can go up to 32gb, so its good for this bracelet. I had one of these, except it was a watch that could not only show time/date, but could show how much space is available on the drive built in bracelet style. Sadly it got wet and stopped working. :(

I've just finished mine and as you said IT WORKS !
I used a very old USB key so it's thicker and the width is 4.2 cm ( instead of 3.2 )

BrittLiv (author)Glo0my2013-08-18

I am glad to hear that! I hope you enjoy wearing it.

Glo0my (author)2013-08-14

Very cool project !
I have just one question : does anybody try this with a "normal" USB key , i mean a bigger usb port ?

BrittLiv (author)Glo0my2013-08-14

Thanks! I don't see why it shouldn't work. Your bracelet will just get thicker.

blackjackrobo (author)2013-08-08

can you use a different usb, 'cause that's a bit too expensive for my budget

BrittLiv (author)blackjackrobo2013-08-09

Even the 4 GB one?

Asriel Grim (author)2012-12-31

amazing 'ible as always and great taste in fashion! The color combination really rocks! Well done!

Bomshika (author)2012-05-21

I can't seem to download the PDF. Is there another way I can get it?

BrittLiv (author)Bomshika2012-05-22

As far as I know only pro members can download it. Send me a pm with your email address and I'll email it to you.

huynguyen207 (author)BrittLiv2012-09-08

bbaum1 (author)BrittLiv2012-08-23

clogie (author)2012-05-26

beadinggem (author)2012-05-17

Great tutorial! This sure makes "high tech" jewelry a lot more appealing! Will likely feature it on my blog in the future!

BrittLiv (author)beadinggem2012-05-25

Hi, I just saw, that you featured it, thanks a lot!

beadinggem (author)BrittLiv2012-05-25

My pleasure!! By the way, I too am a scientist but a lot closer to retirement than you are! ;-)

nice selection of thread colours by the way...

nhormell (author)2012-05-14

i love it
only one problem when i was making it super glue squirted up into my eye
went to the eye doctor and got the glue removed... chemically burned my eyeball
good project though

BrittLiv (author)nhormell2012-05-14

Oh no, please tell me you are joking, if not I wish you all the best and hope you recover fast.

nhormell (author)BrittLiv2012-05-15

no joke but the eye is one of the fastest healing body parts recovering very fast

i_am_joey (author)nhormell2012-05-22

i guess we need to wear eye protection now when using super glue. hope the eye is better.

chemkid42 (author)2012-05-19

this is great wish I had thought of it. did you use corrugated cardboard? where did you get it?

BrittLiv (author)chemkid422012-05-19

Thanks a lot, I used an old box you can see it in the first step underneath all the other stuff. For example a cereal box will work great.

chemkid42 (author)2012-05-19

still a little confused on how you did the cap?

BrittLiv (author)chemkid422012-05-19

The cardboard forms a tube, which can be used as a cap. To give it a tight fit I used duct tape that I stuck to the inside of it. The USB flash drive is glued to the other side.

gilgolf (author)2012-05-18

Is the usb drive still waterproof if you remove the case?

BrittLiv (author)gilgolf2012-05-19

Hi, yes it is, if you take a look at the first picture of step 3 you can see the back of it.

RightShoe (author)2012-05-17

hey, that is amazing. You should kick it on kickstarter and make some good money for very creative idea. I woild buy it for sure!

microfarm (author)2012-05-17

Such a cool idea...but....aren't you using embroidery thread and not yarn?

BrittLiv (author)microfarm2012-05-17

Thanks a lot, I thought that embroidery thread is yarn, but you are right it is the better description.

korlik (author)2012-05-17

Could explain in more detail how to make the cap hold on to the usb stick in a firm way?

BrittLiv (author)korlik2012-05-17

Sure, the fit is very tight and the duct tape on the inside prevents is from sliding out.

tqwerty (author)2012-05-14

This is so cool!
You've got my vote :D

peyton14 (author)2012-05-14

poofrabbit (author)2012-05-13

This is great! Are you going to enter it in the spy contest? I 100% think you should, well done!

BrittLiv (author)poofrabbit2012-05-14

Hi, thanks a lot, I have entered it (it is pending for approval).

poofrabbit (author)BrittLiv2012-05-14

Sweet! You have my vote :)
