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:

Picture of
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.

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

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.

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)  Glo0my1 year ago
I am glad to hear that! I hope you enjoy wearing it.

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)  Glo0my1 year ago
Thanks! I don't see why it shouldn't work. Your bracelet will just get thicker.
can you use a different usb, 'cause that's a bit too expensive for my budget

Even the 4 GB one?

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

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)  nhormell2 years ago
Oh no, please tell me you are joking, if not I wish you all the best and hope you recover fast.
no joke but the eye is one of the fastest healing body parts recovering very fast
i guess we need to wear eye protection now when using super glue. hope the eye is better.

this is great wish I had thought of it. did you use corrugated cardboard? where did you get it?
BrittLiv (author)  chemkid422 years ago
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.
chemkid422 years ago
still a little confused on how you did the cap?
BrittLiv (author)  chemkid422 years ago
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.

Is the usb drive still waterproof if you remove the case?
BrittLiv (author)  gilgolf2 years ago
Hi, yes it is, if you take a look at the first picture of step 3 you can see the back of it.

Such a cool idea...but....aren't you using embroidery thread and not yarn?
BrittLiv (author)  microfarm2 years ago
Thanks a lot, I thought that embroidery thread is yarn, but you are right it is the better description.

Could explain in more detail how to make the cap hold on to the usb stick in a firm way?
BrittLiv (author)  korlik2 years ago
Sure, the fit is very tight and the duct tape on the inside prevents is from sliding out.
