Step 1: Materials and Tools

Picture of Materials and Tools
  • Two small shotgun shells
  • One USB
  • Foam/Tissue/Sponge
  • Paper
  • Red pen
  • Electrical Tape

  • Vice/Clamp
  • Craft Knife
  • File or Dremel

Step 2: Stripping the USB

Picture of Stripping the USB
We need our USB to be as small as possible so it can fit in the two small shotgun shells, this means we need to remove the outer casing.

Using your craft knife pry at the edges of the case forcing it apart.
(The cases are generally pretty to take off)

You can now throw away any of the plastic casing
(Better yet recycle it !)

Step 3: Preparing the usb

Now you have removed the protective casing it would be a good idea to cover up the bare circuit board with a bit of electrical tape.

The tape will protect the circuit from short circuiting or getting damp.
(Still best not to go swimming with your USB :P )

Step 4: Filing the Shells

Picture of Filing the Shells
Because of the small "lip" at tho bottom of the shell the two cases wont stand very close together.

To make them stand snug together we have to loose a bin of that "lip"

Clamp the shell in your vice/clamp and then use your dremel or hand file to flatten one side.
Repeat this process for both shells and check they fit together.

Step 5: Cutting the slots

Now we need to cut the slots in the sides of the shells so our USB can fit in.

First mark the shell with a pen to show how much to cut, this will prevent you from cutting too much and loosing the aesthetics of the shell.

Now you have marked the shell carefully cut a slot into the side with your craft knife, do this to both the shells.

Step 6: Assembling the case

Now we have the slots cut into our shells we can finish up the project

First put the USB into the slots, then for extra protection get some sponge/foam and your craft knife
Cut strips off and stuff them into the space surrounding the usb.

Once all the space is filled get some paper and cut two small disks, then trim them and glue to the tops of the shells. Once glued use a pen to colour them in so they blend in with the rest of the shell.

If you get lost then just look at the pictures or leave a message !

Step 7: Finished !

I'm assuming those are 20 gauge shells right? I think it would be even better if you could fit a USB into a single 12 gauge shell.
i think this is what u mean: http://www.instructables.com/id/Shotgun-Shell-USB-2/
I think they may be .410 bore shotshells... they look pretty small
they are 12 guage shells standard red color and pretty ordinary.... just like the ones i use
Those are .410 shells, they are .410" in diameter, a 12 ga. shotgun shell is .75" in diameter. You can see these are .410 shells when you compare the male USB 2.0 connection to the diameter of the plastic shell, male USB 2.0 connectors are .5" in width. You state that "they are 12 guage shells standard red color and pretty ordinary.... just like the ones i use", the color does NOT indicate the size of the shell ( this picture shows just that http://tinyurl.com/244v69p ) and if you truly do use a firearm of any kind, I suggest you go to a hunter's education course.
Wow. Someone did their homework :D
Homework, and a passion for my 2nd Amendment rights. :)

nice idea i would recommend using a 20 gauge or a 12 gauge shell instead of a .410.
the red ones used here are standard 12 gauge, so yes i agree 20 gauge are slightly smaller so it really depends on the size of the flash drive
Judging from the size of the USB plug end, these are NOT 12 Gauge shells, definitely .410 shells. If 12 Gauge shells were used in this project, only ONE shell would be needed because a 12 Gauge shell is plenty large enough to hold a USB flash drive.

Great instructable!

When your USB is plugged in, it looks like your computer has been shot by two bullets!
hey plasmana, i guess you have never been around guns or even shot a gun or you are just a little kid, because the shell (or casing in a rifle) does not leave the gun.. only the bullet or pellets or BBs do.
WRONG! The shell does leave the gun.
A mere technicality on my part, yes the shell does leave the gun *when ejected after being shot* but what I was trying to say is that the shell does not go flying out the barrel when it is shot. That is what I meant by "does not leave the gun, just the bullet, pellet, etc.."
I know, i was just being tight.

MISUNDERSTAND! The shell doesn't come out the end of the barrel, it is ejected out of the chamber to the side
Yeah, thanks for pointing that out, I know the case does not got with the bullets, lol. I'm just saying it "looks" like the computer has be shot. :-)
so really, the computer does not look like it has been shot...just saying

Good Ible. Use already discharged shells Right? I assume so, but didn't see a warning, and there are some people out there with the lack of brains to try using live shells.

hahaha yea their used, ill post a warning

Thanks :D , What phrase ? lol
"Good picture if I may say so."

By making the land at the bottom larger you could solder the bases of the shells together (not to be tried with un-discharged shell I hasten to add) and reduce the distance between the two bodies almost to nothing. Nice USB mod though. I'm just waiting for the first gringo to make a bandolier of these bad boys:)
