Make an awesome case-less flash drive, Did I mention that it's water proof?

Step 1: Gather materials

Picture of Gather materials
You will first gather your materials that you will need to make the flash drive,

You will need tape,



Two cups,

A small DISPOSABLE paint brush,

A plate,

And a tooth pick.

A dremel can also come in handy.

Step 3: Thread the string through the cups

Now thread the string through the holes in the cups and tape the string down as shown...

Notice the plate? You will be needing a few so now would be a great time to go get them,

I'l wait...

Step 4: Time to open the flash drive up...

It is time to CAREFULLY pry opened your flash drive,

Take care not to break circuit board inside....

Step 5: Put some wire through usb connecter on flash drive (To hang it up)

Now you will need to put some wire onto the flash drive so that it can hang up to dry later...

If your flash drive does not have holes, Then you can skip this step.

Step 6: Time to mix the Epoxy

Now mix your epoxy on a plate (disposable plate !!!!), most epoxies use a 1:1 ratio of resin and setter (For a lack of a better word).

Remember to always use gloves and safety glasses while using any chemicals (Epoxy included).

Step 7: Brush epoxy CAREFULLY onto flash drive

Now use your brush to brush the epoxy onto the flash drive,

Be very careful not to get epoxy on the USB connecter...

Step 8: Hang it to dry

Now it is finally time to hang your flash drive up to dry,

hang it up using a clip...

If your flash drive doesn't have holes just clip it up using the usb connector...

Step 10: Take off the annoying drop of Epoxy...

Now take a file or some diagonal cutters and just take off any excess resin...

Let me ask a question. Why are we using a flash drive underwater?
ilikecake31 year ago
I thought if the USB thingy that went into the computer got wet it would break

very nice, it think clear caulking will work too. no need for it to be water proof.

I think it is a cool. At my local BestBuy they have this super water proof drive that i think is also the same idea but this seems cheaper! The one I saw was $60.00 for 4GB
for me, a 2GB waterproof flash drive cost about $12 ( $11 for the flash drive and $1 for the superglue.)
but superglue will wash off in water
Why do you think so?
well I know because I have put superglue on other things that will go into water, the glue will eventualy wear off. And the super glue that i use says on the back of the package that it is not recommended for use in wet locations, but your superglue may be diff. I know that you can buy waterproof superglue from automotive stores but its almost twice as much as regular super glue in my town anyways

 painting it in epoxy will slowly kill your usb over time, the chemicals will dissolve the solder connections and make it unusable and unfixable.

No it won't.
I have drives that have been epoxied since 2003 that still work normal.
EPOXY is harmless to a flash drive.
will it really?! how do you know this? because i really want to do this to my flash drives. but i dont want to mess them up. can you supply a source?
it happened to me! instead of epoxy why don't you try some silicone sealant or something else clear
really?! that sucks! i mean how could you tell i mean could you see that it dissolved the soldered connection? and i should use the normal everyday silicone in the tube? have you tried this? ill probably go with the silicone. also. what about acrylic? im sure they make acrylic resin that will harden when dry

You said you couldnt find a word, so heres a free one.
Instead of setter, catalyst. Hope it helps!

Its better if you place the entire thing back in the case it came in, essentially expoxy it into its case, its a far stronger solid unit. I suggest epoxy putty would also be an option, you can mold it into any shape as well for a bonus, but an underlyinglayer of liquid epoxy is probably a good idea for water seal.

Why wouldnt it still work if you just left it in water without epoxy?
Look away! It's bold! lol, nice one!

question... can the drive work while submerged???
I don't know, but I would think so if the red indicator light is on in this picture.
One. wizard7225 years ago
 the light will only show if the usb has just been plugged in, or you are transferring data. (+[__]::)

if it is tranferring means its working...
It does! (if you make it properly.) i"ve tested mine and it works!

Did you also water-proof the connector, and extension somehow? Because unless you are using VERY clean (as in distilled) water then that should be shorting...
no! if you water-proof it, it wouldn't connect with teh computer because the contacts will be sealed. The interference and resistance of water is too small for the signal to be disrupted (unless the water is VERY salty). I would not suggest to keep it in the water for a long time, though.
rofl thats not what I meant, you CAN get water proof connectors you know lol I meant something like soldering the 4 contacts onto some kind of waterproof connector with 4 pins (or whatever said connector uses) and then water proofing the soldered joints, and doing the same to an extension cord... Well something along the lines of that you see what i mean now? I know that if you seal the connectors it wont work lol It would be a pretty bad sealing job if it did
It will work well without the waterproof connector. The main reason why you would want to waterproof the flashdrive is that the circuits in the circuit boards corrode under water and get trashed. The USB connector is too big to be trashed by corrosion.
We are talking about actually using it under water aren't we? Flash drives are pretty delicate pieces of electronics, and while they can be dipped in water many times and last for years - corrosion isn't really a problem unless you are using salty water, using them under water howeveris a different story. You definitely need to waterproof the circuitry of the flash drive, and I know its only 5v but you should still use special waterproof connectors when using this thing completely submerged under water.
the corrosion is faster if there is some voltage on the contacts that are submerged in water. And as the micro-curcuits are extremely thin, they will degrade to zero in no time. But teh connectors are thick enough to resist corrosion for some amount of time.
In Popular Science I read about this knew process that will bond a water-proof mixture to surfaces but it is thin enough that even if you coat an entire flash drive it will still work. Here is a link to the company.

That is the single worst piece of physics I have ever read.
haha good one
Uh... NO. You might want to look these things up before you make yourself look stupid :P Water itself does not conduct electricity, its all the impurities and salts dissolved into it that make it conduct electricity.
Yeah, that's right. Chemistry class For The Win!
omg is that file "im still alive" the song from portal? or is it theparamore one. wait or is it evanecense? anyway yeah
i think its just to say the flash drive is "still alive"  although the thought about the portal credits song went through my head also :)
Or just a word document :P
ha ha ha... which document reader are you using? mine is struggling to read, never mind singing...? :P

what usb is that? i have one just like that from computer active

great ible

keep it up
