Back in March I posted about a Customized USB Drive that I thought was pretty cool. Someone took an el-cheapo USB drive and stuck it inside a Lego brick. In the same post I talked about a quick-and-dirty USB drive mod of my own, the Electrical Tape USB Drive. Basically, it was a clunker I picked up at CES that fell apart, so I removed what was left of the casing and wrapped it all up in electrical tape. Funny thing is, it's so fugly that when I recently forgot it in a school lab it was still there a few days later. Things might have been different had it been a SanDisk Cruzer or Corsair Voyager... or if it didn't have "62.4MB" written on it.

As simple as my electrical tape USB drive mod was, I had a good time making it and decided to come up with another, different USB drive mod. Luckily, I had another USB drive, which I'd also received from CES, but this one was a whopping 512MB - yeah, they make 'em that big these days... Unfortunately, as it were, this one wasn't quite so fragile, and I actually had to punish it thoroughly before I could get the casing off. But I'm getting ahead of myself...

In this article I will walk you through Project: Enter the USB from conception to finished product. Step by embarrassing step. No detail spared. So in-depth you'll need a snorkel... Let's get on with it...

Step 1: Getting Started

Project: Enter the USB was created by Kurtis Kronk for TheTechLounge.com. You can see the original article published online here.

Once I had successfully freed the USB drive from its lame shell, it was time to think. Whatever am I going to put this little thing inside? And so the search began. I thought about doing a better Lego mod - unoriginal; ChapStick - too thin (I've been informed that somebody else has made a ChapStick USB drive); film canister - too fat; USB cable shell - too short; gutted iPod - too spendy. Hmm... nothing on my desk was really striking me as a great idea. So the search continued. To the closet! As I rummaged through piles of miscellaneous electronics, cables, and computer accessories, I paused as I held an old keyboard in my hand.

What to do with a keyboard, though? The PS/2 connection isn't large enough to accommodate the USB drive, and the keyboard is a bit bulky to be useful as a USB drive. Think, Kurtis... Think.

As I stared at the keyboard, I noticed some tasty treats (well, they used to be tasty) peeking at me from between the keys. Gross. Ah, wait a second, the keys! Oh sweet, blessed keys.

There are a decent number of keys on the keyboard which look like they could be just big enough to squeeze a USB drive inside: Tab, Shift, Backspace, Enter, Delete, and +. After careful consideration and a quick coin toss, I decided the Enter key would make the best case for my custom USB drive. It sort of makes sense, after all; "Enter" your USB drive into the USB port, with an arrow to help the less technically inclined. Tab is just plain confusing, with the two arrows pointing in either direction, Backspace and Shift don't sound cool, and +... well, + isn't even a word. Stupid +.

Removing keys from the keyboard is easy enough. Using a small screwdriver you can gently pry them off. In my case, the Enter key had a bar stretched across its width to ensure uniform key presses - I just ripped it off. Enter key removed, I check to see if the USB drive fit... and it did - with a little room to spare.

Before hacking away at the Enter key, I decided to perform a practice run on the Backspace key (I only had one old keyboard to work with and didn't want to ruin it, after all). And I'm glad I did.

Step 2: The Practice Run

Picture of The Practice Run
Project: Enter the USB was created by Kurtis Kronk for TheTechLounge.com. You can see the original article published online here.

As I mentioned, I started with the Backspace key for a test-run. My plan of attack was as follows:

1. Dremel a notch into the side of the key.
2. Sand edges smooth.
3. Place the USB drive into the key.
4. Pour clear silicone into the key to secure USB drive into place and to allow the back side to be see-thru. However, for the practice run, I actually skipped steps 1 thru 3 because I was mainly concerned with how well the silicone would work as a filler material.

Step 4:

I was really glad I did a practice run. The day after I finished applying it, I was not happy with the clarity of the silicone; it was too cloudy. It was also a bit softer than I wanted.

So, I decided to use something else for the real thing: an industrial strength adhesive called E6000, which Brian has used in the past and recommended. That being said, about a week later I checked the silicone again and found it to be much harder. Apparently, it just needed more time to set. Still, the clarity wasn't quite as good as I wanted so I still planned to use E6000 in place of the silicone for the real run.

Step 3: The Real Run

Project: Enter the USB was created by Kurtis Kronk for TheTechLounge.com. You can see the original article published online here.

After the practice run, my plan of attack remained mostly the same, except for the first and last steps:

1. Remove clutter from inside the Enter key.
2. Dremel a notch into the side of the key.
3. Sand edges smooth.
4. Place the USB drive into the key.
5. Pour E6000 industrial strength adhesive into the key to secure USB drive into place and allow the back side to be see-thru.

Before pulling out the Dremel, I donned my protective gear. Kids, don't try this at home. I'm a trained, erm... heh... professional. Yeah.

Step 1:

The first thing I needed to do was get the little stub in the middle of the enter key out of my way, as well as the little pieces of plastic jutting out that supported that bar I removed earlier. For the stub, I bashed the key with a large stone. No... why would I do that? Safety in mind, I proceeded with my Dremel and fingerless gloves. The cutting wheel was used to cut in some notches first and then the grinding stone was used to actually remove pieces. Using only the grinding stone on plastic tends to melt it all into one big sticky mess. By cutting notches first, I was able to use the grinding stone pretty much exclusively to remove the little plastic pieces that supported the bar.

Step 2:

Before cutting a notch into the side of the Enter key, I grabbed a pencil and the USB drive to mark approximately how far I needed to cut. Once again I used the notch-then-grind method with the cutting wheel and grinding stone for the side of the Enter key.

Step 3:

I was able to clean it up pretty well with the Dremel, and then put on the finishing touches with some fine grit sandpaper. Care had to be taken with the sandpaper to not round any corners or edges, though.

Step 4:

With all the necessary cuts having been made, it was time to place the USB drive inside the Enter key. Fit was perfect, with a little bit of wiggle room.

Step 5:

Now for the fun: pouring in the E6000. The tricky thing was that this part had to be done a bit at a time, rather than all at once, to keep the E6000 from flowing out of the notch we just cut. So I started by filling the key up to the notch and then setting the USB drive back in place on top of it. I let it set for 24 hours, then added a bit more, and so on, until silicone was up to the top. Once I was completely finished, I let it set for another few days before messing with it, since I used a good bit more E6000 than your typical application.

Step 4: Conclusion & Photoshoot

Project: Enter the USB was created by Kurtis Kronk for TheTechLounge.com. You can see the original article published online here.

One extra finishing touch that I didn't anticipate was that, when the E6000 had finished setting, it was a little higher than necessary around the edges and wasn't totally flat. To correct this, I got the Dremel back out and used the grinding stone to roughly get the edges level. Then I grabbed some sandpaper of various grits (from 400 ~ 2,000) and got the E6000 surface flat and smooth to my satisfaction.

It isn't perfect and, if I had it to do again, I would have thought of a better way to make the E6000 nice and level without having to take any corrective measures after the fact. I've also thought about whether I should have chosen an opaque filler material, but then there is the matter of painting it to match the key. Overall, I feel Project: Enter the USB was a success.

If you've got a great idea for a USB drive mod, I encourage you to give it a shot. It's cheap, relatively simple, and lots of fun. Feel free to share your mods in our forums, or even submit your worklog to be considered for posting on TheTechLounge. Have fun!

When I opened my USB flash drive case, I was really surprised to see that the drive can fit in one of the small regular keys.

Done. Same Key. Metal bottom.
Here is how mine came out. I used a little sugru on the back and just pushed it in to the cracks. In the picture it looks pretty rough but I have smoothed it down some since then.

lol, 514 mb's? I have a 16 gig flash drive. And you can buy a 2 gig at wal-mart for 3 bucks. Great "ible" though! 5 stars.
He was being incredibly sarcastic, if you didn't realize. He got his for free at CES, where they were handing them out. That's why it is so small. That's also why he used them for this instructable

 i have an ancient flash drive and it won't fit into any keys except the space bar... but that would look weird. so i'm looking for one that doesn't involve keys.
You could probably fit a candy bar in a space bar. :-)
 probably... but that's not really relevant. xD
Who cares?  Everyone loves candy!
 i suppose.
CANDY BAR FLASH DRIVE!!!!!! probably not possible
definitely possible... until it melts, that is.

i haven't tried this yet, but i dont have a dremel, do you think i could just use a sharp knife or pliers to cut the notch? -aj
i used a soldering iron, lol, which probably wasn't such a good idea with the fumes and all but it worked quite well. just make sure u have a wet paper towel or sponge on-hand 2 wipe off the molten plastic. the dremel works much much better though
yeah, i've cut plastic and stuff with a hot glue gun
HOW IN THE?!?!?!?!?!?!?!?!?!?!?!?!?!



POST A INSTRUCTABLE ON IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
same. ive been using one to melt/cut plastic for like, all the instructables.

Possibly - depends how precise you want to be and how clean you want it to look.
okay, thx but do you know where i could find a cheap usb drive, incase i screw up that one, and it'll let me practice b4 i go and do this with my nice 4gig usb flash drive
staples sells little $5 64mb ones at the checkout counter also checkout microcenter.com they have loads of them. just buy the microcenter brand they're like 1 gb for 12 bucks which is pretty good
for 5$ i got a 4 gig microSD with an adapter
1 word - ebay
i just used an exacto knife 4 the notch it worked well and as long as you're patient and dont rush it, you'll get a clean notch

maybe a small hole on the top and one of those little plastic computer things that conduct light ? any idea what that thing is called?
Firbe optic? you mean the thing that extends the LEDs?
 They're called "light pipes"
yeah -- the plastic thingys ... i thought fiber optic was some totall different thing, but ur probably right
I call them fiber optic anyway. The principal of them is the same. I like the idea though... Would make the drike look cooler!
i also just found out about an led accessory called the light pipe a flexible one of those might be perfect for this instructable, especially if the flash drive's led is in an "uncomfortable" area to be seen clearly
drike?
XD. Oops, I meant drive.

my only problem is that i cannot find a keyboard to get the "Enter" key from. i would jack one from school, but i would most likely get charged for vandalism if i got caught. and also i dont have a keyboard that DOESNT work.
any ideas on where i could get a cheap or non working keyboard? Good Will possibly?

Just finished this, used a shift key :) I found that hot glue, while slightly less pretty allowed me to do it in about 20 minutes, i also used a band saw to cut the key to shape and then an extremely sharp chisel to take the remainder of the plastic out of the key. Once complete I trimmed the excess hot glue with the band saw once more. For a smooth finish, sanded with 320grit. The hot glue has the advantage of nicely difusing the LED that was on the USB drive I used as a donor, looks good. A tip for anyone who has access to them, older dell systems have ruberised caps on the molex connector which used to connect to a floppy drive, these fit the USB plug perfectly so make a great cover for an otherwise cap-less USB drive.

What brand of Flash Drive did you use? Or will virtually all of them fit into an "Enter" key?
Cool
