Step 1: Get your stuff

Picture of Get your stuff
Hello All.

Yes, I know. You've probably seen this before, and your probably saying that this wasn't my idea. So no, its not my idea. I just couldn't find it on instructables, so I decided to post it as a reference for the rest of us.

You will need:

A USB memory stick (the thinner the better, it should be thinner than the lego piece)
Some Legos (either 2x4, 2x8, or whatever size you need to fit the memory stick.
A dremel, with a sanding part and that spinner-disc thingy part (see picture)
Hot glue

Step 2: Get your USB and empy out the lego

First of all, remove your USB stick from it's case. To do this I simply used a knife to pry the two halves open, but it should vary from case to case.

Next, use the rotary disc to remove the insides of your lego piece. I did this by first cutting the middle out of the end of the lego, and then working my way down to the end. Remember to only open up one end of your lego, and only make it as wide as the USB port.

The disc is the most useful tool, because you can make cuts length-ways into the bottom of the lego, without going through the top. After doing this, tilt the disc at an angle then cut of the extra pieces of plastic.

Next use the rotary sander to flatten out all that you couldn't get using the disc. Also, you may need to thin the walls of the lego, in order to allow the USB drive to fit. The sander is useful for this too.

wont the glue affect the usb?
Surprisingly no.
Not too surprising... Hot glue is an insulator. Try covering up one end of a battery with hot glue, then hook up 2 wires and a flashlight bulb. It won't work. The only thing you should worry about is the hot glue burning the circuit board or overheating it.
Yeah, I was worried that the heat would mess it up or something, but it turned out okay.
As long as you only apply heat for a short amount of time (no more than about 4 seconds continuously), the board and components should be fine. After all, some soldering irons work at 400 degrees centigrade but they don't damage the circuitry.

They sell tiny 512 MB drives at meijer for only $10. I think I will get one and make a lego flash drive out of it.
I got a memory stick at staples for 10$ (2 GB)

one last thing MEGABLOCKS SUCK
i got a 64 gb for $30
watch out, some cheap chneese large usb drives are actualy smaller then they say.  they have a spectal program imbedded into them, that tells the computer that it is larger then it really is.  there is an instructable aroung here about how to check if it is fraud.
i got one at micro center for $8 2gb

Try and find wafer usb sticks as they take less effort to insert in to one of the bricks. I used a 2X4 for the stick and a 2X2 for the cap then simply inverted flat 2x4 and 2x2 for the bottom coverings.

If you use plumbing goop it takes 48hours to fully harden but holds like crazy. Then if you use some small super magnets (rare earth) and insert them in to the inside of the lego casing while the glue dries; you get a cap that holds itself on.

I attached the pic with dimes simply to show the magnet placements. Also I would suggest you make a template or use slow speed on the dremel to avoid making a bumpy line on your holes.

Here's mine! It has a new led (shines as a new stud) and a keyring!
it's very grate.

No. I've done like 4 of these. The glue doesn't affect it in the slightest.
Megablocks suck. Period.
Uhhh guys you do know that megablocks are a branch off of legos dont you? Its to make competition without having to lose money.
No, your thinking about megablox, there for very young children, because they are much larger, so the children can't swallow them, megabloks are made by their own company.
interesting theory... so they sued themselves then? Sounds like a very expensive cover for their conspiracy! Just yankin' yer chain a little bit Wiimote Master -- Actually, Mega Bloks are manufactured by Ritvik Holdings which was sued by LEGO Canada. They are indeed unrelated companies. And MegaBloks do too suck. Twice.
Indeed , they suck
Who cares? Megablocks still suck
ultimately to all extent

Megablocks do suck, but that's probably why he cut it up...
I'm trying to make a memory stick out of a cast of a wedge of lime. I will fill the cast with clear resin and place the memory stick in, and wait for it to harden. When the lime wedge is hard, with the memory stick inside,i plan to cut off the end of the wedge for a lid, so that the male part prodtrudes out when the lid is taken off. Does anyone know how i could cover the end bit of the memory stick so the resin doen't affect it? If this makes any sense i'd be glad of any ideas! Thank you!
It won't be pretty, or for that matter a particularly accurate fit, ("But -- it just might work.") do you think thin plastic sheet, like cling film or a nice flat carrier bag section would resist the resin long enough for the resin to harden/cure? Don't forget to test it before you try it for real! Hope that helps.

Megablocks always come apart.
yeah, when my friend and I used to play with legos, whenever we found one, we'd throw it in the trash. evidently he got a set of them.

I think it's alot better to have one of those thin pieces cover the bottom, and poke a hole through the brick so the light can shine through. That's what i did.
