Introduction: Bluetooth Lego Brick

This is a take on the USBdrive, that was covered in Lego. Mine is a bluetooth adaptor that is covered in Lego, It is in total the size of one 2x4 brick.

Shown below are the bluetooth adaptor before and after modification.

Step 1: Dismantle!

Prize the plastic case open. There sould be four pieces, a metal USB bit, two plastic covers, and a circuit board.
Get some wire-cutters, on one piece of plastic, cut along the red lines, as shown below. On the second, cut the corners off so it looks like the second picture.
Piece the whole lot back together, and it should look somewhat like the last picture (Red being what it was before, Black being what is is now.)

Step 2: Chop, Chop!

Find two Lego bricks (2x2 little dimples each) They can be any colour :)

Look at the picture before you do any cutting!!!

Get a saw (I used a hacksaw) and cut two cuts down the side of one brick, as close to the edge as possible. Use pliers to twist and bend it 'til it comes out.

Use wire-cutters and pliers to take out the centre-piece.
A knife and file should be used to neaten it off a bit, until your bluetooth gadget will fit in.

Repeat with other brick.

Step 3: Glue, What a Sticky Situation.

Whip out some glue. I used polystyrene glue, for sticking plastic. Use whatever you think will work best; Araldite, Supa-glue, PVA, toffee, Hot glue (I would have used this, if I had a glue gun. Glue the plastic body into one of your bricks, with all the metal USB bit sticking out.

Leave to dry.




Leave to dry some more.

Step 4: Make Cap (With Another Lego Brick)

Find some foam, any old foam preferably quite spongy.

Cut two 1-2mm (thick)  pieces, big enough to fit on the top and bottom of the brick, as in the picture.

Glue them in place. The USB bitty should fit in nice and snug.


Step 5: Fin!

The USB lego bluetooth brick gadget dongle is now ready to be plugged into the computer! (once the glue is dry.)

Hi,
I didn't find any glue on mine, it just split open when pried.
As for the class, I am not sure what it is.. I just got it to pair with my desktop..
The antenna is the metal bit on the PCB that is covered by the case. This is visible in step one, picture one (the topmost part, not the four USB connectors)

I hope this is helpful.. I am sure there is an 'ible for bluetooth reception alteration that you could follow.

Cheers.
Will.

As long as you dont cut into the mechanism of the bluetooth device, it will still function. You can just buy one from DealExtreme.. They are super cheap and function well.

Very nice!  A few comments:
  • Dremel is your friend :-)  Hacksaws are for guys modding shotguns :-/
  • Why different colored bricks?  Why not two the same so it looks like a solid 2x4?
  • What about using epoxy or silicone instead of foam, and press-molding it so that the Bluetooth could still be used as a brick?

What's wrong with a sawed-off aka-modded shotgun?

You mean, besides getting you time in a Federal prison, and losing your right to vote permanently?  Short range, poor accuracy, tendency to misfire.

I made two of these, one black and blue, the other blue and black.. or a blue one and a black one. So I can make them look how I like.

I was using what I had lying around, so foam, model (polystyrene) glue, Lego bricks and a hacksaw, were all easily available components.

If you cut most of the plastic out of the case (of the dongle) and used hot glue, you could make it able to be used a a lego brick. Otherwise the case is too low for the brick to attach.

My Instructables are mere ideas, mymethord of doing it. Be creative. Create your own way. [:]|-[

Excellent answers!  Your last comment is right on the money, and I wish more people kept it in mind.

Thanks much for the comment on the case size issue.  With hot-glue or silicone you could do the press-mold, but I couldn't quite tell from the pictures that the space was so tight.

Again, a very cool little project, and well presented!
