Introduction: Keyboard/Sudoku Rubik's Cube...dead Computer Contest

Tired of the normal Rubik's cube challenge?   Have the keyboards from a dead computer?  Well, here is the thing for you!  The Keyboard/Sudoku Rubik's cube!

i got the idea when i popped off a key from my key board and looked at its shape, and it fit perfectly on my Rubik's cube

*thanks to the editors for the feature*

Step 1: Materials

For this instructable you will need the following:

a Rubik's cube (maybe the one that your stickers are falling off of  =D
a tube of epoxy, or other strong plastic on plastic glue (I used clear drying)
guitar pick or razor blade
two (2) keyboards, one black and one white
small fan
fingernail polish remover/goo-gone or similar product (to remove residue from stickers)
thin wood or cardboard
flat head screw driver
needle-nose pliers
rubber/latex gloves
tooth picks
face mask (cause the epoxy smells)
six (6) plastic bags
spare thin cardboard, or something else to mix the epoxy on
dremel power tool (recommended but not necessarily needed)
roll of paper towels
lots of time

Step 2: Preparing the Cube and Keys

remove your old worn out stickers, a guitar pick can be used or a razor blade (dont cut yourself!)
remove any residue from the cube with finger nail polish remover

you will want to pop-out all three sets of number keys from both key boards i.e. the Fkeys, the Numpad keys and the 'regular' number keys (above the top row of letters)

the backs of the keys could have plastic that protrudes beyond the base of the key.  If this is the case, you will have to remove it.  When i did mine, the white keys just had to 'prongs' that were thin.  I just pulled them off with the needle-nose pliers.  The black keys had a circular protrusion.  Here i tried to pull them off with the pliers, with little success.  I could do it, but it took a ton of effort.  I borrowed a dremel tool, from my grand-dad, and they got sliced down to size.  

*As a note, my father took the old computers to a recycling center, especially for technology, so i dont have pictures of the original keys i used, but i did get my hand on a new key board.  These keys had a small protrusion that was quite easy to take off.  Not all keyboards are created equally, you will have to use a method that is most effective for your situation.  For these keys, a razor blade worked well.

for the sake of organization, i kept all 9 pieces of each 'set of keys' in individual plastic baggies

Step 3: Gluing the Keys to the Cube

epoxy can be dangerous if you inhale too much of the fumes or get it on your skin, please use caution when gluing!

First take one of the plastic baggies with your set of keys, and lay the keys out in a square pattern.  I started with the number 1 key in the bottom left hand corner.  basically, it will look like the keys on a calculator, or the Numpad on your key board.

Now we need to disassemble the individual pieces of the top layer of the cube. I find that if you turn the top layer of the cube 45 degrees then try to remove an edge piece you will have the easiest time.  I then put the cubies into a square like the keys and set them side by side for easy access.

see the pictures for visual on how to remove the cubies

At this time I turned on my little fan and put on my 'fume mask' and gloves.
As a note, I only worked with one face of the cube in any one gluing session.  I found, even with the fan and the mask, the fumes were too much for me.

Mix the epoxy and then apply it to the cubies, but you only need to put epoxy on the perimeter.
I found that a tooth-pick works best for applying the epoxy.  Then carefully place the keys onto the cubies, making sure that if any edge of the keys was not hanging over the edge of the cube.  It is vital to the rotation of the edges, when you go to play with the cube, that nothing blocks the sliding motion of the sides.

Step 4: Letting the Epoxy Dry

After I had the keys on the cubies, i put them in a clamp to dry.  I placed a thin piece of wood between the cubies and the clamp so I could put 4 under one clamp and so the pieces wouldn't get damaged.  I used a wooden saw-horse, but i'm sure the work bench you have would work just fine.  Clamping is not critical, as the center piece wont come off and it would be a hassle to try to clamp it, but i felt i needed to add pressure to the pieces so they wouldn't slip.

After the epoxy dried, i repeated steps 3 and 4 until all six sides were completed.

Step 5: Important Details/Finished Cube

After its dry, all you need to do is lube it up and you'll be ready to go!!

Some Notes
I kept the 3 white sides so they converged at one corner, and same with the black (at the number 3)

The cube is actually more like a picture cube than a real sudoku cube, it just looks like you will need extra algorithms to solve the cube:
     M' U' M U (5 times)...turns top middle clockwise 1, and front middle counter clockwise 1
     M U M' U' (5 times)...turns top middle counter clockwise 1, and back middle clockwise 1
note-M' is away from you
Hang on, this one is LONG
     R U R' U R U U R' U R U R' U R U U R' U R U' L' U R' U' L U U R U' L' U R' U' L...turns top middle 2 times
thanks to abunai59 from Youtube with the video "How to Solve a Picture Rubik's Cube!!

*EDIT: here is a way shorter algorithm for rotation of the top middle twice
U R L U2 R' L' U R L U2 R' L'

thanks go to Gonazar for the short one!

i use them, so they work
final notes
the cube even stands on its own
i had keys that were long, from an ergonomic keyboard, so i used the dremel tool to cut them (see picture 4)

thanks for reading, good luck, post your picks, and leave your comments and questions if you need anything!
