Awesome led cube

Step 2 The box

Cut out 6 squares of equal size from the plexiglass with a saw.
Use the hot glue gun to make them into a box. Leave off the last side for now.
Drill a hole in one side of the box, make the hole large enough for the button on the switch to be pushed through it.

What are the dimensions of your pieces? Are all the pieces the same size?

[The_Roamer]

If you want a "CUBE", yes... ; )

[Demogorgon93]

No, they can't be for a perfect cube. You'll need: (1) two squares size n x n. (2) two more size n x n - d (3) two more size n - d x n - d ... where d is the thickness of each square.

[spraynard]

Sorry, I hate to nitpick, but wouldn't it be one at n x n, two at n x (n-2d), and two at (n-d) x (n-d)?  You have to account for the thickness of the squares twice if d equals the thickness of one square.

[zack247]

so to put it simple, subtract the width of the 2 end squares from the length of the 4 side squares and you will get a nice, even cube

Okay, so what would the volume of the cube end up as?

n+d^3?

And how big does the sheet to cut from need to be?

[spraynard]

Technically it should be n^3.  If the main face that you are having to fit the other pieces to is n x n, then each side of the final cube will equal n.  Therefore it should be simply n^3.  If you want the interior volume, then it would simply be  (n - 2d)^3, where d is equal to the thickness of one side.
Hope that helps.

I think if i replicate what is explained in the comment below by elyador, a top down view would look like this:

[[aTRi0X]]

Pieces 1, 2, 3 and 4 are vertically standing pieces n x n.
Piece 5 and piece 6 (not visible) are (n-2d) x (n-2d).

b>Diagram is not to scale, btw. My pieces wont be that thick compared to length</b>

[instruktejbls]

5 and 6 could be all over: (n+d)^2

[spraynard]

well...technically, if your 4 edge pieces are equal to n, then by your diagram the end caps should be (n-d) x (n-d) instead of n-2d.

"HPkingcharlesxv �;!F�&^�bgKbµ�ƒhµJ�����^�ZfedZb?(??????-) quite obviosly, i mean how could it possibly be anything else

[rebekeplex]

Pieces can all the same dimension. Just have to assemble them correctly.

[elyador]

I'm not so sure. All the lateral pieces could be the same size and overlap at the edges, but then the cube would be taller than the cube is wide--by the thickness of the plexiglass x2--because one base sits on top of the lateral side's and the other one is underneath them. this wouldn't matter all that much if the plexiglass was thinner and the cube was larger, because the difference in the sides would not be obvious. To be a perfect cube, the bases would have to be a little bit smaller (the width of one plexiglass pice subtracted from the length of the sides) to fit inside of the four lateral panes.

[insaneRD898]

actually,I made those using cd cases,the transparent one
saved money,  ;p

[sparky9898]

Just to help clear up the whole dimensions problem, as long as you use the diagram someone posted below then 4 middle peices should be the same, and the other 2 top and bottom peices should be the same.  

The 4 middle peices should be (n-d) x (n-2d) ; n = the length or width,  d = thickness of sheet. 

 If you so this then the top and bottom peices of the cube should only have to be n x n.

umm can there be a different glass or other like plastic or normal glass?

[carrot181]

well unless you have a effetive glass cutting method than yea you probley could. but normal flat glass is hard to come buy unless you got a spare window.

[mikotaku]

definitely. as long as it can stand the heat of a glue gun.

[15112]

wow peaple

[dava_2]

I have few qusestions..
1. Where to buy that plexiglass?
2. Can i use a Super Glue instead hot-glue gun?
3. What resistor is best to use?

[roblin90]

When you say plexiglass, do you mean acrylic plexiglass?

Also how thick was the plexiglass that you used and could it be easyly cut with a scroll saw?

[pumpkinpiiekat]

What size does the plexiglass have to be?

[applecake]

3 cm.

[astrong0]

You could make it fifteen feet by fifteen feet if you really wanted to

[pumpkinpiiekat]

Realy? I asked because my friend is making it for our technology class at our school... and I was wondering because hers looked big compared to the picture...

[astrong0]

well the only thing that i would be concerned is the thickness because you could have the light come on only if you put it on a base that has a magnet on it that would be pretty cool.

[pumpkinpiiekat]

You confused me on that...

[astrong0]

i mean to use a magnetic relay switch

[pumpkinpiiekat]

... i don't know what that is... i am only in middle school!

[astrong0]

umm google magnet switch and ps i'm  a sophomore

[Zaphod Beeblebrox]

i kow what it is im 12!

[Gage987]

okay lets be more generally

i have heard that before and i have been born

[astrong0]

...you're right most people have...

[Zaphod Beeblebrox]

?

[pumpkinpiiekat]

???

[TFElite]

Freshman FTW!
I've got everything but the Metal (Soda Can)
And an LED (radioshack)

[astrong0]

just rip apart an old remote. the ones that light up when you push a button

[BraisedDuck]

the plexiglass is freakin' hard to cut....

[3xpl0dingR4pt0r]

Not really, i used a tablesaw and it worked like a charm. It took me like 2 minutes to cut like 20 squares.
