Introduction: Awesome Led Cube

You never know when you might need a glowing cube to convince people you are from the future.

Step 1: Materials and Tools

To make this you will need:
A LED (preferably high power)
a 3 volt coin cell battery
a 100 ohm resistor (anything close to 100 will work)
a momentary or push button switch.
thin sheet metal
plexiglass

tools:
hot glue gun
metal shears
sharpie
saw
soldering iron

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.

Step 3: Lighting

Solder together the switch, resistor, and the led.
Duct tape the two wires that remain to the battery.
Hot glue the assembly to the inside of the cube with the button in the hole.

Step 4: Finish the Box

Fill the box with hot glue to diffuse the light.
Glue the final side on.

Step 5: Armor

Cut out of the sheet metal futuristic designs and glue them onto the cube.
Make sure that when you glue onto the button you don't stop it from being pressed down, and that it sticks out enough to be pushed down.

To give you an idea, Duck-Lemon made two templates. (last pictures)

Step 6: Time Travel!

Use the cube to slow, stop, or reverse time, or even turn ordinary technology into transformers. Your choice.

It looks the best in the dark.

I loved this idea, but instead of a single led I used a portion of an LED strip light, and left a small hole on the back to plug into power. It's not as portable, but you don't have to worry about a battery going bad.

why do you need a 100 ohm resistor?

author
wow_zakarum made it!(author)2011-02-09

The resistor is used to keep the LED from drawing too much current and burning its self out. You dont HAVE to have one, but it will last longer if you do.

Guys could we use aluminium foil for reflection instead of hot glue

I've killed a few LEDs because I wasn't smart enough to use one. You really need it if you don't want to waste supplies making these.

The original picture for the cube looks quite a bit like a Borg cube from Star Trek TNG. I'm not a trekkie myself, but I have a friend who is, so it will be so much fun to freak him out.

Try to make a hexagonal prism instead of a cube. It will look AWESOME!!

A number of people where asking about changing LED's I found this and thought these would do the job

instead of filling it with hot glue you could either use sandpaper on the led or the plexiglass to give it a frosted look

For the battery issue you could have a place you push down on that pops upen so it looks futuristicy.

One Idea. If the Battery in these things are empty, youll have to throw it away, I guess. How about adding a Supercapacitor and an inductive charger to it? So youll have to shake it if you want it to Light up. I thought that would be kinda cool and youll wont have to worry about empty Batteries!

make socket (hole or wath ever to call it ) for ac adapter :D u can easely racharge it :D

author

or, since the metal would be conductive, use two of the metal plates as charging contact plates?

author
trolomon made it!(author)2010-12-21

I think it can be added a little door to take out the empty battery

author
LogTrotter made it!(author)2011-08-03

Couldnt you just wrap black tape around the box then cut bits of the tape off instead of putting metal on it, it would be a lot easier?

I have a solution for anybody who thinks they will need to change the battery. Instead of using a battery to power the LED, you could use inductive coupling (a.k.a wireless electricity). However, this would only work if you wanted to place it on a table an light up, or something like that....

is there a way of drilling srews into plexi glass. i was going to make a music shelf and i thing glueing just isnt going to cut the job. i will then attach it to a wall socket and use this instructable to make it glow. i will cut a pattern to conserve the amount of usb's and the overall power being used.

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

author
The_Roamer made it!(author)2009-05-12

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

author
Demogorgon93 made it!(author)2009-05-17

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.

author
%5BaTRi0X%5D made it!(author)2010-01-25

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?

author
spraynard made it!(author)2010-02-02

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:

%5BaTRi0X%5D made it!(author)2010-02-02

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>

author
instruktejbls made it!(author)2011-07-07

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

author
spraynard made it!(author)2010-02-03

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.

author
spraynard made it!(author)2010-02-02

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.

author
zack247 made it!(author)2010-05-04

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

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

author
elyador made it!(author)2009-07-06

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.

yes but its thinner and shows any crinkles you might get in it.

Wait, isn't one side of the box not going to be lit up?

author
zack247 made it!(author)2011-07-07

nope, all sides will light up because the hot glue is diffusing the light throughout the entire box.
