LED Cube 3x3x3 with Arduino

[ichica1234]

fun..

[greenoakst]

didn't you use the transistors to power leds from external source?

[brionwolf]

@greenoakst Hi Greenoakst,

Each of the 9 columns of the cube are the daisy chained positive contacts of the LEDs in each column. Each of the 3 levels of the cube are the connected ground contacts of the LEDs on that level.

The transistors are simply switches for the grounds of each level helping to complete or disconnect the circuit. In this video, the cube is connected to my computer via USB for power.

I hope I answered you question, if not, feel free to reply.

@brionwolf can i get the copy the code of this led cube...please..

[brionwolf]

@christy00900 Hi Christy,

If you look in the description of the video you'll see a couple of links. One goes to the project page. The other link goes to the instructable I used. You'll find the code there.

Hope that helps!

[lanjore]

cool!

[brionwolf]

@lanjore Thank you!

[ScaniaMF]

Please upload the code! Would be very nice^^

[brionwolf]

@ScaniaMF Hi ScaniaMF,

The code I used in this example can be found on step 4 of the instructable I used. Links to the instructable and the finished project ("Keyboard Cube") can be found in the video's caption.

Good luck!

1. make like 100x100x100

2. make it with colorable diodes

3. connect it to your computer

4. watch movies on it!!

[brionwolf]

@IAMmrDDD If you buy me the 1 million LEDs needed for the project I'll do it! ...3D glasses, eat your heart out!

[makrisj]

@brionwolf OLED HD displays already have more than 6 million OLED's.

The problem when it comes to real 3D Holographic displays of real-time captures lies not on the display but at the capturing device. We need a volume scanner to get the 3D image. A valid approach could include advanced optics probably of electro-organic lenses able to move at extreme speeds with ultra-narrow field depth, but it will probably remain on the design table for years to come.

@makrisj

Do you know where can I find more about this makrisji?

Thanks

[makrisj]

@rotalmora please ask brionwolf, the uploader. Thanks!

[makrisj]

@makrisj google lytro camera.

Well, it looks like we are one step ahead on the right direction. A camera can capture raw light and post-process it for focusing. This is a leap forward for 3d holography, but I guess noone has even considered about it yet.

OMG, they don't know what they designed! lol

[raianlokoporcorintia]

publishes the technical diagram please. would like to ride!

[brionwolf]

@raianlokoporcorintia Hi raianlokoporcorintia,

Helpful links can be found in the caption of this video. God luck, have fun!

[MrTony95]

Hello, how do you control the levels of the cube? because I think it is necessary to control the gates of ground. thank you ;)

[brionwolf]

@MrTony95 Hi Tony,

I'm glad to help. Each level of the cube is controlled by a its own transistor. Each transistor is connected to the ground wire in black, its corresponding level, and an input on the Arduino to control it. In the video's caption, there is a link to the Instructable I followed to build this cube, and a link with more pictures of my completed cube.

Good luck!

[hichem337]

Salut,

Je recherche des infos, guides, conseils, bref tout ce qui peut se trouver pour que je puisse fabriquer moi-même ma propre led cube :D (8*8*8 avec des LED tricoleurs).

Je trouve que c'est magnifique en deco intérieure et je serai fière de la faire moi-même, étant un peu bricoleuse de nature :) merci d'avance :)

[brionwolf]

@hichem337 Je n'écris pas très bien en français, mais je vais essayer. Un cube 8x8x8 n'est pas facile. Il ya des links dans la légende de cette vidéo qui pourrait vous aider plus, mais je ne sais pas si ces guides ne fonctionner sans changements à la conception du cube. Bonne chance, je serais intéressé de voir ce que vous faites.

[9165rab]

hey i am a naive in these electronics so you might find my question amusing...but what is that little blue circuit ...and is it connected with a computer...what programming language did you use??... :)

[brionwolf]

@9165rab I'm glad to help. The little blue circuit is called the "Arduino Duemilanove" micro-controller. I connect it to the computer to program it using a USB cord. Once it is programmed, I only need to keep it plugged in for power. The programming language is called "Arduino" you can find more about it on their website "arduino.cc". Have fun!

[thegoodhen]

@brionwolf Actually, I believe the language is called "wiring", but whatever. :D

[brionwolf]

@thegoodhen Yes, Arduino is indeed based (read: heavily) off Wiring, both of which are based off Processing, WHICH is a totally-completely-sweet-aweso­me-sauce language, especially for the beginner programmer.

[thegoodhen]

@brionwolf Indeed. In just 1 day I have Arduino, I was able to make like 5 projects! O_o.

[linemanlv]

101 ;)

[brionwolf]

@linemanlv I'm embarrassed to say I haven't been keeping track... Whhere did the 3 dislikes come from!? hmmm, I think I can live. Anywho, thanks for being 101, I'm glad you like my shiny cube!

[linemanlv]

@brionwolf dude teach me how to do one,please? :D

[brionwolf]

@linemanlv I was thinking about upping the ante and making a 4x4x4 cube, maybe I should make a tutorial video with it. >.> As for teaching you to make this one, alas, all I have to offer are a couple of links in the caption that might help. *offers links*

[garnet5811]

100th like :)

[brionwolf]

@garnet5811 I do not have much to offer but please take this badly hand rendered ASCII chocolate chip cookie as a sign of my appreciation: ooooooooooooooooooooooooooooo ooooooooOOOOOOOOOoooooooo ooooooOoooooXoooooooOooooooo ooooOooXoooooooooXooooOooooo oooOooooooXooooXoooooooOoooo ooOooXoooooooooooXooooooOooo oooOoooooooooXoooooooooOoooo ooooOooooXooooooXoooooOoooo ooooooOooooxooooooooOoooooo ooooooooOOOOOOOOOooooooo oooooooooooooooooooooooooooo

[brionwolf]

@garnet5811 And that didn't even render correctly. Darn!

[brionwolf]

@Hapticpianist Thanks, have fun!

[solidshark91493]

@brionwolf You didnt use the transistors?

[brionwolf]

@solidshark91493 Thanks to the video quality, the 3 transistors look like a thick black line to the right of the front most resistors. If you want to see better pictures head to my "keyboard-Cube" project page at brionwolf[dot]com. You can find the link in the video's caption.

Enjoy!

[JohnMinigun]

it doesnt look lika cube , cube has 4 edges so 2x2 "is better" xD

[brionwolf]

@JohnMinigun Sir John MiniGun, I do believe you are either (A) stuck in a 2dimensional universe, (B) watching too many 3D movies and think the rest of the world is flat, or (C) the video just makes the cube look like a square. I assume it's "A" because what else would it be? So, please modify your phase variance using the T19 Spectral Grafter you most likely have with you, We can use that to pull you back to our dimensional time/space

[stephaniecamps]

cool stuff

[brionwolf]

@stephaniecamps Thanks!

[regretsmyl]

i have an idea for a simple version without so many effects but will be nice with tiny points of light.... My idea is 5 panels of plexi glass in cube shape and fiber optics thru panels...

Can you imagine? I will make a test on small scale first..

[brionwolf]

@regretsmyl I am indeed trying to imagine. Sounds pretty neat. Putting fiber optics in just about anything makes it a billion times cooler. Do it!

[regretsmyl]

@brionwolf Thanks. I will.

I hope you have already saw my fiber optics Stars in my library

video.

Video can't show how amazing it is.

[strictpolicy]

are you going to insulate the LEDS wires? how would you go about doing that?

[brionwolf]

@strictpolicy I didn't even consider insulating the wires on the LEDs. The way the actual cube is constructed means there is little chance to get a short unless you're sloppy with your solder. I also felt keeping them bare actually made the armature disappear from view in a way.

If you really wanted to insulate the leads you could do a number of things. If you have a lot of thin gauged heat shrink you could cover each of the leads on the 27 LEDs.

Hope that helps!

- Brion

[MarcosRamirez349]

@strictpolicy you can use paint all right? I can't remember what type of paint we used at work to cover al the bus from transistor to others..... if that gives an a idea

[hyper080]

@strictpolicy liquid electrical tape is the easiest thing to use

[brionwolf]

@strictpolicy I'm going to agree with @Hyper080 on this one.

[XxALEXxX83]

how i can make it ??? pls answer ! thanks

[brionwolf]

@XxALEXxX83 Take a look at the caption, I linked to an awesome instructable I used in making this cube.

[atulmadhugiri1]

you should make the middle one yellow and top one red and make it respond to music. I think ill try this today. Thanks!

[brionwolf]

@atulmadhugiri1 Actually a friend of mine made an all green one that responded to input my is computer mic. It was ere watching it as we critiqued in class.

[9110707]

а я купил тут yaport.info прикольная тема! за 900 руб

[MrBry329]

now i know how they make those cop car toys light up and do all that

[brionwolf]

@MrBry329 I never had many cop car toys, I did have this old jet fighter toy with "EXTREME LIGHT AND SOUND ACTION" <-- How 6 year old me remembers it I'm sure.

[brionwolf]

@rich202100 Hi, You can find the plans and what I did with with finished cube in the description under the video. under "LINKS:" Hope that helps.

[tommyg5150]

I built the led cube just liked you did in the video. But I am using the minipov3 kit. I have 9 wires from the cube and only 8 spots for the leds in the kit. Any ideas?? any help?? Thanks Tom

[brionwolf]

@rich202100 admittedly I used this great Instructable by Gzip to build the cube, then used a processing library to map all the pins. The link to the instructable and the project's page on my website are in the video's description. Hope this helps!

- Brion.

[ipadize]

can i run the arduino with battery and without cables?

[brionwolf]

@ipadize I'm afraid you'll need at least a couple of wires. the Arduino doesn't have a battery on it, but it does have a USB connection as well as a 2.1mm plug. With the plug you can make or acquire an appropriate AC-to-DC adapter to plug into the wall, or a very simple battery setup. The "Arduino Playground" website has a nice tutorial on making one for a 9v battery. arduino.cc/playground/Learning­/9VBatteryAdapter

[ipadize]

@brionwolf thx

[wingwolf]

gostei!!!

[brionwolf]

@wingwolf obrigado!

[tommyg5150]

any pictures of the bottom of the circuit board where the leds are mounted??

[brionwolf]

@tommyg5150 I just uploaded a couple images of the underside to the project's page on my site. You can find the link in the video's description, as well as a link to the instructable I used to built it.

Hope this helps,

- Brion

PS, I'm embarrassed to say the bottoms isn't put together with the same meticulousness as the top.

[tommyg5150]

very clean install. Where did you find the colored ide cable??

[brionwolf]

@tommyg5150 I'm afraid it's not IDE Cable, just red wire I bought from radio shack in a pinch and then very neatly tapped together with blue tape. Does look colorful through!

[ivanbg13]

where can i buy this things?

[brionwolf]

@ivanbg13 I bought most of my components from SparkFun electronics. A simple Google search will bring them up. If you want more buying options, the official Arduino site gives you a number of other sellers. you can find them at arduino.cc

[sorlaker000]

awesome!

[randumnumber]

Mind sharing your code? I would really like to look at it, i have built a cube but am having trouble with the coding to make it fast enough not to blink

[danimal511]

very nice dude
