## Step 4: Making the Cube, Solder the Layers

We make the cube in 4 layers of 4x4 leds, then solder them together.

Create a layer:
• Put in the LEDs along the back and along one side, and solder them together
• Insert another row of LEDs and solder them together. Do one row at a time to leave place for the soldering iron!
• Repeat the above step 2 more times.
• add cross bracing in the front where the led rows are not connected.
• Repeat 4 times.
<p>anyone have C code for cube </p>
<p>chr why do you say in the code comments that the cube runs on 240 fps? In fact its running up to 1920 fps. The TCCR2 is set on a value of 5. This would make the prescale clock/128 instead of clock/1024. Not that it affects the cube... Just noticed it :P</p>
<p>Anyone know what programm used to make scheme like in step 7?</p>
<p>I'd use Fritzing</p><p><a href="http://fritzing.org/home/" rel="nofollow">http://fritzing.org/home/</a></p>
<p>Yeah, there's huge number of programms to draw such schemes, but I liked how it looks like in step 7 ;) But thanks anyway for reply.<br>If anyone know programm to draw exactly like in step 7 tell me ^^</p>
<p>does anyone know how to conceal the board and make it look more clean and presentable?</p>
<p>Nice! Definitely gonna make it!</p>
<p>Thanks</p>
Hey do u have programming of 4*4*4 led cube than please send me on my e mail<br>rk188181@gmail.com
<p>Hi </p><p>I m new to microcontrollers.</p><p>I currently have an Arduino Uno, would I be able to use this for a 4x4x4 LED cube?</p><p>If so, could someone please provide a wiring diagram?</p><p>Thanks in advance!</p>
<p>what programming language are you using??</p>

anyone experienced to offer some insight? i ve built many using arduino but i ordered one online a kit one and it came wirh no instruction. it runs off a driver and has sound sensor anyone know how to build it
I have been trying to find a tutorial for a bi-colored led cube. Do you have any idea where I could get some help with one in a 4x4x4? Thank you, Thom Mulford
<p>Right, so i placed RTC to show time, made enclosure from oak, finished with linseed oil, and placed mirror-plating as extra touch to create infinity-mirror effect, only in milder effect, it can be viewed in every direction</p>
<p>forgot to add, took hints/information from your bigger cube like that soldering jig, thanks!</p>
<p>Great project man! <br>Can u send me the code? &quot;HEX&quot;</p><p>Thanks!</p><p>giovanni_25_8@hotmail.com</p>
<p>Hai haii..</p><div>I made led cube 3x3x3<br> Obstacles that arise is when<br> - 3x3 layer 1 __ Is correct (all live)<br>- 3x3 layer 2 __ Is correct (all live) <br>- 3x3 layer 3 __ Is correct (all live)<br><br> Why when I combine layer1, layer2, and layer3 (Many LED DEAD).<br><p>I want to know why many LED die ???</p><p>Thank you very much</p><br><br></div>

<p>tell me how to generate code for 4*4*4 led cube.,.,</p><p> plz send me link for generationg code for AVR.</p>
<p>can i use a bc548 instead of using bc 338 transistor</p>
<p>Hello, I'm a free user and i wanna make this project. It is showing 11steps, are they complete or should i turn to a paid user?<br>Please tell</p>
<p>There are only 11 steps, free uses can see all the steps and comments, but can not download the project as a pdf, support the site and other things.</p>
<p>I am facing problem in compiling code . Which compiler or converter should be used to convert the above .c files to .hex files</p>
<p>Is Willar programmer fine for Programming Atmega16??</p>
<p>I put the .hex file on the desktop. I got in command prompt this message:</p><p>error opening 4x4x4_ledcube.hex: no such file or directory</p><p>Whats the problem?</p>
<p>I would really like to start this project; it looks so cool! Could I build the 8x8x8 with the Arduino Uno instead? It only has three ports so would it even be possible or would I only be able to build the 4x4x4 cube with the Arduino Uno? If I have to do the 4x4x4 cube, the wiring would probably be different and the code would remain the same though right?</p>
<p>Ungrounded layers sometimes light dimly:</p><p>I built a prototype of a 4x4x4 LED cube on a protoboard following the anode column/cathode layer approach with a set of current limiting resistors between the columns and an arduino controller and close the plane circuits with a set of 4 transistors in the software with an intent to only have a single plane on at a time. As I&rsquo;ve been testing my cube, I found that the fewer the leds that I have lit, the more pronounced an unpleasant effect is where other leds in an activated column (but unactivated plane) light dimly. I&rsquo;m really unsure why these leds would light up. The effect seems more pronounced with fewer leds being lit at a single time and totally disappears when all 16 leds in a plane are lit. Surprisingly, if I remove all grounding that closes a circuit, the activated column still lights with a diffuse lighting across the leds in the column. I&rsquo;ve <a href="https://www.youtube.com/watch?v=8O-Z7RAQRX8" rel="nofollow">linked</a> a video that shows the effect in the hopes that someone can help me understand what&rsquo;s wrong. net/net, I copied this design but hooked it up to an arduino</p>
<p>I have problem with the usbtinyisp. who can help me?</p>
<p>You need to install windows driver for your 'usbtinyisp' first.</p>
<p>I installed the driver and the usbtiny communicated with the chip. But when I try to setting the fuse, the programm tell me something like &quot;change 0 with ... (y/n)&quot;. I write &quot;n&quot; and from this moment the usbtinyisp can't communicated (connection failed, rc=-1)</p>
<p>i need to know how can i programme a cube led 4*4*4 without arduino !!!! plzzzzz</p>
<p>can you email me the program with &quot;mikropascal pro&quot; ? khouloudkalil@gmail.com</p>
<p>I built my ledcube thanks to your awesome tutorial, but saw this &quot;To compile the program, open a command prompt, enter the directory with the source code and type &quot;make&quot; on the command line. You should now have a file named main.hex in the source directory&quot; I tried that with the source files and I get all kinds of errors.

<p>Hi there, I want to make my LED Cube on STM32F4 Discovery board. It has Current Limit 150 mA and I have only 270 ohm resistors, which give </p><p>3V Ouput</p><p>11 mA per LED</p><p>177 mA when all 16 LEDs are ON. Will it damage my board?</p><p>Here is documentation link, p 77</p><p><a href="http://www.st.com/web/en/resource/technical/document/datasheet/DM00037051.pdf" rel="nofollow">http://www.st.com/web/en/resource/technical/docume...</a></p><p>P.S. Thanks for great instructable!</p>
<p>I made the cube with this board.</p><p>It won't damage the board. You will have only 150/16~9 mA per LED instead of 11 mA.</p><p>The side-effect is that one LED in layer will glow brighter then 16 in the same time.</p><p>P.S. sorry for my english.</p>
<p>i want to make a 5*5*5 led cube.what changes should i consider??</p>
<p>Hello ! Thank you for this awesome instructable.<br>I made a mistake while programming the microcontroller. <br>I ran &quot;avrdude -c usbtiny -p m16 -U lfuse:w:0xc9:m&quot; instead of &quot;avrdude -c usbtiny -p m16 - U hfuse:w:0xc9:m&quot; (the difference is &quot;lfuse&quot; instead of &quot;hfuse&quot;).<br>What's the command to reset the microcontroller ? <br>Thank you for your help.</p>
<p>Great Instructable!!!</p>
<p>Wahoo! It's finally complete! One of my inner bottom LEDs just died on me though :( That will be fun to switch out.</p><p>This instructable was great!</p>
<p>Time to move up to an 8X8X8 for your next project - and then on to the 8X8X8 RGB....fortunately got you I have instructables on both!</p>
<p>ok then how i can set the fuse bits .... plz tell me.....</p><p>i am using top2008(a universal programmer) burner to program the atmega......</p><p>thanx for the reply</p>
<p>Hello. Thank you for this great detailed instructable, it helped me alot. But i have a question, if all leds will be turned on, wouldn't they all consume (4*4*4)*0.012A=0.768A? And what will be with microcontoller, when its allow max 200mA at once?</p>
<p>Firstly - there are current limiters on the LEDs.</p><p>Second, only one layer is on at a time, max 16 LEDs</p><p>Third - LEDs are modulated - not ON with DC .</p><p>End result - very VERY little current draw.</p>
<p>From what I know the LEDs are not turn on all at once but one by one in a very fast rate nearly 200 frames per second, just giving the illusion of them turned all at once.</p>
<p>Thanks for reply. Thats right what i was thinking :)</p>
<p>i program the with given hex file but speed is very slow how can i increase the speed.</p>
