Step 3: Creating the Vertical Rows of LEDs (positive)

Now the three horizontal levels must be attached from the vertical rows, which are the anodes.

In this case the level of the top is attached to the board where they made the holes.
Weld in the center of the cathode terminal, an enameled wire so that it is long to reach Veroboard.

The following relates to grasp the 2nd level which is fixed to the board, solder to all the anodes of the LEDs that were upright, overlapping about 10mm between these two levels.

After being welded, as can also weld the central cathode in order to reach the Veroboard.

With the lower level, the process is similar to the 2nd level

Here we have the hub already fitted and can follow links in the construction of Veroboard.

<p>I woud like to have the hex file for 3x3x3 cube led with atmega8.How much does it cost?What is the method of payment for the acquisition of the hex file?</p><p> Thank you!</p>
<p>sorry the delay..</p><p>you can buy the atmega with the code here:</p><p>http://www.g7electronica.net/pt/firmwares/113-atmega8-firmware-cubo-de-leds-3x3x3.html</p>
<p>thank you for your share. i will try to make led cube based you shared.<br><br>matur suwun kang mas.</p>
<p>can you give me hex for this only?</p>
<p>Is here any program for ATmega8 like showed here: <a href="https://www.instructables.com/id/3x3x3-LED-Cube/?ALLSTEPS" rel="nofollow">https://www.instructables.com/id/3x3x3-LED-Cube/?ALLSTEPS</a></p>
cool, but with more IO ports, this project become awesome, thanks for the tutorial
Very nice.. cool! <br>Great Job. <br>Could you share your code effects with me, please? <br> <br>
Very nice project I loved it <br>.
can u plz send the code fo the program?
this project is very hard. please give another preoject without programming or giving any thing.
Hi! G7Electronica.NET <br>How you programm ground for layers? <br>Thanks!
How large are the holes that you drilled in the board? I know they are LED sized, but how wide is that? I would like to know so my LED's dont slide around in the hole when i am trying to solder them.
I usually make the holes for component leads to 0.8mm in diameter, despite being a Veroboard this assembly, the default is always the same and 0.6mm might be too small.
You should combine this with this: https://www.instructables.com/id/DIY-3D-Controller/. <br><br>and play O's and X's with 2 color led's!! would be very nice
I spent several weeks making a visual basic program to simulate the effects before sending to the firmware, the code was all done in pure AVR and has 800 lines.
Very nice!!! Well done!!!!! ;-))
Obrigado! ;)
You know i already did an instructable on a 4x4x4 cube already in this contest.<br>not fair...
And I did a 3x3x3 cube with 50 effects... <br>Sorry if you think it is unfair!..Where is your fairplay?!.. ?:/
Good description of the manufacture.<br>I've been watching the video and is amazing, never seen so many effects together in a cube of leds and with so few components<br><br>Good job, 5 stars
At a level where the cathode of the LEDs have to be all together, bend these terminals to connect to an LED near, as there are only 9 LEDs per level, you can not make connections so that it is uniform. In the 1st photo you can see there are 12 horizontal links, not all are the terminals of the LEDs, but wires.
Wow! I really want to make one of these!<br><br>Can you explain what you meant when you said this?<br>&quot;As the terminals of the LEDs are not sufficient to make the 12 connections, you can use one wire tinned in order to be more esthetic final result.&quot;<br>
Very cool project! One of the best Led cube 3x3x3 I've seen out there! <br> <br>Your video is magnificent and the effects are many and beautiful! :)
