Led Cube 8x8x8 Circuit Diagram

For a small led cube 3x3x3 or 4x4x4 you might get away with connecting the cathode layers directly to a micro controller io pin.

Led cube 8x8x8 circuit diagram. The above image might not be very clear due to extreme compression. 3x3x3 led cube circuit design. Before i begun the larger 8x8x8 cube i decided to build a little proof of concept cube to test some methods of assembly. I also wanted the cube to be more interactive so i used the remaining six ports on the arduino to.

I settled on 4cm between leds resulting in a 28 cm 11 inch cube. The whole structure will be based on a wood board. Most led cubes i ve seen are limited by the led lead length. First part of design involves designing 555 timer as an astable multivibrator here we assume our required time period to be around 1 second.

For an 8x8x8 led cube with only 10ma per led you need to switch 0 64 ampere. The power supply i bought this one. This phenomenon is a feature of the human eye and is responsible for the illusion that a. My hope is that anyone who tries to re create this project can avoid the pitfalls i ran into.

In this project we will exploit the persistence of vision. To clear up confusion that i ran into when building this 8x8x8 led cube i ve gone ahead and re drawn the schematic. For a larger cube however the current going through this pin will be too high. I wish i would have went a little bigger.

Below is the new schematic. Ari dubinsky this led cube will light up any party. Several days depending on experience difficulty. The code is developed based on the work of chr from instructables.

The concept of persistence of vision. As the frequency of output signal given by f 1 44 ra rb c and values of c assumed to be around 100uf we calculate the values of both the resistors to be around 10k. The following image shows the complete circuit diagram of the 8x8x8 led cube using arduino nano. 512 leds driven by an arduino via eight 8 bit shift registers and eight mosfets.

Its a 120vac to 5vdc 10a. The party dazzler assembly time. If you want a clearer circuit diagram you can download it from this link. How the cube is made.

The dimensions of the cube will be 8 led by 8 led by 8 led for a total of 512 leds. I wanted my cube to be as large as possible while still producing smooth animations. How to build 8x8x8 led cube. Your friends will be mesmerized by its hypnotic effect as lights dazzle and dance in brilliant patterns.
