Immerse yourself in the captivating world of LED technology with our meticulously crafted DIY 3D LED Cube Kit. This kit features a PCB board constructed with RF-4 Class A materials, ensuring durability and reliability. The board layout is thoughtfully designed, with neatly positioned components and an optimal LED spacing of 2cm, tested and proven for optimal visual effect. Key interfaces are strategically placed on the side, allowing seamless integration with the included acrylic shell for a visually stunning display.

To help you in this project I have found the total assembly guide of this project on Instructable Circuits  Click Here 

Four key functions:

K1 key: Enter the mode selection, day, night mode control
K2 key: Enter the 3D8 PC mode (press the K1 key to be effective after power on)
K3 key: Enter 42 kinds of offline animation mode (press the K1 key to be effective after power on)
K4 key: Enter 14 kinds of off-line audio mode (press the K1 key to be effective after power on)

Three music keys features:

S1 key: Enter the music playback / stop control
S2 key: Enter the previous song / volume decrease control
S3 key: Enter the next song / volume increase control

Circuit design:

STC12C5A60S2 + 74HC245 + 74HC138 + 74HC595N
1. Integrated STC12C5A60S2 high-speed 1T microcontroller
2. 74HC245 buffer driver (cascade connection)
3. 5A high-current MOS tube driver chip (to solve the uneven brightness)
4. High-speed scanning chip and serial control cascade chip
5. Use a professional MP3 music chip
6. Use professional power amplifier chip 8002B

There are two ways to modify the pattern:

1. Modify the program (difficult, you need to understand programming)
2. PC computer software direct manipulation of the light cubic

Note:

1. Some parts in the kit may vary from the images shown, in terms of the shape of an LED or cable color but not to worry it won’t affect your project in any way.
2. The acrylic case Shown in the image is not included in the package you have to buy it separately

Features:

1. Can be inserted TF memory card to play music
2. Can be inserted U disk to play music
3. Through the audio line input and output music
4. Built-in MP3 music, the volume can be adjusted
5. Built-in music can be controlled by a button on the next song
6. Built-in 42 kinds of off-line stunning animation (plug in the electricity can run animation)
7. Built-in 14 kinds of offline dynamic audio animation (dance with music)
8. 3D8 on the machine mode (control animation)
9. 13D8 on the machine music mode
10. Infrared remote control function
11. Night, daytime control mode
12. PWM breathing light mode
13. Switch on the mainboard automatic detection mode
14. Photoresistor automatic dimming function (need to expand by yourself)
15. Shell size: 233 * 161 * 161mm
