Hi, I am a beginner. I quite interested in 3d hologram led fan. Any suggestions. How to make it. Are POVRay would be fine?
Link for the 3d hologram led fan.
Thank you.
Hi, welcome to the forum.
I hope that you don't get disappointed in Arduino, but that is not a hologram and it is not a project for beginners.
It is just a 2D display that displays video.
The frames to make something rotate are already calculated on a PC. The device just plays the video. The "holographic" claim is fake. They call it a "holographic effect", well, then I call it a fake effect.
As a beginner, you could start with a basic Arduino board. Those boards are too slow for such a project.
At Adafruit, they have a lot of tutorials. Tutorials for beginners, tutorials with ledstrips, and so on: https://learn.adafruit.com/
[ADDED] It seems to spin at 40 cycles per second. With an image height of 512, suppose the led update is 2000 per cycle (just a wild guess). So the leds should be updated 80000 times per second. Looking at the picture I guess that there are 320 leds in the bar. With 24-bit RGB values, the data rate would have to be 614 MHz. That is too high. They are cutting a few corners, but I don't know how they did it. The LPD8806 led driver can go up to 20MHz for the clock. Perhaps they don't use a single channel, and I think that they must use a DMA channel for the signals.
Nevertheless, the result is really neat, showing a picture without seeing a display. They did a good job for making such a fan display. It is also expensive. They make larger ones for even a better result:
Same question about the same fan display: https://forum.arduino.cc/t/diy-led-fan-display/628727
It's called "Advertising". 
thank you Kopel, I am very much interested in this Product. Not for "Advertising" though 
You need to be an expert to make this.
I don't know how they did it, so I have no clue.
I have not seen a similar project with an Arduino.
The examples with a fan displays and a Arduino are very simple compared to this.
