Introduction: How to Make a Fan POV Display
In this project I will show you how I transformed an ordinary old Fan into a LED POV Display which can present you light patterns, words or even the time. Let's get started!
Step 1: Watch the Video!
The video gives you all the basic information you need to build this project. In the next steps though you will find all the files I created which you can use to create a similar POV Display.
Step 2: Order Your Parts!
Here you can find a parts list with example sellers for your convenience (affiliate links).

Step 3: Create the Wooden Stick!
Feel free to download and use my design.svg file to create a similar wooden stick that I used in the video. Make sure to open the .svg file with Google chrome and print it out without any margins.

Step 4: Build the Circuit!
Use the here presented schematic and reference pictures to create the circuit.
Step 5: Upload the Code!
When uploading one of the three Arduino sketches to an Arduino Pro Mini it is necessary to use an FTDI breakout. After a successful upload the project is pretty much complete.
Step 6: Success!
You did it! You just created your own POV Display!

Question 4 months ago
Bro how can I program to get images & videos in 3d led fan can you please make a reply soon...

I think this is a very good guide to get started with this topic.
I recommend to use 7 LEDs, so the characters can be taken from a LCD display (20 x 4 or similar). For this you can find countless examples and libraries. It provides a better resolution and the code can be optimized.

I made it , but there are not all the letters in your code , how do i code them ?

Thanks for creating a very clear instructable. I didn't know about the hall sensor, and I used it for another spinning electronics project.

no hall effect sensor. i have reed switch.how to connect it.and how to programe it

Hey great scott. Regarding the battery management, do you have a recommended procedure/charger to recharge the battery?

Hey great scott.i just wabt to ask that can i use a 9volt battery instead of the lipo battery???

If the arduino mini can support it, and keep in mind that it will ad a lot of weight to the wooden stick

Can you code/programme it to act as a clock? Man it would be so cool!!
Reply 5 years ago
yes, but it can take hours,and you have to adjust the time every time you turn the arduino on

cool!

I'd love to see this on a ceiling fan with RGB LEDs in time to music.
