Introduction: How to Make a Fan POV Display

About: Awesome Electronics Tutorials, Projects and How To´s

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!

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

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

yes, but it can take hours,and you have to adjust the time every time you turn the arduino on

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