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.
