Intro: 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!

My LED do not turn on although everything is wired correctly and the code is correct.
Does anyone have any suggestions as to what the problem is?

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 ?

jbumstead 6 years ago

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

attanayaka 6 years ago

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

RealAXZ 6 years ago

Will button cell work?

JasA1 8 years ago

i used one and it worked just fine !

RealAXZ 6 years ago

Can i use another type of hall effect sensor like SS49E or A3144 hall effect sensor instead ?

attanayaka 6 years ago

i dont have hall effect sensor

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

UtkarshC9 7 years ago

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

Masud Hassan 7 years ago

Can you code/programme it to act as a clock? Man it would be so cool!!

FamilyC1 7 years ago

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