Summary of A simple display that uses the POV to display messages in the air using PIC12F629 microcontroller
This article describes a simple rotating "Air Display" that uses the persistence of vision (POV) effect to display messages in mid-air. The system is controlled by a PIC12F629 microcontroller, requiring only a single button for power, message cycling, and shutdown. An algorithm was previously available for custom programming, though it is no longer provided.Parts used in the Air Display:
- PIC12F629 microcontroller
- Rotating display mechanism
- Button (for power, message change, and off)
- HEX file for programming
Download the HEX file HEREProgram the PIC with this HEX file. (Use right-click and "Save as")
UPDATE: Nov 6, 2005 - Algorithm is available. You can create your own program in any language using any microcontroller.
Build your own Air Display using this algorithm. Sorry, no longer available.
The operation is super simple and you don't need an user manual. Press the button to turn it on. Press the button to change the message and press the button to turn it off.

Quick Solutions to Questions related to Air Display:
-
How does the Air Display work?
The display writes messages on the air while rotating, allowing you to read them due to the persistence of vision. -
What microcontroller is used in this project?
The project uses a PIC12F629 microcontroller. -
How do I turn the device on or off?
You press the button to turn it on and press the same button again to turn it off. -
How can I change the displayed message?
Pressing the button changes the message currently being displayed. -
Is an user manual required to operate this device?
No, the operation is super simple and you do not need an user manual. -
Where can I download the HEX file?
The article provides a link to download the HEX file to program the PIC. -
Can I create my own program for this display?
