POV Globe with 8X8 matrix LEDs

You can build your own POV globe using 64 LEDs arranged in an 8Ă—8 matrix. You can use Max7221 controller IC connects to the matrix to light the LEDs in any pattern required via a simple serial interface from the PIC micrcontroller. Further, you can also add the IR pair that allows for detection of spin rate. Each revolution the IR beam is received that allows the PIC to sync the image with the start of rotation as well as time the spin so that the image fills the full rotation. Few snapshots of the design process is:

All the necessary steps required to build your own POV globe can be noted from the post here at Pyrofer’s Projects page.
