Persistence of Vision Project
Purpose: This portion of the project is a small prototype of the eventual 4 or 5 foot diameter
final device.Used to display images using persistence of vision effects.
The computer displays one column at a time as device rotates.
The human eye puts the columns together into an image (same as video, television, etc).
Schematic of POV
POV PCB Artwork
Here is the manufactured board under test. Lower clips are for programming the MCU.
Upper wires connected to clip across MCU is interface to LCD used for test only.
A previous version of the POV prototype
I printed the artwork (left) then made the board using the toner transfer method.
This was the first attempt at this project and the board worked after making numerous fixes.
Subsequent ("phase 2") boards (top of page) were sent out to a manufacturer for better quality.
