We’re slowly getting more of our kit documentation up on Instructables, here’s the MiniPOV kit – this is an inexpensive Persistence of Vision (POV) toy, which is designed for beginners in electronics. You swing this little thing around to reveal a customizable message or image through it’s 8 red LEDs. It has 4 holes for mounting on bikes, fans, and anything else that swings around. You can purchase this kit from the Make Store.
This project is the third revision of the MiniPOV. This version is nearly identical to the last version, MiniPOV2 but uses the serial port (possibly with a USB/Serial converter) instead of a parallel port, for programming. Because the programmer is built into the kit, one does not need a special “microcontroller programmer”. This version can be used with PCs (Linux/Unix or Windows) and Macs (running MacOS X and with a USB/serial converter).
