NEW! (11/14/2014) This kit has been upgraded to a professionally manufactured circuit board and the price has been reduced to only $9 per kit. (And for educators, a discount price of only $8.00 per kit.)
This Persistence of Vision (POV) toy is simple to assemble and fascinating to play with. It is a good introduction to digital electronics and soldering. It works by flashing each column of “pixels” in rapid succession producing the illusion of text in mid-air. You can program in your own messages using two push-buttons. The message is saved in “Flash” memory and will remain in the MCU’s (PIC16F628a) memory even when powered off. The message can be changed as often as you like.
This POV toy is similar to the MiniPOV3 with a few important exceptions:
* Button cell battery - more portable. Easier to mount onto a bicycle or other spinning object.
* Change the message without using a computer.
* Less components to solder in.
* Less expensive ( Now only $9! )
