The most amazing thing about this project is the small number of parts. My boss joked that it involves 17 cents worth of parts and 1000 dollars worth of programming. But don`t worry -- the code is free to you! That means you can build this TV pong game in a very short time, or adapt the generic `video engine` portion of the program to make your own video-from-a-PIC project.
At the heart of the circuit is a cute one-transistor driver circuit that generates the NTSC voltages for white (1v), black (.3v) and sync (0v), depending on whether the PIC pin is driven high, low, or allowed to float. With careful programming, I was able
