After a few hours of experimenting with the Arduino Pong, senior deign team member Yigal was able to get Mr. Bubbles on his TV. All the video processing is done with the Arduino and two resistors. There is an issue with the timing signal sent to the TV, but since we plan to use another microcontroller we don’t plan to figure out why. Nevertheless we’ve learned a great deal from this experiment. Great job Yigal!
Soon we’ll be focusing our attention on an 8-bit RGB to NTSC compositive video converter. This will be done a Digital to Analog circuit (DAC) and a NTSC microchip from Analog Devices (AD723). The same design they are using on the Uzebox.
