Yes, I have a new version of NBTV converter. It uses latest AV Foundation frameworks and should run on 10.10 or later. It generates both monochrome and color video at 30 to 128 lines with 6.25, 3,75, 12.5 and 15 frames per second. For higher rates and more than 32 lines sound card needs to support 96000 samples per second sampling rate. Arduino part uses 96X64 full color OLED display and capable of displaying 32 and 64 lines video in B&W or color at up to 15 fps. This morning I tried a larger 128X128 pixel display in hope to do 96 and 128 lines, but it turned out to be too slow compared with smaller display, so that was a failure. I am attaching an Arduino sketch and NBTV converter zip files if any one interested to play with. Arduino Due board uses its internal ADC converters to sample video, so interface is very simple.
