#1, #2 tjHow, j:
Keep in mind an RGB peggy (assuming 25×25 pixels) would be the equivalent of 3 times as many LED’s. It’s possible, but it gets a bit more difficult. Also, some calibration would need to be done to get the RGB levels equivalent (green is usually brighter then blue and red) And, it would be MUCH more expensive, 625 RGB leds would be rather pricy

#3, Yak:

SD card would be a little harder, because the SPI port on the AVR is already rather busy with controlling the LEDs. Could use a second AVR to do this though, and communicate between the two via I2C or serial. I haven’t worked out the timing requirements, but it seems doable.

or…

we have to find a way to push the video without a computer. embed the file on (sd) card with a video microcontroler?

I second tjhow’s comment above, this needs rgb leds.

OOOH NICE!!

Now all we need to do is get a rgb peggy working with this ;)
