Blinkenschild

Blinkenschild is actually a portable sign consisting of 960 RGB LEDs. The images/movies to be displayed are stored in a SD card in a Teensy3 board and controlled via bluetooth. Resolution is not as high as LCD monitors but the refresh rate is much higher:

This is done in realtime and pixelvalues are recalculated before display.

This is still too fast so i had to add 30 ms delay between the frames or we would not perceive it as a fluid animation but rather just blinking bright light.
