Why 7x7x7 you ask? I simply ran out of money to buy the extra 169 leds and 2 extra TLC's to upgrade to 8x8x8. Good reason, huh?
What about something like a 3D letter rotating inside the cube.
Well I thought that the building of a led cube was a challenge, but that was nothing compared to the tedious and time consuming task of coding in new or additonal light patterns. What is really needed is a PC based GUI pattern editor/generator that could allow one to click and point led lights on and off and build a script of patterns and then generate a hex code or possible even a C array(s) that could then be easily pasted into a sketch and recompiled. I really liked building, testing and debugging my cube project, but I don't have a clue how people can have the time and patience to manually create complex patterns just using the Arduino IDE?Lefty
