Right. Well, your brightness is going to be function of the number of displays so obviously doing things as fast as possible is key. It doesn't leave a lot of time between refreshes to do actual work. I've done 8 digits but it was way too dim. There are ICs designed for this though and they're usually less than a dollar.
Wow! That's a pretty nifty idea! It took me a minute to figure out what you did, but as soon as I looked at the schematic I understood.. Well, depending on the light cut out rate of the leds (dunno the proper term for it) You maybe able to add up to 4 without dimming them too much. It just blows my mind.. Sounds like I need to get to work on another ghetto arduino segment*
@xavier2010 Check out the link in the video description for a schematic. I probably should be using shift registers for speed but I'm just alternating back and forth quickly between each display.

I am just getting into this myself, and I noticed your only using 10 outputs from the arduino instead of 17, are you using a shift register?
