So, I had somewhat of a moment of realization...

Problem #1 - Cannibalizing a Clock for its LED Display
I got my clock which i had planned on using as a seven segment LED source. I took it apart, and as I suspected, it has a single integrated circuit running the whole display. To my surprise, any given input to the LEDs will light up two LEDs - not just a single segment of a number. I suppose since the tens-of-minutes digit only goes to 5 and the tens-of-hours digit only has to display 1 it's no big deal.

Problem #2 - Brightness
There is a plastic, tinted cover over the display, and a translucent, red film over the LEDs themselves, so when those are removed you have a very bright display...but i don't think it's bright enough still. I'll have a chance to find out this afternoon when i can take it out in sunlight. But I think the solution is going to have to be a custom seven-segment display in order to get the size of display I want (I would like bigger digits than the LCDs can offer).

Problem #3 - The double image. I just plain can't deal with this. It looked good at night, but it still bugged me...

And I was hoping to stay away from this, but it's looking more and more like an inevitability. Hopefully, I can just have a cantilevered piece of plexiglass in order to maximize visibility.

Anyway, parts are going to be getting in soon for the MPGuino, so I'm pretty excited.
