LEGO version of a split-flap display to show three digit number (second proof of concept)

In this version, I have added a touch sensor to detect the 'zero' position. To go to a next number, the wheel is rotated 36 degrees for each next count. The position is reset every time the lever touches the sensor, this prevents drift.
The second proof of concept still contains only a large one and two, all the other numbers are not yet ready (not enough bricks ;-)). I have added small numbers on the flaps, so you can see that it works.
At the end of the video, you see a rendered image of how the final flaps will look like. The reason that I have chosen black/red as colors, this is because they are most affordable. For 3 digits, I have to make 30 flaps. That results in a total of 750 flat tiles (3068) PLUS 750 flat tiles inverted (11203). So every cent counts.
I don't like the large gap between the two flap-parts, thinking of minimizing that. But have no idea yet how to ... suggestions?

Nice! Can't wait to see the big numbers finished, ;-)

Lego has been ordered to build the flaps and the wheels. As soon as I have this up-and-running, I will release a new video.
