Time Twister 2

Time Twister 2 is, as its name suggests, my second clock creation. It is quite a lot bigger than my first Time Twister.

Each digit is made up of seven segments which are connected in a chain. The connections are made in such a way that a segment can be rotated 180 degrees before the next segment is affected.

By rotating the first segment a specific number of turns you can set the last segment in desired position. Then by rotating the first segment in the opposite direction a specific number of turns you can set the second last segment. By rotating alternately in one direction and the opposite direction, you can set all seven segments of a digit using only a single motor.


Movement: Two LEGO Mindstorms NXT Intelligent Bricks. Five Servo Motors.
