LEGO Mindstorms: The Tritimer {by R}

This is my Tritimer. It is a start/stop timer that counts minutes. As you can see it is built out of Lego Mindstorms.

I called it the 'Tritimer' because it has three sections in it that slow down the speed so that it will take exactly one minute to spin around a full circle.

I have used no programing in this build because we can't get the programing software on our computer. I have used the trial and error method with my mom as timer. If it didn't go correctly, I would just tweak the gears so that it would.
