I have modified the GUI to include new speed range which is more in keeping with the speed a Ferris Wheel should go. Essentially the main speed scale is from 0.1-0.2. Due to the weight issues you have to run the Ferris Wheel at 0.3 speed to pick up enough momentum to get it to turn at all.
I have also cut down the bulky code from the Raspberry Express so that it is less hefty.

I will update this blog over the next few days with more detail.
Enjoy!
