Inspired by the last FLL theme, I figured out it would be nice to have wind
turbines as part of the layout... even if they actually might not produce
energy.
At first I thought of having one (micro) motor on each of them, but that would
get a bit too expensive and cumbersome. Then I thought of using some thread
between a motor hidden below and the turbine itself, but that proved to be
tricky and fragile. The final solution includes a 35cm long and 3mm thick
knitting needle that transfers the rotation from the bottom, which again gives
the possibility to run more than one turbine with a single motor. Some fine
tuning is still needed to get them to run smoothly though, but it is already
much better than in the beginning.
