Designing a Lego orrery
I've always been a fan of the Lego Technic series, especially those models that have gears and cranks and moving parts. But it seems that Lego is shifting the focus of the Technic series away from functional models, so I had to take matters into my own hands. I think an orrery is the perfect project to build out of Lego Technic parts as it makes for a cool display set and is functional at the same time.
