Recently, I've been working on a ten k egg for a while, and I recently just finished it way simpler than I would have otherwise. Here's how:
I turned on Pokemon Go, taped my phone to a motorized Lego technic crane boom and set it on rotate. I taped an Xbox controller to the back as a counterweight, and it helped the crane to stop resisting the rotations thanks to the weight of the phone. While it still takes a while for the rotations to add up to anything, it still works and is better than walking when you live in Ontario, when we still get twenty below days and a few inches of fresh powder in March.
If you're as lazy as me, tell me how you hatch eggs and put on kilometers without leaving the house?
