Does anyone have information on how to open and close a chicken coop door automatically, using a photo sensor or timer?
Also, I've wondered if any inventor or company has created a wind-up lazy susan that is designed to approximately track the sun?
Lastly, has anyone in a winter climate experimented with creating a mini-ice house, perhaps filled off an out building roof and allowed to freeze?
Thanks for any ideas or feedback-
