Chicken coop auto-door opener so I don't have to get up at 4AM in the summer. It was just a basic Arduino system but I learned that large canning jars make excellent enclosures: waterproof, reusable, easily modified and replacable lid.
I might use that on my kids...
Not advisable to jar your kids
I did something similar, but gave up chasing parasitic electrical losses and didn't want to make the solar panel to power it huge.
Nice! Would you please share your code?
