Yesterday I took a class at 3rd Ward called Solar Engines.
By the end, I had a prototype that uses sunlight to power two little motors.
When set on a flat surface, the motors make this delightful clicky, rattling sound.
I set it in my bedroom window to use as an alarm clock – it will make a cute noise on spectacularly sunny mornings.
Today was too dreary so he remained asleep. ;)
