I recently created Moo-Bot, a robot cow scarecrow jumping over the moon, for a local scarecrow competition.
My inspiration was from my 3 year old son singing "hey diddle diddle, the cat and the fiddle..."
The project was a lot of fun to work on with my son, and I blogged about it in full detail here:
It wasn't too difficult of a project, and would love to share it with others for inspiration on their own projects this Fall.
