I’m a big fan of homemade yogurt. I love it mixed with fresh berries, or granola (you have not lived until you make your own granola!). I also love traveling the hallowed digital halls of Instructables.com, and recently ran across a great ible for making yogurt. Imagine my surprise when I read that one of the commenters built a Arduino Yogurt Cooker! For about $25 or so, he has a temperature controlled gallon sized yougurt maker. Here’s a guy after my own heart! Read it, I think you will enjoy it as much as I did!
