BeanInator

Device that automatically weighs and dispenses the perfect ammount of coffee into your grinder every time.

Why Does this exist

I have always wanted to make something like this to save me time in the morning morning. Taking the 3 minutes to weigh out the beans manually is the largest waste of time I have ever taken part of. So in order to become the most efficient being on earth, and ascend to a higher plane of existance. I need to have something automatically weigh my coffee beans.
