Concept and Motivation

• This project is aimed at building a toaster that can toast a given image onto bread.

• The toaster toasts the images on flash memory into reality via a moving array of digitally controlled heating elements.

• The aim of this project is to make toast more fun. A piece of bread with an image toasted on it is much more interesting than just plain toast.
