Not too long ago, as I was eating a quick breakfast of toast and orange juice,
I was thinking about whether I should bring a coat with me to work. As I
crunched on my toast, I recalled the story of a student in the U.K. who had
designed and built a toaster that delivered a weather report to his toast. I
thought to myself, I have a toaster and I have an extra microcontroller in my
parts bin. Why not build my own interactive toaster?
In this chapter, I will show you how you can hack your toaster to toast one
of several different patterns onto a piece of bread. You’ll be able to display
messages and information on a small LCD delivered wirelessly to the toaster
from your home PC.
Robin Southgate has documented his Toasty project quite well at http://
news.bbc.co.uk/1/hi/sci/tech/1264205.stm. His project uses a Java controller
and a different mask material from what I use here.
