In the Red Dwarf TV series, Talkie Toaster wants to know if you want toast, and if not toast, then maybe a muffin or waffle, and it will pester you incessantly until you smash it with a 14lb lump hammer and throw it in a waste disposal. Now [slider2732] has actually gone and made one of the infernal machines!
He’s hidden a PIR sensor in the toaster handle to tell an Arduino Pro Mini when someone is unfortunate enough to be passing by. The Arduino then reads sound files from an SD card reader and plays them through a 3 watt amplifier out to a speaker. For that he uses the TMRpcm library available on github.
[slider2732] cleverly mounted the speaker to the side of the toaster along with some appropriately shaped bits and pieces, and some LEDs to make it appear and work much like the circular panel that lights up on the real Talkie Toaster. We dare you to watch the video after the break, unless you really are looking for toast. As a consolation, the video also walks through making it.
