Reader for letter recipients with little or no eyesight

Official letters, invoices and advertising mail are of course also sent to people who do not (any longer) see well enough to be able to read them. There are commercial solutions in the trade, but they cost a few thousand euros. That’s why we set to work and the result is a reader who lights up printed matter, photographs it with the camera of a single-board computer, interprets the content, and reads it out in proper style with a computer voice. The best: self-built for less than 250€.
