[Martynas Mickevičius] has a grandma who is visually impaired. She enjoys listening to audiobooks as well as has been doing so utilizing a DVD player for rather some time. The issue is that there is no method for her to save her setting in between listening session. He set out to assist by building a devoted audiobook visitor that doesn’t have any type of buttons.
The job was influenced by a one-button visitor we featured back in November. like that project, [Martynas] selected to utilize the inexpensive, yet powerful Raspberry Pi. The primary difference is available in the manage method. He’s utilizing an NFC label reader, which is mounted in the top part of the RPi case. The picture above shows the rig during prototyping, however his final version is all bundled up in the pink enclosure as well as only needs the power as well as audio cable televisions linked to it. See for yourself in the demo after the jump.
Each book has its own NFC tag. When she’s done reading she can just cut the power as well as it will resume in the exact same location the next time it is plugged in. The label configuration is a large enhancement because it enables an entire library to be kept on the SD card as well as selected utilizing a different tag. With this hardware in location it ought to be trivial to code extensions to the system, like a script that utilizes text-to-speech to announce which book is being played before playback starts.
