You don’t have to be an avid bookworm to find use for an e-book reader. Take your local wedding band for example: with a big repertoire of songs to cover, you don’t really want to drag huge folders full of chords and lyrics around, tediously browsing through them to find the correct one for every new song. Even the biggest tree corpse enthusiast cannot deny the comfort of an e-book reader here. And since turning the page boils down to simply changing the content on a display, you don’t necessarily need to use your hands for that either. With that in mind, [mosivers] built a WiFi foot switch for his musician brother’s Kindle to flip backwards and forwards through the pages.
After jailbreaking the Kindle and installing busybox, [mosivers] set up a web server to serve two CGI scripts that write the previously recorded input events for forward and backward flipping respectively to
/dev/input/event0, essentially simulating a touch screen press that way. The foot switch, as counterpart, houses a battery-powered ESP8266, acting as access point for the Kindle to connect to, and requesting those page flipping CGI scripts whenever one of its two buttons is pressed.
If you don’t like the idea of jailbreaking your device in order to change the pages without using your hands, you could of course consider combining a more mechanical solution with the foot switch concept. And in case you want to see more of [mosivers], have a look at his DIY talk box project we’ve covered earlier.
