Paperback: An Open-Source, Low-Power Digital Picture Frame
In an increasingly connected world, it is desirable to have devices that embrace the convenience of the Internet while still holding onto the familiarity of the traditional. Paperback is an open source, low-power digital picture frame built using an ESP32-series microcontroller and a 6-inch, 7-color ePaper display. Leveraging these two technologies gives Paperback several special capabilities. First, it can display 7-color, 0.2-megapixel images using no standby power; only when changing the image is power required. Second, it is nearly indistinguishable from a real photograph at distance—it requires no backlighting and displays smooth, unaliased edges. Finally, it supports wireless connectivity using Bluetooth Low Energy or Wi-Fi (802.11b/g/n), allowing for easy configuration from any laptop, computer, or Android smartphone. The open-source software supports many image formats and dithering algorithms, giving the user maximum control over how their picture is displayed.
