To help poor countries I was working on Arduino Nano (3$ computer) with a 2" OLED monochrome display (very very little energy required, especially if you show pixels only 1/10th of a time and use eye remanence). I don't have time to make it through, but maybe someone will be interested. It has low CPU but you can stream any kind of data through USB serial.
