work in progress esp8266 and st7789 (240x240 ips lcd) mini info display framework. the idea is to make cheap wifi-connected info displays to put on your desk or around the house as always-on dashboards. the st7789-based lcd is crisp and bright and can be found for less than $4 online, and the esp8266 module i'm using (a wemos d1 mini) can be found for just over $2. since the esp8266 doesn't have enough ram for a full framebuffer (240 * 240 * 2 bytes per pixel) and the arduino graphics libraries are lacking important features like anti-aliasing, the rendering is done server-side using node-canvas and streamed over http as a raw rgb565 bitmap directly to the lcd driver. right now there's a single widget implementation which displays the median air quality index for a geographical area using data from purpleair.com (shown above). it should be easy to add new widgets since all of the data loading, processing, and rendering is done in javascript with the powerful canvas api. in
