Keep Tabs on the Weather with rpi_status

[Facelessloser] is interested in glanceable information. Glancable devices are things like your car’s dashboard, your wristwatch, or widgets on a smartphone lockscreen. The glanceable information distribution system in this case is rpi_status, [facelessloser’s] entry in the Enlightened Raspberry Pi Contest.

[Facelessloser] coupled a ring of eight WS2812 RGB LEDs with a small OLED screen managed by a the common ssd1306 controller. Since he was rolling his own board for this project, [faceless] some buttons and a BMP180 temperature sensor. Going with popular parts like this meant libraries like the Pimoroni unicorn hat library for the WS2812 were readily available.

A simple display like this can show just about anything – from status of a nightly software build, to traffic along your morning commute. [Facelessloser] is using it for weather data. His data source is Weather Underground’s API. Weather information is displayed on the OLED. The WS2812’s display the temperature. A single blue light means cold. The ring fills as the temperature warms up. After eight degrees of blue, the color changes to orange, followed by red.

Check out the video after the break for a short demo of the board.
