Giant Raspberry Pi Thermometer Shows Temperatures Around the World

What’s the temperature right now where you live? What about in Moscow, Cape Town, Mexico City, or Athens (either one)? Rather than scroll through your phone or furiously type into a computer, you could instead use this Digital RPi LED Thermometer by Anders Severinsen.

Severinsen's device looks roughly like a classic glass thermometer in shape — though wooden and much larger — and is meant as a household wall decoration. It displays the temperature numerically on its round base via a 1.5 inch OLED display, while a visual representation is shown via a ladder of WS2812B LED lights that extend up the body. In use, the "thermometer" cycles through a list of cities of your choosing, or the location on display can also be manually selected using buttons on the side.

The project is powered by a Raspberry Pi Zero W computer, which pulls data from OpenWeatherMap.org. If you want to build your own, code is available on GitHub, along with vector files for cutting the enclosure. Much of the electronics are placed on a custom PCB, and Severinsen has a limited supply of these available if you'd like to purchase one. You can follow his work on Instagram and Twitter, so either of those may be a good way to get in contact!
