Want to install a cool little digital weather display in your house but don't want to spend much money? Over on Adafruit, they show you how to build one using a few cheap components.
The display shows you the current weather, today's highs, and tomorrow's weather. The most expensive part of this project is the $US25 OLED display, but you can probably skimp out on that and find something cheaper if you want. Otherwise, it's just a couple breakouts and a few wires. Sure, you can easily just use your phone, computer, or practically anything else, but this is a fun little project nonetheless.
