Bob Dylan may not have needed a weatherman to tell him when the wind blows, but the rest of us rely on weather forecasts. These, in turn, rely on data from weather stations, and [Vlad] decided that his old weather station was in need of an upgrade.
His station, which uploads live data to the Weather Underground, needed to be solar-powered, weather-proof and easy to install. He seems to have succeed admirably with this upgrade, which is built around an ATmega328 and the 433 MHz link from the old station. As part of the upgrade, he built a 3D-printed enclosure and installed all-new sensors on a home-made PCB that are more accurate than the old ones.
He looked into upgrading the wireless leg to WiFi, but found that the school’s WiFi had a login page that he couldn’t get around. So he re-used the old 433 MHz radio and connected the other end of the link to an old laptop on the wired network. Good enough, we say. Now how about a snazzy display to go along with it?
