Last year I picked up an electronics kit for building a miniature weather station. I finally built a prototype of it tonight on a breadboard. It’s fully functional and I believe I can consider the codebase release v1.0.
OLED display showing current date and time. 
OLED display showing current weather. 
OLED display showing 3-day weather forecast. 
ESP8266-12E module. 
l. to r., DHT11 temperature and humidity sensor, BMP180 pressure sensor, and BH1750FVI light sensor.
The next step will be to design a custom PCB for this, which I’ve never done before. Should be an interesting challenge.
