ESP8266 PlaneSpotter Color

After many hours of work I’m very happy to finally publish all the sources for the ESP8266 PlaneSpotter project. It is not yet really in a V1.0.0 state but I’m sure with the help of the community it will quickly get better. While this post is more a “making-of” you can find build instructions on Github: https://github.com/squix78/esp8266-plane-spotter-color   .....

Font Creator Now Creates Adafruit GFX Fonts

As first task for the upcoming Weather Station Color project I wanted to adapt my online font generator. Easily creating fonts in various sizes will make work on the Weather Station code a lot easier. Since my own display library doesn’t support the color TFT screen I switched to Adafruit’s library. They provide a converter but it needs to be compiled and I wanted to have this feature available on my web based font converter. So I analyzed the Adafruit font files and the converter.....

ESP8266 Weather Station on the “Big Screen”

The 0.96″ OLED displays I usually use for the WeatherStation are gorgeous but they could be bigger, right? Recently a bigger version of the SSD1306 based display became available on my favourite channels. Thanks to great work of the community (especially Fabrice Weinberg) the OLED library on Github  as been extended to supp.....

ESP8266: Turn a $9 Body Scale into a Smart Scale – Part 1

In this project I will show you how you can build yourself a fancy Withings-like body scale. I divided the article into two parts: Part 1 describes the hardware hack and Part 2 the software. In this project I used a cheap scale I bought in the local super market for 9 Swiss Francs (which is currently about USD $9.-) and I am optimistic that other digital scales will work for you as well. This project was a lot of fun since I had to do reverse-engineering, soldering, programming and (optiona.....

ESP8266 based Plane Spotter – How To

When I sit at my living room table I can see wonderful big airplanes in the final approach to Zurich (ZRH) airport or ascending to a far destination: Airbus A380 or Boeing B777 are ingenious proof of what we are capable to design and build. Quite often when I have visitors I start flightradar24 to get more information about the airplanes we see. But wouldn’t it be nice if this information would just be there, anytime I’m curious – without starting an app on my smart phone.....

ESP8266 Weather Station: Measuring Inside and Outside Temperature – Part 2

In Part 1 of this series you learned how to connect a DHT temperature/humidity sensor directly to your WeatherStation and to display the readings as an additional frame in the carousel rotation. In this second part I will show you how to setup a sensor node and post the readings to a free cloud service before fetching them on a WeatherStation (.....
