The Dark Arts of clock repair open before me. I feel the need to wear flannel. …to create a basement workshop. …and to live where it snows most of the year. What brought this malady on? A clock.
Today’s post is a How-To for a project I recently completed: a temperature-only Weather Underground Personal Weather Station made from an ESP8266, a MAX31820 temperature sensor, and a few miscellaneous parts. The whole project fits inside a 3D printed project box for mounting on an exterior wall that is sheltered from the weather.
The open source project files are in my MAX31820WeatherStation Github repository.
After obsessing like a Lotus Eater for a week, I’ve finished my newly-invented (I hope) 25 Lotus Flowers puzzle!
The open source 3D Printer files are on Thingiverse; I’ve also written a How To sheet, with instructions and challenges. I modestly ;-) hope it’s as mathematically interesting as the famous 15 Puzzle… we’ll see!
In my previous post, I replaced the electronics of my several-year-old lunar clock design with modern parts. In this post, I’ve replaced the laser cut parts with 3D printed parts, with particular attention to the clip that holds the photo interrupter in place.
In my previous post, I designed a 3D printed sensor junction box for my well tank depth sensing project. In this post I solder… a lot.
In my previous post, I finished the Web Service that the ESP8266 uses to upload well tank temperatures (and eventually a depth estimate) to a cloud database. In this post, I turn to the mechanical design of the case for the RJ45 jacks for the 1-wire interface.
In my previous post, the ESP8266 Arduino Sketch was reading 12 temperature sensors. In this post, I describe the progress on the web side of things: the PHP web service that stores temperatures in an SQL database.
In my previous post I started the electronics and software for an Arduino Sketch for an ESP8266 WiFi microprocessor and several MAX31820 temperature sensors, that will eventually estimate and upload the level of water in our well water tank.
I’ve begun another Arduino/ESP8266 project: reporting the level of water in our well tank. This project will involve the ESP8266, MAX31820 temperature sensors, some mechanical work, sending data to a web-based database, and interpreting the temperature data to estimate the well water level.
I have to confess that sometimes I need a push to make the right design choice.
It’s been a long time – way too long – since I worked on my Lunar Clock project. In the meantime, Sparkfun has introduced new, inexpensive microcontrollers aimed at Internet-of-Things applications. I knew one of those new microcontrollers would be perfect for the Lunar Clock, but I dragged my feet.
