I find the rose windows of Gothic cathedrals awe-inspiring. From the rigid formalism of Chartres to the flamboyant explosion of Tours, their marriage of geometry, philosophy, and aesthetics with stone and glass is awesome. Built at a time when science and spirit weren’t as divided as today, each window is a statement of the beauty, order, and harmony in the world. Using only a pair of compasses (dividers) and a straight-edge (an unmarked ruler), the Gothic architects created myriad lace-like designs, making stone hang in the air and glass sing.
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.
After obsessing like a Lotus Eater for a week, I’ve finished my newly-invented (I hope) 25 Lotus Leaves 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 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.
