Enginursday: Multiple I2C Ports on ESP32
I'm using six of the same sensor in my fiber optic suit, with only four hardware configurable addresses. I need to take advantage of my ESP32 to create multiple I2C buses.
Enginursday: Ten Years of Testbeds
We collected over two hundred retired testbeds and turned them into art! Join us as we highlight this project and tell some of the stories behind these dusty old circuit boards.
Enginursday: The best part of waking up...
Many of us at SparkFun consume coffee for breakfast, maybe lunch or dinner, but for some go-getters it's all three. Join me as I dig into the habits and trends of our breakroom coffee setup.
Enginursday: Playing with CRCs in Python
Take a look at Cyclic Redundancy Checks beyond just copy/pasting an implementation. The underlying mathematical principles are very interesting, and you can try it yourself in Python!
Enginursday: ESP32 Thing Plus Web Server
The trials of setting up a Web Server with Bootstrap, SPIFFS and ESPAsync.
Enginursday: Upgrading the Lightning Detector
The trail-ready lightning detector has been out in the wild getting some good use. As summer nears its end, it is a great time to take the project back to the drawing board and figure out what should be upgraded, what should be added and what can be removed – just in time for some fall outdoor adventures!
Enginursday: 3D Printed Housing Fixtures
This summer I went on a tear setting up connected devices in my house with one goal; simplifying the mundane tasks of owning a house. The whole project has got me automating as much as I can, but also non-connected solutions are springing up as well. In this Enginursday, I build a roof over my new connected outdoor outlet.
