It hasn't been quite a decade since the release of the Raspberry Pi platform, but it was definitely the hardware project that dominated the 2010s for us. For today's post I'd love the reminisce and review the big story.
This is the second part depicting the building of a keycode-based anti-theft system for a car.
In this Enginursday post, we talk about a fixing a problem the ESP32 Thing Plus had.
Using Sapien LLC's Arduino Shield and Electrode array we can expand our human senses.
I have finally gotten the hardware in (mostly) working order for my wacky fiber optic light suit. Let's check out what I've done!
Using cryptographic authentication, we created a super-secure remote control to open a garage!
Let's take a look at what makes 'main()' feel so cozy and welcoming - what has to happen to have variables initialized, objects constructed and stacks a-stackin?
Details from a project upgrading an old incandescent lamp to utilize addressable LEDs
Building a DIY personal, portable, briefcase computer workstation with a Raspberry Pi!
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.
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.
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.
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!
