LED Crystal Crown

In this project, we’ll create a wearable LED Crystal Crown using a simple circuit made of 7x Super Bright White LEDs wired in parallel and powered by two coin cell batteries wired in series.  

Party Bag

The Marquee Party Bag is a purse embedded with several LED Matrices and a Lilypad Microcontroller. The LEDs are easily programmable for the user to convey marquee messages or to simply make beautiful patterns. In this tutorial we will go through the step by step process of making this project.  

Fellowship of the Things! – SparkFun’s Internet of Things Video Series

The Fellowship of the Things is SparkFun’s newest series where our team of Creative Engineers build connected ‘internet of things’ or IoT projects. IoT is a broad category that is becoming much more popular, it basically entails any kind of wireless connect device which could be used for home automation, healthcare, smart grids, as well as wearables to name a few categories.   In this episode, Sarah and Shawn tackle some home automation with an interesting twist on front door security.  

SparkFun Fellowship of the Things Apartment #5 – Smart Mirror

Sarah and Shawn build a smart mirror using the Intel® Edison, an LCD, and a little bit of elbow grease. The mirror displays real-time weather data from openweathermap.org, and the information shown can be changed simply by swiping a hand in front of the gesture sensor! Make your own by following the tutorial we created.  

Build a Connected Bear with SparkFun!

Happy IoTuesday! In this week’s edition, I build a connected stuffed bunny for my newborn niece (and yes, even though we refer to it as a bear for title purposes, we realize it has decidedly lagomorphic qualities).   Having recently moved to Colorado, I’ve been dealing with the challenges of living far away from family for the first time. This drove me to design a special method of communication for just my niece and myself—a stuffed animal that would alert me, all the way in Colorado, any time she played with it back in New York.  

Valentine’s Day Box of Talk-lates!

It’s Valentine’s Day, and we know you are ready to pull out all the stops to impress that special someone. Finding the perfectly sweet and personalized gift can be a challenge and outright anxiety inducing. Fret no more! This box of chocolates will send your Valentine sweet nothings via text message as they eat.  

Remote Smoke Machine

Check out our blog post on how to build this tiny, remote activated smoke machine made from an e-cigarette tank and a vacuum pump. Simply fill the tank with glycerin and you can make convincing smoke for cosplay, theater or pranking your coworkers!  

What is a Battery?

Batteries offer a fantastic way to store electrical potential energy in the form of chemical reactions. We take a brief look at the fascinating history behind the invention of the modern battery and explain how they work, complete with animated hand-drawn diagrams.  

What is Voltage?

Voltage is the electric potential difference between two points and is defined as the work done per unit charge to move a test charge between those two points. But how does all that relate to electricity? In this video, we’ll show how electric charges can build up on surfaces, known as “static electricity,” and how those charges can be used to define voltage. Obviously, a static electricity demonstration requires the creative use of balloons.  

What is Electric Current?

When electric charges move, that’s called current! In most circuits, this movement is accomplished by electrons in a conductor. As it turns out, an electron doesn’t need to move very far; it can force other electrons in the conductor to move. In the video, we demonstrate moving electric charges with a tube and some metal balls. We also examine conventional current vs. electron flow and how good ol’ Ben Franklin can be blamed for that bit of confusion.
