Big news, the Adafruit Learning System just added its 900th guide!  Two new great holiday guides pushed the total over the top this week: Festive Feather Holiday Lights and Starduino: 8-bit Super Mario Tree Topper

Even more impressive than the number of guides is that the learning system is only 3 years old so it’s averaging almost a new guide every day since its creation!  If you’re curious the very first guide in the learning system was this TTL serial camera guide from July 2012 that was moved over from Ladyada’s original homepage ladyada.net.  With over 900 guides the Adafruit Learning System is the place to learn about Arduino, Raspberry Pi, electronics, wearables, 3D printing, and much, much more.

The Festive Feather Holiday Lights project shows you how to build fun holiday lights that are powered by Adafruit’s Feather boards:

Spice up your holiday decorations using Adafruit’s Feather boards to add interactivity in a tiny package.  Feathers are little Arduino-compatible microcontrollers that give you all the functionality of a full-size Arduino in a much smaller and battery-friendly package.

You can put a Feather into almost any project, like these festive holiday lights that animate and change color at your command.  The 32u4 Feather combined with a color and proximity sensor lets you change the color of holiday lights by holding up a brightly colored object to them.  TheBluefruit LE Feather lets you change the color of lights using a smartphone or tablet and the Bluefruit LE app.  Your holiday decorations will be full of joy with Adafruit’s Feathers!

Top your holiday tree with the Starduino 3D printed video game tree topper project too:

Let’s build an 8-bit tree topper! This project uses the GEMMA to run a NeoPixel ring stuffed inside a 3D printed Mario star. You start out by printing four star model parts. Then, you’ll build and program the circuit. Next comes assembly, and finally you’ll power it up and place it atop your tree! (Thanks to Artie Beavis / AtmelMakes for the name!)
