Finn and Jake's robotic best bro can now make your day mathematical, thanks toNoé & Pedro at [Adafruit Industries](http://Created by Noé & Pedro http://learn.adafruit.com/users/pixil3d), the awesome engineering studio featured in the third episode of our Make It Wearable series. It's been weeks since the friendly little game system has made an appearence on Cartoon Network's Adventure Time, so it's ample time for somebody to teach you how to make a BMO of your very own.
The tutorial requires the 3D-printed arms, legs and body, an 8x8 LED matrix, a Gemma circuit board that can be powered by Arduino, a battery, and a bit of wire. Solder it all together following the instructions in the tutorial, apply a little bit of acrylic detail, and—MATH! Your very own, LED-animated BMO.
