Allie Katz does it again with another cool one Raspberry Pi-powered by “Adventure Time” which we thought was way too awesome not to share. Using our favorite SBC, the Raspberry Pi 5Katz recreated Marceline’s low ax from the beloved cartoon series that not only looks cool, it also plays itself! This isn’t Katz’s first foray into the land of Ooo: we’ve covered this cool topic too BMO OctoImpression project that brings the character to life with a functional touch.

According to Katz, the idea was to create a really cool low ax that would accompany a Marceline cosplay. However, there was one big glaring problem: Katz doesn’t know how to play bass. Sure, it’s easy to look the part, but who wouldn’t expect to have fun at the sight of such a cool ax bass? This is where the idea for this standalone bass guitar was born.

This project was put together with a variety of creation tools ranging from electronic to 3D printing to make the best ax bass we’ve ever seen. It’s important to note that when we say the bass plays on its own, it doesn’t exactly use the strings or neck, but rather has a built-in speaker to play songs from the series and a compartment hidden secret with a touch screen interface. We wonder if Katz could use the new Raspberry Pi 2 touch panel in a future version?

In the demo video showcasing the build, Katz gives an in-depth look at the building process. Many components have been 3D printed using Polymaker brand CosPLA and a Prusa MK4. Of course, the project also involved a painful amount of sanding to achieve the professional finish we see in the final product. The buttons are mounted along the neck of the guitar and are used to select which songs are played on a Raspberry Pi 5. A series of batteries makes the unit completely mobile, perfect for taking to conventions and completing the illusion.

You don’t need a fancy operating system to do this project, the Raspberry Pi operating system works great for playing music. Katz also confirmed that you can use Spotify to play more than just an “Adventure Time” playlist, effectively turning the low ax into a portable boombox.
