1 – Introduction

Marta Musik Maschine is a DIY, RFID enabled, multi-purpose, audio and light device for kids. It’s open source and you can build one yourself. It’s not hard at all, I promise.

Welcome to my blog about Marta Musik Maschine!

On the next few posts I’ll try to explain why and how I built a toy for children of around two years and up. This blog is dedicated to the idea of you, the reader, understanding my design considerations, allowing you to build your own M3 and if you like advance the casing, electronics or software part of this project.

Before diving into the build process and all its details, have a look at the finished product in action.

1.1 – Blog Meta Information

I’m not saying that I hate web development, media and publishing, but I don’t like it either.

In this series of blog posts, I’m going to present a multi purpose kids toy called Marta Musik Maschine. But before diving into the build process, let me say a few words about the blog itself.

This WordPress instance runs on a non-dedicated server (i.e. simple web space). I don’t see an easy way of hosting something like GitLab at the moment. All the source code, 3D models and KiCad files belonging to this project can instead be found in an external repository at github.com/martamusikmaschine/mmm.

I’m not a native English speaker. I’m writing the blog posts after long work days and evenings full of kids animation. Please forgive me the one or the other not too eloquent sentence (like this). If you find any misspellings or strange word constructs that you want to be fixed, just let me know by commenting under the article or emailing me (marta [at] martamusikmaschine [.] com).
