Welcome to CircuitMess Synthia build guide!

By following this build guide, you'll learn how to assemble your digital musical sampler. With Synthia, you'll learn how microcomputers and other electronic components are used for sound production; you will be able to create unique music by playing with the pre-loaded sounds samples or recording your own sound samples with the built-in microphone, and much more.

Age group

Like it says on the box, Synthia is designed for anyone who's at least 11 years old.

You should approach some of the assembly steps carefully, so make sure to have an adult jump in if you need some help with soldering or tightening the bolts later in the process. It's okay to ask for help.

Don't worry, though! We'll go through the assembly step by step and provide some useful tips along the way. We'll give you a heads-up if there's something important to keep in mind while assembling.

Assembly time

It should take you approximately 2 hours to fully assemble your Synthia.

Of course, the assembly time depends on your previous knowledge and experience. If you don't have any experience yet, don't worry! It just might take you a little longer to get into the groove and overcome the challenges in the beginning.


You don't need to have any specific skills before getting your hands dirty with this DIY project.

The main objective here is to have fun and learn something new.

So hold on tight, read all the instructions, and get ready to have fun! This is a great opportunity and your first step in your big engineering career.
