CircuitMess Synthia is a fully-functional electronic music device you build on your own. It's a device that combines a synthesizer (creating sound), a drum machine (creating rhythms), a sequencer (creating patterns and songs), and a sampler (recording and audio manipulation). The kit is great for both beginners and experienced builders.

Build your own synthesizer
Synthia isn't just a music player; it's a DIY synthesizer that puts the power of sound creation in your hands. No experience needed – just a curiosity for music and tech.
All-in-one music creation
Synthia has preloaded sounds, a drum machine (kick, snare, clap, hi-hats), a sequencer to memorize your beats, and even a sampler with a built-in microphone to record your own sounds.

Learn the science of sound
Go beyond making music – understand how it works. Building Synthia teaches you about electronics, sound waves, digital audio, and signal processing. Plus, explore coding to customize your sounds.
Endless sonic possibilities
Experiment with high-pass and low-pass filters, reverb, and the unique 'Robofy' effect. Tweak preloaded sounds, create new ones, and record samples.

Assembling Synthia teaches you about electronics and music tech. You'll learn how to put together electronic components and you'll understand how they interact within a circuit. In addition, you'll explore sound waves and digital audio while learning how synthesizers generate and manipulate what you can hear through signal processing. When built, you can even code Synthia.
We recommend Synthia for ages 11 and up. It's a challenging but accessible introduction to electronics and music tech. Apart from teens, adults with a passion for DIY electronic projects and sound creation will find Synthia to be great for learning and having fun.
Synthia's the perfect way to dive into the world of DIY electronics and music creation – even if you're a complete beginner. The kit includes everything you need, and the instructions will guide you through each step.
Tools you need: a soldering iron (also, a soldering iron stand and a soldering sponge) and solder, cutter pliers, standard 2.0 mm cross screwdriver.
Building Synthia typically takes around an hour and a half. But that's just the first step! Once it's assembled, the real fun begins – exploring sound synthesis, creating music, and customizing your creation.
After building Synthia, you'll have a complete electronic music studio at your fingertips. Create unique sounds with the synthesizer, build rhythmic patterns with the drum machine, and arrange them into full songs using the sequencer. You can also record your own samples with the built-in microphone and integrate them into your creations.
