EDU DIY FM Drum

Introducing an FM Drum circuit that fuses analog punch with metallic tones of FM synthesis. This DIY kit offers a wide range of sounds for your patches, from kicks to toms, metallic clangs and more – a great addition of versatile, rhythmic elements to your system!

EDU DIY Labor PSU Connector

PSU Connector for easily connecting your Eurorack modules to the Labor workspace!

EDU DIY Labor Scope

This DIY.EDU Labor add-on, featuring the oscilloscope, the voltmeter, the spectrometer and the tuner, turns the Labor into self-contained electronics development and experimentation station.

EDU DIY BBD

Before digital advancements simplified sound processing, engineers tackled delays using bulky tape echo machines or natural echoes from reflective surfaces. In the late 1960s, engineers Sangster and Teer innovated with the bucket brigade delay (BBD), a system that splits audio into samples passed through a transistor-capacitor chain. This method mimics how sound travels, delaying the output signal relative to the input. Over the course of building this module, we will reverse engineer the architecture of a classic bucket brigade delay, recreate a bare bones version on the breadboard – and then use a proper BBD chip to implement a simple audio delay effect.

EDU DIY Labor

Get started in circuit design with MKI x ES Labor. Developed in collaboration with Dr. Shalom D. Ruben, teaching professor of engineering at the University of Colorado, Labor is a fully-featured circuit design playground and a powerful electronics learning tool – all in one. Created as a universal platform for electronics education, Labor enables users to explore a wide range of topics, from fundamental concepts to advanced design techniques. Whether you're a beginner learning the basics or an experienced engineer refining your skills, Labor offers a versatile platform for experimentation and discovery. Build your own filters, oscillators, envelopes, sequencers – or anything else you can imagine. Or start with the fundamentals by following along with our series of educational DIY kits.

EDU DIY Snare Drum

No drum machine is really complete without a punchy, snappy Snare Drum. Together with the Kick, it creates the rhythmic backbone for most grooves. So for our percussion-focused second season of educational DIY kits, we knew we had to come up with a Snare circuit that would complement the Kick and Hi-Hat we’ve already released. After a lot of fine tuning, here’s what we came up with: introducing mki x es.edu DIY Snare Drum.

EDU DIY Hi-Hat

Synthesized, analog Hi-Hats are pretty fascinating. That’s because emulating any kind of cymbal using an analog circuit is tough since the sound a real cymbal produces is not quite pure noise, but also not really harmonic. Still, a couple of classic drum machines like the Roland TR-606 and TR-808 took their best shot at it, with quite strange-sounding results that have since become iconic in electronic music. Inspired by this, we decided to follow suit and continue our percussion-focused second season of educational DIY kits with the mki x es.edu DIY Hi-Hats.

EDU DIY Kick Drum

There’s nothing quite like the sound of old-school analog drum machines. Especially classic kicks like Roland’s 808 and 909 are ubiquitous in electronic music. Unfortunately, their circuitry is notoriously complex and difficult to understand. Enter the mki x es.edu DIY Kick Drum kit, which not only aims to shed some light on the fundamental circuit design principles behind those circuits – but also captures their unmistakable sound as a fully-fledged Eurorack module.

EDU DIY Compressor

Need some professional polish in your modular system? With this simple diode-based compressor, you can shape the dynamics of your sound, adding punch and consistency to your patches. Whether you’re looking to beef up your basslines, add sustain to your leads, or tame the peaks of your percussion, this circuit’s got you covered.

mki x es.EDU DIY System

We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.

EDU DIY Wavefolder

Even though wavefolding is more of a west coast synthesis concept, it’s a great addition to the otherwise very east coast mki x es.edu DIY system. Why? Because it can provide a ton of unusual timbres for your patches: from a slight dash of brightness to harsh metallic drones. That’s why we came up with this super simple BJT-based double wavefolder.

EDU DIY Output

The mki x es.edu Output Mixer is essentially a panning mixer – it takes two mono inputs with adjustable gain and pans them left or right to the stereo output, and an integrated amplifier boosts the signal for use for headphones.
