Building these DIY kits happens on your own risk. We can't do support or give a guarantee for correct function, because that depends on your own skills. Be responsible and check the building instructions before you buy. Thank you!
The new Erica Synths & Moritz Klein - mki x es.EDU line
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.
In total, we have developed 9 kits to build a fully-featured modular monosynth: a sequencer, a VCO, a wavefolder, a noise/S&H module, a mixer, a VCF, an
Envelope generator, a dual VCA, and an output stereo mixer with a headphone amplifier.
Additionally, an affordable eurorack case with a DIY PSU will also be available. While these kits are easy to build, we did not compromise on design and
functionality. We will launch one kit every 4-6 weeks. For each kit, there is an extensive user manual (40+ pages; can be downloaded separately) that will dive deep into not only the
electronics behind each circuit but also the fundamental principles of sound synthesis. We hope that the mki x es.EDU project will inspire future engineers and will contribute to the
ever-growing diversity of electronic music technology.
Erica - EDU VCO
This is an easy to build VCO with a really extensive documentation and explanation of the circuit. Excellent learning kit!
The mki x es.EDU VCO is the first educational DIY kit in this series. It is an analog sawtooth-core oscillator with a reasonably accurate volt/octave tracking, made from just a handful of basic components. It features sawtooth and pulse outputs as well as 1V/oct, FM, and PWM inputs.
Here is the VCO introduction video on Youtube and here's a build video by Synth DIY Guy.
Power 7mA @+12V, 7mA @-12V
Width 10HP
Depth 25mm
This is a Do-It-Yourself kit, not an assembled module. Building instructions can be found here.
DIY level: Easy/Medium. Very good introduction to DIY!

Erica - EDU Envelope
This is an easy to build Envelope Generator with a really extensive documentation and explanation of the circuit. Excellent learning kit!
Many iconic sounds like the squelchy acid bass line, snappy techno kick drum, and swelling dream pop pad wouldn’t be possible if it weren’t for envelope generators. So, the next module in the mki x es.edu line is a slightly optimized ADSR envelope generator. Optimized because it has only 3 controls. With sustain on, it outputs an ASR (attack/sustain/release) envelope, but when the sustain is set to a minimum, it becomes an AD (attack/decay) envelope generator that ignores gate length; Release and Decay are controlled by the same knob. A looping function and an inverted output make the module more versatile for complex patches. The full EDU DIY system is designed to have 2 EG modules, therefore everyone aiming to build the whole system will need 2 kits.
Here is the EG introduction video on Youtube and here's a build video by Synth DIY Guy.

Erica - EDU VCA
This is an easy to build VCA with a really extensive documentation and explanation of the circuit. Excellent learning kit!
mki x es.EDU VCA is a simple yet efficient dual VCA for your eurorack system. It has DC-coupled inputs so you can use the VCA both for audio and CV signals. Inputs of the second VCA are normalled to the first one which allows to split the audio signal to both VCA or control both VCAs with a single CV. A 60-page build manual explains the electronics behind the module and provides step-by-step build instructions.
Here is the VCA introduction video on Youtube and here's a build video by Synth DIY Guy.
