Did you know you can turn a 606-style kick into a voltage-controlled instrument with just one transistor? Instead of being locked to one pitch, it can now be sequenced, bent, and pushed into sharper, more aggressive tones.
My new Kick Drum Circuit Design Guide covers this and many more techniques for designing analog percussion circuits from scratch. Now available in the Erica Synths web shop.

KONSTRUKT-8 is here!
The Erica Synths & MKI DIY Modular Drum Machine is in stock at Thonk and shipping NOW.

I wrote a book that teaches you how to design an analog kick drum circuit from scratch.
Starting from a simple oscillator, you gradually build up the full circuit – adding variable decay, pitch modulation, distortion, and CV control along the way.
Each chapter includes a breadboard layout and a QR-linked simulator, so you can actually try every step yourself.

Here’s how you turn a pile of components into a modular drum machine – one circuit at a time.
KONSTRUKT-8 is both a hands-on electronics course and an analog instrument you build from scratch.

This VCF design is stripped down to the bare essentials: just two diodes and a capacitor.
The diodes act as voltage-controlled resistors by biasing them with the CV and adding a scaled-down version of the audio signal. Together with the capacitor, the circuit behaves like an RC low-pass filter - but with a cutoff that follows the CV.
If you want to build and tweak this yourself, our DIY VCF kit is available now in the Erica Synths shop (link in bio). . . .

Did you know you can build a classic distortion effect using just a resistor and two diodes? It creates a soft-clipping stage that chops off the top and bottom of a waveform – adding warmth, crunch, and a more aggressive tone.
This is a very common building block in analog audio, and the foundation of countless distortion pedals.
Our new Output Mixer Learning Kit teaches you how to take this idea further by applying this distortion circuit to a 4-channel mix, adding a distortion amount control, and even routing individual channels to external effects.
You can grab it now in the Erica Synths web shop. . . . #synthdiy #diysynth #electricalengineering
Did you know you can build a complete analog synth voice from just three simple circuits? A schmitt trigger inverter-based VCO to generate the tone, a crude transistor VCA to shape its volume, and a simple diode/capacitor envelope to add dynamics. No microcontroller, no DSP - just a handful of basic components.
You can try this yourself with Labor Assembled, our ready to use circuit prototyping station. Link in my bio.

Did you know you can build a drum sequencer with just a shift register, a diode, a button, and one resistor? By routing the chip’s last output back into its input, it can record rhythms and play them back. No microcontroller, no code necessary.
It’s the foundation for our DIY Drum Sequencer kit, which takes the idea further with step deletion, dynamic accents, and even melodic patterns.
Check out the full breakdown on YouTube – or grab the kit and build the circuit yourself. . . .
