DIY Builders & Educators
These creators make synth DIY approachable. Whether you're soldering your first kit or designing your own circuits, their videos are a great place to learn.
Moritz Klein
A German YouTuber who explains synth circuit design from a beginner's perspective, skipping most of the maths in favour of intuitive, hands-on explanations. His VCO, VCF and VCA series became the Erica Synths EDU DIY modules. Start here if you want to understand how circuits work.
Molten Music Technology / Molten Modular
Robin Vincent's channel documents his journey into Eurorack, including a Modular DIY series for complete beginners covering tools, power supplies and building your first case. He also designed the Molten Motion Meter with Befaco.
Look Mum No Computer
Sam Battle builds wild DIY synths and created the Kosmo format – a larger, beginner-friendly DIY module format with free stripboard layouts.
HAGIWO
A Japanese designer sharing low-cost, often Arduino-based Eurorack modules with full schematics.
Lantertronics – Aaron Lanterman
University lectures on analog circuits and synthesizer electronics – perfect if you want the theory behind the circuits.
Channel 37
Designer of the bus boards we sell, with videos on DIY Eurorack building.
Synth DIY Guy
Tutorials and reviews for the synth DIY enthusiast – build guides, kit reviews and practical tips.
Kristian Blåsol
A Swedish YouTuber whose DIY Modular in a Week series builds a complete modular system from scratch: case, power, cables, bus boards and modules, with clear explanations of each step. His power cable video is also on our power cables page.
Music Thing Modular – Tom Whitwell
Designer of famous open-source DIY modules such as the Turing Machine (a random looping sequencer) and the Workshop System, a small complete modular built at workshops around the world. All designs are open source, so they are great for learning how real modules are made.
Kit makers by difficulty
Where to find kits that match your skills. "Full kit" means every part is included; "PCB + panel" means you order the components yourself from the BOM.
| Level | Maker / source | What they offer | Notes |
|---|---|---|---|
| Beginner | Erica Synths EDU DIY | Full kits | Through-hole; based on Moritz Klein's videos, so you learn how each circuit works |
| Beginner | Befaco DIY | Full kits, some with SMD parts pre-soldered | Many also exist in VCV Rack: try first, solder later |
| Intermediate | Music Thing Modular | Full kits via resellers; open-source files | Turing Machine and expanders; Workshop System at workshops |
| Intermediate | DIY shops such as Thonk | Kits from many small designers | Each kit lists its difficulty; read the build guide before buying |
| Advanced | Mutable Instruments (open source) | Files only: PCB, BOM, firmware | Fine-pitch SMD and firmware flashing; see BOM for a worked example |
| Advanced | Westlicht PER|FORMER | Files and iBOM | A large SMD sequencer with an STM32 and display |
Workshops and events in the Netherlands and nearby
Building together is the fastest way to learn. Keep an eye on these places:
- WORM, Rotterdam: hosts the yearly Dutch Modularfest (live sets, workshops, a DIY area and a makers' market) and build workshops, such as the Music Thing Modular Workshop System build led by Tom Whitwell in March 2026. worm.org
- Volt Music Store, Rotterdam: synth workshops and demos in its showroom from time to time.
- Superbooth, Berlin: the big yearly modular fair every May, with a DIY area. In the same week, the Berlin Modular Society's DIY Kit Day offers a day of soldering kits together.
- Your local hackerspace or makerspace: many have soldering evenings where you can bring your kit and get help.
