I got tired of kits that taught me nothing.
So I built ones that actually do. Professional mixed-signal PCB kits — with the documentation you always wished existed.

Every bad kit has the same three problems.
I've bought them all. Here's what I do differently.
A bag of parts, no story
You get components, a blurry schematic, and zero explanation of why the circuit actually works.
Every component has a reason
Each kit ships with a full write-up: what every part does, why it's there, and what happens when you change values.
It works. You learn nothing.
The LED blinks. You move on. Three weeks later you still can't design a basic op-amp stage.
Build it, then understand it
The assembly is the start, not the end. The documentation walks you through the theory so the circuit makes sense in your head.
Pro gear is out of reach
Serious mixed-signal design lives in corporate labs or behind equipment you can't afford as a student or hobbyist.
Real circuits, real prices
I design professional-grade mixed-signal boards at prices that don't require a corporate expense account.
The Kits
Everything I design, I test myself. If it doesn't teach something, it doesn't ship.
Diskreter ADC-Bausatz
Build a real ADC from scratch. Understand every stage — sampling, conversion, output. No shortcuts.
Power Meter Board
Measure power, voltage, and current the way pros do. Designed around industrial measurement ICs.
Mein erstes uC-DIY-Kit
Your first microcontroller project done right. From bare metal to working firmware — step by step.
Before You Build vs. After You Understand
This is what happens when a kit actually comes with real documentation
Compare Before & After
I got tired of kits that shipped components with no explanation. So I quit buying them and started building ones that actually teach you something.
This Is What You're Building
Every kit comes with the full KiCad source files. Explore the schematic before you buy — zoom in, inspect every component, understand the design.

Why MSD is different
Professional-grade PCBs
Designed in KiCad using real industry practices. Not toy boards — actual mixed-signal layouts.
You get the source files
Every kit includes the KiCad project. Read it, modify it, learn from it. That's the whole point.
Documentation that explains the why
Not just 'connect this to that'. Every section covers what each component does and why it's chosen.
Direct line to the designer
Questions? Email me. I'm the one who designed it and I'm happy to help you understand it.
Free shipping, always
Every order ships free worldwide. No surprises at checkout.
