Moritz Klein

Moritz Klein makes videos that aim to make DIY electronics more accessible. He focuses on synthesisers and has worked with the synth maker Erica Synths on a range of educational DIY kits.

Each video designs an analogue circuit from scratch, such as an oscillator, a drum sound, a delay or a compressor. He starts with a simple idea, builds it on a breadboard, listens to the result and improves it step by step. The explanations are calm and thorough, with clear diagrams and real measurements. Videos are long, but they suit viewers who like to follow every step.

Some highlights include:

He designs an analogue kick drum circuit from scratch, explaining how each part shapes the sound.

The first part of a series on building a voltage controlled oscillator, the circuit at the heart of an analogue synth.

A step by step design of an audio compressor, a circuit that evens out loud and quiet sounds.

The channel has around 170,000 subscribers.

Moritz Klein is an excellent way into electronic engineering, especially for anyone who loves music. Designing circuits from scratch teaches the fundamentals of components, signals and feedback. It connects to careers in electronic design, audio engineering and acoustics, and the skills apply far beyond music. His videos also show the real process of design, including the mistakes and fixes along the way.
