Agenda on Bits & pieces - Sven Wehrend

Hello folks, today I want to give you a tutorial on how to start with AI on your own local machine.

The oscillator(s) - what it is and how it is working behind the scenes… With exception to noise every synthesizer needs some swinging circuit - better known as an oscillator.

After this chapter you will know all the basics around the semiconductor component transistor (BJT as well as MOSFETs) and their effects… The transistor belongs an own chapter, thanks to its gamechanging influence to a complete new generation of electroni…

Could not share my screen on Zoom, Google Meet or Discord - and how to solve it If you are running Debian 12 (Bookworm) or a similar modern Linux distribution, you might have encountered a frustrating issue: you try to share your screen in a browser or a…

A GUI is a fantastic idea… But what should it be - SDL, wxWidgets, or Qt?

Introduction to efficient build tools for C++ projects We now reach a rite of passage by moving from a Make-based build process to a CMake-based workflow.

Introduction to the topics data structures, algorithms and complexity / computability in C++ Caution - this tutorial is a theory-loaded one - we will discuss a bit of the basics about data structures, algorithms and complexity - all that especially in con…

Beyond the Single Note: Implementing Polyphony In our previous tutorials, our synthesizer was limited to one note at a time.

From Stateless to Stateful: Filters & Composition In previous parts, we built an oscillator.

Electronics 101–104 — Overview This page provides a short overview of the electronics introduction series.

This course introduces C++ programming through the development of a small audio / synthesizer application.

Introduction into C++ (Part 3) C++ OOP Mastery: The Power of Composition (Has-A) In software architecture, there are two primary ways to connect objects: Inheritance (Is-A) and Composition (Has-A).

Introduction into C++ (Part 2) In this next example / tutorial we will have a look at sound producing program (aka a synth), for which we utilize the SDL library (Simple direct media library).

A simple introduction into C++ Hello folks, this time I want to start with a series about programming with C++.

What is BusyBox and why is it needed?

Interrupts - The doorbell analogy Imagine a person sitting quietly at home, deeply focused on reading a book.

The two important pillars - Digital-Analog-Converter and Analog-Digital-Converter What we haven’t checked yet in our journey around (analog) electronics and digital electronics where the converter circuits from analog to digital and vice versa - for this…

Hello Folks, today we want to have a peek look into cascaded combinatorics with the example of priority encoder and decoders….

After this chapter you will know all the basics around linear components, integrated amplifiers and op-amps… Integrated NF amplifiers Today, much-needed electronic functions such as NF amplifiers are no longer predominantly constructed from “discrete” (fr…

After this chapter you will know all the basics around semiconductor components like diodes, transistors (BJT as well as MOSFETs) and their effects… A nonlinear component is a device whose current–voltage relationship is not proportional.

Storytelling and the order of things Hey reader, today I want to talk with you about the (right) order of things and its importance.

Hello folks, today I want to continue the series about simulation of synth modules with LTspice.

Hello folks, today I want to continue the series about simulation of synth modules with LTspice.

Hello folks, today I want to discuss with you the simple LFO made by David Haillant.

Hello folks, today I want to start with a topic that I had already longer in my mind and finally took hands on.

Hi there, a few months ago I decided, I would want to go to a form of webspace where I dont have to spend money.

Today, I want to show you how you can modify your Odoo frontend, I wont go to deep into owl and instead just show the basic steps for implementing modifications and changes via HTML5, CSS und javascript.

Here I wanted to document how to setup a python based backend (here: Odoo, but it could also be for example Django) on a pristine Debian / Ubuntu on After a new installation of Debian / Ubuntu you need to install a couple of packages to start of with a us…

Hi there, finally this week the nandland go board I ordered from the developer Russell Merrick a month ago arrived.

This is an updated blog post from the 08-05-2025, to ensure that you can enjoy to compile the latest version of Kicad and its dependencies.

Introduction Hi, today I want to share with you the basic knowledge of DIYing your own synthesizer modules - those do not need of the eurorack standard although in my case they are.

It is about time, to share another favorite of mine with you, and this is duckburg and the duck universe.

Today I want to show you, how to connect to the DE10-nano board, the successor of the DE0-nano board.

So, you decided you want to learn fpga programming and have done the prerequisite from the introduction 0 as well as done the simple logic circuit via quartus’s bdf files.

So, you decided you want to learn fpga programming and have done the prerequisite from the last blog post.

Today I want to start a blog post series about hardware programming.

Introduction Rare earth elements, often shrouded in mystery, play a crucial role in our modern world.

Introduction Rare earth elements have long been the backbone of high-tech magnets, with metals like neodymium and dysprosium playing pivotal roles in various industries.

OP-Amp Today I want to speak about op-amps.

In meinem mobilen Setup, dem NiftyVCase, habe ich meine DIY-Module gesammelt (mit Ausnahme des Doepfer A-124, den ich wegen seines großartigen Klangs einbauen musste).

Analog Computers Today I want to speak about analog computers.

Dieses Mal haben wir einen verschachtelten Patch, der ein neues Mitglied enthält, den Zufallssequenzer von rat-king, der, wie der Name schon sagt, schöne zufällige Sequenzen liefert.

So here is another small patch idea for the Doepfer A-100 system, this time featuring the SEM filter from Oberheim, incarnated in the Doepfer modul A-106-5.

After this chapter you will know all the basics around time-sensitive components like coils and capacitors and simple circuits utilizing those components… Electronics 102 Time-sensitive components After reviewing and extensively describing the most import…

Hier ist also eine weitere einfache Patch-Idee für das Doepfer A-100-System, diesmal mit dem SEM-Filter von Oberheim, verkörpert im Doepfer Modul A-106-5.

Hier ist also eine weitere Patch-Idee für das Doepfer A-100-System.

When you fire up your browser to visit a website, you most probably did not noticed a very important mechanism underlying the browser and working in the background.

This is a small, incomplete list of topics I’d like to write about in the mid- to far future.

Also kaufte ich mir einen günstigen Eurorack-Koffer von Doepfer und ein Set Frontplatten plus Netzteil für den Pocket Operator Modular 400 von Oddvolt, um die besagte Maschine in ein Eurorack-Modulsystem einzubauen.
