A summary how to implement the logarithmic and exponential function using operational amplifiers - and how to use this to build simple mixers when combining with a simple summation amplifier
Summary on how to use operational amplifiers to build simple function generators such as square wave function generators. This approach can be used to build simple laboratory function generators as well as low frequency oscillators used for various applications.
A summary on how to derive the capstan equation describing the friction of a rope on a bollard, winch or a capstan
This blog post is a little summary or introduction on how to calculate Eigenvalues and Eigenvectors using power iterations that tries to use a little less formal jargon to provide a short overview.
A short summary about Kalman filtering
Summary of the most basic OpAmp circuits that are usually built as well as their basic properties
A short summary about the basic properties of Maxwell equations, the resulting electromagnetic wave equations and commonly used gauges (Lorenz, Coulomb).
Short summary of various commonly used Gaussian integrals (1 dimensional) most of the time not shown in school textbooks.
A short summary about the different meaning and interpretation of impedance, ABCD, scattering and transfer parameters in simple (linear) two port networks.
Mini article about the measurement of capacitance with AVRs with a minimum of external components (in it's most extreme form none external components exploiting the gate capacitance of the micro-controllers input)
This blog post summarizes a method that can be used to develop software in the same way one would when using object oriented techniques with C++, Java or similar languages. It's based on the method used by the previously mentioned languages to implemented that stuff on bare metal.
Short summary about the k-means algorithm and it's usage
Short tutorial on how to use libjpeg for simple image I/O (to read and write JPEG files to/from disk or memory and represent them as simple in-memory bitmap for simple CV experiments)
A short introduction into neuronal networks and backpropagation
Real first mini steps when using Amazon webservices. Adding 2FA to your root user, creating an administrative user, enabling 2FA there and creating access keys for CLI tools.
This article explains how to use an AVR as I2C slave device (basically how to set registers for the TWI controller) and how to interface that to an RaspberryPi running FreeBSD
This post describes a simple derivation of the complex inpedance formulas well known from electronics.
Something most drivers don't want to hear - a basic pallpark calculation of the optimal maximum speed that offers the maximum car througput on streets.
How to use the GPIO pins on the AVR microcontrollers when using avr-gcc
How to get started with the STM32F401RE nucelo development board on FreeBSD with gcc and openocd
