I needed a powerful output stage for my function generator project. There are many amplifier topologies to choose from. Each one has its own pitfalls: be it high distortion, voltage and current limitations,… Continue reading
While working on my function generator project, I needed some source of waveforms. It needs to be adjustable and deterministic. It would be great if it was also electronically-controlled, to allow sweeps and… Continue reading
This post describes a simple FTDI breakout board I designed. It allows you to program any AVR chip with an Arduino bootloader (or similar). When building any project with a microcontroller, a means… Continue reading
This post is all about the venerable single phase inverter. Thanks to the ever improving maximum frequencies of cheap IGBTs and voltage ratings of MOSFETs, inverters are getting more and more affordable, efficient… Continue reading
Anyone working on a mobile robot might want to equip it with some kind of sensor for detecting obstacles. Otherwise your robot will end up crashing into its own creator – thus breaking… Continue reading
PID Controllers have been around for decades. They’re an extremely simple invention, from a mathematical perspective. Yet still, you see people misuse them – the most common ‘sin’ that has to do with… Continue reading
Motivation behind the project I don’t have a frequency generator and found myself in a situation where one would come in handy. I would like to be able to perform spectral analysis of… Continue reading
