1 GHz Bandpass Filter with Distributed Elements

Introduction Working in a microwave engineering area I learned that classic components like capacitors or inductors are ditched away from the filter design and so called distributed elements are used. It means, basically,  that inductances, capacitors, LC circuits are created using conductive lines on PCB instead of soldering old school components. Pretty cool, I thought, let’s … Continue reading 1 GHz Bandpass Filter with Distributed Elements

Getting started with ATmega8u2 and other AVR USB microcontrollers

Introduction There is this USB specialized family or group of everyone’s favorite AVR microcontrollers. Apparently, you can use them as USB devices or hosts without any external components. Hell, you can even program them via USB port. All of that without any external component. One of those little guys I wanted to use  for my last project (reflow … Continue reading Getting started with ATmega8u2 and other AVR USB microcontrollers
