Summer 2021 Semester


Summer starts in April in Germany.

I’ve designed the curriculum for the University of Erlangen-Nuremberg’s first Audio Processing for the Internet of Things course and will be teaching via Zoom. Details here. The course is only open to FAU students, but I’m open to sharing my resources with colleagues and students interested in this field.

Hello Raspberry Boom!

Last week I finally received my Raspberry Boom I backed at kickstarter a few months ago. The Raspberry Boom is an infrasound measurement device for measuring inaudible low-frequencies in atmospheric and man-made events such as rocket launches, explosions, volcanic eruptions, storms, tornadoes, lightning, etc. The journal Physics Today just had an article on that topic.

I hooked up the boom circuit to a Raspberry Pi Zero W which is doing data collection and transmission to the global citizen science network for further analysis and data fusion, such as for earthquake detections. You can check out my station’s real-time data here.

At the moment the boom sits inside its housing on the window of my home office. I still need to find a permanent place to minimize the likelihood of it falling down and the influence of low-frequency wind turbulences.
