It’s been a while since I posted the last update on the anemometer project. The reason for this is that I’m struggling with the aerodynamical design. By the way: Click here for an overview over the ultrasonic anemometer project: /projects/arduino-ultrasonic-anemometer/

A classic afternoon project. I was in need of a variable voltage and didn’t have a proper lab power supply available. But I did have a solid 12 volts from an old computer PSU. So I built myself this little thing.
