The reason for this is that I&rsquo;m struggling with the aerodynamical design.</p> <p>By the way: Click here for an overview over the ultrasonic anemometer project: <a href="https://soldernerd.com/projects/arduino-ultrasonic-anemometer/" >/projects/arduino-ultrasonic-anemometer/</a></p>https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/Mon, 10 Nov 2014 00:00:00 +0000https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/<figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="auto" alt="_MG_0929" width="1313" height="875" src="https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/images/mg_0929_hu_2905037d3e78b0a9.jpg" srcset="https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/images/mg_0929_hu_2905037d3e78b0a9.jpg 800w, https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/images/mg_0929_hu_af6aaade06ce915b.jpg 1280w" sizes="(min-width: 768px) 50vw, 65vw" data-zoom-src="https://soldernerd.com/posts/variable-voltage-power-supply-using-a-lm317/images/mg_0929.jpg"></figure> <p>A classic afternoon project. I was in need of a variable voltage and didn&rsquo;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.</p>
