The much lower signal level from those kind of transducers makes it  necessary to reduce the distance between the transducers in order to still receive a reasonable signal amplitude. So I took my <a href="https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/" >previous lasercut design</a> and reduced it in size so that the distance between the transducers is only 120mm. I went to the <a href="http://zurich.fablab.ch/" target="_blank" rel="noreferrer">local FabLab</a> and and lasered two copies of the downsized design.</p>https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/Wed, 06 Apr 2016 00:00:00 +0000https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/<figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="auto" alt="20160228_Projekte_133" width="1024" height="683" src="https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/images/20160228_Projekte_133-1024x683_hu_6e691f43e05a1d76.jpg" srcset="https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/images/20160228_Projekte_133-1024x683_hu_6e691f43e05a1d76.jpg 800w, https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/images/20160228_Projekte_133-1024x683.jpg 1280w" sizes="(min-width: 768px) 50vw, 65vw" data-zoom-src="https://soldernerd.com/posts/ultrasonic-anemometer-part-17-lasercut-mechanical-design/images/20160228_Projekte_133-1024x683.jpg"></figure> <p>In my last two posts I have gone through my new anemometer circuit both in <a href="https://soldernerd.com/posts/ultrasonic-anemometer-part-15-a-new-attempt/" >theory</a> and <a href="https://soldernerd.com/posts/ultrasonic-anemometer-part-16-testing-the-new-driver-circuit/" >practice</a>.

The guys at dangerousprototypes.com picked it up (<a href="http://dangerousprototypes.com/2014/12/16/arduino-based-inductance-meter/" target="_blank" rel="noreferrer">http://dangerousprototypes.com/2014/12/16/arduino-based-inductance-meter/</a>) and this blog got more visitors than I could ever have imagined. Thanks, dangerousprototypes.</p>
