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-28-new-hardware-tested/Wed, 07 Sep 2016 00:00:00 +0000https://soldernerd.com/posts/ultrasonic-anemometer-part-28-new-hardware-tested/<figure><img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="auto" alt="20160907_standaloneanemometer_024" width="1024" height="683" src="https://soldernerd.com/posts/ultrasonic-anemometer-part-28-new-hardware-tested/images/20160907_StandaloneAnemometer_024-1024x683_hu_3837f8421fee8371.jpg" srcset="https://soldernerd.com/posts/ultrasonic-anemometer-part-28-new-hardware-tested/images/20160907_StandaloneAnemometer_024-1024x683_hu_3837f8421fee8371.jpg 800w, https://soldernerd.com/posts/ultrasonic-anemometer-part-28-new-hardware-tested/images/20160907_StandaloneAnemometer_024-1024x683.jpg 1280w" sizes="(min-width: 768px) 50vw, 65vw" data-zoom-src="https://soldernerd.com/posts/ultrasonic-anemometer-part-28-new-hardware-tested/images/20160907_StandaloneAnemometer_024-1024x683.jpg"></figure> <p>I <a href="https://soldernerd.com/posts/ultrasonic-anemometer-part-27-ready-to-take-pre-orders/" >last time</a> proudly presented the new RevB board and got a lot of feedback from people who want one, too. As mentioned I have all the components here to ship up to 10 kits but I was reluctant to send anything until I had the chance to do some hardware testing. Not much had changed since the last revision but I don&rsquo;t like taking chances on things like this.</p>
