After watching his video on how he designed this very compact driver board for driving IN-12 nixie&rsquo;s, with some very cheap parts like the CH32V003 microcontroller I was determined to make a version for the IN-16 nixie tubes I bought.</p> <h2 id="different-nixie-types-driving-design-choices">Different Nixie types driving design choices</h2> <div class="image-grid"> <figure class="align-center "> <img loading="lazy" src="https://www.swissnixie.com/tubes/IN16/IN16_5.jpg#center" alt="IN-16 Nixie" height="400px"/> <figcaption> <p>IN-16 Nixie</p> </figcaption> </figure> <figure class="align-center "> <img loading="lazy" src="https://www.swissnixie.com/tubes/IN12B/IN12B_3.jpg#center" alt="IN-12 Nixie" height="400px"/> <figcaption> <p>IN-12 Nixie</p> </figcaption> </figure> </div> <p>I managed to snatch up 6 beatiful IN-16 Nixies on Ebay, these are quite a different style then the IN-12 tubes cnlohr used in his project.</p>
