  I do not know if they are open to the public per se, but it seemed to be something they do quite regularly. Concerning the material, they say on their site that it is a “polymer”. On this page they go quickly over how the measurements work.

  I was actually not visiting sensirion, but lumiphase. A smaller company they are investing in which does optical chips. It’s interesting stuff, they are also depositing unusual materials on the silicon wafer to make their chips work.

  Thanks! I recently was in the headquarters/production facilities of Sensiron which interestingly are located near Zurich in Switzerland. It’s quite rare to see production of IC’s in this country. The “magic sauce” of the sht40 and friends is the deposition of a certain matieral (can’t remember which one) on top of the classic silicon die.

  Hey! Props to you for trying something new. While the through hole components look OK, soldering large gauge wire can be quite tricky, especially if the soldering iron is not powerful. What soldering iron do you use? In these cases especially, it is important to wickthee wire first, wick the soldering pad and finally assemble the two. Raising the iron temperature for this can also be useful (I sometimes use 400° or a bit higher). It is counter intuitive, but hotter iron means quicker soldering job, and less heat in the surrounding area (e.g cable’s insulator)

  The green and orange colors are quite typical of the phoenix contacts brand. It’s not a perfect match, but this model is very close: phoenixcontact.com/…/printed-circuit-board-termin…

  Looks great!

  If your are looking for pur aesthetics, I would recommend trimming the resistors/leds, and bending their leads before putting them on.

  If you’d like some inspiration this guy has some of the best looking hand crafted electronics I’ve ever seen.
