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 wick the 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: https://www.phoenixcontact.com/en-us/products/printed-circuit-board-terminal-sptaf-1-7-35-il-1861988
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.
Actually, a least some cars (probably more than you think)/have some sort of “emergency” breaking signal, which often result in the usual breaking signal blinking for a while. You need to seriously slam the brakes to see it though. E.g: https://m.youtube.com/watch?v=j_osu1WgGMU
There is also a nice technology connection video talking about braking lights for electric cars and in general, which can be dangerous.
It was always under my nose, but I never realised it was there. Thanks for the tip!
The gnome news in this channel are likely sourced from planet gnome. They also provide RSS links :)
We are working towards having a product properly packaged. This is a prototype that is not mature enough yet to justify the cost/time to package it. Moreover, this custom chip is used to measure ultra low currents (down to femto amps), so any packaging could potentially interfere with the measurement capabilities (-> no epoxy). It is however protected by a large shielding box, but it’s no use during assembly/modifications :/
I feel very out of the loop here. Can someone please explain what is going on? There’s always been some mockery online about some of Gnome’s stance (minimalism, app indicator) which is annoying, but does not seem too bad. But full blown targetted harassment? Why on earth would someone target them specifically?
