Thank you for the pics and explanations! Seeing such big power transformer in a wooden box terrifies me, probably more than it should.
For the ADC, I’m not too sure what you could use. The easy way would be to use ZMPT101B, and live with the fact that you would be using 1% of its range (you would need to check its resolution). Maybe you could also try to rectify it using an ideal diode IC.
The fact that a capacitor is marked with a 1000V label does not necessarily mean that 1000V are present on its terminal (but you should use caution). I don’t think the voltage makes it out of the realm of electronics.
It’s quite hard to answer your question, as the board is quite dirty and you provided a single picture. You could check for continuity and capacitance value with a multimeter
Turns out that this is common in Japan for tea fields. They mount big fans on poles all accross the field for it (you provably have to zoom in to see them)
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?
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
For edits whithin a page, I use inkscape. Both program combined have covered all my needs until now.
I have one of these right in front of me (SPEC-3). They sure look very nice, but mine would need some work to properly work again :( Time’s not kind on electronics
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.
I don’t know so much about EGS, but probably some of the following (most of which I don’t use very often, I hope I recall correctly)
Freecad is getting more and more attention. When version 1.0 releases (soon), it will be something worth checking out, but there is still work to do.
It depends on the use cases. I don’t like how this post makes it look like the “Linux” alternatives are drop in, one-to-one replacement. Inkscape has been immensely useful to me, but for professional work, it might not be a reasonable replacement.
What do you mean exactly by organic maps editing tools? I was using organic maps before to add businesses, but now StreetComplete can also do that (and more!). I sometimes use Vespucci because it is very powerful, but it’s a bit of a pain to use.
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.
Je passe souvent par cette gare, et je n’avais jamais remarqué qu’il y avait autant de trains différents. Stylé.
Dans le même domaine, cette carte live du trafic ferroviaire suisse est intéressante.
Ça m’est arrivé il y a longtemps sous overwatch (fedora, proton), mais je n’ai jamais trouvé de solution. Je me doute que ça puisse avoir quelque chose avec avec le fait de changer d’application avec Alt+Tab. Éventuellement tu peux vérifier que proton est bien à jour ou changer de compositeur (KDE, GNOME,… )
Pour quel budget? A ~200.- le Sony WH-1000xm4 est un bon casque haut de gamme, mais ça fait un petit moment que je ne me suis pas informé. Le nouveau xm5 me semble trop cher.
J’avais fini par acheter un Senheiser Momentum 3 mais il est généralement bien plus (trop?) cher.
I believe it does. Weakly reciprocal license like LGPL is not equivalent as a permissive license like Apache. I see two main things on the top of my head:
On top of this, it really should not be complicated to license this code properly (unless rockchip wants to allow point 1, which is illegal)
