I mean, at least they're giving a lot of notice?
<APlayer>
Hi Ellied! I might need some advice, if you have the time. I soldered that circuit, but it's acting weird
<SnoopJeDi>
yea the 2020 has been plenty of notice, and the scipy stack got onboard pretty early, I just thought the LTS stuff came off kinda "okay we're saying there's no support buuuuut"
<SnoopJeDi>
it sounds like they intend that any community patches/etc. to the LTS branch will remain on the official repo and go into the official PyPI package :/
<APlayer>
To be exact, it drops the voltage after a delay, but only to 4.6 V. The N-Channel MOSFET and capacitor seem to be fine, but I measured weird stuff at the P-Channel MOSFET and suspect it might be broken (Although it's more likely I screwed something up)
<APlayer>
Vds when on is 5 V, Vds when off is 4.6 V and Rds when off is 16-something MOhm

On an unrelated note, I may have just deflected another attempt by a random person to make me a Christian. o_O
<Ellied>
APlayer: sounds like you got drain and source mixed up, and when it's off it's conducting through the intrinsic source-to-drain diode
<Ellied>
so you're seeing the voltage drop because of that diode's barrier potential, but it can't turn it off completely
<Ellied>
bofh: oh my god new CSB video
<Ellied>
I have to watch that but I'm in class now
<Ellied>
well, imminently.
<APlayer>
Humm, possible
<APlayer>
And how would I figure that out?
<Ellied>
try reversing the drain and source terminals and see if it works?
<APlayer>
Uh-oh... Spent literally a day soldering this thing
<Ellied>
welcome to electronics :I
<APlayer>
Well, looks like there is no way around that, so I'll try it on the weekend
<APlayer>
Thanks for the advice!
<Ellied>
probably should have mentioned this sooner, but uh, you don't have access to a solderless breadboard, do you?
<APlayer>
I do, but when I tried to use it the contacts were so bad they were a few kOhm to MOhm each
<APlayer>
I just dropped it and relied on falstad testing and you double checking my results to make sure it works before soldering it
<APlayer>
Reminds me, the guy who will print the case wanted me to bring him the parts tomorrow, got to get them out of the basement and store them safely for transportation
<APlayer>
Anyway, I am off for now. Be back soon!

"this was a good example of a political science presentation" says prof. (narrator: it was not, however, a good example of a presentation in general.)

Withstand Political Science [Level 6 Illusion] - You create an autonomous apparition which is visually identical to you, and will attend presentations for you. Starting at level 8, you can optionally direct the apparition to take notes in your native language (although they will be gibberish if actually inspected). The apparition cannot answer questions.
<SnoopJeDi>
does it come in "speaker's slides are in Beamer" flavor for accelerator conferences?
<APlayer>
Ellied: Good news - I've just had another look at the circuit. Looks like I only need to swap two connections, both directly attached to drain and source of the P-Channel MOSFET. And no layout changes aside from that at all, in fact it would even simplify the layout a bit, as opposed to my fears.
<Ellied>
nice!
<APlayer>
In that case, the change could be performed quickly, I guess I can try it out tomorrow in a spare hour or so
<APlayer>
Also, yeah, on second thought what I measured while off was really consistent with diode readings I had from when I was playing with the components trying to get a hang of how they work. I guess your theory it is, then
<APlayer>
And yes, one of the MOSFETs had a G-D-S pinout, while the other one was G-S-D, I was wondering about that earlier. And given that my method of figuring out the pinout was... questionable, that seems even more plausible to have happened
<APlayer>
Thanks a lot for the advice and help so far! I'll report back my findings when I get to try it! :-)

sounds good

It's okay as long as she does not teach anything IT related

We have a teacher who teaches HTML, CSS and JavaScript and has virtually no clue of any of it. The code quality is worse than what me and some of my classmates picked up in two or three years of self-teaching, mainly from SE sites and simila
<Ellied>
meanwhile, my coping mechanism: why are JFETs not indexed by cutoff voltage???
<APlayer>
I believe, related: Why are the prime specs of MOSFETs written in large bold letters at the top of datasheets things like Id and Vds or similar, but Vgs(th) is never among them?
<Ellied>
yeah, usually it just says "low threshold" if it's low

Ellied meant to say: I think JFET cutoff gate voltage just has such a high variance (e.g. 0.8 to 4.0 V for the MMBFJ202) that it's not a big advertised characteristic
<Ellied>
also, I don't understand why the datasheets are so utterly devoid of frequency characteristics
<Ellied>
the only thing this one has is noise vs frequency

I guess I'll have to characterize them myself :V

I still remember that presentation where the screen of the machine running my PP presentation happened to be between myself and the class, and angled at nearly 90 deg. I could fake looking into the class while I actually had occasional glances at the screen, and have not peeked at my notes a single time :D

I actually just have my slides full-screen on my laptop when presenting.

Iskierka: cats?
<APlayer>
I am not even officially allowed to use a mobile phone at school, not mentioning laptops. Well, "officially" means the teachers "look away" when they see a student using their phone during a break, but being caught using it during a lesson means you may receive it at the end of the day from a secretary
<Iskierka>
cats.
<Iskierka>
e_14159, that two-screen mode is extra-convenient as you can put notes attached to each slide. And with strategic laptop placement no-one will realise how much you're depending on it
<APlayer>
Also, we have teachers hunting students using their mobiles apparently for the sporting interest. It's rather fun to observe how they perfected their "phone detection senses" (quite literally so, it seems) over the years. Some manage to figure out a student is using his phone without even looking away from the blackboard
<APlayer>
The hunting mostly happens during lessons, though, so *usually* it is safe to look things up or something during a break
<e_14159>
Iskierka: Three years of debating club have left me able to present without notes :-)
<e_14159>
APlayer: Reminds me of my school time, when no teacher noticed that the strange sounds you got from a tape player was actually interference from pupils calling each other.

e_14159: May I ask what the number in your name means?

Quite recently, during a German class, towards the end of it we started to hear loud music from the class next doors. The teacher leaves with a grim look on her face, 5 seconds later you hear complete silence from the other class, then some shouting, and after about half a minute the teacher returns with a portable speaker under her arm
<APlayer>
I mean, I am in the highest possible level of school in Germany, and the class next doors was grade 10. The seemed like an excessively stupid way to get caught for students who should be both, smart and old enough to know better
<APlayer>
But well, we had a good laugh, including the teacher :D
