BTW, Ellied, could you help me identify this part? It looks a bit like a through-hole mount resistor, package is of similar size and shape (perhaps a bit longer), but just a plain, medium grey cylinder. On that cylinder it says 1R00 / FRJ / 8437E / W80S in light grey text. I can't seem to find this on Google, though
<bofh>
egg: misread that as "thulium Falcon"
<APlayer>
It seems to have a constant resistance of 2 Ohm or so in either direction, but I only looked at it with a multimeter, so it's hard to tell if it's a resistor or something else
<whitequark>
APlayer: that seems like... a resistor
<APlayer>
Could be a small inductor, or something I don't know about, though
<kmath>
<stephentyrone> @bofh453 The hits keep coming. Try this one out: ⏎ 1. Compute SVD to get condition number. ⏎ 2. Use condition number to… https://t.co/egBcbk2Fpw
<whitequark>
pretty sure it's a resistor
<whitequark>
not sure why it measures 2 ohms though
<whitequark>
shitty meter?
<APlayer>
Pretty long leads
<APlayer>
Long and thin
<whitequark>
nah
<APlayer>
Definitely has an impact, I've noticed this before
<whitequark>
those are in tens of milliohms at worst
<whitequark>
go look up conductivity of copper or tin or whatever these leads are made of and compute how large the resistance is.
<APlayer>
Nope, way more. Had to approach zero ohm for a thing, and was pleasantly surprised that the remaining few ohms disappeared if I removed the leads and took a shorter connector
<whitequark>
and how do you know that's not contact resistance?
<APlayer>
The 2 ohms now?
<whitequark>
no, "the remaining few ohms" above
<whitequark>
because that's definitely not lead resistance
<APlayer>
Might be from the connections inside the leads
<whitequark>
inside??
<whitequark>
!u −
<Qboid>
U+2212 MINUS SIGN (−)
<APlayer>
Those are normal plugs with long wires and separately attached probes. The wire->probe plug might have a resistance
<whitequark>
!u -
<Qboid>
U+002D HYPHEN-MINUS (-)
<APlayer>
Well, not inside, but suggest a better word :P
<whitequark>
let's say you have copper leads that are 0.3 mm in diameter and 50 mm long
<whitequark>
an order of magnitude smaller than my inital guess, even
<whitequark>
and three orders of magnitude smaller than "remaining few ohms"
<APlayer>
It's about 1m of wire, I think. But alright, not 2 ohms, point taken
<whitequark>
ah, you meant meter leads, not component leads
<whitequark>
those are longer but also thicker, and they're more thicker than longer

Anyway, the multimeter is a good one. It was used at a military grade production site but was decommissioned as "broken". No idea why it was labelled this way, but the readings it provides are good.

<APlayer>
Good night egg! :-)
egg is now known as egg|z|egg
<egg|z|egg>
meow
<APlayer>
whitequark: I doubt it's contact resistance too, I stripped a layer of oxides from the component leads (you can even see it in the image), and I moved the leads this way and that. Goes up to 5 Ohms (rarely) and occasionally down to 1.6 or so Ohms. But no less than that.
<whitequark>
that sounds exactly like contact resistance plus some other thing
<whitequark>
e.g. contact resistance and your meter being crap
<APlayer>
The 5 ohm part, yes
<APlayer>
But it stabilizes at 1.6 + a few 100 mOhm
<APlayer>
And, as I said, the meter cannot be crap
<APlayer>
With semi-good contact, I can short the probes and get 0.6 Ohm
<whitequark>
it literally was decommissioned as broken
<whitequark>
of course it can be crap
<whitequark>
also
<whitequark>
"With semi-good contact, I can short the probes and get 0.6 Ohm" plus "Goes up to 5 Ohms (rarely) and occasionally down to 1.6 or so Ohms"
<whitequark>
combine to "this is a 1.00 ohm resistor, exactly as it says on the tin"
<APlayer>
So that's the meaning of 1R00?
<whitequark>
of course
<whitequark>
that's the standard marking
<whitequark>
R stands for decimal point
<APlayer>
TBH, the standard marking I know would be black-brown-black-golden
<whitequark>
not all resistors are color-coded
<whitequark>
none of the SMD ones are
<whitequark>
also, it's not golden
<whitequark>
if it says 1R00 then it's at least 1%
<APlayer>
I'm not even talking about SMD. The markings on those remain black magic, to me
<whitequark>
the EIA 1% markings are a simple mapping
<whitequark>
the rest is mantissa plus exponent
<APlayer>
Humm, I see
<APlayer>
Well, at least /that/ is clear now
<APlayer>
Thanks, and sorry for being thick, haha

I'm legit super glad that SMD resistors aren't color coded

color coding is cute but it still strikes me as a great way to make sure folks with any kind of color blindness have a rough time of things
