@NickAlexeev That has been a very well known trick to trace manufactories in the south of the Netherlands for a few years now.

They leak/dump their byproducts from making MDMA and such into the sewer. Big group of correlated locations was rolled up that way a year or two ago.

The cause to the solution is also why in some areas of the western world it may once again be bad to drink the tap water. Since outflow and treatment paths aren't geared for drug manufacturing byproducts, leaving them in the water, which then trickles into the ground water that is eventually used for tap water again.

Folks, how much do CAN bus controllers vary these days? What's the most sophisticated CAN controller on the market these days? To be considered, it could be built into a MCU, as well as an external peripheral.

@NickAlexeev I usually stick to the Atmel range of products for ease, so I'm biased, but I'm also quite happy with their CAN-enabled MCUs for Automotive use.

I don't know who voted to close electronics.stackexchange.com/questions/174334/… as "unclear what you're asking", but I see nothing that is unclear in that question...

Is the second graph a common one? Can't say I've ever seen it before.

@jippie no, it's not a common curve. Vce isn't usually fixed, and since a BJT is a current-controlled current source, it usually makes more sense to plot Ice

oh... misread, not talking about datasheet curves

@W5VO I wonder if I fell for the same trap.

lot of gibberish on the stack today (not referring to the question above btw)

@jippie I can see how that transfer curve is relevant, but it's not the one I'd chose for a common-collector amp

Why can I only vote to migrate to Superuser or EE.META when voting to close? The photon question needs physics or some such.

@Asmyldof because we usually don't have enough volume to justify such a link

migrations are... messy... if they aren't done right. Some people have a tendency to want to push **** around instead of putting it in the trash

@W5VO What do you mean? Wouldn't it make sense to be able to vote/advise a move to any relevant site in the stack network?

Hm

Buy better moderators? :-P

@Asmyldof You're welcome to take the job

you get what you paid for ;)

@W5VO Nah, I'm too expensive :-P

There's a reopen vote of an editted question and I just can't get myself to read it

It's so messy on my eyes with all the red and green and ugh

@Asmyldof You can select the "Question (revised)" tab, and it'll show you how the question looks on the site

@Asmyldof I meant that I'm not getting paid for it

@W5VO Ah, okay. And: I know.

Turned out to be an easy decision

@W5VO Just as a point of interest, does a moderator need "us" to vote for moving, though? I have seen stuff get moved to Arduino and other SE's regularly enough, but I can't vote for that, forcing me to vote to kill a potentially useful question that was just put in the wrong place, but also definitely does NOT belong on Superuser.

So, I'm happy to kill-vote or otherwise if it gets the attention and then gets moved to the right place, but it feels "piss-off-y" to vote to move it to SU when it clearly doesn't belong there.

@Asmyldof Flag it for migration

if it is a good question in the wrong place, then flag for migration. If it's just a bad question, close it

hm, wondeirng if this is any good ... ebay.de/itm/131531345045

@W5VO Noted.

@PlasmaHH Good is a relative term.

In this occasion at least

I cant find any stability measurements about this particular one... probably some oem formfactor of another more common model...

how old is it? those things have a finite lifetime

@W5VO finite lifetime in hours... its always hard to tell, no runtime provided in that auction... they can be good for many years if someone stored them in their basement back in 95

A friend of mine bought a rubidium std from ebay.com/usr/rf-buy2008 a year ago, and it still works.

@steverino it all depends on the time this thing was running and is running... if it has 20 hours left and he ran it for 2 since then...

I am not well versed on the subject to add much. I merely thought it was worthwhile to add another EBAY seller to look at for comparison.

Know what? I'm going to make dinner! YES!

Hope that helped

@steverino its not so much about the buyer but about the device... that particular one I found today isnt known very much at all anywhere...

on a totally unrelated note, today for the first time in my life, I destroyed a mosfet by bleeding

Can't remember for sure, but I think I haven't yet

There's a lot of grey fog around the first years between age 4 and 8

So I might have

@PlasmaHH That's a new one for me

@W5VO I would not recommend it. Unless you are an emo, there are more satisfying ways to blow them up

@PlasmaHH I've used multiple methods

but never by bleeding

usually the bleeding is a consequence, not the cause

hehe

its probably the same effect as spilling some drops of a drink on your pcb or something like that

of course I'm a bit paranoid when turning on my power mosfets

control circuitry goes "whats up?" and mosfet is like "yay, linear, yay, 10 amps"

Usually mine go something like... "Hey control circuit, remember how I used to have voltage isolation between gate and drain?"

So I'm a fan of galvanic isolation

once bitten twice shy

once in the lab? or after a sunny day with a thunderstorm in the park?

Hopefully durable enough to last a full day; since the purpose is for costuming effects for cosplay involved folk.
