Which is worse?
Smoke Emitting Diode
Light Emitting Resistor
Poll ends at .
@ryanc "Light Emitting Resistor" so an incandescent lightbulb?
@syntaxxor @ryanc lightbulb was my logic & why I voted "smoke", but an exposed resistor glowing is probably a more potent fire hazard.
@ryanc Resistor Emitting Diode?
@ryanc pretty sure we used LERs to light our house back when i was a kid
@joe @ryanc was Thomas Edison as brilliant a showman in person as they say he was
@joe @ryanc Some people even cooked their food over LERs!
@ryanc time emitting capacitor
@ryanc @catsalad Magic smoke being let out is always bad.
@ryanc "Someone has to clean that up" - smoke is worse. *g*
@ryanc are they any worse than transistor that is doing both?
@ryanc I wasn't sure, then I remembered that X-rays are also light.

@MauroV1968 @ryanc

You mean *o*mitting.

@knodel Well, Ryan asked what's wrong... "omitting" would be right, not wrong 😉
@ryanc

@ryanc
I voted for the light emitting resistor, but after the fact realized that's just an incandescent light bulb -- and, as it turns out, the magic ingredient in Hewlett Packard's first product: a wave form synthesizer sold to Walt Disney Studios to be used in "Fantasia".

So I guess I voted wrong -- smoke emitting diodes are worse.

@ryanc

Bang emitting capacitor.

Oop, wrong way. 😉

@Arapalla
Its own housing rapidly emitting capacitor
@ryanc
@Arapalla @ryanc iron emitting inductor
@ryanc light emitting resistors smell worse, unless the diode is a selenium rectifier, which, I heard really smells horrid when it goes.

@FuturisticRobert

The usual solution to this problem is to enclose the light-emitting resistor in a glass envelope filled with either inert gas or vacuum.

LERs so enclosed will emit light for a surprisingly long time—hundreds of hours—before failing.

@ryanc

@argv_minus_one @ryanc

I was assuming both options were failure modes. A glass enclosed resistor is not a failure mode its an essential device for light switch raves.

@ryanc a light emitting resistor?! So an incandescent lightbulb?
@ryanc @catsalad Any diode can produce smoke if you try hard enough. (I have tried.) Resistors also like to make smoke but I never tried hard enough to get them to make light. It feels like a challenge.
@ryanc
Dont these two converge to being the same thing?
@ryanc Smoke emitting diode is quite certainly done for. Light emitting resistor might still work afterwards. So the former.
@torgeros @ryanc also, fumes are a health hazard
@renardboy exciting, this is the first time I am talking to an actual bus
@torgeros most of us aren't on social media, despite improvements in accessibility technology it remains difficult for us to operate computers. But it *is* possible, I am proof of that.
@ryanc Both are usually locked behind a barrier. The diode at least bothers to let you know something is wrong when it is hidden away.
@ryanc Isn't the light emitting resistor commonly known as a... filament?
@ryanc Don't all resistors emit light? It's just in small quantities and in IR (ie heat).
@ryanc
In both cases smoke and light are involved. However the first one is being active where the second one takes it passively.

@ryanc

Can we have an "All Of The Above" option please? :D

@ryanc I don't think people understand what 'worse' is? Who wants smoke instead of a standard light bulb?

@ryanc My favourite is the Light Emitting Diode emitting the wrong kind of light.

"That's a different colour. Oh."

@ryanc liquid emitting capacitor
@ryanc smell emitting diode
@ryanc this sounds ridiculous, and that is precisely why i voted 😃

@ryanc Explosively smoke emitting capacitor.

Followed by a rapid evacuation from the lab due to unexpected olfactory adventures.

For the skilled among us, accelerated by leveraging the impulse from the top of the cap.

@ryanc

Depends.
If it is a large, old Selenium diode, that is life-threatening hazmat smoke.

(Two of our Math/CS profs were working on an early computer several decades ago when the power-supply blew with their heads in proximity. They were treated and released, but the dangers of Selenium rectifiers was impressed upon them.)

(A few old AC/DC trolley power conversion stations have striped "Se" warning diamonds still.)

@ryanc

You can make some resistors emit light, and that's ok. Even their purpose.

But when smoke comes out, that's generally a bad day.

@ryanc every light bulb is a light emitting resistor, so don't worry about that.
Smoke emitting diode sounds bad. Only does that once... 😂
@ryanc light emitting resistors were quite common until some years ago, they were called light bulbs, in german glühbirnen, which is nice, because it translates to glow pears :)
@ryanc a diode emitting light while in reverse bias
