It's a long time since I read the highway code, but yes - powerful
headlights are illegal to use in the UK. It is illegal even to use the
car's fog lights unless there is thick fog. Additional lights that are
sharp enough to cause annoyance, distractions, or temporary blinding to
other drivers are always illegal on public roads.

The rules are quite simple. If you distract other drivers, it is
dangerous. If it is dangerous, it is illegal.


I'm in the US and we are allowed to have fog lights, but they can not be
used in town (except during fog). But on the rural graveled back roads I
see them used all the time, and never heard of anyone getting pulled
over by cops for it.

For what I paid for these Silverstar bulbs, I could have bought a pair
of those fog lights, but these mini-vans dont have any place to attach
them. The bumpers are plastic.

fog lights are useless unless it is foggy

thanks, NT


Don't see why it would be that much different than crossover distortion;
it takes time for the output to pass thru the dead band as one device
stops conducting and the other device begins, negative feedback reduces
crossover distortion just fine at low frequency when the open loop gain
of the rest of the amp is high.

How are you driving the complementary emitter followers of a class AB/B
amp into saturation, anyway? Wouldn't the base drive voltages have to
swing above and below the rails?

If what you're saying is correct, why would class AB amps exist? AIUI It's because class B's glitches aren't fully solved by nfb.


NT


They're pretty much "fully solved" at very low frequency, but a pure
class B amp intrinsically has a shitton of THD even for relatively small
signals, and so as frequency increases and open-loop gain drops off from
the dominant pole compensation the ability of the NFB loop to compensate
starts going tits-up fairly quickly.

It's not that NFB has _no_ ability to correct for crossover distortion
intrinsically, or distortion caused by any other source internal to the
amplifier design, it can do all of that stuff, but it's entirely
dependent on the amp having sufficient gain-bandwidth available to do it
effectively for signals in the range of frequencies of interest

The large signal sine-wave output of a class B LM324 op amp with unity
gain looks lovely at 20 Hz, materially indistinguishable from any class
AB op amp to my eyes, but like garbage once you start getting into even
the low kHz range

nodding plenty here

Sounds a little like capacitor windup in a control loop.
For which I just like to make sure all the amps hit the rail at about
the same time. That might not apply in your case.

George H.

no, the channels rail at different times. When they un-rail the system is not forgiving of errors.

These bulbs just connect to the 12volt source.
There is a relay between the light switch, and of course
fuses. Normal is a max of 14 volts during engine running.

So my question is, do you see 14V on the bulbs? Wonder
if poor contacts / wire sizing etc, making a few-volt drop.

Grin, maybe some stick-ons on the glass. A few tasteful fig leaves
or something. That would let you 'see' the glass too.

Not in the dark! A dim shower overhead light might have good optics.


How about glow-in-the-dark tape? I've used that on some
door edges (it's not noticeable during the day, but a dark-adapted eye sees it clearly).

It would be amusing to hide some UV nightlights in innocuous places,
like behind a light switch plate, both so you can find the switch,
and to keep the phosphors on the opposite side of the room pumped up.

There have been articles lately about the new Apple Spaceship campus,

We had a grubby bathroom refurbed at the cabin. The bathroom is small

First time I peeded in the middle of the night, I whacked my head on
the glass. It is very dark up here at night.

https://www.dropbox.com/s/k35nbdquxrywse6/P2190701.JPG?raw=1

There is a light/vent thing in the shower, so I was thinking it would
be cool if the light were on dim all the time.

https://www.dropbox.com/s/po8e9iku1a2zxt0/P2190702.JPG?raw=1

So I need an LED spotlight that runs at low current; most do. Maybe
the one already there would.

So I need to put an impedance across the switch for this light. It
could be a resistor, a cap, or a series RC. But it has to be small to
jam inside the switch box, and it can't get very hot.

A resistor could conduct 10 mA and dissipate a watt, which might work.
Or I could use one of those high-voltage XY-type film caps. If the cap
ever shorted, it wouldn't be a big deal... the light would just go on.

ps- It's 10F up here in Sunny California.


How about just using an illuminated light switch? Your eyes are going
to be pretty well dark-adapted, after all.

The glass is basically invisible. A reflection will be deceptive.

How about edge lighting it with the tritium dots?

They aren't very bright, and the clear glass will TIR the light
without deflecting it out.


If the same switch runs the fan, you should have have enough of a load
to light the neon bulb with no problems, but I don't know about the LED
fixture.

Separate switches for fan and light, so I may be able to run the light
dim. Cap across the switch maybe.

You'll probably get into code violations.

Code?

As in a world of hurt if someone gets injured.

I can't see how putting a film cap across a switch in a junction box
is going to hurt anybody. Slamming into a big sheet of glass in the
dark might.

1) unlisted device

XY self-healing film cap, spec'd to go across the AC line.

2) current leakage path around a switch

That's the whole point!

Defeating the switch. Using it in a way it wasn't designed to work,
thus invalidating it's listing.

3) wet room

You don't have running water in your bathroom? This is an outhouse?

4) NEC doesn't cover a stubbed nose or toes.

5) Compulsive need to follow rules.

Where the NEC is concerned, sure. Fire and electrocution are nothing
to mess with.

They should. I don't see anyone being pulled over for not using turn

We don't have deer in SF. There are lots down the peninsula, and up in

If they are smart, they won't wake up the hobos before running the steam
cleaner down the sidewalk.


The news story claims "Over 100!" discarded IV needles found in the
areas they surveyed but you can easily click through all the "red"
streets in the map and see that the tally tops out at barely 50. And
there are big clumps of 7 or 10 needles in some locations.

Pay one or two bums a couple bucks to dump their spent needles in a
couple locations and hey presto you've got yourself a story.

And you have an army of well-paid attorneys, consultants, NGOs,
providers, and city staffers actually soaking up the funding.

We never go downtown. That's for bankers and tourists. Our
neighborhood is green, quiet, clean, and safe.

I've never seen a needle on Ohlone Way. You might get stuck picking
blackberries.



It's a histrionic "story" crafted to play well with histrionics of all
political persuasions, left or right few Americans can seem to resist a
good "OMG THINK OF THE CHILDREN!" tale.

Meanwhile I'd estimate statistics on the number of children who could be
confirmed to have caught the AIDS or any infectious disease from any
discarded IV needle in SF or any other large city for that matter is
likely pretty close to 0.

The HIV virus is fragile out on its own.

"the average risk of contracting HIV through sharing a needle one time with an HIV-positive drug user is 0.67 percent"

Feel like playing Russian roulette? Seems hospitals are worried a
bunch about HIV and similar diseases.

Almost like nurses and phlebotomists have to deliberately handle dozens
of dirty needles/sharps a day as part of their job duties

They are not, however breaking their skin with them. They actually
train in the importance of not letting that *ever* happen.
