I love that blue display, reminds me of my Passat I used to have. Blue seems to a great colour for digital displays.

It's nice, but is it using a full digit for just the decimal point?

...it followed me home?

LOL. Well, if something's going to follow you home, that's a nice one to do so.

At least it's got plenty of digits to spare. :-DMM

Surprisingly it is only a 8.5 digit meter though.

Yep, all the others are there for other purposes.

Adopted a cat from my local shelter.

We have 3, all rescues.  And, as they say, the only reason we have 3 is that my wife would turn us all out if I brought another one in.  At least, that's what she says...

Blue is weird. In many ways it’s actually a terrible color for displays, especially pure (monochromatic) blue, like most blue LEDs, since that’s the lowest-contrast primary color, as our eyes are the least sensitive to it. That’s why blue LED displays are so annoying. But VFD blue is not monochromatic, it’s usually closer to teal, so it contains a lot of green and a bit of red, too. So it can be excellent.

That's strange I always that that blue was the colour that human eyes are sensitive to and hence why emergency vehicles tend to have blue lights on them?

Human eyes are most sensitive to green and it is the last colour you lose in an accident such as a chemical into the eyes. I was told that is why emergency showers / eye wash stations on industrial sites have green lights above them.

Green is the color we're most sensitive to, I've read. If you want to read a ton of research on the relative merits of different color LED displays I highly recommend going to PubMed and plugging in terms like "blue LED" and you'll find a bunch of stuff. What I found to be the most interesting is that some colors are apparently good for your health, while others are demonstrably not. What you said, tooki, has the ring of truth to it to me. (bright) blue LEDs literally hurt my eyes, while VFD light, and also green ones, totally different. Its relaxing. Also, the green ones seem to last longer. I have a night light that has a bunch of green LEDs in it thats been running pretty much continuously for years and it doesn't appear to have gotten any dimmer at all. Which is pretty amazing.

The blue colour of emergency vehicle lighting is somehow related to the little fuss our countries had nearly 80 years ago...

In Germany, the blue light was introduced in 1933. In order to meet the requirements of air-raid protection (blackout), the police vehicles were then specified to be equipped with blue light, since blue light has the highest scatter in the atmosphere and was therefore not visible to bombers at high altitudes.
In the same year, the fire brigades were equipped with the blue light, too.
The introduction of the flashing light or the rotating beacon instead of a calm glowing light was only in the 1950s.

Much more important today: The blue colour is not used in any other traffic sign or lighting.
Therefor very easy and fast recognizable.

Thanks for the info.
Just FYI, I think you mean “traffic signals”, aka “traffic lights” (Ampeln), and those never use blue. Signs are the printed things (Strassenschilder), and those most certainly are routinely made in blue.

Sure. I apologize. My "dumb" fault.  :palm:  |O |O |O
I stand to be corrected. It is all about traffic lights and lighting in traffic, of course.
Every traffic sign regarding the destination of highways (Autobahnen) is blue with white lettering on it, for example. Some other "normal" traffic signs, too.

But I asume: That´s enough OT...

Anyone in Oz need a spare bench stool? With another 20% off $34.32 AUD delivered.

I would double check the quality of the chair. Pneumatic springs are known for blowing up someone's ass.
That would be a very bad and very likely "once for a life" anal penetration.

The lights here in Japan are green (well, to me anyway :) ), but they call it blue.

I'll point out a random green light or green thing to my (Japanese) wife and friends and they'll say it's midori (green), I point to the same colour green traffic light and they'll say aoi (blue). However, the Japanese word for blue also encompasses a lot of what we would call green too.
The use of midori as green as a separate colour instead as a shade of blue only really became common post WWII. Ancient Japanese had no distinction between blue and green at all.

I think the lights were bluer in times past, but they are definitely green now with the LED's being used these days, I guess the name just stuck.
Any circuit design must contain at least one part which is obsolete, two parts which are unobtainable, and three parts which are still under development.

I haven't seen the blue traffic lights in many years to be honest. There used to be a lot more of them. Since they swapped to LEDs I think they are all green (at least where I tend to be between Tokyo and Nagoya), but the older ones were definitely blue as can be seen in the picture I attached. I think there are also parts of China where blue is still used.

They are also still "sideways", as far as Europeans would be concerned.

It’s true, I’ve never been to Japan. (Sadly! I wish to change this.) But traffic light colors are determined by international accord, and it’s red/yellow/green. That it’s often a bluish green (as it was in many US traffic lights, too, until LED came along) doesn’t change that it’s still green.

Just as an aside, in USA you occasionally see the horizontal style, too!
