From where is this available? In the metal TO-3 package?

I see Alibaba have some for $0.10, but probably NOT genuine National Semiconductor parts

here's "The real Copy McCoy"

when chinese supplier mention the term 'Original' it's mean mostly a copy from the original design from their chip manufacturing,
and 99% not an original or surplus part directly from the National Semiconductor.

I really miss National Semiconductor. I cut my designer teeth reading their data and application handbooks - and using their devices of course.

@ Jack - When you get these ridiculously long addresses, the address actually ends just before the question mark.

Someone in the Cape caught this beautiful Puff Adder.

What makes them especially dangerous is that they bite first and reconsider later.  They have large venom sacs, large fangs, and strike very hard to drive the fangs deep.  Most likely the fastest striking snake because you don't see it bite.  They camouflage very well in the veld and is often the reason someone step on or near enough to get a surprise.  They do hiss if they become aware of you as a warning.

Apparently Puff Adders are more dangerous when they are small, because they have not yet developed the ability to control the amount of venom they inject, while a large one like this can.  Big or small, you don't want to get bitten by one.  The amount of venom is always too much.  Never hold them behind the head, they have the habit to suddenly rip their head out of your grip and strike before you realize what happened.

Hi guys, do any of you use AR glasses ?  For work ?
The new ones have some nice abilities judging by the tube's video's.

And something you can ponder on how electricity actually works.
It's a bit long winded though.

EVERYTHING We know about the Universe is Wrong, NASA physicist just exposed it all

Everything is a THEORY, like religion (theology = theory).
Nobody knows for sure.

According to some video's you can have like 3 displays to work on without using desk space.  The glasses detect your head movement when looking left or right and so bring the different screens into view.  The screens are scalable to a large size 150" ? and apparently the resolution is good on the micro O-led screens.

Something entertaining

How big is a lion ?

The females are a lot smaller, but they are the aggressive ones, especially if there are cubs.
The big males are a lot like us, noisy and full of show and threads, but will usually retreat.

There was a video sent around a while back where a farmer went into his tame lions camp.  When he saw the lions approach, he made the mistake to turn and run for the gate.  The ease with which the lion male grabbed him and dragged him away into the grass is unbelievable, like a cat that caught a bird.  The farmer's sudden turn and run triggered the lion's instinct to catch the now prey.  He survived with a few nasty holes. 

And why do wiemen always scream ?  Makes everything just more exciting.  For the lions.  And don't run.

And not too long ago it was common belief that we had lions roaming the streets.
Yes we do, but we put them away when we get visitors     Slowly, no running away .

Lions are the only big cat in Africa that will hunt people.
