That's not a sensor..

.. this is a sensor...




We had the marketing director from Cmosis visiting us at work. They make CMOS sensor for all sorts off applications, and they make the 35mm sensor for Leica.

That beast above is in fact only a APS-C chip (!)

Re: That's not a sensor..

Interesting. I didn't expect a sensor to look quite like that.

What a shame we cannot change the sensors in our cameras in the way that we used to change film.

Re: That's not a sensor..

Yes, scary great beast.

The sensors I usually design with are about 1/4 that size...

Re: That's not a sensor..

I guess Ricoh, at least, offers a sensor-based camera line, a opposed to a camera-body-lens line-up?

it's an interesting time for camera design. Am I the only one who thinks large sensor formats are a dying breed?

Four Thirds is a nice place to be...I'm staying!

Re: That's not a sensor..

OP71 were the originals, provided endless fun for school kids. Or get yourself an OC71 and scratch the paint off. Remember?

Oh yes. I did that.. and I still have one solitary OC72 in a tin can from my youth. Aah, it was all so simple in those days.

Fast forward via FETs, OP-Amps, digital video, Assembler, VHDL and 0402 resistors.. and I am now the proud owner of a twin triode valve, just to play with :-)

Re: That's not a sensor..

From my experience most budding electronics engineers want to 'specialise' in digital, "give 'me' a requirement and I'll write you some VHDL" they say. It makes me wonder if universities and colleges still teach the classical stuff (?). Getting hold of a skilled analogue person is difficult for companies, and the ones that are equipped with the knowledge and experience tend to be the older sort.
I cut my teeth on valves at an after school club, and took it from there.

I agree entirely. I started as an analogue designer when I left school in (ahem) 1968 and changed to digital after university to keep up with the world.

Very few digital designers learn the arcane arts or analogue.

Maybe I should re-invent myself in my fading years as an analogue only designer guru :-)

Re: That's not a sensor..

We're the same vintage and training, but I stuck with analogue. I started in medical electronics designing analogue PID controllers, later transferring to aerospace where I 'dabbled' with digital, but I'm still mainly an analogue person.

Re: That's not a sensor..

Is there still a significant need for analogue skills? Being ignorant of that side of the industry I rather assumed that everything had gone digital these days. And quite possibly largely commodified to the extent that solutions would be built from standard modular circuits. I would be interested - and rather pleased - to be shown to be wrong.

Re: That's not a sensor..

M'mm, I started with valves, too, at work, in 1962. TT23s, for instance, D3As, and then there were the ECC83s and ECC81s, EL84s, EF86s. I think I may still have a bag of them somewhere! The year I started the first solid-state RF power transistors were being played with - 120 Watts at about 100 MHz. (100 MC/s?)
I remember the big tape recorders at BBC - BTR22s (22?) and Ferrographs. I had a Vortexion.
Oh happy days......

And then there was my Zeiss Ikon Contaflex, followed by my Pentax S1. Which Is till have, and is in working order.

OMG, I'm really getting old, now.

Oh, and yes, there is still a need for analogue skills, for instance, in theatres, and some medical instruments, vibration meters, sound level meters, etc.

No KT66's or KT88's?

Valves are making a big comeback so maybe you should get back into the business.

I worked at a place where they bought a 110v 60Hz generator. No moving parts. It was a 6 foot rack with a stupid big transformers and more KT88s than you could shake a stick at. That's the way to do it!

We had a valve mono Ferrograph at home when I was a kit. That replaced various Grundigs and was in a different league. I swear the capstan flywheel was still spinning at breakfast from playing a tape the night before...

Now I use resistors so small that there is no space to write the value on them. That is, as they say, progress...

Re: That's not a sensor..

I was lucky to work at a factory in Kingston upon Thames where the PA system had 24 GEC KT66's in the output stage, and a bunch of GZ34 rectifiers.

These were changed annually without fail as the PA system formed part of the fire alarm system, and so was never switched off.

When the PA system was replaced I was lucky enough to scrounge all of the valves for my own purposes, and still have a few left to keep my Quads going!

(I should add, the factory was pulled down around 1980, and is now where Nikon UK is based, opposite to the site of the old Hawker Siddeley aircraft factory.)

No, they were/are audio valves. TT23s were VHF transmitting valves. (I was a radio engineer, working on the 2000 and 6000 MHz (900 and 1800 chan) GPO telephone transmission system.)

Had a spell at Eddystone Radio in Brum, too - now there's a famous name for you!

BTW, mistook - I should have said transistors 10 W at 100 MHz amplifiers
