coolest looking components

My earlier posting did mention the Pirelli calendar!

[BurnedResistor]

Late 70s Burr Brown thick film hybrids were sufficiently pretty they made a calendar out of them. Pirelli for geeks

These look really interesting. Do you know what they did/what kind of circuits they where?

Their function can be guessed, to some extent, by looking at the sub-components. But the details are lost in time.

If someone compared the BB databooks with the photos, a more informed guess could be made - but I've neither time nor inclanation.  There were reasonable speculations the last time I referred to them in a thread on this site.

Those old British film capacitors with the dipped color codes/bands.

Hey, I took that photo. Fame at last

Silicon wafer

are there any like this with full 1920x1080 resolution? I just found me a new wallpaper.

[MudMan]

The picture in the post has 3373*2285 pixel. Croped and resized for you.

[XOIIO]

Derp, when I saw the more square aspect ratio of the original I just assumed small resolution. Thanks. Now I just need to clean my desktop off so I can see it past all the icons lol

[Seekonk]

This is what I thought a FLUX CAPACITOR should look like.  Recognize this?

Hi,

I have a couple of items to share.

PV2 Triode

The is PV2 triode is about as close as it gets Fleming's triode. There is a seal at the top of the envelope. The filament, grid and anode are clearly visible. It is a very simple structure and you can see it is very closely related to light bulb.

What makes this extra special, to me, is that it was my Grandfather's. He was interested in radio receivers.



This component is so cool that it has a heater 

Analog Device CMOS DACs

Not actually a component, but a cool part of analog history. This can is a promotional item made for analog devices. It was to promote CMOS DACs. You can not say it is part of Silicon Valley history, because Analog devices is in Massachusetts.







Cans like this one, were mentioned in these two stories:

Sheingold wasn't the only ADI employee subject to practical jokes. Pease noted how Analog Devices was touting Paul Brokaw's new CMOS circuits with a custom soup can. So Pease took the can of "CMOS DACs", drilled a small hole in the bottom and back-filled it with sea moss. He managed to solder up the hole in the can and sent it to Brokaw.

They hoped Brokaw would enjoy his "sea moss soup". Apparently he Post Office did not cooperate. When recently told this story, Brokaw says that, "I never got the SeaMoss. I never even knew about it until now."


Dan Sheingold was with George A. Phibrick and then Analog Devices.

Paul Brokaw was instrumental in the development of band-gap references, among other things.

Pease is Bob Pease of Philbrick and National Semiconductor.



Pease was not the only competitor to respond to the ADI CMOS DAC soup cans. Jim Williams and Jim Cecil bought a Big Mac, stuffed a bunch of National Semi CMOS DACs into the meat patty put the burger back in its original box and sent it to ADI's Dan Sheingold with a note, "Enjoy your Big DAC attack".

Sheingold told Williams that the burger "was a bit green around the edges" by the time he got it.


Jim Williams, Philbrick, National Semiconductor and Linear Technology.

The can is empty.

The parts listed on the can are:

AD7533 - Still in production from Analog Devices

AD7542 - Still available from Analog Devices

AD7541 - Analog Devices

AD7524 - Analog devices and TI?

AD7523 - Obsolete

AD7522 - Obsolete

Heh.  I forgot where I got it.  Must have been here.

[Jay_Diddy_B]

Hi,

I have some of those film capacitors. I can still read the colour code on sight 45 years later. They were sold in England branded as Mullard (part of Philips)
250V and 400V ones were common.

I used to buy a bag of factory rejects, from N.R. Bardwells, 288 Abbeydale Road, Sheffield U.k. The rejects worked for the most part, but had cosmetic issues.

Forum members in the South Yorkshire or Derbyshire area will probably know Bardwells.

The c280 series  has become BC components MKT 366, but they lost the stripes.

This is technically a vacuum tube, for a cyclotron.  Does it count?   

I am waiting for someone to say "real components have curves"!

[timb]

I've always loved the PCB etched inductors found in old Tek gear:





(That's the 5-2-1ns output board from a TG501 Time Mark Generator.)

[rsjsouza]

I love EPROMs

[Artlav]

Huge soviet vintage military tubes.


With visible plasma inside.

[T3sl4co1l]

Radar modulators: for when you need an IGBT, but they haven't been invented yet...

[Kilrah]

With visible plasma inside.

Beautiful!

I love EPROMs

I hate 'em. Not because of the way they look but because of the hours they added to the code-test-debug cycle when I was working on that one firmware project. 

[cloudscapes]

Always a fan of nixie tubes, and space-ready electronics!

Relaxing to just sit and look at. 

[lowimpedance]

And just to add some not to common POTs to the collection.
first up is a SINE/COSINE POT or probably more correct to say SLIDE WIRE ? (continuously variable with no end stops), with a garden variety 10 turn sitting on top for size comp.
next is some 'little' power wire wounds and two more somewhat smaller slide wire precision pots.

And how that has anything to do with the subject of the thread?!?

So, basically, it is a TANGENT POT!
