Let's just get back a little on track here - these things from ebay are beautiful but I have to be able to find the same components in the future too, if the clients wants to produce another 100 or 1000 units. My board should eventually go into an actual product.

That makes things a lot more difficult since there is a reason that these high tech components are so rarely seen in products. They are expensive! Only the high end specialized gear can justify the price of these components. Anything that you want to be able to buy in 1000 quantity in the next few years is brand new components that sell for there list prices.

Most of these old interesting components that people are showing here also carried a hefty price tag back in the day. A lot are custom made for one specific purpose, produced using lots of slow and fiddly manual labor, extensively tested to assure reliability. But now that they are old obsolete technology means that they can now only be sold as pretty looking objects rather than state of the art electronics.

Ah, if you may need to make a thousand, that makes a difference.

OK, yes, the colour coded RF coils are still sold, as are trimmer caps in various colours, I'd also throw in some big ass axial leaded resistors with pretty stripes, gold plate always goes down well and if you want a bit of added spice, maybe some colour coded gold plated test points?

You can always have copper and silkscreen art (Japanese book with an awesome Manga/Anime character etched into it and it was functional, think it was an FPGA book, it was discussed here recently)

Blinkelinghts, the tiniest SMT LEDs can impress if they're lit, maybe even include a small micro to make them flash in sequence, call it a test sequence or something.

There's a ton of scope for creativity here that could easily be harnessed and actually create visual art that works.

What can also work are gold plated (RF) connectors. ( like the ones used on RF modules )

For general public just put lots of 2W resistors (find a pretty color) and bare-copper inductors.



Lots of wiggly impedance-matched PCB traces, too.

I like these old TO-3 cases: https://www.digikey.de/short/3vtmp0


And the coil you are searching: https://www.digikey.de/short/3vtmzn


Of course, use only these resistors, or bigger: https://www.digikey.de/short/3vtmmr Nothing wrong with using a 10 W, 10 k pullup resistor for your microcontroller :)


Photodiodes look nice, too: https://www.digikey.de/short/3vtmb8

Old-style LDRs are cool as well, but more expensive.

Looks like they still sell these can-type packages, but expensive: https://www.digikey.de/short/3vtm50


And last but not least, you should have lots of fancy LEDs, like this: https://www.digikey.de/short/3vthcn


Unfortunately I couldn't find one of these old ceramic ICs with the gold traces on top, this would be the best. I guess you can get these only as collector items from eBay.

Challenge: create a circuit which does actually something useful with these parts :)

Yes, photodiodes! There are certainly some cool parts in this category, available and cheap
(check out this one, although a tiny bit too expensive: https://www.digikey.com/product-detail/en/luna-optoelectronics/SLD-68-026/SLD-68-026-ND/5423686 )

Instead of photodiodes, use IR detectors, as they also come in a metal can with a lid. As a bonus they still work if you power them, even without the fresnel lens they are normally behind, though they are a lot less sensitive.

Go to surplus stores or recyclers / scrap yards or even some places like Freegeek (or other that revive old hardware or tear them apart) and pick some old dedicated server power supplies or oscilloscopes , you'll find plenty weird planar transformers, chokes, inductors, opamps and ICs on ceramic substrates (especially in oscilloscopes), precision resistors on ceramic substrates..

You'll pay for weight or even nothing at all if they're stuff for very old systems that aren't rare and then you can just desolder the chips and you have your stuff. No need to buy new unless you don't want to bother with washing the parts or spend the hours to desolder them from existing boards.

Oh since you seem to be from Israel, you should check out Surplus Tech Smart, some company from your country which also has an eBay page : http://stores.ebay.com/surplustechmart/
  and they have an actual website with contact info : http://www.surplustechmart.com/

They were popular for a while because they listed on eBay damaged oscilloscopes and linear power supplies that seemed to have survived explosions or at least car crashes (military stuff i suppose)

Give them a call and explain your situation, maybe they'll be willing to give you some circuit boards or at least some hardware that has none or very little resale value. .. and maybe since you're from Israel as well they'll be willing to give you a more preferential treatment.

^ Potentially 1000 identical pieces required, new would be easier.  :P

You know my local market way better than me  :)
As I said somewhere above, for my current project I need a more dependable source for the long run, but this information will probably come in handy elsewhere.



Thank you all for your suggestions, I think I have enough to work with at this point!  :-+
