What analog projects are you after in 2022/23?
VSV_electron:
I decided to comeback to electronics spontaneously without much thinking about what I was going to do. I had a very vague idea of the knowledge gaps I wanted to fill mostly in the analog electronics as I consider it the most exciting part of the hobby.
They still manufacture transistors! - That was good news.
However, as it became apparent to me everyone seems to move into the digital (aka Arduino) territory and no one is much interested in analog any longer except for some specific areas such as tube amps and other guitar stuff building.
So I'm sitting here and thinking about what analog projects it's worth undertaking and learning about in 2022 and upcoming 2023. I'd like to be able to start from scratch, design a circuit, make all the calculations and implement it. Since I was mostly interested in the transistors in the amplification mode what should I be looking for? Nothing but sound amplifiers comes to mind but that's too limited task in itself.
In the old day everyone was building am radio receivers (I built one myself when I was 12) but who's working on them these days?
Anyway - what are your interests in the analog electronics in the age of total MCU dominance?

Analog computing to solve differential equations.
RJSV:
I need a good analog design person, (alas not up and running, business-wise), that's optical analog, interfaces, speed switching options, knowing the trends in highest speed photodiode, or ??? That means some sort of non-semiconductor switch core, perhaps nano-meta material.
Best would probably have background in optical networks (digital, sorry).
I have method(s) doing low level, BOTH digital and analog...To the degree unique that it's, actually, really FUN, to work on, and confusing at same time.
One of the passive computational elements will do a multiply, of a digital word, X times an analog word. The analog word 'representation' has similar BUS segmented or separated 'beamways'.
Oh, and the work also demanding 'skill' in making up new tech terminologies...like 'discrete analog shifter',
or 'Flux Capac... Oh wait

I see the point of the joke but...
I recently watched a YT presentation of an "Arduino expert". He discussed two different types of relays to use in "Arduino" (I'm sure he is unaware of what that actually is in essence).
So he went: "Here you see 2 types of relays: the first one is (showing an electromechanical one)... ehhh - Let's call it the "old type"... The second is (showing a solid state optocoupler one)" - Let's call it the "new type". So, if you don't want to mess with a diode (a really scary thing), forget about "the old type" relay...
Isn't that the beauty of the Arduino world?

By the way, jokes aside... it just occurred to me that in your sarcastic reply (which is really spicy and funny) there is some rationality. Back in my University days we did some lab calculations on the analog computers to simulated behavior of the control systems implementing various methods of regulations. That was very interesting. Not sure if I'm ready to build an analog computer though :-)
