The post below got me wondering.
I am currently learning to program ARM MicroControllers on an NUCLEOF411 dev board.
Awesome little board; ($13 at DigiKey)
- 512KBytes Flash
- 128KBytes SRAM
- Arduino UNO connectivity
- On board programmer/debugger
I'm learning one section at a time, currently the clock system. Very versatile.
Question: Would a series of articles on the ARM be of interest here?

Definitely!

I've got some M0, waiting for the boards so I can try to mount them.
Learning to solder using rework station for surface mount devices. So far I've managed to do 8-pin devices decently so I'm going to attempt some 32-pin m0's. Created some very simple boards to mount the devices on from JCLPCB, should be here next week and then I can make the attempt.
Really liking the ARM chips, but there is a bit of a learning curve; the chip, the STM32CubeIDE and the docs.

Well it is M3, after all.
I do agree, the M0 is sooooooooo simple. I like it very much.

I'd love to see such a series, Mike. I've got a set of DrDuino boards here that I built, but never got around to using for lack of ideas. Any projects around these powerful little MPUs would be great to see! Go for it!

Hi Roger, Are you aware that "Honey the Codewitch" posts long, brilliant, technical, essays on microcontrollers/programming here on the Lounge ?
Said HTC has resisted all attempts to get HTC to post on technical forums, rather than the Lounge, evidently in desperate need to get attention. In fairness, I should add that the Lounge has become much more a place where many people, including old-timers, ask specific technical questions of the types that used to appear in qa and language forums. HTC is the extreme case of using the Lounge as an ongoing technical blog.
Who the hell would want to moderate this forum, anyhow ... herding cats ? 
HTC is also publishing articles here that are winning CP awards..
Check HTC out.
cheers, Bill

Oh, yes, and I quite enjoy reading them. She reminds me of me, 40 years ago, enthusiastic and having fun making electrons jump through hoops. She's the reason I have, finally, a real keyboard and not one of those nasty plastic bubble machines.

Hi Mike, I absolutely look forward to your articles !

Definitely of interest to me Mike

In which direction your experiments will go?
a.) Switches (on/off)?
b.) Amplifier for signals?
|
|

in my mind, I target to logic gates of CPU type of things...
diligent hands rule....
|
|
|
|
|
And you are aware these are high current FETs, which are used usually to drive high current devices?
To do something like logic gates you don't need something like that.

thanks for your input. I selected wrong types of parts then

Well, a PSU would be a good idea, and a meter / oscilloscope is really handy.
After that, google each part you are interested in, and download the manufacturers datasheets - they normally give a basic circuit diagram which will tell you what components you are likely to require.

Since it's power transistors you will also need a heat sink(s), thermal grease and/or thermal insulation pads. (Depending of the type of insulation pad)
Then depending on your project you might want a bread board or a strip board for the low power components

it seems like I selected wrong parts for testing. thanks for your input...

Well it depends, a power transistor without sink will still work in low power applications, but if your driver circuit has to low current it might be slow due to high gate capacitance. (they're mos-fets)
And in that case you might fry the driver if used at a to high frequency. This is where you need maths.

It depends on what you want to do. Forgive me, but a transistor is such a basic component, it almost seems like a solution in search of a problem?
What I mean is, my natural response is to ask, "what do you need it for?"
I know that's not that helpful, but it's what I've got.
Now, if you want experiment with millions of transistors, in a dual core 240mhz configuration I can point you to a few MCUs.

Espressif ESP32S3 DevkitC at Amazon[^]
I use the MCU on this devkit for all new ESP32 based projects, and I use this devkit to prototype. There are variations that have more RAM but yeah they're basically the same thing.

resistors - you need resistors to limit the current when it turns on. less you hear and smell snap, crackle pop
as for the mcu - I'd immediately suggest a raspberry pi dev kit. I'm a yank, so I've been googling rasberry pi for years.
