Human foolishness repeats in a loop. They’re both useful, even if you individually cannot perceive why.

Yup.

There are famous quotes from George Santayana and Mark Twain about that. Youngsters, if they know them, don't understand them.

It does have some impact to the way you use it and for a small knob encoder without detents if pays to use right thumb and forefinger and remaining fingers atop the scope to steady the hand.
Here instead of detents a larger knob would offer better control for rapid adjustment. I have in the past swapped in one of the other knobs which worked quite well but use it as stock and show customers that visit the best way to use it.

I hope to have mine apart soon for some PSU tests, specifically finding the DC levels and currents required to operate a stock unit for portability.
While in there I'll get the encoder info and I guess I need pulses/rotation too.
Pop me mail or PM.

No, but big touch screens with pictures are on the way. The twisty knob interface will be a thing of the past.

Along with glossy screens which pick up every fingerprint and massive problems with glare from the windows and office lights.

I absolutely loathe touchscreens and aside from something like a smartphone I won't buy anything that has one. I absolutely hate fingerprints on a screen, it drives me crazy. Most of them also have frequent issues recognizing touches from my fingers, I've never figured out why that is. Even my iphone sometimes doesn't respond.

--- Quote from: tggzzz on December 27, 2022, 11:20:46 am ---Classic OT example: try to get a Tesla salesman to show you how to switch on the windscreen demister safely (i.e. without taking your eyes off the road). Last one I asked only managed to switch on the seat heater; previous one had to reconfigure the GUI including dragging heiroglyphs/icons to a taskbar!

That's because you're asking a stupid question.

The correct way to do it is to press the button then say, "demister on"?

--- End quote ---

After five minutes spent failing to do it with a control, the salesdroid said he could do it with voice control. I said that would be OK with me; he tried, and that's when the seat heater turned on! I didn't bother to ask whether it works just as well while driving and where there's no radio connectivity (think Alexa!)

So, sorry, your suggestion didn't work - and the Tesla failures were worse than you imagined :)

I drove my dad's Tesla for a few weeks after he passed and I ran into the same issue. I loved the way the car drove but I absolutely hated the dashboard interface. Nearly everything is integrated into that big touchscreen, it is absolutely impossible to operate it safely without using the voice control which is another thing I really don't like doing. It tries to automate some things, like the windshield wipers but it's the edge cases where that fails to work reliably where you need to operating those things manually during times of high driver workload when it is least safe to try hunting around on a touchscreen with one eye on the road. I think touchscreens in cars should be illegal and physical controls mandated. My car has physical controls for everything, knobs, switches and sliders that are laid out logically by function and shaped differently. I can operate everything by feel without taking my eyes off the road even for a moment. It is a demonstrably superior interface but it doesn't look trendy and it is expensive to build.

Touchscreens in cars are marketed as high tech but the only real reason for them is they are cheap.

Never thought I'd be into them much for test equipment until trying a few and you should be aware a touch based UI is required for a mouse capable instrument.

Some instruments respond to touch, front panel controls and a mouse, including the scroll wheel and use of all 3 once you get in tune with it is much much faster than use of any of their individual input mediums.

Sadly until you spend some time with an instrument with this sort of capability you would never know.
