Went off the topic in another thread. Starting here fresh. I think this deserves examination.
Naive and young for my age, I was seduced by Computer Science. FYI, CS has nothing whatsoever to do with computers. The "computer" in "Computer Science" is in fact a person, i.e. one who computes, or one who reckons. They should have called it "Reckoning Science." Only when it was too late did I discover that Electronic Engineering was a thing. That was what I should have studied. So the result is that I know very little about electicity, having dropped out of Physics early in the second semester, just as I was introduced to Maxwell.
I see this repeated, that incan can't do CC.
What I want to know is not if "there are no CC incans," but if it is absolutely logically and physically impossible in this Universe for incan to do CC, or if it is rather the case simply that no one has yet attempted, or no one clever enough has come along to create it. Aren't there three mode lightbulbs? Aren't they CC? Isn't the round fader on my mother's dining room chandelier CC? Why not an incan flashlight? If it is impossible, there are likely good reasons. But if it is merely difficult, then a little elbow grease, ingenuity, and perseverance could bring this into the world. So which is it? Impossible? Or merely difficult, and so far has not been attempted?
Let's try to avoid discussing or promoting the idea that PWM incan modes don't suck. PWM sucks, period, and it doesn't matter if you personally don't mind it. That it doesn't bother you personally is in no way a positive argument for PWM, but instead that is merely a positive argument for apathy. Also, even if something cannot be seen or detected does not eliminate the possibility that it can harm you or others. PWM is harmful to me, even when I can't visually detect it. So I want to head off at the pass those that are prodigiously loyal to their favorite flashlights despite the fact that they utilize PWM.
I really appreciate the sharing of knowledge by those that understand the stuff I don't. Thanks.
PWMing INCAN does not product visible effects and practically, does not produce any invisible effects either. It's a hot wire. It does not cool much between PWM cycles unless you were PWMing at a really low frequency which there is really not much practical reason to do..
Even for an LED, if the PWM is high enough frequency, again, there are no invisible effects.
