There are more ways to make a circuit not work, than to make it work.
That's usually JF's MO.

I have some 5V DC adaptors from ebay, with blue LEDs. Those are very bright. I also have some black write protection labels for 5 1/4 inch floppies. Put the labels over the LEDs, you can still see the LEDs through it, but no longer blinding.
One day I am sure those labels will be harder to find. The labels are on my audio amp and my monitor too.
You drew it wrong. Look again. It's a *booster*.
Your point about variable frequency -> variable current is worth looking into, but you do not understand the actual circuit at all.

That is not my circuit.
Bright blue LEDs are annoying.
You are always too eager to prove me wrong.
But it's you who are usually wrong. Like this time. And many others.
Good engineers don't let emotion blind their rational perceptions. And they check their work before they publish (or build) it.
If you enjoy being wrong in public, posting mea culpas in quantity, don't change a thing.
Hey, I thought it was my job to screw up and say silly things on SED. Kind of like a court jester.

--- Of course I don't enjoy being wrong in public, but when I am I acknowledge my error, learn from it, and get on with my life.
On the other hand, when you make an error - even a bald-faced one and are called to task for it - you immediately take the position that you're infallible and then vigorously stir the pot with the intent of finding the tiniest straw you can latch on to in order to steer the "discussion" in a direction - any direction - away from the focus on your error.
The purpose of all your machinations, of course, is to derail the discussion by changing the subject, thereby negating your need to account for your error and allowing you to continue with your charade.

Buy you are nice and funny and interested in things, and do interesting physics stuff. JF isn't interested in electronics or physics or economics or anything; he just wants to argue and whine. Which is why he jumps to dispute things, posting absurd LT Spice sims, before he thinks.
If you don't enjoy it, think a little before you post.
