OK, you are absolutely right. I stand corrected. I was looking at the comparator as operating in the linear region. Thank you for the correction. (tail between my legs).

Yes, of course it does. I didn't say the design wasn't moving in the right direction, I just pointed out that if you drive a FET gate with a comparator without a PWM circuit in there somewhere, even that circuit will work, but only as a linear regulator.

It is not anything but a linear regulator without a pulse width modulator!

Perhaps, but I'm likely to think because of the detail of the block diagram (comparator block, etc.) that a block labeled simply "Gate Driver" is a simple circuit biasing the FET. A Voltage to Pulse Width Modulator would be a more appropriate name. Because of the simplicity of the original...

NO! This will not work. This is only a linear regulator and for the current output you need with the input voltage you want, you will likely burn up the FET. In order for this circuit to work your comparator needs to drive an oscillator (perhaps 30khz-100khz output) that has a pulse width...

In order for this to be a Switching regulator Rives suggestion in post #2 is your very best bet. There are specialty ICs that have all the essentials you (some including the FET) that give you excellent performance. With the Voltages and currents you are considering I would STRONGLY suggest...

I've been reading up a little on IC1101, the largest known galaxy and there is not a lot of info on it, but it seems to have an unusually large mass to light ratio according to this popular article (see half way down): According to this article at 20kpc it's got 12:1 mass to light, at 200kpc...

OK Got it. I meant to ask this earlier, but when you say convention can I take that to mean, we have a timeline, and we can pick a point on the timeline and call that the present moment and so work from that point. If so, then yes I understand that and am certainly not resistant to it. I...

Please don't close it just yet. I still do not understand how there can be different nows on my worldline. If I were to draw a light cone, there would only be one now, the point at which the cones connect. There is only one present moment at anyone time, so how can there be multiple nows...

I was referring to this in post #31 So I am referring to the one plane that is perpendicular to the "world tube". As mentioned, this plane represents simultanaity or the present moment. And here we have: So to be clear, there are two planes, my now moment having one plane intersecting her...

Yes, but not "now". There seem to be 3 points that are all happening now, where I am, where she is now (which is the same location as my plane slicing through her), and the now moment represented by her plane slicing back through my timeline (at a different angle than my plane) which is suppose...

Take the now moment on my timeline and the plane that slices through your "tube". If that plane intersects another timeline not parallel to mine, can I say that is where that person is right now on her timeline? I think you are saying you can. That being the case, we are both in the present...

I re-read this thread I started 7 months ago and I must say it makes a great deal more sense to me now than it did back then especially with the added information from this thread. Here's what I've learned so far. 1. The block universe is really just the "amber" as Dale so eloquently stated...

I see. So the popular depiction of time moving being shown as a slice moving forward through the block is not a correct picture?

There must be a now somewhere. A slice somewhere. I am living in 2021 now, not 2019 and not 2023. I am at a point in the block universe, no?
