when I previously took MY TIME to tell YOU about many issues in your design, you just bulshit me in response.

well I thank you for taking that time, but I thought thanking anyone who takes the time is inferred and doesn't have to be repeated infinitely.  I always appreciate that.  In any case, all your suggestions were trash which distracted me from the thanking part.

[artbyrobot]

OK, let's take a look at your so-called "schematic":

(Attachment Link)

Now, do you really think that this is the form of drawing electronic circuits that's going to be taught all over the world in PhD level classes? That this will become the new standard? That this some kind of groundbreaking advancement in circuit representation?

Because if you do, then you're just batshit insane. (Which it seem you may well be in any case.)

Do you think there might be a reason that almost everyone in the world (well, except for the "instructables" idiots) uses standard schematic symbols in a standard, easy-to-read and easy to understand format? Do you think anyone is even going to bother to try to follow this diagram?

It's shit. Pure shit.

Correction:  this diagram style is elite and world class.  Any person from total beginner to 50 year veteran can easily read and understand it.  It is 50 times superior to the trash schematic style that is industry standard which doesn't even have drawings of what the parts look like.  It also is all straight lines and right angles which is harder to follow with the eyes and looks like a mess.  It's as if the people who came up with that were completely incompetent fools.  Thankfully, I have demonstrated the correct way to make a schematic.  Note also that I have been able to put extensive notes into the schematic so that it is very informative and you never really see that on standard ones which is all the more reason the standard style is so trash.  The standard style may be converted to from my style only when designing the final printable version in CAD for making it physically but my style is better for the conceptualization and learning phase and is more human readable.

In any case, your preference for a different formatting is irrelevant.  They question was what is wrong with the design itself, not the manner in which the formatting displays the design.  That part is not relevant to the functionality of it or the logic of the parts and routing.

The arduino will read the voltage output and switch on and off the highside switch

As drawn, your highside MOSFET will never turn on.  As drawn, your highside gate voltage is non-existent.

Don't believe me?  Build the circuit and test it for yourself.

Refer to the attached PDF for gate drive techniques that actually work.

so your crowbar circuit shorts the power supply then what?

when it shorts, a fuse blows and the thing is deactivated since it was outputting too high a voltage so something went wrong.  I'd then have to replace the fuse and test and figure out why it was doing that I guess.  It's supposed to be a safety feature.

[artbyrobot]

That's what I had been thinking,  that uC outputs aren't high power drivers.
   Probably you could find/select one type that has SOME pin outs with your good power.

Nice narrative though;  just pour the stuff over it,  and done...

well I learned you just solder a little baby logic level mosfet onto the big non logic level mosfet and this baby mosfet acts like the switch to the switch, opening up a sufficient voltage power source to feed the non-logic level mosfet for you.  So it's like a little buddy that helps the big mosfet turn on since the microcontroller is too weak to do it by itself.  The whole system is flawed though.  If I were in charge 80 years ago, all mosfets would be logic level because all microcontrollers would output enough voltage to turn all mosfets on - this would mean microcontrollers change or mosfets change but leaving them both incompatible was a horrible decision made by incompetent men who came before me.  And I scoff at those men.  They should be ashamed of themselves.  They have left a legacy of incompetence and folly.  Men of excellence like me would have never put future generations through this curse.  So now I have to clean up behind them like I'm changing their dirty diapers they left behind for us to deal with.  What a JOKE.

I already explained that the mosfet itself will be modded and potted to make it logic level before it goes into the circuit itself.  This way all mosfets are logic level mosfets that come out of my part bag because they aren't stock.  They should have been sold this way to begin with though.  So that concern is already addressed.  Looking for other concerns that are valid.

Also, humans already existing does not solve the problem of our gross lack of slavery.  It was abolished.  News flash.  And I'm glad it was.  But it is missed.  It is a tragic loss for the slaveholders.  I need slaves to accomplish my goals.  And I'm against human slavery (with some historical exceptions that were ethically accomplished and the slaves were in total bliss the whole time).  The perfect solution is robots.  Robot actually means slave.  I love slavery but don't love human suffering.  So I hate human slavery (of the unethical sort).  But I love ethical slavery.  I love robot slavery.  And robot slavery is ethical unless you are a delusional maniac who thinks robots are living souls with consciousness and real feelings.  I feel sorry for someone that blind and ignorant.  I'm not one such.  So I'm able to enslave robots to my hearts content and these machines could care less about it.  They were made for it.  They have no skin in the game and aren't able to care.  They are just are code executing.  They are not living at all.  I should not have to explain this to you.  You need to watch less sci-fi movies and do more theological studies.

What lofty goals do you have that require slave robots? Surely not folding laundry.

There is very little I can do to improve myself.  I'm already sitting near a maxxed out state of being.

You have lost me.

now imagine that sound while the robot pets your hair on your head trying to put you to sleep at night.  Not even earplugs would help.  You'd not get a bit a sleep that way.  This is why metal gear servos should be BANNED from humanoid robots.  EVERY DESIGN using them is wasting everybody's time because it creates a final robot that CANNOT BE USED INDOORS and therefore is SETTING THE INDUSTRY BEHIND and MISLEADING NEWCOMERS into thinking metal gears are okay when plainly they ARE NOT OKAY.  This then forces the newcomer to go ALONE into figuring out how to achieve silent actuation *I raise my hand*.  So this responsibility to address the incompetence of those who have gone before me has fallen on my broad shoulders and I have to go it alone.  The incompetent men who preceded me I'm having to clean up behind them once again like I'm changing their dirty diapers.

well I learned you just solder a little baby logic level mosfet onto the big non logic level mosfet and this baby mosfet acts like the switch to the switch, opening up a sufficient voltage power source to feed the non-logic level mosfet for you. 

You need 165V to switch on your highside MOSFET (i.e. 10V over your 155V main voltage)

If you don't understand why, then you need to do some more learning.

Don't believe me?  Build and test your circuit (or simulate in LTspice)
 

[artbyrobot]

What lofty goals do you have that require slave robots? Surely not folding laundry.

well I have shared them on my youtube channel but here's a few of them:  I'd like to create robot arms that come out of cars so when you pull up for gas, the robot arm comes out the side of your car out of a secret door and it swipes your CC and selects the right kind of gas and then grabs the gas nozzle gun thing and unscrews your gas cap and puts the pump thing in and fills the gas.  You never have to get out of the car.  It does it all. 

I also wanted to create a robot deer that hunts deer, skins them, eats them, converts them into beef jerky, then packages the beef jerkey, then poops the package out at your house when it comes home so you can open the package and eat the beef jerky.  (well deer jerky in this case)

I wanted to create a robot shark that eats fish and then freezes them and delivers them to shore on demand for you to just collect and make dinner.  No fishing required and food just always waiting.

I wanted to make large underwater whale robots that have onboard humanoid robots inside them that raise crops and livestock inside the whale robot and this way you don't have to buy land but can have lots of free food being made under the sea.

There are hundreds more like this and an infinite supply of these I can come up with if I decide to come up with cool stuff to make.  My imagination is endless on great ideas.  But I'm just one guy.  I need a robot army to bring these ideas to life.




As far as my having little to do to improve myself, I mean this:  most people have a list of things like: manage my time better, lose weight, start pursuing my dreams I have put off, etc.  Well I already did those things so I have no more things like that to check off.  I'm maxxed out.

I mentioned this earlier but nobody seems to have noticed it, so I'll put it out here again:
I had a flash yesterday what this is all about. It's the movie A Beautiful Mind.
Especially the scenes near the end in his garage. Remember that?

Pretty serious stuff if that's the case. So what do you all think?

(Except as I mentioned before, this guy's no genius like John Nash was.)

I don't know how to simulate in LTspice and my understanding is that this program would take a prohibitively long time to come to understand enough to do this and would therefore be a waste of time for me to invest that much time when I am just doing it for like one circuit in my life and never will use it again. 

That said, I understand what you have shared here completely and have updated my circuit to reflect this.  Once again proving I do take feedback and make changes if the feedback is correct (VERY VERY RARE).  And thanks.

I found the clip you are referring to:  https://youtu.be/jatIBalbcV0


But your theory is wrong.  I don't see imaginary men in black hats with suits on.  I don't let imaginary people watch my kids while the kids are underwater in a bathtub either.  I also don't have anywhere near that amount of notes on my wall.  Oh wait... okay maybe I have about 75% that amount of notes on my wall but still...

[artbyrobot]

Here's my updated switch mode power supply design.  It has changed many many times as I learn more and find my mistakes.  It is perhaps significantly different than the one that was shared and examined here earlier today.

Can you upload that to Digikey and get a BOM quote?

[Kim Christensen]

it seems you posted the wrong graph.  We'd want a graph that shows the voltage and/or amps relative to the Vgs, not the Vds.  The voltage from gate to source correlates to the amps and voltage of the drain to source is what we want to know.

I suggest that you look at it again. 

Hint: There are multiple lines on that graph. Why is that?

Still garbage and still won't work. You are a charlatan (with your BS claims of elite/inventor/etc).

Now, your other businesses (the successful ones  ), still waiting to see their products and websites etc.

Ideally, I want the mosfet to turn on when the voltage gets too high.  I want it off when not.  You are saying that even when it only has 5v or w/e it will be part on.  I'd prefer it fully off till 10v it hit.  I don't know how to do that.  Although the voltage during normal use may be even below 5v right?  not sure i'd have to look at the voltage divider circuit to see.  ideally it's so low the thing is pretty much off and may just leak a tiny bit I guess.  Something like that.  The tiny leak should not hurt anything.  That is my assumption.  I saw what I saw on the chart and stand by my assessment of it for now.  I don't want to spend any further time studying it again.


Edit: update:  lets say it does leak too much when I want it off.  So it blows the fuse when its not supposed to.  in that case, I can either solve it then, figuring out some work around, OR I can just remove the whole thing.  Safety circuits are for losers anyways right?  I took off the tipover switch on my space heater and removed the thermal shutoff safety device too.  They sucked.  When I was a kid those things didn't exist.  You just were careful not to tip the heater over.  That simple.

Ah, you speak of being galvanically isolated.  I don't think galvanic isolation is necessary and it adds unnecessary weight and complexity.  It is overrated and not wanted nor needed. 

Such arrogance stops you from investigating the topic of isolation.  Arrogance is an impediment to learning.

In this case, galvanic isolation can potentially aid you with solving your highside gate drive Vgs.

having an opinion about galvanic isolation has nothing to do with arrogance.  When doing personal attacks, focus on that.  When discussing specifics of some scientific principle, keep the focus on that.  I have many reasons why I think galvanic isolation is not necessary.  Basically, the idea is if a mosfet fails to on and welds itself on internally, in theory, your entire circuit would now just be 120v from the wall outlet.  It would stop being on and off regulated by the mosfet.  galvanic isolation would have a transformer in the way so that when a failure like this happens, the side of the transformer closest to the wall would ensure the wall shorts itself which would trigger a fuse blowing or circuit breaker blowing and everything is now safely off.  Got it.  But I don't see the need for that.  If my whole circuit did that, my crowbar circuit would blow shutting it off anyways.  So I avoided needing a high speed switching transformer in the mix and greatly simplified my circuit by eliminating that part and made my stuff way lighter in weight too.  Since a switching transformer that can do very high amps like I want would be prohibitively BIG making my whole power supply huge.  I don't want a huge heavy one.  I want it very tiny but with a george foreman punch.  The tradeoff is you have less safety built in.  Big woop.  That's why you throw in a safety fuse here or there.  Even if the whole thing became 120v, as long as I'm not touching that I'm good to go.  I don't see the issue.  Again, arrogance need not be mentioned.  And is a false accusation from you anyways.  Totally irrelevant.

Yes, with a gate voltage of 5V the MOSFET will be partially on, and with 155V across drain-source, it will heat up and let the magic smoke out ASAP.

If your voltage divider gives the MOSFET's gate 2V (Below turn-on threshold) when all is normal (18V), then the gate would only have 4V on it if something fails and the output rises to 36V.
ie: The voltage would have to rise beyond 36V before the MOSFET really starts to turn on. Therefore, whatever 18V devices that you're protecting will be dead milliseconds before your crowbar operates.
For a crowbar circuit, a SCR, zener diode, capacitor, and a resistor are all you really need. Google "SCR crowbar circuit"

Your incorrect and arrogant assumption is that galvanic isolation is purely for safety purposes.

Galvanic isolation is sometimes required for circuit functionality. e.g. highside gate drive

[artbyrobot]

with 155V across drain-source, it will heat up and let the magic smoke out ASAP.

no, it's a IRF 840 rated to 500v across drain-source.  So 155V across drain-source it would yawn at.

If your voltage divider gives the MOSFET's gate 2V (Below turn-on threshold)

the 2v turn on theshold doesn't mean its fully on though and it is not fully on till 10v.  so I imagine say between 2v-6v the amount on is so partial that the current flow is minimal and can be safely ignored.  So my crowbar would be okay to let waste power as a partial short circuit while the gate is only partially open like this.  That is my theory I have to look into more I guess. 

then the gate would only have 4V on it if something fails and the output rises to 36V....

ie: The voltage would have to rise beyond 36V before the MOSFET really starts to turn on...

whatever 18V devices that you're protecting will be dead milliseconds before your crowbar operates.

that might be fine.  in my circuit diagram, my 18v circuit feeds just a motor which can be fine at the 36v you said is the biggest threat involved.  Basically what I'm getting at is it seems that the behavior you described of my crowbar can be fine.  the downstream stuff just has to be able to handle these worse case scenarios momentarily before it crow bar does its crowbarring and everything is shut down by the crowbar's fuse blowing.  And my assumption is the most likely cause of this would be a mosfet failure causing the full 155v to flood the whole circuit momentarily (well beyond 36v so plenty to truly turn on that crowbar mosfet and plenty then to shut off everything and not gradually like you said but more likely instantly so downstream stuff doens't suffer really but crowbar happens right away.

For a crowbar circuit, a SCR, zener diode, capacitor, and a resistor are all you really need. Google "SCR crowbar circuit"

I prefer to invent my own crowbar circuit to pave the way to more options of ways to make a crowbar.  Another upside is if I design it, it means I understand it.  Understanding what is going on is important for me.  At least I prefer it over black box.  I'm ok with black box often but not for something safety critical I guess.  I prefer to understand it.  My assumption is a SCR is a unknown.  Never heard of that acronym.  So I might now understand that.  So I prefer to not go that route as it is foreign to me.  And I prefer not to look up that google search suggestion if my existing solution works already and from what I can tell by what you wrote, it seems it will work fine.
