Does the robot need a million mile extension cord?

the robot will use battery power most of the time except when it's near an outlet and chooses to plug into said outlet to charge while it happens to be in the vicinity of one.  While doing this it can use wall power to power some of its activities but will tap into battery power when it needs more watts than the wall can safely supply before blowing a circuit breaker.  So it won't pull any more than a conservative number of watts from the wall power just to play it safe since most wall outlets are part of a circuit already using a significant amount of available amps IMO.  So lets say 500w is a safe number.  This would only power like 4 finger motors in typical use I guess.  So wall power won't be great for it due to being too low in watts.

In any case the extension cord will only be about 6-7ft long and will be retractable and wound up in its body.  I was thinking maybe lower back is where it will come out.

However the biggest source of power will be its battery backpacks which it will strap onto its back like bookbags and it will have several of them and each of them will plug into wall outlets and charge at all times and it will hot swap them on like you do with cordless drills.  This way the robot will have 24/7 uptime and never have to stop its work to charge.  It will be technically charging many parts of itself always having many removeable battery backpacks always charging while only using one of them at any given time.

It will also have onboard batteries which will provide reserve power when a backpack is not in use momentarily.

I liked the crowbar (redrawn circuit attached):
..

Looks like you left out the fuse on the front side of the crowbar.  Does the robot need a million mile extension cord?

Ah, yes, forgot the fuse.. Maybe because fuse is usually found before the bridge rectifier. For good reasons by BTW. First, it makes sense to have fuse at the AC input before any other components. Second, it allows the use of cheap fuses, which are not rated for high DC voltage. It is harder to interrupt DC and fuses get more expensive. Anyway, original is attached.

did not know this.  You have officially added value to my project and I will take this advise.  Sound logical and reasonable and is objectively factual, not pure speculation.  See, I do take advise when it is clearly good and not rubbish like 99% of what I've read.  This is now the 3rd time I believe I've taken feedback and changed course by it here on this forum alone.  So all accusations I don't listen to feedback need to stop as its clearly a lie.


edit: update: actually it was not the best advice and I explain why in a post below.

Can't your robot's AI solve the worlds energy problems?   It seems like they should be able to make their own power.

I liked the crowbar (redrawn circuit attached):
@artbyrobot, do you agree, that this power supply is trash and nonesense?

You say you liked the crowbar.  Are you suggesting sarcastically that this won't work?  If so, what is wrong with it?
I designed this elite power supply.  You are saying it is trash and nonsense?  Why so?  I think it's great.  What is wrong with it?

Take a look at the attached. To the left is the typical "Output Characteristic" of a IRF840 MOSFET. Can you tell us how much current will flow in the drain when there is 5v between the source and gate? Your circuit is supposed to "trigger" when the gate voltage reaches 10V, but MOSFETs don't work that way.

I'll make it multiple choice:
A) 0 Amps
B) More than 6 Amps
C) 6 Amps
D) Kaboom!

Your power supply (I'd call it garbage vs elite) will never work. The 'buck' converter is trash. Explain how it will actually function, explain how the gate drive will be accomplished, how the firmware will regulate and what the control loop looks like. If you think it is perfect and ask what's wrong with it, you are clueless and dangerous. Instead of asking what's wrong with it, try instead to explain exactly how it will work and provide component values and some design calcs showing your analysis of the proposed control loop.

None of that junk is even conceptually correct. It is at the same level of garbage (vs elite) as the rest of the things you've shown on this thread, your website etc.

I ask again for you to show us the products from your other businesses and any links you have to their websites - though maybe they are also top secret 

I really wish your power supply remained top secret so that some poor soul doesn't actually try to build any of it.

Keep on digging - rabbits have nothing compared to your ability.

Oh, and this junk you have documented, this is the culmination (so far) of 10 years of your R&D work?

And finally - please come out of the closet and admit you are taking us for a ride.

cheers,
george.

This is unbelievable. When I just casually said something pretty random (not even directed to you, simply for the forum), you are thanking me! And when I previously took MY TIME to tell YOU about many issues in your design, you just bulshit me in response.

Yes, it was sarcasm. Honestly, most of the circuit will never work. What's wrong with it??? Build and see yourself. Cause you don't know how to listen, respect and value peoples feedback.

[Analog Kid]

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



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.

[Manul]

It is important to note that it's not shit because of the way it's drawn (although, it's an abomination). Furthermore, it's not even shit. In my dictionary "shit" is something of low quality, low performance or unreliable. This is a different category, it's a bunch of (lacking and wrong) concepts put together into a "design" which is naive and absurd. It's not even that it needs fixing here and there. It's "Ctrl+A, delete" way of bad. Go study everything from beginning.

I wish he would make something functional and show it off to us. Yea I know you made pulleys and tugged on the lines wrapped around them. That ain't even close to what I mean.

I mean a functional system of inter-working components. Like the power supply - build the damn thing and show us how it works with a load, or a microcontroller that's .. wait for it ... controlling something. You soldered flat ribbon cable to one but what of it? What have you done with it? Or a software component that's doing something active that's interesting and purposeful - not 8 hours of you typing in code on a screen that hasn't been shown to do anything at all. You think it will but you really don't know it will.

You've just got one little project after another that veer all over the place and nothing really that works together to perform anything much at all. I just do not see any logical path you are following.

[Bud]

OP could make a fortune by framing that power supply drawing and selling it as steampunk art.

actually, on my way to church I was thinking about this issue and realized I was not wrong after all.  A fuse before the diode bridge rectifier would snap if the overall amps of the system were too high but would not snap if the voltage grew too high in my output.  So it would not serve the purpose my crowbar circuit is designed to do and would not protect against too high voltage output after all.  So it would not do the job I want.  In some earlier iteration I used to have a fuse like what you are talking about before the diode bridge rectifier but then realized I don't need it and the crowbar is enough.

[artbyrobot]

To be fair, the compiler doesn't care and will produce exactly the same code as calling your variables x, y, i, etc.  It would be better to take the piss out of something that actually matters.

The voice of reason joins the conversation.  Steve, a hater, has unwittingly just exposed and shut down another hater in that haters complete ignorance.  It is fun to see the haters devour one another this way exposing their own folly to eachother.  Makes my job a lot easier as a hater humbler myself.  The haters can humble eachother exposing the ignorance of one another.  That's ideal really.

[artbyrobot]

Is there some actual, executable code we can take a look at

just the videos.  I mean I could share a executable code program I've made but it would not be the ai or anything related to ai.  But not sure if you want that.

[themadhippy]

so your crowbar circuit shorts the power supply then what?

[artbyrobot]

Even though in my opinion, just showing great progress with elite skill should be enough evidence even at my current stage of development

I noticed a positive progress on your last few replies. You didn’t add more words like "great" and "elite”.

I mean, what do you think of me if I say the following?
I, the great engineer, discovered in year 1979 how to build a DSB-SC demodulator which is simpler and more reliable/practical than the known ones that are based on Costas Loop or the Squaring method. Even in these days, the scientific world, as of IEEE, is still ignorant about it.

Well, I personally hate myself if I say it. I would say instead:
In year 1979, I had the chance to build a simple practical DSB-SC demodulator. But since, in general, there is no more interest in DSB-SC system, there was also any need to add the topology of my demodulator, which has no I-Q signals (as used in Costas Loop) or a hi-Q selective filter (as used in the Squaring method), to the two known ones, at any university.

But I have made great progress and do have elite skill so stating such in the face of bullying and unfair criticism is justified especially when I have explained I'm being a bit playful at this point since the serious tone had to be removed when I'm not allowed to express myself in a genuine full way since I can't talk about my religious beliefs here.  So I'm forced to just be more playful and non-serious with these constraints on my speech.

[artbyrobot]

Total garbage is what it is! I love the uC that will directly drive the FETs

I designed this power supply like 5 days into learning what voltage and amps are.  So at this time I did not know that some mosfets are non-logic level mosfets.  I assumed they are all logic level mosfets (and frankly, they all should be logic level mosfets and manufacturers are idiots to make them non-logic level IMO.  It's just lazy.  Slap whatever you need inside there to make it logic level and pour the black stuff over all that so it just works.  DUH!  Obvious.  In any case, yes, I'll be adding the 2-3 extra thingys to drive them and don't even need to bother to update the schematic to reflect this since all my mosfets I'll be adding these thingys to so that when I need a mosfet, it IS a logic level mosfet siince I will strap all the thingys to it to make it logic level and then pot those on or w/e - like the manufacturer should have done in the first place if they weren't completely incompetent.

Nice that the circuitry is non-isolated as well.

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.  I'm not going for UL certified consumer grade here.  This is for personal use.  Can you persuade me that I must use galvanic isolation?  From what I understand, it is a joke to pursue that.

I hope the OP never attempts to build any of it - it's a death trap.

I have already built 90% of it and you can see this build progression on my YouTube channel although its under my dust buster fix playlist not my robot playlist.  Also, I don't consider it a death trap.  Please substantiate your claim.

Note: I decided I wanted this power supply to make a AC powered dust buster that can run continuously off my custom power supply and this would act as a prototype for the robot's power supply.  Technically then the design and build of it should be under the robot building playlist and the dustbuster fix playlist but I had to choose one.  So I chose to put it on the dust buster playlist but to cover its design and build in later video recap on the robot playlist when I get to that phase of the robot build.

[artbyrobot]

Note my perfect soldering compared with OPs.   

There was some agreement that my welding was not clean looking.  But I already explained its because its a flux wire welder, not a tig welder.  People seem to not understand this fact or the difference.  My weld is solid.  That said, there has been zero mention of my soldering work being poor or unattractive.  This is the first I'm hearing of this.  I am under the impression that my soldering work is elite and world class.  Substantiate your inference that my soldering work is sub par.  Preferably with a recent example, not one from my first couple years of my youtube channel but one more recently.

[artbyrobot]

Normally people will grind down their shitty welds but in your case, there would have been nothing left holding the washers together.

Just repasting the pictures I uploaded does not provide us with any substantiation of your claim there was insufficient penetration of my welds.  You cannot prove this nor have even attempted to do so.  It seems you are ignorant about welding sir.

And here's now some counter evidence for the defendant I present to the court of public opinion:  I have used the same welder and welding tactics to weld the muffler to a muffler hanger for my car and I put that muffler hanging into the muffler hanger support clip thing and the muffler has hung and vibrated and put its weight onto this welded on piece of metal hanger for years and my weld has never budged.  It has held.  So this proves my welds are incredibly strong, competent, pass the test of time, and are world class and elite.  They look dodgy but perform NASA level.  So you are letting looks fool you.  This is ignorant on your part.

[artbyrobot]

Do you have any photos of the actual construction of this supply what you are willing to post?

I have the youtube videos about my dust buster fix as a playlist which shows the power supply being constructed.  It's not done yet but well on its way.  I don't have photos handy.  I'd have to go to the videos and screenshot or find the power supply in my shelves both of which I'm not willing to do presently but could do one day.

[Alex Eisenhut]

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. 

[RJSV]

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...

[artbyrobot]

The 'buck' converter is trash. Explain how it will actually function

a simple wiki search would tell you this George.  The Arduino will read the voltage output and switch on and off the high-side switch, charging up the inductor when on and releasing it when off.  Instead of a return diode which would have to be huge, it uses a low-side switch as the return line.  That switch has to turn on the moment the high-side switch turns off.  By altering switching speed you change the amps and voltage.  This is all basic stuff George.
