@HP and Aleph. You win. Your world is the one every one inhabits. The more I try to explain the more you resist my explanations, and put meanings to the words that aren't meant. So yes, you win.

Not at all! You inhabit your world - we inhabit ours -- While both are very real - neither represents a 'default world' nor is either more 'valid' than the other...

Ya know... I have to wonder if 'socioeconomics' isn't as destructive a topic as politics?

In any event, there are neither winners nor losers in this sort of discussion/debate -- and certainly no cause for hard feelings!

Sincerely, very best regards
HP

PS -- For all that, should you (or any genuinely concerned party) feel we're neglecting 'low resource readers' -at any juncture- in our educational 'articles' please tell us about it!

Of course it can be.

Shortbus plz don't take this wrong way but I say if you get that ragey when ppl say your work is worth more than you think I'd be afraid to be around if someone said opposite!

HP and Joejester I agree! So let's everybody just mellow out cuz progress is too slow already w/o bickering over absolutely nothing!

Can do! - Howbeit I prefer to merely post the descriptive text in the usual fashion --as opposed to-- 'embedding' same within the images (MS Paint leaves much to be desired in the ways of 'user friendliness' and, indeed, functionality

HP whatever works! Cuz I want pics just to refer to when I ask questions on other threads

@Aleph(0), as you are aware, this is a phenomenally hectic time for me! I'll do what I can -- meaning I'll certainly capture and 'up' some of the images by early Monday morning! - But no guarantee I'll get 'round to all of them this week...

@Aleph(0)

So... I'm yet awaiting your input as to the necessity/advisability of a LV-PSU construction tutorial?

Best regards
HP

 

@Hypatia's Protege

So A0 clued me in that the projects are rolling again! Let me know how I can make myself useful? In the meantime I'll get caught up on the thread.

And I say you just don't or won't get it. The world at large doesn't work as you seem to think it does. Most people(you and HP not seemingly included) don't get to "set" their level of compensation for their work. Most only have two choices, (1) accept the prevailing wage(in my case the highest paid in the area), or, (2) don't have any income.

Hey @shortbus -- Speaking for myself (and I'm certain, for @Aleph(0) as well) -- I apologize that there seems to be a misunderstanding -- To be clear - no one is saying that (as an employee/contractor) one may always receive the desired compensation (that, of course, is down to 'supply and demand' dynamics) -- That said; one (as an employer) is always free set the amount of compensation paid out (granting that same meets or exceeds the employees' expectations/demands)

Most people(you and HP not seemingly included) don't get to "set" their level of compensation

@shortbus -- My point (and, again, I know that I speak for @Aleph(0) also) was merely that, inasmuch as I receive much greater income for much less arduous labour -- I feel the 'economy' is unjust - hence my decision to pay what I feel tasks are worth (above and beyond so called 'fair market value', etc...) --- That said, my work-related income is, indeed, based upon 'fair market value' as assessed for my profession...

Please understand that my 'quips' (Re: post #1135) were not by way of ridicule! -- But merely a 'knee-jerk' reaction to (what appeared to be) dismissive 'marginalization' of my views (via inflections of 'reality', etc...)

So... Yes! I accept your and @#12 's assertions to the effect that the salvage operators were 'paid' in excess of 'FMV' via the 'scrap value' of the steel alone -- But then I do not regard FMV as fair! FWIW my assessment of the value of services rendered by the salvage operation stands at a minimum of $120k - based upon past construction contracts... -- For 'reasons unknown' it seems 'FMV' for construction far exceeds that for demolition/cleanup - despite the commensurate labour intensity/hazard liability attendant thereto...

Hey @shortbus --- I hope we can return to friendly terms? - Hard feelings are unfortunate -in any event- but especially where owed merely to misunderstanding and 'high emotions' (on both sides)...

Most sincerely
HP

 

Well hey! Nice to 'hear' from you!

So A0 clued me in that the projects are rolling again!

Indeed! We're hard at it --in the intervals, that is, of our bickers as regards, for instance; scope safety, socioeconomics, the US tax code, or what constitutes equitable compensation for removal of 24 tons of stainless scrap, etc, etc, etc...

But seriously! We are getting there!

FWIW I've taken the decision to present the 'EHT Indicator mini-tutorial' as a construction example -- so composed as to be ready adaptable to various components, enclosures, etc... -- While, perhaps, less than 'elegant' I feel 'overloading' newcomers to serious study/design of EHT systems with the not inconsiderable burden of locating specific materials is the surest way of chasing them back to the sorry likes of 'Instructables', 'YouTube-U' and similar purveyors of 'recipies' and demonstration

Your thoughts???

In the meantime I'll get caught up on the thread

If I might 'crave a boon' -- Please! Take care to avoid 're-igniting' any of our recent bickers! -- Of course you are free to express your opinion but in a courteous manner sans challenge to or derision of others! -please-...K?


It is of utmost importance that this thread remain a friendly environment!

Very best regards!

What???? No, no, no!!! ... this thread reads like a soap opera! And I like it that way! ... you make it friendly and it's gonna turn boring!

@Aleph(0) --- Below are the requested images of the PolyPhos secondary circuit components -- Please note that the 'shopped in' component IDs are as per the derived schematic (at the end of this post) Please ignore PC board markings! -- I apologize that the images of the transformers are a bit dark (there really are just so many hours on the clock!)

Should you require further detail, alternate angles and/or additional information please advise prior to Wednesday morning!

Transformer detail illustrative of the floating windings and 'tape wound' iron core.

Here is the schematic of the secondary circuit (via 'reverse engineering' of same).
Please note that 'compounded components' are depicted as single-piece units...

HP major tnx!

HP I totally hate to ask but if u can find time plz upload pics of the xfmrs that show better detail of core cuz I know what they look like but I need to show other ppl when I ask abt operating frequency and like that.

So anyhow I say it's totally effing weird cuz XL(pri) of just 1mH is only 2πΩ at 1 khz so that's magnetizing current of like 29A rms for 258Vp sinusoidal excitation needed for secondary voltage of just 30kVp!

So cuz I've never heard of metallic iron core xfmr that's efficient for pwr conversion past 1khz it must be like you said basically ΔI/ΔT topology all the same a flyback and ignition coil? So IDK how that can be symmetrical to work with full wave doublers and anyhow wouldn't the hv pulsewidth be too narrow?

So... I'm yet awaiting your input as to the necessity/advisability of a LV-PSU construction tutorial?

HP Since you asked I say anyone who's too lame to know how to build just line operated unregulated DC psu shouldn't be anywhere near high current EHT or xrays! Sry to sound mean but like you say facts are facts and safety is more important than pampering egos!

Let me know how I can make myself useful?

JC Sry but that takes visiting thread more frequently than transient of Venus! So if you really want to help u can just read through main tutorial and addendum and catch grammar and w/w errors and like that

And I say you just don't or won't get it. The world at large doesn't work as you seem to think it does. Most people(you and HP not seemingly included) don't get to "set" their level of compensation for their work. Most only have two choices, (1) accept the prevailing wage(in my case the highest paid in the area), or, (2) don't have any income.

Shortbus All I was saying is I'm sorry if I insulted you cuz I didn't mean to! So anyhow, abt all the wage and price stuff, I totally understand! It's just that you and I have different perspectives cuz of different life experience so let's just bury hatchet and move on!

 

HP I totally hate to ask but if u can find time plz upload pics of the xfmrs that show better detail of core

I'll see what I can do -- No promises prior to Saturday...

Indeed! The 'PolyPhos' is the first iron-core 'High Frequency generator' I've encountered -- While I expect the principle of operation is indeed via some manner of 'flyback conversion', I concur with your observations (especially as regards the minuscule 'EHT' 'duty cycle' inherent to such topologies) -- Inasmuch as the lot did not include drivers (i.e. 'primary circuitry') it seems only Siemens knows (and they ain't talkin') -- While I must confess my temptation to merely purchase a complete PolyPhos 50 system that I might satisfy my curiosity - I've enough projects on for the nonce

HP Since you asked I say anyone who's too lame to know how to build just line operated unregulated DC psu shouldn't be anywhere near high current EHT or xrays! Sry to sound mean but like you say facts are facts and safety is more important than pampering egos!

Undiplomatic howbeit, IMO, accurate! For all that I feel provision of a schematic is 'in order', as it were?

Best regards
HP

HP that's just BOGUS! All I need is 4u to upload pics of the transforms in better lighting aeap! From the way ur carrying on you'd think I was asking for a kidney! HP seriously! I know ur vry busy cuz of supervising construction of Gen shack and all that! But I say u can spare like 5 minutes to just snap and upload!
Also if it's not asking totally too much do u think u can manage a pic of that toroidal line xfmr that's identical to the one I salvaged from Powervar conditioner?

 

For all that I feel provision of a schematic is 'in order', as it were?

HP so ur saying ppl who need a diagram just to connect a variac a stepdown xfmr and a few rectifiers and caps meet perquisites for the tutorials? Whatever!

 

HP when you get back plz post pics immediately! Cuz I prolly won't have a chance to be on here this weekend

 

HP?!

Did you mean prerequisites or do we all get auto-transformers and rectifiers for reading the tutorials?

Johnintx I meant prerequisites o/c but now that you mention it, maybe bribery to generate interest in tutorials isn't a bad idea at all?
