EHT power supply design and construction

All I did was complain that cooling your heels on the _trades_ was distracting you from tutorial
Not quite! -- What you did was to, once again, compromise my on-line anonymity! (IMO by design!) -- @Aleph(0) I'm bound to say that, for one who (quite understandably) despises all forms of collectivism and idolatry, your demonstrated disdain for privacy is nothing short of bizarre!:confused::rolleyes:

I think you owe me apology too?
You think so, huh?:rolleyes: -- To be clear: The nature of your 'very important' junkets is not the problem! Your incessant disregard of my privacy and unfounded accusations of laxity, however, are! --- You want 'sorry'? -- Well... there's plenty of that to be had in your distaste for 'your own medicine'...

HP I owe you apology
@Aleph(0) -- Know that your 'recidivism' in this regard does not brook confidence in your sincerity!:rolleyes:


HP I am delighted to help with tutorials but I need specific idea of what to do?
In addition to proofreading and 'alpha testing' I feel content contribution isn't asking too much? --- As Regards your 'connectivity troubles', you may compose it locally (via, for instance, 'Word') then 'copy and paste'...:cool:

But for the nonce -- please expand upon this:

HP I can tell installment is still at formative stage so nothing to comment on right now except to say that specialized instruments can be confusing to unfamiliar ppl, just saying.
--Emphasis added--

Best regards
HP

HP Ok fine! I apologize and you refuse to so now we move on:rolleyes:!
But for the nonce -- please expand upon this:
I'm saying some ppl maybe confused about curette?

HP you worried about privacy so I'm telling you that in some chat rooms someone using your exact screen name and writing style is signing posts with first name which is like masculine version of yours and a totally bogus last name initial. I emailed link so you can check it out.
 
HP Ok fine! I apologize and you refuse to...
You and you alone own your decision to apologize! --- Even as I own mine to stand behind my grievance...

so now we move on:rolleyes:!
Good deal!:cool:

I'm saying some ppl maybe confused about curette?
Really?:confused: -- I can but hope less so than am I by your penchant for ambiguity! (CIP - what part of "curette" mightn't they understand?:confused::confused::confused:) Seriously, as you yourself have stated, observance of some measure of scope is required are we to accomplish anything here! -- I can hardly be expected to digress into a primer upon basic instruments!? --- That said, I expressly stipulated type, tip configuration and size...
Perhaps your concern is that the instrument in question may be associated with a politically/'religiously' contentious procedure? -- Well, as you know, such is far from its exclusive (or even common) application!:rolleyes: -- Anyway - my suggestion (i.e. removal of epoxy from a ferrite form) seems rather unlikely to raise anyone to radicalism!:rolleyes:

HP you worried about privacy so I'm telling you that in some chat rooms someone using your exact screen name and writing style is signing posts with first name which is like masculine version of yours and a totally bogus last name initial. I emailed link so you can check it out.
I received your Email message -- all's cool! As you may have guessed, the 'posters' in question were indeed myself under a pseudonym -- Know also that there's no need for 'panic' should you see posts (on other sites/lists) bearing 'my' username while clearly varying from my literary style - as you may know, I (long ago) 'gifted' two 'users' to that certain 'gentleman' to whose defense you are so keen to run...:rolleyes:

Now perhaps you'll explain your rationale back of publicly alerting me to a potential security issue? --- Could it be that you wish your 'fan club' to see your 'high mindedness' in the face of my 'bitchy invidiousness'???:rolleyes:

Patiently awaiting a return to constructive dialog...

And now we return to the on going story of, "Days of our EHT power supply".........

:p:D
I'm bound to say that, among other considerations, it was apprehension of just such "soap-operatics" that prompted my request that this thread be transferred to OT:rolleyes::D --- That said, please rest assured there will be no such off-topic nonsense on 'Projects'!:):):)

Best regards

What I do in public is on public record so its like stronger commitment to sincerity to show YOU I care!

Perhaps your concern is that the instrument in question may be associated with a politically/'religiously' contentious procedure?
Not really cuz if they're savvy enough to think of that they're also with it enough to know better:cool:!
I was just thinking surgical instruments maybe beyond purview of electronics cuz different disciplines. HP I know how you say about _interdisciplinary parallelism_ and about overlapping of mainstream professions like electronics and healthcare but some ppl won't know what is a curette and that's just another level of intimidation for newbies.

Seriously, as you yourself have stated, observance of some measure of scope is required are we to accomplish anything here!
HP I say insisting to play your long suit can be like selling horse to buy plow! Now just chill cuz I'm saying mixed metaphors are better weakness than mixed drinks:p

HP I am saying thanks cuz you are doing more and more on tutorial! Is coming together very nicely:)!
HP plz explain what you meant in E about using more precice _terms of relative reference_:confused:? I think descriptions are perfect so maybe not mend what's not broken? Anyhow I'm so looking forward to moving on to drivers:)! See you soon! Only three weeks to go:D!

Um... Whatever:confused::confused::confused:

Agreed!:):cool:

First off, curettes are hardly obscure:rolleyes: -- Secondly, anyone too lazy or 'dim' to type a few characters into a search engine prompt then press 'enter' is a bad risk for experimentation with devices affecting electrical hazards commensurate with those of MOTs!:eek::rolleyes: -- There are just so many hours on the clock/pages on the calendar! - Are these articles ever to be completed, assumption of some competence/life experience/resourcefulness on the part of the reader is required!
HP I say insisting to play your long suit can be like selling horse to buy plow!
It beats attempting to sell a 'Smart Phone' to an Old Order Anabaptist!:p:D
HP I am saying thanks cuz you are doing more and more on tutorial! Is coming together very nicely:)!
Many sincere thanks! -- at this point I need all the encouragement I can garner!:):):)
HP plz explain what you meant in E about using more precice _terms of relative reference_:confused:?
For example: Inasmuch as the geometry of the EHT winding assembly is that of a disk (in addition to that of a form symmetrical about an infinite number of midlines) I prefer "central/peripheral" to "medial/lateral" or "proximal/distal" as regards relative reference in the plane of the 'disk'... -- 'Tweaking' of such nuances to follow completion and incorporation of the 'disassembly' installment:)
Anyhow I'm so looking forward to moving on to drivers:)
So am I!:D

All the best
HP:)

Many, many thanks for the feedback!:):):)
Post #330, step4, B...typographical error. "is" = "if"
Are you referring to this sentence? (Step 4 Precaution B)
B) While debriding residue from the 'medial gap' following removal of the Aux Shell - great care must be exercised is damage to the medial layer{s} of the EHT winding to be avoided!
I must confess to finding no error (in the above):confused: -- but then perhaps I've been gazing at the screen too long:eek::eek::eek: ---Please elucidate:)

EDIT: If the above is indeed the sentence in question: "is damage to be avoided" seemed clearer than: "if damage is to be avoided" --- Thoughts?

Please be consistent in labeling this as "cpvc". Some of us know the difference.
Thank you! I've now corrected that error and searched the entire post against repetitions of same!:):):)

Again, many thanks! Please keep the feedback coming!

Very best regards

"If damage is to be avoided" would be the way I phrase this. I guess it's a cultural difference. (Divided by a single language:D) When I read it slowly, I understand your intent, and it is pronounced with a degree of certainty not afforded by that to which I am accustomed. It's just that this usage is strange to me. If British people breeze through that sentence, comprehending in a single pass, then let it be.

HP Ok! Everything's alright about tools but I say you should suggest alternatives for ones that are less common for just electronics use. Now cuz main advantage of curette is that it can peel glue w/o writing metal traces cuz it's harder than ferrite. To be safe you can tell them to use non metallic scraper if they don't have hard stainless instruments ok?

HP I'm saying this on public forum cuz JC wanted out in open like this cuz he wants to join in on thread but he's worrying that he might be on bad standings with you:(! HP I'm not trying to start argument but I think you were too like you say frosty to him! He learning math for 2 years from you and you said he is good student but last night he was grown man crying his eyes out to me cuz he expressed his feelings to you and you couldn't care less:(! He poured his heart out to you and you were telling him he needed to get over his fancies and concentrate on his studies! HP I say you weren't trying to be cruel but you couldn't have been colder hearted if you studied on it:(! So now he wants to know if he's welcome here on thread cuz he's afraid you'll think he being like pest or stalker or something. HP I'm not siding against you but every time this sort of thing happens you aren't very compassionate about it:rolleyes:! HP he told me that he told you he knew it was unrealistic of him and he wasn't asking anything from you that he just wanted you to know! HP I'm asking was that so bad? You always say courtesy costs nothing so why are you so sparing with it when ppl need it most? Anyhow like I said I'm not taking sides but I promised him I'd post about this so he can know.

Now let me say that I'm very happy about progress on tutorial:)!

Will do!:)

HP I'm saying this on public forum cuz JC wanted out in open like this cuz he wants to join in on thread
As far as I'm concerned he (and, for that matter, anyone) is more than welcome here so long as genuine interest (or even vague curiosity) in the topic{s} is manifest!:):):)

HP I'm not trying to start argument but I think you were too like you say frosty to him!
So, in your assay, honesty/directness ='frostiness'???:confused:

you said he is good student
And indeed he is!:) - He's gone from abject inability to re-arrange linear expressions to Calculus II in slightly over one year! --- Which being especially noteworthy inasmuch as I am far from an ideal instructor:oops:...

but last night he was grown man crying his eyes out
1) I very much doubt that!
2) True or not I doubt he wished you to publicly post that!:eek::rolleyes::D
3) At 25 YOA it seems his emotional maturation is yet a work in progress --- Nothing personal! - 'tis sadly a 'condition' endemic to his generation!:rolleyes:

He poured his heart out to you and you were telling him he needed to get over his fancies and concentrate on his studies!
You may award him a 'gold star' for honesty!:D -- To wit: such precisely jibes with my recollection of the matter!:cool:

HP I say you weren't trying to be cruel but you couldn't have been colder hearted if you studied on it:(
And again, you align honesty with low temperature?:confused: -- Must be that 8 Oz of LN2 I start each day with!;););)

So now he wants to know if he's welcome here on thread cuz he's afraid you'll think he being like pest or stalker or something.
That's just silly! First off let's get our 'leaglease' straight: A 'stalker' is one who is legitimately perceived as a physical (i.e. violent) threat to the 'victim' or his/her family -- By no stretch of logic does 'JC' fall under that category! --- As an aside, fashionable as it has become, I do not believe in burdening law enforcement with personal problems!:rolleyes::rolleyes::rolleyes:

Again, he's both welcome and, indeed, encouraged, to participate here so long as he adheres to topic!

HP I'm not siding against you but every time this sort of thing happens you aren't very compassionate about it:rolleyes:
"This sort of thing" (Re: various individuals) happens far too often!:mad: --- Being the object of infatuation is merely annoying -- Idolatry, on the other hand, is unendurable!:rolleyes::rolleyes::rolleyes:

HP he told me that he told you he knew it was unrealistic of him and he wasn't asking anything from you that he just wanted you to know!
Indeed! His conduct was that of a perfect Gent! --- That said, his motives in conferring admittedly useless information escapes me:confused:

You always say courtesy costs nothing so why are you so sparing with it when ppl need it most?
I recall no lack of courtesy on my part:confused: --- Moreover it is my observation that people require honesty far more than courtesy!

Why he 'cries' on your shoulder and, most perplexingly, why he wanted this discussed in public is utterly beyond me! --- How truly the 'Facebook generation' lacks the merest concept of privacy!:confused::rolleyes:

Anyway, I'll be 'forging ahead' with the tutorial --- Please keep the feedback coming!:):):)

All the best
HP

I want to take core from old tv dougnut wound flybacks without damage the winding but they usually break!:( Does anyone know the ways to this?:D
Look for ones with a spring wire clip - they're less likely to be glued.

If the windings are to be discarded - you can sometimes loosen the glued ones in the microwave. The ferrite is very lossy at microwaves, so it only needs a few seconds.

Aye! Bewared, however, that said method not uncommonly leads to 'hot-spots' (with subsequent breakage or permanent shift of magnetic properties) and, in my experience, destructive arcing!:eek::eek::eek:

Inductive heating (via a loaded driver) -- or the solvent/heatgun technique described in the tutorial require more patience - howbeit said 'virtue' is, in this case, amply rewarded!:cool::cool::cool:
