@shortbus - Seriously! I don't think anyone is 'looking down on you' (I'm certain none of us are) -- As for JC, while it's true that I'm financing his education - he's doing the difficult part via his diligent pursuit of his studies!:)
I'm sorry but as part of the "austerity crowd" when he called me out I had to respond. If your into 'financing education' PM me and we can set up the same type of arrangement for me. What I've got out of life I've worked for, I'll not let a 27 year old 'school boy' living off of someone insult me.

Re: Our 'heated' wage/price discussion - I don't understand how you and @#12 came by the notion that we were disparaging you?... On the contrary! I know I speak for @Aleph(0) and @Jazz2C when I state that I respect your skill, experience and recognize the difficulty of your work! Hence my assertion that you are under-compensated! - Which is not to gainsay your claim that "that's the way it is" - but, rather, to express my strongly held opinion that such is unjust - and that I would not and do not treat my employees in that fashion...
Not 'disparaging' but just out of touch with most people in the world. Look at what the majority of people make or live on in life. I'll bet there aren't to many members that have a "compound" and live in housekeepers or even house keepers of any sort. If you pay your 'employees' well and above scale you are certainly in the minority of employers. I don't think you have a good idea of how "the other half live". I'm very sure I could manage easily to live you 'three amigos' life, but don't think you could change places with me very easily or for very long.

If you three think of people with less money and knowledge than you have this should be discussed in PM's not in public forum.

@shortbus I really am making a genuine effort to bring these lessons/projects within reach of all genuinely interested parties regardless of 'socioeconomics' - hence my emphasis on DIY, non-standard component sourcing and 'enlisting' JC's assistance/advice in garnering input from a (hopefully) diverse sample of students..
That being the case, I implore you to please draw our attention to any unrealistic or otherwise unreasonable assumptions/expectations that we may have of our readers (Re: the tutorials, etc...) -- Please know that this is a genuine request -not confrontation- We need all the help we can get and it seems you've identified a potentially very serious problem! --- It's no exaggeration to state that this series is -far and away- the most difficult undertaking I've taken on by way of a presentation! --- The cognitive, intellectual, cultural and indeed socioeconomic 'breadth' of our 'target readership' represents a formidable challenge quite outside of my previous experience -- said onus being exacerbated -in no small measure- by the definite safety issues necessarily attendant to the subject matter.
You think your doing this using tools that most people can't get? Medical things that aren't available to the public? Emergency rooms won't even give you the hemostats they use on you when you get stitches because they are 'medical implements' but they through them away after use. I know because I've asked when being treated. So how are the ones outside of your sphere supposed to do it the way you will eventually publish? You can't go to the hardware store and buy retractors, speculums and the like.
 
I'll not let a 27 year old 'school boy' living off of someone insult me.
I'll let @Jazz2C speak for himself (I expect him to login again no later than this coming weekend) - that said, I very much doubt he was intentionally insulting you! -- As I saw/see it, his use of 'Austerity Crowd' was in response to your (and certain others') seeming 'objection' to my insistence upon paying what I consider fair 'wages' -- Stated otherwise (IMO) JC was not calling you 'mean' but, rather, 'overly forbearing'...

a 27 year old 'school boy' living off of someone
There really is much more to it than that!... But then it's hardly 'my place' to expand upon same...

I'm sorry but as part of the "austerity crowd" when he called me out I had to respond.
Understood...

you pay your 'employees' well and above scale you are certainly in the minority of employers.
Perhaps - howbeit I hardly see how such constitutes 'bad' practice:confused:

I'm very sure I could manage easily to live you 'three amigos' life, but don't think you could change places with me very easily or for very long.
:confused: @shortbus If your point is that abundance of financial wherewithal 'makes life easier' -- I wholeheartedly agree!... That said, I feel we are all of sensitive to and accommodative of readers/prospective readers struggling with limited means...

In the words of Messrs. Emerson, Lake and Palmer: "There might have been things I've missed - but don't be unkind - it don't mean I'm blind":oops:

If you three think of people with less money and knowledge than you have this should be discussed in PM's not in public forum.
I apologize that I don't understand the above quoted sentence (owing, perhaps, to an inadvertently omitted word?) -- In any event we have no 'problem' whatever with people struggling with limited financial resources! -- In point of fact we're attempting to reach out to and include them in this effort!:cool: Then too we expect that most interested readers will be 'less knowledgeable' than ourselves on much of the subject matter covered in the course of our series (hence their interest) -- what we (Spec. myself and especially @Aleph(0) ) have little patience with is willful ignorance! -- But then we've seen none of that among the AAC membership whatever!:)


Medical things that aren't available to the public
Please recall that your concerns in that regard were addressed HERE -- The principal 'takeaways' being:

1) Transfer, possession, etc of most medical devices/instruments is regulated/restricted only where said equipment is offered as or intended for medical application -- that said, I advise caution regarding devices likely to be deemed 'drug paraphernalia' in certain jurisdictions (e.g. syringes, hypodermic needles, etc...) 'caution' meaning staying abreast of local regulations and insistence upon conducting all such transactions conspicuously 'in plain sight', as it were!

2) The medical instruments are not required for completion of any project offered here (present or future) -- They are suggested merely as a 'source' of highly versatile, excellent quality and, ironically, often low cost alternatives to much lower quality consumer grade 'equivalents'...

Emergency rooms won't even give you the hemostats they use on you when you get stitches because they are 'medical implements' but they through them away after use.
The disposition of 'medical waste' Incl. 'spent' and decommissioned medical instruments (and, for that matter, excised tissues -- Aye! Aye! Aye! - What passes for 'souvenirs' with some peopleo_O:rolleyes:) is as per state and local 'health codes' as well as institutional policy -- generally speaking, healthcare facilities/institutions are poor sources in this regard - That said, 'Biomed' may be helpful with (sanitized) decommissioned devices/instruments...:)

So how are the ones outside of your sphere supposed to do it the way you will eventually publish?
Succinctly; Via certain medical/biomedical equipment suppliers, and, of course, Ebay and it's ilk -- Please refer to the post linked above for further detail/caveats...

And, again -- medical instruments are merely an option - not a requirement:cool:

Very best regards

HP I did it on less than my petty cash funds of $500 per mo! So $1000 will totally suffice with a broad margin for newbie mistakes:cool:
But then it seems you already possessed some of the materials and nearly all of the tools? -- Whereas we're bound to 'operate' under the assumption that each user must purchase all required tools and materials...

BTW
my petty cash funds of $500 per mo!
That's $1,500 short!:rolleyes: -- I hope you haven't 'taken up' gambling for stakes?!:mad::rolleyes:

It's looking like the number of enrollees will be limited only by the number of flybacks available! I've already found 23 eager high quality volunteers and I haven't really started looking yet!
In the (IMO unlikely) event that 'AC' LOPTs prove elusive, we'll need to locate a reliable source of same prior to 'going live' -- Again -as regards proofing/alpha testing- I can supply the LOPTs if necessary, howbeit, in the interests of project 'manageability', I suggest limiting 'enrollment' to 50 participants? -- but then that's your 'call' inasmuch as you're 'project coordinator':cool:

Ideally I want them to register b/c more interaction here translates to increased public exposure and PR for ur projects!:cool:
Agreed! That said I'll be pleased to meet them 'half way' (and then some) if it means getting this done!:)

...for ur projects!
--Emphasis Added--

That's OUR projects! -- Yourself included!:cool:

Yes! And culling prospective enrollees is my responsibility (my action) for which I'm answerable!
While indeed selection of the participants is part of your 'role' in this project -- Their 'latent proclivities', liability to impulse, etc aren't down to you...

HP I know you'd hold Personnel responsible for bad employees? What's the difference between their responsibilities and mine?
Merely that you are a friend and collaborator assisting me to select volunteers for a very low (in this case near zero) liability alpha-testing program -- as opposed to a team of professional staff tasked with CV/resume parsing, background checks and 'character evaluation' of candidates for security-critical positions...:)

Just so you totally believe that I'm in earnest that it's unnecessary!
You may rest assured that I have absolute faith in your sincerity!:)

Back at ya Sunday!
Many thanks!

Very best regards
HP:)

I'll let @Jazz2C speak for himself (I expect him to login again no later than this coming weekend) - that said, I very much doubt he was intentionally insulting you! -- As I saw/see it, his use of 'Austerity Crowd' was in response to your (and certain others') seeming 'objection' to my insistence upon paying what I consider fair 'wages' -- Stated otherwise (IMO) JC was not calling you 'mean' but, rather, 'overly forbearing'..
I was willing to not respond the first time he brought it up, and if you go back and read I didn't. You warned him about saying things like that, and he didn't heed your warning and had to bring it up again. I couldn't let it slide a second time. For someone of his age that doesn't seem to have to work and probably hasn't had a full time 8 hour a day job so far, to come out and say what he did just rankles my every fiber. I wear jeans that have holes in them from hard work, not because they are fashionable. I don't go on "pilgrimages" what ever that meant. While I'm more well of than many I know, I don't rub it in their faces. I live within my means, not within what some benefactor allows me to. So to call me the "austerity" guy, or imply there is something wrong with that, by someone that has life given to him on a silver platter, is whether intentional or not insulting being where it came from.

It's not the fact that you felt obliged to pay a fair wage to the 'scrappers', but the way you seemingly don't understand the way things work at a level below your lifestyle. Out of touch with the rest of the world. When you go to buy something in a store, do they pay you for buying that object? You were giving them something of value free and clear, that's how most things work in scrapping. The scraper gets his money/pay from selling it. It's not like paying someone to clean out your garage, this amount of value was a commodity to them, or at least that's how it has worked in my years of doing it.


:confused: @shortbus If your point is that abundance of financial wherewithal 'makes life easier' -- I wholeheartedly agree!... That said, I feel we are all of sensitive to and accommodative of readers/prospective readers struggling with limited means...
I don't at all look at this as putting you down for having wealth and me not having the same amount. But when you keep throwing out dollar numbers that most can't afford or justify for doing this project as just being, "in everyone's pocket change", you are, to my opinion out of touch again. You have said that if I remember correct, that a $20,000 scope is a mere pittance to you, but don't seem to know that, that is more than many make in most of a year. But in your reality it's just nothing, or again in my opinion that's how it sounds.

I apologize that I don't understand the above quoted sentence (owing, perhaps, to an inadvertently omitted word?) -- -
Your correct the sentence should have used the word TALK ABOUT not THINK.
"shortbus said:
If you three talk about people with less money and knowledge than you have this should be discussed in PM's not in public forum." Is what I meant to say. I some/most times tone my rants down before posting but missed that part.

2) The medical instruments are not required for completion of any project offered here (present or future) -- They are suggested merely as a 'source' of highly versatile, excellent quality and, ironically, often low cost alternatives to much lower quality consumer grade 'equivalents'...
And yet after 2+ years of this project with little real progress in content, how do you expect to find out from people that have skills and knowledge of tools beyond your scope expertise, if there are other means of doing what your attempting? What has been presented so far in this is, 'this is the way it needs to be done, using only these tools'. But on the other hand, you ask for input on it.

On the real project there has been not much progress into what is done, or even needs to happen, since the subject of tools was brought into it. And all of the interpersonal topics that should have been discussed in private not public. While I take responsibility for disrupting the thread, it has mostly been due to things that have been made public that should of been behind closed doors, between you, Aleph and now jazz.

@shortbus I truly feel you've got @Jazz2C 'all wrong' -- But then said misapprehension is entirely his fault owing to his failure to 'expand upon' remarks that might reasonably be expected to offend sans qualification... But really - he's hardly a 'deadbeat', 'freeloader', 'spoiled Millennial', etc... Quite in spite of my 'razzing' him Re: 'online gaming' and his faithful attendance of the Sturgis rally and Daytona Beach (i.e. 'spring break'), etc... He's a nice kid and a highly intelligent hard working (and, I might add, promising) student!:cool: -- Sadly, it seems his 'offhand' remarks have made a rather poor 'first impression' -- But then this is between you and him... (To wit: IMO @Jazz2C owes you an apology and an explanation!)

I don't at all look at this as putting you down for having wealth and me not having the same amount. But when you keep throwing out dollar numbers that most can't afford or justify for doing this project as just being, "in everyone's pocket change", you are, to my opinion out of touch again. You have said that if I remember correct, that a $20,000 scope is a mere pittance to you, but don't seem to know that, that is more than many make in most of a year.
And I maintain that $20k for combined TDO, SA, LA/PA functionality --in any case but especially in a product of a 'venerable' and highly reputable manufacturer-- is an outstanding value! -- Hey @shortbus? If you know of a better deal I've an open mind (sincerely)?:)

Please note that said equipment is neither required nor suggested Re: our projects (EHT and 'sensitive' equipment don't mix! -- double so in the hands of 'nubes'!:eek:)
(Sorry JC, but you had that coming!:p)


but don't seem to know that, that is more than many make in most of a year.
Come to that, I'm certain that you too are wealthier that most of the world's population! -- But then this line of discussion would seem moot inasmuch as the series does not require said equipment?:confused:

When you go to buy something in a store, do they pay you for buying that object?
But that's faulty parallelism isn't it? (No, I don't mean in the 'grammatical sense';)) -- To wit: I didn't pay them to buy the steel -- I [under]paid them to remove an appalling 'heap' of junk in a timely fashion!:rolleyes:

The scraper gets his money/pay from selling it.
What they choose to do with it post-removal is entirely their affair and in no way enters into my evaluation their service...

If you three talk about people with less money and knowledge than you have this should be discussed in PM's not in public forum."
I take it that by 'talk about' you mean speak disparagingly of?

@shortbus the only people we disparage are the 'willful ignorant' (and then only in the most general terms) - Please know that I am absolutely sincere in my assertion that I've not encountered that particular 'demographic' on this site's fora...:)

But to continue:
I would have thought that my blog alone offers ample testimony to the importance placed upon 'outreach' to interested parties struggling with limited resources!? -- As to 'lesser knowledge'? Again, it would seem to go without saying that most interested readers will be 'less knowledgeable' of a subject than the presenters thereof:confused:... It is our genuine desire to assist all interested readers' transcension of financial, cognitive and 'time allocation' obstacles (which being the veritable bane of 'independent study' for many)... Our approach is that of pure concept but with the 'hook' of 'hands on' 'labs'/interesting projects:cool: (as opposed to the all too common practice that has education confused with rote memorization, etc...:rolleyes:) While I've witnessed excellent results with said 'enhanced conceptual approach' over the years -- I'm bound to say development of effective presentation strategies of same to so large and varied an audience as we are now attempting to 'take on' has proved daunting to say the least! -- even so I've high hopes -- thanks to @Aleph(0)'s suggestion of the 'Alpha-testing' program and to @Jazz2C 's kind cooperation with same!:)

What has been presented so far in this is, 'this is the way it needs to be done, using only these tools'
When completed, the 'step' headings will list alternatives for all newly introduced instruments (where available/appropriate)...

how do you expect to find out from people that have skills and knowledge of tools beyond your scope expertise,
Well... For starters there's this :)
But on the other hand, you ask for input on it.
(Recall our productive discussion of calipers vs. micrometers?:))

Then too, I'm confident the 'Alpha Testing Project' will assist us to identify and address several additional 'problem areas':cool:

and yet after 2+ years of this project with little real progress in content,
On the real project there has been not much progress into what is done, or even needs to happen
Indeed, tutorial development seems to have assumed the caste of a swimming duck -- To wit: placid on the surface - but "goin' like mad" below the 'water line':D

But seriously - neither the 'Instrument Addendum' nor issues in regards to instrument selection had any bearing upon the tutorials' 'lapse into stasis' -- which being 90% down to interference by 'off-line life' and 10% down to the demands of determining --and researching the needs of-- our 'target audience'...

And all of the interpersonal topics that should have been discussed in private not public
But then, apart from the tutorial posts, this thread is not intended as instructional material!:eek: -- It is merely a 'work room'! - and, as such, tends to be rather 'messy' - But then it grants our readers (and other 'interested parties') an opportunity to 'get to know us', a 'platform' for feedback, and a resource for possible 'disambiguation'/clarification of tutorial text... --- It is neither expected nor recommended that anyone read the entire thread!o_O

While I take responsibility for disrupting the thread, it has mostly been due to things that have been made public that should of been behind closed doors, between you, Aleph and now jazz.
@shortbus you have not disrupted this thread - It was was placed in 'Off Topic' such that relaxed -even controversial- off-topic discussion would be appropriate... All we ask is that participants abstain from political/religious discussion and 'trolling' -- you have certainly not crossed either of those lines:)

As regards the 'personal content' - While markedly less than comfortable with such content myself -- it seems that such is 'business as usual' with members of @Aleph(0)'s and @Jazz2C's generation - Thus it is that common courtesy and gratitude for their significant contribution to this effort (to say nothing of recognition of the fact that said generation comprises the majority of our prospective readers) demands meeting them 'half way', as it were...

Very best regards

As part of the "austerity crowd" I was only stating facts of life for the majority of the people in this country and the world. Sure I would like more money to spend on 'hobbies', but the realities of life set in when you, own a house, pay property taxes, and other everyday expenses.

At 27 I had been working a full time 10 hour a day job, and working part time job 10-12 hours on Sat and Sun for 9 years, and continued way into my 40's. Didn't have a "benefactor" to help support me, and was independent enough not to seek one out. So I still stand by my words that you, Jazz2C, Hp and Aleph are the ones "out of touch" with the realities of life. It's great that Hp is able and willing to help 'support' you in your life style, but don't ever think you're living like the 'rest of the world', because you're not. Look down on me all you want but just hope and pray that you NEVER need to find yourself in the predicament that the rest of us live in, because you are sadly prepared for what I call "reality".
I was willing to not respond the first time he brought it up, and if you go back and read I didn't. You warned him about saying things like that, and he didn't heed your warning and had to bring it up again. I couldn't let it slide a second time.

So to call me the "austerity" guy, or imply there is something wrong with that, by someone that has life given to him on a silver platter, is whether intentional or not insulting being where it came from.
@shortbus Sorry man I didn't mean that as ridicule! It just seemed strange that some of you were sounding angry at Hp and A0 for arguing that you should be paid more!:confused: Where I grew up in central Minnesota there's a religious order that helps ppl out, you know stranded motorists and such. But if you want to pay them they get angry b/c "you aren't accepting their friendship in the spirit it's offered" based on their pledge of "Austerity". So seeing ppl angered that others think they deserve better pay reminded me of that. And you're right! If I had to walk a mile in your shoes I'd probably shrivel up and blow away after the first few steps!:oops: You and my father totally agree on that!:oops: He's pretty disgusted that I've been in college since graduating high school b/c of continuously changing my major. But It wasn't out of desire to be a "professional student" I was just trying to find myself. I know:oops: Hp says I'm like a character in a book by Shirley Jackson who said "I'm afraid of knowing what I really want" I don't know the context but that much fits me like a glove:oops: But now, thanks to Hp I'm totally committed to my present course of study so I guess it's better late than never!:cool:


Just to clear the air, I absolutely do NOT look down on you! I totally admire your hard work, your independance and your experience garnered skills! But I also agree with Hp and A0 that you're shamefully underpaid though no fault of your own!

OBTW I'm NOT related to Hp! So whatever else I am, I'm NOT a would be... Well, you knowo_O

Hp abt the testing program I have to interview a few more prospects and check out a supposed local source for AC CRT flybacks (as per your mantra "seeing is believing":cool:).

Right now It's looking like at least 30 totally reliable participants:) If all goes as expected it should jel by Tuesday:)

Until then I had to clear this up:eek:
That's $1,500 short!:rolleyes: -- I hope you haven't 'taken up' gambling for stakes?!:mad::rolleyes:
No no no Hp!:eek: It's nothing like that! Just payments on my new bike! With this plan I can have it totally paid off in three years!:)
 
Hp says I'm like a character in a book by Shirley Jackson who said "I'm afraid of knowing what I really want"
JC!o_O -- Indeed I do believe that 'fear of knowing what you really want [out of life]' is a major 'hurtle' for you -- but NOT for the reasons such was the case for said character!:eek::eek::eek: Perhaps a bit of research prior to publicly 'waxing introspective' is in order?;)

Excellent! -- Thank you!:)

No no no Hp!:eek: It's nothing like that! Just payments on my new bike! With this plan I can have it totally paid off in three years!:)
JC --- Please understand! This is not a 'lecture' -- Inasmuch as the motorcycle represents a genuine means of recreation for you - I have no problem 'there' whatever! -- I do, however, have serious concerns with your having limited your 'spending funds' to a mere $500 per month!:rolleyes: -- Sans 'short term rewards' (i.e. events/activities to 'look forward to') I see your studies slipping!:(:rolleyes: -- So... Here's the deal:

Option #1) I can purchase the bike for you outright (if you insist, you may repay me -interest free- following graduation - once having a 'decent' income)...

-- OR --

Option #2)
You may continue financing the machine and I'll merely increase your petty cash allowance such that your uncommitted funds once again stand at $2000 per month...

Note that option #1 obviates financing charges whereas option #2 may help 'bolster' your 'credit' -- the choice is yours howbeit please be advised that there's no third way!...K?
Be advised that I'm in no mood for an argument!

Very best regards -- and, again thanks!

Yo Hp!
So I found 43 peeps who expressed serious interest but only 31 that I absolutely trust to stick with it and give honest feedback. So 31 is the magic number!:cool: But that's not all! 6 ppl already completed the endpoint ground to floating secondary conversion and two more started but quit b/c they had the wrong type flybacks:rolleyes: So I took the liberty of getting both of them the right transformers ($36 apiece from the old Reese Targo shop) so basically you have 31 enrollees plus 2 quasi-autonomous learners plus 6 grads:D

So the only negative feedback from those eight "outlier" students (except for difficulty finding parts and such) is that most of them had trouble with broken ferrite cores during the disassembly phase despite using a heatgun like you described in the text. Also one guy fried his secondary in the process by overheating it:rolleyes: The five who broke their cores were able to totally repair them with HT epoxy like you said! And the dude who Saint Joanized his secondary got over it b/c he found out he had the wrong flyback after all!:D

On the positive side they like your "explicit, unambiguous text" and "intelligent no nonsense approach" (their words). When I told them that's in keeping with your philosophy of assuming ppl are at least as intelligent as yourself the consensus was that it showed and is a major part of getting and holding on to their interest in the courses and having confidence in your tuition!:cool: Hp don't be bugged abt the word "consensus"! It would have been unanimous but three already knew abt your anti-dumbdown policy from reading your posts abt it and they appreciate it as much as those who discovered it for themselves!:cool: also they totally dig the pics but some of them want them embedded to automatically display b/c the onsite viewer is glitchy in some browsers...
I'm going to talk to them on a more individual basis abt their entire experience but so far it's sounding awesome!:cool:

Some of the enrollees are asking me abt the brands and vintages of tvs with desirable flybacks? I know those antique RCA 21" roundies (Newvista color?) are a good source if you can find them b4 tv resurrectionists hoard them:mad: But iirc you said they were standard equipment in other tvs too?

BTW -- No promises yet but it's looking like I'll be sending some new AAC recruits your way after all!:)

Option #1) I can purchase the bike for you outright (if you insist, you may repay me -interest free- following graduation - once having a 'decent' income)...

Definitely option 2! Hp thanks so much! I wasn't going to say it but I was already getting totally depressed abt basically destroying 36 months of R&R time on an impulse:oops:

Good deal!:) -- How many LOPTs of the required style are available from said firm?

So the only negative feedback from those eight "outlier" students (except for difficulty finding parts and such) is that most of them had trouble with broken ferrite cores during the disassembly phase despite using a heatgun like you described in the text.
Indeed:( - The 'hysteresis heating' technique is the preferred method on a number of 'fronts' - unfortunately such requires 'putting the cart before the horse' via prerequisitory construction of driver circuitry...

Also one guy fried his secondary in the process by overheating it
Which being yet another liability of the 'hot air gun' approach...

Well hey! Sincere thanks! You've identified an area in requirement of some 'rethinking'!:oops::)

It would have been unanimous but three already knew abt your anti-dumbdown policy from reading your posts abt it and they appreciate it as much as those who discovered it for themselves!:cool:
Golly! That's nice to hear!:D:D:D

they totally dig the pics but some of them want them embedded to automatically display b/c the onsite viewer is glitchy in some browsers...
--Emphasis Added--

That's the plan when published (embedding the images makes for irksome editing due to 'loading delays', etc...) --- That said, for their convenience, I can post a 'copy' of 'the work in progress' whereon images are so embedded...:)

I'm going to talk to them on a more individual basis abt their entire experience but so far it's sounding awesome!:cool:
Excellent idea! -- Thanks!:)

Some of the enrollees are asking me abt the brands and vintages of tvs with desirable flybacks? I know those antique RCA 21" roundies (Newvista color?) are a good source if you can find them b4 tv resurrectionists hoard them:mad: But iirc you said they were standard equipment in other tvs too?
Indeed! Said receivers were manufactured in the 'interval' between the advent of CTV (and, hence, the requirement of higher second anode EMFs) and adoption of the practice whereby a relatively low EMF LOPT was followed by a 'multiplier' (typically a half-wave CW tripler ) --- I'll see what I can find out! --- @ian field - do you have any insight into this you wish to share?:cool:

BTW -- No promises yet but it's looking like I'll be sending some new AAC recruits your way after all!:)
That would be very nice! -- Nothing beats a fully interactive environment where instruction is concerned!

Definitely option 2! Hp thanks so much! I wasn't going to say it but I was already getting totally depressed abt basically destroying 36 months of R&R time on an impulse:oops:
I guessed as much (believe it or not I was once your age - away back in the Precambrian era!:eek:;)) -- BTW I feel you've made the best choice! A solid credit history/profile is as a character reference in many cases!

Very best regards
HP

How many LOPTs of the required style are available from said firm?
They have 100s of vintage flybacks but w/o specific numbers it's hard to go through the boxes to find the right types:(
As per your e I bought out their entire stock of all 54 "FLY-307s" so that covers the alpha project plus a posh snafu cushion!:D

Abt adding to your personal stock, I told them we guarantee to "out bid" all offers for flybacks with secondaries like the 307s so they're helping me find them! So no fear of a run! Anyway I'll expedite things as soon as you send me the numbers and EFT me the jack;) Based on an hour's more or less random search I'd say it's a 10% proposition so you're looking at easily 800 flybacks with the 35kv tire-form secondary:cool:

That said, for their convenience, I can post a 'copy' of 'the work in progress' whereon images are so embedded...:)
Please! ASAP! For now don't even bother finishing it! Plz just change the links to embedded pics in the latest draft! Right now a lot of ppl want to read it but they have problems with the links so I know you'll want to keep their interest while the iron is hot.:cool:

Knowing just the manufacturers and years for color tvs with single high vacuum rectifiers and 20" or larger crts would be awesome b/c the replacement "FLY" numbers are listed in their old Stancor & Thordarson catalogs.

If you have not already done so please take physical possession ASAP!

Indeed it does! -- To that end, supplying the entire project with the same 'model' was more than I'd hoped for! -- Many thanks!:)

Good deal! The funds should be 'on account' no later than Wednesday (rackin frackin holiday!) -- I'm still working on the year range for 'full voltage' AC flybacks...

you're looking at easily 800 flybacks with the 35kv tire-form secondary:cool:
Excellent! But please! Under no circumstances ship 'my' purchase via courier! I'll send 'CB' for them! --- Because, ya see... LOPTS just plain work better when kept dry and undamaged!o_O

I'll get to it by Wednesday at the latest!:) (PS mixing metaphors is one thing -- but 'fragmenting' them?...;))

Thanks so much!:)
Thank you!:)

It's a fait accompli:D

I'm happy you feel that way! I know it's a tradeoff between easy replacement of likely to be damaged parts and assessment of the course's applicability to a diverse range of flybacks. Glad we're together on this one!

Wednesday is awesome! They're closed until Tuesday anyway.

LOPTS just plain work better when kept dry and undamaged!o_O
I heard that rumor too!:D

I'll get to it by Wednesday at the latest!:)
No worries! I can spin doctor it that long!:D

Hp plz don't take this the wrong way but I suggest you test out A0's idea's for clamping the screen to the Faraday shield frame and talk abt it here ASAP! She's back today and I don't have to tell you abt her post convention affective disorder!:p

HP not to throw dewar of ln2 on this but I say knowing how much they're willing to pay to follow tutorials is totally critical factor too! Also can _beneficiaries_ be reliable honest reviewers? I don't think so:rolleyes:

HP yeah! Like he said:rolleyes:;)

JC I totally own being drunken slut on conventions so what's your excuse for exactly same conduct at Sturgis?:p
So HP keeps saying we'll outgrow it but news makes me worried we'll never have the chance:(

Well indeed it is! - At this point, however, my focus is upon identification and amendment of 'problem areas' - It would seem all of unreasonable and unrealistic to expect financial outlay in addition to the not inconsiderable investment of time and 'agro' they've kindly volunteered to an, as of yet, 'unproven' program -- Please bear in mind that even as little as $1k represents significant expense to some students...

Also can _benefactors_ be reliable honest reviewers? I don't think so:rolleyes:
---Emphasis Added---
The following assumes you intended 'beneficiaries' with the above emphasized text...

They aren't beneficiaries! -- They are volunteers! -- Inasmuch as a functioning EHT PSU (once successfully constructed) represents the sole compensation for their time and effort, they have every motivation to report difficulty and no reason whatever to 'humour' me!

It works great and most of the images have been captured -- patience!:)

Exactly! -- thanks for understanding!:cool:

JC I totally own being drunken slut on conventions so what's your excuse for exactly same conduct at Sturgis?:p
While it is obvious that your intent (with the above quoted question) is that of decrying disparate (CIP gender specific) standards of conduct -- it is equally clear (based upon past remarks) that you are likewise ashamed of your behaviour in said regard -- hence my suggestion that a gram of moderation over-equals several solar masses of self recrimination/denigration!:rolleyes:
To paraphrase your own words: "calling something stupid makes it even more stupid because it means you know better" -- Got it?:cool:

So HP keeps saying we'll outgrow it but news makes me worried we'll never have the chance:(
Hey! What's with stealing my generation's excuses!:mad::oops::p

Very best regards
HP:)
 
HP I say u can clamp screen to frame with just other pieces of stock facing toward frame with offset so screen is pinched between frame and stock pieces along two lines like in drawing below! Sry for lame drawing so ur right abt MS paint:mad:!

So black _Us_ are cross section of frame and stock piece and bluish line is screen:)
Yet another excellent suggestion from 'The Prodigal Aleph':)

Please be advised that what this (quick and dirty) demo version lacks in the way of 'pulchritude' is more than compensated by ruggedness and function...:cool:

Below pictured are the mesh, frame and 'clamps' (note that although I 'cobbled' the frame of pilaster stock, flat corner braces and solder - Fabrication via resistance welding is strongly recommended!


Shield assembly prior to cosmetic improvement


Appearance of front panel prior to shield installation.


Appearance of front panel ('raw' shield installed)


Apearance of installed shield following modest cosmetic improvement


Best regards

The same as yours, A0! Being drunk! After that the rest is basically predestined:oops:

I know, Hp (and A0). But Hp in your words "youth is best enjoyed when young" so what's to do?;)

Hp it's for sure Andropov and Chernenko and those guys were way more formidable foes than that spoiled fatboy with his poorly designed "bottle rockets" and wussy fission warheads! But I think @Aleph(0) is talking abt the whole graveyard spiral our culture is in! I mean all the factions, all the us and them!:( Hp plz remember that as children of the 90's and 00's the only credible threats to NA soil A0 and I saw while growing up was from terrorism which is pretty minor league compared to direct strikes from a foreign military!

The Faraday cage is awesome! I also like how it's secured by a single post for easy installation and removal!:cool:

Hp I got ur blurb Re: ur technique for grounding Al tape w/wraparound tabs but I don't understand the necessity? I dig your point that a strip taped to a conductive substrate is basically a floating capacitor plate b/c the adhesive insulates it from the substrate but why is that a problem?

Yo @Aleph(0)! Welcome back! Like Hp says "things get mighty dull around here w/o you, gal!":D
