HP Tnx but sry I didn't think of it sooner cuz I didn't know some dark screens are made out of anodized Al wire instead like polymer fiber or like that! So discovery was a happy accident:)!
You guys do know anodized aluminum is non conductive don't you? You will need to sand the anodized layer off to connect it to ground in your Faraday cage.

"An anodized surface is aluminum oxide surface, Gary; aluminum oxide is non-conductive, and anodizing is often selected because it is non-conductive, so an conductive anodize finish sounds like an oxymoron to me."
From, https://www.finishing.com/72/97.shtml There are many more saying the same thing on Google.

Absolutely! -- The passivation cladding will be removed at the edges where clamped by the (metallic) frame -- FWIW I plan on 'uping' images of the frame/mesh assembly as soon as I get 'round to assembling same:cool:

Many thanks for your interest!

Best regards

HP I say for frame you could use those steel strips which are abt 15mm wide which are like mounting rails for light duty cantilevered shelving (sry cuz I don't know what they're called)?

OBTW JC says he'll be totally back to routine by Saturday so he says to expect his post then:cool:

Hey @Aleph(0) - Thanks! -- I'm familiar with the material you're referring to and will check it out ASAP!:)

OBTW JC says he'll be totally back to routine by Saturday so he says to expect his post then:cool:
I'll believe it when I see it!:rolleyes:

Best regards

So... I've constructed a frame of, as you suggest, shelf pilaster stock with good results:) -- I'll 'work out' a means of 'aesthetically' clamping the mesh to same at my nearest 'convenience' -- thence 'up' images of the assembly!

Very best regards and many thanks for yet another excellent suggestion!:cool:

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:)

I believe it will work!:cool: -- Tho' it seems it will require drilling boltholes (7/64" for #4 machine screws) inasmuch as use of the pre-exsisting 'slots' allows much too much migration of the clamps...

'Please stay tuned':)

Best regards and again, many thanks!

And so it comes to pass!:cool:

please try to bring JC on board! -- His input is especially valuable at this juncture inasmuch as he and many of his associates represent our 'target demographic' as it were
Hp I'd be pleased to help in any way I can! Please tell me what I can do?

HP Getting JC on here isn't a problem but I say getting objective opinions from him is just impossible cuz of his affection for you:rolleyes:
That's all F'd up Aleph! My "affection" for Hp is one reason she can absolutely rely on my honesty!

@HP Just looking at your blog, your diy HV meter project looks awesome!

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:rolleyes::(
You got it! Furthermore your chosen approach takes advantage of the interactive nature of fora b/c you can tailor the level of specificity on an ongoing basis based on feedback.
 
Hp I'd be pleased to help in any way I can! Please tell me what I can do?

Thanks, JC!

For starters, please determine the number of personal associates (from among your 'social peers') who you feel would be genuinely interested in 'alpha testing' our tutorials --provided all materials (and/or funds for purchase thereof) are provided gratis and with no obligation of any kind-- All participants would have full owenership of their projects and receive perpetual 'customer service' (i.e. replacement parts, troubleshooting assistance, etc...) free of charge...

Inasmuch as 'ease of materials availability' should properly be part of the 'test', I prefer to send you the funds (as opposed to the materials) for distribution to 'good prospects' (i.e. individuals having genuine interest and at least a couple of hours per week to dedicate to the project{s})

I estimate that $1k per participant should 'cover' the LOPT Preparation 'phase' of the project? -- Does such represent a realistic figure to you?

Your 'duties' would include coordination of the testing program, materials/funds 'logistics', forwarding of the participant's questions/comments and encouraging them to register with AAC such that they might directly participate in tutorial development:)

Please know that, while I expect you to at least cursorily 'vet' the 'prospects', you would not be held responsible for 'deadbeat testers' in any way! - Students will be students:rolleyes: - That said, any who choose to 'party' with their materials allowance would need to be very convincing should they desire a 'second chance' as a 'tester':rolleyes:

Of course you would be compensated for your efforts!:cool:

Please let me know ASAP:)

Very best regards
HP

Sweet! I can grantee you five right now and that's just for starters! I'll have a definite number next weekend.

If anything it's a high figure!:cool: Finding AC flybacks sounds tough though. Lemme scout that one out and let you know.

You can rely on me no matter what Hp! But I'll need specifics b4 we get rolling on this:cool:

encouraging them to register with AAC such that they might directly participate in tutorial development:)
Hp that's real tough b/c the registration process asks for too much personal info:( I've had this out with A0! It must have changed since you and she joined b/c "first name" and "last name" were required when I registered and the ppl I know who follow your posts don't want to register with bogus names as they do on Facebook b/c it risks having their accounts closed and that would totally suck if it happened after they became invested in this community!
FYI I registered with my real last name b/c I wanted to count on access my acct but I've got to admit it creeps me out! Nothing against AAC b/c they have a proven track record but nothing stored on the web is ever totally safe from cyber criminals! With that in mind there's absolutely no reason to require real names for access to these fora b/c all advice is at the reader's risk and the poster's responsibility!
So I regret that it limits interactive feedback to those few intrepid souls who are ok with registering with their real info or risking acct termination with pseudonyms but a ray of sunshine lies in the fact that all pics linked from your blog display normally to guests!:) But anyway, there are more than ten ppl I know personally who follow your and a0's posts religiously! I promise to twist their arms to register but I can't sweep privacy issues under the rug in good conscience and I know you wouldn't want me to!

That said, any who choose to 'party' with their materials allowance would need to be very convincing should they desire a 'second chance' as a 'tester':rolleyes:
Hp @Aleph(0) is right abt your being too nice sometimes! That sort of ingratitude doesn't deserve a second chance! Really! What they'd need is euphemistically known as an "attitude adjustment"!:mad:

Please know that, while I expect you to at least cursorily 'vet' the 'prospects', you would not be held responsible for 'deadbeat testers' in any way!
Hp I appreciate that, tnx! But I'd hold myself responsible b/c it's not too much to ask that I choose ppl who don't waste your time and money!

Of course you would be compensated for your efforts!:cool:
HP that's totally unnecessary! I'm happy to help! Caution! If you bring it up again I'll get you in deep doo-doo with The Austerity Crowd on here by telling everyone how much you already give me each month for school expenses and what you call "petty" cash!;) Hp I help you because it's what I want to do more than anything else! But if you need a non-sentimental reason you may call it gratitude but you know there's way more to it than that!:cool:

Please be certain! a high estimate is desirable -- whereas even slight insufficiency is sure to slow the alpha-testing process and annoy/discourage participants...

How and if they register is entirely their affair! -- That said, inasmuch as AAC (i.e. EEtech) provides the hosting and, as such, effectively serves as our gratis 'publisher' - I request that you please strongly encourage the unregistered users to enable and 'click on' ads! -- As I see it, such amounts to 'paying the rent'!

all pics linked from your blog display normally to guests!:)
The fact that AAC offers a 'viewable by all visitors' option for blog entries is yet another reason to patronize their sponsors!:)

Hp @Aleph(0) is right abt your being too nice sometimes! That sort of ingratitude doesn't deserve a second chance! Really! What they'd need is euphemistically known as an "attitude adjustment"!:mad:
Deadbeats and 'leakers' are a 'permanent fixture' of 'the human experience':rolleyes: -- No need to take 'matters' so personally!

Hp I appreciate that, tnx! But I'd hold myself responsible b/c it's not too much to ask that I choose ppl who don't waste your time and money!
You are not responsible for anyone's actions but your own -- Nuff said!

HP that's totally unnecessary! I'm happy to help!
Please don't rekindle that bicker!:rolleyes::rolleyes::rolleyes: -- The issue is nonnegotiable! -- To wit: If you refuse to accept compensation the deal's off ! -- Topic closed!:mad:

Caution! If you bring it up again I'll get you in deep doo-doo with The Austerity Crowd on here by telling everyone how much you already give me each month for school expenses and what you call "petty" cash!;)
I very much doubt that I could be in anymore 'trouble' with --or more misunderstood by-- said 'crowd' than I am at present:( -- Hence you may consider your bluff 'called'!:rolleyes:;)

Looking forward to 'hearing' from you next weekend!:)

Very best regards
HP:)

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:

Should there be difficulty I can supply the LOPTs -- That said, assessment of the ease of independent 'sourceability' of said component is 'part' of the 'test'...
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! HP It pleases me to discover that you have a lot of avid readers since I showed them the thread abt a year ago!:)

I agree! I'll make sure everyone understands that! Ideally I want them to register b/c more interaction here translates to increased public exposure and PR for ur projects!:cool:

You are not responsible for anyone's actions but your own -- Nuff said!
Yes! And culling prospective enrollees is my responsibility (my action) for which I'm answerable! HP I know you'd hold Personnel responsible for bad employees? What's the difference between their responsibilities and mine?

The issue is nonnegotiable! -- To wit: If you refuse to accept compensation the deal's off ! -- Topic closed!:mad:
Ok! Pay me whatever you think it's worth if you insist! Just so you totally believe that I'm in earnest that it's unnecessary! Hp what bicker are you talking abt? If you mean your arguments with the ppl I call "The Austerity Crowd" don't sweat it! As long as I'm the recipient, overcompensation is no sin in my religion!:cool:

I very much doubt that I could be in anymore 'trouble' with --or more misunderstood by-- said 'crowd' than I am at present:(
Yeah I read that section and I don't get it either:confused: Ur right abt it being a misunderstanding b/c you were advocating higher wages and they were arguing from the POV of labor so I don't know what their problem was? Maybe they were telling you it's even worse than you think?

HP I almost hate to say it but I'm starting to think JC's feelings for you aren't just passing fancy but the real thing:(:rolleyes:!
It's about time, @Aleph(0)! It's nice to know you finally accept that I'm past the schoolboy crush stage at almost 27!:rolleyes:

BTW where is A0? I can't reach her by text or email either?:confused: I know she flew some ppl down to Kentucky for the eclipse but I expected her back by now? OMG! Is she "larking about" again?:p

Back at ya Sunday!

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".

Uncalled for rant @shortbus

If we're comparing, you being born with a plastic spoon in your mouth are better off and live in a fantasy world when juxtaposed against some in society. Let your petty behavior stop.

At ten per hour, that grand is a hundred hours. Look at her requisites. If you can do it cheaper, offer your services, assuming you can meet the prerequisites.

@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!:)

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...

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.
---Emphasis Added---

@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...

So I still stand by my words that you, Jazz2C, Hp and Aleph are the ones "out of touch" with the realities of life.
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...

With utmost sincerity and very best regards
HP

For my part I feel this entire matter is issue of an unfortunate misunderstanding:(

Initially, my point was merely by way of expressing my regret (and, frankly, embarrassment) at having under-compensated the salvage operators -- When @shortbus and @#12 stated that the scrap value alone represented a multiple of their wages I expressed my sincere opinion that they too were under-compensated (IMO a diddle is a diddle -- 'standard practice' not withstanding) -- That my esteem of their work exceeds that of their employers' is somehow offensive utterly escapes me:confused:

Best regards

Hey JC! -- Thanks for your response! -- Please expect my response later today/early tomorrow...

OBTW
BTW where is A0? I can't reach her by text or email either?:confused: I know she flew some ppl down to Kentucky for the eclipse but I expected her back by now? OMG! Is she "larking about" again?:p
It's hard to say whether she's 'hard at work' or 'hardly working';) howbeit I can tell you that she's in Amsterdam through the end of the month (she returns Sat Sep 2) --- As per her security obsess... Ahem... policy she's using a shiny new 'clean' phone and notebook -- I've just sent her contact info to your home email addy (@ 1:50 PM CDT)

Very best regards and, again, many thanks!

HP,

I applaud your efforts. Your desire to make an easily understood tutorial is quite a challenge. It's been said, and I'm sure there are statistics to back it up, that it takes four hours to prepare for a one hour class. That assumes one has mastered the topic.

I'll bet you and @Aleph(0) each have over 100 hours in this effort.

I like the fact you have enlisted your target audience as proof readers and testers to clear up any misunderstandings that can arise in this high potential project. You deserve all the accolades you receive and little of the criticism.

Keep up the good work,
