I blame myself, I should never have pointed edison at the relevant patent.

Actually Verbatim... you are just as off topic as you claim others to be! You've proven yourself to

be a very intelligent, off-the-wall person. Do you honestly think people give a shit if you put them

on your foe list?

Soon everyone here will be on your foe list, in which case, you can just keep on talking to

yourself. What a shame... you could have been a valuable asset to this forum.

He is NOT posting pure bull shit... no one is going to "come to harm" because of what he's posted!

He simply doesn't know how to conduct himself and, as said earlier, it's a shame.

loki is a "self appointed technical expert" here and feels threatened by you verbatim. as you have found out it doesnt take much to be technical here his closest competition is the troll who was tosses out of the sleepyhead development by jedimark who used to defend him for unknown reasons.

verbatim i like your style and your contribution is long over due here. quote this post or it will be deleted by the one of the many sleepless trolls who to me are pure entertainment. please dont take any of them serious, i think their therapy has not been optimized and may never be. when they start deleting your posts contact johnny goodman who graciously provides this forum. i think he realizes it would cost a small fortune to have moderators here and just stifles information sharing, but this rudeness also does.

fwiw - mr goodman has had run ins with resmed before for hosting an auction site where used resmed and other equipment was sold

the many trolls here have run pugsy and many, many others off before, pugsy came back bless her heart but most others are gone forever or just read for the entertainment value. oh den is another who got fed up, left but also returned.

i understand your circuit and have to think even the likes of loki would put a meter on any new device before connecting it to even a spare test cpap, but hey i could be wrong.

keep up the good work i will be silently reading and watching "quote this"

edit: i am surprised by lucyhere who normally will defend people but for some reason has joined in on this gang style newbie flogging. for bs and the others it is just the normal everyday nonsense when someone new shows up

i am starting to think the internet is just a collection of angry unhappy people who dont get enough attention at home so get online and are happy with negative attention. so when angry unhappy people dont get enough sleep this is what the net result is.
i could give you a list on names of the idiots here but it seems they will all self identify

That goal of understanding is valid, whether or not anyone actually builds the circuit.
I have absolutely nothing against your building and testing this gadget. I hope you go for it! Please build it, test it out, run it for a while on a few machines and report back.

But what you've done is to present someone else's work, ranted at great length, alienated everyone on the site, but actually produced nothing!
verbatim wrote: What is your argument against trying to UNDERSTAND how the ResMed proprietary circuit works?

You might be skeptical of its merits were it to be built (and you should be), and you might want to see concrete tests and proof of feasibility before you, yourself, would build one; but you are not "afraid" of understanding a simple diagram, are you?
Trust me, I'm just about the most curious person you'll ever meet. When if you do really figure it out I'd like to see it, because I am truly curious why Resmed made this design decision. But you've produced a few hundred words of interesting stuff, and many thousands of on why we MUST be supportive of this effort, and many thousands more words on why everyone who doesn't agree with you is an idiot. Not a particularly compelling argument. If this was something the actually mattered, it would be more interesting. But in the end almost no one cares.
verbatim wrote: In that vein of your hospital-room example, I could give you a similar example of two neighbors, one of whom UNDERSTANDS things, while the other doesn't.
  • The one who doesn't understand things has a dead 12V battery after three days of a long-term power outage
  • The one who understands things is sleeping well, with plenty of reserve power, given the same outlay in cost!
Wrong - you're not talking about something that will greatly improve efficiency, you're just talking about saving a few bucks by bypassing some circuitry that some engineer (or maybe marketing person) thought was needed.
verbatim wrote: You sail expensive sailboats, right?
[... lots of drivel about sailing ...]
But, for the very few who want to win the race, UNDERSTANDING is the first thing about racing.
Don't you agree?
The question is, what race are you trying to win?

Again, I have nothing against knowledge. Go ahead, learn whatever floats your boat. The problem here is that you seem to think this issue is important when in reality no one cares! In reality, out of the 78896 members of this forum, there may be 5 members who would give this more than a simple "that's interesting."

username 5 - I have not joined in on gang style newbie flogging! Obviously, you know me well enough to know that isn't something I do.

This isn't at all about "newbie flogging"! It's about a person coming here with a great deal of knowledge, but with no idea how to communicate. I don't think putting people down because they don't have the same views as you do, and/or comparing a vagina to a voltage is something one does on a forum such as this one... newbie or oldbie!

Personally, I'm sorry you felt you had to get a new username to communicate your feelings.

not new but youve been here long enough to know why that happens and soon the gang you were with minutes ago will be all over you for that comment you know they think you have at least 5 names right

Did I misunderstand your words?
Yes, you did misunderstand; let me clarify: I have absolutely nothing against your going on a fool's errand!

Steve (on the other forum) is the guy testing it, not me; he's an EE (I'm a civil engineer).

I'm simply ASKING if there is any technical knowledge on this forum who knows about how ResMed power supplies work.
Apparently there are few technical people here who understand such things, where the bulk of the people here apparently think understanding their equipment is "bullshit" and "worthless".

That's fine, if that's the final answer to the question of whether anyone here understands the equipment that they use.
I just didn't know there were no people here who understand this part of their equipment when I opened this thread.
Yes, you asked a question and no one gave you the answer you hoped for. The truth is that a few of us knew that there were a few people working with this, but no one here cared because we see this as a silly thing to pursue. But that was the first few posts; the rest was just meaningless ranting.

First off, you need a remedial reading comprehension class.
OK, I confess, I didn't read everything you wrote. I don't think anyone will blame me for that.

None of us do. Thank goodness there are no imbeciles here.
