it's always entertaining when people like you start projecting.

I am NOT an expert on CPAP "settings", but, I'm sure there probably "are" settings which could damage your health.

Ok verbatim - you just disqualified your self as some sort "expert".

This thread is totally worthless and seems to function as some sort of club you want to use on long time effective members (which you are not)

Do we know what effects the different voltages on the signal line have on the operation of the cpap machine, if any? For example, does it cause the heater to be disabled when running on batteries? That would be a useful feature but the product page at resmed indicates that this is not the case - at least in the case of the official 90 watt converter. It says that it powers not only the cpap but the humidifier and heated hose.

Maybe the original plan was that the 30 or 60 watt power supplies would disable these non-essential accessories when running on battery? Something like 90 watt would power cpap, humidifier, and heated hose. 60 watt would power cpap and humidifier. And 30 watt would power only cpap. That would be potentially useful.

Also, are there 30 and 60 watt converters available anywhere? I only see resmed talk about the 90 watt one.

Wow! I picked an interesting time to take a few days to go off-off-grid ... I was spared the temptation of replying one post at a time!

First I have to applaud verbatim for his intellectual curiosity in researching this issue. However, its a bit of a Fool's Errand because I doubt anyone would want to risk their $600 to $1500 investment to save a few dollars. Especially when most of us consider their pump a life support device that we use for a third of every day! Imagine coming into your loved one's hospital room and seeing an IC and a few resistors dangling off a power cord and the nurse tells you they saved a few dollars by hacking the respirator!

Yes I know that this is unlikely to go up in flames, but I certainly can't rule out the possibility that it would pop something in the ResMed pump circuitry. Even if it was covered on warranty it means several weeks down time. At the very least, I can't imagine trying it on anything but a throw away spare. And since ResMed would never certify it, there's no way to market this. And why would you even want it since all it really does is allow you run off of a 24V battery which would undoubtedly actually be two smaller 12V batteries? The commercial product, albeit pricey, does exactly what one wants. (Ironically, I may be the only person here that regularly runs a cpap on a pair of 6V batteries! But I digress.)

If you go back through my posts you'll find that a number of times I responded to the question of "ResMed versus Respironics" by bringing up the issue of 12V versus 24V and the proprietary power plug. I've strongly advised campers to take this into account. There are other issues involved, and many people don't actually get a choice on the brand, so I've often advised using the ResMed 12/24 converter.

Maybe after a few dozen people have reported success with a hack like this I might look at it differently. Or maybe if the solution was simpler, such as a button cell on the third pin, etc. Actually the biggest issue I see is not for people camping but emergency situations like forgetting the power supply - A Respironics supply can be built with 8 D-cells, but not a ResMed.

On a more philosophical note: As soon as someone starts yelling "Off Topic" and "Contributing nothing!" I pretty much discount everything they say after that. I generally enjoy the off topic contributions much more than "on topic," which tend to be boring and repetitive. Probably every interesting advance was considered "Off Topic" by the Powers That Be. And frankly, PR's skeptical comments are, in a strict sense, probably more relevant then verbatim's polemics!

And lest I forget:

Thank's, I appreciate that. BTW, you might notice that I try to follow a few rules. Almost everything I suggest is something I've already done, most the components are standard easy to buy and use parts with multiple sources, and all are used in the way they are intended. I shy away from things like power packs designed to recharge cell phones and computers or jump starters because they tend to have unexpected problems.

Speaking on behalf of rocket scientists everywhere, I would point out that most rocket disasters are caused by very simple blunders and poor decisions. They were not caused by fundamental science that was too complicated. Changing cpap pressure is well documented in the manuals, and the procedure to determine the proper pressure has be worked out by thousands of trials. And many of us have consulted our doctors so we know this is not an overly dangerous process. Hacking a $1000 life support device to save a few dozen bucks, on the other hand, feels like it might be a poor decision.

1. You are a moron.
2. The thread is worthwhile ONLY to intelligent people.
3. Since you are a moron (who wouldn't know a resistor from a vagina), the thread is worthless to you.

Yet, you still post?
Hence, you are a moron who is doing exactly what you say "I" do, which is post for no good reason whatsoever.

Please put me on foe, will you.
You are too stupid to even think about (I hope you win a Darwin award soon so that you don't cloud up my threads with your moronic trash).

Why did you even bother to post?
What technical value or technical question did you ADD to this thread?

I'm going to respond only to what you wrote - so that others may benefit.

NUMBER ONE: I'm not an expert in ANYTHING here; and I never said I was.
And I wouldn't be asking such basic questions as I am if I were!
NUMBER TWO: Never believe ANYONE who simply "says" they're an expert!
Experts prove their expertise with their technical merit, e.g., Pugsy, CapnLoki, Yaconsult (just as morons prove they're imbeciles with what they write, such as pale rider, sonny boy, and now you - the new idiot in the crowd who has no value to add, black spinner).

HINT:
An intelligent person evaluates the TECHNICAL MERIT of what a person writes.
From THAT technical merit, they determine the qualifications of the person.

DOUBLE HINT:
Don't believe ANYONE when they "say" they're an expert.

For example, palerider is a poster child for the Dunning/Kruger effect:

Are you a complete idiot?
Do you even KNOW what this thread is about?

What you meant to say is "I'm too stupid to UNDERSTAND what this thread is about!".

While we're talking extremely simple stuff here, it's still far beyond your capacity to comprehend.
But why do you post that? For all the world to know?

Why do you shout out "I"m too stupid to understand a circuit diagram?"

I'll never understand why people like you (and palerider and sonny boy, et al.) post, just to proclaim to all the world that "This thread is so far beyond my comprehension that [blackspinner] must tell the world that it's worthless to people as stupid as black spinner is?"

I realize this is a psychological question, but, WHY do you proclaim to the entire world that you're too stupid to understand a patent description or a circuit diagram, by saying, therefore, because YOU ARE TOO STUPID to understand it, that it's therefore "worthless"?

Actually, since I posted something of technical value, and you contributed negative value, it's YOU who is treating this thread as your own private club, proclaining that it's "worthless" simply because you're too stupid to understand what we're talking about.

The proof that you treat this thread as your private club is the fact that you had absolutely nothing of value to add, yet, you proudly proclaimed that your assessment of the technical value of this thread is "worthless".

I have to wonder if you too belong in the Dunning/Kruger club.
Read up on it.

You too are a poster child because you made a technical assessment on something you know absolutely nothing about, and you proclaimed the technical merits of this thread as "worthless", all the while you couldn't possibly have understood a single word of the thread.

And then, after that, you proclaim that it's "my club", when, you don't even belong in the league of sensible humans, let alone intelligent beings.

You actually think this thread's technical merits are "worthless"; yet, you know understand ZERO of what we're talking about.
It hurts to think there ARE people as stupid as you in this world.

well, it didn't take long for verbatim's true colors to show through...

you disagree with him, and he wishes for your death, I hope his supporters are really proud...

what a low life.

and none worthwhile... it started out with really stupid clueless thick as a brick questions, and now he's flooding the forum with his 'circuit'... (six threads he's posted in so far, at least, same crap.. it'd be nice if he'd at least learn how to post thumbnails with clickthroughs, but I'm sure that's too much to ask.. even though I DID give him instructions.

this just in, footage leaked online of verbatim getting ready to post his next death wish:
