Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

[MrMag]

Rose, your kidding me right? We are not talking about a 17 hour test here are we. Do you even bother to read the post from us asking to do a draw down test or are you just thinking of finding ways to attack us. I am not asking about battery performance, I am asking to run a continuous test to see if your circuit can keep the batteries charged. If you don't understand this simple request I can try to put it in a simpler manner for you. ( I typed the above two sentences very slowly for your convenience).

Correct - A battery comparison test probably doesn't mean anything.

Running your circuit continuously for a duration of the battery watt/hour rating will prove something. It will prove if your device performs like you say it will or not. It's that simple.

In the last 10 years have you ran your circuit continuous for the above time period? If not, Why?

I am not sure what you have against screen names. Is this all you have left to attack us with? Does it really matter what I use as a name on here? If we ask relevant questions and ask for relevant test does it really matter what I call myself? Maybe, just maybe, a lot of us use screen names so that we are not personally attacked by deranged people. I don't necessarily mean you but there are some out there.

If you really want people to take you serious, you should start talking a little more professionally. No wonder you can't get any "Experts" to review your work. Your present attitude towards people who have made a simple request of you is very disturbing. What do you think the "Experts" would think of this.

"Added.  And while I'm at it -  may I also add that I find NOTHING quite as despicable and contemptible and cowardly as the extraordinary freedoms you all indulge in your opinion of my hard work - when you all shelter behind those 'screen names' as Fuzzy rather pathetically refers to it.  If you're going to show the courage of your convictions then post under your own name.  Else there's the very real danger that not only will you be considered a big mouthed bully - but that you're a self-serving hypocritcal coward to boot. JUST LEVEL THOSE PLAYING FIELDS. It's easy playing fast and loose with other people's reputations.  Put your own on the line and be counted. "

I don't know about that Rosey, All I asked is for you to do a continuous test of your circuit. You are the one coming across as the big mouth bully. All the name calling when you don't even know us or our background. Even if I told you my real name, would you know my background or qualifications. I'll tell you what, find 5 experts and have them request my real name and then I'll do it. And, as far as ruining your reputation, your doing a pretty good job of that yourself. I don't think you need help from me or anyone else.

I started out here giving you the benefit of the doubt. All you have done is attack me. I honestly think that you have something to hide by just making up excuse not to perform the test we have asked you to do. I am starting to think that all those comments in that blog about you are true.
I really think you need to get some psychiatric help.

MrMag et al,

A draw down test against the amp-hour rating of the battery is only doable if you have an accurate and reliable measurement of the power consumption, or more specifically, the net average ampere usage.

Unless a DMM is placed across the CSR, or if the scope is set to compute MEAN of the CSR trace, we would not know what the net average ampere usage is. And this is a volatile subject all on its own because of the misunderstanding regarding probe orientation.

The best test as I mentioned long ago, is a battery state of charge (SOC) measurement over time. The beauty of this method is that it does not require weeks or months of testing. At most all that would be required is about a week. Take a SOC reading every 12 hours, plot the readings out vs. time, and look for a trend.

Or possibly, with this meter sufficient testing would be done in less than an hour.

A DC amp-hour meter. $60

I'm not sure how well it works with pulsed currents though.

Thanx poynt, but isn't she running with a heater connected to boil water? If this is the case, wouldn't the continuous monitoring be irrelevant. Over time the batteries would slowly discharge. Or does the circuit in question not have the heating element in place.

[poynt99]

Indeed Rose has used the element to boil water before.

Working backwards from a boiling quantity of water (the output) to determine the net average input current would require a bit of mathematical acrobatics I think.

IMHO, it would be easier to monitor the batteries' SOC over time, OR accurately measure the net average current through the CSR.
