Claimed OU circuit of Rosemary Ainslie

OK - MileHigh. Here's the thing. Fuzzy has a glass base. All that's needed is to plug both ends and the resistor will have no 'wafting' air currents. I'm sure he's attended to this. That way - its position is largly immaterial. Your chimney introduces too many variables. But I agree that it's better to keep it off surfaces. Your point here is taken.

And I tend to agree with Ash - on all things.

Fuzzy:

It is just applied knowledge, simple as that. There is nothing to reference. I wouldn't be supprised if Poynt would graciously "open source" the setup - Gotoluc has one of his own already.

Rosemary:

Just about any resistor setup is valid as long as you keep it thermally isolated from the rest of the environment. If both ends of the tube are blocked then your recorded temperatures will be higher. That does not matter, blocked or unblocked holes can generate valid data sets.

All that you want is for the thermal resistance to remain stable for any setup, and to keep your thermal capacitance constant.

Anyway, I am happy that you are happy about Glen's testing and his replication. You may recall that two months ago I was arguing that this was the way to go.

Hi MileHigh. No I don't recall you arguing this. But my memory is not what it was. I sort of remember a suggestion to hang the resistor vertically in the air? Was I dreaming?

edit - sorry I misread you here. Yes I do remember you asking for a full replication. But why does this not also delight you MileHigh? I cannot tell you how disappointed I am. I thought you'd be over the moon.

Ha ha! Don't be coy now, you know I was talking about running the standard test - the real 3% (or greater) duty cycle setup witout going crazy with the oscillations first.

Ok I will reply here to conserve the "Internet trees." (lousy joke but at least no singing) Yes I am happy that Glen did a straight replication, absolutely. More interesting buzz has been generated in the past week than the previous six weeks.

MileHigh - in case you missed this.
