Claimed OU circuit of Rosemary Ainslie

[TinselKoala]

I have to say, those waveforms you posted up yesterday have to be among the ugliest I've seen in my whole career, and I've seen some ugly ones. I'm the guy that got Unitrol Sirens MOSFET's to work as linear PA amplifiers without melting into the ground, and there were a few of those that made waveforms like yours - bleagh. Clean that up, will 'ya? 

Hey, this mosfet is one tough little puppy. It takes a lot of abuse. I've only blown one, even though I've gotten them hot enough to melt the solder a few times, and scorch my bamboo "breadboard" that I bought back when Aaron was claiming these oscillations with a circuit that couldn't produce them.
(Of course even that one still works, when I hook it up like Yucca said...)

But I don't think it's really the mosfet doing this. It's just responding to what it's being told by the 555 timer circuit. Without that misbehaving 555 the mosfet is also well-behaved.

Or, at worst, it's an interaction between the mosfet and the unstable 555 circuit. As Yucca says, there are ways to reduce the heat in the mosfet. But I don't see any ways to make the load produce more energy out than in.

I guess we'll just have to wait for Aaron to show us how to do that. Since it's pretty clear we aren't discussing the Ainslie circuit any more.

i am pretty sure no one has ever said the irfpg50 is required for fantabulous COP>17. can you direct us to this statement? or is it one of those imaginary ones like tk's "predicted by..." statement that somehow neither he nor his sycophants can find? what has been stated about the irfpg50 repeatedly is that since it was specified in the original schematic using something else was bad scientific method in regards to replication.

Sorry you got me, I was wrong to say that, I shall now set about flagellating myself with 1m of 18AWG cable onto which is soldered numerous blown FETs.

Whats really bad scientific method is publishing a schematic containing a timer stage with a completely wrong duty cycle, and then saying "Oh I dunno, it may be wrong yeah whatever, can I bum a ciggy off you? hey did you see that zippon?". Because the schematic was published the error was multiplied, hindering many replication attempts.

yes, you were wrong to say that. this the real world, where you are accountable for your words, something your naked emperor can't seem to grasp. at least you know when to admit you're wrong, however sarcastic that admission may be... 

ahhh i see, so you hold RMA to a different standard than you hold your emperor. hmmm, that's interesting. any particular reason? speaking of errors, you haven't come across that "predicted by..." post from your naked emperor have you?

RMA and TK are both just folk, probably neither have a real bad bone in their bodies.

RMA is setting herself up for a bit of ribbing though, what with the tall claims and absolutely no experimental data to back it up. Hell if it were me I´d have posted working circuits to various people for verification through independent calorimetry.

edit: removed some bad vibes, just like Jack Herer would have us all do.
