Claimed OU circuit of Rosemary Ainslie

[poynt99]

Been working on Fuzzy's wave forms. Here is the load wave form (with his for comparison).

Average of the wave form is about 0.218mV. That is somewhat strange. It should be 0V 

Glen, I noticed for all the other scope shots with the 3054C, the drive interval seems to have been about one half (i.e. double the frequency) to about 4us. Did you change the settings for the two shots, i.e the one on the Fluke and those on the Tek?

Also, those are across the shunt? I feel you must have changed the settings because the voltage is quite high in comparison to the previous load voltage shot on the Fluke. With only 250mV across the load, we shouldn't be seeing 100-150mV on the shunt. But then maybe you're into some strange mode.

****For the sim I included the output section of the 555 (4 resistors, and 4 transistors according to the National LM555 spec sheet), to confirm something about the series supply resistance. This greatly affects the drive capability of the 555 and is what is partially responsible for the "choked" drive to the MOSFET. In fact the MOSFET isn't conducting at all in this mode. All the excitation seen in the inductive resistor is supplied by the 555 itself.****

And by the way MH - let me point something out to you.  If you were half way as good as you think you are you would have picked up that there's serious misrepresentations in the quantum article and the IET paper relating to the R10 Ohm.  Either the gauge is wrong or the inductance is wrong.  If you and TK were half way as astute as you think you are you would have seen this way back.  The truth is that Fuzzy, Aaron et al -  picked up on this at the opening chapters and have been politely skirting reference to this fact - I think to spare me the humiliation.  But I'm more than ready to own up to it.  So you see, MilesOfftheMark - you're out of line unless you direct your license to criticise -  at me. 

And I'm sorry everyone that I have made this obvious error.  It makes replication difficult - to say the least.

And Poynt, your work here is stunning.

.99:

Could it be something like the choked 555 manages to output a feeble pulse feeding off the charged 100 uF capacitor.  Each time it manages a pulse it sucks the life out of the cap and goes back to sleep until enough juice is available for the next choke cycle.  This gives the MOSFET a bit of a tickle and excites a ring down across the coil-resistor?  You indicated that MOSFET is never even switched on, so are you implying a capacitively coupled energy transfer across a capacitive junction?  I don't have the fire in my belly to truly follow what's going on here.

You know the old Monty Python cheese shop skit?  I just want cheddar cheese.  Cheddar cheese!  A test on the original original original setup with the new PCB.  Hang the coil-resistor vertically in mid air, trust me!  Anybody listening?

Rosemary:

Flowers are wilting everywhere.

Rosemary II:

I have no clue what you are talking about.  If you are trying to imply that I should be able to tell you that the specs for the inductive resistor don't make sense just by eyeballing it that is totally ridiculous.  Nor am I a coil nerd.  Plus that question should be self-posed, don't you think?  You own the paper, you merit the bold typeface.  How come there was no precise measurement of the 10-ohm inductive resistor for your thermal profiling if we assume that it was a +/-5% resistor?  Say cheese.

   MileReallyReallyLow - if the flowers are dying it's because they're bearing fruit.

  I realise this.  But we all have some limitations.  Yours is in the distance you can go.

No.  I'm not saying that.  You don't need to 'eyeball' it.  You need to apply some math and some basic knowledge of resistive wire.  I assure you Aaron, Fuzzy and Harvey spotted it immediately.  What is wrong with you that you never saw this?  Good Heavens.
