Claimed OU circuit of Rosemary Ainslie

Thanks Groundloop for confirming the emitted RF levels. As expected, they are insignificant compared to the thermal energy from the resistor.

PS. I obtained another power resistor today....a whopper!

10 Ohm
225 Watt
64uH
about 10" in length, and about 1" in diameter.

Fuzzy,

Regarding your post #2834 at EF:

First Shot: F=38.4kHz, PW=7us, Duty=27%

A relatively clean 555 output at 12V.

The remaining shots: F=588kHz, PW=900ns, Duty = 55%

The 555 output is struggling. HOWEVER, notice with every transition (especially the sharp but only partial HI to LO transition) in the 555's wave form the corresponding "spike" and resonance on the load shunt. This is the differentiation I am talking about. The ringing resonance is indeed about 8.3MHz as you mentioned. If you look closely, you'll notice yet another resonance much higher in frequency on the sharp negative spikes (see last scope shot).

This is indeed a complex wave form due to the interaction of the 555's output and the resonance of the load, but by definition it is periodic.

Thanks for the great reporting

Glen,

This may sound like a strange proposition, but indulge me here if you would.

What I would like to see is what happens if you disconnect the load from the 12V source, and tie the load end to GND. Leave power to the 555 as before, but ground the High end of the load resistor and run the same scope shots.

I will not be surprised if you see exactly the same wave forms as before when the load was tied to +12V. I could be wrong, but I think you'll see something similar at least.

Well at least we are seeing some action.

Rosemary:

Don't forget the coil-resistor discharge creates a clockwise current flow.  Any counterclockwise current flow is minuscule.  We don't have to debate Aaron's statement, my question was more rhetorical than real.  I view his statement as an awkward juxtaposition of words that one would normally associate with the types of conversational English mistakes that everybody makes.  Aaron is not too much of a details person, he is more of a "driver" personality type so his written prose is very much conversational in flow, mistakes and all.

Aaron's latest clip is based on a misunderstanding, no surprise there.  The "logic" behind removing the caps from the 555 circuit is positively Bizarro.  This quote sums up the feeling, "Calibrated 5% carbon resistors, point two-five ohms."

Sorry to pick on Aaron, but it is hard to believe that he has been working with electronics and scopes for 10 years.  Behind all of the bravado he is really struggling and the chances of him producing good sound data are a longshot.

MileHigh - this is why Aaron gave up reading you.  Give the guy a break.  I've yet to meet anyone with that much IQ - Unless it's you.  And we all have our styles.  Personally I'm into the 'coversational' number.  He's a pleasure to listen to.

Hi .99

I'm a bit confused here are you talking about the "Ainslie - Murakami Negitive Dominant Waveform Generator Circuit" here ...... http://www.energeticforum.com/67702-post2627.html  because if you are Harvey has also asked for the source waveform superimposed with the drain waveform for timing comparisons .... I could try to accommodate both requests yours and his given the time with the loaned Tektronix Scope I'll have this weekend, and I can duplicate the "Tektronix TDS 3054C Testing - Part #2 Post" that was done several weeks ago http://www.energeticforum.com/68575-post2766.html
Aaron does have the first made prototype 10 ohm Quantum replication resister, but I now have a new same configuration untested one that will be used for testing.

If your talking about the "Rosemary Ainslie COP>17 Heater Circuit" which was the last posting of mine at Energetic http://www.energeticforum.com/69546-post2834.html the 10 ohm load resister is on a 24 VDC battery bank no 12 VDC on the "Source" only the 555 circuit  ....

Did you notice the flat line amplitude of Channel 1 (A1) went up 34 mV (x10) when the 24 volt battery bank was connected from the first photo showing the 555 pin #3 output

At any rate I'm going to make the best of the kind gift of the use of the Tektronix Scope that Lisa from Tektronix has arranged to further the data, understanding and the verification of some findings of both circuits.
