Hi Glen,

Seems to be good results, congratulations.
I had a question, it seems that your circuit is operating at around 500KHz according to the scope shots, is this correct? The period seems to be 2us.

Elias

Hi elias,

Thanks, I'm not totally positive on the 500KHz because I didn't have my frequency counter attached ... so the only thing I could go by was the Channel 1 information on the scope screen right side under the "mean" mV reading where the frequency numbers are, and it seemed to average 68MHz, next time I'll connect my counter and find out exactly for you and other replicators.

FuzzyTomCat and All,

Congratulation for doing a very good job. :-)

If there is an solution to find even better "voltage spike" capturing methods
then I'm sure we can find them.

Hi Rose/ALL.

Dr Stiffler is probably one of the only other ones up there, imagine if we all had our own resourced backed non profit research center we would change the world over night.

Hi Ash. How exciting is this? Indeed I'm sharing that dream for a research centre. But I'm hoping that Jibbguy will do his bit in getting this to mainstream.

A big thank you to open source. Definitely the way to go.

Hi Rose/ALL.

Yes we all do Glen/Harvey , i am impressed with yourself Rose as you have shown that working with open source engineers is beneficial when having a device with a COP+1. There will be more benefits, soon the establishment will have to accept it and will owe you a HUGE apology.

Dr Stiffler is probably one of the only other ones up there, imagine if we all had our own resourced backed non profit research center we would change the world over night. Thanks Glen/ALL. New doc will be up in 30 minutes with Alex's and all's data. Soon as its optimized thanks to Fuzzy il have the run time tests on the farm of the circuit in the real world to report and added to Rossie's doc, got a solar Bedini charger for that and Aaron's negative wave

Hi Harvey,

Thanks for the doing the 40us data crunches ..... I really like the totals

The experimenters using a power supply for operating the 24VDC may not want to do this with 70 Volt spikes going back into their power supply, plus the gains might never show up ... power with no where to go. I'm just wondering how to capture more from the spikes .... but I'm sure it will come to me soon

Glen

Indeed it will Fuzzy. If you found this you can do just about anything. Well done again indeed. And thank you so, so much for EVERYTHING. I'm dizzy with excitement still. I really owe you big time.

[FuzzyTomCat]

Fuzzy, this is truly great!

We need to mention that these are straight Ohmic calculations and no effort has been made toward differentiating the current lead/lag in the inductor as we know the 'Drain' (CH2) value is not a purely resistive reference. However, preliminary observations would indicate a strong negative average on the battery power. This is corroborated by the reduced draw down rate as compared to previous runs not operating in this mode.

This data should be sufficient such that when compared to the thermal output it should confirm conclusively that the Rosemary Ainslie configuration does produce more output power than it uses on average - unless of course I have made a mistake in my calculations above which is presented here for review.

And may I say - at the risk of boring the guys/girls at TEKTRONIX

WHERE WOULD WE BE WITHOUT YOU?

Many, many thanks for the use of your brilliant instrument. I've said it before. Anyone want to argue these results will need to take up their quarrel with God.

ASH MANY THANKS INDEED. Truly appreciated. Will get back to you later on this.

[ashtweth]

Never too much trouble for you Rose . Okay here they all are, now as for winzip, i use Winrar (which can pretty much unzip any thing,) its a FREE program WinRAR archiver, a powerful tool to process RAR and ZIP files

Let me know if is missed any thing Rosie, if you have any probs drop me an email ashtweth@gmail.com and ill attach them un zipped

Hi Rose, please tell me what files and ill upload them to megaupload dot com for you, they are easy as putting in a code and starting the down load.

Ash

Ash you're a sweetheart. It's the CSV files that Fuzzy references. But if you can't manage this not to worry. Fuzzy's sent them to me in 'zipped' format. Just need to see if I can get them unzipped???? Still a dinosaur

[ashtweth]

Hi Fuzzy. Yet again. THANK YOU FOR THESE AMAZING RESULTS AND FOR THE HARD WORK IN COLLATING IT ALL.

I spent a frustrating day trying to open the files with rapidshare. It gets into a loop. I hope it's easier at your end. Eventually got this opened by Carine at Tektronix (SA) - but she could only post this on Skype. She also had some considerable difficulty with the free number. Eventually opened with the 'member?' option. It's complicated but my Skype is on the wrong computer. Any help here would be most appreciated.

I also paid some tribute to your skills here at OU.Com. But - for the record - I am just so impressed with your professionalism in the way you present the data. And can't wait to do the analysis.

Still the coolest cat on the block.
