The PDF is looking pretty good now thanks to you my friend Alex thanks for the advice Bro, thats easy to try, winding Glens inductor now. ill get onto it ASAP my friend.I have a contact at the university, with some equipment will try and match Aaron's and Glens test for Rose/ALL.

Hi Glen,

4:00AM here, and I still need to hit the racks, but I wanted to stop in and see how things were going.

One thing I would like to see: Could you widen that view of the negative pulse on the Source? I am particularly interested in the activity of the source just as the body diode enters conduction. I see there is some cancellation going on there, but it is all too narrow to determine the progression.

Thanx again for all this. Hopefully when I awake I can get a look at the CSV stuff.

Cheers,

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.

elias - MANY THANKS FOR THE TEST. Your pictures are amazingly sharp. I'm afraid I'm not sure how to advise you on your test data evaluation. I'm hoping Aaron can oblige or someone? Failing which I'll try and get back to you tomorrow.

I love your recommended energies btw. And again. Thanks very much for the input here.

[elias]

Great stuff. Btw - I see you're hardly a new member? Just new to this thread. Sorry about that. It looks like I'm actually the newbie here.

This thread was in my mind in a corner and i also read your theories about zipons and so on, I have been so grateful. Your theory about a universe being created from a single infinitesimal God particle totally resonates with me. This forum has been a wonderful place for me to learn and grow.

People like you have made this forum a wonderful place to be.

My first replication

Hi,

I finally replicated it yesterday. I used a 12 volt DC adapter and my current meter was showing 0.51A at 50% duty cycle 24KHz set on my signal generator. The resister warmed up in about a minute and I suppose it was around 70 degrees Celsius. Because it was hot to the touch, as I couldn't hold my fingers on it for more than 2 or 3 seconds. I don't have thermometer yet, so I couldn't make accurate measurements.

I used a 20% duty cycle signal at 2400Hz, and I could get the resistive element to warm up in the first minutes. I have to get a thermometer.

Here are the pictures:






Rosemary,
I wonder about measuring the heat? Can you offer an easy way to measure the Heat Energy output?
This was an interesting experiment, as it can be scaled up so easily.

I also used my 18v adapter, and this made the resistive inductive element get pretty hot, as it was giving off noticeable heat. The current was 0.8A in this case.

Thank you
Elias

Hi Fuzzy,

Excellent work, m8.

Looking at your drawing, i was wondering what you are going to attach that thermocouple to.

A "J" or "K" TC would probably be the most accurate means available for these temp ranges, but as far as i know, they always require a separate Signal Conditioner / Amplifier box to get a linear output. This is because their voltage output per degree is "naturally" non-linear, and the calibrated signal conditioner, set for the specific type of TC, has the proper table built in to "linearize" the output. Otherwise, it is a bit of a nightmare to use the table & manually do the calcs to get the temps right from the V output (... although it is possible to do, the tables are available).

So unless you have a TC signal conditioner, you may consider using a thermistor instead, like the DMM options, as they have linear outputs and can be used without a separate "front end" signal conditioner more easily.

Fuzzy,

Very nice and neat. Sorry I missed that post.

[FuzzyTomCat]

Hi all,

Could someone fill me in on the procedure measuring heat for this experiment? I saw the logging on ambient temp and component temps. Does this means we're using air as a medium to measure dissipated heat? Thanks.

@ quantumuppercut

At The present time my only method is to do temperature measurements in ambient air using a Fluke 62 "mini" IR thermometer .... to do surface tests of components and using the "Maximum" temperature reading on each component for recording purposes .... although I have shown a alternate method for my prototype
Quantum 10 ohm "Load Resistor" a method in a earlier posting here at Energetic ..... I don't know at this point before more data is acquired from the planned tests I have if this will be possible or useful prior to returning the TDS 3054C oscilliscope to the Tektronix Corporation thats on loan ....

Glen!

Fantastic - really good work there. Great record keeping to boot

This is exactly what I was expecting on the Drain and Source, I can't express my thanks enough for what you've shown. And that negative spike perfectly aligned with the gate falling edge , so glad you moved the marker over on those shots so we could really see it's full impact. That one is the capacitive gate-source feed through that occurs 1.3 divisions before the inductive collapse. Very interesting how well that passes through there. But the Drain and Source activity after the FET is off, that is the really interesting thing.

As the magnetic field collapses around the load resistor the Drain spikes to what, 220V? That is a positive going voltage. At the exact

Hi Harvey

Thanks for the words of encouragement ...... any other information or data you may need just ask. I thought also mentioning the data on my Mosfet "shunt" resistor is a "Dale" RS-2B / .25 ohm / 3 watt / 3 % tolerance

The 220 volt spike on the Mosfet drain .... where it comes from .... and where it goes .... could be the question of the day
