Thanks again for the details Glen

Do you think I could trouble you and buy a 6" section from you and mail it to Florida?

I don't know how important it is for replication but I do like to keep it as close as I can at first before making changes.

Let me know if it's possible and I could send you a PayPal payment for your costs.

Thanks again

Hi Luc,

I'm checking with my son, he's the glass blower and I think he has some in stock but is doing xmas ornaments right now that uses different sizes of tubing I'll see what I can do and PM you, ASAP !!!

Hi Luc,

The Red High Temp RTV Silicone #81409 is available at any auto parts store ....

The "Borosilicate Glass Tube" ( Pyrex ) 32 mm OD. x 6" long comes in a 5 foot length and has to be cut using a diamond tipped wet saw like is used for cutting ceramic tile or marble ( most tile retailers have saws and do cuts for a small fee ) and is available at most "glass" or "lamp working" suppliers like

Mountain Glass Arts, Inc. - Lampworking, Glass blowing and Bead Making supplies
simax meduim wall 32mm (25)
simax hvy 32mm (25)

and is fairly reasonably priced each stick ....

Thanks Glen,

that is a good price

I just bought all 3 variable resistors 10, 2K & 20k Ohm from the same eBay seller and the Nichrome wire from the other eBay seller since it is easier for me to pay with PayPal and I'm also having it delivered to Florida because I'm going to be there in the next couple of days for a 3 week stay.

Hopefully I'll receive all the parts and start testing.

Do you know at which store in Florida I can buy the Permatex red RTV Silicone?

Is that glass tube something I can buy off the shelve?

Thanks

Luc

Hi Luc,

The Ni Chrome wire can also be purchased here at a good price ...
Nickel Chromium Wire - 20AWG, 80% Nickel Content, 1/4 LB. Spool, 79ft per Spool - SmallParts.com

And the pots you selected should work fine ..... the higher ohm substitution on the 555 "off" pot will do as well.

Best of Luck

Glen

Thanks for the details Glen

I found this 10 ohms variable resistor on eBay: 10 ohm Trimmer Trim Pot Variable Resistor 3106Y (10) - eBay (item 380163362278 end time Oct-29-09 08:26:19 PDT) these give 25 turns of precision adjustment They will also fit on Groundloops board quite easily.

Also found this Nichrome wire: Heating Wire, Nichrome, 20 awg, Nickel-Chromium Alloy - eBay (item 280333596582 end time Nov-09-09 13:47:01 PST) 80% Nickel, 20% Chromium, 0.6348 ohms per foot at 68 degrees F, 20 gauge (0.032" diameter)

I have a question for the off time 15K pot. They are not available in variable resistor style like the above, so do you think a 20K pot will do since they have 25 turns of precision or should I get a 10K and add 5K resistors?

Thanks for your time Glen

Hi Luc,

The circuit for "Rosemary Ainslie COP>17 Heater Circuit" is a modified version of the Revised: August 12, 2009 circuit -
POST #2625

The changes are more closer to the original "Quantum" article -
"Quantum" October 2002

1) Mosfet gate potentiometer was a 5k now a 10 ohm precision tolerance for 5.3 to 5.8 ohms ..... I'm testing several methods from a modified 1 turn 100 ohm to a 20 turn trim pot ..... haven't quite decided this "is the most important part" to get the best results.

2) The 555 timer "off" was a 10K 10-turn now a 15K 10-turn for a 3% duty cycle .... shall be done but haven't yet at this time

The resistor is made from "Borosilicate Glass Tube" ( Pyrex ) 32 mm OD. x 6" long, the wire is AWG 20 [.032 dia] ( .6348 ohms ft ) "Ni Cr A" 80% nickel, 20% chromium, 10 ohms = 15.8316 feet @ .63165 ohms ft ( always measure wire resistance prior to winding to ensure proper ohm value could be longer or shorter depending on correct metal % values )

And using my barbecue coil winder

The last test is a good reference point but I'm a bit confused with the previous mountain of data. I'll be very ignorant here please ignore if it sounds stupid...

Wouldn't it be simpler to use a power supply with a fixed voltage and then sampling the current draw with the scope. Using this data one could then take the average draw over a certain time period to figure out how much power the power supply has given out?

Hi broli,

Sound good but I wouldn't recommend it at all ......

Using a power supply concerns me greatly especially when circuit return voltage spikes are from 70 to 100 volt pulses evident in all Images and Data taken..... even the TDS 3054C oscilloscope at some point getting over 610 volt spikes when it's capacity is 700 volts is getting very close to its limits.

I was very concerned just having a 12 volt 12 ah battery getting 70 to 100 volt spike pulses .... ever seen a battery blow up ???

Rant on MH's denials

MileHigh (or whoever he really is) made a statement questioning the DSO's math. He doesn't get away with questioning the Tek DSO's results: He is not qualified to do so, and is talking out of his rear.... Again.

If he doesn't LIKE the results, because it proves his 250 -some-odd posts there UTTERLY WRONG... , then that's too bad.... he must either disprove them with HIS OWN experiments, or accept them as the properly acquired and solid data sets that they are.

There is no attacking this with nothing to back you but your own naysaying.

Attacking this instrumentation methodology with a vague "problem with the scope" is completely lame, and totally without basis. It is proof that the motive IS NOT increasing scientific knowledge, but disproving the circuit no matter what. The only question then remaining, is if one is doing for fun or profit.

I would have predicted that exactly this would happen in earlier posts, since it was inevitable, but it was more fun to wait and watch it happen, then tell you all the above

You see folks, this is the really funny part... These so-called "skeptics" are all about proof and scientific method, until you ram it up their rectifiers. Then they revert to the very things they attack (and, admittedly, some have attacked with good reason in the past): And that is conclusions based on unscientific opinions and "mysticism".

But what they are hoping we don't notice is, that the concept of "It can't be!" IS MYSTICISM ITSELF!

And this, and especially that very thread at OU, is proof positive of that. But that's OK, because it shows us what they are really about

Its a new day here folks, an the dawn is glorious! The genre has been ratcheted up several notches in credibility and verifiable methodology. We can now tackle MANY technologies, and expect successes that will stand up to attack. This is a great milestone for us all who believe in Open Source, no matter what these experiments show: Because we are transcending our roots, and transforming into something the world has never seen before.

And it couldn't come at a better time.. Because this new power, this confidence, this surety of purpose and vision... Will soon be needed again

My deep gratitude goes out these fine people who are making it all happen.. Who are MAKING A REAL DIFFERENCE in this world. All you Researchers and Replicators out there, here and on a hundred other projects, who defy the slings and arrows, who refuse to be told by the narrow minded that they are wrong simply for TRYING... Who know, that science is not a religion that belongs to those who dogmatically adhere to it's Holy Scripture.... But that it really belongs to those with the guts and vision to see past the veils and strive for Truth.

"Quantum" 10 ohm Prototype Temperature Profiling

Hi everyone,

Here is the temperature profiling data on the "Quantum" 10 ohm Prototype load resistor that has been used in several of my posted tests. All temperature readings were taken covering as much as possible of the exterior surface of the resistor with a IR non contact thermometer using the maximum reading.

POWER SUPPLY -
Velleman PS3003U 0-30 VDC 3 Amp Regulated

IR non contact THERMOMETER-
Fluke 62 "mini"

Golly Fuzzy. Yet again. Where is this system's upper limit?



EDIT Just noted the harmonics in that last posting of yours. So sharp Fuzzy. I think this is Harvey's theme for possible optimised performance and it seems as if the data is consistent with this.

Rosemary Ainslie COP>17 Heater Circuit - TEST #7

Hi everyone,

Here is some data from a test run using a new 10 ohm Mosfet gate potentiometer to try to bring a better percentage accuracy to the required 5.8 to 5.3 ohms that seems to make this circuit run much more efficient. The test although a very short one was stopped for a good reason when the circuit seemed to self osculate and the Mosfet "drain" voltage went above 610 Volts and the battery's were spiking at around 98 Volts, I immediately terminated the test run because of possible damage to the equipment.

And the results were interesting to say the least ..... and the final Image and Data dump on the 100ns had gains that hasn't ever been seen before, and if possible to maintain these values would be incredible ......

This test was using the same components as TEST #3 and #5 with my prototype "Quantum" 10 ohm load resistor ......

************************************************** *******

Channel 1 - Mosfet source shunt
Channel 2 - Mosfet drain
Channel 3 - 555 Timer pin #3
Channel 4 - 24 VDC "Liquid" Lead Acid Battery Bank
