I don't want to reproduce the full document. Life is based on trust. People who find it difficult to trust do so because they are untrustworthy.
And there we have it. You say you have all the documentation. Then you offer an excuse for not showing it. When that excuse is demolished, you say "trust me". That is not how honest people behave. You can say what you like, you can claim to be "upright", you can imprecate the character of your critics, but when you wheedle out of every opportunity that is offered to you to substantiate your claims it is, at the very least, highly suspicious.
My original take on you was that you were either naive or inexperienced, then it changed to thinking that you were a little strange and a bit self-deluded and now it has changed again. With your constant twisting and turning to avoid actually answering your critics and sceptics, while still claiming that you have proof, there is now only one reasonable conclusion left, that you are acting deliberately. I believe that you have no proof and you know that the minute you produced what you actually have then the whole house of cards would come tumbling down and you would be publicly revealed for what you are.
I actually misread the cert. Since Fluke Calibration encouraged me to display it with personally identifying info obfuscated--which was my actual objection--I have posted it. Don't sell yourself short by selling other people short. All things are pure to the pure, Suspicion is the device of a guilty mind.
I think it is the bare minimum expectation that a calibration lab would have certified standards. I've been honest all my life. I've even gotten myself into trouble because of it. I didn't set out to build voltage standards. I found out about precision reference ICs from a blog post by a hospital tech in Tanzania.
I just wanted something to calibrate 3-1/2 digit meters. I wasn't trying to build anything spectacular. But, I told my father about it, and he tested it. He's a MSEE from Marquette, with 30 years experience. If anyone thinks I'm lying about that, I make a challenge: If I'm not lying, my challenger has to make a video of himself eating his shorts and post it online. If I'm lying, I have to do the same thing. But bear this in mind before calling me a liar again: my Dad is a member of this board, and I'd love to see one of my undeserved critics eat his shorts!
My Dad told me the bare regulator IC was better than a standard cell. So, I took that to mean it was good. I didn't want to make any more standards. I just wanted one for myself. But my Dad wanted one. So, I made another one. All it was was a bare regulator IC inside a box with wires directly off the pins connected to banana sockets set in the enclosure.
So, then I dropped it. I wasn't interested in making any more of them. But my Dad burned his up with reverse polarity on the input. So, I had to make another one, this time with a diode on the input ground. I really didn't see the potential in improving the performance. I was happy as a writer at that time. I played around with electronics projects in my spare time, mainly repair work, but some original projects.
However, my Dad encouraged me to develop a product around the regulator IC. Natively, the IC is 10V +- 0.05%, with 2.5ppm/degreeC drift. I just thought if there was any potential, someone would have exploited it by then. My original aim was +-6ppm at a certain temperature. That worked, but it was nothing to write home about. A lot of people bought those. They were cheap.
But my Dad thought the product could be better. We even got into a shouting match. But it turned out he was right. I was relying on the last digit of a DMM to estimate the stability of the IC, which gave the illusion that it wasn't very stable. But I bought a higher precision meter, and I found that the IC was much more stable than predicted.
So, my aims at that point were temperature compensation and long-term drift. I say I inspired the design from God, but I actually only inspired a part of the TC from God. Maybe it just came to me in a creative moment. It all depends on how you look at it.
The TC circuit simply varies the gain on the output with temperature, in the opposite direction the regulator IC drifts with temperature. One of the difficulties the people on this board run into is attempting to design a standard that will maintain accuracy under harsh environmental conditions. Another difficulty I see is failure to invest sufficient capital, effort and time.
R&D is no place to scrimp. I still have to find a PCB design that works, but I can hardly be blamed for making my instrument by hand, which costs 3x as much as prefab. People are actually getting more for their money. And, most buyers don't really care, as long as it works.
I'm making a guarantee. If one of our standards ever fails, it can be sent back for inspection. If it is determined that the failure was a result of faulty soldering, the user gets a free repair and recal. But none so far have failed that
I'm aware of.
So, when everyone else my age was out partying and having fun, I was hold up in my shop doing R&D. I tried 113 designs before I found one that worked well. I am very concerned with maintaining an accurate volt. No one should falsify the volt, or any other standard. It costs me a lot to maintain certified standards.
The cert I posted on 10/20/2017 cost almost 800.00USD, and even more if you include shipping. I make about 6,000.00USD/yr selling standards. If I quit tomorrow I wouldn't miss it. But I fill an important void in the marketplace. Many of my buyers pay me great respect for my product. And I'd like to pass the business to my son someday.
For my critics on this board, I'm not the problem. I have been nothing but honest and forthright. When the world gets to the point that no evidence is required to impugn the upright, it is a very dangerous time indeed. No one is safe, because if it can happen to one person, it can happen to anyone.
I have now posted to this thread not one but two cal certs. If that isn't enough to make my unearned critics blush, they have not the wisdom to be embarrassed.
