Now you know why a lot of guys have disappeared.
They got tired of posting circuits only to have them show up on ebay a month later.
To really **** a guy off; the ebay sellers don't support their product; usually. The original designer gets emails wanting to know why the knock off circuit doesn't work right and is called names for not supporting it.
I know one person who posted a schematic and board with an error. On purpose. Sure enough, a month later the board shows up on ebay, error and all.

/OFF:/ No, I am not working for free of course. I am just in the same monkey-wheel like you....🙁
It is hard to get out from there I know. But sometime it will be a must: the enviroment, your body, your mind... so on will collapse and say: stop! Enough from this bu*lsh*t...
It could be a wounderful place here. If we would make it so... But we are divided (with flase flags, e.g. money), so it is not so easy... or much easier as most of the people would think? That's how this splitted world works. Too much? /:OFF/

It is a cheeky thing selling out not working products, I would never make it. But sharing my experiences for people who like to use it (rationally), developing it forward (developing together), it`s good thing...🙂

Another DIYer who wants a free ride, no work, no effort, no learning.
Copy other peoples stuff, expect it for free. Then complain if it doesn't work.
I think you need to go tell your boss you can work for free and their copyrights and patents, the items that allow you to have a job, are not needed and should be placed in public domain, for free.
I have purchased items from Guido many times over the years, he feeds himself like this. Can you please tell him that he does not need to be paid for his work? That you are more important than his grocery bill?
I'm beginning to understand why Jocko hates DIYers.

Not anger, frustration with guys like you that want it handed to them on a platter. I quit posting years ago because of guys like you.
And now you are doing just the opposite 😀
If you design for a living then DIY is not the right place.
Here we try to do things together, proposing, helping.
Look how I do, or plan to do, it.If you like it try it too.
If it's to complicated use a kit for a start, even then we can assist.
My amp is broken help ! Out of the question, there are people making a living repairing stuff, go there or dispose of it
Mona
there ARE people at diyaudio who design for a living AND share "what they are comfortable sharing" in the spirit of education.
in spite of everything else, it's all good ...
and Mike's point is valid - it would be nice if the stealing was stopped.

Not to rock the boat even more, but if one wants a Tent regulator and lacks engineering expertise to design a similar device or clone it for one's personal use, then wouldn't it make sense to just order as many as are needed from Guido?
thanks Mike. To add to that, I have employees, being fed too. They have their living and spend money. This is called economy. Members of diyaudio could be employees too.
I do not patent circuits. It is expensive and only makes sense if you can run around like a policeman, or hire people who do that for you. This is not how I want to live, I prefer freedom but also know that my freedom stops where one others' starts. On the other hand I was shocked to see one of of my designs available in files, including the layout and gerbers (!), being offered at a download site...... a 100% copy.
Please understand that a design is not always new in terms of principle or idea (hence cannot be patented) but a lot of time and money goes into making it robust, applicable, fool proof, produceable and so on. Not to mention the measurement equipment that needs to be bought and maintained. A lot of equipment is developed in house (jitter meter, sub LF nV meter, low noise pre amp) which is time consuming. Needless to say that copycats don't need this at all since they are totally ignorant of what they are doing so why measure anyway.
If I would have stayed within Philips (my former employer till 2005), I would have made more money, but it surely was less fun.
To me it is important to share knowledge. A community will grow because people share. To learn means to invest, in yourself. To Raul_77 I'd like to say; start with the basics, with ohms law, voltages and currents. That is a first requirement in order to get the right answer on your question. Without specifying what you need, no-one can answer you correctly. Once you pose the right questions, you'll get better answers, which, in turn, will bring you further.
We are all standing on the shoulders of our forefathers.
all the best,
Perhaps it's in your old eyes 😀 Tryed it ?
I am old too, someone simulated it (with a BJT, not the darlinton) for me, works fine.
Mona
What exactly makes you think that it doesn't work?
It's better than many designs that have been published at this place.... (i speak about the basic schematic).
😀
Going back 10-14 years, look how helpful he and also Fred Dieckmann, Charles Hansen, and others, were with DIY'ers. Sometimes harsh in the use of words (contrary to the always polite Mr. Pass), but it was possible to learn.
I was too late to the party, and would have liked to be here at that time.
That were the times that must have rocked, I found out while discovering old threads.
Less kits, less spoon feeding, more (and better) hints at why something might work or not. And more humour, I have the impression.
All banned, retired and whatnot.
indeed.
there is A LOT of valuable info that can be learned from those old threads.
regarding harshness in folks who try teach others, "MY" academic experience has often been the ones who applied the biggest boots to my rear end saw potential in me they didn't want me to waste. that thinking tempers my view on the interchanges here. having been at diyaudio for a while, i have often seen that suggestions that should be translated along the lines of "spend a few bucks to buy a used copy of AoE and do some reading, then come back with questions. it will serve you well in the long run." is not always received well.

If the OP had asked;
What is important
Here is a schematic can we talk
Why was this done
Guido, why did you do this?
And on and on and on...
But he asked for the schematic of a commercial product of a member here in good standing for the purpose of knocking it off. Two totally different things. And it got my blood pressure up. There is no learning then.
I get the "I want to buy a kit because I can't/don't want to design something." But then buy the kit. Tent's products are not that expensive.

I haven't replied for a while but now I feel the urge to reply because my bloodpressure rises. It seems that you haven't read my posts carefully. So again when I've asked this question I wasn't sure if this design is free so I added that in this case I asked for an alternative. And as a Student 35-40 bucks (€) for ONE reg is not very cheap. I understand the point that Guido needs to pay his bill but I can't afford it. So I don't use his design (don't have the layout) now I'm using a self designed parallel lt3042 LDO circuit deadbugged.
I also added that I prefer opensource. From closed Design it is not possible to learn even to guess it superior design points without operating in grey fields of legislation.
I check any Design before I use it. Im a Masters student in Physics so analyzing everything is my nature. After my own analyze I start ask questions - because I don't want to bother anyone with stupid questions like "why is it good?". So now you might understand my initial thoughts. If you comment my question please read all my replies first. Thanks.
OK, you are a student. Then you should have the creativity to search and find some open source shunt regulator design; there must be several, and for learning reasons you already preferred to go that way.
The same time you would not provoke irritations by putting ready built and commercially available shunt regs into the mix. Seems not to be that difficult IMO.
