The OP has this idea to build an open source tool called "The Station".

The OP has almost zero knowledge about how to develop "The Station" and as such he is now searching for horses to put in front of his cart. As a reward for your sweat and hard work your name will be mentioned on the webpage of the open source product.

Maybe I'm wrong (my beard starts to be grey) but I don't think that's how the world works and I find this very impolite and rude. Anyway I'm going to take care of my open sores.

Please read the profile of people before insulting them, I'm a woman !
Ps) I don't know what perks you expect on an open source project, with no lucrative goal,
I can offer to pay the long-term contributors the same as me and my dev.
I just want to say it's a collaborative project, my goal is not to become popular from it, it's just to offer to the community, a good product long lasting easy to repair and upgrade.

Everything you wrote is beyond the comprehension level of the OP. If you would read what he posted, you would know that the OP can't read what you posted. I also don't think this is an "asking for help" post.

Here is an excerpt from the first attempt at finding horses.

https://www.eevblog.com/forum/oshw/the-station/msg5623197/#msg5623197

This project is open source, and is not for profit, the goal is to offer the best products for the best price and having it durable, and reparable.
Every one participating in the project will be thanks In the website for the project's (you will be able to include your website)
In the first time the product will be available on AliExpress with free shipping (I will use already implanted Shop I will just take a small cut to pay me for the price of the prototyping (the shop will receive a badge certifying they are contributing to the project but especially that the kit is conform to the original design and functions). For the price and the ease of shipping. (Better price for the customer)
I a second time I hope to get it available in European Shop will be obviously more expensive but you will get 2 years of warranty and a more rapid shipping.

I don't know what others make of this.

Thanks
A lots of things to learn, but also I understand the majority of what you explains, obviously apply it on a circuit is way more complicated.
I'm happy you take the time to explain the difference, and the circuits aren't the same between the different types.
And yes I'm sure this can be interesting for others person because gan is still a new technology for the power supply (it should also be cheaper in the future because it's more simple to produce than the other type > https://community.element14.com/products/manufacturers/wuerth-elektronik/b/blog/posts/gallium-nitride-vs-silicon-in-soft-switching-comparative-study.

I don't think OP is trying to be impolite or take advantage of people, I think they're just wildly underestimating the complexity of their endeavor, since I don't think they're very experienced. They don't yet know enough to realize all the things they don't know, but need to for this project. I get it, I've been there before (but luckily had people to help me reign that in and guide it towards something doable).

Op know it's a very complicated project, but she also knows it not that complicated if the community help.
Because everyone can't know everything, but multiple people with different capacity can do a lot of things.
Don't worry I still have a lot of work in the background for this project, I will also have a website (I don't give the name for now because it's complicated to find a good domain name available what I have found. The website is for the resources for my different projects (No Ad or tracking Cookie).

My apology on that part.

What do you and the dev expect in return? Nothing? You are willing to spend multi K euro's on a project and many days, nights, evenings, weekends,... and in the end live in a carton box while shops are distributing the station which some companies produce for one tenth of the price you would pay?

I expect at least three honorable mentions in a well known magazines so I can decorate my carton box.
 

Op know it's a very complicated project, but she also knows it not that complicated if the community help.

I think you and the dev must have a conversation with she.

I think you and the dev must have a conversation with she.

Is that really necessary? If you think it's impractical or over-ambitious, then after you've stated that, why not leave it be and try to live up to your username.

I don't have any comment on this discussion, but just reading, it paints a lot of non-engineering-related, and actually sexist, negativity as a picture, for anyone who reads the thread, when you respond like that. It's not professional.

[coppercone2]

you need to renegotiate your salary if a few K project makes you live in a carton as a engineer.

who is gonna pony up and buy the first GaNFET?

I don't know about sexist tendencies here. However it does a bit concerning to let someone who admit themself having no/little experience in power supplies or electronics in general suddenly jumping to make wide range dual control variable SMPS, probably mains powered too.

Actually they aren't -- they are HEMTs.

Of course if you look closely at them they are different. But looking at application level there aren't that much difference. At least not to the point that you need a new topology, for both the supply itself or the control/drive.

I don't know about sexist tendencies here.

Why are you making excuses for it? That sentence from temperance was completely unnecessary, and not on. What's that sentence got to do with sharing a concern about lack of experience in working with mains equipment?

And for the record, even first-year undergrads often end up having to build a mains-operated power supply, under supervision.

I do some electronics for more than 10 years, and I watch electronic/engineering for more than ten years  (yeah some people watch tictoc or the Tv)
So thanks to underestimate me, yeah I have some difficulties, but the electronic in general have some difficult points to understand.

An illeism is the use of the third person in reference to oneself and, in this case, used to convey a sense of objectivity. In any case what I said is not meant as sexist. The third person could be "he" as well.

An open source power supply:

This has taken some years to develop. Maybe two or three.

An open source soldering station:

All the best.
