Hi! A friend of mine has a hardware project, and he was wondering what licence to use for it. As you probably know, most DIY hardware doesn't really specify any licence, just some vague handwaving like "as long as you don't make a lot of money off it, it's OK." So we were fighting about differences between open and closed ways of doing things. He wants to make the whole thing as free as possible, but he doesn't want other people to make a profit from his work either. So at some point I said: "Hey, let's look at the uCapps projects, they're completely free, yet no-one is ripping off their stuff and making lots of money! There's only a couple of places selling kits." So I read the FAQ here and searched the forum, and... Surprise surprise, there's a LOT of hand-waving going on here too! :-( From the FAQ: "As everything is free, am I allowed to bring the stuff to market?" "Every MIOS application is licensed under GNU GPL (http://www.gnu.org/copyleft/gpl.html), you are allowed to distribute the application, and you will be the copyright owner of your own code (but not of MIOS itself), and you are allowed to sell your project so long you don't violate the license, and this means that you have to publish all sources (which are required to reconstruate your project) to the public domain." OK, so anyone can sell the MIOS source code. But if someone wants to "bring this stuff to market", I'm pretty sure they're talking about the hardware and everything, and not just about selling the PIC sources. If someone read only that bit from the FAQ, it would seem that anyone can build uCapps stuff for profit. But reading the forum, it seems that is not the case. In fact, Thorsten wrote somewhere that SmashTV and Mike have *exclusive rights* to making PCB's... But in another thread he said something else. From the FAQ: "All the applications of http://www.uCApps.de are non-profit projects which are not for sale." Reading the forum, it seems that you're taking this part of the FAQ to the extreme! You people actually consider it forbidden for everyone to sell these things, even single old ones on eBay! If you want to get that kind of a crazy point across, then you really need to spell it out in the FAQ. No sane person will get that from just the word "non-profit". Although I do not believe it's (legally or otherwise) possible to stop people from selling their own stuff, even if it was originally designed by you. From the FAQ: "The purpose is to follow the spirit of Open Source in order to allow people to rebuild, modify, improve or just learn from my projects." "Open Source" is a various bunch of commercial software makers' licences, most of which are more relaxed than the GPL. For example they might give everyone rights to use software as a library in a completely closed, non-free project. I'm sure for the moment it's working out great for you the way things are, but you're just heading for weird misunderstandings with potential future hardware design contributors as well as potential misuse of your designs, if you just advertise vague "GPL-style freedom" or "Open Source" on the other hand... And then they find out the deal they're contributing to is just an unspecified mess of exclusive rights, obsessive ban of profits, all of which is just made up case by case on the forum as you go along. At least that's the impression I got from the FAQ and a couple of forum searches. I'm not trolling here. I'm really sorry if it came out too offensive. I am very grateful and in big debt to everyone who has contributed to designing this stuff. And I don't want to make a profit from uCapps stuff either! I'm just saying maybe you should think about how the hardware is supposed to be licenced now, and write it out clearly somewhere on these pages. All there is now is a LOT of references to GPL or Open Source, and then a lot handwaving about how this project is "non-profit". But the GPL first of all only talks about SOFTWARE, and also it specifically doesn't say anything about "no profits", but exactly the opposite. It's a carefully thought-out licence. You can't just take it and slap "no profits" on top of it, and expect to come out with a meaningful licence. Or maybe you can, but then you have to stop calling it GPL, and you really need to write it out, and figure out all the rules and loopholes in advance. Anyway, it sounds an awful lot like you're making the classic mistake of confusing Frei Software with Kostenlos Bier, which are two completely different animals. People usually don't design hardware under a GPL-style licence, and I'm sure there's a good reason for that. The licence was designed specifically for software, and it works well for software. So I think my friend is going to use some kind of Creative Commons -licence for his hardware project. You guys should take a look at those... They are usually used for art and stuff. But they have "non-profit" licences --> Might be just what you're after!
