content: I'm in the process of making a bunch of free projects to share with other people. My intention is that others can use and/or modify my design without restriction (non-commercial or commercial), but I would like credit for the original design work.What are my options for licenses?For example, I came across the ControLeo2 Reflow oven controller. The software was open source, but what good is that without hardware, so I made a compatible PCB that I want other people to be able to use freely.You can see pics of the Reflow Ovenhttp://brianmakesit.com/I made a small Arduino Leonardo compatible board, and I think it could be useful to someone...Any advice on a license would be very much appreciated. Thanks.

content: have a look at this one also:http://www.ohwr.org/projects/cernohl/wikiCERN is releasing many quite significant designs under this, with multiple commercial producers for some boards, so it can't be that bad you'd think..

content: Thanks, I think the CERN license is a good one to use. It complies with the definition of OSHW, and that's one of my goals. It adds limited liability statements and clearly states the design is free to be used.Thanks again.

content: i did... i just posted an relevant thing, probably when people are laughing at us or whoeverotoh to the OP, try modding your china 3d printer bed, thats a nice machine, agreed with you on "too many projects thing". a shop should not be messy or not should not be debated thats just a waste of time, its personal preferences, if you want messy then messy it is. for me i love to keep my shop tidy while i can and it can get messy while i'm working on something and cannot stop for cleanup... etc etc...

content: If you release it, don't care about "commercial purposes". As with other content, this just scares possible contributors and copiers will do it anyway. Prove it in a court, of find them if you can.There's some very nice projects, but they have the no-commercial license. It makes distribution a lot more cumbersome to hobbyists and scares potential contributors because too much sense of ownership.Unless you release a big project and plan to get enough profit for a living, you shouldn't care about that. Anyway, you'll find copies out there and lawyers are expensive so prepare to profit a lotI see CERN OHL 1.2 is quite interesting, I consider it more appropiate than CC, because it's special for hardware and done by CERN.. I consider some stuff needs fixing, I would prefer one that makes the software in it to be AGPLv3+, because this can avoid TiVOization issues (open hardware, but closed because the software hides the "secret sauce")OSHWA? Their mailing list is dead, the websites of signers is dead too. They are just people into fashionable stuff with blinking lists and call themselves "artists". That Shenzhen woman at least was seen doing real soldering and have extra airbags, she at least invested in something tangible and don't pretend to be into electronics in an advanced way

content: metri,If your project includes a novel or patentable technology or concept, then be sure to choose a license such as TAPR OHL (https://www.tapr.org/ohl.html) in order to protect the novel concept from getting patented by a third party. Usually any public disclosure of something original is enough to prevent a patent by third party. However, there are hypothetical cases where a license that addresses patent issues helps to protect a open source hardware project.cheers,Ben

content: For a while, I agonized over which license I should choose for my open hardware projects. Eventually I got fed up with that, and decided to just release them with a simple notice that I'm placing the design in the public domain, without any warranty or restrictions. The last straw for me was the debate about the OSHWA certification. That's what brought me to the point of choosing to opt out of the quagmire of opinions and regulations surrounding open source licensing.I no longer care whether any particular government recognizes my license; I released the design files for you, not for them. Do whatever you want with them, or don't. If I want to release something that I created, I will, and if I don't, then I won't. I don't care whether any particular entity gives my release their own seal of approval. My shared source is my certification. I shared it, you have it, and that's good enough for me.

content: Quote from: NF6X on November 16, 2015, 06:44:31 pmNF6X, I agree with the spirit of your strategy. The only issue is one of innovation and the practice of patent trolling.If you invent something and release into public domain, a patent troll might still be able to patent and subsequently control the invention and limit progress --even interfering with your own use of your own invention.By releasing with a license, such as TAPR, a patent troll has more difficult legal hurdles to meet. If the invention docs show record of prior-art and/or you sell prototypes or kits, the hurdles are even higher.

content: publication is a bar to another party patenting an invention - in fact there are search organizations looking for obscure publications to invalidate already issued patentsI don't know how thoroughly web publication has been tested legally but the principle of publication putting something into the public domain is clear, common to all major countriesyou may have a grace period to apply yourself - but no one is supposed to be able to patent another's published idea - their patent would be invalidthat said the US Patent Office is lame, barely searches their own previously issued patents, easily misses even that prior arta few years ago a amplifier compensation scheme was patented by a 3rd party with the filing date just a month after the idea was promoted on diyAudiosubsequent discussion revealed already expired US patent prior art
