I have a project that I would like to retain copyright over conceptually while releasing the prototype code. It's a novelty digital clock. I posted some videos of the prototype online and some people asked for the code.
I don't really care about protecting the technology within the code as any half decent programmer could work that out pretty easily. And I have no problem with people recreating the project as long as they don't start selling it. It's mostly about preventing anyone from stealing the idea and / or design to sell it.
So do I even need to license the code, assuming that copyright law will protect me from that?
