After a lot of time thinking about this sad story, I decided to release the project to public domain. I won't sell it and I won't make any real money with it, so in my opinion, this is the best option : with a strong license, it should prevent any fishy corporation / administration to exploit it, still allowing users to do whatever they want with it.

So I'm left with 2 questions for the Hackaday readers :

- what would be the best license to use ? I want the device to be free (as in freedom), but I don't want nasty corporations to use it for bad purposes, locking it to the public or make insane money with it (it would not be fair in my opinion)

- is asking for a donation a bad idea ? Would you give one ? I think getting some money back would be fair, as I lost so much designing a useful tool I'm now willing to give for free.

Do you have a better idea ?

I still want to write about the story surrounding this project : we often read about successful stories, failures not so much...
