Good to all,
In the end I have to do the TFG finally and as I am diabetic because I have decided to do it about this despite which Ing Informatics study :)
It occurred to me to do a survey that only has one question to develop with a clear objective a hardware device Open Source (that is, without patents) in addition to an application that will show controls, graphics and something much more interesting within the sameApp (this is the interesting thing about TFG really, and I will share it here if administrators do not consider spam when you finish it)
I leave the survey here and I thank everyone who participates and those who do not at least have read it.Thank you!
I also accept suggestions :)
