I just did some searches for a smart nail and these are the results from
AliExpress and/or
Google. Apparently, Google search engine has mostly caught up with the smart nail art things, and very little about the
Jakcom smart nail. It certainly would be interesting to see how this electronics smart nail would shape up our future daily lifestyle. May be, there will be some projects you can come up with using any Jackcom smart nails on any Linux embedded system.
