It seems that virtual reality glasses and headsets are catching on. Although we currently do not have any type of free hardware that gives us similar results, we can use the known to build it. A) Yes, a user named Victorjung has shown on the Adafruit twitter account a curious model that collects Google glasses but built with a 3D printer.
The glasses to which we refer are called the Google Cardboard, glasses that are built with cardboard and adapted to insert any smartphone with Android and that serves as a screen to show us the applications in virtual reality, thus you get virtual reality glasses for very little money since the smartphone is in charge of producing the sound and the image.
In this case, Victorjung has created a Google Cardboard design adapted for the Nexus 5, which to date is the best-selling and most used Google smartphone on the market. Although this limitation is not so much since any smartphone with a 5 ″ screen can be used, although there may be some complication with some model.
The Google Cardboards have been designed and printed by an Adafruit user
The best thing is that all the files of this printed model of the Cardboard are totally liberated so we can build one of these glasses with our 3D printer and in a short time have virtual reality glasses that work with our smartphone.
In addition, we can also make our own modifications as if it were cardboard glasses, so there is no reason to have virtual reality glasses. Of course, they will not be the Morpheus glasses for our game console but they will be good glasses to have some virtual reality, don't you think?
