Holography is a subject that was long forgotten but it seems to have returned and stronger than ever. Several maker users of the Hackers House group have developed a project for a holographic monitor, a holographic box that is far from what we have known so far and that can be controlled by hand gestures.
This box may well be a small reproduction of what could be a large screen holographic monitor, but so far no one has said anything about the matter and Hackers House may just keep this little monitor.
The best thing about it is that we do not need to pay any company or depend on proprietary software since everything has been built with hardware libre and reused parts. Wood has been used to build the structure; to recreate the image, the creators have used the screen of an LED monitor; a Raspberry Pi 3 has been used to manage everything and to create the holography, a glass pyramid has been used. The software for this holographic monitor is based on Raspbian and Node.js, something that is available on the Internet for free.
This project does not use usual controls but has a small gesture screen that allows the user to control the image by gestures, this is the most expensive part and difficult to achieve for some, but it can be replaced by a traditional remote control. Everything can be done and modified thanks to the build guide It is public, that is, the Hackers House group has published all the documentation in a public repository. So that we can make any modification and even reproduce it on a large scale, creating a holographic monitor like the ones that appeared in science fiction movies. And you Do you dare to build a holographic monitor?
