Hologram Pi-ramid - My name is Automan

luislabmo

In a previous project update, I described the process of building a simple Plexiglass Pyramid essential for this project to come alive. I'm very excited now to show to my fellow readers my firsts tests of a Hologram like projection based on the Pepper's Ghost principle; it was very difficult to find proper animations of objects from different angles to show what can be done with this kind of project so I had to come with my own approach -without expending too much time in this test-.

 

While I was trying to come with some ideas I remembered the first time I learned about holograms: it was in my childhood when watching Automan an American TV series, so I took this opportunity to bring back good old memories... and well there is also a superhero.

 

Before I started creating the Hologram demos, I made a template of the areas that will be covered by the animations. Then I jumped to a video editing tool and started working in the videos using such template with a transparency to make sure every animation was within dimentions.

I then installed Raspbian with desktop, copied the edited MP4 videos to a folder and used omxplayer to run them in a loop using the following parameters:

omxplayer -b --loop --no--osd ./Automan.mp4

 

Parameters:

  • -b: An alternate to full screen mode and black background
  • --loop: Loop file
  • --no--osd: Do not display status information on screen

 

In the next steps I will be adding some black paint to the 3D printed parts  and then I will be working in the electronics.
