The main part of this project involve a hologram projector. In the beginning, we had two choices in getting a hologram projector - 1. buy one. 2. make one. It was always in my mind that we were going to make one using Fab Lab's resources, but it was worthwhile to investigate how much it would cost to buy one. At the end, I found out that it would cost 660USD plus shipping cost to get one of these below.
To figure out how to make a hologram projector, we had to understand how they work. Most online how-to-make tutorials were very basic and designed for projecting using small devices such as smart phones and tablets. Basically the hologram projector creates an optical illusion to make 2D images appear to be 3D. It is a trick to the eye. Knowing this sort of lost the magic for me, but then I released the challenge is how to make this magic trick believable.
Fellow Fab-Lab extraordinaire Nicholas Keyse works a lot with hologram projectors, and created the projection images. Nicholas suggested a few tips to produce a believable 3D hologram projection, which I would keep it to ourselves for now to save the magic.
