This week, we started and completed our research on the subject of holograms. Furthermore, we also made a mock-up of the holographic device used for our project. First and foremost, we decided to only use cardboard pieces to build our prototype because it was a cheap and simple way to do so. It was also created as a potential reference to the construction of our final iteration. To build this cardboard mock-up, we first cut out 4 triangular pieces. We then put them together with tape glued all four pieces with hot glue. Finally, a final square piece was attached to the tip of the pyramid. During our 2 days of prototype building, we did ran into some minor problems. For instance, it was a challenge to piece together all of the facades of the pyramid for assembly. It was also hard to glue the top of the device to the rest of it, for we had to hold it in the exact spot we had designated until the glue was cooled. In the end, however, we were successful in our attempt to build a prototype for our project. Next week, we plan to present the prototype and to try our holographic device in a much smaller scale first before attempting to build a larger version of it. We will also try to make a holographic picture suited for a holographic experience.
