I've become very interested in 'phygital' and came up with the idea to create a holograph that I could mail to potential employers. The goal of this project is to create physical hologram screen and digital content to go along with it. The physical components need to be small, light and easy to assemble. The final product will be packaged in a small cardboard box with assembly instructions inside.
My first prototype was created using plastic from a CD case and held together with tape. This original prototype showed the image well but the plastic was very flimsy to work with and very easy to scratch. I switched to using thin acrylic sheets which are more durable but harder to cut. Cutting the required shapes by hand did work, but the shapes were more uneven and the process was time-consuming. Cutting the acrylic with a band saw is much more efficient and accurate but leaves tiny chips on the edges.
Once I had four more or less identical acrylic pieces I moved on to creating a base. A friend and I co-designed the shape of the base then my friend created the 3D model on SolidWorks.
Our first base (pictured far left) was too large, it cut off the image on smaller phone screens. Our second base (pictured right) was much more successful and proved easier to assemble with the addition of an elevated center to help grip the base when assembling the hologram.
The smaller base had one catch to it. On larger cellphones the sound vibrations moved the hologram hardware across the screen. This issue was resolved by attaching a thin rubber layer across the bottom of the base to increase friction.
