Vertical Holographic Box for Smartphones

thingiverse

Just created my own vertical Holobox for Smartphones, based on Pepper's ghost illusion technique. Perfect for showcasing products! Simply slide the acrylic glass sheet into place and position your smartphone on top. High-contrast images, animations, videos, and more that have a black background work exceptionally well. On your smartphone, turn off automatic brightness and adjust the slider to maximum brightness. This version is optimized for vertical product presentations, which means your videos need to be oriented vertically at 1080px x 1920px resolution. Best suited for showcasing long objects. For optimal results, you'll need a special holographic reflective film. Attach it to a piece of acrylic glass using water and dish soap. With this foil, you'll get the best results because it also reduces double reflections caused by the 2mm thick acrylic glass. The foil resembles a one-way mirror film but is not too reflective. Unfortunately, I couldn't find it on AliExpress, so I ordered directly from Defi-Tech: http://www.defi-tech.com/holo-film-for-showcase.html If you know of any alternatives, please let me know. You can also use just the acrylic glass, but you'll notice a visible double reflection in your projection. However, a piece of DIN A4 transparent film for laser printers works well too, especially in dark environments, as it eliminates double reflections. In daylight, though, the projection will appear pale and lack contrast due to the absence of a reflective coating. If you have any ideas on different foils that might work, please share. The acrylic glass sheet measures 153mm x 71mm x 2mm. Note: The pictures were taken with the special reflective film attached to the acrylic glass sheet, except for the fireball in the dark environment, which was captured using a transparent film for laser printers. Check out the video to see how it looks like. The first clip features the green PCB and was created with the special reflective film. The second clip uses only a piece of transparent film for laser printers in a dark environment: https://youtu.be/tIJAf9W8blQ
