Holographic Home Display

This project guides the user through constructing a 3D holographic video chamber and enclosure. It employs Pepper's ghost effect and specialized holographic videos found on YouTube.

Material List

Cardboard — 20ft² (recycled)

Acrylic — 12in x 12in sheet

Small Monitor — 7 in display

• Recommendation

Speakers — small

• Recommendation

Paint — Spray Can

Tape — Roll of Packing Tape

Using recycled cardboard create two 8” x 8” squares for the base and top of the enclosure.

Using recycled cardboard create four 8” x 10” rectangles for the walls of the enclosures.

On three of the 8”x10“ rectangles cut a 7” x 3” rectangle with the base 4” from the bottom of the rectangle.

On one of the three rectangles from step 3 cut a 3” diameter circle centered 1.71” from the bottom of the rectangle. 

Cut a 1.5” x 0.125” rectangle 1” from either side and 3” from the bottom on the uncut panel from step two and the cut panel from step 4. 

On all 8” x10” panels cut a 1.5” x 0.125” rectangle 2.62” from the top edge and 3.25” from the left edge. 

Using recycled cardboard create two 9” x 2.5” rectangles and a 9” x 9” square for interior supports

Cut a 0.5” x 0.5” square out of each corner of the 9” x 2.5” rectangles

Cut a 3” x 0.48” rectangle out of each outside corner of the 9” x 9” square 

Cut a 5.45” x 5.45” square out the center of the 9” x 9” square

Assemble the 4 8”x10” rectangles around the 8” x 8” base square taping the horizontal edges

Slot in internal support structure pieces 

Tape the vertical edges and move on to creating the 3D Projection/Holographic Chamber

On a piece of 12”x12” acrylic mark out a 12” x 3” rectangle 

Using a box cutting or other razor blade-based knife cut along this line approximately 10 times 

Place the edge of the scored line against a sharp edge and while holding one side on a counter or table break the other side over

Using the other square edge of the 12” x 12 “sheet repeat steps 2 and 3 

Mark a 5.45” line from one corner of the square edge of the broken piece. 

Mark a 1.5” line on the other edge 1” from the corner used in step 5

Connect these lines together using a straight edge and repeat steps 2 and 3 to create angle breaks.

Repeat steps 5-7 three more times to create all the chamber components. 

Connect four finished pieces together to form the 3D Projection/Holographic Chamber

Paint the enclosure with black spray paint to increase contrast and user experience

Place the Speaker Inside the designated space and cut holes in the back or side to route the 3.5mm audio cable

Cut holes in the back or side to route HDMI and USB wiring for LCD and mount using cardboard standoffs in the enclosure

Place the screen into mounts created in Step 2 and route the wiring

Place 3D Projection/Holographic Chamber into top retention structure on top of the screen 

Place the top on the enclosure and secure with tape
