Step 1: What you need:
2- cardboard storage boxes. (16 x 12 x 12)
1 - any computer with a bright monitor that can run a web browser.
1 - mirror that will fit in the storage box. (mine was from the Dollar store).
1 - glass or plastic pane that will fit in the storage box. (mine was from an old scanner).
1 - extra box to prop up teleprompter if necessary.
Stand or table that will be a viewing height. (We used a cheap ironing table from goodwill.)
Stand to adjust mirror angle (i.e .http://www.instructables.com/id/Ipad-et-al-holder/ )
Box cutter or knife.
Step 2: Assemble the boxes
Note: Since you are going to cut out part of the box, you only need to glue where it will not be cut out.
Put the top box on top of the bottom box so the open side panels are in opposite directions
Tape the two boxes together at the center.
Step 4: Putting it together.
Open top box and insert glass at 45 degree angle.
Camera should be in top box behind glass. (i put mine in an envelope glued to the back of the box.
