What You'll Need
Teknikio Ghost LEDboard,
Paper and cardboard
Scissors, Soft Tape, Glue
Plan out your circuit
Plan out your circuit using alligator clips. Connect the negative and positive pads of the Ghost LEDboard accordingly to the Batteryboard. Your Batteryboard should have two connections like the picture.
Create the frame
To make the frame, cut and score the cardboard according to the template in to your preferred size.
Create the screen
Cut a piece of copy paper just a little bit bigger than the opening on the frame, then fold in half and glue the long edge. Now you have a little envelope for your secret message.
Glue the frame together
Glue the envelope you just made onto the back of the frame, covering the opening you cut out off the cardboard frame at the beginning.
Assemble the frame
Assemble the frame by folding and gluing the sides, creating a box.
Write your secret message
Cut another piece of paper, such that it will fit inside the screen. Write your secret message, preferably with a bold pen/marker.
Create the light stick
Place the LED and battery on opposite sides of the popsicle stick.
Using conductive tape, connect the positive pad of the LED onto the positive side of the battery which is marked with a + and the negative pad to the negative side of the battery which is the embossed side.
Make sure that the 2 tape pieces don’t touch each other. Now your light stick should light up!
Test it out
Use the light stick you just created, you can now reveal the secret message you wrote earlier by guiding the light stick to light up certain area of the screen! Change the messages anytime you want.
