Today
You will learn what makes a circuit work and apply this to create/make something novel and unique.
You will apply the engineering design process you’ve practiced in school on today’s design task.
Basic Circuits
Circuit → Circle
+`
Light Emitting Diodes (LEDs)
LEDs (Light Emitting Diodes) are simple, low-cost semiconductor devices that produce light when voltage is applied in the correct polarity.
Modifications to the LED
Using Copper Tape on Paper
Copper Tape is Conductive...but sticky stuff isn’t!!!
Try to use one continuous piece of tape for each section (grey parts).
Fold, crease through each corner.
Or - make sure shiny part is touching shiny.
Adhesive is non-conductive…Making Corners with one piece of tape
Try to keep the piece of tape continuous across corners and through-out the circuit.
FOLDFOLD FORWARD to CREASE(Sticky side exposed)
DONE!
FOLD DIAGONAL TO MAKE A CORNER
But, what about when you run out of tape??Joining Traces
Joining by touching the SHINY-SIDE to the SHINY-SIDE of each section. Secure with Clear Tape.
FOLD BACK FOLD
1/2 AGAIN
BREAK
JOINING PIECE
Overlap Shiny-side to Shiny-
side
We said copper tape is conductive, but the sticky stuff is not.
Define the word conductive.
A few definitions...
The flap is down, and shiny is touching shiny. This is called a closed circuit.
And a few more...
This is called an open-circuit.
Define “open-circuit”
The flap is up.

A few template ideasPull-Tab Switch

How else can you make a switch?
A little inspiration??
Draw, sketch, make something unique!Your turn...
Design ProcessProblem Statement
Design ProcessPlanning….Sketch, write, doodle… think about the following:
•WHO IS IT FOR?•WHAT SHOULD IT DO?•WHAT SHOULD IT LOOK LIKE?
Phase II -- Adding pop-up Paper Engineering to Paper Circuits
Pop-up CutsV-Mouth Cut
Place a dot near the center of the new rectangle.
Draw a perpendicular line to the folded edge of the cardstock.
Folded Edge
Pop-up CutsV-Mouth Cut
Cut along the line to the dot.
Folded Edge
Pop-up CutsV-Mouth Cut
Fold the right-hand side to form a triangular flap and crease.
Flip the card over and crease the triangle over on the other side as well.
Pop-up CutsV-Mouth Cut
Repeat for the left flap. Fold the left-hand side to form a triangular flap and crease.
Flip the card over and crease the triangle over on the other side.
Opening the Mouth
Open the card up like a tent.
Using your thumb or fingers, push the top triangle and bottom triangle through to the inside.
Finally
Close the card and press firmly.Re-open to work the mouth-action.
Variations? What other ideas do you have? Add LEDs, switches, push buttons...

Draw a jagged line instead of a straight one and you have a mouth with teeth!
