Creating a pop-up circuit card is a fun way to learn about circuits, elasticity, and a material’s strengths and weaknesses
Visit http://pbskids.org/designsquad/build/string-puppet... where we learned how to make one without a circuit.
Materials List: (Most of these supplies can be purchased on amazon.com and joanne.com)
- Card stock paper, variety of colors
- Paper scraps and arts and crafts bits for decorating
- Pencils, Markers, colored pencils etc.
- Hole punch
- Drinking straws
- Smoothie/Bubble Tea straws
- Fishing line (we bought south bend 50 lb monofilament on amazon.com)
- 5mm LEDS
- Cr2032 lithium 3 volt batteries
- Thin conductive wire, we used 26 gaugePanacea Corp florist wire from Joanne.com (even the kid scissors cut it and it is soft and pliable)
Step 1: The Design
Step 2: Choosing an LED
Step 3: Putting the LED Through Your Design
Step 4: Flatten the LED Legs
Step 5: The Wire
Step 6: Attaching the Neck Straw
Step 7: Making the Arms
Step 9: Animating the Arms
Step 10: Attaching the First Arm Into the Body
Put one of the straw arms through the bubble straw. The nylon line should come out of the bottom of the bubble straw.
Step 11: Finishing the Arms
When you get them the way you want them tape the connection.
Step 12: Taping Down the Negative Wire
Have it move over to the front of the straw and end the taping about 2 inches from the bottom of the bubble straw.
Step 13: The Aluminum Foil
Cut off any extra positive wire and tape the top of the aluminum foil to the bubble straw. Try not to get too much tape on the aluminum foil so you have a lot of room for the switch to make contact.
Time for a test run. Rest the positive side of the battery on the aluminum foil and the negative wire on the negative side of the battery. Hope your light comes on otherwise recheck your work for a loose connection or a place where positive and negative are touching creating a short circuit.
Step 14: Making the Battery Pack
Fold the piece in half. Use a hole punch to make approx. a ½” by ½” hole.
Tape the sides of the battery holder to turn it into a pouch, leave the top open and don’t cover up the hole with tape.
Step 15: Attaching the Battery Pack
Tape the negative curled wire to the negative side of the battery.
Slip the battery pack onto the battery and make sure the plus side is showing in the hole. Tape it down to the straw.
Make sure the negative wire is not touching any of the aluminum or you will get a short circuit.
Now try it out. Push the battery pack/switch to light up your puppet. Pull the nylon lines to animate the arms
