Pop up paper engineering - cu boulder & centaurus

  1. 1. SparkFun Electronics: Pop-up Paper Engineering http://bit.ly/CentaurusPaperEng Brian Huang Education Engineer Angela Sheehan Education Outreach Linz Craig Education Outreach
  2. 2. About us... SparkFun Electronics Boulder, CO ● Founded in 2003 by Nathan Seidle ● Focus in shortcuts to engineering design ● Design / Develop Electronics for Building, Tinkering, Making ● Rooted in Open Source Hardware Community
  3. 3. 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.
  4. 4. Basic Circuits ` + Circuit → Circle
  5. 5. 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.
  6. 6. Modifications to the LED
  7. 7. Using Copper Tape on Paper
  8. 8. 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.
  9. 9. Adhesive is non-conductive… Making Corners with one piece of tape FOLD DIAGONAL TO MAKE A CORNER FOLD FOLD FORWARD to CREASE (Sticky side exposed) DONE! Try to keep the piece of tape continuous across corners and through-out the circuit.
  10. 10. But, what about when you run out of tape?? Joining Traces Overlap Shiny-side to Shinyside BREAK FOLD BACK JOINING PIECE FOLD 1/2 AGAIN Joining by touching the SHINY-SIDE to the SHINY-SIDE of each section. Secure with Clear Tape.
  11. 11. A few definitions... We said copper tape is conductive, but the sticky stuff is not. Define the word conductive. The flap is down, and shiny is touching shiny. This is called a closed circuit.
  12. 12. And a few more... This is called an open-circuit. Define “opencircuit” The flap is up.
  13. 13. A few template ideas Push button Drawings and designs courtesy of Jie Qi at MIT Media Lab: http://hlt.media.mit.edu/?p=2505
  14. 14. A few template ideas Pull-Tab Switch Drawings and designs courtesy of Jie Qi at MIT Media Lab: http://hlt.media.mit.edu/?p=2505
  15. 15. How else can you make a switch?
  16. 16. A little inspiration??
  17. 17. Draw, sketch, make something unique! Your turn...
  18. 18. Design Process Problem Statement
  19. 19. Design Process Planning…. Sketch, write, doodle… think about the following: •WHO IS IT FOR? •WHAT SHOULD IT DO? •WHAT SHOULD IT LOOK LIKE?
  20. 20. Phase II -- Adding pop-up Paper Engineering to Paper Circuits
  21. 21. Pop-up Cuts V-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
  22. 22. Pop-up Cuts V-Mouth Cut Cut along the line to the dot. Folded Edge
  23. 23. Pop-up Cuts V-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.
  24. 24. Pop-up Cuts V-Mouth Cut Repeat for the left flap. Fold the lefthand side to form a triangular flap and crease. Flip the card over and crease the triangle over on the other side.
  25. 25. 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.
  26. 26. Finally Close the card and press firmly. Re-open to work the mouth-action.
  27. 27. 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! Concepts, images, and credit to Robert Sabuda: http://wp.robertsabuda.com/how-to-make-a-v-fold-mouth-pop-up/
  28. 28. Resources, Credits, and Thank yous Thank you to Jie Qi and the High-Low Tech Lab at MIT for the concepts, designs, and artwork for these paper circuits. Thank you to Robert Sabuda for his pivotal work in pop-up books and pop-up art. Full-scale templates can be downloaded as a PowerPoint file here.
