(Yay! So far everyday blog updates in this month!!)
As we posted yesterday, we had the second pop-ups prototyping activity in the Tinkering Studio.
I was happy to see that some High School Explainers came back after our first trial activity from last week, and continued working on their pop-ups cards. Gabriel, who was working on a switch-like mechanism last week, returned this week and made this lovely card which shows a story about an apple fallen from a tree.
(Click to enlarge) He found that the brad pin he was using last week is conductive and turned it into a switch for an LED.
Last week, we were trying to make circuits on pop-up cards to turn on LEDs using conductive tape. But that seemed like a leap for us who had not done enough basic paper pop-ups. So this week, we went back to the basic pop-ups, putting aside the idea of making circuits. And yes, making basic pop-ups itself has already very very rich content! So, adding an LED as an option seems to be better than trying everything at the same time.
Taking that into account, I made this LED holder that you can attach on your pop-up creations and light it up by simply dropping a battery.
(Led by the gravity, the battery falls to the bottom of the holder and always touches both of the LED’s legs. For paper-made switches, connecting both LED legs to the battery for sure without your finger is a hard task!)
Lighting up pop-ups adds more playfulness to this activity. By having the LED switch holders, people can start with basic pop-ups, and later on if they want they can add an LED to light up their cards. Of course, it would be better if the LED switch was integrated in the pop-up card’s natural behavior (like, when you open the card, the light turns on). But considering the richness of the paper pop-ups activity and the difficulty of making a switch mechanism and circuit on paper, I think having them separate is a good strategy for now.
I liked this pop-ups display board. Because the pop-ups working table gets caotic with papers, using a wall to show some samples is a good idea! These nice samples are from a book Karen found, The Pocket Paper Engineer Volume 1 and 2.
Hope to see further explorations next week and we’re looking forward to working with High School Explainers and summer campers!
