I’ve been lucky to go to a series of Paper Circuits Club meetings with Jie Qi (the researcher who PLIX co-designed the Paper Circuits activity with, based very heavily on her art and ongoing work) and Natalie Freed. They now work together at Chibitronics.
Thank you for sharing this comparison of different LEDs. So helpful to learn more about resistors and why the blue LEDs don’t “play nice” with the other colors. I the Chibitronics stickers!..makes me want to do some more tinkering with paper circuits.
