^Video of how it works!
I decided on concept for this no-hands switch inspired by the Sims costume my friends did for Halloween. They had made these green crystals (they call it the Plumbob in the games) which we tied to a headband so it stays up on their heads.
Some images for reference:
I basically attached some aluminum foil to 3 sides of the crystal and that acted as the switch. Whenever 2 crystals touch each other, the LED starts lighting up.
Overall, I found it really fun to play around with the circuits. Maybe next time, instead of paper, I could use aluminium crumples to make the crystal and color it green so it is conductive from all sides and it would also look shiny as a bonus!
