This is a great activity because you can use materials that you have around your house or you can use extremely inexpensive materials that make the circuits flat and easier to work with.
What you’ll need for the circuit:
– A conductor
The easiest thing to use for the conductor is copper tape. It is flexible, flat, and has a sticky side, which makes it optimal for a card. You can purchase copper tape online easily for a couple of dollars. If you don’t want to buy something new and have thin copper wire lying around you could easily use that, it would just require more tape
In the making of my card with the dog I used the classic big old leds because we had some lying around. You can get those in bulk online easily for a couple dollars as well. If you want to make your card more streamlined, and able to be put in an envelope you can use special small leds as you can see on the heart shaped card in the intro. The second image in this step shows a strip of those tiny leds. The tiny leds are a bit harder to work with.
– A battery
The battery that I used is the CR2016 3V because it has the required power and is thin. However you could use any batteries lying around as long as they provide enough voltage for the led and you don’t mind some bulk. You can purchase a 5 pack of these online for a couple of dollars.
What you’ll need for the card:
Both to make the card and to cover the circuit. I used colored and white paper.
– Glue stick
I used electrical tape.
– Other crafty things
glitter, stickers, buttons, etc.
