Create an awesome Valentine's Day card with this DIY project!
This card will surely bring a smile to the face of any die-hard Zelda gamer and showcases a fun way for beginners to make a unique DIY gift using simple items and cool electronics. You can really get creative by using strips of copper foil tape, a standard red LED
, and a CR2032 coin cell
like we are going to show you in today's blog.
Building the Card
Cut out the red construction paper measuring at 5" (L) x 10" (W) and fold it in half as the base of your card.
Cut two pieces of white posterboard to 5" (L) x 4.5" (W)
Feel free to choose your own dimensions for your card. We went with the standard card size for ease of delivery but the electronics can be scaled to fit almost any card size.
Save the pixel heart from the link here
and print it to the desired size. To produce the sizing in the image above, we opened the image in Microsoft Word and sized it to 3.5" by 3.5". You may want to print multiple per page so you have extra ones on hand if anything goes wrong.
Cut around the pixel heart and glue it to the center of one of the pieces of white poster paper.
We found this cool pixel speech bubble generator online and used it to generate the text for our card. Use the link here
and type (without the quotation marks):
TO GO ALONE!
Space out the text in 3 lines (by default it will be on one line) and print out a couple text bubbles in the same method as we used for the heart. Cut out one of the bubbles and glue it to the center of the other piece of white poster paper.
Once this is done the poster paper with the speech bubble can be glued on top of the red construction paper (Use the picture above as a reference), while the other poster paper with the pixel heart is left aside.
Adding the Electronics
Test the LED bulb with your coin cell, one wire should be longer. Make note of the polarities and bend the wires flat.
Take the LED
and trace the diameter of it in the center of the heart glued to the poster paper. Carefully use a scalpel if you have one or a knife to carefully cut out the traced hole. Make sure to cut from the top down so that any scrap paper is on the backside of the poster paper.
This is what it should look like once the LED has been inserted into the poster paper.
We are now going to create the circuit that will live behind the heart and white poster paper!
Take the CR2032 coin cell
and trace a spot on the bottom right corner of the card. Be careful about the placement of this circuitry as the white poster paper must cover all of it when you are finished. Find a location for the press button and create a basic outline for the copper foil tape. Don’t worry if it's messy as it will all be hidden eventually.
Place the copper foil tape on the outline and leave a small gap between the pieces of foil for where your "press here" button will live (bottom left corner). Be careful not to extend the foil past the boundary of where the white poster paper will sit.
Use scotch tape to make a ring, and tape the top of the white poster paper down, leaving the rest of the paper unaffixed. With the bottom half opened, tape the positive and negative wires of the LED to the copper foil circuit to complete the connection. Lastly, use a small piece of copper foil tape affixed to the underside of the left corner of the white poster paper.
Bend the left corner card up slightly so it doesn't complete the circuit and then press the card down to test the circuit and make sure the LED lights up.
If the LED does not illuminate when the circuit has been completed when pressing the "button", we recommend checking the polarity of your LED, the connection of the foil to your coin cell, and also the connection of your LED legs to the copper foil circuit. You can always use a multimeter to check the continuity of your circuit to make sure everything is connected.
Once you test that the circuit works, add some creative flair to the card and get decorating! If you decide to DIY this project, drop us an email at firstname.lastname@example.org so we can feature your results!
