Light Up (Pressure Sensing) Dragon Bookmark

In this Instructable, Emily Brooks shares her love for reading and for dragons, with a fun and flashy bookmark for the ages!

For all my fellow dragon-loving readers, this light-up bookmark is for you! Did you know that cartographers inscribed “Hic Sunt Dracones (Here Be Dragons)” in a copper globe over 500 years ago? On the back of this bookmark is a map near the edge of the Northern Hemisphere, and on the front is an aerial view of a fire-breathing dragon.

[Thanks to the New York Public Library’s public domain imagery for the map near the edge of the Northern Hemisphere on the copper Hunt-Lenox globe https://digitalcollections.nypl.org/items/16891d60-66fc-0133-fbd6-00505686a51c ]

Print the PDF on black card stock with a black toner printer. Do not use inkjet!

For demo purposes, this image depicts the PDF printed upon gray paper. I suggest you print the design upon black card stock.

Use non-permanent tape to attach metallic toner-reactive foil to the printed side of the card stock.

Run the foil/ card stock sheet through a thermal laminator twice.

Peel the foil from the card stock.

Use a craft blade to cut around the edge of the bookmark as well as the inside of the flame.

Use conductive fabric tape, a coin cell battery, and the red, orange, and yellow circuit sticker LEDs to create the circuit on the inside of the bookmark, leaving a gap as seen in the image.

Tape a small strip of pressure sensitive conductive plastic to the other inside of the bookmark to allow the circuit to complete when pressed.

Tape a strip of vellum behind the flame cut out to diffuse the light.

Tape the bookmark shut.
