It's a fun project!
Step 1: Thermochromic Ink
I use the thermochromic ink to paint to each card
The mixture are
- Thermochromic Ink powder (20 g)
- Fabric Glue
Step 2: The Heat Pad
I use the circuit done above and plugin with the 9v Battery to get my conductive thread heat up :)
The white dashed line is the conductive thread the black is ground and the red one is the power!
Step 3: AR App
the AR app was done by Unity using Vuforia to make it happen.
This is a series of the AR tutorial I watch to get it working :)
Step 4: Demo Video
The video shows the process and how to play with the cards
