In one's life, there are 3 things you will meet: the world, the people, and your own journey. When you have seen the world, you will discover that courage and self-confidence from within your heart are the things that matter a lot. This project takes time as a horizontal axis, presenting the learning, emotions and philosophy throughout one's life, with each checkpoint lighting up once completed.
See the world: the mountains, the sea, and Mother Nature.
See the loved ones in your life: the affection, friendship, love.
See yourself: Live and learn to the end of your life.
1、 Hardware components used
3. Structural Design and Content：
4. After the laser cutting is completed, embed the hardware components and functions into the structural board.
5. The back of the board
6. The end product.
The finished product!
7. Here is a demo video of the “Life Check” board.
