System Integration
The DIS-CARD project is to distribute playing cards among players for various card games such as UNO, poker, etc. The device accepts input for the number of players and the number of cards per player, and then automatically distributes the cards accordingly.
After sketching, I listed out the highlighted features of my project as well as its possible production methods
Features of DIS-CARD
- Automated Card Distribution:
- User-Friendly Interface:
- Cost-Effective:
- Customizable:
- Efficient Mechanisms:
- Adaptability:
- Easy Assembly and Maintenance:
- Future Expandability:
Production Method
- Laser Cutting: For precise cutting of components.
- 3D Printing: For creating custom parts and housing.
- Circuit Designing: Creating the electronic circuit layouts.
