Applications and Implications
- Individual assignment: Propose a final project masterpiece that integrates the range of units covered
What will do?
My final project pretends to read trading card game cards and send the name of the card to a Database.
Who has done what beforehand
Michael Portera made a Magic the Gathering and posted on Hackster.io webpage. His model uses legos to build the housing, a Raspberry and a Raspeberry camera.
Another work came from Joao Almeida (starstuffharvestingstarlight in github). Uses OpenCV and Tesseract for OCR recognition.
What will you design?
My work will consist in programming the Raspberry Pi to detect a TCG card name. To achieve a good capture, I will place LEDs to make the card brigther on each take. A board for this LEDs will be solded. Finally a 3D Printed housing will encapsulate everything.
What materials and components will be used?
| # | Piece | Quantity |
|---|---|---|
| 1 | Raspberry Pi | 1 |
| 2 | WebCAM | 1 |
| 3 | Wires | 10 |
| 4 | LED | 5 |
| 5 | Resistor 499 | 5 |
| 6 | Attiny45 Microprocessor | 1 |
| 7 | MDF | 1 |
| 8 | 3D Print Filament | 1 |
| 9 | Electronics board substrate | 1 |
Where will they come from?
3D Printed house and board elements will come from the FAB inventory. Raspberry Pi, wires, and the camera will be bought from local vendors.
How much will it cost?
I will be using FabFoundation price list and local vendors price as reference:
| Part | Qty | Unit Price | Sub-Total |
|---|---|---|---|
| Raspberry Pi | 1 | 100$ | 100$ |
| WebCAM | 1 | 30$ | 30$ |
| Wires | 10 | 0.1$ | 1$ |
| LED | 5 | 0.15$ | 0.75$ |
| 499 Resistor | 5 | 0.01$ | 0.05$ |
| Attiny Microprocessor | 1 | 1.06$ | 1.06$ |
| Filament | Aprox 50gr | 42.00$ | 2.10$ |
| MDF | Aprox 0.5m2 | 1.70$ | 0.85$ |
| Substrate | Aprox 0.02m2 | 1.4$ | 0.03$ |
| Total | 135.84$ |
What parts and systems will be made?
- Part - Housing
- Systems - LED board
What process will be used?
| Part | Process | Materials |
|---|---|---|
| Housing | 3D Design and Laser Cutting | 3mm MDF |
| CAM Holder | 3D Design and 3D Printed | ABS Filament |
| Electronics | Electronics Design, CNC Routing, Electronics production, programming | Substrate and components |
| GUI | GUI interface and programming | Python code |
| Assemble | Packing |
What questions need to be answered?
Questions like:
- There is enough light for the camera to get the card name correctly?
- It is sending data correctly?
- Could it work with only USB cable?
How will it be evaluated?
The project will be evaluated using real Magic the Gathering cards. Cards will be scanned one by one, and all data will be sent to an Excel sheet. It is important to notice the TCG Scanner only needs to scan card's name. Other text should be avoided.
