# Problem
Dealers are the heart of every card game imaginable. Cards must be dealt out in a certain, specific fashion both at the beginning and throughout the game. Humans are the ones who have been dealing cards for centuries, however, human error has remained a factor. Misdeals slow down setups, mess up gameplay, and ruin the card game experience for players.

# Solution

To remove errors from the dealing process, we propose an automatic card dealing machine that can act just as a human dealer with knowledge of multiple different games and rules. Our solution aims to achieve three goals:

- Eliminate misdeals from the playing card experience
- Provide validation for players that the dealt cards are fair and the playing field is level.
- Offer “human dealer” actions, such as player identification and responses to player action (such as dealing more cards, or moving on to the next player)

# Components

## Dealing subsystem
- Nema 17 Stepper Motor [Link](https://www.amazon.com/STEPPERONLINE-Stepper-Bipolar-Connector-compatible/dp/B00PNEQKC0?mcid=e981ddab58e43534b29effba82c3f107&hvocijid=1482600293604330599-B00PNEQKC0-&hvexpln=73&tag=hyprod-20&linkCode=df0&hvadid=721245378154&hvpos=&hvnetw=g&hvrand=1482600293604330599&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9022185&hvtargid=pla-2281435179978&psc=1)
- 5V Stepper Motor (ECE Supply Shop)

## Swivel subsystem
- HITEC STANDARD SERVO (E-shop)

- 5V 3A Buck (Step-down)
- 3.3V 1A Buck
- 6V–12V Adjustable Buck

# Criterion For Success
- Dealer can “simple” deal (eject one card at a time at a constant speed with perfectly even angles)
- Dealer can “real-world” deal (eject one card at a time with variable speeds depending on the distance and variable angles depending on each player's position at the table)
- Dealer can rotate 360 degrees around a pivot point and stop at different specified angles with high accuracy
- Player detection: The front camera is successfully able to detect when a player has sat down to play or got up to leave
- Deck validation: The inside camera can detect when there is a fault deck (either duplicated cards or missing cards)
- Potentially accomplished with cool ejection patterns
- Bluetooth/Wi-Fi GUI (App or external GUI) connected to the inside camera to add statistics for a better viewing experience

Assistive Chessboard

Featured Project

Problem: It can be difficult for a new player to learn chess, especially if they have no one to play with. They would have to resort to online guides which can be distracting when playing with a real board. If they have no one to play with, they would again have to resort to online games which just don't have the same feel as real boards.

Proposal: We plan to create an assistive chess board. The board will have the following features:

-The board will be able to suggest a move by lighting up the square of the move-to space and square under the piece to move.

-The board will light up valid moves when a piece is picked up and flash the placed square if it is invalid.

-We will include a chess clock for timed play with stop buttons for players to signal the end of their turn.

-The player(s) will be able to select different standard time set-ups and preferences for the help displayed by the board.

Implementation Details: The board lights will be an RGB LED under each square of the board. Each chess piece will have a magnetic base which can be detected by a magnetic field sensor under each square. Each piece will have a different strength magnet inside it to ID which piece is what (ie. 6 different magnet sizes for the 6 different types of pieces). Black and white pieces will be distinguished by the polarity of the magnets. The strength and polarity will be read by the same magnetic field sensor under each square. The lights will have different colors for the different piece that it is representing as well as for different signals (ie. An invalid move will flash red).

The chess clock will consist of a 7-segment display in the form of (h:mm:ss) and there will be 2 stop buttons, one for each side, to signal when a player’s turn is over. A third button will be featured near the clock to act as a reset button. The combination of the two stop switches and reset button will be used to select the time mode for the clock. Each side of the board will also have a two toggle-able buttons or switches to control whether move help or suggested moves should be enabled on that side of the board. The state of the decision will be shown by a lit or unlit LED light near the relevant switch.
