# Multi-Game Card Dealer

# 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)

# 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

Master Bus Processor

Featured Project

General Description

We will design a Master Bus Processor (MBP) for music production in home studios. The MBP will use a hybrid analog/digital approach to provide both the desirable non-linearities of analog processing and the flexibility of digital control. Our design will be less costly than other audio bus processors so that it is more accessible to our target market of home studio owners. The MBP will be unique in its low cost as well as in its incorporation of a digital hardware control system. This allows for more flexibility and more intuitive controls when compared to other products on the market.

Design Proposal

Our design would contain a core functionality with scalability in added functionality. It would be designed to fit in a 2U rack mount enclosure with distinct boards for digital and analog circuits to allow for easier unit testings and account for digital/analog interference.

The audio processing signal chain would be composed of analog processing 'blocks’--like steps in the signal chain.

The basic analog blocks we would integrate are:

Compressor/limiter modes

EQ with shelf/bell modes

Saturation with symmetrical/asymmetrical modes

Each block’s multiple modes would be controlled by a digital circuit to allow for intuitive mode selection.

The digital circuit will be responsible for:

Mode selection

Analog block sequence

DSP feedback and monitoring of each analog block (REACH GOAL)

The digital circuit will entail a series of buttons to allow the user to easily select which analog block to control and another button to allow the user to scroll between different modes and presets. Another button will allow the user to control sequence of the analog blocks. An LCD display will be used to give the user feedback of the current state of the system when scrolling and selecting particular modes.

Reach Goals

added DSP functionality such as monitoring of the analog functions

Replace Arduino boards for DSP with custom digital control boards using ATmega328 microcontrollers (same as arduino board)

Rack mounted enclosure/marketable design

System Verification

We will qualify the success of the project by how closely its processing performance matches the design intent. Since audio 'quality’ can be highly subjective, we will rely on objective metrics such as Gain Reduction (GR [dB]), Total Harmonic Distortion (THD [%]), and Noise [V] to qualify the analog processing blocks. The digital controls will be qualified by their ability to actuate the correct analog blocks consistently without causing disruptions to the signal chain or interference. Additionally, the hardware user interface will be qualified by ease of use and intuitiveness.
