Problem:

Poker is one of the many card games that requires multiple components, such as a deck of cards and some type of chip system in order to keep track of money, in order to be successfully played. While most poker games are planned beforehand, there may be some unforeseen change of circumstances, such as extra players joining or a lack of chips among many others. This could create problems and cause players to make unwanted adjustments to their game.

Solution Overview:

Our solution is to create an electronic money and betting system that will serve as the main interface for keeping track of your current money, as well as adding to, or subtracting from, your current total. Within the game of poker, this solution allows the user to use this as a substitute to physical chips, enabling a larger space (no chips to occupy space on the table) for additional players to play, as well as not having the need to redistribute the already limited amount of chips if more players want to join.

Solution Components:

Controller Unit: Maintaining data, and doing arithmetic computations on it. We envision this to be able to do tasks such as raising a placed bet, adding and subtracting from a players total, allowing buy-ins, auto-splitting the values of the coins etc.

Processor Unit: Microcontroller for signal processing between RFID reader and control unit (can use Raspberry Pi)
RFID reader (RC522) to process the RFID card (using RFID MIFARE 1k chip)

The intention behind this is to have a way to identify which player’s turn it is to properly display and add/subtract their chips from their respective pile.

Power Unit: DIY portable solution to power the Raspberry Pi

Display Unit: We are planning to integrate the potential use of an LED display, but we are still considering other alternatives to this.

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
