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.

Low Cost Myoelectric Prosthetic Hand

Featured Project

According to the WHO, 80% of amputees are in developing nations, and less than 3% of that 80% have access to rehabilitative care. In a study by Heidi Witteveen, “the lack of sensory feedback was indicated as one of the major factors of prosthesis abandonment.” A low cost myoelectric prosthetic hand interfaced with a sensory substitution system returns functionality, increases the availability to amputees, and provides users with sensory feedback.

We will work with Aadeel Akhtar to develop a new iteration of his open source, low cost, myoelectric prosthetic hand. The current revision uses eight EMG channels, with sensors placed on the residual limb. A microcontroller communicates with an ADC, runs a classifier to determine the user’s type of grip, and controls motors in the hand achieving desired grips at predetermined velocities.

As requested by Aadeel, the socket and hand will operate independently using separate microcontrollers and interface with each other, providing modularity and customizability. The microcontroller in the socket will interface with the ADC and run the grip classifier, which will be expanded so finger velocities correspond to the amplitude of the user’s muscle activity. The hand microcontroller controls the motors and receives grip and velocity commands. Contact reflexes will be added via pressure sensors in fingertips, adjusting grip strength and velocity. The hand microcontroller will interface with existing sensory substitution systems using the pressure sensors. A PCB with a custom motor controller will fit inside the palm of the hand, and interface with the hand microcontroller.
