The project is a data tracking device for Howard Schein to use to easily acquire accurate lap times and set rest periods during swim training. The device will eliminate the need for coaches to manually obtain lap times for swimmers. It will track swimming lap data within a waterproof box set next to the pool where swimmers will trigger a sensor each time their given lap is done. The device will consist of a three-piece wireless unit; one piece is to acquire and transmit data (lap times, rest times, etcâ?¦), another piece is to analyze and store data (lap length, lap times, rest times, etcâ?¦), and a final piece to adjust data variables (lap length, rest times, etcâ?¦). The device will provide swim coaches with accurate lap information transmitted wirelessly to their computers allowing the coach to track and adjust data.

Prosthetic Control Board

Featured Project

Psyonic is a local start-up that has been working on a prosthetic arm with an impressive set of features as well as being affordable. The current iteration of the main hand board is functional, but has limitations in computational power as well as scalability. In lieu of this, Psyonic wishes to switch to a production-ready chip that is an improvement on the current micro controller by utilizing a more modern architecture. During this change a few new features would be added that would improve safety, allow for easier debugging, and fix some issues present in the current implementation. The board is also slated to communicate with several other boards found in the hand. Additionally we are looking at the possibility of improving the longevity of the product with methods such as conformal coating and potting.

Core Functionality:

Replace microcontroller, change connectors, and code software to send control signals to the motor drivers

Tier 1 functions:

Add additional communication interfaces (I2C), and add temperature sensor.

Tier 2 functions:

Setup framework for communication between other boards, and improve board longevity.

Overview of proposed changes by affected area:

Microcontroller/Architecture Change:

Teensy -> Production-ready chip (most likely ARM based, i.e. STM32 family of processors)

Board:

support new microcontroller, adding additional communication interfaces (I2C), change to more robust connector. (will need to design pcb for both main control as well as finger sensors)

Sensor:

Addition of a temperature sensor to provide temperature feedback to the microcontroller.

Software:

change from Arduino IDE to new toolchain. (ARM has various base libraries such as mbed and can be configured for use with eclipse to act as IDE) Lay out framework to allow communication from other boards found in other parts of the arm.
