Description: Our project will implement the swim pacer unit in a variable speed LED strip (50m). It will be placed at the bottom of the pool (weights added to keep it aligned)
Each of the strips will contain a battery, controller with pre-programmed profiles, LED displays. They will be extended to the side of the pool and waterproofed.
LED display shows the speed of the pacer and the laps the swimmer is going to swim.
Each of the LED will be connected in series with a micro-controller to reduce wiring and the size of the strip.
The LED will be different at the end of the strip. It is programmed to be faster to account for when the swimmer pushes off the swimming pool wall. The colors of the LED would also be different
to indicate to the swimmers that the end of the pool is near and gets him ready to turn.

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.
