Background
The motivation behind this project is that often when riding around campus or in a large city where we are not too familiar with specific locations, it can be hard to having Google Maps (or similar) open while riding and results in us stopping frequently. Our project aims to counter this issue.

Our idea is to have create a smart bike that helps you navigate to your destination. For this, we would have LEDs on the bike handles that light up based on what direction you need to turn in. The rider would have an application open on their phone that integrates Google Maps and sends directions to a microcontroller on the bike via bluetooth. In addition to this basic feature, we have a few other features and potential additional features (time permitting) that we plan to implement as part of our project. to make sure we are riding in the correct direction.

Basic Features
-> LED lights on the bike handle that blink in the direction that you need to turn
-> Increased frequency of the blinking light as you get closer to the turn
-> Turn indicators/blinkers that light up automatically when you turn
-> A speedometer on the bike

Additional Features (time permitting)
->Alerts when you get close to another vehicle
->Headlight that turns on automatically when it gets dark and adjusts the brightness according to the surrounding brightness
->Vibration on the bike handle before turns during the day because the LEDs might not get your attention

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.
