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

Filtered Back – Projection Optical Demonstration

Featured Project

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.


• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
