2016/2017 Projects

 

FLIR Security Camera

 

The main objective of this project is to design a small solar powered security camera that is reliable, cheap to install, and inexpensive at volume. The security camera module will be based around a thermal camera, thanks to FLIR.

 

This is a UCSB College of Engineering multidisciplinary project encompassing the Computer Engineering, Electrical Engineering and Mechanical Engineering capstone classes and is sponsored by FLIR.

Gestur

 

With the releases of the Oculus Rift, HTC Vive, and Microsoft Hololens, virtual environments are reaching a new level of fidelity. Unfortunately, these devices lack the feedback to create truly immersive environments; while our eyes and ears might be fooled, our hands are not. There are some companies building haptic feedback exoskeletons, though their solutions are bulky and overly complicated. We believe that we can make a significantly simpler device that can not only accurately monitor your hand movements, but emulate sensations of touch through the use of piezoelectric polymers, IMUs, and small 3-d printed parts.

Hyperloop 2

 

The UCSB Hyperloop CE team seeks to support the development and testing of the Hyperloop pod for entry into the SpaceX competition. This will be accomplished through implementation of a comprehensive system for sensing and controlling critical aspects of the vehicle’s operation, as well as transmission of necessary telemetry data for control and review.

 

This is a UCSB College of Engineering multidisciplinary project encompassing the Computer Engineering, Electrical Engineering and Mechanical Engineering capstone classes.

IR Hub

 

The purpose of this device is to solve the problem of having to clutter your living room with one or more infrared remotes through the use of a Bluetooth controlled, IR Hub. The Hub will be capable of learning and repeating signals transmitted by IR remotes, allowing users to control any IR enabled device from an app on their phone from anywhere within Bluetooth range of the Hub.

OstraCam 2

 

This project's intended purpose is to gather information of bioluminescent planktons, ostracods, which will be used to study the species. We will create a mobile underwater system that will record low light images, salinity, pH, temperature, pressure, location and time. Continuing off of the progress that was made last year, our goal is to change the microcontroller and add additional pieces to expand the device’s capabilities.

 

This is a collaboration between the Computer Engineering capstone class and Professor Todd Oakley, UCSB Department of Ecology, Evolution and Marine Biology (the project sponsor).

SONOS Intercom

 

A hardware module that contains a microcontroller, WiFi module, and microphones with basic DSP for voice input.  The system should use API to connect to Sonos players.  The students should optimize the design to achieve clarity on different types of voices, in different type of environments and optimizing the processor loading.  The final product should be attractive and compact, and pass Sonos’ design criteria. 

 

This is a UCSB College of Engineering multidisciplinary project encompassing the Computer Engineering, Electrical Engineering and Mechanical Engineering capstone classes and is sponsored by SONOS.

Course Spotlight

 

ECE 189A & B is a year-long senior capstone project in which students, working in small groups of three to five, design and implement an embedded computer system incorporating both significant hardware and software components and, in many cases, mechanical components as well.

 

During the first half of this course sequence, student groups choose a project, define and refine a description of its external behavior, then launch into the hardware design phase. By the end of fall quarter, using industry standard Computer Aided Design tools, they have produced detailed hardware schematics, fabrication-ready printed circuit board artwork, and complete component kits and associated documentation necessary for prototype assembly.  An organized project notebook describing all aspects of the project as well as formal design reviews/presentations and the use of professional project management software complete the initial portion of the capstone design experience. 

 

During winter quarter, the ECE department has the printed circuit boards fabricated and assembled and, when students return for the second half of the capstone project course, the focus turns toward overall project integration.  On the first day of spring quarter, circuit boards are ready for initial power up, design debug and verification. In parallel, creation of the project software begins and any mechanical components are acquired and/or manufactured and assembled.  Once the hardware design is validated and the software and mechanical development efforts are completed, the final project prototype is integrated, tested and verified.  A succession of milestones, reviews and presentations ensures that project completion and introduction occur in a timely and successful manner.

 

At the end of spring quarter, each project team participates in the Computer Engineering portion of the Senior Capstone Project Presentation Day.  During the day long event, the groups display posters highlighting their projects’ features and operation in the department’s courtyard and conduct a public presentation and demonstration of the completed projects.
