Introduction The project involves an experiment in implementing a human-computer interface by tracking finger and wrist motions. Brief: “Ever wish you could control a computer just by moving your fingers or your hand?” We did. The primary goal is to design and build a functional prototype implementing an intuitive interface for a user to interact …
Introduction Infrared (IR) Our project is an infrared (IR) tracking system. A beacon, placed on the object to be tracked, continuously emits infrared signals in all directions. The signals coming from the beacon are detected by 2 IR receivers mounted on 2 stepper motors, which rotate independently and are in separate locations. The direction each receiver …
Introduction: Our project is a UPC-A Barcode Scanner complete with a pricing/description database interface. Our original goal for this project was to build a standard barcode scanner from scratch, but as the project evolved so had to our specification of the project. We initially sought to build a charge-coupled device (CCD) scanner, which scans the entire …
Introduction We created a wireless device to affix to the bottom of a pitcher that alerts the wait staff when the pitcher is empty. We used the a priori knowledge that when a pitcher is empty the pitchers bottom is perpendicular to the ground. By affixing an accelerometer to the bottom of a pitcher we …
Introduction Objective The goal of this project is to design a useful and fully functional real-world product that efficiently translates the movement of the fingers into the American Sign Language. Background The American Sign Language (ASL) is a visual language based on hand gestures. It has been well-developed by the deaf community over the past …
Introduction The objective of this project was to build a keyboard based on capacitive sensors and then use the MCU to create MIDI encodings for all notes played. The output from the sensors is detected by the MCU using its ADC capability. The sound is played directly by the MCU via a piezo speaker using …

Objective and Background <> Objective: The gift of sight is precious; that is why we tried to model an artificial retina with the properties of color detection, saccades, and pursuit tracking. Structure of a Retina: A retina lies in the back of the eye and consists of a layer of photoreceptor cells called rods and …
The goal of this project was to build a versatile, yet easy to use, sensor-triggered camera controller for high speed photography. Dan Furie (djf35) Scott Linderman (swl28) High Level Design Inspiration Our motivation came from photographs that captured a very small moment in time, such as a water droplet splattering from a faucet or a …

Introduction Our project is a self-contained system that helps people develop the musical skills of perfect pitch and relative pitch. Push buttons allow the user to navigate a graphical user interface (GUI) on a liquid crystal display (LCD). In perfect pitch training mode, a note is played and the user tries to identify the note …
For this week I set out to make a board that will show realtime MBTA bus arrival times using the ESP8266 wifi module and a LCD. Seemed doable. People of the internet have been excited about the ESP8266 lately. Here is a snapshot of google trends for searches for esp8266 vs couple of other arduino …
