Our project is a slide guitar-like instrument with a single string. A microcontroller reads MIDI input and controls two motors to play the instrument. One motor moves a metal bar along the string to control the pitch and the second motor controls a wheel of guitar picks to strike the string. A guitar pickup convert the string vibrations to an analog signal, to which the microcontroller reads and applies audio effects. The resulting digital audio is converted back to an analog signal and sent to speakers.

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.

Hardware

• 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
