Our project consists of creating a decoration similar in concept to a typical lava lamp, but using ferrofluid and magnetism instead of wax and heat. We would also like to allow the user a good degree of interactivity with the display.

The design is as follows:
A ferrofluid will first be mixed into a liquid of similar density. This will then be placed into a glass cylinder, at the top and bottom of which will be electromagnets. This will be used to control the upwards and downwards flow of the ferrofluid.
Our design will also have electromagnets that can be made to move vertically up and down the "lamp." We propose three separate magnets situated around the central cylinder in equal increments, each in its own separate, and smaller cylinder.
These can be made to pulsate, which we expect can be used to either split the liquid apart should it turn into a single ball (turning all 3 on simultaneously and briefly) or induce circular motion of the ferrofluid.

The plan is to allow the user to specify the speed at which the main electromagnets (ones on top and bottom) move the liquid up and down, as well as the movement and on/off operation of the three vertical magnets (interestingly, the user could have the 3 magnets do completely different things... the result of which we are yet unable to visualize).

To achieve the vertical movement of the three outer magnets, motors will be incorporated into our design.

As an aside, we realize that the three outer magnets can be used to achieve upwards and downwards movement. In this way, our design is somewhat redundant. However, we also want to allow the user the option to simply have the fluid drift upwards and downwards, without any horizontal interference.

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
