Overview

In this last lab, you will design and build a final project of your choice. Several suggested projects are outlined, but you may also dream up your own project. Suggestions are included for building projects using LabVIEW and electronic circuits learned.

2. Your Final Project

A less than 1 page proposal for your final project with a simple block diagram is due on or before Monday, March 19th This proposal is the only instance in this course where there should be only one sheet per lab team. But you still need to write the report separately. This time frame is for you to be able to order and purchase any needed additional parts for your final project.

3. General Comments

This lab is very different from the other labs. There may be many approaches to your goal. It is up to you to decide which approach is best. Build your project with your lab partner, and take any data together, but your report must be written by you alone. You may discuss the design of your experiment with any of your classmates; however, you are not allowed to copy another group’s work.

4. Project Suggestions

1. For the digitally minded: Measure the acceleration of gravity with LabView as an interface Panel.

2. For the analog minded: Build a circuit which transmits an audio signal over a light beam and then controlled by LabView display Panel.

3. Look on the Internet for ideas about your final project, but DO NOT copy the circuits. Get ideas from them, not complete diagrams. Very little of the circuits on the Internet work properly if at all and you’ll waste your time trouble shooting these circuits. However, you will need some time to trouble shoot your circuits and program.

4. You should use LabView, ADC, DAC, and electronics you have learned in the BSC Lab.

5. Others Projects

Notable projects from previous years include:

1. A circuit that automatically dials a preset phone number (Possibly 767-8900 for the time.) First you would have to use a spectrum analyzer to determine how the dial digits are encoded into the sounds that are sent over the telephone when you dial.

2. An ultrasound motion detector.

3. Acoustic detectors used to determine the speed of sound.

4. A simple calculator.

5. A levitator that suspends a steel ball in air. The levitator works by attracting the ball with an electromagnet, while sensing the ball’s position with a photodetector. The current through the electromagnet is regulated by feedback so that the ball neither falls nor touches the electromagnet.

6. An Acoustic frequency detector.

7. Pong on an oscilloscope.

6. More Suggestions

LabView programs to take data or generate signals etc, should not be ONLY a LabView program, ie; a game or quiz or dice machine. You should have hardware as well as software components in your final project.

Below is a list of suggested circuit ideas. These are only suggestions and you are free to design and build anything with some exceptions. No voltages above those available on your breadboard, although higher current power supplies are negotiable. There are a lot of resources on the internet, just put some keywords into google (or your favorite) and see what is out there. See the TAs for more specific resources. When deciding on a project, try to avoid expensive or rare components. Mechanical components are the leading source of project failure and should only be used sparingly. If you build the same project as another group, you will be forced to face them in a BSC version of robot wars.

7. Student Evaluation of Lab Write-Up

Now that you have completed this lab, we would appreciate your comments. Please take a few moments to answer the questions below, and feel free to add any other comments. Since you have just finished the lab it is your critique that will be the most helpful. Your thoughts and suggestions will help to change the lab and improve the experiments.
