Be sure to update your Table of Contents prior to submission.

Appendix A. Tables and Exercises

The Binary Number System

Within Appendix A. Tables and Exercises and under the subheading The Binary Number System (in Heading 3 style) enter the questions below and supply your answers.

1. In your own words, what is the ASCII Table and explain its purpose. Provide a link to this web site in your ER.
2. In your own words, what is Unicode and explain why it was required. Provide a link to this web site in your ER.
3. What is your surname in binary? Present your answer in a well-formatted table.
4. Translate the encoded message below into English with the help of the ASCII Table. Use a well-organized and formatted table to present your results.

   

   Here is the code in text form if you would find it useful. A word of advice: You could convert the binary codes directly to decimal (Base 10) and then look them up in the ASCII table, but you may find it easier to convert the binary numbers to their hexadecimal (Base 16) equivalent, and use these values to determine the character. Not to mention the benefit of further experience with the important hexadecimal number system.
5. Question 2 on page 66.
6. Question 3 on page 66.
7. Question 4 on page 66.

Do not forget to update your TOC. Submit your ER as an attachment to an email to handin with the Subject: The Binary Number System

Project 1. Modifying the 9V Adapter

You are ALL potential engineers. You must believe in yourself. For this first project, and all others to follow, please keep in mind that the quality of your work is a reflection of the respect you hold for yourself. High quality results are achievable by anyone willing to demonstrate passion and patience in their work.

A Regulated 9V AC DC adapter is better suited to our prototyping activities than 9V batteries. Disposal of the latter is problematic and battery clips snap with frustrating regularity (there's a reason they give you a half-dozen of them).

Task.

1. Alligator clips offer a better interface with the breadboard than the barrel jack. Using the cutting jaw of the Wire Strippers, cut cleanly through the cord, roughly 5 cm from the jack and give the end to Mr. D. These components can be reused in future projects.
2. Following more detailed instructions provided in class, strip the sheathing from the power cord a further 4 cm and remove the sheathing from the red and black supply leads, 2 cm from their ends.
3. Remove the red and black soft plastic covers from the alligator clips and slip them on the red and black leads, respectively.
4. In addition, slip a half-length (1.5 cm) of heat-shrink tubing over each of the read and black leads.
5. For each lead, slide the exposed copper through the hole in the clip and loop it around again to the jaw of the clip making sure it maintains good contact with the metal clip. Using a pair of needle-nose pliers, crimp each wing of the jaw over the wire, one at a time.
6. Slide the heat-shrink tubing over the joint and, using the heat gun, shrink the tube to strengthen to the joint.
7. Slide the soft plastic covers over the clip and test.

Engineering Report

Employing the best practices discussed in MIT's Technical Writing document, follow the instructions below to complete the first entry in your Engineering Report.

1. Organization is a key to success. Create an appropriately-named folder on your laptop (i.e. Circuits, TEL3M, Hardware) to house the files related to this course. Within this folder create a subfolder entitled images that will house all the photos and graphics you will create in this course.
2. Within this folder, create a Word document entitled ER.docx.
3. Follow the instructions provided in class for creating a title page, Table of Contents, and Project 1 page.
4. For Project 1, include the subsections: Title, Reference, Purpose, Procedure and Summary.
5. Complete the text of each section, written in Active voice, embedding right-aligned photos that you took to document the development of the project.
6. Finally, never forget to update your Table of Contents as the final action prior to submission.
7. Attach your Engineering Report to an email to handin with the Subject: Modifying the 9V Adapter by the required due date.

Project 0. Lemon Power

Before you begin your year, you should decide what your approach will be.

Are you a minimalist, whipping the work off as fast as you can to simply 'get it over with' ?
Or, at the other extreme, are you prone to rambling on in the hope that the teacher will eventually find everything anyone could possibly include on a topic?

My recommendation lies in the middle. Think deeply and write economically.
A succinct, well-conceived response will maintain your readers' attention while still garnering the credit you're hoping for.

Section A. To get the juices flowing so to speak, you are asked to explore the ability of a few simple household items, in combination, to generate electricity. Undertake the steps outlined below and records your answers and measurements.

1. Without resorting to any form of research, what is your simplest, straightforward explanation for the concept of electricity?
2. Research the basic construction of a dry cell battery (e.g 1.5V AAA, AA, C, D) and, in your own words, include a simple, straightforward explanation how this kind of battery works.
3. What are the two fundamental units used to quantify electricity in a circuit.

Section B.

4. Turn on the DMM, position the center dial to Volts, V, and toggle the FUNC button so DC appears on the LCD screen.

5. Google an image of the electron shell for Zinc. How many electrons inhabit its outer shell? Do the same for Copper.
6. Why might these observations make these elements well-suited for the promotion of electricity?
7. Explain how inserting a galvanized metal screw and a copper penny in a lemon mimics the construction of a dry cell battery.
8. Using your alligator clips and DDM probe, measure and record the voltage of your lemon battery.

Section D. Presumably the purpose of understanding electricity is so that we can put it to work. Typically this involves assembling a sequence of components that convert electricity into useful output. Each of you have been given the same type of LED.

9. Your LED is a useful device. It converts electricity into visible light. Remembering our discussion of the design of an LED, connect it to your lemon battery and record your observation of its behaviour.
10. Is the output of your LED any different from the other students'?
11. Explain how you could work with a partner to improve the output of the LED.
