Greetings Plymouth High School

Greetings Plymouth High School

The following is my electronic portfolio, some examples of engineering class work I have done.

Four Corners Challenge Project
The Four Corners Challenge Project is to operate efficiently, machines need their parts to fit precisely and to work together smoothly. The challenge is to build a machine out of cardboard that runs smoothly and dependably.
An example video is is listed below:

Picture of Four Corners Challenge Project

Investigate tension and compression
In this project we built a paper bridge and chair prototypes out of paper. What shape makes the best bridge? Learn about how shape plays a role in designing sturdy structures.
An example video is is listed below:

Blimp Jet Project
The Challenge si to add a jet-propulsion system so that a blimp flies straight and far under its own power.
An example video is is listed below:

Feel the Heat Project
In this project we designed and built a solar hot water heater and see how big a temperature change you can get.
An example video is is listed below

Below is examples of our Manufacturing Engineering Program

9th Grade Capstone Project
Line Following Robot Project - Design of a ultra fast line following robot project for student engineering technology project. Worked in conjunction with Electronics Engineering, Drafting and Precision Machine Technology provided a “canned” project. Robot would follow a black line (electrical tape) on the floor autonomously, via infrared led and infrared photo transistor. The engineering student program an algorithm in the Arduino. Students assemble the electronics and build a custom machined chassis and wheels. Students would “tune” the program to different track conditions.

10th Grade Capstone Project“Blimpy” Blue-tooth Controlled Blimp Project - Design of a ultra light modular control system for student engineering technology project. Worked in conjunction with Electronics Engineering, Drafting and Precision Machine Technology provided a “canned” project. Students assemble electronics and program the project, both in the Arduino IDE and a custom application on the cell phone using MIT APP inventor, scratch programming. Student would also design custom 3-d printed chassis in Solid Works

(Exploratory Project) – A universal remote control allows you to turn virtually any TV On or OFF. We prefer OFF. You control when you see TV, rather than what you see. The TV-B-Gone remote is so small that it easily fits in your pocket so that you have it handy whenever you need it, wherever you go: airports, restaurants, laundromats, etc. TV-B-Gone is a type of Universal Remote Control which works by shining pulses of invisible light that tells most any TV to turn OFF or On.

Exploratory Curriculumhttp://www.n1ir.com/p/exp2016.html
During our 5 day exploratory students build and take home ten unique projects. In an effort to reduce cost to the district I designed my own projects and documentation at a tenth of the cost of purchasing an off the shelf kit from a electronics supplier, Cost of my kits runs about $1.50 each.
