Hi, I'm an engineering student at Howard Community College, Howard County Maryland.

This is my engineering projects portfolio. These are the classes I have had projects in.

Disassembling Brother MFC-5890CN Printer

Introduction
I am an engineering student at Howard Community College. My professor is Muhammad Ali Yousuf. I am planning to transfer to UMD: College Park and study software engineering there. This is a page where you will find the links to all my projects and my group project pages.

Disassembling a printer
For this project. We disassembled a printer and we identified all the parts in a printer. We saved all the useful parts that we thought were going to be needed in the future projects. We also documented the whole project in our engineering notebook. We also researched about all the parts that we found.

Computer Aided Design
Today in class I started learning CAD. It is very useful software in engineering to design 3D and 2D designs which give us a very good idea about how the product will exactly look like.

Group 1 Robot Project
Our groups goal is to make a robot that can do multiple things at a time. Specifically our group is trying to make a robot that will detect the darkest spot in a room, go there and be able to light up a bulb. Another task we are trying to make our robot do is to make it detect an object in front of it and make it go in another direction so it doesn't crash into the object. So overall, our robot will avoid the obstacles and go to the darkest spot in the room and then light up a bulb.

We made a rough sketch of how our robot is going to look and we researched about all the parts that are going to be needed to build a robot. We made powerpoint presentation too which briefly explains our whole project.

My task for this project was programming. I had to program the robot so it performed the specific task. I helped out with different things somewhat but my main task was programming. Me and Jonathan worked together to figure out the programming part of the project. I also found 2 videos on how to program a robot which I am going to use to learn how to program. And the link to the two videos is http://www.duino-robotics.com/programming-your-robots.html

Guitar Pickup Group
Guitar Pickup Group

This project is very interesting to me because I got to learn many new things about the guitar which I never knew. I had no background or information or how things work in the guitar. But through this project I learned many useful things. I learned about the guitar pick up itself and how it works. I also researched some stuff about it and learned many other things through a website. website: http://www.lollarguitars.com/mm5/merchant.mvc?Screen=technical-info

Also I got to learn about the OpenSCAD software. We got to learn many new things about the software through Mr. Ali's OpenSCAD presentation. We used OpenSCAD to design a 3D sketch of our final design of our guitar pickup.

For This project, our group decided to build a guitar pickup for an acoustic guitar. Acoustic guitars don't have a built in pick ups so we are trying to build a pick up that will pick up the vibrations from the guitar strings and sen it to the speaker/ amplifier to the wire. That's our goal for this project but we will probably finish it before the deadline. Since we probably will have time left, we will try to work on the sound modification part of the guitar which will be able to adjust sounds, volumes, tones etc.

My contribution to this project was to research about the different ways to coil the copper wire around the magnets so it could improve the quality of the sound it produces through the string vibration it catches.

We started building a prototype of our final project. We basically took the magnets out of a hard drive of a computer and put it together using the hot glue. Then we wrapped the magnets in a copper coil wire. We then attached the two ends of the copper coil wire to the aux cord and that was basically our prototype of our final design.
