Welcome to my site
Nicholas J. LaMacchia
I’m thrilled to invite you to explore my work, skills and experience, and get to know a bit more about me. It is my goal to begin my career as part of a multi-disciplinary team responsible for designing and developing innovative products that will improve lives and advance technology. I am energetic; eager to learn; possess excellent time management skills; and work well independently and collaboratively. It’s my firm belief that a good challenge is a great way to develop and improve, which is why I make a point of seeking out challenges in the professional realm as well as in my personal life. Take a moment to look around, and contact me directly to learn more.
I have been a life-long resident of Billerica, Massachusetts and was lucky to have the opportunity to attend Shawsheen Valley Regional Technical High School. It was at Shawsheen where I developed a love of learning and passion for engineering. I excelled in the electrical field, which provided me with a diversified skill-set. I enrolled in Merrimack College's Mechanical Engineering program where I had the opportunity to collaborate on some exciting solo and collaborative projects. I take pride in all that I do and in the long-term relationships I've fostered in the process. Experience has taught me that hard work eventually pays off. I know that each day brings me closer to reaching my goals. Explore my portfolio and feel free to get in touch with me with any questions.
What I’ve Done
Day in and day out, I’m constantly taking on new and interesting projects that help me build my personal brand. From industry-related tasks to unusual and sporadic opportunities, each experience I’ve had has turned me into who I am today.
The following is an overview of three of the many collaborative and solo projects I completed while attending Merrmack College. Powerpoint presentations can be viewed by clicking on the links below.
3D Printed Prosthetic Skiing Leg
September 2016 - May 2017
This 3D printed prosthetic skiing leg was a year-long, collaborative project completed during my senior year at Merrimack College. This project won first place for Outstanding Senior Design Project.
Design a product with a team utilizing all the skills acquired during our undergraduate engineering education
Execute engineering ethics while producing a product that falls within reasonable constraints
Display evidence of consideration of design aspects including effectiveness, material selection, safety, cost, environmental effects, ethics, production, etc.
Suitable for a beginner skier with a height of 5'10" and weight of approximately 200 pounds
Lightweight yet as strong as possible
Athletic prosthesis for above the knee applications can cost over $70,000. By creating a new design of a prosthesis that would be 3D printed, we are able to substantially reduce this cost. For the prototype we researched how total knee replacements function, as this would best replicate the movement of a knee for our design.
Skee Ball Machine
The Skee Ball Machine was a collaborative project. We needed to design and construct a fully functional skee-ball machine that possessed all of the qualities of the popular arcade game. Some of the main focus points of the machine included the ball return system as well as the scoreboard that keeps track of the points scored by each player.
The electrical circuit was applied to the underside of the pocket board
A phototransistor was applied to the back of each pocket; each with a jumper cable attached connecting them to the beadboard
The phototransistors detect when a ball is scored into the pocket and sends a signal to the scoreboard to record a score
A scoreboard with a LED light display is connected to the pocket board to show the score each time a ball is deposited into a pocket
Each pocket has a different point value
The correct number of points are added to the score
Improvements for Future Design
Improve code and develop way for phototransistors to detect the ball when a specific player tosses the ball
We were able to construct a low cost, functional, stable, and marketable skee-ball machine using wood, PVC, and other household materials resulting in an old-fashioned game feel.
Mini Piezoelectric Sonar
For this project we wanted to create sonar with the use of three different piezoelectric crystals of different geometriics (circle, cube, and rectangular plate). We needed to find a way to waterproof and insulate the piezooelectric buzzers. To proceed with our experiment, we sent an electrical pulse at different frequencies through a piezo buzzer underwater, and were able to read the signal through another crystal underwater with an oscilloscope. We tested each crystal and collected data from running tests at multiple distances. Finally, we analyzed and plotted our data and presented our findings to classmates.
Research the development of piezoelectric crystals and how they were implemented in sonar
Fabricate miniature piezoelectric sonar and record data using an oscilloscope and frequency generator
Organize data using Microsoft Excel
