This is a kinetic sculpture of a phoenix, my schools mascot. It is designed as an abstraction of the motion of a birds wings during flight, and creates this motion with two mirrored cam shafts, each with 12 cams offset at 30 degrees. These work in union with a chain transmission and wing profiles to translate the rotation of a single 12V DC motor into a sinusoidal wave pattern. This sculpture is the product of a project in Mechanical Prototyping, a class I took in the spring of my first-year at Olin.
The entire sculpture was first designed in Solidworks, and Solidworks Motion was used to test different sizes and angles in order to find the design that would produce the most pleasing motion.
Dorm Room Loft
My college dorm room has a 20ft vaulted ceiling, which my roommate and I took advantage of with the construction of our loft. We removed nearly all of the furniture provided by the college, put in hardwood floors, and installed pallet racks to act as a foundation upon which to build.
The space which once would have to fit two beds, two desks, two sets of drawers, and two armoires was completely opened up as usable space, which is not only more comfortable to live in, but great for hosting friends and events.
Additions to the space include:
- Standing desk which slides down to serve as a bench
- Transforming beds which are lifted out of the way with whinches
- Kitchenette with fridge, microwave, dishwasher, and food storage
- Custom lighting
- Studio quality sound system
- HD projector with 12' screen
- Window sun seating
- Desks and clothes storage on second level
As the final project for POE (Principals of Engineering) my team designed and built a cable actuated camera system, capable of flying a camera in a classroom to auditorium sized space. It gives similar abilities as a flying camera platform, but with a precision, strength, and silence not found in multicopter platorms.
As one of two team members focused on the mechanical system, I worked on designing and fabricating the spooling mechanism. This project is ongoing, and we are planning on refining the mechanical systems and doing a complete overhaul of the control software to produce a more polished and useful tool.
More information can be found on the projects website here.
A single spool consists of over 20 unique components, most of which we fabricated ourselves.
Reverse Screw Cable Spooling
The self reversing lead screw was custom designed and machined in house. It translates the rotation of the hub into linear motion and a fixed ratio of 1mm per revolution, ensuring precise spooling.
Together with a friend, I built a hexacopter designed to be a sophisticated and powerful camera platform. Our intention was to create a versatile tool we could use to capture and document our adventures and surroundings. We started with the goal of being able to carry a high quality camera and gimbal (GH4 and DJI Ronin or something of comparable weight), and spec'd out the components with those design requirements. The final product is fully operation and it's features include:
- 18lb payload capacity
- 20+ minute flight times
- Fully autonomous flight
- Detailed telemetry and live flight data on laptop
- Video transmission to ground station
- Retractable landing gear, and folding arms for portability
My final project for FOMSO (Fundamentals of Machine Shop Operations) was the fabrication of a Tesla Turbine. Every piece except the bearings and screws was hand machined to a high tolerance, the final turbine spins at over 24,000 rpm without inducing vibration or inflicting damage to itself.
Parts are mostly aluminum, with blades, spacers and shaft made from stainless steel. They were produced using manual lathes, manual/CNC milling, and a water jet for the blade and spacer roughs.
For various classes I have completed a number of sensing labs which integrate a number of disciplines to accomplish a task these projects include:
Line Following Robot - Built on top of provided chassis, capable of installation and removal in seconds - Adjustable sensor mount, allows tuning of sensor location relative to ground and wheels - Leverage PID control to traverse a track as quickly as possible
3D Scanner - Mechanical pan tilt mechanism limits load on servos - Uses IR distance sensor to collect distance measurements in a grid pattern, compiles them into 3D plot of an object
SODAR - Continuously sweeps a room collecting distance measurements - Operates like RADAR device but with ultrasonic pulses - Circuit to filter and and amplify signal using band pass filters - Full lab report can be found here
The inspiration for the project came from an Instructables project which can be found here. Since the software side was beyond the scope of the class we used the code from the project, which creates this user interface showing a map of the area surrounding the device.
User Oriented Collaborative Design is a fully immersive project experience, in which teams work with a people group through the design process to and produce an idea for something to provide value in the space. The process involves user visits, design representations, co-design, and a number of design reviews, and teaches students to keep focused on what is really important when making anything, the experience and value for the user. My team worked with coaches of athletes with disabilities, and I found the entire process to be both challenging and fundamentally impactful on the way I approach the design process.
Business Card Holder
Making things is one of the most satisfying and enjoying aspects of my life, and machining has been a way for me to do this in a more advanced and technical way. This is a simple project I did as a gift for my father, using a CNC mill and scrap aluminium.
I am an active member of the BAJA SAE competition team. I've had my hands in various design aspects including inboard braking, but my main role on the team is as a fabricator. I machined many components for the 2015 car pictured racing, as well as welding some of the suspension members. This year I have taken over the role of primary welder, and am currently completing the 2016 frame. This years car is a work in progress, it should be completed in time for competition in April.
