What I’ve done for others
Here’s a couple of previous projects that I’ve done. I think they’re pretty neat!
To protect the IP of previous companies I’ve worked for, I choose to only display academic or personal projects. Please see my resume for an idea of what professional projects I’ve done. I’m happy to elaborate, within my rights, on professional projects or any of these projects in person or on a call!
Capstone
My 4th Year Capstone Project, a wearable device designed to help firefighters predict dangerous situations and alert them to evacuate. The components are made of a kevlar composite lined with an aerogel insulation. I designed and fabricated the components and required moulds, and tested the heat transfer through and fireproofing/waterproofing of the components.
Helmet
A for-fun project and a gift for a friend, a cat-eared helmet modelled after a character from a TV show. An opportunity for me to use surface-base modelling, and to learn how to infer and measure extant surfaces and implement them into CAD. The ‘ears’ are FDM Nylon epoxied onto a helmet base and the assembly hand-stenciled and painted.
Hull
A 2 meter long carbon fibre hull laid for the UW Autonomous Sailboat Team. Designed to be lightweight, stiff, and buoyant, while still having enough payload capacity to carry equipment, sensors, control surfaces, and a 5m mast and sail. The hull was laid from only 3 layers of carbon fibre, and the deck was laid from a carbon-foam-carbon panel with critical features routed on a 3-Axis router. Machined carbon bulkheads provided lateral stability and structural rigidity. Various mounting pylons and waterproof bulkheads were integrated with adhesives or robust gasketing.
Keel
A 1.5 meter long keel made for the UW Autonomous Sailboat Team. A set of unique requirements made the design challenging. For maximum righting moment, the keel had to be as long and rigid as possible, to put the keel bulb far away from the hull. However, to reduce skin drag, the fin had to be as thin and narrow as possible. This was accomplished with a fin composed of a Textreme skin laid over a steel core, attached to a bespoke shaped lead bulb at its tip.
Rover
A small autonomous mobile robot designed for a search and rescue challenge. The robot was meant to traverse difficult terrain, identify plastic and metal objects, and put out a candle fire. I designed the chassis and all mechanical components, including actuator and sensor mounts. The robot was designed to be amphibious, and could traverse sand, gravel, pits, and smooth surfaces. The chassis was made of laser cut delrin, driven by twin electric motors and a belt drive. Sensor mounts were integrated into the chassis. The robot snuffed fires through a combination of a bespoke nozzle and fin grid over a fan assembly.
Watch
A watch case I designed around a movement CAD I found online. This was a for-fun project to challenge myself to learn Fusion360.
Rudder
The rudder subassembly designed for the UW Autonomous Sailboat Team. Two waterproof servos drive twin balsa core carbon fibre rudders. I designed the profiles of the rudders as well as the requisite tooling to manufacture them, and all of the deck-mounted periphery and linkages. The servo was mounted in a 3D printed waterproof bulkhead on the deck, and connected through a waterjet cut linkage to the rudder. The rudder rod and tube were made of hollow carbon fibre rounds. The ellipsoidal span shape and tapered upper edge reduced induced drag; in testing, as much as 50% reductions were found.
Chopsticks
A carbon-reinforced FDM Nylon case made when my chopsticks case broke. Lunch is very important to me.
