axe.light #hardware #packaging #software #gamedesignbeep n seekAn interactive and modular game concept for kids. Designed in March 2013 in EE 27N.***
Components
Arduino Uno, XBee Shield, XBee, LED, speaker, button. Battery powered. Plexiglass tupperware case.
My Role
Hardware lead: hardware choice and assembly, packaging design, Arduino / Zigbee software troubleshooting.
Gameplay
Players hide all nodes and must find them in order, competing to see who can find them the fastest. Active nodes flash a light and emit beeping sounds that increase in frequency with time, until the player presses the button on the node.

#machining #solidworks #designaxe.lightA quirky, portable lamp for the outdoor enthusiast or young at heart. Created in December 2014 in ME 203.
Components
6061 aluminum, acrylic internal encasing, cherry, CREE LED. Battery powered.
My Role
Conceptualization from start to finish: sketching, 3D modeling, prototyping, machining, electronics, woodworking.
Inspiration
The pickaxe holds special importance as a symbol of the relationship between man and the enviornment. I wanted to pay tribute to this while creating a whimsical mood reminiscent of being outside camping.
Concept sketches exploring form and detailed component sketches
Initial prototyping using wood: chisels, belt sand-ers, bandsaw
CAD modeling in Solidworks: part, assembly drawings
Iterativemanufacturing-grade prototyping, component testing
axe.light
Pressfit flexible coil spring pin, allowing angle adjustment of lamp stand
Pressfit acyrlic housing for electronics
Pressfit cherry handle for secure mobility and movement

#solidworks #toydesign #injectionmoldingWally
Concept design for an injection molded wind-up toy in which the user celebrates a birthday with a beached whale. Created in May 2016 in ME 181.
My Role
50/50 with one of my closest friends: brainstorming, whiteboard sketches, mechanism design, 3D modeling.
Explanation
The user winds the party hat atop the head and releases, causing the flippers to flap vertically and tail to shimmy from side to side. Who says beached whales don’t know how to have a good time?
Wind-up motor interfaces with a cental axle via bevel gears
Scotch and yoke mechanism creates tail shimmies. Scotch fixed to central axle via a radius
Elliptical disk collides with flippers each revolution, creating vertical flapping
Wally Squatting Toilet
#solidworks #vacforming #shopbotcnc #sanitationSquatting Toilet
Concept prototype for toilet design to improve health outcomes in urban communities. Research grant in Civil & Environmental Engineering in 2015.
My Role
Core designer working with 3 Ph.D can-didates: whiteboard sketching, 3D mod-eling, manufacturing, enclosure plans, interview material prep, on-site testing, installation, and monitoring.
Explanation
An interactive prototype designed around users through interviews and benchmarking local toilets in Khulna, Bangladesh.
Components
styrene sheets, PVC, MDF, fasteners.
Mold for toilet pan modeled in Solidworks, prototyped in Shopbot CNC, styrene pulls in vacuum former
Plans for enclosure drafted and passed off to local artisans
Interactive tests with users helped determine form of future prototypes
Squatting Toilet
Opening / closing mechanism is a slider that must be lifted up and back, designed from interactive tests with users
#solidworks #lasercutting #motorsRoopert
A motorized pentapedal kangaroo featuring a 4-bar slider-crank linkage system. Created in March 2016 in ME 112.
My Role
Team of 4. Designed and analyzed linkage systems and geometries, designed components in Illustrator.
Explanation
A motor powers the front legs, with a timing belt connecting the hind legs and tail for ordered movement: front, tail, hind. Roopert has a top speed of 2 inches / second.
Components
Tamiya 72005 DC motor, lasercut acrylic, timing belt components, fasteners.
Roopert
All interfaces between different materials fixed using adhesives
Roopert is held together with a ventral platform and metallic crossbar
#gearratios #motors #analysisThe CrawlerA motorized lego crawler. Created in February 2016 in ME 112.
My Role
Team of 4. Analyzed gear ratios, output of power and forces relative to motion threshold, iterating crawler design accordingly.
Explanation
Design a motorized crawler to scale platforms spaced 6” apart and oriented at 60 degrees. Gear ratio 512:1. Third best motor efficiency out of 35 crawlers.Restricted materials.
#solidworks #drawingsMotorboard
Concept design for motorized skate-board. Created in April 2016 in ME 181.
My Role
Whiteboard sketches, all mechani-cal design work, models, and draw-ings.
Explanation
A design for a motor mounted to the board, transmitting power to the rear axle via a timing belt. In-cludes truck, idler gear, brace, and mounting components.
Motorboard
Part and assembly drawings created with appropriate detail, dimensions, and specificity for creating a BOM.
Components designed for manufacturability, empha-sizing casting and machin-ing processes.
