Elastomeric foams with embedded photonic senors for 3D touch recognition This work was completed as a final project for Bart Selman's CS 6700: Advanced Artificial Intelligence graduate course at Cornell. For this project, I designed and fabricated a soft touch sensor using an elastomeric foam with embedded infrared (IR) LEDs and receivers. The soft [...]

Soft actuators for kinesthetic interactions in virtual reality Traditional game controllers rely on vibrotactile feedback as the only haptic sensation transmitted to the user. With the advent of consumer virtual reality platforms, users now have the ability to more deeply immerse themselves into videogames with visuals that match every head movement. The ability [...]

Overview We have developed a hyperelastic light emitting capacitor (HLEC) that can expand its surface area by >635% while actively emitting light and sensing this deformation. The center layer is a thin sheet of silicone with embedded ZnS phosphors that glow under a high electric field. Transparent, ionically conductive hydrogel electrodes sandwich the center dielectric [...]

Overview Stereolithography is a 3D printing process that uses high intensity light to selectively cure a liquid precursor into a solid polymer. Historically, stereolithography has used a moving laser beam to cure a single spot (or voxel) of material at a time. Digital Mask Projection Stereolithography (DMP-SL) replaces the laser with a conventional digital [...]

I built this 2D plotter as an exploration of the  CoreXY Cartesian motion system. The frame is made from four 3' sections of aluminum extrusion, the sliders are inexpensive LMU88 linear bearings, and red plastic parts are all printed on a custom built A-101 based on the OS design by Lulzbot. Control is run through [...]

In the spring of 2012, I began my foray into desktop 3D printing. Using money saved up from an internship at Holocene Technologies, I purchased one of the original UP! 3D printers during a clearance sale as new models were being released. This machine proved invaluable to prototyping my senior design project that semester. I was [...]

Disc Launcher This disc launcher was an experiment with designing mechanical parts for low-cost 3D printing using fused deposition modeling (FDM). The toy is completely designed from 3D printed parts that snap together with no need for other hardware. Source files are linked below and as well as a demonstration video. I encourage anyone with [...]

During my senior year at North Carolina State University, I designed and built a CNC router. I performed this work for undergraduate research credit and the project was funded using a Park Enrichment Grant. The machine is designed to cut light materials such as wood and plastic, with a 2' by 4' work area. Fabricated using a plywood structure and off-the-shelf [...]

This project was completed during a two-semester sequence within the Engineering Entrepreneurs Program at North Carolina State University. During these courses, an interdisciplinary team is tasked with identifying and solving a real-world problem. The first semester is used largely for ideation and market analysis. During the final semester each team builds [...]

Skycam was one of the first home projects I designed after buying a 3D printer. This skycam for my apartment was modeled after the cable-driven camera systems commonly used in sports stadiums. The system uses four stepper motors, Easy Driver - Stepper Motor Drivers, and an Arduino Uno to extend and retract four spools of string. A [...]
