Hobbies

I am an avid disc golfer, photographer and videographer, FPV pilot, and gamer. I spend most weekends working on technical projects, playing video games, kayaking, and riding roller coasters in the Orlando area.

Interests

I am a thinker and ideas guy. I am interested in things like philosophy, cosmology, nature, and just the way things are and why in general.

Projects

Pulsar

Pulsar is an animated LED dragon I made over the course of 3-4 months to take to an electronic music festival called EDC. It consists of foam paper, cut and folded into a dragon, the model for which I found online. The LED's inside the head and back have a few pre compiled animations that are selected over bluetooth UART with a mobile phone (iOS in this case). I decided to make the dragon out of foam instead of 3D printing out of plastic or flexible material because I wanted it to be robust towards getting danced with and bumped into for several days. Pulsar was a hit at the festival and I've since moved him to my office to sit next to my desk, where he slowly fades through rainbow colors all day.

Code can be found here, and the video goes into detail on the rest.

RFID Door Lock

The easiest way to leave my apartment was through a glass sliding door onto the back porch. The only problem was that it couldn't be locked from the outside, so I decided to design an embedded device to securely lock the door from the outside behind the glass. The entire circuit and device was designed and made by me. The housing was 3D printed and the circuit lies on a perfboard embedded in it. A servo moves the locking lever when an authenticated signal is detected by the RFID reader behind the glass.

Code and circuit diagram can be found here, and the video goes into detail on the rest.

Light Circuit

I wanted something to really add some personality to my apartment so I came up with the idea of creating a poster that symbolized my passion for the marriage between art and technology. I came up with the idea for a circuit that you could watch flow and would look cool at the same time. I learned A TON about electronics, soldering, optimizing code, and quality construction. 360 solder joints and around 60 feet of wire later, it was finished.

If you would like the Arduino code, you can find it here. You will have to download the fast spi library first.

SkyLog

This was my capstone design project in a Human Computer Interaction class. Our goal was to improve the workflow of a professional, highly skilled job. My partner and I chose pilots and this is the result, an app for pilots to log their flight hours for the FAA. The app was designed by the both of us and coded by me while my partner wrote the paper.

This android app was written in java utilizing an SQLite database for storing the data. It was designed to be as user friendly and intuitive as possible while still providing all the functionality the pilots we interviewed required. The app took about 3 weeks to code and we recieved an A on the project.

Pictured are my low fidelity prototypes on notecards. High fidelity prototypes were done in powerpoint.

Acrylic Comics

I wanted to make something special to personalize the walls of my apartment. I have always been into the classic superheroes and watched many of the cartoons and movies as a kid. I decided to mix that passion with the minimalistic art style to create something that really represents my interests.

The result was what you see here, my five favorite comic book heroes and villains, designed in adobe illustrator, glued together, and mounted by me. Laser cutting of the acrylic was done by a company called Ponoko. I think it turned out pretty well.

This Website

My website has gone through quite a few iterations as I have learned more about web technologies, design, and optimization. The current version is the culmination of a lengthy design process for me to really update the aesthetics and increase my artistic ability to be on par with my technical skills.

This site was designed and built from the ground up by me, using the foundation framework. All of the interaction and aperture code (mouse hovering over the menu items) was written by me. The apertures were inspired by a combination of my fascination with how they look and work, and my interest in photography.

I graduated from the Colorado State University Computer Science department with a BS in Applied Computing Technology (ACT).

ACT is a submajor of Computer Science. Same basic programming classes as any other CS major, but instead of upper level math and science classes oriented toward research, I took business classes like management, marketing, finance, and so on that was designed to prepare me for broader roles in software companies and startups.

• Object Oriented Design
• Java
• C and C++
• HTML, CSS, AJAX, and Javascript
