I participated in the NASA Space Apps Hackathon again in 2018. It is a weekend long competition. My team planned to build a server in Node.js and an Android app that would communicate with the server. The app, titled Launch Now, would show upcoming launches, who is doing the launch, what is being launched, etc.

I participated in the NASA Space Apps Hackathon which is a weekend long competition. I created an application called Shadowfax that allows the user to see a 3D visualization of satellites orbiting Earth, with the ability to zoom into a third person view. There is a server and client component to the application. The server makes a request to publically available TLE data from NORAD. When the client requests data from the server for specific satellites, the server converts the TLE data into cartesian coordinates for every 5 minutes for the specified duration (default 24 hours). The user can view the satellites motion in real time, accelerate time or reverse time. The swath of the satellites largest sensor is visible as a circle on the surface of the earth below the satellites. The application was well received by the panel of judges and won first place in Ottawa. For more details view on GitHub or view the project page
The Falcon Autonomous Quadrotor System was a large project that was done over the course of just under 4 months. The project was to design and build a quadrotor that could stabilize itself independently. The only input required is take-off, land, increase altitude and decrease altitude. All the stabilization is monitored and compensated for onboard. The payload carried by the Falcon is a GoPro Hero 3. In the future of this project, we hope to have the Falcon follow a subject with the camera. This would be ideal for video capture of sports.
In this project, I was the lead software & electrical engineer. This involved a lot of the hardware and software integration, wiring, construction and algorithm implementation.
The Falcon is equipped with an Arduino Uno (because it has highly responsive GPIO ports) and a Raspberry Pi (because it has a more processing power than the Uno and it has USB). The USB on the Raspberry Pi is used to communicate with the Arduino as well as a Wi-Fi card. The Wi-Fi allows it to be controlled from an application running on any device on the wireless network that it is paired with. There is an ultrasonic sensor located on the bottom of the Falcon so that it can monitor its altitude.
Another part of the project that I did was the video. The video is about the development process of the system.
I also did the logo for the project.
I created this title sequence to be used in other videos that I create. It was made in After Effects.
I made this video of the cottage using Adobe Premiere and Adobe After Effects. The video was produced by Mathew Tasson and I.
Beaver Fest/ Beaver Fever is a kayaking video about Beaver Fest where I was a part of the production. I created all of the titles and did all of the effects for the video using After Effects.
