I created the YouTube channel Engineering Explained. It now has over 100,000 subscribers, and pays my rent. AMA!
I create videos once a week on how cars work, and post them to my YouTube channel www.youtube.com/engineeringexplained. I started the channel with about $50, for a whiteboard and markers. It now has provided me the opportunity to collaborate with companies like Nismo (Nissan Motorsports), where I got to check out the ZEOD RC and Nissan GT-R Nismo GT3, as well as Shell, where I attended the Eco-marathon in Houston, TX. I'm an avid Reddit lurker, but not much of a poster. Ask me anything!

Edit: My desk can use a cleaning. I'll be around for a while to continue answering questions. http://imgur.com/pQxnkDq
Edit 2: Thanks for all the questions!! I've finished cleaning my desk (many hours later... http://imgur.com/kFwtidF - made room for my new computer which arrives tomorrow), and now I must rest. I'll answer any straggler questions from the Aussies tomorrow. This was fun!
