Lunch-n-Learn: Finding Rockets in the High Desert with HTML5

Hey folks, sorry for the last-minute notice.  I woke up with the urge to shake things up a bit for today and thought I might as well present something I've been having fun with lately ...

What's the talk about?  Well, the Oregon Rocketry club has a problem: when you launch a rocket 1000's of feet up you don't always know where it comes down.  Finding them can be really hard, and losing them can be really expensive ($100's of dollars in time and money).  I thought it'd be fun to take a stab at trying to find some of these lost rockets by writing a little web app that uses HTML5 to do real-time video processing to help searchers locate spectral anomalies (i.e. rockets!) out in the scrub brush.  I'll demo what I've done so far, and then we can drop into Q & A from there.

What will you learn?  You'll learn how to use the new HTML5 video API to access a webcam, process the video in realtime, and display a modified version of that video, also in realtime.  You'll also learn a bit about the local rocket scene.

Whos the talk for?  Pretty much anyone with a curious mind.  Some grasp of programming will be helpful since I'll be walking thru a small amount of code, but it's not required.  I'll keep the geek-speak to a minimum.

Cheers, and please RSVP by 11am so I have a sense of how much pizza to order!  (BTW, donations go to the Tech Alliance and help pay for pizza)

      Was there to be an upload with this? If so, where do I find?

    Robert, sorry I missed this. I am a model rocket fan and interested in what you have been working on. I am hoping to teach basic rocket building and thrust/altitude understanding & calculations at Bend Creative Lab.

      Hi miles, no worries - this was more a mental exercise than an real project. But it's a fun demo of emerging web technologies (I think) - I'd be happy to give you a quick demo the next time we meet. Also, I have a web-based rocket simulation app I've been working on that you might be interested in.

    This sounds really interesting. I hope my RSVP at 11:01 am was not too late. I like pizza.

    Nice.
    I work for Geosoft. We identify anomalies to help find unexploded ordnance. Curious about your app, but can't make it. Will you send out presentation after event?

    I already have lunch plans and we're demoing a space portal. Sorry!

    Wow! Now that's creative use of a lunch hour, Robert... Good Stuff (-\
