Exercise bike + Yun + temboo + MySQL + html5 Canvas?

Hi everyone!

I'm looking for a little advice on an approach to a possibly slightly ambitious project.

What i'd like to do is connect a hall sensor to my exercise bike, detect and count rotations of the wheel with the arduino Yun, use temboo to upload this to a mysql database on my website, and then create an html5 canvas script to display virtual progress along a path on a custom map, visible online anywhere. I'm not dead sure if the route i'm proposing might be the path of least resistance, has anyone done anything like this before?

I have a reasonable amount of arduino experience and have been messing around with Pi + ifttt recently, but i've not attempted to get an arduino talking to a webpage before. I'm also happy making graphics.

Any thoughts?
