Have a look at my new spoke length calculator web app!

Thanks for all your hard work on this, looks like it's going well.

Why not put a Paypal link for donations? (I'd happily donate if it helped successfully undertake a daunting build, etc.)

I'll take payment in form of blog and forum posts and general spreading-the-word. Maybe you could make a screencast on how easy it is to use. Once I have enough visitors I may choose to monetise (ads, link to a bike shop where you can order spokes) - but for the time being this is just my hobby and showcase of what I can do (I leave uni in ten months).
