Walking in the rain can be a drag even with an umbrella. But this may make things a little more bearable.
The BBC has a report on a new umbrella that's loaded with sensors. Each raindrop triggers a random 8-bit tune.
Creating such a thing turned out to be more tricky than first expected. How sensitive should the sensors be? How to tune the controllers to generate a pleasing sort of tune? How to attach the sensors to the umbrella and power them?
They managed to work it all out--mostly. But even then co-inventor Alice Zappe says "It does get a bit annoying after somet ime."
