Reader Leo was doing some recycling recently and came up with an alternate use for one of those musical birthday cards. All text and the picture credited to Leo.

I was putting out the recycling and came across the birthday my folks sent me and realized, I can’t put the noisemaker in the recycling bag, so I tore the card apart to pull out the sound.
I got to thinking, “This might work as a bell when coming up behind people in a bike lane” so I started fiddling with it to see where it would fit on my handlebars, close to the brake levers and noticed, duh, the speaker is a very strong magnet, so voila!
It rests on my frame and a cable tie secures the switch to the frame, so all I have to do is touch that and the fanfare to Star Wars blares! This is a foundation hack, for all of you mechanical sorts, there should be lots of ways to improve on the idea.
