beat-matching indicator

 The clicks made by your indicator match time with the music

Ever get annoyed that the "click, click, click" of your car's indicator when you're at an intersection waiting to turn is out of time with the music you're listening to on the radio? Worry no longer! The beat-matching indicator contains hardware which analyses the music being played over the radio to match the rhythm of the music to the clicking noise of your indicator.

Just use the output from one channel of this. [half, Oct 21 2004]

       A lot of people already do (close to) this when they customize their cars. There are packages you can put in to a car to make the lights strobe with your music. I assume the same thing could be utilized with blinkers, since all they really are is lights with specialized timers.

       I'm guessing Jason didn't want to change the external appearance (it may not even be legal to have blinkers which don't blink in an ordinary fashion).

       Exactly. The indicator, or "blinker", must continue to pulse in a regular fashion, in order not to confuse fellow road users and to avoid breaking laws. Furthermore, don't forget that the pulsing light is accompanied by a "click, click" sound. The idea is to match the sound to the beat of the music, not the flashing of the light.

       Could work well for windshield wipers, too.

       I hadn't thought of that, but you're right of course. Might present a few more technical issues (perhaps you would have to change your musical listening habits depending on how heavy the rain is).

       That's what garage music is for!!!

       Who says you can't (temporarily) reverse the wiper mid-swipe in tune to the music?   

       Note that you could also have the music on a delay loop, so that the wiper mechanism can detect the beat sufficiently in advance to get things moving.

       Should be a pretty easy adaptation of a "color organ" if anyone really cared to bake this.
