Bicycle Car Horn (Revision 2.0)

I've revised my bike car horn. I placed it in a better location, upped the loundnes to around 140db, cleaned up the presentation a bit , and increased the size of the battery pack. More details are in my project's LJ: jvs_projects. If you want to hear it, I made a little video. You can find it on my myspace video's page We ride tomorrow and test it. :DEDIT: I rode 20 miles today and not a single car/person/animal tried to collide with me. I even rode around downtown in the middle of the day for nearly an hour. jv
