Picture of Make Your Own Vintage Bike Buzzer
It's prime bike trail weather right now! Have you ever been on a busy bike trail where a simple "On your left" or "Coming through" is not quite enough to alert headphone wearing, walkers, talkers, and "jazzercisers" of your presence?
Well a couple of weeks ago I was remembering bikes that had shiny, cool looking (and loud) electric buzzers on their handlebars. Next thing you know I noticed one at a swap sale (pictured above)...but they wanted $30 just for the buzzer!...the seller claimed that he's seen just the button go for $15....too rich for me, so I passed on the sale.  When I got back to "the internets" I found that I may have missed out on a bargain...many similar vintage buzzers are being sold on ebay for upwards of $40!

This Instructable resulted because I decided now was a perfect time to try to "make one myself!"  (and hopefully wake up some walkers!)

Materials Needed to Make a Bike Buzzer:
- 1 12V DC buzzer $.75 cents from my favorite surplus store (they have buckets of these things)
- 1 momentary pushbutton $1.50 - easy to find
- 20" twisted pair wire - had some spare trailer wire laying around, worked perfectly for this (especially for Packer Fans :-()
- 9V battery (I tested the buzzer and it worked great at 9V)
- 9V battery holder
- Electrical Tape

Materials needed to make it a Vintage Bike Buzzer: 
- 1 Chrome Ray-O-Vac flashlight - $2 - Found at a swap sale, the perfect look... some of these are still available new. Nicely fit the buzzer exactly!
- 1 top of a 2 liter pop/soda bottle
- 3 zip ties.  
- 1 Universal Velcro flashlight handlebar holder - $4 (or more zip ties) - already had one of these

Tools needed:
x-acto knife
drill (for hole in the flashlight and bottle top)
soldering iron (optional)
