Introduction: Bicycle Awareness Siren
The Bicycle Awareness Siren is the first step to avoiding these accidents. This devices features 2 loud sirens and a strobe light that is used to get a driver's attention.
For a little under 50 bucks you can have the safest bike in downtown!
Step 1: Supplies
For this device you will need the following:
1 6 Tone Siren
1 Painfully Loud Mini Siren
1 Mini Strobe (Green)
1 12 v AA battery holder
2 Rope Hooks
3 Bolts with lock nuts
Plastic Container to hold everything
Plastic Container to hold siren trigger
Step 2: Mount the Strobe
First on the front of your holding container mount the strobe light. I drilled 3 holes and pushed in on, using the included nuts to screw it down.
Step 3: Mount Both Sirens
Next mount both sirens to the sides of the box. One siren needed a bolt, the other had some sticky velcro. Be sure to drill holes to thread the wires through.
Step 4: Mount the Rope Hooks
Measure your bike and position the rope hooks so they drape over the handle bars. I used 2 screws to mount them on there.
Step 5: Mounting the Switches
I put the larger switch on the main box to control the strobe. The smaller switch went inside the smaller container to control the siren.
Step 6: Wire It Up
I wired the strobe to the battery and then wired both sirens to the battery through the switch. I used a long piece of wire to go from the sirens to the smaller switch so i can mount the switch wherever i need it.
Step 7: Add Velcro
Use a Dremel to make two slots and fit velcro into both containers. Then run the velcro through each to attach it to the bicycle.
