Have you ever gotten in an accident while riding a bike at night or close to an accident? Gotten honked at because of irresponsible drivers who aren't paying attention to the road? Or simply just want to make bike riding more safe? Riding visibility on a bike is at all time lows during night time considering of little space we take up and as well as us not being able to have car headlights blinding everything and everyone. If you agree with at least one the above statements, then the Automatic Activated Blink Signal is just for you!! Check out the awesome EL panel, lighting up like lightning! Drivers will be sure to notice you riding, and not crash you! It will ensure 100% safety when you're riding your bike through dark streets at night as well as having hands free operations.
This project will automatically turn on an EL panel with a mercury tilt switch. By extending your arm or raising it slightly, the mercury will complete the circuit, resulting in the EL panel to light up brightly whether solid or blinking. Give this project a try, and you'll be amazed.
Step 1: Materials
First, you'll need to gather the necessary materials for this awe-inspiring project:
1. EL Panel w/ AA-powered AC Inverter  *these may be separate or if you'd like to have solid EL panels, soldering might be required)
2. Mercury Tilt Switch 
3. Velcro strips [4-6 pairs]
4. 1.5V Button Cell--LR44 / AG13 
5. Electrical Tape
6. Armband 
[#] indicates the amount needed
Step 2: Placing the Button Cells
First, grab a piece of electrical tape--just a tiny piece, enough to double side and fit snugly attached to the battery.
Next, use the piece of electrical tape and "loop" it so that both sides are sticky.
Stick it to any side of the button cell and place it in the battery compartment--with the negative side of the button cell touching the spring of the battery compartment.
Repeat these steps for the second battery compartment.
*The negative side is the side without writing!*
