This instructable will show you how to make an electronic glow stick. If you are smart, you will probably figure out how to do it by the first step. keep in mind you can make it more elaborate if you want (switches, battery cases, solder, more LED's, etc.)


This instructable is now featured in Popular Science magazine! February 2010, page 79. Look for "originally posted by Shane Dulong on instructables.com"

Step 1: Supplies

Needed:
- Battery (3 volts or bigger, within reason)
- 1 LED of your choice (4 shown)
- 1 Bic pen with translucent (partially see-through) case

you really need to put a resistor in series with the LEDs to limit current. Otherwise you will be constantly replacing LEDs
wat are the steps?how to connect the batteries i need explaination guys
The short wire goes on the negative part and the long wire goes on the positive part. Either hold it there or tape it. If using the button cell it will usually stay on its own.
umm... your green led is yellow, that means you have too much power in it.
I know. I pointed that out when I said us a 3v button cell instead. I didn'.'t have one.
oh ok then :)
