Coca Cola bottle night light.

I decided to make an LED nightlight out of a round coke bottle.   I had this idea before I saw the other instructable by lambsb, but I noticed that he/she used a flashlight bulb instead of an LED, so I figured I'd go ahead with this.

Step 1: What you will need

You will need:

*Round coke bottle
*Switch (I prefer the 1/2 inch push button)
*LED
*Resistor
*Button battery with case (small size)
*Soldering Iron and Solder (mine is taped together for this instructable)

**The cost of the materials was about $3.00 not including the coke bottle.   If you order the materials off of the internet, it will cost a  LOT less money.

Very nice instructable, thank you for it! I saw lambsb's first, but I prefer yours... now I need to find some empty bottle :)

Thanks.  I could have done it better but at the time I didn't own a soldering iron so thats why I used tape. lol. 

By the way, don't use tape to piece together circuits, it's dangerous even if you are only using small batteries.  I only did this for the instructable, but then took it apart until I could get a soldering iron. 

I also forgot to add the resistor, although I'm not sure if you would really need one or not.

I always add resistors where needed... so I will definitely be adding one here lol

That looks really cool! Where did you get the round Coke bottle?

Walmart.  The other user who made a similar lamp had 2008 on his bottle, so I assume they are only sold on holidays.   I didn't realize they had them last year.  Mine is 2009.

 I got one this year at walmart to

 Nice light! Although, technically you don't need the resistor since white LEDs draw an average of about 3 - 3.5v, and the coin battery only supplies 3v.

In this case the resistor is for safety and is only used to regulate power surges, not "pull down" voltage. The author does not state the size of the resistor so I am assuming it is very small.

 Ohh, okay, I see now, thanks.

At first I thought you made the typical cylindar bottle into a spherical bottle. I've never seen one of these spherical bottles sold in Michigan. When were they sold?

I was just thinking at Christmas when I got one of these in my stocking that I'd love to reuse it as an ornament. Yours looks far neater and easier than lambsd for a n00b like me. Say I wanted to merge the two designs and have it able to attach to the socket in a light set on for a tree ornament, any tips? I can't tell exactly what you've got feeding the LED in this.

Im not sure how you would make a plug-in version, but I would think it would be too dangerous to use AC with that type of plastic.  

I used a button-cell battery.   It has to be small enough to fit through the neck of the bottle.   My version was just taped together for the instructable because i didnt own a soldering iron or any other tools when I made it. lol

 That's adorable!  I have a ton of mini bottles.  Might make string lights!
