This is a water bottle hacked to make a nice little LED light for the laptop, desk or wherever. It's an ongoing project that I started a while back and today I decided to enter it into the Water Bottle contest. This project is far from fully complete but it will give you a general idea of the possibilities it possesses. Feel free to build upon this idea and recycle!

Step 1: Materials

For this project you will need:

Smart water bottle since it's probably the smoothest bottle out there for our purposes
rubbing alcohol (optional)
Solid copper wire
LEDs-color of your choice
spray paint-colors are your choice
box large enough to hold bottle (optional)
bread board to hold LEDs in place

tools: exacto knife, soldering iron
very creative! I likes :)
&nbsp;Well holy crap, thank you.<br /> <br /> Recently got myself a lot of super bright wide angle LEDs to slowly work on a small solar power system and was trying to figure out how to use them in an easy and yet half way attractive way. I thought the idea was cool but thought &quot;But I know when I cut the bottles it would look terrible&quot;, and then see you give a super easy way on cutting them down.<br /> <br /> You are my hero.<br />
I'm glad you like it, since then I did automate the bottle cuttine technique,&nbsp; http://www.instructables.com/id/Water-Bottle-Light/step4/bottle-field/<br /> <br /> Thanks <br />
I would love to wire about 50 of these up around my boat slip, but I haven't a clue how to run them off 110v A/C. Can any one help with a power supply? I could build it or hack it. Just not sure how to design it! LOL
There is a way to do this.<br/>You can string them like Christmas lights, all LED's connected in series. Refer to this instructable, <a href="http://www.instructables.com/id/THE-LED-LIGHTBULB/">http://www.instructables.com/id/THE-LED-LIGHTBULB/</a> Adding 3 more LED's to his 46 will now change the brightness that much. From there you should be able to to split 49 LED's in to groups of 7 per light. At this point you going to end up with 7 lights. Parallel that seven more times, and you going to end with close to what you want.<br/><br/>Or you can drop the voltage down to 12, throw in resistors and parallel everything. <br/>Let me know how it works out. <br/>
Holy Cow! This is clever!
Thank you, glad you like it.
Good Stuff
This is way cool. I want to do it, but need more instruction re: basic LED's. REALLY great pics give me a good idea, but never having done it, I didn't even know what a breadboard was until I saw the pic. Could you do an 'ible on just the 7 LED light config you have there? Or point me to one? Really basic - the LED link above is way beyond my current kinder-knowledge on this. Got my vote.
I will post all that info in part 2 of this instructible, It will be as soon as i get all my parts in the mail. There is a instructible on LEDs for Beginners, <a href="http://www.instructables.com/id/LEDs-for-Beginners/">http://www.instructables.com/id/LEDs-for-Beginners/</a> very helpful, and it has few good links in there for arranging led. . Here are some pictures of arrangements that ware used in my instructible, There is 3 led in parallel, on each side, and one single LED in the middle. supply voltage is common. <br/>
Very cool! You could probably get even more reflection if you painted the outside with a chrome spray paint, then covered it with what ever color you wanted the outside to be. Don't color the inside; that way the bottle acts as a clear coat over the coat of chrome pain. I don't know if this will work but it is worth a shot! If i get a chance to try it i will let you know how it goes.
I wasn't really going for the reflection. Originally intended as track lighting, with soft light. It was never intended to be a spot light. I did paint the inside, because i was short on time, and i didn't feel like waiting for the paint to dry. I hope you have a chance, and take some pictures, really interested to see what it would look like. I will continue with part 2 of this Instructable when i have more time. Thank
I decided to try it your way, and painted chrome, it actually came out good. I didn't even have to use a second color, since i liked the all chrome look. Thanks
Genius bottle cutting device!!!
Nice looking project Here's an old RC car trick(but in reverse).... Paint only the outside! Start with a white primer, then apply the color. You'll still get the white inside color, but with , imho, much easier application. I really dislike trying to spray evenly into stuff, without dripping. If the shiny interior bothers you, before painting, give the inside a quick scrub with fine grit sandpaper. The frosted appearance will eliminate the "glare".
Genius! I've been yearning for a way to make custom reflectors...
Sup bro pretty cool!!! I was bored and found you. Say hi to mom for me...
Thanks Bro, don't forget to vote.
