Water Bottle - Track Lighting,




About: Name's Chris. I enjoy taking things apart, modifying and sometimes putting them back together. Like many people here, also have a passion for finding new ways to do things, mostly out of things that others w...

I started working with water bottles a while back and made it into a reflector for led light. https://www.instructables.com/id/Water_Bottle_Hack_LED_Booklight/. It was just a last minute thing, and the beginning of a bigger idea. This instructable is the continuation of what I started, but never had enough inspiration to finish.

Step 1: Materials

For this project you will need:

Lots of LED's - I used, 30 RED, 20 BLUE, 20 GREEN. But you can use any color you like.
resistors 270 ohm
wood - piece i used is 2" x 1" x 62"
water bottles - I used 10 smart water bottles
pref board, wire, wood stain, RGB led driver (optional)

Step 2: Assembly Electronics

Mark out your pref board to the size that fits the bottle neck and cut it out. I used a set of dikes to cut out the circle. Pick out the LED's you intend to use. Lay them out on your board and solder them in. I used this website for my particular needs: http://led.linear1.org/led.wiz It will give you the schematic and the arrangements after you fill in the details of your LEDs.

Step 3: Woodwork

In this step you are going to have to drill holes big enough to fit the bottle cap tightly. I am not sure what size drill to use, since i shaved off both sides of a paddle bit to get the desired size.
All 10 lights are 9 inches apart and all holes were drilled 5/8" deep.
On the other side you want to bore out canal for wires and electronics.
Sand it, stain it, make it look good.

Step 4: Bottle Field

This is where I cut all the bottles. My previous box idea for cutting the bottles just wasn't cutting it. So I had to set up a different rig. Making my rig is a whole different instructable in itself. I am not going to go step by step. Bottom line is to get the bottles cut to size (2.5" from the top). Lightly sand it down.

Step 5: Final Assembly

This is where everything is coming together. Wait for the wood to dry than insert all bottle caps into the holes. You don't have to glue them in if it's a tight fit. Use a pushpin to poke holes and insert your assembled LED in to the caps. For my light I stripped some cat-5 and soldered them on to the leads on the back end. Connect your LED's to desired RGB led driver, or just a 12v power supply and light up your night.

To cover exposed wired you can use a thin piece of wood, or just duck tape over it. Screw in your bottle tops to complete the project.

The RGB driver for my LED's that i am using right now can be found here: https://www.instructables.com/id/Versatile-RGB-LED-PWM-Driver/

    Great project idea. water bottles have so many uses!

    Very nice project! Have you considered spraying the inside of the water bottle with a chrome paint for reflective properties?

    Yes i have, but at the angle the bottle is made, it does not help much. Definitely will not get a spot light out of it. I was getting better results spraying it white.

    Wow! I love these ridiculously specific tools...the last one I saw was the one for screwing Ikea table legs on. Actually, are there any other uses to which you've put this?

    Are you referring to the tool, bottles or the lights???


    Reply 8 years ago on Step 4

    I guess you can use it for anything that could be screwed on (Light bulb), or mixed together (your favorite alcoholic beverage). Imagination a plus. LOL

    Or you can measure the size of the bottle cap and find the appropriate drill bit.

    I didn't think while drilling out my holes to measure my bit, sorry

    I like the different kinds of led lighting that you used. Very versatile to fit your mood. Excellent job!
