Intro: Water Bottle - Track Lighting,
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.
