Step 1: What You Need
2. Plastic water bottles (0.5L) - thinner plastic = better for this project
3. Spray paint/acryllic paint
4. Painter's tape
5. Red LEDs - 20mA at 3V
6. Battery holder + 3 AA batteries
8. Solder and soldering Iron,
9. Wire cutter
10. Super Glue
11. Some pointy tool to punch holes.
Step 2: Make Ready
Place the crushed bottles on to the aqua blue core like you want. I did a 10 rows by 4 columns arrangement to give it a modern look. Measure the length and breadth and divide into 40 squares. Find the center of each square and using a pointy tool, punch a hole at the center.
Clean the base with a dry cloth to get rid of any dust. Spray paint it the way you like it. I gave it a red border with an aqua blue core. Leave it to dry. Go crazy here!!! Paint it how you like it. You don't even have to paint it. You can cover it with different kinds of paper/fabric/newspaper ads that fill up our mailboxes... anything.. or just leave it like that.
Step 3: Sticky Sticky
Super glue the caps onto the board with their inside facing away from the board so you can screw the bottle on later. Let it dry.
Step 4: The LEDs Finally
Cut about 6" long strips of electrical wire (I used green for -ve and blue for the +ve terminals). And solder a green to the short leg of the LED and the blue to the open end of the resistor. Insulate the two connections from each other using electrical tape. I made sure I twisted them far apart so they would never come in contact... but insulating is always the better thing to do.
When you have all the LEDs soldered, check the connections again to save you rewiring misery later. Thread the green and the blue wires thru each bottle cap and the cardboard so the LED + resistor sticks out from the cap. Screw the bottles on.
Step 5: Almost There!!!!
You can nail it directly to the wall or build a quick wooden frame for it an dthen hang it.. your call. Ping me if you have questions... And if you like the project, please rate it generously. I am entering it for the Let It Glow contest. Thanks!!
