Night Stand Bottle Light

Picture of Night Stand Bottle Light
This Project is based off of Scooter76's Cool LED Night Light.

Besides drilling the bottle which quite a while since I was trying to be careful not to shatter it, the circuit part of this project only took about 20 minutes. When you are drilling a glass bottle make sure that you use a special glass drill bit and that you go slow and don't apply much pressure. Take a break every 30 seconds or so and brush the glass dust away, I used an air can made for computer dust. Always wear proper protection such as Safety glasses and proper face mask to make sure that you don't inhale the fine particles.

Step 1: Tools Needed

Picture of Tools Needed
Bottle
Soldering Iron
Solder
Power adapter
Glass Drill Bit
LEDs
Resistors
Wire
Shrink Wrap
Pliers
Wire Stripper

Step 2: Drill A Hole

Here you drill a hole in the back of your bottle and then feed the power adapter wire through the hole and out of the bottle so you can work on it.

Step 3: Switch and Resistors

Here you are going to solder 2 wires to the switch, one on each lead. Then on one of the leads, attach the 2 100ohm resistors. For 2 LEDs, you need roughly 180ohms of resistance. I used 200 because I had a couple 100ohm resistors laying around. You can always use more resistance but never use less, otherwise you will end up blowing your LED bulbs. I finished it off with adding some shrink wrap to cover the connections and to protect it.

you can fill the bottle with mineral oil and it wont affect the LED. Put glitter in the oil or something.

Put water in the bottle while drilling it. This prevents overheating.
