Picture of LED Aqua Bead Nightlight
This is a quick tutorial on how to make a beginner LED Nightlight.  I originally made this for my little brother to help keep the monsters at bay.

Step 1: Materials

Picture of Materials
Large Tube
Small Tube
LED Lights
Wire (anything conductive)
Pipe Cap (fits over large tube)
Lilypad Arduino
Aqua Beads (glass shards, water, etc)
Leather Band
Glue Gun
Small Pliers

You are free to substitute any materials, these are just ones that I currently had.

Iridescent shreds from the wedding section at Dollar Tree would work good in this, even though they would not have the water look, they make a nice "diffused" glow.

It's a controller and you don't really need one

Nope, but if you did want to make the lights fade nicely, it would come in handy. Gives you flexibility. But yeah, a simple battery would be fine.

It's a great idea period, so cool man

Do you think that algae will form in the water in the future? Did you add anything to the water to prevent that?

I was worried about that. Honestly I've had nothing but problems with those little beads. Half the time they are on my floor and the rest of the time they are forcing the center tube to raise to the top. So I'm going to replace them for crystal neck-less beads or some broken glass bottles, that way I can still create the water look without actual water. I will also place something along the inside to seal off whatever I place in the middle. Personally I don't want broken glass all around my house. ^_^

I'm thinking maybe clear glass marbles? Or maybe stuff the perimeter with saran wrap?

A better way to do this would be after the LEDs are connected and ready to go, and tested to make sure they work, apply a small amount of silicone over all of the exposed metal parts. That will make it water proof. So, if the monsters knock it over, it won't be ruined.

Also, for looks, I'd add the same thing to the bottom as is on the top. It will look like an hourglass (SORT OF).

I thought the exact same thing at least with the "adding something to the bottom" bit. The silicone is a great idea though,I wish I would've thought of it at the time. haha ^_^

Cool ible!

What does the Lily Pad Arduino do and is it necessary?

Kamisha King (author)  jimg161 year ago

With the Lily Pad you could program each port to do something different. Not to mention it makes it easy to charge.

I originally planned on programming the lights to fade from one color to another but after days with not a signal light on. I came to the conclusion my Lily Pad was broken and just placed the cords on + and - ^_^

Great idea with the beads! I'd seriously consider SOLDERING those connections however...

Thought: Hack a cheap solar garden lamp & make this solar powered! Simply lean the lamp over so the small PV panel faces the sun during the day, Check ideas at my "Solar Easter Egg" Instructable => www.instructables.com/id/Solar-Easter-Egg/

Niceeeee! Will also look unique on top of an office desk. ;) haha

Love the effect!
