Step 1: Materials

What you need:
Tools
-Pliers, leatherman, or similar
-Soldering Iron
-Screwdriver, hammer, etc (for breaking glass)
-Clips or clamps


Parts
-Blue led (other colors would work)
-Light bulb (best if its burned out)
-solder
-Wire
-Broken glass (clear)
-Scrap of plastic
-Power source (batteries, usb cable, wall wart)
-Shower thingie (what goes between the head and the wall to cover the hole)
-glue (testors model glue, or just use epoxy)
-epoxy
-Tape

Step 2: Prepare Light Bulb

Now that we have all of our materials, we start by taking off the bottom of the bulb and breaking out the filament and other inner parts.
Using pliers pull off piece of metal on the bottom.
Using a screwdriver break out the dark glass on the bottom.
Break out the glass holding the filament

Step 4: Fill with glass part 2

Fill the bulb up the rest of the way with more glass.
Take a piece of plastic and cut it into a circle the size of the hole on the bottom of the bulb.
Poke 2 holes in the plastic for the wires from the led to go through.
Pass the wires through the holes and put in on the end of the bulb and glue or epoxy it.

This is awesome! And so pretty! I want one! But alas I do not have soldering skills or a solder or LEDS. :0( Awesome instructable though!

if i have to plug it in a socket what should i do
LastDevil5 years ago
Very Well done there mate ;) I'd want to try something like that but not sure if it would work and i'm not crazy enough to do it :)

you should try to use colored mineral oil.
jtet375 years ago
this has got me thinking, add some mix of coloring oil and water, and/or colored glass/leds
revhead5 years ago
this is a nice Instructable. very easy to follow and interesting. I might make one of these that is powered by a joule thief so that I can have a cool night light for my coffee table, and put those half dead AA batteries to use. thanks for the idea.
LinuxH4x0r (author)  revhead5 years ago
Thanks! Be sure to post some pictures of the finished product.
AAGGHHH!!!! I WAS PLUGGING IT IN AND MY ELBOW HIT IT!!!! Noooooo! It took me three Afternoons to make!! And now I'm out of lightbulbs! -.-
LinuxH4x0r (author)  Zippy_Pyromaniac5 years ago
GRRRRR! I hate when that happens D: My concrete lightbulb broke!!!
Can I cover up a small hole the size of a pencil in the bulb with some scotch tape?
LinuxH4x0r (author)  Zippy_Pyromaniac5 years ago
I suppose so

Or you could buy a bag of clear plastic chunks from the craft store. They also sell small polished pieces of glass and light colored agates. Either would work and should be a lot safer than broken glass shards. This statement of course for those of us who consider ourselves to be foul fumblers of fragmented fragile things...

I made one a while ago and used 2 LEDs. Still have to make a base though. One note on breaking glass: watch out for glass powder. It's dangerous if you inhale it and it's a real PITA to clean up
darkmuskrat6 years ago
jeez, someone thought of the RGB led idea...damn
conrad24686 years ago
i think i am going to make a basic stamp version of this with a bicolor led and a reg led!
LinuxH4x0r (author)  conrad24686 years ago
Cool! Post pictures when you do
ill see what i can do

For 120V power, you could use a few neon indicators hooked up in parallel. It'd be red-orange, not blue, but it would eliminate circuitry.
These are a fairly unknown neon bulbs ok they don't use neon but they are the same voltage rating ( 120 Vac ) and size, as the Ne-2H Orange / red bulbs most people know , they are kinda rare. But they are BLUE and GREEN, and not like most cheap indicators which use a orange neon and green / blue plastic filter, which still look orange they are true blue and green bulbs....

Now I got my when Radio Shack was closing out in Canada a few years back,(( 90% off )) and I don't remember the part numbers and they might still carry them in the US but the Source by CC in Canada doesn't ... I did find them at electronics goldmine and they do mail orders

Blue Neon bulbs http://www.goldmine-elec-products.com/prodinfo.asp?number=G15710

Green Neon bulbs
http://www.goldmine-elec-products.com/prodinfo.asp?number=G16489

And in the kiss principal is neon bulb with the already attached resistor of the right value, empty light, solder and 120 VAC and you should get about 5 to 20 years of service out of it .... ((( the neon bulb on my freezer still works and it's from 80's )))

yay i have some 60V ones laying around
LinuxH4x0r (author)  CameronSS6 years ago
Or a capacitor and a bridge rectifier( or 4 diodes)
My point was that you wouldn't need the rectifier or capacitor...Remember the KISS principle?
Also, I don't see how that circuit works--Isn't it running an LED off of 120VDC? It seems that you'd need about a 5K ohm resistor in there, without a transformer on the AC side.
Derin CameronSS6 years ago
well that is too low of a resistor value my calculations show that with 50 leds a 7500 ohm is needed
Nope, you don't need a bulky transformer or a huge current limiting resistor in this circuit.

It is a very cute solution. Essentially, the capacitor in series with the AC power limits the amount of current that can flow through the LED. The circuit LinuxH4x0r linked to is the minimal version. Adding a capacitor across the LED would be a good next step. Here are two other, gradually more complicated versions from the same website:

WHITE LED NIGHT LIGHT
Modified LED Night Light
Why can't the LED just do the rectifying? It will only be on 1/2 the time, but isn't the frequency high enough? I'm just trying to figure out why the LED doesn't break...

Do it with a 3W LED star :D
ScienceWiz6 years ago
Couldn't you just fill it with glass and pop a throwie into it then seal it back up and save a lot of time, idk. I'm gonna make one, great idea and cool pictures!
LinuxH4x0r (author)  ScienceWiz6 years ago
Thanks! The reason I don't is because I don't want to have a battery I have to change. Thanks, and post pictures if you do
...i would look for something other than glass....i wouldn't want to bleed to death before seeing how cool it looked....
LinuxH4x0r (author)  explosivemaker6 years ago
Never cut myself making it. Thanks though
well thats good to hear.... ...it be a big bummer if it broke.......o what a mess that would be.....
LinuxH4x0r (author)  explosivemaker6 years ago
Thats why it stays next to my computer on my desk. These break very easily
giannyl6 years ago
very cool!
LinuxH4x0r (author)  giannyl6 years ago
Thanks!

i got cut 16 times and im blaming it on u!!!!! jk...lol
LinuxH4x0r (author)  rakol16 years ago
did you make one? pics?
You can power LED's directly from line voltage. Find the schematic here (with many more):

Wow, can't believe I didn't see this one before. Very nIce and (as far as I know )original!

PLus 1.
LinuxH4x0r (author)  Keith-Kid6 years ago
Thanks! I got the idea of using glass from the blue bawls bottle one, and I've been obsessed with lightbulbs ever since I made a concrete lightbulb
I once had an idea, to make a lava lamp or something similar to this. Get a container, fill it with gel. I dunno some sort of gel. Then put in an LED, then fill with gel again. The point is, I was looking for a way to make the gel spin, so it looked coo. I gave up cuz I dunno were or how to find gel
Then I just gave up, put the LED, filled it with hot glue and put the bottle over an electric motor. It spinned anyway!!!!
LinuxH4x0r (author)  Keith-Kid6 years ago
Its easier to just get real lava lamp. Maybe I'll try the gel thing.
technomorph6 years ago
No step down resistor for the LED so it doesn't get burnt out as quickly with the direct 5V your feeding it via USB?
LinuxH4x0r (author)  technomorph6 years ago
I'm pretty sure the usb cable has one built in (It hasn't burnt out yet, even though I've burnt the same ones by connecting it directly to the port)
COOOOOOOOL! But I havn't got any LEDs :(
LinuxH4x0r (author)  Baron A6 years ago
Thanks I'd send you some if you didn't live so far away (England, right?)
Yeah, most instructablers live in the U.S and a small minority live other wheres like England. But, its cool I'm getting some from a "local" hobbyshop.
LinuxH4x0r (author)  Baron A6 years ago
Cool! Post some pictures if you make anything
I will, Hopefully i might have a sudden brain-child (idea), and get the urge to make it with LEDS.
linuxmom6 years ago
Your best yet.......keep it up. Hope you win!
MerlUno6 years ago
You can use a while lightbulb you just pour salt in there and shake it, and dump it out.
im making this but i'll have to find a clear bulb
LinuxH4x0r (author)  Yerboogieman6 years ago
You can do it with a white bulb, but you just need to wash it out (theres powder in there to make it white) Post pictures
MerlUno6 years ago
Looks like you got some preddy big shards in there. I think i've seen this done before.
LinuxH4x0r (author)  MerlUno6 years ago
Yeah, thats why it looks so dim at the top (besides the photography). Could you provide a link?
Josho6 years ago
+1. I have made something similar to this.
LinuxH4x0r (author)  Josho6 years ago
Thanks! Do you have any pictures?
Hey, nice job LinuxH4x0r!
This is like this Instructable, reminded me a lot about it.
Awesome job, you're probably going to win something awesome hopefully!
LinuxH4x0r (author)  GorillazMiko6 years ago
Thanks! Actually I got the idea from the blue bawls one. I hope I win. under 5 mins and I got 10 views and 3 comments
thats the one i was thinking of
I hope you win something too! I got a new one (Instructable) too! It's on my page, but it hasn't showed up yet.
LinuxH4x0r (author)  GorillazMiko6 years ago
Hope to see it soon!
Go to my page, it's there. :-) Check it out if you want! And +1 rating to this Instructable.
LinuxH4x0r (author)  GorillazMiko6 years ago
Thanks for the + Made with knex and it doesn't suck! Witchcraft! Its actually a pretty good idea
Thanks! I was inspired by a few other Instructables too.
Goodhart6 years ago
Very interesting....
Patrik6 years ago
Looks lovely! I'm looking forward to the 120VAC version, preferably with a high-brightness LED... :-)
LinuxH4x0r (author)  Patrik6 years ago
It's bright, I justt made the mistake of putting all the big pieces of glass on th top. I hope to make the 120vac version totally enclosed so I can just screw it into a normal lamp. Thanks for all the help.
Sunbanks6 years ago
I like this! It looks really cool. I think I might try making one. Oh how I wish comments had an edit button....
Patrik Sunbanks6 years ago
It's called "delete and repost". If nobody has answered yet, it'll be complete unnoticeable.
LinuxH4x0r (author)  Sunbanks6 years ago
Thanks! Please post pictures If you decide to make one. Actually its good they don't have edit. It could cause lots of confusion
Ok Good point.
Brennn106 years ago
This looks pretty neat! Nice job!
LinuxH4x0r (author)  Brennn106 years ago
Thanks! I'm planning on making one that you can actually plug in to a 120 volt lamp using the schematic provided in the last step.
