How I made this awesome glass filled led light bulb.


Step 1: Materials

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

-Blue led (other colors would work)
-Light bulb (best if its burned out)
-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)
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
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.
this has got me thinking, add some mix of coloring oil and water, and/or colored glass/leds
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.
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! -.-
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?
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
jeez, someone thought of the RGB led idea...damn
i think i am going to make a basic stamp version of this with a bicolor led and a reg led!
Cool! Post pictures when you do
ill see what i can do
For 120V power, you could use a few <a rel="nofollow" href="http://www.allelectronics.com/cgi-bin/item/NE-210/search/NEON_LAMP_ASSEMBLY,_WITH_RESISTOR_.html">neon indicators</a> hooked up in parallel. It'd be red-orange, not blue, but it would eliminate circuitry.<br/>
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.... <br/><br/>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 <br/><br/>Blue Neon bulbs <a rel="nofollow" href="http://www.goldmine-elec-products.com/prodinfo.asp?number=G15710">http://www.goldmine-elec-products.com/prodinfo.asp?number=G15710</a><br/><br/>Green Neon bulbs <br/><a rel="nofollow" href="http://www.goldmine-elec-products.com/prodinfo.asp?number=G16489">http://www.goldmine-elec-products.com/prodinfo.asp?number=G16489</a><br/><br/>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 ))) <br/>
yay i have some 60V ones laying around
Or a capacitor and a bridge rectifier( or 4 diodes)
My point was that you wouldn't <em>need</em> the rectifier or capacitor...Remember the KISS principle?<br/>
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.
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.<br/><br/>It is a very cute solution. Essentially, the capacitor in series with the AC power limits the amount of <em>current</em> 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:<br/><br/><a rel="nofollow" href="http://www.discovercircuits.com/DJ-Circuits/whitelednight.htm">WHITE LED NIGHT LIGHT</a><br/><a rel="nofollow" href="http://www.discovercircuits.com/H-Corner/mod-led-nite.htm">Modified LED Night Light</a><br/>
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
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!
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....
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.....
Thats why it stays next to my computer on my desk. These break very easily
very cool!
i got cut 16 times and im blaming it on u!!!!! jk...lol
did you make one? pics?
You can power LED's directly from line voltage. Find the schematic here (with many more):<br/><br/><a rel="nofollow" href="http://www.discovercircuits.com/">http://www.discovercircuits.com/</a><br/>www.discovercircuits.com/PDF-FILES/acwhiteleds.pdf<br/><br/>Or here:<br/>www.instructables.com/files/orig/FCM/R9MK/FDLVVGZP/FCMR9MKFDLVVGZP.pdf<br/>
Wow, can't believe I didn't see this one before. Very nIce and (<sub>as far as I know</sub> )original!<br/><br/>PLus 1.<br/>
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!!!!
Its easier to just get real lava lamp. Maybe I'll try the gel thing.
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?
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 :(
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.
Cool! Post some pictures if you make anything
