Sleep is not restful here. The clouds serve as reading lamps. The sodium vapor glows. Cloudless, moonless nights, I can see my feet. The darkness will not come. Night escapes we tired city dwellers. The sodium glows just as bright as before. The ancients knew what night was, They couldn't see their hands in front of their face. They went to sleep at dusk. We modern night owls fire up the street lights. The ugly sodium glow.

Today I saw heaps of instructables about glow sticks. I searched for a glow stick guide and I found nothing. I can't be bothered enough to make a guide... So I'm just telling anyone who reads this topic; If you want to make a guide, make it about glow sticks.

I dunno if u've seen the glow graffiti but it think its an awesome idea but not worth $50 http://www.thinkgeek.com/gadgets/lights/b5ba/i just wanna take some fabric or canvas and make it glow in the dark... anyone know how i can do this?

How to make glowing tie with LED diods?

After getting hit by a car while riding at night (even though I had lights) I am considering powder-coating the frame of my bike with a glow in the dark additive. I was wondering if anyone had attempted this before, and if you had thoughts on it. Also, can you powder-coat spokes? I know powder-coating the rims is bad because it interferes with the brake pads functioning, but I'd really like my bike to be as visible as possible. 

Does anyone know what happened to the Make it Glow contest (ended 12/31)?  I can't find it anywhere on the site through general navigation (recently closed contests).  It was sponsored by Radio Shack and I now see in the Contest FAQ that "We recently discontinued our sponsor/prize provider program for sponsor contests."  Did the plug get pulled on this contest? Thank you!

So I'm relatively new to nitro rc and i had a few questions about on board glow plug ignition system  . I know the igniter is cheep and bla bla bla easy however... Can one be made ? I have often thought that i might be able to use a third channel off my receiver with a wire directly to the glow plug and at the flip of a switch the glow plug would ignite but i don't know if it would work and don't wanna spend the money on a receiver  to find out. Is there someone out there willing to give it a go and let me know?  Really my question would be at what voltage does a glow plug ignite? would a 7.2 volt battery do the trick? Are there any CHEEP systems out there?

The header says "LEDs, EL Wire and Lightbulbs".  Does your project have to include at least one of those, or can it be anything that glows? Thanks!

If you take a look at old Ibook G4 there is a stand-by LED that kind of glows slowly, I wonder what do i have to do to archive it, it would be perfect if it wound go dark completely yet would simply change brightness between say 70 and 100% so should i change voltage accordingly or? if yes then How? and wouldn't it be bad for the LED itself and for the battery, it is also important to mention that i'm going to use one or two AA batteries as a source. please help.

This is my first actual post though I've loved the site for a long time now. Anyhow I have two new cats, beautiful friendly, I love them to bits. The only trouble is they are very dark furred and there's been a couple of times they've hidden in plain sight. Me and my fiance are both worried about stepping on them I thought some glowing type collar would be cool. I've been searching the web for an answer and I can't really find anything so I decided to make one of my own. I have limited experience with electronics, I saw the post with an ewire I think it was called collar for dogs. I should be able to figure that out however the cat collar would be much smaller and I don't think it would comfortably sport the battery unit. I ditched the idea of glow in the dark paint (flaking and the cats probably wouldn't appreciate the fumes). I considered some glow-in-thedark hot glue.. but I don't know how to do that without making a collar look lik ea stiff, plasticy, mess. Maybe weaving some of the glow in the dark plastic laces into a collar kinda like the paracord bracelets? Anyone have any other ideas? Anyone heard of some glowing material or even glowing material dye? Thanks :)

I am thinking of putting some glow tubing on the inside of my 14 foot jon boat, mainly for night fishing. It would also make it look really cool at night. The concept is simple, some of you may know - clear tubing from the hardware store, filled with water, with an LED in either end. This should light it up even if it is curved, right? I want to put long tubes running the length of the boat, on the inside groove of the side runners. That would mean 13+ feet of slightly curved glow tubing. I may have to end up splitting the glow sticks into smaller sections, but would like to see if I can do long single tubes. I'm concerned that the light will fade out in the middle considerably. I'm OK with it fading a little, but I don't want it to be noticeably bad. Will a narrower light beam help solve the problem? (found some 12 degree online) I will go for the narrowest beam and highest candlepower possible.  Am I on the right track? Got any advice?  Thanks a bunch

I use nitro rcs alot and use quite a bit of glow plugs and at five bucks each . i want to know if these are possible to repair or extend life

The judging for the Let It Glow! contest has been extended to Midnight July 1, which is one day later than originally planned.Just for any of you who were clicking refresh every minute to see the results.(You know, not that I was.)

Can't get these glowing wood and resin chairs that Bright Woods showed off in Milan recently out of my head. I know that some glowing furniture wouldn't quite work in my house, but I really would love to make something like it. So instead I'm putting it out there to all of you. Please do something with this idea and post it here. Bright Woods’ Tables and Chairs Captivate with an Engaging Glow

Ignoring the practicalitites of expense, chemicals etc, would it be possible to paint and ENTIRE room, or at least a whole ceiling, in glow-in-the-dark paint? I'm thinking what would it be like to have an off-the-grid room that would have a useable amount of light, using glow-in-the-dark paint, for say 4 hours after sunset. Can anyone find any pictures of a room painted like this?

Okay, I had this great Idea for an Instructable that would turn a regular retractable ballpoint pen ( The ones you click to open), into one that would light up at the base, using an LED. The Problem is , I don't know how I would Put It together. If you have any ideas on how to do it or any help, you can post them all here. Any and all help is welcome and appreciated.

I have a throwie style LED I wish to make glow on and off. Can someone help me with the electronics here? is there anything I can simply solder on. I need something very small and preferably prebuilt as it's going in a very small container! An on/off cycle would be fine as well (but not as cool)

I was entered in the make it glow contest. First it said it would end the 6th, and then it changed to the 12th and then after that it disappeared completely. It is not on the contests page  but i can access it from my account page where it says the contest is closed, however no finalists or winners are shown, only the entries. Do contests sometimes randomly get shut down? I also noticed that the prizes that were originally listed have changed. Thanks

Here is a free idea for the glowing contest. I don't have the time or inclination to make it, so y'all can fight over who does it if you want.Basically, the idea is just a yellow or pale green led or series of leds that glow in the same pattern as female fireflies, in the theory that this will attract males to your garden or whatever. I know that you are supposed to get rid of extraneous light sources to attract fireflies, but this sounds like it could work to me. Feel free to do it, so long as you give me credit for the original idea in the first line of the ible.Doesn't anybody like it...even a little bit...?

I hadn't even heard of this company before today, and I'm quite impressed with them. Anelace, Inc. makes those lovely binary LED clocks and distributes them to resellers. I got one of their "Crystal Blue" clocks under the Discovery Channel Store name five or six years ago as a birthday present, and recently one of the LEDs failed. Since they're surface-mount LEDs, I was having difficulty figuring out which of the hundreds of items on the dozens of pages in the DigiKey catalog to order, so I quickly found the manufacturer (Anelace) through Google and fired off an email hoping for information about the LED specs. I sent this email at 9:33 this morning. At 11:59, I received a reply from "Lyle" saying that it was unusual for two LEDs to fail in this fashion, and he wanted to mail me a new clock, and have me send back the mainboard from the old one so they could test it. Even after I explained that only one of the LEDs had actually failed, and I had clumsily crushed the other with a too-large caliper, he still wants to send me a new clock. I find this amazing for a number of reasons: Very prompt reply. I'm used to waiting days for customer service to get back to me. Under two and a half hours is phenomenal. Personal reply. This guy actually read my email and responded to it, rather than simply sending back a form letter. Interest in the problem. Rather than just sending me a new one to shut me up, they want to know what went wrong. As Lyle put it, "I'd like to see if there is anything we can learn to improve our design/quality/reliability." This one's the biggie. They want me to take it apart. In a world of epoxy-sealed cases and more security screws than anyone can keep track of, he was even willing to send me instructions on how to pull out the circuit board. I'm not writing this to encourage people to try to bum clocks off this company; rather, I'm writing this to encourage people to support them. Anelace doesn't sell these clocks directly, but there are several retailers that do. Consider this my unpaid endorsement of a customer-friendly and personable company.

Hello everybody! First of all i'd just like to say I just made an account but have been using this site for years and love you guys =] I have this idea for a tv stand / table and I am stuck. attached is a drawing of my table (tried my best). The idea is a table made out of a recycled door as the table top, clear 6'' diameter and 2' long tubes as the legs, a liquid that reacts to blacklight inside the legs of the table such as laundry soap to fill the inside of the legs, and one small waterproof fan in each of the front legs to create a vortex inside the tube. So essentially I want a table with legs made of clear tubes with a glowing tornado in each front leg and a black light mounted under the table to light em' up! I need help figuring out what would be the best / cheapest material to use to create the front legs. Also what type of fan to use that is waterproof and will have enough torque to turn the water. Any help is appreciated!!  

Hello, I made a Zelda-style fairy (as seen in this guide https://www.instructables.com/id/Zelda-Style-Fairy-In-A-Bottle/). I was thinking that I might be able to give the styrofoam ball a little more character when not lit up if I could give it a light coat of paint. If there's a glow in the dark paint I can use for this, even better. I don't want to add so much paint that it will smother the light when it's switched on. I know spray paint will melt styrofoam, so that's out. Would I be able to sort of dry-brush acrylic paint used for miniatures onto it? I have a few pots of Citadel paint on hand, or I can always run to the craft store. Heck would food coloring work? Or is the whole idea more trouble than it's worth? Thanks for any help Dave

I use nitro rcs very often and use glow drivers very fast and want to save a little money

I was making some sodium chlorate using https://www.instructables.com/id/EGXGY5PF23Z375E/, but instead of using some 9v, i put a bridge rectifier on to my AC power (i live in south Africa so 240v) and the I put what i hope was DC into the salt water, which began to glow and made a noise. Why was it glowing and is there any danger to let it run for 2 hours?

I was looking at this year's Make it Glow contest page and I noticed a small typo. The little rules blub on the bottom of the right sidebar lists the contest as open until January 16th, 2014 when the official rules and the countdown list the contest as ending the 6th. It's not a big deal, I just thought I would point it out. In case it for some reason matters: OS: Windows 7 Browser: Firefox 24.0 and Chrome 30.0.1599.69 (tried both)

You know the stuff those glow in the dark stars are made from? Where in the uk can I buy a sheet of that maybe a4 size. Thanks!

I know you can use Tonic water to make Blacklight reactive ice, But can you use this same method on soft contacts? I have no idea on weather tonic water is bad for your eyes, even less whether soft contacts are saluble enough for this trick to work. I figure a mix of 2/3 contact solution, to 1/3 tonic water soaked overnight might be enough to give your contacts a soft glow under blacklight. But I just dont know!Anyone willing to try this with some "overused" contacts?Glow Ice, How-to

Hello!  I have an Arduino Duemilanove running a very simple glowing LED program. I plan to build a small device to house the LED and I was wondering what my options were for using a stand alone ATmega.  Most importantly I need to know how small or low voltage of a battery I can use to power the one LED and the ATmega.  I'm also open to any suggestions that go beyond the arduino. thanks!

Using like a coke plastic bottle or something. Inside the bottle has a colored fluid with letters floating around.

I recently took apart a digital watch that had a green glow type of backlight. Looks like there was a backplate, behind the LCD screen, with what seems two contacts on opposite ends. No matter how I hook up these contacts to a 1.5V battery, I can't get it to glow. Any ideas????

Hi I have bought a LED glow sitck. The type used in cars for "effect" lighting. I am using it  on the back of my recumbent bike. However I think it would create a bit more safety for me if it flashed. It currently runs off a small 12 volt battery. I have looked through instructables to find out if there is anything already written up. However my knowledge is  very limited, so I am uncertain if I could use some of the circuits described. I can solder okay and that is about it. So my burning question is how do I make a circuit that will flip the 12 volt power supply to the LED's on and off. Alternatively are there circuits already on instructables and I just have to build and run 12 volts through it ( and it won't destroy the light stick). I dealy I would like it to flash on and off fairly rapidly. Any assistance would be appreciated. Thanks

How do I increase the glow time of luminol? And what is the safest mixture of chemicals that I can use for chemiluminescence? I'd like to avoid using highly hazardous chemicals like potassium hydroxide if possible. Ideally my mixture would glow for a few minutes once activated.

Alright need some help. im wanting to fill a bunch of test tubes with the fluid from glow sticks for my halloween costume this year. but for some reason after removing the fluid from the glow sticks and putting it in the tubes it does not stay lit for very long at all. im talking anywhere from 3-4 mins to 60 seconds. i have tried breaking the inner container before and after putting it into the test tube, and for some reason mixing the two after seems to have a longer life. moving and shaking the test tubes does cause the mix to glow for less time and im going to be wearing them so i cant have this. does any one have any kind of knowledge if this area? i could really use your help. any ideas on how to fix the life span?

I have a timex expedition trail combo, product number t49742. I want to disassemble it to apply illumination to the dial. Oh, and if there is a way to make the watch's ticks silent, that'd be great. EDIT: Thanks for all the comments so far. I have pretty decent glow in the dark powder, which is supposed to last 24 hours. I've applied it to my knives, as well as other objects, and they are all doing pretty well. The lumination on the timex expedition is pretty weak, and it really doesn't do anything, I need to use the backlight. Sometimes, such as when I'm driving, I want to just look and read the time. So I planned on opening the watch to apply the glow, via epoxy, to the dial.  I've opened the watch, taken the battery out, and that's it. I can't figure out how to reach the face of the watch and access the dial hands. 

Hi! First of all I want to apologize my English but its not my mothers language. So what I would like to do is add warm white led (leds) into my computer what would fade out and fade in like really slow pulse. How this could be done. I can do basic soldering and schematics but the easier the schematic is the better :) And as cheap as possible because I'm not that rich at the moment. I have googled this a bit but found so many different versions and also they all faded so fast and I want my led (leds) to fade slowly. And because the idea is to but them to my computer this project would be using either 5 or 12 volt source. Thanks for all who can help me! Make
