Sodium Glow

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.

Glow stick guide

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.

Nitro Rc Glow Plug onborad glow plug ignition

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?

Make LED glow slowly? Answered

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.

Glow in the Dark collars for Kitties

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 :)

LED glow tubing question?

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

Free idea for the glowing contest

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...?

Custom Glow Table: need ideas!

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!!

using glow stick fluid outside the stick help

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?

How to disassemble a timex expedition?

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.

Glow in the dark paint for styrofoam balls

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

will any of the these batteries be strong enough to make this nichrome wire glow?

Hello, am currently trying to construct a disposable device that requires a power supply adequet to make up to 4cm of nichrome wire glow , and use as little space as possible. however, currently i am having a small issue as the output strengths of small batteries seem to be unpredictable, and i dont know wether or not these small lithium batteries will produce enough output to get my nichrome wire glowing, for instance, i have a sub c rechargable battery for starting my nitro powerd rc car's glow plg, and it says it produces 1.2v and has a capacity of 2000ma, and it is so strong that it burns up my wire immediately, but then i use my single 1.2v 3000ma rechargeable aa battery, and it doesnt do squat, now why is that?, obviously i know the glow plug battery is meant to discharge faster and allow for more power than AA. what i want to know is, will this small 1/2AA battery be enough to make this nichrome wire glow, which i might add that can be made to glow red hot with a ni-cad 4.8 700mah battery pack. and burn out with a 9v battery. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item;=310101398351&ssPageName;=ADME:X:RTQ:US:1123 this is the battery i am looking to see to use in my device, as it is small enough, and appears to have enough amperage and voltage to be able to burn the wire, but still, as i tested out with my other battery, i cant really tell without actually having it, and i dont plan on waiting 3 weeks to test out the battery. http://cgi.ebay.com.au/NEW-3-6V-1200mah-1-2AA-ER14250-14250-Lithium-Battery-/200535000934?pt=US_Batteries&hash;=item2eb0d14766 otherwise, if this alone cannot burn my nichrome wire, are there any batteries out there that are cheap (especially in bulk), are not much larger than this battery, and have a fast discharge rate, or, if there are any very small basic circuits i can use with this battery, to increase its output to enough to burn the nichrome wire, as i dont ant to exeed the size of a large cork, or roughly or (3x2x2) +/- 1cm3 lastly if i buy a smaller diameter wire, such as this one will a AA battery be enough to burn it? or the 1/2AA http://cgi.ebay.com.au/Resistance-heating-wire-Nichrome-40-awg-100ft-/170454797490?pt=LH_DefaultDomain_0&hash;=item27afe5ccb2 does the amount of ohms per meter mean it will get hotter with lesser power i have considerd using very low voltage incendary light bulbs, however due to the fact i want to make alot of these devices whiches name i will disclose, i find that they may cost me alot more, than what i could get for nichrome rocket wire. whoever answers this first , will get a "best answer" from me.
