glow in the dark bike

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.

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 :)

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

GID Vials, Tritium, TRASERS, Powders and Chemicals GLOW IN THE DARK!

TRITIUM! So I get a lot of questions from my post and instructables. Tritium Vials are Radioactive Hydrogen H3, also known as hydrogen-3 is a radioactive isotope of hydrogen. It is contained in small glass vials coated in colored phosphor then encased in glass or sealed plastics. These are commonly seen in Gun Sights, Watches (TRASERS) and some Emergency Exit Signs. http://en.wikipedia.org/wiki/Tritium_illumination Small amounts are legal and for approved uses. Read the NRC guides Typically the Trit vials are small, expensive and dim. The latest GID (Glow in the Dark) Chemsticks, LED's and GID Powders or paints seems much more effective and usable. * Cyalume, as used in a lightsticks, emits light by chemiluminescence of a fluorescent dye (also called fluorescor) activated by cyalume reacting with hydrogen peroxide in the presence of a catalyst, such as sodium salicylate. It is the most efficient chemiluminescent reaction known. up to 15% quantum efficiency. http://en.wikipedia.org/wiki/Chemiluminescence New LED low power requirements and high Lumen or light output have provided many solutions that are low cost, high power and longer lasting. GID Paint or Powders are "charged" with light or daylight sources as with your traditional kids toys or stickers. New products are brighter, glow longer and are now waterproof, have many colors and applications. http://www.4physics.com/catalog/GIDinfo.php Also this is occasionally confused with the chemical illumination. However these paints powders and materials use common phosphorescent materials include zinc sulfide and strontium aluminate. Use of zinc sulfide for safety related products dates back to the 1930s. However, the development of strontium oxide aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to the novelty category. Strontium oxide aluminate based pigments are now used in exit signs, pathway marking, and other safety related signage. http://en.wikipedia.org/wiki/Phosphorescence Hope this helps! 01/2011 - Update Source for Materials http://www.darkniteglow.com/glow-shop/ ERCK www.Candlepowerforums.com Additional Tritium Resources * U.S. NRC: http://www.nrc.gov/reactors/operating/ops-experience/grndwtr-contam-tritium.html * U.S. EPA: http://www.epa.gov/radiation/radionuclides/tritium.htm * U.S. DOE (Argonne National Lab): http://www.ead.anl.gov/pub/doc/tritium.pdf * California EPA: http://www.oehha.ca.gov/water/phg/allphgs.html * University of Idaho: http://www.physics.isu.edu/radinf/tritium.htm

Do people make requests for instructables too? + growing glowing geodes + making your own slime

Hey, I saw a instructible or two featured on here that reminded me of something that has prompted a question in my mind. Is there a typical way that people make requests for instructibles, aside from comments on existing instructables, or here in the forum? Or is this forum the typical place (I haven't scanned through to find out on my own)? Anyway, I have a request that I'll try to lay out here... In a badass local toy/education/science shop, they sell these kits of weird or "gross" science experiments. Like growing glowing geodes, making volcanoes, making glowing slime...stuff like that. The problem is, these kits are a bit pricey, but they DO have an ingredients list on the outside of the box. I took photos of the kits/lists in the store, with the idea that I could probably find info online to be able to replicate the "experiments" more cheaply by picking up the components elsewhere. I haven't gotten around to it, and so I thought Instructables would be the perfect place for people that would do the same thing and share the info to all of us. Specifically, I really want to do that glowing geode thing. Some of the other kits were pretty spiffy too, but I don't have the info in front of me to give you further details. (I'm sure I could google around, and eventually I'm sure I will).

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.

Fluorescent Plants

Recently I presented a science teacher in my school, Mr. Zhang with the idea of growing plants with tonic water which contains quinine to see if they would glow under a black light. Today we saw that these bean sprouts had defused and taken in the tonic water, as a result the bean sprouts were fluorescent under the black light. I first chose the mung bean / bean sprout because I know that bean sprouts are translucent and it would be easier to see the glow, but now I want to find out if the seed will take in the quinine, and if so would the quinine be in the flesh of the plant at all. Another test that Mr. Zhang and I were considering was to use a tonic water in a hydroponic system to see if the plants utilize the quinine. Dr. Paul Williams suggested that I grow fastplants in the dark, because their stem is translucent is grown in the dark. (Mr. Zhang knew him from a workshop he did involving fastplants) I'll be updating this as I continue the study, I'll start growing very soon, as soon as I order the supplies that are necessary. The picture below, is of two mung beans, the one on the left took in the quinine, and the one of the right is normal.

long-term low-glowing light (like a night-light) with a PIR/ daylight sensor using a car battery

Hi Apologies in advance if this has already been asked many times, I tried looking through the archive and couldn't really find a solution to my project idea. I want to know if it is possible to create a long-term low-glowing light (pref with a PIR/ light sensor) powered by a car battery which I could leave in the woods (gently lighting up an ornament for example) and re-charge every couple of months? or even put an off-the-shelf style trickle solar panel onto which can be trailed into a sunny spot. I'm up for building something from parts, soldering LEDs etc but only tried in-car LED strips before straight to the battery and don't know how to source or insert a sensor to light up only when its dark or if someone approaches and preferably not having to charge the battery too often.. In an ideal world it could just sit there and only light up when somebody approaches it in the dark/twilight (do you get where I'm coming from?) Over to you guys! Thanks in advance!

Using modern UV active pigments for indirect lighting?

I am still living from boxes after moving house but I came to a small batch of very impressive UV active powder. This new kind glows in the dark for at least a full night with good visability and usally it sold with the color name "auqa blue" - just don't be fooled by the old style pigments that only lasted for a fe minutes, I am taking about hours here.... The images and videos I tried with my SLR and phone are all terrible, seems they don't really like UV light :( My thought was something like this: Having a sufficient amount of pigment in the top coat of the wall or ceiling paint to allow for a nice glow. Either on floor or ceiling level a row of UV LED's to allow for a quick charge of the pigments, or as an alternative once technology has caught up EL panels in the UV range with a pigment coating. An area of 5x2cm is already enough as a "reading light" for several hours or to illuminate a map during night time hiking trips. Also with the long after glow it would be quite possible to use "light transmission". Here you have acrylic sheets on the outside walls or roof catching the light and transporting it to the inside. So you could use natural light during the day that would also charge the pigments on wall or ceiling. Of course this is not really feasable for home use unless you don't require any sleep but tunnels, bunkers, mines and such could benefit especially if using fibre optics to "transport" the light to where it is needed. Another great idea (at least I think it is) would be to use these pigments on footpaths and sporting grounds. Imagine a footpath that glows at night and illuminates where you go! Or imagine a big factory during a power outage at night having clear walkways to direct the workers showing up all of a sudden on the floor... Some quality pigments still allow for over 200 lumens after 60 minutes of recharge - this is in the region of a low power LED of modern technology. I don't think a topic like this will qualify for a best answer but I would love to hear your thoughts and ideas on the topic of these modern after glow pigments.....

UV LED strip light troubles

Hey ho,I rigged up a lighting display for some glow-in-the-dark memorabilia, using a 12V 5A power supply adapter (intended for LED strip rope lights) and some 5050 LED waterproof strips (trimmed down to 156 lights). I asked around and was told I didn't really need to add resistance so I just soldered them cleanly into the display and added an AC power switch between the plug and the power supply.Everything looked fantastic for a few weeks, but over the last few days they seem to have faded... they are much closer to a mild, neutral white than the strong UV-only brightness they originally provided (fluorescent colors popped, GITD toys glowed nicely). There are a few places on the strips that have come to illuminate with a warmer, yellowy light. Before I purchase some new ones and prepare to replace these, is this a common issue with cheap light strings, or possibly something in the power supply I should check first? Do I need to add some resistance between the power supply and the lights?Thanks! -Spunky

What counts as "building" a flashlight? (flashlight contest)

I have a question about the flashlight competition as I don't find the rules very clear. I'll try to explain my view of the rules through some ibles that are entered. In no way do I wish to judge the  coolness, build of the ible nor the ible itself so keep that in mind. I also don't mean to target these ibles in any way I'm just using them as examples. If they are following the rules of the contest I wish them the best of luck. My question is: "as we need to use or build a flashlight what counts as building one?" For example the illuminate your fingers ible . Can this be considered a flashlight? I mean it ofcourse lights up in the dark but can it be considerd a flashlight by just lighting up the dark? Another example is the steampunk Aethersaber . It's a sword that lights up. Is it a flashlight? My last example is the recharge your glow-stick ible. Can a glow-stick be considerd a flash light? So that's basicly my question. Do these ibles count as making a flashlight or not? I'm currently building a project of my own that I hope to get entered before the deadline. And in that project I'll be using a flashlight without any modding so I guess that one is pretty safe. But I also had some cool ideas that involved leds and normal light bulbs. But I don't think the ible would be any good then for this contest. But after seeing the ibles I use above I'm not so sure anymore. That's why I created this topic. Regards, Michel

I made a nifty invention that generates light...what do I do with it? Answered

 Ok, I was tinkering around with some  interesting materials today and I invented a strange thing. It's a chunk of greenish resin (impregnated with certain chemicals) about the size of a soda bottle cap. I was shaping it with an electric sander (it had sharp edges), and I noticed it gave off dim green light wherever it was touching the sander. I decide that the friction/heat generated by the sander somehow made it give off light... So I went to a dark room and dropped it in a beaker filled with water I boiled in the microwave. AND IT LIGHTS UP It gives off a pretty bright green light. Not bright enough to read by (unless it's big text), but easily bright enough to navigate a cluttered room. I dunked it in cold water...and the light practically turns off. It seems to get brighter the hotter it gets. I hit it with my torch, and it lit up REAL bright, and then "turned off" (that particular sample doesn't work now :S) What should I do with it? Anyone have ideas for possible applications?

Funky Ball Challange

Funky Ball Idea. I had a crazy idea pop into my head last night.  These things happen. I call it Funky Ball.  I am not quite up to the task at the moment as I have my hands full of several other projects. I consider my ideas "Open Source" so hope someone with more time and talent will find this a challenge and run with it!  The only "Licensing" condition, post pictures and a video here and let me copy them to my personal project page. Here is the idea posted on my site. ------------- Here it is here ! ( same thing but I might update stuff on the site later ) --------- This idea came to me...I have no idea why. A transparent or translucent ball with illumination inside so there is a glow when seen rolling down the sidewalk. The tough part. Only one side glows! The tougher part. That side is always NORTH !  ( or South depending on your politics ) So here we have a ball rolling down a dark path with the same side always illuminated.  It should appear as if it is floating down the path because the illuminated side never changes position. Options: One color on NORTH and one on South. Perhaps color changing RGB LED's? Perhaps a "head light" always illuminating direction of travel with a tail light. The illuminated side is always the side in the direction the ball is rolling. Methods: Arduino and compass  or gyro/attitude shield? Anyone ?

 hey me and my friends were ton a project of automatic switching of a street light depending on the brightness in the surroundings. so we decided to use an ldr(light dependent resistor). here in this circuit ldr has low resistance in brightness(only few ohms) and very high resistance in complete  darkness(nearly 1M ohm).so the transistor Q1 becomes on in day times and Q2 becomes off and hence the relay remains in NC(normally closed) state and the lamp will not glow. at night the transistor Q1 becomes OFF and Q2 becomes ON and hence the relay goes to NO(normally open) state and the lamp glows.and the sensitivity of the device can be varied by adjusting the potentiometer  now i just want to know are there any defects in this circuit so can u please help me in knowing the drawbacks and correcting them and i want to know whether i can connect a relay in place of a fuse as shown at bottom

IR triggered LED strobe

hey guys, im looking to build a IR triggered LED strobe. in the smallest possible size i can. it doesnt have to be from scratch so if anyone knows of a cheap trigger on a toy i could use that would be great. im looking to build an IR triggered strobe for an airsoft gun i have. the idea is to strobe an led (most likely a UV LED) every time an airsoft pellet trips the trigger. these pellets are glow in the dark so in essence i will be making my own homemade airsoft tracer system. these units are about $70 so if i could do this for free or much cheaper i would be thrilled. i know there are things out there i can use but im drawing a blank right now. i have makers block or something. here are a couple links to YouTube vids that explain the concept and more along the lines of what it should be like. at about 1:50 in the top video theres is a good demonstration on its workings. <br> <br> any part suggestions or ideas would be awesome.

i found a metal rod inside a duracel battery, whats it made of?

After looking through (literally) some batteries that i had held onto in the hope that theyd contain carbon rods for elecrolysis. i discoverd now what the signs are that a battery contains a carbon rod, and how to tell if its a wet cell. now, i opened up a d size duracel wet cell, that contained a metal rod that looks identical to a blunt nail, and i was wondering, what is this made of? because , i kno theres a reason iron rodsa arent used inside these batterries, being because theyd rust, yet this has no rust at all, so im wondering wjhat is it? also, ide thought ide emntion it was attached to the negative terminal. also, is the silvery metalic flaky dust stuff inside the paper roll inside said battery pure zinc? or is it zinc oxide, because ide very much like to try to use it to make zinc sulfide for glow in the dark plastic, so would it work?
