In a dark corner

What do you do when you publish an Instructable that would be helpful to many, but its posting is delayed several days. When it finally appears, there are five pages of newer Instructables and no one ever finds yours in the "Recent" listings? Do you unpublish and republish it, hoping it will get moved to the front of the pile? Does that even work? Do you shamelessly make comments leading others to it in previously published Instructables that are still gathering some hits? Do you just wait until people discover it somehow through using Randomizer and a link or two on Google?

Dark Side Of The Moon? Answered

I have been taught that we always see the same side of the moon.  The other half is called the dark side of the moon.  Is this dark side really dark, or is it really bright when the moon is a new moon?  I know this is a stupid question, but I just wan't to clarify with so many dark sides.

The Dark Side of Crafting?

I was recently sent this update from UC Berkeley and Indiana University, and thought I would pass it along.  I have never had a brush with the "Dark Side" of crafting they describe here.  Have you? Do you sew clothes, print posters, or shop for craft supplies only to realize your craft has negative effects, e.g., on the consumer or society at-large, morally, socially, and/or legally? Do you see a “dark side” to craft? If so, UC Berkeley and Indiana University researchers conducting a research project on handcraft and computing would love to talk to you. We will conduct interviews by instant message, email, phone, or in person within the next few months. To help us with our research, please email Daniela at daniela@ischool.berkeley.edu, Jeff at jbardzel@indiana.edu, or Shaowen at selu@indiana.edu.   image blatantly stolen from pirateluv which just has so many other cool things on it too.

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.

For those in "a dark place"

We seem to be attracting a number of troubled souls at the moment.Without wanting to reject any cries for help outright, most people here are ill-equipped to offer useful, non-judgemental advice.If you are reading this in the UK, may I recommend The Samaritans?I have had personal experience of their services when trying to help a close friend who tried to commit suicide, and I found them to be clear, rational people with a far better understanding of the depressed or teenage mind than I do.Their website is http://www.samaritans.orgTheir email address is jo@samaritans.orgTheir phone number in the UK is 08457 90 90 90Their phone number in the ROI is 1850 60 90 90If you are not in the UK/ROI then they recommend using http://www.befrienders.org/ to find similar help and advice in your country.As I said, this is not meant as a rejection - we will help if we can - but there are people infinitely better at providing suitable, non-judgemental, anonymous advice.If any American readers know of similar organisations in the US, please add links to their websites.

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 :)

Best dark metal for solar absorbance.

What's the best metal for absorbing sunlight? ie, darkest. It needs to be immersed in ethanol, which will dissolve pretty much any paint etc. I've tried steel with some kind of enamel or anodised layer, but the eths started eating that too. Also whatever it was seemed to reduce the heat getting into the ethanol. And are there ways of making metal darker, chemically or through heating? I've been recommended getting something rusty and using a rust converter, which turns the oxidised layer into a phosphate, which is dark and might work well. Also.. are there other characteristics I should be paying attention to in order to maximise the amount of heat transferred to the fluid, like conductivity, emissivity, etc? Cheers.

Any guidance to Filming and taking photos in the dark? Answered

Hey everyone ! I have been using my galaxy S3 for my Instructables photos and I keep running into a problem. When I am able to pour some good light on it, I can take some really nice photo's. but as soon as a try to take a picture of any of my Led projects (in the dark) the quality goes out the window! (I assume because it can't focus in the dark?) I included two of the good photos as a comparison the the Disco ball. **I still need to be able to take shots in the dark, to highlight the Led's / project lighting** Any thoughts on how I could Improve both photos and vid? (Preferably with my cell) I've tried with and without flash, different angles and even focused it with the lights on before turning them off to take the photo.  https://www.instructables.com/id/Simple-20-Disco-ball-with-lights-/ Hopefully someone can offer me some guidance; These Pics really don't look nice >.< (Best answer given in about a week !)

Computer room keyboard light

   I want a dimmable low-wattage led lamp to mount to my computer desk shelf. It will sit above the keyboard, shining diffuse light down but not directly at me.    I could mount it underneath with screws, or have it sit on the shelf above, looking over it.    It'll be powered by 120V 60Hz, so no batteries required.    I have two design problems that I need to solve before I start.    First, I need a diffuse light source that will light up my entire keyboard without blinding me with a direct view. This should be a warm white rather than something bluish or cold, since I don't want to lose my night vision. (I watch movies and do graphics on the computer at night.)    I haven't been able to think of anything that will fit back far and high enough that my slouched posture won't cause a problem. I thought of an opaque diffuser that the light would shine up into, but the geometry seems a little tight.    Second, I would like recommendations for the dimmer control. I want to dim the light right down to nothing, and switch it off, easily and quickly for when I'm stumbling off to bed. It needs to be a bit sturdy to handle my fumble-fingered ways, and quick to find.    I appreciate any suggestions anyone can come up with, and I'll be glad to gab on more about what I want if you have any questions.    The shelf is 28" or more from my eyes when seated at the desk, and about 30 degrees of it is currently blind to me at maximum slouchiness. It sits 6.25" above the desk, and I can easily spare 4" of clearance under it; the only other thing that has to fit there is the keyboard itself with a little wiggle room.

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).

Windows - Monitor turning itself off after a few minutes.

Today I faced a problem that according to my internet research on the tablet is quite costly and annoying. First off my specs for the computer in the basic form: Windows 7 on 32GB of RAM with a decent Nvidia graphics card. Problem: After a few minutes of use the screen suddenly goes dark, like when going on standby but Windows itself still runs as normal. Quite often when it happens the screen brightness goes up to max right before the screen goes dark. Taking out the monitor cable and pluggin it back in usually gives the screen a few seconds until it goes dark again. Official solution as suggested in many forums and knowledgebases: Take check if the problem is the same when using a different video port on the card - checked and it was for me. Check it the fan is working as it could be the card shuts down from heat problems - checked and cleaned the heatsink while at it. Replace the graphics card if problem persists - Why the hell would I do that???? My solution: Take the card out. Clean it with some air, especially the heatsink and fan. If have and old school office using paper and pen you might have one of these fancy easers with a blue part that is really coarse and has some fine particles in it. They were used to remove ink or pen writings instead of pencil marks. If you don't have one take some aluminium foil and crunch it to a small ball. Use the eraser/foil to clean the contacts of the card. The gold plating should come out nice and shiny, if it still looks dull keep working it a few minutes longer. Just rub from one side to the other over the contacts. Once fully shiny remove all debris by blowing it off - pay special attention to the tiny gaps between the contacts!! If in doubt use an old toothbrush (dry and clean of course) to clean between the contacts, a cottum bud works too if you are desperate. Put the card back into the computer and you have a really high chance the monitor stays on and will work fine from now on.
