Fairy Lights

Hi I have an idea but dont want to buy stuff and its a bad idea in the end. Now is it safe to put christmas lights in a pvc tube that has drill holes. With an opaque plastic cover. I would like the holes to be of different sizes and in random locations or in a wavy idea. I am not sure of how to mount to a wall horizontally or vertically. I like the idea of led;s because they make no buzzing . Maybe someone got any ideas? Thanks

Reactive Lighting

Has anyone seen the LED lighting in some grocery store freezers that comes on only when you stand near it? I'm wondering if anyone knows of a circuit I could build that i could line my hallways with LEDs and have them come on as I walk down the hall?

Night light

Hi all, I'm newcomer to this "club", and am looking for some help, please. I'm looking for details of how to make a night light, with a rotating element with designs (people, animals, trees, plants etc) either cut out of it, or painted on it. The rotating element is powered by the warm air coming off the top of the globe. The rotating element should be able to be "dropped into" position. Sorry I have nothing further at this stage!!

Hello.

What is the easiest/simplest method of making a flashing light (preferably a small string of LED's or a piece of EL tape) connected to a momentary push switch? no timer or any other complication just lights that will flash on and off until the button is released. i want to make a flashing indicator light and switch small enough to mount on a ring that i can wear on my pointing finger so that the button hits the back of my hand as i straighten my finger to point and the light flashes only until i curl my finger to release the switch.

Flourscent Light Sickness

Every time I walk into Wal-Mart or Home Depot, I get sick because of the fluorescent light. The problem is, almost every large retailer uses fluorescent lighting. I get migraines, and queasiness. It has a great impact on my life. I was only curious to see if anyone else on instructables had such a sickness. If you do have such a sickness, what Do you do about it? My new school has all fluorescent lighting. -sunglasses? -migraine medication? (although that would not do much for the sick to the stomach feeling) I call it Wal-Mart sickness.

Audio Triggered by Light

Hello, I'm an absolute beginner and I would appreciate some help. I need to build a sensor that triggers sound either on Pro Tools/Logic Pro/Garage Band or any other kind of audio software when it detects a single red flash of light on it, much like the light a laser pointer would produce. The light will flash from left to right in intervals of 2.5 or 5 seconds apart. The sound is nothing too complicated. It's basically just single notes, pitched a fifth apart so for example, when the left light flashes, it needs to trigger middle C, then when the right light flashes, it needs to trigger G above middle C. Problem is, I do not know how to go about this and where to start. I would be deeply appreciative if someone could help me out here and point me in the right direction. Thank you!

Spread LED light?

I'm having trouble using an LED to light up a vase. I have frosted a vase and was hoping to get a blue led to light it up from putting it in the bottom of the vase and give it a sort of blue glow, however, it is just not working. I can still see a big concentration of light where the LED is and towards the top of a small vase (maybe 8 inches?), there isn't much light. Is there a particular LED feature I should be looking at? Certain type? Certain voltage? etc? I was hoping the sunjar tutorial would shed some light (no pun intended) but it really didn't help much for my project. I was trying to get an effect similar to:http://www.westcoastmall.net/images/GS68.jpg or maybe http://www.vibride.com/images/photoalbum/38/ostrichfeather.jpgany ideas?

Led light & switch

Hi, I've purchased a wooden toy kitchen, for my daughter. I want to add a couple of special effects to it, for realism. There's one part I don't know exactly how to do and I don't know the correct terminology for the parts I need. So any advice would be greatly appreciated. basically, the pretend oven part of the kitchen, I'd like to add a push to make, illuminated switch to the panel that houses the pretend dials. I want this switch to be connected to a battery, hidden inside the play oven & upon pressing it, not only does the switch itself light up, it powers some red led lights. This is so when my daughter presses the button, it'll light up red inside, to give the impression it's hot, the oven has a Perspex panel, so the red light will be noticeable. I'm unsure how many led lights I'd need, it's probably 1 cubic foot in volume & doesn't need to be overly bright. So what type of push button switch, what types of LED & how many, what batteries and what other components would I need?   Sorry for the lack of knowledge & thanks for any advice.

LED light help?

I purchased an LED anti-aging mask called Illumask. You only get thirty uses and then you need to repurchase. The manufacturer states "After 30 doses, the mask’s LED lights lose a significant level of luminous intensity (irradiance) which results in it being less effective.  Longer lasting lights would drive up the cost, preventing us from keeping the price at $1/dose." They're kind of alluding to the loss of intensity being due to the lights themselves having a short lifespan? At least that's what I get from their statement. However, online a user posted that "The manufacturer deliberately drains the four AA batteries after the initial 30 sessions to thwart users from just RESETTING" (the device) I don't know enough about LED's to know which is more likely the scenario. I didn't think the lifespan of LED's was so short that they'd be losing intensity after only 30 uses of 15 minutes? Or is it likely a battery drain issue? If the battery drain issue is more likely, how do I circumvent that? I'd also like to mod the mask to add more lights to it as I don't think there are enough lights to make it effective. Any help in how to go about that would be greatly appreciated. I was thinking LED ribbon lights would probably be easiest. I'm not sure if I could add more of the same type pictured or if I'd have to go with the larger ones. In any event, I need to figure out what's the more likely culprit in the loss of power. There are instructions on the web on how to reset the device, but if the lifespan of the light is an issue, I don't want to buy the same kind to mod it. Any help would be greatly appreciated.

Polarized Lights and Laptops

I was taking apart a laptop's LCD screen and found that sandwiched between the light source and the liquid crystal display were what appeared to be a vertical and horizontal polarized filter. Why is this? I always got the impression that LCD displays had the polarizers attached to the screen itself. Why would there be an extra set of polartization filters behind the screen? Or... am I just plain wrong in thinking the polarization is on the LCD itself? Could these be the only polarization filters? I have searched all over the internet for the answer to these questions, but I think I am just more confused. If these are extra polarization filters, the only thing I can imagine that they are doing is making the screen darker. Any ideas?

I've been looking at some of the commercially available LED grow-lights, and they're insanely expensive, not to mention bulky and unattractive.

Building a lighted trackball!

I saw a guy at Starbucks using a lighted Trackball with his laptop about six months ago. I should have asked him where he bought it, because I've been searching for one ever since and it's "can't be found!". I even searched at the Consumer Electronics show in January; nothing. Nothing online. So I'm going to have to BUILD one! The trackball he was using had a clear plastic case, and it flashed blue as he moved the ball. You can buy translucent trackball assemblies (for games) where the ball is lighted; but that's not what I'm after. The optical trackballs operate off an internal LED, it may only be necessary to expose that by making a clear plastic, or colored (blue?) plastic case; I'm not sure. Any suggestions or know-how would be much appreciated! I would try to build one if I had enough information. -steve

Is there a way for a simple circuit to sense when a phone line is in use and not cause any line interference?

If someone can point me to a schematic I can build it.There are ready made, but expensive, solutions for sale but the costs are restrictive. Any help is greatly appreciated.

Kitchen: under cabinet lights wire to range hood light

I just removed some halogen puck size under the cabinet lights in our kitchen.  They worked but required to plugged in. Unsightly and I lost an outlet in a high demand spot.  I guess I could start putting holes in the wall and attempt to wire it to the outlet but the damn things don't have an on off switch just plug them in and they are on.  Stupid (they predate my living there).  I did find some nice LED battery powered units that work fabulously for ME.  My wife on the other hand turns them on and then walks off.  Fresh batteries in the morning and dead batteries at night.  Fortunately the one we use the most is rechareable. Here's what I'd like to do but I'm rubbish with electricity and lighting so need someone smarter to tell me how. I want to put LED lights under the cabinets for additional countertop lighting.  I'd like to have them wired into the light in the range hood and controlled by the switch that controls the light inside the hood.  Turn on the hood range light and the LED lights come on too.  It seems simple to me but many things have and not turned out that way.  I assume some sort of transformer would have to be mounted somewhere unless they came built into the base unit.   I'd be open to florescent lighting if it makes it easier. I haven't seen this instructible on the site.  If it is thanks for reading, please disregard and point me in the right direction.  I have the hardest time sometimes trying to find something specific for some reason.
