looking for a light chaser circuit or someting that I can get a string of lights to come on one after the other.

Want to be able to get lights to come and chase each other. Have seen them on signs would even accept a program on the computer that you could use to control them.

What are these lights coming from the hood/bonnet of the Mini?

In this video (it's really short), near the end, the Mini is driving through the woods with dancing horses projected onto the trees from what look like lazer lights on the hood of the car. What are these lights? Can I get them?

Please help!!!!

I am new to the site. First of all I would like to say that this site is great and it has a ton of helpfull information. My question is that on the tail lights of my car I have led lights. It already has the circuitry for to do its job of getting brighter when you hit the brake and it comes back to less bright when you have your parking lights on. The tail light has 2 sections 1) the park/brake light and 2) the turn signal. I would like to make my turn signal section to light up some what dim when I turn on my parking lights and then when I activate my turn signal to flash brighter. Is there anyone who can help me with this? I tried connecting to my parking light wire to see if it would work with a resistor but it did not. HELP!!!!

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

Under Desk Lighting

I'm getting ready to purchase a desk with frosted glass surfaces ( and want to add lights of some sort under one of the surfaces so that I can use part of the desk as a lightbox for sorting negatives and slides.  I'm guessing that a fluorescent fixture of some sort would be best, but I need ideas on mounting (there are rails along the front and back of the surfaces that have around a quarter-inch clearance from the rubber offsets that hold the glass), what kind of light to get and how to wire it.  Anyone have any ideas?

Colored Fluorescent

Hi there, My first time posting here, but have been reading the website for a long time. Recently I have been fascinated with lights and light art. I have been a fan of Dan Flavin for awhile and love the way he uses fluorescent lights.  One question I have is, how do I achieve colored fluorescent lights? I have done a bit of research and a few people have suggested cellophane wrapped tubes, but I'm concerned that this might burn / melt, and may look slightly amateur?  Any help would be much appreciated. I have attached a couple of examples below. L

Led Christmas Lights

I have an idea but have no idea if it would even work. I would like to make a led string that can be two different colors. The idea is that I put the lights up in October and they are purple and orange for Halloween and then as Christmas approaches I can change them to green and white. That way I can put lights up one time and do it when it is still warm out and my neighbors wont think I'm nuts. I know I can weave two lines together and just switch plugs but that isn't complicated enough. I like to do things that are way more complicated than it needs to be but are really cool when they are done. my wife loves it.

Help me build stadium lighting for my foosball table

I work at a little marketing/web agency.  The job is sweet, but the foosball is epic.  We have internal league games among the 15 of us, but we're going to go intercollegiate this winter and the foosball table need some polish.  I think some epic stadium lights would fit the bill nicely.   Here's some parameters I'd like to work within:  * They should look as close to the real thing as possible - no shortcuts when it comes to the aesthetics (Google images here). * They will probably have to hang from the ceiling. * They should be bright.  Not necessarily blinding, but brighter than average.  Definitely not feeble. * I'm thinking 2 sets hanging above either end of the table and safely above head-height.  That probably puts them about 4-6' away from the surface I want to illuminate. * We can probably spend $40-80 on materials.   * I doubt we will be doing any electrical work to accommodate these, so each one needs to run off a single, probably very long, cord.   The real crux for me here is the lighting - I'm really not familiar with lighting.  I'm sure I'm looking at LED lighting, given that I want to have many lights working from a single power source, but I'm worried that after I spread the available watts out over a large number of lights I won't be able to get the kind of intensity I'm looking for.  And I'm wondering how much I would need to spend on the kind of light that I need for this project.   I'm imagining that the frame of the light will be some kind of small diameter metal conduit.  I'm not sure what the best way of linking the conduit together would be though.. Ideas are warmly welcomed   : )  Cheers, Micah

New to LEDs, need to wire lots of them

I've never worked with LED lights before.  I'm putting on a show and I want to have lots of little points of light in space in a dark theater.  I'm talking hundreds of them.  I considered fiber optics, but that started looking way too expensive.  Is it possible with LEDs?  Is it expensive?  How to I learn how to do it?

Led light

I'm struggling understanding what im really needing and could use some guidance... I'm tring to build a underwater fishing light that has 36 3watt green leds.  I'm going to only be powering them when the engine is off and the batteries aren't being charges... it will run off a standard 12volt marine battery... the led specs are ' green (510-530nm):DC Forward Voltage:3.4V~3.8V Forward Current: 700mA'.  what would be the best way to power these leds... im assuming that I need to power in series groups of 3. but with such a wide voltage of 3.4 to 3.8... do I just shoot for the middle? do I use 12v in my calculation or do u use like a 12.5 or 13 like it sometimes checks.... Can I get by powering it with just resistors or do I need a led driver? I have entered my data in some of the calculaters online and it says I need a 2.2 resister but gives warnings... and doesn't say what watt resistor... does it matter... first project ... confussed to say the least thanks

18v dropped to 12v?

I want to limit two 9V battieries, in serial to 12v. I want to run a cold cathode off em, if the strain is too much, I'll join two parralell sets of two 9v batteries in the circuit. Anyway, how do I do it? I can't find any 12V regulators at all, and I don't know what sort of resistor I'd need, is there one that would limit it to 12V, with the standard 9V battery ampage? How could I archive this? Thanks.

Just picked up a strip of LEDs...need a power supply for them

I just bought these by accident (One-Click and I figured instead of returning them and getting my money back, I could actually use them around my room. The only problem is, I'm not too sure how to actually power them. From what I understand, they require a 12V 5A power supply. Is there anything common I might have in my house that I could use to power these? If not, where can I pick one up cheap-ish and with fast shipping? Edit: forgot to mention I own a Dioder kit from IKEA, would it be possible to use the power supply from that? The label on it says 12V, but only .42A so I doubt it.

A sport coat that has hundreds of little lights sewn into it.

I once saw a local musician play the guitar and sing in a small venue. For one song, they dimmed the lights on the stage almost completely, and the sport coat he was wearing suddenly "switched on" and he had hundreds of tiny little light beads sewn into the jacket that you could not see before. They were not string lights, like for a Christmas tree. They seemed to be much more LED like, and bright, and most of all, small to the point of being invisible.  I hate to be a copy cat... but I want to make a jacket like this too. I do not care if it is portable. i.e. if I have to plug it in, that's fine. Anyone have any ideas for where I might start?

staircase handrail lighting

Hi. not sure this is the right category but here goes. i want to build a staircase handrail (interior) that has LEDs underneath it, pointing towards the stairs, and i want them to light up automatically when someone touches the handrail. a nice variant would be that individual lights light up following my hand position on the rail (following you up or down the stairs) and an even nicer variant to that would be to have the other lights fade as you move. is this possible? and is it possible WITHOUT mild user electrocution? :D i have no trouble building it, just not sure about the electrical part... please share thoughts or ideas on how to make this! thanks!

Creating a light from recycled parts

Here is my dilemma. I have a Superman acrylic plastic emblem. I removed it from a former toy and now I have an idea that I would like to make a light out of it. As you can see by the photos, it's not very big. It's length is roughly 2 inches, and I plan to sand the ridge down so it can slide inside a PVC pipe adapter. I have a landscape capsule light, so it doesn't have excessive heat, and it has direct light. I am trying to figure out a way to use all the material to make a light with a Batman Signal light type stand. (See Instructable for the the Batman Signal light) If anyone can assist me or give me some ideas, hints, suggestions so I can put all this together, it would be terrific. I will post the whole thing when I am completely done. Thanks!!!

help wiring aquarium lights

Hi, i'm building a steampunk style ornamental hood for my 20 gallon aquarium, i will be using the florescent lights from two old store bought aquarium hoods and two cpu fans; all to be installed in this new hood. i don't have much experience wiring, i can splice wires with caps and electrical tape. it would be really convientent if i could wire the two lights and two cpu fans to the same power cord and on/off switch. i know there will have to be some kind of converter between the cpu fans and the lights because of the voltage, but what kind and how exactly i dont know. also each the the florescent lights have there own powercords and on/off switches. it would be easy enough splice both light to one power cord but how do i wire them to a single on/off switch? i'd greatly appreciate any comments or suggestions. thankyou.

Undercabinet LED lights from 110v source

Hello, Ever since i moved into my current home I have wanted to put in under-cabinet lights in the kitchen. Its a small kitchen but the current fluorescent lights are just not giving me the light I'd like.  Powering the LEDs is my only concern. There are two under-cabinet areas each with one type of florescent light fixture with a normal 110v power line running into each light directly from a small hole in the wall (all hidden of course under the cabinets). There is no power outlet associated with these two lights. There is one outlet along the wall but I would not like to use this if possible as it powers the kitchen appliances, and it would show the power cord from the lights (Id love for these new LEDs to remain hidden.) I understand to use a 110v source I would need a LED transformer of some kind, I have seen these for sale, but I do not have an outlet that this transformer can plug into. Like this: Is there a way to connect a type of transformer to this direct 110v line? Would I splice the plug off the end of the transformer and just crimp it to the 110v source from the wall?  Like the end of this transformer: Im currently at work but if pictures help I can upload them later. Thanks!

Home made "emergency lights

I'm a member of a Shriners riding unit that makes mini firetrucks and ambulances out of go-karts to ride in parades. Strictly for fun. Many of the guys have spent hundreds of dollars to purchase "official" police vehicle lights but I'm thinking I'd rather tinker and make my own. I can probably do more with them this way then be limited to what I could buy commercially. I'd figure that I can get most of what I need in the way of LEDs and such through Radio Scrap or a local equivalent but I'm wondering if anyone knows of a site with some DIY plans on how to do this?

Need help with LED lights

Hey, I'm making an infinity tunnel/mirror based off an instructable on this site.;=NEWEST&limit;=40 But the instructions are crystal clear and I'm running into a few road blocks. What kind of LED should I buy? They all have to be the same voltage correct? Does it matter if I connect it to a battery pack or the wall? What kind of battery should I use? Basically I know nothing about electronics and I don't want to create a fire hazard. Any help is appreciated.

New device gives you green lights on a bike

When you're riding a bike and you get to a stoplight sometimes you won't get a green light. The sensors don't see you and you're stuck. I usually just ride through anyway, but others have sought ways to get the sensors to think you're a car and give you a green.This new device claims to fix this by emitting a frequency to match that of the inductive sensor.The inventor claims that this is more effective than using a magnet like blacksmith_tb does or Kipkay does. Commentors on the site seem equally skeptical and point out that similar products have already been on the market for several years.As for myself, I don't feel like adding what looks like a decent amount of weight to my bike for such an occasional problem that I'll just ride past anyway. What do you think?

L.E.D. wifi controlled lighting

There are currently 2 different systems in production, LIFX (kickstarter) And Philips Hue - released next year (in the UK) Both systems promise amazing leaps forward in control and ambience, but both are expensive. I think they are going to be a way forward eventually and will re-invent the lightbulb. But not being technically proficient at electronics, has anyone made an instructable or is anyone in the process of making one? I can generally follow instructions well enough, but for the most part this is beyond me to make and design myself.

Need advise with making USB LED string

Hey all, First post and I have an itching to make something for once, I want to make an "Infinite Mirror", I have seen a few instructables on how to proceed, My main concern is that most of them are battery operated, And I want to operate mine from USB, Now I will put 12 lights in a string, Then output to USB , But will I need any resistors, chips ect? or will just wiring up 12 LED's straight onto a USB end work? I don't want them to do anything fancy, Just be on when plugged in. Any help would be greatly appreciated.  Thank you!

Circuit Diagram for LED bulb running on 120V AC

I have been watching a lot of YouTube videos of building your own LED bulb using a scrap CFL bulb. Since I have watched a lot of those videos, I want to build one. However, almost all of those videos are about making one that runs on 240V AC, and where I live I use 120V AC. Take this video for an example: I also noticed that in that circuit diagram, there is a 5th diode that is unnecessary. So I want to build an LED bulb similar to that one in the video above. But I am not so good with electricity, so I am not so sure how I can modify the circuit so that it will run with 120V AC instead of 240V. Can someone help me with this?

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. TIA Danneauxs
