Hi there, I am renting a place for my new office for 3D animation and I wanted to make an automatic lighting system to turn on lights when I'm in a room and off when I move to another room. How easy/hard is it to do that? And what do I need to make my light switch on and off slowly? Cheers, Shawin.

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?

I have a rope light that runs on a battery pack that holds 2 AA batteries. I want to use these lights to outline my grill on my truck. Is there a way to hook this up to the 12V electric system of the truck so I dont have to use batteries all the time?

So i have a '95 chevy suburban, and it has a few issues. at the moment, the biggest issue is my brake lights. Basically, when the vehicle is in accessory and i depress the brake peddle, my brake lights come on, YAY! but when i have the vehicle running and i depress the brake peddle, the 15 A fuse blows and the lights go out. now i have a schematic diagram for the whole vehicle (in parts), but im still trying having a hard time finding where my problem is. im sure there is a short somewhere but it is just all really confusing to me. thanks much in advance. note: night time lights work as well as all turn signals.

Posted by dancan 6 years ago | last reply 6 years ago
Hey all, I have never really done much circuitry to this date, but I was hoping to make a fairly complex lamp that may require a good dose of it. What I'm looking to do is wire four cold cathode tubes (12V, the kind that are used to light computers), as well as two LED lights with arduino based flicker control, and run them off of a wall socket? The pictures are a (very) rough sketch of the setup, as well as a supply list. Is there any way someone could explain what this might require to me in baby terms? All the best, Adrian

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

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!!

A few years ago I was attending a Halloween attraction where a conversation started about seeing a red skull. We asked a few of the actors and I got the name of the attraction's special effects person. What we were seeing was a programmable sheet of red LEDs that would flash so fast that you could only see the after image. The F/X guy called it Vertigo Lights. I understand the concept, but wondered if anyone has come across anything like this. Could this be controlled by an arduino, or would a program need to be written to control all of the lights simultaneously? I haven't been able to find anything like it in any of my searches. Any clues would be great!

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

So, I've had an idea I wanted to try and make but i have no experience with electronics and was hoping to do it all with hardware only, no software. The idea is this, I have a wand which has an LED strip (like a lightsaber, but a lot smaller) which connects to two buttons/switches. First button/switch if held down it will pulse/glow the LED at the base of the wand (charging up spell) and when you release it "shoots" up the LED strip (like you're firing a spell). Second switch just lights the LED at the tip of the wand, making it like a torch (LUMOS).Any ideas on how I could achieve such a feat? Point me in the right direction? I have knowledge on how to solder and such and have taken very basic electronics. Currently trying to make a lightsaber, hoping to get some experience so I can make my eventual goal, the wand. Most of the instructables I've seen so far have been very simple with a single LED at the end.Any help would be greatly appreciated, thank you!!

I would like to create lighting for my art booth using LED lighting strips. I have already worked with these and really like them, but never in the size I would need to light my booth. Everything I have done, was powered but 8 AA batteries. Example of a lite booth, with conventional track lighting. http://jwallacephoto.com/blog/wp-content/uploads/2008/08/2008-04-booth-paseo.jpg My idea is to light my 10x10 booth with 3 10' lengths of aluminum angle iron http://assets.overclock.net.s3.amazonaws.com/9/91/913173c2_vbattach89423.jpeg and put two 10' strips on each of the 2 inner surfaces (inside the L shape). So I would have a total of 60' of LED strips. I need to illuminate 3 of the 4 walls. My first question, would this be too bright? If so, would a single row on each piece of angle iron do the job? Second question is connecting it together and powering it. My only option is to run it off batteries, because not all events have easy access to power and the ones that do, charge a hefty fee. I need something light weight to carry, I don't want to go with a car battery, but feel with this many lights, I might have to. Considering they need to be run for at least 8 hours. But, I really want each 10' section to be self powered and contained. So that I can hang it from inside the tent and not have to run wires all over the place to power the 3 sections. In a perfect world, each one would self powered with a single battery box attached to it at one end and at the other would be a short wires to connect the top and bottom strip inside the V grove to make it all one piece. Making it a 20' length in one 10' section. Anyways, it's late and I think I am starting to ramble. Any help is greatly appreciated.

I am considering doing a project that will allow me to voice command a HTPC for other things then the normal HTPC stuff... for instance.. and yes i kow this is kinda out their on the geeky side.. but my brothers and sisters here would approve... I want to be able to walk into a room and tell the "ships computer to go to Red Alert" and have a red LED rope light hidden behind a false crown molding start to turn on and off.. and also play the infamous star trek red alert sounder..... This would be only one of many things i want to do with it.. but the only example i could come up with at the moment... If you can point me in the right direction for the lighting control done on the cheap that would except commands from lets say a batch file or what ever.... Charles

Hi all. I am wanting to get into using led lighting for long exposure photos (for the purpose of thermal imaging) and I am looking at RGB LEDs for providing the colour. My question being, should I try finding LEDs that have similar light output in mcd or stick with RGB LEDs? The reason I am asking is when I am looking at specs, the green seems to be 2 to 4 times as bright. Is this an issue? Also, the RGB LEDs seem to have a much wider viewing/ lighting angle. I am not sure where to go from here. Any help would be appreciated. Thank you all very much for the time. Professorred
