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.

I would like to build a led light that has 5 white, 2 red, and 5 blue leds in it. i would like it to have a 3 way switch but it can have what ever you can work in to it. i am very new at doing this so the instructions would have to be very easy and simple. please try to keep it small and cheap please. thank you
Question by lynx66 | last reply
Ok so I used to have this key cover that had a tiny light, kind of like those crappy led key chain flashlights except that it actually fit on to the key. It would light up by pressing a button while trying to find the keyhole to put the key in. It was actually really handy.... I'd like to make one myself now that its broken but I'm horrible with electronics and would probably manage to blow something up without knowing what I'm doing. Can somebody make me an instructable for this?

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.

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

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!
Topic by ThePolrBear | last reply
OK I got one for you all! What I would like to achieve is a realistic lightning effect for Halloween displays. I've tried some different ideas, but none can give me a realistic effect. Most produce a timed effect (2 sec on, 2 secs off, 2 on, 2 off etc...) What I think I would need would be a circuit board or something like that, that would produce a random current to a strobe light source (ie. 1 sec on, 3 secs off, 2 on, 6 off, 1 on 5 off etc...) Could this be done? I've searched all over the internet and haven't been able to come up with anything. Thanks! Wes

Topic by slaps123 | last reply
Hello everyone, i have a question and i think people here on instructables are best suited to help me! So i wanted to connect 21 leds together to make a bigger light. I would connect them in parallel and in series (3 in series 7 rows :P) and i thought i would use a 12v 7Ah battery to power this thing. The problem is i also wanted to use an arduino so they would turn on automatically but it can not output 12v. So is it beter to use the arduino to phisiclly controll a switch to turn the leds on or is it possible to power the arduino and then output 5v to the leds. And if it is will they be dimmer? or will the system draw more current killing my battery faster? Thats my problem and i hope someone here can help me. Thank you in advance.

Question by hollywood4l
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

Question by frankentrike | last reply
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!!

Question by dvdpr | last reply
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.
