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

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

Brake lights

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.

Circuitry for lighting

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

Vertigo Lights

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!

Lightning lighting

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

Lighted Wand

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!!

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.

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!

LED Christmas Lights?

I'm a freshman in college right now and I really want to spruce up my suite and room a little for Christmas. So Christmas lights would come to mind to display at my suite's door, but because of fire hazard rules/laws we can't have extension cords. I think I also read that we can't have Christmas lights period. So I started thinking I could make something out of LED lights to attach to our door so people walking by can see. I was thinking maybe an outline of a Christmas tree made of green LEDs would be cool or putting LEDs inside a wreath to light it up. Which would be the best way for me to power all of the LEDs? I've never worked with LEDs before, so this would be new to me but I really want to put something together. I basically want to chain a bunch of LEDs together, power them with batteries, and have the ability to turn them on at night and off in the morning. So, any ideas would help a lot. Maybe a point in direction.
