How to Lit a 1watt LED using a NOKIA charger

I would like to lit 1w Power LED using NOKIA Charger. Mostly, a 1watt Power LED's specification is 3v0~3v4 DC Volts and 350mA Current. Printed specification on Charger Cabinet it is for - Input 100/240v 50~60 Hz…„ Output 5.7v/800mA. For Series Resistor's Value…„ if we calculate upon Ohm's Law - for VoltageSupply, Vs 5.7v…„ ForwardVoltage, Vf 3.3v…„ ForwardCurrent, If 330mA to lit single LED. In Result we can use a Standard Value of Resistor 7.5 Ohm and because of Resistor's Power Dissipation 792 Milliwatts, can use a 1watt. In series I planted 10 Ohm 1w Resistor instead of 7.5Ω. LED lit up in normal. Neither too much nor too little shining. But…„ about two and a half hours later it was flashing. I switched it's off and checked that the charger unit also became hot. Where I made mistake…? Please HELP how to lit this 1watt LED using this NOKIA charger. I also have one another charger with printed specification on cabinet it is for - Input 100~240v 50/60Hz…„ Output 5.2v/400mA. I also want to use this for one another 1watt Power LED to lit. Please help for this too. please ignore my  bad english.

Get Lit: 10 Great Lamp Instructables

One of the greatest DIY projects to try out is the lamp. Everyone can use a good lamp or two and here are ten different approaches to bringing light to the darkness. Redo the ideas exactly, tweak them, or even mash them up. As long as the result lights up your life and makes you happy it'll be worth the effort. Mad Scientists Light by tim-1138 The perfect touch for that lab you've been dreaming of putting together. Japanese lamp from recycled materials by PKM Put a bit of scrap materials together in this clever way and you'll be able to add a touch of class to your den. Big lamps from Ikea lampan lamps by daan These lamps are quite plain on their own, but start putting them together and you can make something amazing. Universal lamp shade polygon building kit by dan This classic Instructable uses only one cutout shape to create and extraordinarily wide array of lamp shapes. Geometric Cut Paper Table Lamp by drips Start cutting up paper to create a lamp and you'll soon see that the possibilities are endless. Keep experimenting with shapes and sizes to get the light you want. Paper Wall Lamp by naedhi One string of rope lights and a slick use of paper to diffuse the light creates a nice modern lamp. Again, you can tweak the design however you want. RGB Color Controllable High Power LED Room + Spot Lighting by dan Want some bright lights and the power to create whatever color you want? Then take the plunge into high power LEDs and see how much fun you can have. Small eco-footprint living room light by marc_alain Instead of just saying it's green, this Instructable even provides a life cycle analysis. Either way, the lamp itself looks good enough to build even if it wasn't super efficient. Audio Visual Art....FOTC Style by scooter76 Make some art and light up the room at the same time. Don't care much for the New Zealand duo? Then put whatever you want on there. Night Stand Charging Station Lamp by drocko Function meets more function with this lamp that does double duty as a charging station for all your electronic gizmos.

Lit bubble columns/bubble wall

I've been looking at these awesome bubble columns that are so wretchedly expensive and dying to get one for my office. Note, I am sure they are worth every penny, but I have few pennies. For the link-phobic, a bubble column is a clear tube several feet tall with an aerator making bubbles and multi-coloured lights from beneath the column. Some columns are interactive and others have plastic fishies or balls that sail around inside.  There is also a space-saving "bubble wall" that only runs 1L of water.  Anyone even have a clue as to where to start? No pics, sorry, I didn't want to pull them off the website.

Using Edge-lit LCD's LED array

Hi everyone! Recently, a friend of mine managed to crack the LCD of his laptop. While he got a replacement, I took his old LCD screen apart and salvaged the LED array which edge-lit the screen. Now my question is, is there a way I can power this on? There's no information printed on the LED array about its power requirements and I'm looking for any hints / clues I can get. I've attached a few closeups of the LED array, hope to get a lead on this. Thanks in advance!

amount of wind (input) = number of LEDs Lit?

Good afternoon, Im making an exhibition piece that will have children working a set of bellows that are connected to a (pretend) blacksmiths forge. What I need to represent is the more the bellows are pumped the more the "embers" will glow. Im thinking a turbine tachometer that leads to an LED driver set to display as Bar so the faster the turbine spins the more LEDS are lit, or they trigger a series of LEDs to light (this thing has to get pretty bright not sure one LED per step will do it. Trouble is im good with the theory and pretty good with the practical its just the technical that is letting me down. If anyone could see there way to giving this some thought and maybe doodling a circuit diagram / shopping list that would be awesome.

Hi all, new here but love everything I'm looking at here. Great ideas. I'm a Halloween fan, and build my own Halloween props. Right now I have built some cemetery fence columns, and I want to put a fake electric fire on top somehow. I have a plastic candy dish with light up eyes, and I want to have an electric/battery powered flame for the top of it, something that will show up really well at night. Real fire would be good, but I don't want to melt anything. The first image is my column, the second image is what I'm looking for, I just don't want to spend $60 on a couple of them, I would prefer to build them myself. Hopefully someone will give me some ideas....thanks

need help with an led string for a lit up version of cornhole.

I'm trying to build a lit up version of cornhole using plexiglass. I'll need a string of 140 something led lights on one circuit, for the outer perimeter. they just need to be lit solid and hopefully be able to be powered by a battery. then I'd like to have another string that will operate when triggered by a bag that goes in the hole. I want them to strobe leading up to the hole with 27 leds running up, then a group of leds going around the hole operating as the last running light. these would operate only after someone scores. I know next to nothing i need to know in order to accomplish this. Does anyone have any advice for the 140 something string first? Probably best I start with the easy stuff. I need a lot of help here, but I'll really appreciate it. When I say I need a lot of help I mean, I even forgot the basics as in resistors and voltages. I'm using 5mm leds with a max current of 20mA Continuous, 50mA peak for 10% Pulse Width.

Old LCD Monitor converted to a light panel - how do I keep it lit?

I picked up an Acer LCD monitor that has a fault in the panel. I've stripped the panel off and want to use the remaining LED-lit screen and diffusers as an illumination panel. The panel turns on fine, but when the control board senses that there is no video source attached, it shuts the backlight down. Is there a way of 'spoofing' an input (it has VGA and HDMI ports) so that the control board thinks a monitor is connected and keeps the backlight on?

Really Cool, Solar Powered, Balloon Carried, LED Lit, GPS Tracked Project

Hey everyone! I have this pretty sick idea for a project, but I need some help with the details. Basically, it's a cube tied to a balloon, and inside the cube, there is a GPS device, back up batteries, LEDs (sticking out through the sides), a noise maker (the one from Make Magazine #14, will explain later), a cell phone, a cell phone charger, and instructions. Also, I will hope to have the cube be solar powered. So, what I will do is send off the balloon with cube attached, and the wind will hopefully bring it to someone, but if it doesn't, not to worry, the LEDs and noise machiche will catch peoples attention. When someone finds it, they will read the instructions, and continue the chain. Here is what I need help with, having basically no electronics skill: 1: Where can I purchase balloons that are really thick? 2: How will I make the cube waterproof? 3: Right now, I'm pretty sure that the smallest trackable GPS device is a cell phone (being tracked by Mologogo). Is there anything smaller/easier? 4: Would a solar panel be able to power everything in the cube? 5: How can I wire it so the batteries can power the cube when there is insufficent light, and the solar panel can charge the batteries when there's light? 6: How do I put it together? 7: Is there anything I'm overlooking? 8: How's your day going?

To amplify the voltage I use a DC Boost Converter 2A power supply module MT3608 where the module output voltage can be adjusted.The temperature sensors it for hot side and cold side of Peltier element. A good size to have on the hot side is about 3 times as big a heatsink than on the cold side to don't find that both sides are getting hot.

Hi, I work for a small theme park. A third party company built one of our new holiday displays.  It consists of 45 large 'ornaments ', each lit with an AC bulb. I've been asked to provide a way to control each one independently and create a pattern which will repeat.  Sometimes only one bulb is lit and sometimes up to 7 are on at the same time.  The problem is I'm looking at 45 AC plugs!  My thinking is to buy 45 solid state relays. Then can I hook them up to an Ardiuno? I know very little about Ardionos. Which model and how many? I would truly appreciate it if someone could help me get started. Thank you

Will the battry just take 2A from it? If not I have the transformer that came with the Alarm, would that be safe to charge with? It's 12v BTW. Thanks. Never can be too careful. Also, I'm using it on a scanner light tube, this will be fine, yes? I have the starter, it is not a problem. It's weird though, when it is lit, you can pull out the ground on the light tube, not the starter and ut still stays lit. Weird. Thanks in advance!

So I was planning to put 8 LEDs (One for each station/person) And at one station there would be an Push button. I want one LED to be lit up at a time, and when the button is pushed, I want the power to transfer to the LED to the right of where it previously was. Again: I only want ONE LED to by lit at a time. I'll include a basic pitcure for a visual. I think I'll need a demultiplexer and a counter, but not too sure how to use them. thanks, Jusstice

But rather, it's a small pad, about the size of a note card (3x5") that is flammable and completely burns.
