This is my first instructible so please go easy on the comments, thanks.
In this instructible i will show you where to find LED Lights...
(not in shops)

Step 1: Finding LED's...

Dunno Wat To write, by the way just to say, throughout the steps i will just put pictures on, just to show u where u can get leds....

keyboards Have LED Lights !!!
Wow, who here thinks if you can remove LED's from a PCB, your probably smart enough not to touch much else? just a thought, and besides, if they want to be a live test subject for a taser, I'd love to see that one on the news....
When I was 9 (mid '80s) I used to dismantle my my 19&quot; B/W TV and pull the capacitor and shock my older brother when he was sleeping after a long day of sibling abuse.<br><br>He'd leave me alone for a while, at least until he forgot how much it hurt.
I bow down to your ingenuity in sibling torture, wish I had thought about that hahahahahahaha.....would have done good with all them swirlies and atomic wedgies....
<p>My dad to do that as a kid, With a 300V Electrolytic Capacitor!</p>
May I share the Almighty Massive Toe Pound? When in close contact, grab your opponent's foot around the toes and squeeze. Proceed to pound the crap out of the exposed digits. It doesn't hurt but it's VERY ANNOYING and your victim will scream anyways for fear of implied damage! ;.P
I'll admit I laughed! xD <br>You are the Payback Master! :D
Remotes have IR LED's, You cant use those for regular projects...
<p>Ebay has 100 white 5mm LEDs for &pound;1.15, 100 assorted LEDs for &pound;1.75 (yes, all the way from China). </p><p>Still, right from my childhood I learned a lot from taking things apart. </p><p>Sometimes I even got them back together again.</p>
i have found quitre a few interesting sites. just by reading the comments.
just out of interest, how do you safely discharge a CRT tv before working on it?<br />
You get a long metal rod with rubber insulation on one end. <br>(make one by wrapping whole bunch of insulation tape on one end of it) <br>Flip the TV and remove the case.(wear rubber gloves if you don't want to be like me) <br>Now it's time to use that metal rod,just poke around until you hear loud bang. <br>Don't worry,it's now discharged. <br>(if you just want to get LED from it,not scrapping it,find a big capacitor and touch both leads with insulated metal rod from above) <br>Or if that TV is broken,just throw that into water. It will discharge whatever is on the TV,making it safer to work on.
To discharge a crt you need to remove the topcap This is the thick normally red cable with the plastic disk on the end... If this scares you use a pair of insulated pliers ..some have hooks so you may need to do a bit of wiggling to get it off<br /> Discharge the metal end to ground just incase it's charged<br /> You need 2 screwdrivers with insulated handles make sure you DO NOT touch the blades place 1st&nbsp; tip on the aquadag..the silvery/black stuff sprayed on the back of the tube 2nd screwdriver blade onto the blade of the 1st and touch the crt topcap on the tube &nbsp; if charged you should get a healthy spark 5 to 10mm long. do this a few times over a minuite or two to be on the safe side seeing that your new to it<br /> REMEMBER THIS IS A CAPACITOR AND WILL RECHARGE UNTILL FLAT<br /> Hope this helps you Rog<br />
Remember to work with one hand; that way electricity does not flow from one arm to another and kills you. No waranties, ok?
ooo i thought this box was called as a monitor.. :P <br>
itll be cheaper to get some leds from the store than to break all this sh*t up..
Canada too. It is cool
An excellent Instructable; THANK YOU. You have helped remove mystery from LED's, the light of our immediate future. <br> <br>On another note, it's a shame that we have to say things like &quot;go easy on the comments&quot;, but I know what you're saying. INSTRUCTABLES should be more stringent on the &quot;be nice&quot; comment policy. <br> <br>There are clods that seem to prowl the internet, looking for opportunities to make somebody feel badly. For the most part, they appear to be folks who don't feel good about themselves and who get some satisfaction from being an a**hole to someone who is only trying to share knowledge. <br> <br>A smaller number are clods who rely on what they think is a command of the English language (there's one example in the comments below) to feel superior. What they don't seem to get is that some of the most brilliant people on the planet either don't have English as a first language or, are way more intelligent them in other ways. <br> <br>To all those people, I say, &quot;STFU and let the people who have both knowledge, and have the decency to share their knowledge, to do it without your little adolescent need to make other people feel badly. <br> <br>Again - thank you for sharing - and please go through life ignoring the small-minded snipes like the ones who take potshots at people who post on INSTRUCTABLES...
Infrared LED does not gives off VISIBLE lights, to human naked eye.
The only LED's I recycle are the Xmas Lights and then use them to make my Grow lights...Mainly the RED and BLUE ones as these are the colours that plants require for GROWTH and FLOWERING.. I also use the White Light but not as many..................
I probably wouldn't personally put that much time or effort to gleen a few leds. BUT SO WHAT! If some of these folks have the time or inclination to do so, GOOD FOR THEM. Less in the land fill, Etc. Why is everyone so critical????????
My main source of LEDs is Christmas lights. Very tuff, very bright, some have pretty lenses, and CHEAP! I just picked up a box of 120 (2 strands of 60 each, 15 feet long, multi-color) for $8.95 at BigLots. <br> <br>That's less than 8 cents each! <br> <br>You also get a couple of free spare bulbs and free holder/sockets, with connecting leads.
Those flash units are handy in themselves. They take a battery or 2 and turn it into high voltage and fire the flash tube.
They have laser diodes (perhaps you could mount them on sharks!)
Are you referring to the laser diodes inside CD drives?
they are high powered red LED's
Maybe I am kinda dumb but with Led's costing next to nothing, why wld I wanna go through the trouble of prying open stuff to get out an LED?<br>Or am i missing something here?
This is a monitor ,not a computer.However the big box thinggy also have at least 2 LEDs!
Regretfully, unless you are living on $5 a month, I don't think harvesting LEDs from the items you have cited is worth the time involved. You also have the issue that most of the LEDs you would gain from this equipment are only intended as indicator lights not illumination.<br><br>PS: If you really did mangle a DAS keyboard, can I have rest of it? Seriously.
tvs have a TINY very dim and almost usless red led in them . considering the very high risk of a 40 KV electric shock its not worth it . oh and tvs cathode ray tubes store charge for up to 18 months since they where last powered on (so dont go telling me you turned it off.
thank you!
wouldnt discharging the caps with a screwdriver or something cause it to be safe enough for handling though?
The actual CRT itself is one large capacitor, there is a coating of graphite on the inside of the tube neck, and one on the outside, with the glass in between forming the dielectric layer, so make sure you also discharge this too. See: http://www.wikihow.com/Discharge-a-CRT-Monitor<br><br>Better still, find a less dangerous source of components!

Unless you're *really* short of money, it may just be cheaper buying LEDs in bulk from one of the many Chinese component suppliers that are springing up on eBay. Still useful to know for environmentally friendly recycling.
I like this forum!
the best thing about old crt's is the heat sinks and the screws and micra washers,ive got all mine for the last year out a few crt's that were going to the tip anyway. It's often in one big section you can just cut it up.
The best place i have found is a string of LED christmas lights. I bought a string of 100 for 5 bucks at home depot
old telephone generators work very well on siblings,and chickens, but dont try it on your grandmother.I wove two wires in the bottom of her cane chair and gave it a crank.&nbsp;I learned that at 9 years old,&nbsp; she had a tough left hand

I just have the lights that you buy in a regular store for a euro... or a dollar (Yes I'm european, I'm from the Netherlands(and we have L.E.D. traffic lights too :D)) you get three and there are three L.E.D.s in one light.
i found hundreds in only one matsushita photocopier google it.
I was wondering where the big array of white LEDs (first picture) came from.
i&rsquo;ve seen arrays like that in cheap flashlights
My best market to find leds and other electronics for free are the recycling boxes in most of the stores here in Greece. You can take any electronic from vacuum to a hifi and take appart all the electronics. I visit them twice a week and i got many interesting things
And I have one of these that won't work right!!!! Thanks! It has something to do with the connection to the switch.
Kewl! I have LOTS of old phones! :D
Unfortunately, most of the LEDs you have demonstrated are only meant to be seen, not illuminate something else, and the number yielded for the effort expended probably does not justify the activity, unless you are also recovering significant numbers of other components that you can re-use.
Those are actually halogens.
The charging ciruit used a neon to show when it was ready to fire, but newer circuits use a red LED.
good 'ible, but unless its the end of the LED contest and you have to have the LEDs that day, it's allot easier to just get them off eBay for really cheap. I just got a pack of 1000 white that I bought for only $15, and they ARE good quality, unlike popular belief! :)
