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....

Ebay has 100 white 5mm LEDs for £1.15, 100 assorted LEDs for £1.75 (yes, all the way from China).

Still, right from my childhood I learned a lot from taking things apart.

Sometimes I even got them back together again.

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?
You get a long metal rod with rubber insulation on one end.
(make one by wrapping whole bunch of insulation tape on one end of it)
Flip the TV and remove the case.(wear rubber gloves if you don't want to be like me)
Now it's time to use that metal rod,just poke around until you hear loud bang.
Don't worry,it's now discharged.
(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)
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
Discharge the metal end to ground just incase it's charged
You need 2 screwdrivers with insulated handles make sure you DO NOT touch the blades place 1st  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   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
REMEMBER THIS IS A CAPACITOR AND WILL RECHARGE UNTILL FLAT
Hope this helps you Rog
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

itll be cheaper to get some leds from the store than to break all this sh*t up..
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" B/W TV and pull the capacitor and shock my older brother when he was sleeping after a long day of sibling abuse.

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....
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
You are the Payback Master! :D

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.

That's less than 8 cents each!

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

This is a monitor ,not a computer.However the big box thinggy also have at least 2 LEDs!

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?
chaydgb Lhtrf3 years ago
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

Better still, find a less dangerous source of components!
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. I learned that at 9 years old,  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 was wondering where the big array of white LEDs (first picture) came from.
i’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.

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.
