LED Thread

[pseudolobster]

This thread devoted to neat things you've done with the laser diode's incoherent cousin, the LED.

Tonight I was bored so I put some 405nm LEDs into my DX piggy and made a sculpture out of some white LEDs and batteries, held together by magnetism and nothing more. The batteries are sitting on top of a large neodymium magnet and the LED's just stick to the batteries

I just made a video of a BL3000 running at 42 watts

oh and sorry for my voice and how it sounds really fast, when i uploaded the video to photobucket i guess it compressed it in certain areas. Lol i sound like a disclaimer guy on a cheapo commercial!!! ;D

Oh and heres one of my arsenals of LEDs and electrical goodies!

That's an awesome LED array, I can only imagine what it'd look like when it's at full power...

Here's a laptop LCD whose backlight had a dead inverter or bulb, so I replaced it with a string of LED's... I was pleasantly surprised when my battery life jumped from 1hr to 3+hrs, though I was mildly annoyed that I could never get rid of the streaking from the LEDs (which is why I bought the super bright flat-top white LEDs in my "sculpture" in my original post.) It was part of a project to create a portable gaming tablet out of an old laptop which eventually died when I rested it on a screwdriver and it let the magic smoke out. :-/

Not content with an ultraviolet piggy, I decided to 405 my spare pocketpal.. I'm starting to really like these "UV" LEDs from DX... They're dirt cheap and give neat florescent effects to otherwise dull objects. I'm going to replace my computer's LEDs with them.

Whoa k-shell , those are some awesome setups you got there But what's with your voice? You sound like you're in a hurry or really buzzed lol ;D Btw, isn't that 42W actually input power? :-/

What I don't like about the DX violet LEDs is that the plastic covering them seems to be a little fluorescent and it lights up blue. :-/ Have you tried the bigger UV LEDs from DX?

 

[nikokapo]

k-shell, THAT ROCKS...and it was @ 42W....imagine what it'd be at 100W!!

i'm putting leds in my locker(about 30)of them

Awesome thread! I'm really into LEDs
Here's some of my stuff:

Some homemade LED-arrays and LED-guy.

Two homemade joule-thief flashlights, even the boost-circuit is homemade. The LED has it's own socket so it can be removed and replaced with another colour.

Homemade RGB lights.

Video of it in action

Santa's LED-lantern. 16 candle-white LEDs.

My LED-matrix. 240 sockets with it's own resistor. Powered by an ATX PSU at 5V.

The LED collection!
Some random ones.

Moars.

Harvested LEDs from all kinds of electronics, with their leads extended. Each one in the picture is unique.

The main collection. All store bought and unique, spanning though the visible spectrum, 385 to 700nm + white, warm-white, pink, multi-colour, etc..

Other harvested and recycled LEDs.

A few of the high-power emitters (it's such a mess right now, I couldn't find them all). Seoul, Luxeon, Osram's Golden Dragon and other brands. + an adjustable LM317-based test driver.

The homemade RGB+V light-system.
This is my largest project made of ~400 LEDs. Everything is made by hand! It used to be red, green, blue and violet lights, but sadly the violet LEDs where very short lived and only lasted for a few weeks :'(. Now it's only RGB outside but inside I've in stalled some better violets. Ones I get some good spare time I'm gonna try to restore the the rest of the violets too.

The kitchen cabinet. RGB+V.

Front side of the house, not all lights are visible from this angle tho.

Three glass bottles with LEDs are sealed and buried in the ground, shooting beams up in the sky and illuminate the flagpole. It looks really nice in fog or falling snow.

The RGB controller, four channels, three have PWM and dims the red, green and blue LEDs for colour mixing. The fourth channel is for the violet LEDs.

Warmwhite LEDs in the stairs, totally 78 LEDs

The end. Sorry for all the pics!

K-shell, that 100Watt LED is the sexiest thing!

WOW man your house is awesome!

 

[k-shell]

Holy Crap

[FireMyLaser]

Thx guys!

The LED-hobby is cheaper than the Laser-hobby. Sssh, don't tell anyone!

 

[jamilm9]

i like it plus 1

 

[FireMyLaser]

Cool, thx m8!

 

[nikokapo]

OH
MY
CHUCK



fire, that's the awesomEST house i've ever seen!!


can't wait 'till i get my own and start hanging scanners all over the place


you did all by yourself? GREAT JOB!!

 

[kernelpanic]

fire,

+1 for you for sure.

Although saying that you're 'really into LEDs' is somewhat of an understatement... ;D

Happy Holidays Everybody!

cheers,
