hehehe..
nice modding..
wiLL trY later..
hopefuLLy no KABOOOOOMMMM...
heheh...

Wow...TS you are something lor...

Ha Ha Ha...wonder how you have an crazy idea???

BTW...its awesome...

best tread can make my pc look like disco edi ehehehehe

Metkumods

Bro...cool...

very cool and helpful guide haha
i'm happy with mine after learning from those guides =P

nice mod.
already know how to mod no need to spend give ppl help mod haha~

still got some question on that...
1.how to differentiate which pin on the led is positive and negative?and which pin need to plug to ground and 5v/12v?(i rmb form3 KH got learn but i 4get d...XD
2.the resistor nid to plug at positive side or negative?
3.can add a switch for that?

^^i wan start learn led mod dy...

google is very helpful to learn about it ler.. type LED or light emitting diode then a whole bunch of info would appear..in wikipedia mostly..
also with resistors..

see carefully within the LED..
there's a flag shape..that's the negative..the other is positive.
or
both of the LED legs are different length..one is shorter than the other..the shorter one is negative aka cathode (english) aka katod (bm) while the longer one is positive aka anode (english) aka anod (bm).. usually people differentiate it by looking at the legs as it is much easier than remembering the flag.. katod (bm) in a way also means shorty lol..

resistors has no positive nor negative o_O
either way is fine...read about resistors at google/wikipedia if u're unsure lur...

switches can be fitted either at the negative or positive..up to u..it's usually at the positive after the source or before all the resistors or LED or whatever..

if u're not using resistors...better make sure the source is around 3volts, don put more than that..if not, say bye bye to ur LEDs...



well, do some calculations using those resistance, voltage, amperes, bla bla bla.. I equals V over R that equation..lol..
also take note whether u wanna put it in series or parallel..
the voltage is shared when put in series whereas all the voltage is equal when put in parallel.
haha..buy more incase some got burnt or whatever~~


GoodLuck =P

Some additional Info, the color of the LED will also determine the working voltage of the LED. Different color uses different die. For lower wavelength LED such as UV, Blue and Green(Super bright) and also white LED, the forward voltage will be around 3.5-4v. As for longer wavelength, such as green to red, the working LED will be around 1.8-2.5v. As LED is current driven, so it should be powered by a current driver, but as a driver is more complex, so we cap the working voltage accordingly using a resistor. So just do the calculation and use the approriate resistor.

Added on April 4, 2009, 4:53 pmAs for the resistor recommendation, if the source is 5v, the recommended resistor value for blue LEDs should be 75-100ohms, and for amber, red LEDs, it should be around 150-200ohms, correct me if i'm wrong. I'm assuming the forward current for the LED is 20mA.

oh dang, haha..i burnt 5 blue LEDs when i set the voltage to 4.5v TT_TT
didn't have any resistors then..

anyway. thanx for the ADD!

i giv up the DIY d,very hard to solde on the both pin. i think coz it's chrome surface.

i advise... find a good sholdering pen and solder...

last i very easy to solder... but until i finishe the solder , i cant continue... the newly bought solder is so bad it cant melt or stick.

is solder problem ar ......
the timah can lekat on the pin surface,i just don 1 molex oni.
the rest,i giv up d. i purposely mod my 5mm superbright led,

i got something suprise coming out... i sholder somthing for 3 hours non stop...

later/tomorrow open new topis on that

wow,waitiing ur surprise
