I would like to share with all of here with interesting mod that i've done,suitable for bling-bling modders.Im using lpt port (parallel port)for this mod.Since there are no such topic start in here,so here are the procedure to make this project.
WARNING: PC parallel port can be damaged quite easily if you make mistakes in the circuits you connect to it. If the parallel port is integrated to the motherboard (like in many new computers) repairing damaged parallel port may be expensive (in many cases it it is cheaper to replace the whole motherborard than repair that port)
** tested on windows XP & vista & Win 7 and it work like a charm**
PC parallel port is 25 pin D-shaped female connector in the back of the computer. It is normally used for connecting computer to printer, but many other types of hardware for that port is available today.
Items you need : 8x LED (any color)
8X resistor ( i use 1k ohm)
extra wires
Printer cable
Masking tape (heat shrink is more better)
Additional note : You can do more better by using IC board.Mine is for testing only
First of all,here are simple diagram,hope this help
You can make up to 8 LED,picture above is example of wiring diagram only
1)1)Ok,lets begin the first step.Take the printer cable and cut the cable to female side using cutter.Then you should have 1 long cable with male connector in the end.After that,cut out the cable shield at the part you cut the female side.You should see a bunch wires and each got colors.So,to make sure what wires you should use,refer back to the male connector.You should see there are codes for each pin (look closely) at this male connector.

After cut
2)The pin in male connectors should have a number like this 1-13 and 14-25.So the male connector got 25 pins. The wires you should are number 2-7.So,check the connector back and look the pins 2,3,4,5,6,7 and look what color for each numbers.Usually number 2 pin should red color wire while number 3 pin should orange.For 4-7,just check it out by urself.Be careful while choosing the wires because there are wires with same colors.To differentiate between this to wires,there are some black or white lining.

3)Take the connectors and put the LED just like the picture above.The LED should be place in positive first which means the positive side is a left end of connector.
4)Take the first wire (number 2 pin wire,is a red color one),strip it a little.Then take the resistor (any side) and twist the wire to the resistor and solder it.Then place the resistor in connector and tight the screw.
5)Now the positive side is settle already,now the negative side turn.The number 2 row (from left) should be negative side.The -ve side of LED should already insert in connector. Take extra wire and cut it around 1 inch-1.5 inch.Strip it and it should place opposite of -ve LED leg (please refer to the picture).
Extra wire to connect each -ve
6)Alright, +ve and -ve side for first LED is done.Now do it for second LED. Same procedure,just find number 3 pin and check the wire (look out the colors).Take the number 3 wire and strip it to twist with capacitor,then solder.Insert the resistor to the connector and tight the screw.Take the LED and place it just like number 3-4 procedure.

.But for sure,no windows media player plugin for this mod.
. LED cannot tahan la if u connect at 5V,but put resistor should be okay
