Default Ye old Saitek KB Mod

Changing the Backlight Colour of a Saitek Eclipse or Gamers Keyboard

Unlike most backlit keyboards that use EL panels to light the keyboard, the Saitek solutions use LEDís and a light panel. This opens the product up to a huge number of different colour options, but yet Saitek still only offers the KB with Blue backlighting(Edit 2006 - Eclipse Special Ed is in RED). But you can change that, if you donít mind voiding the warranty

What youíll need



Saitek Gamers or Eclipse Keyboard
10 or 11surface mount LEDís (10 in KB, 1 in command pad), 0805 or SMA sized
10 or 11 surface mount 0805 resistors (may not be required depending on the colour of LEDís used)
Multimeter capable of measuring resistance, DC volts and performing a diode test (Optional)
Soldering Iron, preferably 45W and under
Precision Tweezers
Solder and flux (do not use flux designed for plumbing use)
Isopropyl Alcohol and small brush (Optional)
Phillips #1 screwdriver
Set of Allen Keys or Hex Keys

For this guide Iíve selected RED Lumex SML-LX23SIC SMA package LEDís which are available from Digikey. These have a Vf of 2.6V and I plan on running them at 20mA so I need resistors that are at least 120ohms.


Procedure

1. Remove the screws and carefully separate the halves, donít forget the 4 on the top.







2. Leave the membranes in place and remove the PCBís boards that run along the front edge of the keyboard. Unplug the wire from the main PCB, making sure to note the polarity!

3. Measure the resistors and make sure they are of the correct value required for the new LEDís. The ones in my Eclipse were 82 ohms, I need 120 ohms. (If the LEDís you are using are from 3.6V to 5V you should be fine and can skip to part 5)

4. Remove the old resistor and place the new resistors. To remove surface mount resistors and diodes I alternately heat each side of the part quickly switching back and forth until the part slides off under minimal pressure.

5. With the diode check feature determine the polarity of the replacement LEDís and the stock LEDís (some keyboards to not have the polarity marked)

6. Remove the stock LEDís and populate the new LEDís. The package or datasheet should indicate the polarity, if not use the diode check. This is a one shot deal, on both KBís Iíve done the LEDís were held down with glue or something and were destroyed in removing them

7. Clean the affected areas with alcohol

8. Carefully return the PCBís and wires to their locations. If you have used a larger LED like I have you will need to do some minor trimming to get the LEDĒs to fit in the correct locations, make sure they line up with the protrusions.



9. Make sure that the membrane is aligned and then snap the top back into place

10. Screw in the 4 bolts on the top side, then flip over the keyboard and inspect the screw holes, make sure the membrane has stayed in place and not blocked any of the holes.

11. Screw in the screws, flip over and enjoy. To be on the safe side you may want to connect it to a USB hub the first time you power it up, otherwise if you did something wrong, you could be dealing with a toasted USB port on your motherboard.

Fixed the IP for the pics.

New pics tonight, I was feeling the need for a colour change in order to be unique again.

Fixed the IP for the pics again, added the Green Eclipse pic. Sadly I didn't have a tripod so it kinda sucks.

Really awesome results, and a great guide as well. Looking forward to doing this as soon as I get some LED's.

However, my Saitek Eclipse is clearly not as bright as when I bought it, and in some parts there is very little lighting at all. My only guess would be that an LED burnt out but I don't see that as being the case.

Updated with Eclipse in white (not sure why I didn't do this before)
