This is how i modded some cool lighting into my keyboard and generally made it look a whole lot swankier.
First off, this is what i started with, a Thermaltake multimedia keyboard and some Sunbeam EL wire.
So, diving in, i removed every screw from the back cover and put it aside.
I also put the circuit board aside and removed all the little plastic dongles from the keys and put them somewhere safe, trust me you do not want to drop them, they're a pain to find.
Next i popped out the keys from the top half of the housing to allow me access to the recess under the keys, as this is where i wanted to lay my EL wire:
I then drilled a small hole to allow me to pass the EL wire through to the front of the housing.
Having passed the EL wire through to the front, i postioned the EL wire around the key housings and made sure it was all firmly in place, then taped it down to make sure it stayed in position.
Having put the EL wire where i wanted it and taped it down, i pushed all the keys back in their holes, flipped it over and painstakingly put all the little plastic bits back in the keys...this part look the longest.
Finally i put the circuit board in place and screwed the back of the housing back on.
At first when i plugged it in, it didnt work. I nearly cried. Then i realised that id plugged it into the PS2 mouse port....it was dark ok?
Rebooted and it worked first time. My camera doest do night scenes very well, but im sure you'll get the gist.
