Hey, I have been wanting to do a hack to backlight my lobmard keyboard. I was thinking I should use some light string, but I dont know how I should power it. I was thinking maybe of the usb or the inverter board of the lcd to make it work with the backlight on hte screen as well. I have no idea how to do this though. Any modders have tips?

There is a hack somewhere on macmod.com. It's for a tiBook I think but it should work for yours too. I think he used Fiber Optic.

Fiber optics with small nicks in the run works pretty well, having everything lead back to a single LED. There was an iBook one done this way that did, as you mention, tie into the backlight inverter, which had the bonus of dimming it (though tied to the screen...).

There was an iBook one done this way that did, as you mention, tie into the backlight inverter, which had the bonus of dimming it (though tied to the screen...). Something's not quite right here. A backlight inverter produces hundreds of volts (the better part of a kV, in fact) at low current. LEDs operate with a couple of volts at 10s of mA, say. If the iBook project was tied to the B/L inverter, the keyboard light was most likely CCFL-based as well (unless its particular inverter module has additional, low-voltage outputs that are not found in conventional modules).
