This was what finally killed the 'Skybook' - an attempt to build a backlit keyboard. The picture's kinda bad, but the iBook is actually booting up there, with the two LED's on that board lighting up, powered by the LCD power from the iBook.
Later on, when my friend would solder it all in, though, after all the time spent setting up the fiberoptic wires and the LED's... he would put in the wrong resistor. Frying the LED's and the logic board within seconds.
Man. I never wanna hear anyone say "Is it supposed to be smoking like that?" about any of my computers.
Oh, and you can see what it looked like before its demise in the second picture, bottom left. Gotta love those G3 iBooks.
