The project: I have a ccfl backlight from a portable dvd player and i want to use it for a keyboard light. I am tapping into my power supply in my computer, a free 12v connector. The Problem: I cannot get the voltage to drop even with the resistors in line i still get 12v. The resistors are good, I tested it with a multi-meter. Here is what ive done so far from the 12v connector there is a 330 ohm resistor which should give me near the 3.3v. I need for the digital part of the circuit, and on the other 12v line I have 100 ohm resistor to give me about 9v. The 9v is going into a transformer to provide the high voltage for the ccfl. Anyone know why im not getting a voltage drop? are my calculations wrong? Thanks for the help.
