I made a board with 10 LED and a cover of black styrene with small holes, to put the fiber inside.

Here you can see the fiber.

Yeaah!!!
And for approximated two seconds they were REALLY bright!

I've found a good idea while building my 1/350 PL-Refit. First, i soldered several SMD-LEDs an resistors on a board and mount them into the nascell. http://www.doomgiver.de/downloads/bilder/modelle/enterprise/Enterprise_025.jpg http://www.doomgiver.de/downloads/bilder/modelle/enterprise/Enterprise_0...

Another very interesting project is the Arduino ( http://arduino.cc/en/ ). Especially for people without experience in programming PIC/Atmel, this could be very interesting. Controlling servos, motors, LEDs (with PWM you can easy simulate the Photon-Torpedo-Effect for Star Trek-Models or engine-flic...

You have forget a very important part for MOSFETS: The Pull-Down-Resistor between Gate and Ground. 100k-1MOhm Resistor is recommendet.

i don't know how you can calculate resistor values without knowing the LED's forward working voltage and their forward working current. You don't want to guess on these since you will either under drive the LED or overdrive them. He want's full brightness so that means getting the exact requirement...

Here is your list:

10x: 2x LED(white) + 150Ohm Resistor
1x: 3x LED(red) + 180Ohm Resistor
1x: 2x LED(blue) + 150Ohm Resistor
1x: 1x LED(blue) + 390Ohm Resistor

Total current is about 250-260mA.
