    Hi, first off I have not dabbled in any sort of electronics, so I'm a total noob when it comes to this stuff, but willing to have a go at it.

    I want to light up my Judge Dredd Lawgiver blaster the same as in this clip (jump to 3:18) so basically when you activate the switch, 5 LEDs on the left and right of the blaster, light up in sequential order and stay on until the switch is turned off.

    Also there are two LEDs on the actual activation switch (a blue and red) that would need to light up at the same time, seen here on the left

    Any advice on this would be great as I wouldnt know where to start :confused:

    How many batteries can you hide in that thing?

    Thanks, will look that up :) It's quite roomy. I'd say possibly 4 AAA maximum, though could I get away with using watch batterys?
