While I've been a longtime lurker, I'm finally attempting to break into the scene, though with very little knowledge of electronics, I've got a couple questions. I've read the trimming guide, but I'm still a bit lost. 1. What would be a good checklist of required items for cutting and building? 2. Is it acceptable to use a PS2 with a broken laser? I know the dd isn't used in the portable itself, but would that indicate any other fried connections that would need replacing? Thanks in advance.
