Okay....
So I've been wandering around the game for like HOURS now and I just need a quick couple of spoilers about where these darn gadgets are. The ones I need are the laser pointer, electric eye, and loudspeaker. I've been EVERYWHERE in Marten's Bluff and still can't find it and Mt. Gigas is a zoo if you don't know where you're going. If someone could help I'd appreciate it. Thanks!

These two things were *meant* to be in the game but the developers left them out in the final release.

The laser pointer is an item hidden in Sadok's lab in LMB around to the left behind the table when you walk in. You actually have to walk in close to it (with either a ranger or search mode active) to discover it. The other two, as was said, were left out of the game.
