hey sci i've a question
so i was watching the third matrix just for the hell of it, and i noticed the turrets their central tower. They caught my attention as they had to points of rotation and were shooting the fuck out of the sentinels. I was curious though, i've never seen a picture of a turret like machine that worked the same way.

I thought about it briefly and came to the conclusion that building a scaled down model might be do-able (for someone with my knowledge and resources). The mechanics seem fairly straightforward, however the electronics involved are WAY over my head.

I was thinking of controlling this via USB, so i was wondering if anyone here had any experience with designing shit that's controlled through a USB connection or how one might wire the motors. Any information or leads to resources of information would be greatly appreciated
Thanks

>>964662
yeah i suppose so. that's a turret all right. I'm going for aesthetics here though. not so much actually shooting anything... so i'm aiming to make something very similar to the design in the picture.
the turrets on naval ships are the closest thing's i've seen to this. and they are very interesting, however, they're extremely large.. and don't look very badass. or, at least as badass as the one in the picture there
