Alright, here's my problem... I want to build a "Rumble Chair" for my N64. That would have motors under the bottom, on the back, ect. of the chair. And as for the circuitry, well, that's what I'm here for. Now, for one, I need schematics for the rumble pack. And I could take apart a rumble pack and have two wires going from it to my chair. However, I don't want to do that because the pack will be to bulky, the two wires would have to come from somewhere, so I have to drill a hole in the pack which will make if look sloppy, and, I don't want to spend any excess money on the pack. So, this is what I want to do. I want ribbon cable coming from the port on the bottom of the controller, and the circuitry can be stored in a box mounted under the chair. And what would be nice is if I could have a port mounted... somewhere on the chair, where I could insert a memory pack. (I can get a port from one of my tons of busted N64 controllers.) Now, my last problem is: The rumble pack normally is powered from the system. It can do this, because the pack only has on motor to power. But if I'm creating a chair the will require multiple motors throughout it, I need more power. What's that? I could use a relay? Sorry, no go. Relays are an on, off thing. The pack's rumble can vary due to how intense the rumbling is on the game. So relays are out. Can someone please help me with this mess of junk? :?
