I think he wants to lay down, aim, and hold breath in one move.
lets see, this would all be better served through accurate timing with a pic, but being the mechanical minded man I am, leads me back to the SPDT switches we were talking to jasmine about. this is a swithc that is pressed once and closes two circuts at once. but they are hard to find and to find one small enough to go where I am thinking would probably be imposible.
just brainstorming and typing...the b activation is just closing the loop between top and bottom of the pad..is this low?? and the hold breath, it is just a normally open tact switch mounted under the stick. so could these be wired together to a normally open 3mm tact switch. place the tact switch under the left trigger knuckle...so when the left trigger is fully pressed and held, you would lay down, aim, and hold breath at the same time... there may be a timing issue in the hold breath... I need to do some more research, and play with the controller a bit. chad what do you think? oh yea for the record we are now 1-1 LOL
