Please excuse my newbie status in the world of electronics but I really need some help here. I am making a costume that has a bladder of sorts that sits on my back. I would like the bladder material to move up and down to look like I am breathing. I didn’t want to use air and though servos just might do the trick. I want to buy a circuit board, battery and servos from the pololu site but I’m not sure what to get. Any help would be appreciated sooooo much.
The space i am working with is about 4x6 inches (depth 3 inches or so) and the servos need to push up some vinyl fabric at my neck. I’m hoping you can make a suggestions of items that might work. So basically my concerns are that the servos are strong enough to push up the fabric and lower it, the servos and circuit board fit in the space i listed above, and there is a button or remote to turn the servos on ( and info on the best battery pack to use). Any thoughts? I have just over 30 days to complete this so I’m working hard to get everything in order.
