(Not intended to be a Arduino project)
I need this unit to include a analog stick, 5 buttons, it's Bluetooth, and about credit card size, well slightly wider and no more then a inch thick, no larger. If there's advice i can get it will be great and helpful. I actually want to have a 1000+ units made sooner then later. I'll honestly say that all I know at this point in time (besides very few external resources, and that I need to have a custom PCB Layout created) is that I'm using a 360/PS3 style analog stick, 4 buttons, silicon button pad, one more smaller center button, and what I want the case to be and look like. As far as the Bluetooth set up goes I'm lost, I think it needs to be 2.1 or better for compatibility with most smart phones, I know I don't want to use a Bluetooth unit from a PS3 cause I don't want a required root process to be mandatory for use. I'm not even sure yet where to find a open source Bluetooth device, or what will be compatible for my project that will also be cheap and highly available, not including Arduino products. So... If anyone would care to help me understand all the internals I need for making this device happen will be highly appreciated. Even if I anyone knows the best price and where to get parts that need be. I want to start with a prototype, work on software, then a housing. I'm trying to create a clear understanding of what the cost per unit will end up costing in the long run. Thanks!!!
(I may want to add a mini usb port for charging a rechargeable battery, depending if there is something out there that will fit well into the unit, pending the cost, also if the usb port may help if programing the unit is a need. It sucks that I don't even know the answer to that :~) I wish that these type of projects is what I could have grew up learning about!
