well, im not an electronics major, just an electrical engineer.
here is a 4.5 battery. chip wise, check somthing like this out(first one). I'm pretty sure a ground connection is necessary, but i could be wrong. (transmit proticall)
Thanks for the pdf, i couldnt find anything that nice. The one i found conflicts, so I will try this one out tomorow. Let me know if you need any help with that.
