Though I'm not sure if/how it will work. I grabbed the only op amp that radioshack had. 741 op amp. I'm not sure if this is interchangeable with yours. Before I hook up to battery power, I wonder if you could explain? Also, is it possible to use a 9v batter instead. Why or why not? and how would i go about grabbing usb power? Obviosly I'm a little green with electronics. Thanks so much. this project is very cool and I'm glad you shared it. E Hey I just soldered most of the circuit together (the simple one).
