I have been working on a simple power regulator system to work with 9V battery's to make it eraser for to power 6V portable device's finely did it today and work's with all kind of boards and it also stabilize's the power with a simple plug-in design for input and output of the power. ANY GOOD IDEA's To make-it anymore simple. because I had to use a 8pin IC "741CN" to control the volt's and amp's.
