Well, I've been looking at Audio amps... The LM383 would have been perfect but it's obsolete. There is a replacement for it though and I found a few others that I like. Almost finished with my armor so I'll start working on the PIC circuit as soon as I get finished with that... And yes, I know Star Wars isn't real

BUT neither were microwaves and color TV not so long ago... he he

Have a great evening!
