I'm not incredibly familar with electrical circuits, and how to create them, but I do have a strong interest in learning and playing around with some of this stuff. Something I would really like to do is, for instance, is built a lighted breakout type box for an RS-232 port on my PC. Something really simple, that just activates a LED when a signal passes through. I would also like to apply this to something similar, like using the same kind of circuitry in a device that activates a LED when a telephone is being used. Is there some generic transitor/LED circuit that I could use to apply to these humble projects? While I surely don't know a lot about circuitry now, I do hope to pursue it in the future. All and any help that I receive will be GREATLY appreciated. Thanks. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= >< Craig Presnell >< mcp@netcom.netcom.com >< =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
