Sorta makes sense, I guess. Dave Setser RV-7 Wings Arlington, MA ________________________________ Message 2 _____________________________________ Time: 07:37:45 AM PST US From: "Robert L.

From: Greg Campbell --> AeroElectric-List message posted by: Greg Campbell I have a little alarm control panel with a red LED that indicates when the system is "Active". The problem is I need to "see" that information in places other than where the built in LED is. I'm hoping someone could help me build a circuit that would let me add additional LED status indicators in 3 or 4 locations. I figure there are at least two ways to approach the problem: 1) keep my wires "outside" the alarm box by putting a photo-transistor or something over the master "status LED" and have it drive the other LED's to follow suit. Clunky - but it avoids voiding their warranty or intruding on their circuitry. 2) go ahead and pop open their box and directly tap into the circuit that feeds their LED, as well as swipe some of the 12vdc to power my "LED repeaters". I'm thinking this could also be done with a transistor, or worst case, with a transistor and small Bosch relay. I suspect that their status LED lights up with a forward voltage around a volt at 20 or 30mA, so I can't just tap a 5v or 12v relay coil into it. I might be able to figure out how to do this on my own, but I'm betting that there is some expert out there that will find this a piece of cake. Any takers out there?

You may be able to use that signal to drive a relay directly. LED's usually run about 2V forward voltage, so you can find out how much current the LED is pulling by dividing the voltage driving that resistor minus 2 by the resistance. It may not be as high as 30 mA. You can get reed relays that will switch .5 A and need about 10 mA at 5 or 12 V to operate for a couple of bucks. Even better might be a solid state relay such as the Claire CP1030N that will turn on with a current of 2 mA. You'll need your own series resistor to drive it. Bob W.

From: --> AeroElectric-List message posted by: Hello Greg Perhaps you could drive multiple fiber optic indicators with 1 LED? Perhaps you could talk to an engineer and see how many mAs their circuit will drive, and use a fair powerful LED?? My take is you are not having as much fun as you can if you still have a valid warrenty!

It works but too dim to be useful. Might work with a lens at the LED end but I didn't have a lens. I just ran the wires out and moved the LED for my situation.

Another (better?) way of stating my question would have been: Bob, when writing ...crimp.pdf... did you base your crimp die selection from RG-400... *Sigh* I never could get anything but mediocre B's in English.
