(...) Wow! Way cool. Spotlighted. So are you going to productise these? (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) As Lar said, very cool! Question: Is each light individually controlled, or is each red/green pair controlled together? (I don't know much about DCC - yet!) And where is the yellow light? <grin> JohnG, GMLTC - thinking our club needs to (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) Mark, these builds are, as always, awsome. One question, do the 4 outputs on the quad conroller have a common return path on the controler? I.E. 5 output wires or 8? Also, are the 4 outputs indepentantly conrolled or only 1 at a time? I've yet (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) Thanks, Larry! (...) Presently, I don't have any plans to do so. These actually took more time to create than I'd care to admit! However, much of the time was spent working out the construction details for the prototype. I want to build (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) Thank you, John! (...) Each of the lights is independently controllable. You can even instruct the DCC controller to blink the lights in various patterns. I'll be working on software to provide an interlock so that only the red or green can be (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) Thanks, Mat! (...) There are 5 wires for the lights. The common is positive voltage with respect to the 4 output wires. Each light is independently controllable, you could even blink them to simulate certain real world signal conditions. (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

Hi everybody, (...) Correct. 7860 is the set number. A quick Google search turned up mostly auctions and sales pages, no useful description of this set, so here go some basics for the interested ... Both the red and green light are controlled (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Could you use a "bi-color" LED this way? Polarity one way, light is red. Polarity the other way, light is green. Polarity alternating, yellow! (Ok, that last part is probably a pipe-dream... <grin>) Can DCC output a voltage with either (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) I was thinking of something similar. Using 2 outputs you could control a 3 lead Bicolor LED. Or with a small NAND gate as well, you could use the 2 lead style LED that you mention. If you don't mind the LED always being on it only takes one (...) (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Yes, otherwise you could only run a DCC loco in one direction. ROSCO (20 years ago, 21-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) Hi Horst, that's a great picture. Yeah, that's what I've been striving for, a layout of roughly that complexity and automation, but without nearly as many wires. The remote controllers (along the bottom of the picture) being replaced by the (...) (20 years ago, 22-Oct-04, to lugnet.trains, lugnet.parts.mod, FTX)

(...) You can get 3 colour LEDs that are designed to work that way. Not sure, but think they are orange as 3rd colour though. (...) Yes it can, motor outputs are reversing. So, using any stationary decoder that can power reversing switch machines (...) (20 years ago, 22-Oct-04, to lugnet.trains, lugnet.parts.mod)

(...) I think with a red/green bi-colour LED you can get any colour between the two by varying the mark/space ratio of the alternating waveform. A DCC controller varies the mark/space ratio of a square wave in order to drive the motor at different (...) (20 years ago, 28-Oct-04, to lugnet.trains, lugnet.parts.mod)
