ary steam or diesel engine, or fac- tory whistle are possible sound applications. Power control includes mo-
tors for animation or turntable control and both individual lamp intensity and overall structure lighting brightness. With some help from Wikipe-
dia, the application chart (DCC decoder uses spreadsheet) gives additional detail.
something that works, I started to explore other possible uses to repurpose old decoders. These included, but were not limited to, three general categories: lighting effects, sound effects, and power
control. Examples of lighting effects
include a campfire, a welder, a burning structure, crossing flash- ers, and so forth. Grade crossing bells, a station-
Background Recognizing the value of these applications, the next issue is how to repurpose them practically. We do not want to power them from the track because of their current draw limiting available power for locomotives. Also, a track short interrupts power to these acces- sory (repurposed) decoders. I first tried to program the decoder for the desired output
