So I have a couple of nice steam engines now (USAT Hudson, AML K4) and really wanting to add a nice smoke unit to them and really get a chuffing effect. This far I have been less then enthused about what is available. I ended up seeing video on the KM1 smoke unit from Germany and it looks impressive but I cannot find out much information on it. I am wondering if anyone on here has gotten one? I am trying to determine is it a self contained unit that is driven by magnets put on a shaft? Can it be driven by a chuff sensor? Does it require triggering from some proprietary board from KM1? I am trying to determine if this might be a good solution for what I am looking for. The German manufacturer can be found here:

Video of it in action can be found here:
