While I know this topic has been widely discussed, I thought I'd throw my information out there for anyone who is interested. No I haven't made anything synchronized to the chuffing of a steam engine. All I have done is make some basic circuit diagrams and a quick video to help walk people through the process to make fan driven smoke work with a Blunami decoder. The method I use consists of a solid state relay and an assortment of mini dc/dc buck converters depending on the specific smoke unit being used. Feel free to check out the diagrams attached and in the linked google drive folder. I have a short video going over the concepts and the two main types of smoke units. Hopefully someone finds this helpful
