Not much to say about. Buy the humidifier, take out the magic stuff, discard the original case if is too big, fit the parts in an appropiate container and enjoy the smoke. If you have a specific question and I know the answer I'll be glad to help. My Bradley is pleased with this setup, i let it run almost every day and no complaints yet

Now it has engine sound too. I picked some schematics from the web, tried them, make some mods and adjustments and ended with a very pleasant diesel sound. If someone is interesed I can post the diagram.

I received the custom sprockets; they fit well but I didn't like the finish and the material so I send them to recycle bin and find another guy to make a new pair.

All the best,
Vamos
