I released some magic smoke today. I was setting up some Ross switches for non derailing with DZ machines and I fried one of the two button controllers. Took it apart and a trace was burned, but also one of the push buttons no longer worked. Fortunately not very costly.
This put out a very thick smoke and I am pretty good at creating it. I'm thinking of installing a rack over my electrical bench with upside down vials and corks ready to capture the smoke. I bet it would bring a ton on eBay. Think of the value add if I fried a Hogwarts engine.
