Hey Friends,
I'm looking to build an incredibly thin heating element with a few drops of mineral oil on top that get hot enough to produce smoke. It's a special effects prop for a play, and a little bit of fog/smoke needs to come out of a very thin object.
My initial thoughts were a bunch of coin cell batteries in parallel up against Nichrome foil to produce a heating element, and then just a small amount of mineral oil on the surface. Build in a switch, the thing gets really hot, the oil reaches it's smoke-point, and then gets switched off.
I'm looking at coin cell batteries like this Sparkfun item:

Does anyone have experience with something this? Do you know how many batteries I'd need to get the heating pad hot enough? I'm pretty sure Mineral oil's smoking point is around 200°C.
I would love any help! Thanks so much!
Phil
