Something like that.
I tested last night wide beam laser (50mW, 16 mm beam width), have to test it with a smoke (that I don't have).
I also ordered a angel eye ring led light (something like 1W) to test that too.
The smoke production and fan combination has got me stumped. Mains operated and most portable ones are slow to start. Those vaping type seems to be fast to start, but very limited on capacity.
I did some search and looks like right amount of smoke would need over 70W, but less than 300W heating and very little of smoke fluid.
Although I can't estimate if vape type few ml smoke fluid reservoir and works would be correct type to start or would winding my own heating coil be the correct way to go.
Those vape thingys has perry much everything ready, but still need work.
Then again DIY heater coil does not sound too complicated (I have done some styrox foam cutting and several controllers), but fast responce means pretty small coils with low resistance and that type buck current mode converters are not too common.
This type falls short:

1: "Smoke ball" on demand: Vape type fast response and smoke is generated while fan blows it out of the "barel"
2: Pre generated volume of smoke in reservoir and purge with a fan out of barel. This prop has a resrservoir that could be filled with smoke in something like 10 sec and then "blasted" out fastest possible with green light.
* I don't know how long smoke stays good and how that purge would affect on it.
* Probably heating coil would be whole lot less critical with current demand and all, because there is longer time available.
I have no idea, I don't use vape and I don't have a smoke machine.
