So I've started experimenting and getting some bits together.
I've purchased a small project box off eBay which will act as the oil reservoir ( the oil is going to be standard baby oil from boots)
A small computer fan that runs off 3-6 v dc
Some heating element wire, from a friend that builds E cigarettes
A small length of fire rope (the fibreglass style rope found on fireplace door seals) ( this will be the wick)
I still need to purchase some plastic pipe and right angle pieces to make the "chimney"
My next question is this
My power supply is a 6v dc 4ah lead acid battery (graupner)
I have been experimenting with the heating element, I need it to create enough heat to make smoke, but also balance it so that there is not a massive current drain therefore making the running time an acceptable level.
I still need to establish how I will connect the supplies for both the fan and the element, some people suggest connecting it to the output on the ESC , I like the idea of this as it will give a realistic amount of smoke when the motor is running, or I can wire it in directly having it run constantly.
With regards to the resistance of the heating element, essentially this is just modified by the amount of coils I put in the wire (wrapping around a small screwdriver) at the moment.
At the moment of testing I have 2 ohms resistance, but this has a huge current draw, does anyone know the average resistance of a 6v smoke generator coil? I've been looking at Seuth model train ones and they suggest around 15-20 ohms
