I'm not sure how this will be received here, but has anyone ever heard of an MFLB? It's a simple, battery powered herb vaporizer, and I'm trying to make a DIY version of it for myself. A layout of the basic circuit can be found attached to this post. Basically, you're shorting out a battery to generate heat across the "trench" which is comprised of steel mesh. The rest of the circuit is made of bare copper wire.
What I'm trying to figure out is what size steel mesh I should use to get to the desired temperature (170 C) in about 35 seconds.
So far, I've used P=(I^2)(R) and deltaQ = cm(deltaT) to get this equation:
T(t) = (V^2/Rcm)(t)
Ideally, this circuit would create little heat in the copper wire and in the battery (obviously) and most would be generated in the steel mesh region. So, my question is, what combination of resistances would create this type of situation? As I understand it, the resistance in the copper wire will depend on the length and diameter. But how do I go about finding the resistance of a square steel mesh?
