Intro: The Mini Vape (Pictures)
Just some pictures to give an idea of how this is assembled and the inner circuitry. I clamped and soldered solid copper Romex* wire at 12-14 awg to a 325M stainless steel wire mesh. Solder the copper to the S.S. with flux and used silver-based solder. The cover is clear acrylic, the cover's clamp is brass rod, and the lock is a single shotgun shell metal ball - a tiny ball bearing will also work. I wrote a program of the circuitry functions and Newton's thermal law of convection to optimize the screen dimensions for the longest battery life. The screen dimensions allow the battery to heat the screen to about 390 - 400 F steady state and last up to 13.5 minutes. Experiment with screen sizes on your own or do as I did and run the circuit theory calculations.
