Re: NON SMOKING EXHAUST WITH AIR INJECTION

Hi JB, I have caught up now and by reading through the posts to see your journey. I have been on a similar journey - I thought I would share some of my learnings. The electronics in the may well drive a display, buttons +/- and a display interface etc but the basic electronics for the power to the coil are very simple. The power is "pulsed" to the coil using Pulse Width Modulation - basically in each cycle how much time the power is ON or OFF - very similiar to a domestic dimmer switch. By varying the pulse on/off period (Duty Cycle) I can adjust the power being supplied to the coil The coils do not have a voltage limit (I run my standard coils from a 12v SLA) - they do have power (watts) limit where watts =volts x amps. I am not sure on the spec of you voltage regulator - it may be constant current - so when you drop the voltage to 2.x volts your are essentially dropping the overall watts in the circuit. The resistance of most coils is single or sub ohm so are almost a short circuit - no surprise your voltage regulator gets very hot/spits it's fury I create my pulsed power to the coil using a MOSFET I also have a temperature sensor in place to auto shut things down if needed and will be a able to remotely monitor each of the 9 smoke devices remotely Hope this adds to the subject _._
