Hi Ben,
Love your show. I am an avid "vaper" (user of electronic cigarettes), how I can understand you nor your associates can advocate the usage of electronic cigarettes, I however can tell you that they saved my life. The average modern electronic cigarette uses a dc to dc converter to allow 3.7 volt LIPO batteries to heat up a coil of Kanthal or Nichrome to vaporize "e-liquid". Most now days are variable wattage, voltage, or even temperature. One of the most modern chipsets that regulate the power is the DNA40 by Evolv. My question/build suggestion is this....Build an arduino based system that has an output of up to 100 watts , 20 amps , 8 volts , etc...I know the average arduino chip cant handle the average amperage draw of modern e-cig atomizers. How can we use the arduino platform to control something like a MOSFET to have a variable power output? If the arduino just cant handle it, how can one use something like a MOSFET, and make it have a variable power output?
My love for electronic cigarettes has saved my life as well as many others. The reason I am suggesting this build is that a lot of us "hobbists" build our own E-cigs out of some batteries, a switch, and a mosfet. I know there has to be a better, safer, faster, more efficient way. I would be more than happy to advise and or correspond during the build.
Your avid vaper,
Tyler
