This mod uses a diode in series with the atty to provide about 4.2V. My first mod ran at a straight 5V with a 901 and runs a little hot. Since I like the BE112 pen style best, I decided to make one to run at 4.2V (measured under load).
Once I got it 'built' I had trouble getting the switch mounted, so it stayed outside, but is solid enough.
It's now my favorite vaporizer.
