So I got my buzz today, and decided to go ahead and do some reverse-engineering on it to really see how this thing ticks. Really not that hard to pull apart (though not recommended as it will void the warranty! Dont do it!).
The circuit board is pretty ingenious. Everything is in a nice little package. There are no worries of failure with this many failsafes! Quite the piece of work.
Unfortunately, there is an issue with patents. Upon close inspection, I was confused as there are several of the circuits that just don't make sense in the overall design. So I pulled these odd components off the circuit board and ran then under my stereoscopic microscope.. only to find...
A FLUX CAPACITOR!!
And now we know why the Buzz works as well as it does. Mike is using time travel to transport vapor from the future straight to the mouthpiece! There really is no voltage regulation at all! He brings vapor from the future, mixes it with vapor from the present, and the feeling is that you get better, stronger, flavor!
Sorry to bust your secret wide open like this, but time travel is a dangerous game my friend, and the public needs to know.
