El Reg reports
A forensics report has reported the first known death from the use of electronic cigarettes after a Florida man was killed when his device exploded and drove itself into his cranium.
Tallmadge D'Elia was vaping at home on May 5 when the vaping device, manufactured by Philippines-based Smok-E Mountain, exploded. An investigation by the Pinellas-Pasco medical examiner's office found the explosion fired two pieces of the vaping device into his head, causing death by "projectile wound of head".
D'Elia also suffered burns to 80 per cent of his body, the ABC News reports,[1] after the explosion caused a fire in his house. Firefighters found his lifeless body when they broke in to tackle the blaze.
A representative from Smok-E Mountain said that the problem was most likely a battery issue, or a problem with the atomizer D'Elia had in his mouth. It said the company had had problems with people cloning their devices and using bad batteries.
While D'Elia's death is a first, injuries from electronic cigarettes are surprisingly common. A report last year by the US Federal Emergency Management Agency found that between January 2009 and December 31, 2016 there were 195 incidents where vape pens overheated or exploded, leading to 133 acute injuries to users, 38 or which were described as "severe".

Best Practices recommend that anything remotely electrical that you put into any orifice such as the mouth should always be connected to the mains for power.
As suggested by the anon, an inline resister is better than a transformer power supply because it is much simpler and therefore more reliable.
As we know, all diodes can be light emitting -- at least once.
But further research has indicated that there are also light emitting resistors! Such resistors should be part of the device you put into your mouth.
Further investigations into light emitting resistors were interrupted. The researchers are anxious to do further experiments. The principal investigator's wife insisted that further research on light emitting resistors must be moved to the garage.
The lower I set my standards the more accomplishments I have.
