My regular supplier sells an eGo adapter for charging your cell phone, which struck me as a brilliant idea. But why aren't there more products like that? How about a 510 threaded electric razor or nose hair trimmer? Maybe a little LED flashlight attachment? Weren't the first vape mods made from flashlights? Shouldn't be so hard to do that in reverse, right? I think vape mods and batteries could become the electronic Swiss Army Knife of the future. Maybe someday even a laser scalpel like they used in 'Alien' to cut the face-hugger, hehe.

Any ideas from the ECF community? I encourage fantasy and funny ideas as well as practical ones. And please, remember to stay within forum guidelines so we don't get deleted for having a thousand suggestions for sex toys...

How about one of those hand-held DC fans. Putting a 510 thread on there is simple enough, but I wonder if they can take the brunt of harsh chinese mod PWM.. Another reason to buy a provari?

Interestingly, the fan and the LED flashlight would work very well with "harsh Chinese PWM", and work very badly with a nice clean Provari voltage.

Electric motor speed control is generally PWM. The voltage spikes help defeat stiction I think. It's how model train-sets work (or used to until they got digital control, still might internally.) LEDs need constant current, which is generally provided by just a simple resistor. That means they have to be designed for a fixed voltage. When you see an LED being dimmed, 99.999 times out of a hundred, it's being fed PWM. Persistance of vision means you see a continuous light, and you see the average brightness.
