Not that I vape, but I think temperature would be much more 'interesting'
than voltage.

Paul,
The code already measures the battery voltage, so it wouldn't be much work
to display this in a suitable scale factor such as percentage of full
charge. There's plenty of room in the PROM.

I suppose if there is room in memory, you could have it telling time as 
originally intended and also battery status..

Thank you for the suggestion!

That sounds like a good application for my Nixie watch circuit.
It runs on a LiPo cell and has a PIC that drives two tubes. You'd want to
display percentage of battery charge.

2017-10-19 Thread Luka C 
I have been vaping for more than 3 years now. I'm not sure where you've 
found the 2-15ohm information on coils, but for most people that vape, 
including myself, sub-ohm vaping is the way to go these days. This pretty 
much includes coils of around 0.4ohm-0.8ohm. Also it is important to 
mention the difference between the non-regulated (so called "mech" / 
"mechanical") mods and regulated mods. The mechanical ones are pretty much 
like a basic circuit with a 18650 battery and a coil, when you press the 
switch, the circuit closes and the current heats up the coil...these are 
however dangerous as in the event of a short circuit the battery will heat 
up rapidly and might even blow up (this unfortunately happens to 
inexperienced users and brings bad publicity to these life-saving 
devices!). On the other hand, regulated ones both have the protection 
circuit in place (reverse polarity protection, short circuit, overcurrent, 
etc) and allow the user to apply specific wattage or voltage to the coil 
(referred to as VV/VW - Variable Voltage/Wattage), thus influencing the 
vapor production, taste, temperature. There is also a thing called TC 
(temperature control) which allows the user to apply specific temperature 
to the coil, thus allowing tight regulation of flavor and preventing the 
possible emission of formaldehyde by not overheating the e-liquid or 
causing dry burns on the cotton wick in the coil.

All in all, I think you could design a regulated mod with nixies to display 
variable voltage / wattage setting. Of course, keep in mind that these 
devices need to be able to fit in our palm and will be exposed to constant 
movement which is sometimes a challenge for nixies' lifespan :)

Maybe a hookah would be a better size-fit.  Could double as  clock you wear
