Yeah it happens
have to remember though, conversations do run along.
In regards to resistors for a smoke unit.
while resistor's are handy,
I mentioned before ,about using a full wave bridge rectifier to run a fan the of an ESC.
I mentioned getting that part from an old hair dryer ,
when your done scrapping that hair dryer ,
you will be left with a bunch of bits , a switch,a thermal switch, motor and ducted fan, and the heating element wire for the hair dryer. nichrome wire..
A guy can experiment with what length of wire will produce the smoke he wants.
then its just a matter of measuring the resistance of that length of wire ,to make replacements.
simple..all a guy needs is an old hair dryer to begin bodging a smoke unit
http://en.wikipedia.org/wiki/Nichromegrain of wheat bulbs are incandescent .there life span and current requirements
like any incandescent bulb ,everytime you turn it on you risk blowing it ,
Leds are solid-state and low current requirements ,can last 20years, and more than 500,000 power on cycles, can run upto 750,000hrs.
a guy could easily get this out of and incandescent bulb. Just don't cycle it of or on.
I have a Compact flouresent (different beast I know)bulb on my back porch ,13watt ,it been there 6years , I don't turn it of , I vee replaced every other bulb from that same package ,except for that one, no cycles no wear and tear .
