510 accessories

[67exec]

In complete and utter boredom with a need to build something from stuff I have lying around.  I'm trying to build some things that would make my day to day life more fun, and would like to use a dna instead of a mech. Is there any way to make a dna device (60, 75c, or 250) output a specific voltage instead of wattage, and it looking for resistance? I'm looking for <5v and maybe 2a at most. The 15-20 sec time limit is useable. You can already get a 510 flashlight. So why not make other things, mostly novelty, but I know of several things I could make that would be handy in the automotive business.

 

any help would be appreciated

just do the math perhaps? 

4 e.g. u got a 2.5ohm bulb that works on 2A, so the voltage would be 5v and boom u got the watts. 10W.

But some things have changing resistance like a motor. Load can change resistance.
