Could we get a few more pictures of it? I'd love to try and make something like that.

6 amps current draw!? That'll suck my batteries dry in minutes! D: All I have are the 9.6v 700mAh RC car batteries. I could stick three in parallel, but still. How do we limit current flow on those?

Sorry for the late reply, but I think what you're looking for is a current-limiting diode.

You could have a thermister in a wheatstone bridge to control the temperature with the peltier. It'd limit current and should theoretically keep it at a constant temperature, as well.

Alternatively, could do do it as a microprocessor project and have a thermocouple to tell the micro what the temperature is and have the Peltiers active only as needed, and possibly through PWM.

Another Altoids tin project, gentlemen. I give you my handmade e-cigarette case. All designed and hand-sewn by me.

It should hold two batteries and up to six cartridges, or maybe some mouthpieces. Fits conveniently in my pocket and keeps everything protected and free of pocket lint.

the e-cig I have came with a case. it acts as a portable charger and enough to hold 2 cartridges. rarely use the thing though, I enjoy regular cigs better :wink:

I find these are a good way to simulate the relaxing effect of real ones without all the downsides.

Took 3 hours. Don't judge.
