What Ross said.
if I can be so bold. I assume we are balancing:
1.) Size - preference seems obvious for 2", larger makes it a lot harder to use with different terrain set ups
2.) ease of getting batteries - AAA are easier, but not by as much as you might think, especially if you buy in bulk from someplace like Adafruit
3.) Consumer cost - Lion/lipo are more expensive, just... hands down
4.) battery life - depends on the size of the Lion/Lipo you are using, but usually AAA's win
5.) waste - Lion/lipo are better, easy to recharge, though they make perfectly serviceable AAA rechargeables, you just have to have a charger, rather than something like a USB. AND it flips a number of the points above (battery life and expense)
Personally, I think you are better off with a lipo and some kind of USB power bridge (they are cheap and easy to put in if you are only using them for power). it's a step to being able to rig a nice thin USB cable to your steam pod and having some kind of refill tube for bringing the fogging material back up so you could make permanent/semi-permanent installations.
Just way more ways you can take it. (and yes, I understand this is unlikely to happen)
PS when we say in the video "we can't do both" we are referring to making 2 separate molds for the plastic housing. The power actually can come from many different 3v-5v sources.
@Frederik We actually did quite a few prototypes prior to the KS, one design was with a triangular aaa battery holder. We will continue to update, stay tuned!
Good Morning everyone thank you for the comments! This is exactly what we need to hear in order to knock this out of the park :) The update #4 video is exciting news and rest assured we are considering many options on the power supply to the Steam Pod. Since it is powered at 3v-5v indeed we could incorporate a JST connector in PCB that would allow several different methods for powering the device.
The comment that is rising to the top in the poll is the 2" form factor so rest assured we certainly will put that design factor first and foremost in the finished product. Once all the votes are in we will show you a couple different designs that are in the 2" form factor and we can go from there.
Can’t you arrange the AAA batteries in a triangle shape and make it fit 2”?
