Very nice,The standard voltage you can expect to find on the power lines of anything USB (those handy sockets that everything that plugs into your PC through these days) is 5 volts. The various versions of USB (original USB, white plug tabs, USB2 black, USB3 blue) can supply different levels of current, but all at 5 volts. Because terminating is a fiddly and error prone job, USB leads are best bought ready to use, the main problem is figuring out which actual plug you want on the ends of the wire.
Being somewhat dense when it comes to anything electricery, can you show us what and where things go to make one please, and where to buy the bits.
Yours runs off a USB, so is that 3 volts?.
Regards,
Len.

Congrats plastic, simple and really effective. I've ordered 2 misters, one to use, and one to experiment with. I want to find out if the mister will handle 6 volts, and for how long.Why run it on 6v? The little DC-DC converters create 5v USB from any input - 4-40V for less than £1 saves cutting wires and messing about.
I presume you have a water reservoir in the bottom of yours, how much does it hold?

I want to find out if the mister will handle 6 volts, and for how long.If it is USB, almost certainly not for long at all. 5 volt UBEC power supplies that are happy to run off 6 volts are available and cheap.

Anyone ever found a UK supplier for the ultrasonic units yet? The small ones all seem to need importing.Any available here will have been imported, and will not benefit from the Chinese post subsidy and will have gained UK handling costs.
Brilliant! :-))Tank is 70mm-ish by 25mm-ish - and I wouldn't trust any of the Chinese specs for current consumption - I'll bet they're all out of the same factory - remember the 320A ESCs?
I notice that the smoke unit that you link is rated at 0.3W but that there is another (link below) that is rated at 2W & costs £1.89. Whether this means that it produces nearly 7 times as much smoke is open to wild speculation.

Do you have any thoughts on this?
How much water do they actually vaporize - how big a tank do you need?

Have you remembered that a 6v battery gives a lot more than 6v when fully charged?I have lots of different batteries, all different voltages so the USB psu standardises all that ancillaries to 5v
A fully charged 6v lead acid gives around 6.37 volts
A fully charged 6v 5 cell NiMH pack gives a maximum of around 1.45v per 1.2v cell so say 7.25v.
I agree with Plastic that a Voltage UBEC controller is a good idea.
