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.

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.

That's the whole point - it all comes ready wired so no soldering or mucking about - it's modular so easy to build & fix.

Brilliant! :-))
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?

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.
I presume you have a water reservoir in the bottom of yours, how much does it hold?

Anyone ever found a UK supplier for the ultrasonic units yet? The small ones all seem to need importing.
