I want to build tiny concealed fog machines for miniature dioramas and gaming boards! I’ve done lots of googling, but I’ve also never done anything involving electronics before and would appreciate some guidance as to where to start.
Project criteria:
• The whole package should be as compact as possible, to make it easier to conceal/camouflage.
• I think I’d like to make several low powered units that produce small amounts of fog, rather than one large one.
• I don’t want to leave any residues on miniatures/dioramas, so a system that uses water rather than smoke oils is essential.
• I don’t need any fancy features, like variable power or a fan – a simple on/off switch should be fine…?
• ‘Self contained’ i.e. battery powered is preferable for the following reasons:
1) I want to be able to easily move around and reuse the units on different boards.
2) I want to minimise visible cables, or minimise the necessity to disguise cables.
…That said, it’s not impossible to disguise cables, so if there’s a discrete and convenient way to power several modules at once from a wall outlet, I’m open to ideas.
I’ve been googling ultrasonic water modules, but it’s tough to get a sense of their scale, power requirements, and suitability for my plans. If anyone can give me a point in the right direction, I’d be super grateful!
