THIS DRY-ICE POWERED FOG MACHINE IS PERFECT FOR HALLOWEEN




The leaves are turning brown, and the spookier season is upon us. If you’re currently working up plans for a top-notch Halloween party, you would do well to consider building a fog machine like this unit from [DIY Machines]!

This fog machine is based around dry ice, so you’ll need to source that from an external supplier. The machine consists of a closed container filled with hot water, inside which is a movable bucket filled with dry ice. By lowering the dry ice into the water, fog is produced.




An Arduino is used to control the bucket, allowing the amount of fog produced to be controlled with a smartphone app. There are also controllable LEDs built in to give the fog a suitably eerie glow. The build relies on a series of 3D printed parts for the mechanism, and features several different nozzle designs for achieving different effects, such as a rising geyser or a thick low-lying fog.

The basic concepts are simple and it’s a build anyone could knock out in a weekend with a 3D printer and an Amazon account. It’s a great way to add to the ambience of Halloween, but of course, that’s not all fog can do. Video after the break.
