SwiftCarve - Halloween Saw Prop

I developed this arm-mounted circular saw as part of a mad doctor Halloween costume this last year. Along with the spinning foam blade it also features a smoking effect, lights, and sound. It's all coordinated by an Arduino Nano mounted in a custom PCB. The smoke effect is provided via a modified vape pen.
