Description

This circuit powers an arm-mounted circular-saw that I developed for a mad doctor costume this last Halloween. 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 this PCB.

WARNING: This board layout still has a bug in it. Two of the pins on the FQP30N06L mosfets are flipped. I let EasyEDA know about the issue and they've fixed it in the templates, but this original board layout still has the issue.

There's also an issue where I apparently ran a power line a bit close to some source of noise, so I ended up having to put a 470uF capacitor across the power lines into the LM386 to filter the power. You can see this reflected in the schematic but not the board layout.

You can find a video of the prop on YouTube. You can find the source code on Github. You can find the models on Thingiverse
