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.][1] You can find the source code [on Github][2]. You can find the models [on Thingiverse][3] [1]: https://youtu.be/wdke-Im5TWA [2]: https://github.com/nickkoza/SwiftCarve [3]: https://www.thingiverse.com/thing:2737512
