Shop Vac Auto Switch Enclosure

When I do woodworking in my garage I connect a shop vac to my tools to help suck up all the saw dust created when I make cuts. This requires me to remember to turn on the shop vac switch anytime I want to make a cut. There is a device called an auto switch to help solve this problem, and I made one from scratch using an arduino microcontroller, a current sensor, and a relay module.
