Yep. Although not related to this kit specifically, a friend of mine built a energy meter much like a kill-a-watt using a raspberry pi. It plugged into 120 vac on one side, and usb to computer on the other side. He didn't end up doing enough to isolate the 120 vac side from the usb side and fried his computer. It was pretty impressive damage as it managed to fry the motherboard, CPU and memory.
