I was assuming some kind of 3.3V or 5V logic, like an esp32 or an arduino. I don’t mess around with big power circuits at all. If I inject power it’s going to be pretty low wattage. Sorry for the confusion.

Ya. I don’t run more than 5A (basically a usb) through 3d printed stuff for that reason. Filament is designed to melt.

Dude, if your commander orders you to invade Canada, hate to break it to you, but that’s lawful. Now if they tell you to use chemical weapons or target civilians you can push back on that. The law they are referring to is United States law and a couple of conventions like the Hague and Geneva conventions which cover war crimes. Other international law doesn’t count. Nato treaties don’t mean boo when it comes to the lawfulness of orders, nor should they.
