What?
Yes and no, I’ve tried working with making hunter killer drones that use this. Not useless but this should maybe be behind illegal tech, emagging the printer, or possibly behind one of the advanced grenade technologies. Especially considering if you really want to, can create a circuit to chain stun people with an advanced release flashbang for whatever reason.
As for other parts of circuits, they are a pain to produce(because their UI sucks), they are either a trivial gadget nobody notices, something that benefits only you, unfun weird deathbots.
or an experimental circuit which winds up accidentally blinding yourself and a coworker who walked into the room you were testing in for a solid minute.
