You must begin with an existing device: you cannot create something from scratch. You always work alone, without assistants, and you must focus on the task while doing it. The resulting device must be a plausible derivative of the original one, with a primary purpose of hurting people. (For instance, your electric "joy buzzer" was originally a hand-held medical diagnostic unit that read someone's condition on touch.)
