Leadingzero writes – “Several projects on this site involve the modding of consumer electronics for new and inventive purposes. The NES tv remote for example used an old remote control as the base of the whole project. However, the circuitry inside was diverted to the controls of an old NES controller. This process of redirecting the internal circuitry of a component is what I call “circuit hijacking” because essentially, the circuitry is “hijacked” to a new location and purpose. This method is by no means new, nor is it even difficult but in this article I will attempt to described the best ways that circuit hijacking is accomplished so you can begin hijacking your own circuits.” Link.
HOW TO – Circuit Hijacking
