Instructables user Kipkay has a project that claims to block IR signals from any receiving device. For example, prevent someone from changing channels on a TV. This magic is achieved through scrambling the remotes IR signal. Based on a 555 Timer IC, Kipkay states that this circuit can be innocuously housed inside a standard remote control for activating/deactivating its IR signal jamming function.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
