I have tried the one where you cover 2 contacts with tape, the one where you cover 1 contact with tape, and the one where you create a circuit between the 2 pins with conductive ink. None of them worked, whenever I cover at least 1 contact with tape it turns on as soon as power is applied with orange light and no post. If I make the circuit with ink there is no effect.
