    12v receptacle

    Ill just jump right to the question. Is there a good reason no one uses a standard double prong receptacle with 12v applications? The only standard receptacle that i know is used for 12v is a cigarette lighter in a car. Or atleast it looks like one. Havent we moved on to a more standard looking...

    PIR

    Can the output on a PIR sensor be solid? I need it to power an npn transistor to switch a relay. But i cant have it pulsing and interupting the transistor therefore flipping the relay on and off. Once triggered i need it to stay on.

    A question about electrical Theory

    Im just curious here. This isnt anything im working on. I was sitting back thinking and it occured to me... I know Power=Voltage X Amperage and when either voltage or current is increased, so is the power. Now this may not be a real life scenario but if the power in a circuit is increase (not...

    Pickit 3 vs Arduino uno

    I realize this is going to start a massive argument.... That being said, im torn between the two. Im leaning towards pickit because im not sure you can use different uC with arduino. Only the one that comes with it. I want to be able to use a variety a controllers. Correct me where im wrong...

    Salvaged components
