A pull down resistor has one lead grounded. The table top example I gave is using a pull down resistor. - The benefit of the pull up or...

Agreed. Is there another way to maintain order of contact without excessive complexity? I can see a peg in the end of the plug that...

While we are dreaming of a new type of connector that plugs into the wall for power I would make it triangular and keyed so it's...

The NEC is very concerned about keeping 'everyone else's business' out of the equipment that the rules of the NEC govern. In other...

Great! That's what this forum is for. Refreshing change from those who come here to argue that they can, or already have, broken the...

Current code in the USA requires pretty much every receptacle to be tamper proof as @tech99 described. - If you are serious about...

In the USA low voltage wiring such as data, speaker wires, etc are not allowed to run in the same conduit and eventually receptacle box...

Would it be big enough for 15A conductors? Again, thinking through the sequential connection, when inserting the jack you would briefly...

Don't let @sevensages see you writing that

The circuits are the same. You get the one with the metal tabletop correct but for some reason cannot understand the other.

@Patch Cabbage do you realize that a correctly configured pass transistor(s) act to reduce ripple? Apparently not and apparently the...

This is one of my first real designs for money as an EE. It was drawn by hand (early 1980's) and is a #$@! sight clearer than your...

None of that makes any sense to me.

I never realized it was so difficult to understand. Yes, you could say that there is no voltage source powering anything. Suppose you...

I think this circuit will work the same if you replace all of the transistors with a piece of wire (OK, maybe a forward biased diode)...
