Hi everyone, first time here so hopefully, you'll look after me.
I've had a look around the site for a simple circuit that can illuminate an LED to show that there is a current flowing to a load and then for it to change colour when the fuse has blown.
All I can find on the forum are circuits that are for 5v or 12v.
I have seen some circuits on the web and these use 1n4007's with a 100k resistor on the Neg line of the mains.
I'm no genius, but doing it that way would cause alot of heat from the resistor and I'm after reducing the heat as much as I can.
Back in the good old days I used neons and resitors to do the job but what with health and safety I'd rather be safe than sorry.
If I can get a circuit that suits me, I want to be able to transfer it on to a PCB so that it can be mounted inside a case.
So, if anyone out there has any ideas as to a safe and stable circuit I would be grateful.
