 		 #75552 - RE: Wide voltage led (a little O.T)
Responding to: ???'s previous message
hi,

My first idea was somethink like this

...and it is wrong. In fact, you need exchange 4N32 and resistor 2K2. Your schematic as it is, provides 3V on resistor while 220-3=217 Volt is at optocoupler.

Regards,
Oleg
