Hello,
I was experimenting with old LED schematics where I ran LED off of outlet.
(AC)-C-|>|-R-(AC)
C=0.1uF
R=120 ohms
It used to be 0.47uF which was too bright so I toned down. What I am wondering is that in JED's post, he uses another LED connected parallelly but in opposited direction. I did not have LED so I used a rectifier but LED did not light up. ... so I left as above.
I think it is bad since C must charge at breakdown region of LED (beyond reverse bias). I know it's ok to swing Vdiode all over the place as long as I don't blow them, but I am not sure in this application.
Thanks in advance,
Tomo
