[sdiy] Fast optical device to replace slow responding LED/LDR combo.. ??

[Jean-Pierre Desrochers]

I used H11F3 in the past and they too are slow..
I tried to use them as a voltage controled volume

but they bring distortion in the audio path..

Could you maybe use an H11F3 or similar in your application?

Is there any device that could replace a slow responding LED/LDR combo ?

I was thinking of this LED/photo transistor/bridge replacement..

The only thing to be carefull about would be the diodes voltage drops,

But using very low current that voltage drop could be very low..

Hmmm..
