Hi Spec, hi everyone,
So many thanks for your thoughtful replies!
I am a bit confused about the placement of the diode. I thought reverse bias has to be applied to the diode which would then be fed into the schmitt trigger ... but here I cannot see how the diode can act as a gate for the whole setup...? Also, especially since the diode should have three anodes, thus three outs, one for each colour, which in my schematic would be fed into the three different triggers.
Could you elaborate on that?
I am also confused about one of the resistors. R27, what purpose does it serve and what value would I need to pick for it?
Also, I am based in Germany and I can neither seem to find the OPA192 nor the OPA197 at the biggest (and only) German circuit parts retailer (
www.conrad.de) ... can you think of an alternative that might be available here?
This doesn't account for the resistors and condensators I use for the schmitt trigger, right? everything in the schematic goes before the schmitt trigger, correct?
As for my age, I have to apologise ... I am afraid I am not 98! It's a standard that I pick on all my accounts and now you caught me off guard with your sincerity.
Apparently I cannot change it anymore, but I updated my location...! Apologies for the confusion.
Again, many thanks for your help already, this is very lovely of yous.
Best,
G
