Hi, ericgibbs,
Sorry.
No idea. I wandered that too. I tried getting in touch with the
original author and nothing came out.
I saw your idea and I like it.
Thanks.
Tomorrow I'll draw it all: the tree button groups, the additional parts you've
added and see what will come out.
When I'm done I'll show you what came
out as a whole picture.
What would you say about my offer to simply switch the "+" and "-" lines
of the schematic so that at the outputs goes positive impulse? Is it a bad
idea? Is this going to work at all? Or it's just nonsense? I am asking beacuse
the switches (MAX333ACPP) are positive triggerd, I think. I should have
mentioned that earlier.
My bad.
