Tiny dazzler Hihat

I found several references about this noise drum module (MiaW I think) and built the Hihat version and it works nicely.

This is the layout I worked off of, I just removed the whole -12V rail and the decoupling because it isn’t needed in this build!
This is the original schematic but I’m not sure it is 1:1 the same as the layout. This one is not verified by me.
