day9: new approach


nd the final result of al this work is: ... it didn't work
I couldn't get the computer and the manual buttons operate at the same time. after some fiddeling with or-gates and different pull-up/down methods I had enough and threw it in a corner.
Only after a year or so I was bored enough to give it another try, This time without logic, the webserver is on all the time. Maybe add a microcontroller one day.
So now I have replaced the 7476 gates with buffers, and it all works.

here is a picture of how the system looks like.



next: finish the 230V part and casing.
