Hey,
I did a little research again.
Now I use a 5V USB-Supply instead of a 9V battary, so I don't need a DC/DC converter anymore. I can use this IC now for a 74HC4060 as a Counter.
I tried to use MOSFETs only. So if I used them in the wrong way, please correct me.
In the schematic the two blocks on the right are a discrete AND and an AND with one inverted input.
These two "gates" switch on/off and reset the counter. The Q8/9 triggers after about 5/10mins for the on-time, and the Q12/13/14
after about 1,5/3/6h for the off-time.
Or am I on the wrong way?
thanks and regards.
