What did you do with the rest of the 40106, tie to ground?
Wouldn't it be a good idea to experiment with the circuit more?
To understand it and embellish?
Harry put this out to share and it seems the least we could do is put some work in and build on his foundation.
have the clock be variable.
have an external input for the clock.
add more stages (the 4017 does up to 10 steps)
glide on the output, switchable to select up/down/both
When I built this years ago I forgot to connect the pulse gen to the peak circuits.
It resulted in a more typical EF response, which could be useful and implemented with a simple switch.
Just a few ideas, but we'll never know if these are useful if we just take a person's design and slap it onto a pcb.
