Alright, I finally built something that works for this nixie clock (I WILL finish this before school gets out if it kills me.)
I got the frequency generator working, unfortunately, my scope says the frequencies are all wrong
Schematic-
But when I scope pin 9, where I should get 32.678 Hz, I get this-
When I scope pin 1, where I should get 8 Hz, I get this-
And when I scope pin 3, where I should get 2 Hz, I get this-
Would using a fixed 39pF cap cause any issues instead of using the variable cap in the schematic? I know it will be less accurate since it can't be fine tuned, but would it make it THAT inaccurate?
Bad 4060?
Thoughts?
