David! I was just taking a look at your Nixie watch diagram, what is the function on the resistor R11 = 510K on the Crystal circuit of the pic. For getting better readings on the output oscillator? Thanks a lot. El lun, 19 abr 2021 a las 19:26, David Forbes () escribió: > My Nixie watches ha

The DS3232 has an internal crystal, with periodic temperature compensation (every 100 seconds). There are also non-volatile trim registers that allow you to fine-tune the trimming even further, though I have not needed to do that. You wont be able to use a scope to fine-tune the crystal oscilla

Hello David! that's awesome, I really like the idea, I just bought an oscilloscope but a really cheap one, the only one I could affort. I will try make some change's on the watch to catch a Via to connect the oscilloscope to it and take a good look to the frecuencia to try to get that 32.768

My Nixie watches have a variable 5-30pF capacitor on the crystal so that I can adjust the oscillator to exactly 32768 Hz. You could use a different value depending on your crystal characteristics. I use an old Hewlett Packard universal frequency counter, running in time period averaging mode, measu
