Yes, processor = MCU. Using an NE555 would be no problem, I'm using standard TTL for the logic of the clock itself. I know there is one dimming circuit which uses the NE555, this one: http://www.mcamafia.de/nixie/ncp_dt/nix_dim.htm but that doesn't use an LDR.
If I remember correctly the design made use of triangle waveforms and a comparator which compared against the LDR. I've found a few similar designs when googling, but nothing that was designed for Nixies like the one I found several years ago. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
