Hi, I'm thinking of creating a Nixie clock controlled by mechanical 5V relays.
I won't do anything fancy, just static drive with the Nixie anode connected to 180VDC through a resistor and one relay for each cathode. The relay coils will be connected to uC pins via either individual transistors or perhaps a darlington array. Like so: 180V | R (anode resistor) | Nixie | ... | 1 relay for each cathode (connected to GND) Schematic here: https://www.dropbox.com/s/r67bnrz09b4xivv/relay-nixie-test-board.png I'll probably use IN-4 tubes, but that may change. I have two questions: * Does my schematic look sane? * Can anyone recommend a relay to use? I'm looking for a relay that can be switched from 5VDC. There are many available in small form factors, but most seem to be rated for 250VAC/30VDC or similar. (I guess a relay rated for a lower DC voltage might be ok too, since it will only pull 3-4mA) I want a mechanical relay... since the main point of this exercise is to get the clicking sound when the relays switch. Thanks in advance. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
