Funny I immediately dismissed this idea originally because I always think "H-driver" for DC-to-AC; using 4 switches. For my clock this would have been too costly. I didn't realize that replacing the upper 2 switches with resistors was perfectly fine and resulted in negligible wasted energy.
In the case of my big clock, the PCB layout & routing was too dense in 2 layers to use 2 resistors per bulb, even using resistor SIPs (though SMT would have been fine). WIth a high-enough DC supply, I could connect bulbs in-series (which saves on resistors). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
