In the spirit of nixies, though, you could redo the entire design and use NE-2 bulbs. I've driven NE-2's with opto-triacs on a few projects, which allows you to safely (ie, with proper isolation) control AC-line voltages from digital logic. The MOC3021 has 5kV isolation and costs about 50 cents.
I cant see the rest of the schematic, so I would assume it's NOT safe to replace 6.3VAC with 120VAC, and replace the bulbs with NE-2 bulbs that have a built-in resistor. Besides, the bulbs would be running on DC, rather than AC so they will appear less-bright with only one electrode glowing, rather than 2. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
