Adding a source of stray photons works too - a blue LED aimed at a gas tube stabilizes it nicely. However, that might detract from the glow, if it's used in a visible way. Perhaps a near-UV LED would do the trick. Easy enough to try out. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
