I found that out when I started taking photos of my nixie projects. Usually taken with a tripod mounted camera, at a very slow shutter speed (No flash). The nixie tubes glowed bright yellow in the photos, though we all know that they glow a pretty orange. Took months of screwing around to get it right. That could just be, because I'm a lousy photographer. Here's a data sheet on regulator tubes: http://frank.pocnet.net/sheets/127/0/0A3.pdf The 0B3 is suppose to regulate at 90V. A 125V minimum supply voltage is recommended. 30mA max for this tube, though most of the regulator tubes this size can go up to 40mA. Note that you have it hooked up correctly. The cathode (-) is the big cylinder, with the anode (+) being the skinny rod down the middle. Since it is a gas filled cold cathode device, it can suffer from cathode poisoning. Burn it in for a while, and see if the glow spreads out uniformly. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
