I've collected a number of one-of-a-kind Russian VFD panels, constructed with laminated-glass technology similar to the UDT-3. I'd like to try to light some of them up and eventually turn them into conversation pieces.
First question is the filament. The active display area is around 4" x 3.5", with multiple parallel filament wires running down the long axis. I don't want to over-drive the filament and burn out the display. Also, am I going to have a brightness gradient across the display if I drive the filament with DC? Each of the actual elements that lights up is typically quite small - there's probably 70 or more individual elements in there. Most are the normal blue-green VFD color, though there are some pure green ones and even a few red ones. The only picture I have of the display being lit just shows the filament pins connected to an out-of-picture power supply, and all of the elements and the grid tied to each other with a strip of foil. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
