I think I know how to do the step-down animation, you probably switch anode and cathode in an H-bridge style circuit. Anyway, I think the tubes are really interesting so I bought myself a bunch on ebay. Amazing how cheap they actually are!! Even a complete clock with 4 7-segment displays cost only a little bit.

IN-9 tubes are significantly brighter than IN-13, and to my eyes much better for general use. I made this thing (http://youtu.be/mQ1567EFCY0) with IN-13 and both flavours of IN9. Although the IN-13 were bigger, used less current and were more predictable to play with, the dimmer display meant that version needed a fairly low ambient light environment. FYI IN9 are also more prone to 'sleeping sickness', particularly the argon ones. Cheers, Jon. On Wednesday, November 28, 2012 10:00:26 PM UTC, Michel wrote: Thanks for the info Adam. It doesn't really explain why the current is higher / sensitivity is lower for the IN-9. I still expect the IN9 to be brighter as the higher current should ionize more neon. Maybe I should measure it one day. Michel -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
