Yeah, you need an inverter for the BCD though. On Friday, June 19, 2015 at 1:55:55 PM UTC-7, wb9jfr42 wrote: > > Has anyone built a clock using MM5309 or 11 chip with nixie tubes > Using BCD to a 74141 but don't seem to be able to multiplex > > i would like to use the chips that i have had for man

Years ago, I built a small cube, for a friend, as a gift. It was 2.5" or 3" to a side, and made from 1/8" white translucent acrylic. Common stuff. The light came from 4 superbright LEDs (red, yellow/amber, green, and blue). The super brite blues, and greens, just came out, so it had to be ~1995.

[neonixie-l] Re: Seven digit Nixie project

As long as you're using a microcontroller like the PIC or AVR, and not an 8051 variant, why not use charlieplexing ? Look at page 4 in this document: http://nixietube.info/NixieTransistors.pdf In your code, you twiddle both the port and its DDR bits. It can turn only one output ON at any time.

Very Clever ! Never thought of using a "1" & "0" as an "I" & "O", though I lived in the era of typewriters, where many portables did not have a "1", or "0". You used the similar shaped letter, instead. Usually a lower case "L", for the "1". On Tuesday, July 21, 2015 at 1:35:02 PM UTC-7, PsyPhi

As the translation shows, 425V is the recommended minimum supply. But remember Soviet tubes seem to be spec'd conservatively. I guess they didn't want end up in the gulag ! After tinkering with them for a while, I found the A101 to be a particularly forgiving dekatron. I've run them with a 350V
