Hi all, That's my first post, but I hope I get an answer to my huge beginner problem. So, I've recently started to build my own Nixie clock. I have four LC-531 <http://www.tube-tester.com/sites/nixie/data/lc-531.htm> nixie (Polish production) gathered from old Unitra Multimeter. All of them works fine when I'm trying to connetct it to HV source (Voltage converter 9V->150-220V - schematic <http://mirley.firlej.org/files/P9150_Schemat.gif>) I'm using ~*180-190V *and *10k* resistor (*is it good?*).
Few days ago I finally get some 74141 and I was trying to test it, so I connected it to ATtiny2313 like this: <http://i.imgur.com/1a6Lw.png> and program MCU with that code <http://pastebin.com/j62JTyVv>. It should count on Nixie lamp from 0 to 9 (2 sec per digit). Double checked all my connections and* as the result I've got Nixie lamp with all digits glowing in the same time. * I also checked 74141 using LED diods (+ to 5V and - to 74141 outputs) and it works fine (diodes light one after another) *Any suggestions what I'm doing wrong? It seems to in some way all outputs are connected to GND when using HV to my nixie (works fine with LED).* EDIT If I'm missing any electronic part here, please provide me info how to connect it and how it will help, I 'm Software Engineer and unfortunately, I'm not good in whole electronic stuff (yet :) ) -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
