power supply is at 170 can run up to 200v i played with the anode resistor didn't seem to matter Nixie's are japanese vintage i had laying around
the r c value is the mux timing using the values that are normally used with led or numitrons does not work had to change too 150k and .0047 uf cranking up the hv supply i start to get some ghosting with the other digits i am using a coupling capacitor from the 5309 to the digit driver transistors i don't think i am current starving the tubes but that i need to check i may try some other nixies i have i just was wondering what values some one has used if they ever used the national clock chips with nixies thanks jerry On Jul 27, 9:08 pm, David Forbes <[email protected]> wrote: > On 7/27/2011 6:26 PM, jerry kimento wrote: > > > i made a nixie clock using the MM5309 chip > > using the BCD out to drive a 74141 > > my question is ... i cant seem to get the nixies to display very > > bright > > > i did have to play with the c and r values to get it to look readable > > but i would like it brighter > > > has any one ever used the mm5309 or mm5314 chips > > > thanks > > jerry > > Jerry, > > Nixie power supply voltage? Anode resistor value? Type of nixie tubes? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
