I just looked at your images, the 8 is shaped like the one in your B4021 photos, rather than the B8502, so I assume it is the long-lead variant of that. Re. template. Yes, I made a bunch in photoshop(!). I wanted to be able to quickly see which tubes were physical drop-in replacements for which

Re: [neonixie-l] z568m tubes starting to fail

So the hour tube is poisoned on the digits that it doesn't normally display? That could explain it as they would have sat unused for a long time, and I think that running those digits at a higher current for a while would clear them up. But to answer your question: No it doesn't matter - i.e. i

I've got a whole bunch of DT1704A/B/C tubes. They are all pretty dim. Of course, I have no idea how much they were used and I could just be driving them wrong, but the *IV-11* tubes I have are way brighter. Its a bit of a shame as I was looking forward to a making a clock where the digits appea

[neonixie-l] Re: Y1938 blue-coated VFD

Not sure how I was driving them before, but they are plenty bright enough now. I suspect it was the segment current. Before, I was using a voltage divider on a 50V supply. This time I used one of my own flyback power supplies with the output voltage configured for 27V. I'm not sure why I didn't

You could prototype it on your 3D printer, then use shapeways to have it made in a better material. On Thursday, July 19, 2018 at 4:36:02 AM UTC-4, MrThe50sanchez wrote: > > > Hello everyone! > > I was trying to figure out how to make the case of the watch, maybe, >

[neonixie-l] Re: IN-18 nixie tube mirror signs in the windows of the tube?

Tubes don't last forever. The surface of the numbers gradually erodes and is deposited on the glass. This glass darkening is an indication that the tube has been used a lot. I think the windows in the grid on IN18 tubes provides a safe place for this to happen - I have seen unused tubes with da

Hi Alic, the OP says the clock has been on continually for 5 years. Not sure what one should expect after that length of time. One of my clocks is coming up on two years, though I may have lost track of time. On Tuesday, July 31, 2018 at 3:48:20 PM UTC-4, Alic wrote: > > Hello, > The opening in

[neonixie-l] Re: Pandicon ZM1200 in Action!

Pull Anodes to ground with a 100K resistor so it drops to zero fast. Pull cathodes up to at least +75V via a 330K resistor - so they come off zero fast. 75V-90V is a good off-state for cathodes. I'll take a look at my timings too. On Tuesday, July 31, 2018 at 3:40:01 PM UTC-4, SWISSNIXIE - Jona

And I see the HV513 does the last part for you. What do you have VPP set to and how fast does it push the cathodes up to VPP? On Tuesday, July 31, 2018 at 4:52:27 PM UTC-4, Paul Andrews wrote: > > I should add: This is not for a ZM1200, just a bunch of multiplexed IN12s. > > On Tues
