They're MPS42s. I can identify the other parts.

Re: [neonixie-l] Recommendations for a Nixie tester/cathode de-poisoner?

2024-01-10 Thread HikariFaith 
My recommendation would be to order a PCB of something that's already been 
made. The clock I'm currently working on is based off the design shared by 
CNLohr which is really compact, simple, and low in part count. Personally, 
if I were to make the design into a more universal tube tester and cathode 
de-poisoner, I would make the pinout a separate interchangeable module that 
can be plugged into the base driving board. That way any pin configuration 
could be accommodated. If there's interest in it more generally, I would be 
happy to modify my own variant of the design into something barebones that 
can be used for this exact purpose. I'm sure there's others out there who 
are looking for an affordable tube tester/de-poisoner.

The Pro Nixie Tester is also not available. That's actually the one I had
been looking at.  I could roll my own from the schematics, although I'm not
sure what transistors he's using. IIRC, I had used MPS42A's in a
MSP430-powered NL840 design I had done at one time. There might have been a
couple of other parts in the schematic that are a little vague but could be
worked out.

I need to go through the tubes again and verify it against my spreadsheet.
I'm pretty sure I had entered everything I had, and I don't think I have

There is a newer model available. It uses interchangeable sockets for different 
tubes, no fooling around with loose wires all of the time (site is slow to 
load):

The build quality is a bit flimsy but it works. You can always roll your own 
using the schematics.

This unit isn't that fancy but it does have connections for external voltmeters 
and ammeters. I've yet to get around to building a meter panel for it.

[neonixie-l] Recommendations for a Nixie tester/cathode de-poisoner?

2024-01-09 Thread J.C. Wren 
Greetings.  It's been a long time since I've participated in the neonixie-l 
group. Having retired and having free time on my hands, it's time to do 
something with the stash of tubes I've been sitting on for years.  My 
intention is to put those tubes in a few clocks I'll design, but before I 
do, I'd like to go through and test them all. 

What's the latest and greatest Nixie tester that supports cathode 
de-poisoning? I've seen a couple on eBay that seemed a little more basic 
than I'd like, and the one from nixietester.com that's no longer available. 
I'm not particular if it's a kit or fully assembled. It would be nice if it 
has a smart de-poisoning algorithm, such as the one described for the 
bi-quinary tubes by Mark Smith. In a perfect world, it would datalog the 
current and voltage for each segment.

The tube models I'd like to test are IN-18, ZM-1040, NL-840, 1970-0009, 
B-5092, B-7971, and NL-5859CS. The first three are the critical ones, as 
they're my favorite tubes :)

Any and all recommendations appreciated!

Thanks,
--jc
