Re: [neonixie-l] UFO Nixie Clock

Hello Andy, I read your recent message about the mechanical neon clock you have. I’ve seen something like this awhile ago but I can’t remember a lot of the details or appearance of it. Would you be considering selling this? As a member of the Neonixie group, I am just crazy enoug

Re: [neonixie-l] What's the best approach for this?

Hi martin, Congratulations, that’s a terrific calculator to receive as a gift! The high anode voltage required for the display is generally provided by an inverter powered by the DC input. From the pictures, it looks like there is a transformer just behind the display. That is likely fo

Hello everyone, In my obsession with Nixie calculators, I recently acquired a Dietzgen ESR-1 which is a rebranded Casio FX-1. It required the usual replacement of the power supply HV caps and a pass transistor and cap in another regulator circuit. After all that, it is still 95% DOA. Thi

Re: [neonixie-l] identification request :unknown edge lite displays

Hello, I have a big old General Radio automatic capacitance bridge that uses these type of displays plus some that display special characters. I’ve been looking for some circuits/plans to make a clock with these. When you finish your clock project could you post your design plans? Thank y

Re: [neonixie-l] New find!

When RCA was in its heyday, they promoted their "RCA Institutes” correspondence courses in electronics. As part of the course in TV/radio servicing, the students had to assemble their own test gear. This was one of those items. It is actually a rebranded Eico model 430 oscilloscope from the lat

It sure looks nice sitting there with the “others”. At my age, you can guess which readout I prefer! And it seems accurate, too. Very good work. Rich > On Feb 6, 2022, at 2:45 PM, martin martin wrote: > > Restoration completed. Old glue and tape cleaned on the face. As you can see > the numbe

Re: [neonixie-l] El Dorado Frequency Counter Restoration

Thanks for that link Bill. It definitely needs TLC - a lot of it! I’ve never seen that model before, but if you look closely you’ll see that it doesn’t use LED’s but rather Panaplex displays (my favorite). Wish it wasn’t rack mount, cheaper and in better shape or I might have went for it just for

Re: [neonixie-l] El Dorado Frequency Counter Restoration

Hi All, Does anyone know whatever happened to Eldorado Electronics? I wonder if they ever made a counter or DVM that didn’t use Nixies. Don’t recall ever seeing any but maybe the group has some info. Rich > On Feb 4, 2022, at 6:28 AM, Bill Notfaded wrote: > > > Amazing it looks like

Re: [neonixie-l] El Dorado Frequency Counter Restoration

Hi Everybody, El Dorado made some pretty nice counters back in the day, a few of which I have owned at one time or another. This example seems to be in better condition than most you see now. I don’t know if there ever was an El Dorado counter that didn’t use Nixies. Perhaps some members

Re: [neonixie-l] Now it's time for some "real" neon!

Greetings everyone, I thought the group might appreciate my latest toy. It uses genuine Beckman displays SP-351 & SP-353 to show 4-1/2 digits. Data Precision was located in Wakefield, Mass. until sometime in the 80”s. Does anyone know any details about the company or its demise? I have

Re: [neonixie-l] Sperry Planar Display

Hello all, Does anyone know the significance of those Sperry displays having the part# etched as “EX-332” rather than the more familiar “SP-332” ? I was wondering if the “EX” might mean “experimental” but I’ve not seen anything like that on Panaplex displays before. Any ideas? Rich

Re: [neonixie-l] Looking for a PANAPLEX display driver module

Hi Terry, I have never seen it done with this type of “hard forming” dipped encapsulation. There might be the chance of dissolving the innards along with the epoxy! I’ve seen epoxy that fills a mold to cover parts and I think that is dissolvable but I can’t be sure. In any case, this i

Re: [neonixie-l] Looking for a PANAPLEX display driver module

Hi Martin, I’m sure Burroughs used (and maybe designed) these modules since the Panaplex was their creation. I have a schematic for a similar Victor calc model 18-1721 and mine is 18-1441. They are mostly identical except the 1721 has scientific functions and somewhat different logic b

[neonixie-l] Looking for a PANAPLEX display driver module

Hello all, Does anyone have any knowledge of these packaged electronic circuits (PEC’s) that are used in VICTOR calculators with PANAPLEX displays? The VICTOR part number is shown in big numbers and the smaller number's significance is unknown. I have a unit that is missing the top-le
