Nixie car gauges

[David Forbes]

I built a Nixie tube instrument panel for my Corvair a couple of years ago. It's a big PC board with a couple dozen 4998 and 5870 tubes, with a separate control box. It worked very well (no vibration problems or anything), so I transferred it into my Volvo 544 shortly after I reacquired the car last year. It's working well in there too, but I'd like to rearrange the gauges to fit the car's instrument cluster. 

To this end, I'm redesigning it to be modular instead of a monolithic board shaped to fit the car. Each gauge is a little PC board with an HV66 driver and SPI daisy chain ribbon connectors. 

The plan is to be able to position the modules in the original cluster housing as best fits the car. The software is going to have a header file that's customized to the car. Trim pots on the box allow in-use calibration of those parameters that need it, such as speedometer and temperature. 

Do any of you with old cars think you'd be interested in this?

Photos please! I absolutely love the idea!!

I wish I owned a PV544 (or a PV444 with split windows).

What about the Flux capacitor?

That's great work. I regularly drive a PV544, but it's slowly dying, and I will need to rebuild the engine soon (and that's just the tip of the iceberg...).

I would love to see a picture of your display once it's in the PV.  Jim

Fabulous!

If I ever do that I plan to have an IN13 as a progress meter for 0-60 timed runs in there somewhere 😁

An average speed mode ( with a “start averaging now” button ) would be great for some of the stretches of motorway that have average speed cameras here in the uk too.

Cheers,

Robin.

Or just install a rotating license plate.  But I guess that was really only standard in an Aston Martin...
